    Animated Faces for Robotic Heads: Gaze and Beyond2011Inngår i: Analysis of Verbal and Nonverbal Communication and Enactment: The Processing Issues / [ed] Anna Esposito, Alessandro Vinciarelli, Klára Vicsi, Catherine Pelachaud and Anton Nijholt, Springer Berlin/Heidelberg, 2011, s. 19-35Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We introduce an approach to using animated faces for robotics where a static physical object is used as a projection surface for an animation. The talking head is projected onto a 3D physical head model. In this chapter we discuss the different benefits this approach adds over mechanical heads. After that, we investigate a phenomenon commonly referred to as the Mona Lisa gaze effect. This effect results from the use of 2D surfaces to display 3D images and causes the gaze of a portrait to seemingly follow the observer no matter where it is viewed from. The experiment investigates the perception of gaze direction by observers. The analysis shows that the 3D model eliminates the effect, and provides an accurate perception of gaze direction. We discuss at the end the different requirements of gaze in interactive systems, and explore the different settings these findings give access to.

    Auditory visual prominence From intelligibility to behavior2009Inngår i: Journal on Multimodal User Interfaces, ISSN 1783-7677, E-ISSN 1783-8738, Vol. 3, nr 4, s. 299-309Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Auditory prominence is defined as when an acoustic segment is made salient in its context. Prominence is one of the prosodic functions that has been shown to be strongly correlated with facial movements. In this work, we investigate the effects of facial prominence cues, in terms of gestures, when synthesized on animated talking heads. In the first study, a speech intelligibility experiment is conducted, speech quality is acoustically degraded and the fundamental frequency is removed from the signal, then the speech is presented to 12 subjects through a lip synchronized talking head carrying head-nods and eyebrows raise gestures, which are synchronized with the auditory prominence. The experiment shows that presenting prominence as facial gestures significantly increases speech intelligibility compared to when these gestures are randomly added to speech. We also present a follow-up study examining the perception of the behavior of the talking heads when gestures are added over pitch accents. Using eye-gaze tracking technology and questionnaires on 10 moderately hearing impaired subjects, the results of the gaze data show that users look at the face in a similar fashion to when they look at a natural face when gestures are coupled with pitch accents opposed to when the face carries no gestures. From the questionnaires, the results also show that these gestures significantly increase the naturalness and the understanding of the talking head.

    Furhat goes to Robotville: a large-scale multiparty human-robot interaction data collection in a public space2012Inngår i: Proc of LREC Workshop on Multimodal Corpora, Istanbul, Turkey, 2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the four days of the Robotville exhibition at the London Science Museum, UK, during which the back-projected head Furhat in a situated spoken dialogue system was seen by almost 8 000 visitors, we collected a database of 10 000 utterances spoken to Furhat in situated interaction. The data collection is an example of a particular kind of corpus collection of human-machine dialogues in public spaces that has several interesting and specific characteristics, both with respect to the technical details of the collection and with respect to the resulting corpus contents. In this paper, we take the Furhat data collection as a starting point for a discussion of the motives for this type of data collection, its technical peculiarities and prerequisites, and the characteristics of the resulting corpus.

    SynFace Phone Recognizer for Swedish Wideband and Narrowband Speech2008Inngår i: Proceedings of The second Swedish Language Technology Conference (SLTC), Stockholm, Sweden., 2008, s. 3-6Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    In this paper, we present new results and comparisons of the real-time lips synchronized talking head SynFace on different Swedish databases and bandwidth. The work involves training SynFace on narrow-band telephone speech from the Swedish SpeechDat, and on the narrow-band and wide-band Speecon corpus. Auditory perceptual tests are getting established for SynFace as an audio visual hearing support for the hearing-impaired. Preliminary results show high recognition accuracy compared to other languages.

    Spontaneous spoken dialogues with the Furhat human-like robot head2014Inngår i: HRI '14 Proceedings of the 2014 ACM/IEEE international conference on Human-robot interaction, Bielefeld, Germany, 2014, s. 326-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We will show in this demonstrator an advanced multimodal and multiparty spoken conversational system using Furhat, a robot head based on projected facial animation. Furhat is an anthropomorphic robot head that utilizes facial animation for physical robot heads using back-projection. In the system, multimodality is enabled using speech and rich visual input signals such as multi-person real-time face tracking and microphone tracking. The demonstrator will showcase a system that is able to carry out social dialogue with multiple interlocutors simultaneously with rich output signals such as eye and head coordination, lips synchronized speech synthesis, and non-verbal facial gestures used to regulate fluent and expressive multiparty conversations. The dialogue design is performed using the IrisTK [4] dialogue authoring toolkit developed at KTH. The system will also be able to perform a moderator in a quiz-game showing different strategies for regulating spoken situated interactions.

    The Furhat Social Companion Talking Head2013Inngår i: Interspeech 2013 - Show and Tell, 2013, s. 747-749Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this demonstrator we present the Furhat robot head. Furhat is a highly human-like robot head in terms of dynamics, thanks to its use of back-projected facial animation. Furhat also takes advantage of a complex and advanced dialogue toolkits designed to facilitate rich and fluent multimodal multiparty human-machine situated and spoken dialogue. The demonstrator will present a social dialogue system with Furhat that allows for several simultaneous interlocutors, and takes advantage of several verbal and nonverbal input signals such as speech input, real-time multi-face tracking, and facial analysis, and communicates with its users in a mixed initiative dialogue, using state of the art speech synthesis, with rich prosody, lip animated facial synthesis, eye and head movements, and gestures.

    Furhat: A Back-projected Human-like Robot Head for Multiparty Human-Machine Interaction2012Inngår i: Cognitive Behavioural Systems: COST 2102 International Training School, Dresden, Germany, February 21-26, 2011, Revised Selected Papers / [ed] Anna Esposito, Antonietta M. Esposito, Alessandro Vinciarelli, Rüdiger Hoffmann, Vincent C. Müller, Springer Berlin/Heidelberg, 2012, s. 114-130Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this chapter, we first present a summary of findings from two previous studies on the limitations of using flat displays with embodied conversational agents (ECAs) in the contexts of face-to-face human-agent interaction. We then motivate the need for a three dimensional display of faces to guarantee accurate delivery of gaze and directional movements and present Furhat, a novel, simple, highly effective, and human-like back-projected robot head that utilizes computer animation to deliver facial movements, and is equipped with a pan-tilt neck. After presenting a detailed summary on why and how Furhat was built, we discuss the advantages of using optically projected animated agents for interaction. We discuss using such agents in terms of situatedness, environment, context awareness, and social, human-like face-to-face interaction with robots where subtle nonverbal and social facial signals can be communicated. At the end of the chapter, we present a recent application of Furhat as a multimodal multiparty interaction system that was presented at the London Science Museum as part of a robot festival,. We conclude the paper by discussing future developments, applications and opportunities of this technology.

    Studies on Using the SynFace Talking Head for the Hearing Impaired2009Inngår i: Proceedings of Fonetik'09: The XXIIth Swedish Phonetics Conference, June 10-12, 2009 / [ed] Peter Branderud, Hartmut Traunmüller, Stockholm: Stockholm University, 2009, s. 140-143Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    SynFace is a lip-synchronized talking agent which is optimized as a visual reading support for the hearing impaired. In this paper wepresent the large scale hearing impaired user studies carried out for three languages in the Hearing at Home project. The user tests focuson measuring the gain in Speech Reception Threshold in Noise and the effort scaling when using SynFace by hearing impaired people, where groups of hearing impaired subjects with different impairment levels from mild to severe and cochlear implants are tested. Preliminaryanalysis of the results does not show significant gain in SRT or in effort scaling. But looking at large cross-subject variability in both tests, it isclear that many subjects benefit from SynFace especially with speech with stereo babble.

    Lip Synchronization: from Phone Lattice to PCA Eigen-projections using Neural Networks2008Inngår i: INTERSPEECH 2008: 9TH ANNUAL CONFERENCE OF THE INTERNATIONAL SPEECH COMMUNICATION ASSOCIATION 2008, BAIXAS: ISCA-INST SPEECH COMMUNICATION ASSOC , 2008, s. 2016-2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Lip synchronization is the process of generating natural lip movements from a speech signal. In this work we address the lip-sync problem using an automatic phone recognizer that generates a phone lattice carrying posterior probabilities. The acoustic feature vector contains the posterior probabilities of all the phones over a time window centered at the current time point. Hence this representation characterizes the phone recognition output including the confusion patterns caused by its limited accuracy. A 3D face model with varying texture is computed by analyzing a video recording of the speaker using a 3D morphable model. Training a neural network using 30 000 data vectors from an audiovisual recording in Dutch resulted in a very good simulation of the face on independent data sets of the same or of a different speaker.

    Taming Mona Lisa: communicating gaze faithfully in 2D and 3D facial projections2012Inngår i: ACM Transactions on Interactive Intelligent Systems, ISSN 2160-6455, Vol. 1, nr 2, s. 25-, artikkel-id 11Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The perception of gaze plays a crucial role in human-human interaction. Gaze has been shown to matter for a number of aspects of communication and dialogue, especially for managing the flow of the dialogue and participant attention, for deictic referencing, and for the communication of attitude. When developing embodied conversational agents (ECAs) and talking heads, modeling and delivering accurate gaze targets is crucial. Traditionally, systems communicating through talking heads have been displayed to the human conversant using 2D displays, such as flat monitors. This approach introduces severe limitations for an accurate communication of gaze since 2D displays are associated with several powerful effects and illusions, most importantly the Mona Lisa gaze effect, where the gaze of the projected head appears to follow the observer regardless of viewing angle. We describe the Mona Lisa gaze effect and its consequences in the interaction loop, and propose a new approach for displaying talking heads using a 3D projection surface (a physical model of a human head) as an alternative to the traditional flat surface projection. We investigate and compare the accuracy of the perception of gaze direction and the Mona Lisa gaze effect in 2D and 3D projection surfaces in a five subject gaze perception experiment. The experiment confirms that a 3Dprojection surface completely eliminates the Mona Lisa gaze effect and delivers very accurate gaze direction that is independent of the observer's viewing angle. Based on the data collected in this experiment, we rephrase the formulation of the Mona Lisa gaze effect. The data, when reinterpreted, confirms the predictions of the new model for both 2D and 3D projection surfaces. Finally, we discuss the requirements on different spatially interactive systems in terms of gaze direction, and propose new applications and experiments for interaction in a human-ECA and a human-robot settings made possible by this technology.

    Analysis of gaze and speech patterns in three-party quiz game interaction2013Inngår i: Interspeech 2013, 2013, s. 1126-1130Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In order to understand and model the dynamics between interaction phenomena such as gaze and speech in face-to-face multiparty interaction between humans, we need large quantities of reliable, objective data of such interactions. To date, this type of data is in short supply. We present a data collection setup using automated, objective techniques in which we capture the gaze and speech patterns of triads deeply engaged in a high-stakes quiz game. The resulting corpus consists of five one-hour recordings, and is unique in that it makes use of three state-of-the-art gaze trackers (one per subject) in combination with a state-of-theart conical microphone array designed to capture roundtable meetings. Several video channels are also included. In this paper we present the obstacles we encountered and the possibilities afforded by a synchronised, reliable combination of large-scale multi-party speech and gaze data, and an overview of the first analyses of the data. Index Terms: multimodal corpus, multiparty dialogue, gaze patterns, multiparty gaze.

    Effects of 2D and 3D Displays on Turn-taking Behavior in Multiparty Human-Computer Dialog2011Inngår i: SemDial 2011: Proceedings of the 15th Workshop on the Semantics and Pragmatics of Dialogue / [ed] Ron Artstein, Mark Core, David DeVault, Kallirroi Georgila, Elsi Kaiser, Amanda Stent, Los Angeles, CA, 2011, s. 192-193Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The perception of gaze from an animated agenton a 2D display has been shown to suffer fromthe Mona Lisa effect, which means that exclusive mutual gaze cannot be established if there is more than one observer. In this study, we investigate this effect when it comes to turntaking control in a multi-party human-computerdialog setting, where a 2D display is compared to a 3D projection. The results show that the 2D setting results in longer response times andlower turn-taking accuracy.

    Perception of Gaze Direction for Situated Interaction2012Inngår i: Proceedings of the 4th Workshop on Eye Gaze in Intelligent Human Machine Interaction, Gaze-In 2012, ACM , 2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Accurate human perception of robots' gaze direction is crucial for the design of a natural and fluent situated multimodal face-to-face interaction between humans and machines. In this paper, we present an experiment targeted at quantifying the effects of different gaze cues synthesized using the Furhat back-projected robot head, on the accuracy of perceived spatial direction of gaze by humans using 18 test subjects. The study first quantifies the accuracy of the perceived gaze direction in a human-human setup, and compares that to the use of synthesized gaze movements in different conditions: viewing the robot eyes frontal or at a 45 degrees angle side view. We also study the effect of 3D gaze by controlling both eyes to indicate the depth of the focal point (vergence), the use of gaze or head pose, and the use of static or dynamic eyelids. The findings of the study are highly relevant to the design and control of robots and animated agents in situated face-to-face interaction.

    Turn-taking Control Using Gaze in Multiparty Human-Computer Dialogue: Effects of 2D and 3D Displays2011Inngår i: Proceedings of the International Conference on Audio-Visual Speech Processing 2011, Stockholm: KTH Royal Institute of Technology, 2011, s. 99-102Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In a previous experiment we found that the perception of gazefrom an animated agent on a two-dimensional display suffersfrom the Mona Lisa effect, which means that exclusive mutual gaze cannot be established if there is more than one observer. By using a three-dimensional projection surface, this effect can be eliminated. In this study, we investigate whether this difference also holds for the turn-taking behaviour of subjects interacting with the animated agent in a multi-party dialogue. We present a Wizard-of-Oz experiment where five subjects talk toan animated agent in a route direction dialogue. The results show that the subjects to some extent can infer the intended target of the agent’s questions, in spite of the Mona Lisa effect, but that the accuracy of gaze when it comes to selecting an addressee is still significantly lower in the 2D condition, ascompared to the 3D condition. The response time is also significantly longer in the 2D condition, indicating that the inference of intended gaze may require additional cognitive efforts.

    Lip-reading: Furhat audio visual intelligibility of a back projected animated face2012Inngår i: Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), Springer Berlin/Heidelberg, 2012, s. 196-203Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Back projecting a computer animated face, onto a three dimensional static physical model of a face, is a promising technology that is gaining ground as a solution to building situated, flexible and human-like robot heads. In this paper, we first briefly describe Furhat, a back projected robot head built for the purpose of multimodal multiparty human-machine interaction, and its benefits over virtual characters and robotic heads; and then motivate the need to investigating the contribution to speech intelligibility Furhat's face offers. We present an audio-visual speech intelligibility experiment, in which 10 subjects listened to short sentences with degraded speech signal. The experiment compares the gain in intelligibility between lip reading a face visualized on a 2D screen compared to a 3D back-projected face and from different viewing angles. The results show that the audio-visual speech intelligibility holds when the avatar is projected onto a static face model (in the case of Furhat), and even, rather surprisingly, exceeds it. This means that despite the movement limitations back projected animated face models bring about; their audio visual speech intelligibility is equal, or even higher, compared to the same models shown on flat displays. At the end of the paper we discuss several hypotheses on how to interpret the results, and motivate future investigations to better explore the characteristics of visual speech perception 3D projected faces.

    Multimodal Multiparty Social Interaction with the Furhat Head2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We will show in this demonstrator an advanced multimodal and multiparty spoken conversational system using Furhat, a robot head based on projected facial animation. Furhat is a human-like interface that utilizes facial animation for physical robot heads using back-projection. In the system, multimodality is enabled using speech and rich visual input signals such as multi-person real-time face tracking and microphone tracking. The demonstrator will showcase a system that is able to carry out social dialogue with multiple interlocutors simultaneously with rich output signals such as eye and head coordination, lips synchronized speech synthesis, and non-verbal facial gestures used to regulate fluent and expressive multiparty conversations.

    Visual Debugging of Dataflow Systems2017Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Big data processing has seen vast integration into the idea of data analysis in live streaming and batch environments. A plethora of tools have been developed to break down a problem into manageable tasks and to allocate both software and hardware resources in a distributed and fault tolerant manner. Apache Spark is one of the most well known platforms for large-scale cluster computation. In SICS Swedish ICT, Spark runs on top of an in-house developed solution. HopsWorks provides a graphical user interface to the Hops platform that aims to simplify the process of configuring a Hadoop environment and improving upon it. The user interface includes, among other capabilities, an array of tools for executing distributed applications such as Spark, TensorFlow, Flink with a variety of input and output sources, e.g. Kafka, HDFS files etc.

    Currently the available tools to monitor and instrument a stack that includes the aforementioned technologies come from both the corporate and open source world. The former is usually part of a bigger family of products running on proprietary code. In contrast, the latter offers a wider variety of choices with the most prominent ones lacking either the flexibility in exchange for a more generic approach or the ease of gaining meaningful insight except of the most experienced users.

    The contribution of this project is a visualization tool in the form of a web user interface, part of the Hops platform, for understanding, debugging and ultimately optimizing the resource allocation and performance of dataflow applications. These processes are based both on the abstraction provided by the dataflow programming paradigm and on systems concepts such as properties of data, how much variability in the data, computation, distribution, and other system wide resources.

    Mobile Ajax2008Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    This report describes a master thesis performed at SICS (Swedish Institute of Computer Science) and KTH (The Royal Institute of Technology) in Stockholm.

    Ajax stands for "Asynchronous JavaScript and XML" and it's not a programming language, but a suite of technologies used to develop web applications with more interactivity than the traditional web pages.

    Ajax applications can be adapted for mobile and constrained devices. This has been called Mobile Ajax. While the technique is the same, Mobile Ajax generally is considered to be a special case of Ajax, because it deals with problems specific to the mobile market.

    The purpose of this thesis has been to examine which possibilities and disadvantages has the Mobile Ajax from developers and users perspective. In addition we compare Mobile Ajax with Java Micro Edition (Java ME) and Flash Lite.

    This has been done through literature studies and development of a databased chat client (MAIM -Mobile Ajax Instant Messenger). The application sends and receives direct messages in real time between differently mobile devices. Then MAIM application has been compared with our own developed Java ME and Flash Lite chat clients.

    We have tested all three applications with different models of mobile devices and on different web browsers. The results have shown that mobile Ajax makes possible the creation of sophisticated and dynamic mobile web applications and is better than the classic web application model, but this requires that the mobile device has a modern and compatible web browser like Opera mobile.

    Optimal Cross-Layer Design for Energy Efficient D2D Sharing Systems2017Inngår i: IEEE Transactions on Wireless Communications, ISSN 1536-1276, E-ISSN 1558-2248, Vol. 16, nr 2, s. 839-855Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this paper, we propose a cross-layer design, which optimizes the energy efficiency of a potential future 5G spectrum-sharing environment, in two sharing scenarios. In the first scenario, underlying sharing is considered. We propose and minimize a modified energy per good bit (MEPG) metric, with respect to the spectrum sharing user's transmission power and media access frame length. The cellular users, legacy users, are protected by an outage probability constraint. To optimize the non-convex targeted problem, we utilize the generalized convexity theory and verify the problem's strictly pseudoconvex structure. We also derive analytical expressions of the optimal resources. In the second scenario, we minimize a generalized MEPG function while considering a probabilistic activity of cellular users and its impact on the MEPG performance of the spectrum sharing users. Finally, we derive the associated optimal resource allocation of this problem. Selected numerical results show the improvement of the proposed system compared with other systems.

    Power Enhancement in Piezoelectric Energy Harvesting2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Piezoelectric energy harvesting has been around for almost a decade to generate power from the ambient vibrations. Although the generated power is very small, but there are several ways to increase and enhance the generated power. This project presents different methods of optimizing the output power by changing the structural configuration of the energy harvesters, selection of piezoelectric material and circuit interface of these harvesters. To understand the different steps of the enhancement, the process of energy conversion by piezoelectric material has been first looked at.

    Different groups of piezoelectric material were studied to see what kind of materials have the ability of increasing the generated power. As mechanical configuration of the energy harvesters has a significant effect on the output voltage, their configuration such as Cantilever beam type, Cymbal type and Circular diaphragms has been described and compared. After the power generated in the piezoelectric crystal , the current is sent to through an interface circuit to get rectified and regulated. This circuit can be modified to increase the power as well. There are several types of circuits that can increase the output voltage significantly. Synchronized Switch Harvesting (SSH) techniques, Synchronous Electric Charge Extraction technique and voltage doubler are such examples. These techniques have been also studied and compared. Because of the outgrowing industry of piezoelectric energy harvesting in Medical field, their function and their progress has also been reviewed.

    A comparative study of hybrid artificial neural network models for one-day stock price prediction2015Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Prediction of stock prices is an important financial problem that is receiving increased attention in the field of artificial intelligence. Many different neural network and hybrid models for obtaining accurate prediction results have been proposed during the last few years in an attempt to outperform the traditional linear and nonlinear approaches.

    This study evaluates the performance of three different hybrid neural network models used for one-day stock close price prediction; a pre-processed evolutionary Levenberg-Marquardt neural network, Bayesian regularized artificial neural network and neural network with technical- and fractal analysis. It was also determined which of the three outperformed the others.

    The performance evaluation and comparison of the models are done using statistical error measures for accuracy; mean square error, symmetric mean absolute percentage error and point of change in direction.

    The results indicate good performance values for the Bayesian regularized artificial neural network, and varied performance for the others. Using the Friedman test, one model clearly is different in its performance relative to the others, probably the above mentioned model.

    The results for two of the models showed a large standard deviation of the error measurements which indicates that the results are not entirely reliable.

    Recurrent neural networks in electricity load forecasting2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    In this thesis two main studies are conducted to compare the predictive capabilities of feed-forward neural networks (FFNN) and long short-term memory networks (LSTM) in electricity load forecasting.

    The first study compares univariate networks using past electricity load, as well as multivariate networks using past electricity load and air temperature, in day-ahead load forecasting using varying lookback periods and sparsity of past observations. The second study compares FFNNs and LSTMs of different complexities (i.e. network sizes) when restrictions imposed by limitations of the real world are taken into consideration.

    No significant differences are found between the predictive performances of the two neural network approaches. However, adding air temperature as extra input to the LSTM is found to significantly decrease its performance. Furthermore, the predictive performance of the FFNN is found to significantly decrease as the network complexity grows, while the predictive performance of the LSTM is found to increase as the network complexity grows. All the findings considered, we do not find that there is enough evidence in favour of the LSTM in electricity load forecasting.

    Effect of error in CSI on the capacity of Rayleigh fading channels with QAM signalling and the design of robust signal constellations2007Inngår i: IET Communications, ISSN 1751-8628, E-ISSN 1751-8636, Vol. 1, nr 6, s. 1118-1125Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The effects of channel estimation errors on the channel capacity of a discrete time, discrete input, infinite output Rayleigh fading channel are investigated. The case of conventional modulation methods such as phase shift keying (PSK) and quatrature amplitude modulation (QAM) is investigated at first where it was observed that the capacity degrades rapidly with increasing channel estimation errors. The effect of error in the channel estimation is similar to the effect of higher noise in the channel that depends on the transmitted signal. A genetic algorithm is used to optimise the signal constellation in order to maximise the capacity for a given finite number of signal points. The aim of trying to maximise the capacity is to estimate the remaining gap in performance between a traditional modulation scheme such as QAM and the best possible constellation that is optimised for the channel. The constellations obtained from the genetic algorithm are, in general, not directly implementable. A method to design practical robust signal constellations that overcome the effect of channel state information (CSI) error is presented. The robust signal constellations obtained show a performance that is very close to the optimal constellations. In this work, the probability distribution of the error in CSI is assumed to be known.

    Utvärdering utifrån ett mjukvaruutveckling perspektiv av ramverk för SharePoint2017Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Inom ett företag eller en organisation finns det stor nytta av intranät som ett arbetsverktyg för att kunna dela information. Ett välfungerat intranät bidrar till ett bättre informationsflöde och ett effektivare samarbete. SharePoint är en plattform för intranät med interaktiva funktioner. Omnia är ett ramverk anpassad för Microsofts SharePoint 2013.I detta arbete undersöks hur Omnia fungerar som ett ramverk och vad produkten lämpar sig för. Omnia ramverket utvärderades noggrant och en oberoende bedömning utfördes under examensarbetet. Utvärderingen var baserad på vetenskapliga undersökningar som byggde på den kvalitativa och kvantitativa forskningsmetodiken. Utvärderingens huvudområden baserades på systemets prestanda, skalbarhet, arkitektur och funktionalitet. En testprototyp utvecklades under arbetets gång genom Omnia i from av en webbaserad applikation.Ramverket Omnia var lämplig för utveckling av interaktiva webbaserade applikationer för intranät i SharePoint. Dock saknade den färdig dokumentation/API, vilket gjorde utvecklingsprocessen mer avancerad. Lösningsarkitekturen för systemet uppfyllde kraven för skalbara system, eftersom den baserades på lagerarkitektur. Systemet hade även bra prestanda, dock försämrades den efter att antalet användare översteg ettusen. Funktionaliteten testades med hjälp av två olika tester, vilket visade att produkten är lämplig för att användas i intranät.

    Knowledge Extraction by Visual Data Mining of Metadata in Site PlanningManuskript (Annet vitenskapelig)
    Abstract [en]

    The paper describes a tool designed within the first stage of the European project INVISIP in order to explore geographical metadata in the site planning process. A visual data mining approach is applied to a database of geographical metadata to help the user find an optimal subset of the existing geographical datasets for his particular planning task. It allows the user to perform both confirmative and explorative analysis. The approach is implemented in the Visual Data Mining tool, which integrates different types of visualisations with various interaction functionalities. It includes the interactive communication with the user and the brushing and linking process between different visualisations. The paper also presents an example of an application on a test metadatabase which was created for this purpose.

    Abstract [en]

    Swedish municipalities' websites contain vast amounts of information that caters to a broad audience. For users to be able to access this information, it is important that the website is accessible, to everyone. 74 percent of people with disabilities states in a survey conducted by the Swedish Agency for Participation (2015a) that they use the internet to make contact with local municipalities, but simultaneously more than 1 out of 10 experiences difficulties associated with the use of computers and the Internet, according to Statistics Sweden (2014). The purpose of this study was to identify how Swedish municipalities are working to make their website available for people with disabilities. The study also examined what municipalities should do to make available their website and what difficulties are in the process of making a municipal website available.

     

    In working with this survey people who have insights into the subject and seven community representatives were interviewed. To collect quantitative data a questionnaire survey answered by 208 of Sweden's 290 municipalities was conducted.

     

    The study resulted in a survey of how Swedish municipalities work with web accessibility, a study of what actions the municipalities should take and also problematic factors in the process to become accessible. Today, many municipalities are investing in the development of new websites but there are four main factors that affect their work. These factors are lack of knowledge, lack of resources, organizational characteristics, such as unclear division of responsibility and decentralized organizations, and the lack of distinct requirements. The survey also shows that there are significant differences between the small and big municipalities regarding their accessibility initiative.

    Svenska företags användning av sociala medier som marknadsföringsverktyg – En observation över vilka aktiviteter som lämpar sig att bedriva på sociala medier idag.2012Independent thesis Advanced level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    Today companies increasingly use social media as a part of their marketing strategy. Most companies have discovered the value of using social media and are today registered on multiple platforms, but what kind of content is published by the companies on these platforms? The different platforms are constructed in different ways and around different attributes; are there therefore certain types of content that are more suitable to publish on a certain platform?

    This thesis addresses and answers the following main question: What different kinds of activities are suitable for Swedish companies to conduct on different social media platforms? The question have been answered by the theory that this thesis processed, by an observation of how Swedish companies are using social media today and by interviews conducted with one company and one PR agency. Based on a discussion of the results of the thesis it appears that it is not possible to draw guidelines for what kind of posts that is more or less suitable to publish on the different platforms. What instead seems to determine which platform that the companies should use is the depth of the information they would like to publish. For all platforms it is shown that the focus of the companies should be interaction with users of the platforms. They should also publish posts frequently on the platforms they are using, but not with an excessive frequency as this tends to disturb the users.

    Designing the Publikvitto, a system to make government expenditure tangible2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Air transportation is essential to our society. It enables global trading, brings people together, and lets travelers explore distant parts of the world. However, flying is a highly unsustainable behavior and accounts for roughly 2% of all carbon emissions; with industry and research forecasting constant growth in the coming years. The economic benefits rhetoric often prevails over the environmental costs, though; motivating governments to give incentives to airports and airlines. The Swedish Government, despite its green goals and pro-sustainability actions, is no exception, and both municipal and federal funds support the air route network.

    This thesis reports on the development of the Publikvitto, a system designed to help citizen make sense of the government's incentives to the flying industry. The process is based on research through design and inspired by reflective practices. The primary outcome are insights into the relationship between designer, social issues, and government's actions; and how these elements can be approached in order to design artifacts that motivate people to engage in political discussions.

    Abstract [en]

    As new forms of propaganda and information control spread across the internet, the need for novel ways of identifying them increases as well. One increasingly popular method of spreading false messages on microblogs like Twitter is to disseminate them from seemingly ordinary, but centrally controlled and coordinated user accounts – sockpuppets. In this paper we examine a number of potential methods for identifying these by way of applying plagiarism detection algorithms for text, and evaluate their performance against this type of threat. We identify one type of algorithm in particular – that using vector space modeling of text – as particularly useful in this regard.

    Anpassning av en interaktiv skrivtavla till svenska klassrum.2012Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    During recent years interactive writing boards (digital whiteboards) have become very popular in classrooms. Many schools choose to renovate their classrooms and are then considering the possibility of equipping the classrooms with a computer, projector and an interactive writing board. The interactive writing board can be used like a regular whiteboard, but offers new possibilities such as playing back recorded media files. There are a many different applications available since the interactive whiteboard uses a normal computer. The lessons can be saved on the computer and the lessons can be repeated with the students. The lesson files can easily be distributed via e-mail or web pages.

    This report show encountered limitations and possibilities to improve the software for the interactive writing board ePLUS. The study is based on a literature study and teacher interviews. A prototype software was also developed which was then evaluated using further interviews.

    The results in this report show that the large number of different programs confuses the users who easily mix up the different features in the programs. Remarkably few of the interviewed teachers actually use the digital pen actively in their teaching. This is probably a result of poor education or lack of interest. In order to improve the use of ePLUS in the schools, the software has to be very flexible and fit both basic and advanced users. This could be obtained by introducing a “difficulty setting” which can be set by the user. This setting could control the number of visible buttons and available features. Many improvements can be made, but there is also a limit in how many specialized features that can actually be implemented. Many of the interviewed teachers requested special features or premade lessons adapted to their teaching habits. It is however difficult to implement many special features without affecting the complexity of the software.

    The research was primarily aimed at software issues, but it also revealed that the classrooms in many schools need to be adapted to the new technology in order to utilize it better. As an example is it sometimes difficult to control the room lighting. The position of the projector screen is also sometimes hindering the education. It is very important that the teachers get sufficient education in the software, in order for them to feel comfortable using the writing board.

    Provinsgenerering med postprocess2014Independent thesis Advanced level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    This bachelor's thesis is a part of a larger project carried out at Paradox Interactive. The project aims to improve a map generator for the strategy game Europa Universalis IV. This work addresses the creation and implementation of a province generator that divides a pregenerated landscape in provinces. The provinces in the game are the regions on the game map that the game mechanics are based upon. The improvements that are expected of the new province generator includes the following properties:

    • The provinces that are created have more logically placed boundaries that are affected by the structure of the landscape.

    • The program gives the user more control over how the end result should look like by letting the user set the values of input parameters.

    • The execution should not exceed an approximate time limit. This time limit is set by Paradox Interactive.

    The work began with research on the topics map creation and map division to give enough knowledge to plan the implementation of the program. The programming language that is used is Java. The implementation of the program is based on many well-known algorithms in which the most remarkable one is Fortune's algorithm which performs the main task of the provincial division of the program, the creation of Voronoi diagrams. The Voronoi diagrams are used to divide the map into regions which by using a post-process results in the creation of the provinces.

    Other well-known algorithms and methods used or addressed in this report include the Lloyd relaxation, Bresenham's line algorithm, Scan Line Flood Fill, Delaunay triangulation and Bowyer-Watson's algorithm. The result of this work is a Java application that can load a map file containing information of a landscape structure and create a division of provinces with provincial boundaries that depend on the structure of the landscape. The results of the provincial division may be controlled by a number of user defined parameters. The program could not be fully calibrated during the time of the project because the landscape generator was not ready in time to be able to provide a map of a generated landscape. The generated provinces can be saved as an image file on the hard disk.

    Utvärdering av ett elektroniskt journalsystem för veterinärer: Identifiering av lämpliga lösningar på ett problem beträffande användbarhet2015Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Mål: Enligt svensk lag måste veterinärer dokumentera information om alla patientbesök. Patientjournaler är användbara för att samla uppgifter om hälsotillståndet hos de djur som behandlats. Syftet med denna studie var att utvärdera och upptäcka användbarhetsproblem i ett befintligt elektroniskt patientjournalsystem som används av veterinärer.

    Metoder: Fyra olika metoder användes för att uppnå målen med studien under en tidsperiod av 14 veckor. Första metoden var fältstudier och observationer som genomfördes på två olika kliniker nära Stockholmsområdet. Tänka-högt-metoden användes för att utvärdera fyra tester, representerande användarflöden, i systemet för att lokalisera användbarhetsfrågor. Fem personer deltog i testet, tre läkarsekreterare och två personer med en teknisk bakgrund. Under en och en halv vecka, genomfördes den heuristiska genomgången bestående av 90 olika tester. Slutligen skickades en enkät bestående av 14 frågor ut till alla veterinärer som för närvarande använder det elektroniska patientjournalsystemet.

    Resultat: Fältstudierna och observationerna resulterade i en storyboard som representerar en visualiserad bild av veterinärernas arbetssituation. Testerna med tänka-högt-metoden synliggjorde de problem deltagarna upptäckte. Efter den heuristiska genomgången hittades 27 buggar och 7 användbarhetsproblem. Totalt hade enkäten en räckvidd av cirka 340 veterinärer och 120 svarade, en svarskvot på 35 %. En sammanfattning av svaren visade att det fanns problem med alltför många klick för att slutföra en uppgift. Användare tyckte det var svårt att få en överblick över systemet och att det var tidskrävande att slutföra sina arbetsuppgifter. Lösningar på problem visualiseras genom pappersprototyper.

    Konsumenters syn på QR-koder i marknadsföring.2012Independent thesis Advanced level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    Nowdays QR codes appears on everything from newspaper ads to food products. Using a smartphone and a QR reader consumers are able to scan these codes. The purpose of this study is to understand how well companies reach the consumers by using QR codes in their marketing. The study discuss which expectations consumers have on different ads and if these expecations are fulfilled.

    The result of this study indicates that consumers are interested in scanning the QR codes. QR codes have a great chance in succeeding as a good marketing strategy. However it requires some changes in both the behavior of the consumers and companies. The companies have certain factors they need to improve for the consumers to take the step and scan the QR codes. Clear information about what to expect from the QR code was one of the factors the participants in the interviews valued most.

    Wearables and the potential of Google Glass2015Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    The Mobile Life (TML) is a company with great passion for mobile devices that has set its primary focus on developing tailor-made mobile applications. Some of their bigger clients consist of airlines where TML designs, develops and delivers applications, in which travelers who travel with the airline can use to browse through, reserve and book flights.

    Wearable Technology is being more and more embraced as the future big addition to the ecosystem of mobile devices and exploring what some of the more prominent wearables have to offer is very much in the interest of aspiring companies like TML. To understand more in-depth what it means to develop applications for devices that might suffer from vast limitations in regards to interaction and feedback, we would first investigate what coming wearables could be recognized as prominent. The wearables that we concluded as suitable to investigate closer were Google Glass, Android Wear and various smartwatches. Out of these, Google Glass was the device chosen to act as our platform when exploring the potential of a wearable. A suitable way of understanding the possibilities and limitations of user interaction for Google Glass was to develop our own flight booking application for Glass.

    The realization we got was that there are various aspects of Glass that limits the kind of applications that can be made for it. The two primary things are the limits of the hardware and the fact that user interaction has taken a step back. From the graphical directmanipulation interaction that we nowadays are so used to in smartphones, to a simple menu system with limitations to how much the user can interact and how much feedback the program can show the user.

    Architectures and protocols for fast identification in large-scale RFID systems2014Inngår i: ISCCSP 2014 - 2014 6th International Symposium on Communications, Control and Signal Processing, Proceedings, 2014, s. 243-246Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Passive tags based on backscattered signals yield low energy consumption for large-scale applications of RFIDs. In this paper, system architectures and protocol enhancements for fast identifications in ISO/IEC 18000-6C systems that integrate UWB technology are investigated. The anti-collision protocol is studied by considering various tag populations. A novel algorithm is proposed to adapt the UHF air interface parameters with the use of UWB ranging information. The results show that the proposed algorithm yields up to 25% potential performance improvement compared to the ISO/IEC 18000-6C standard.

    Being and mixing: designing interactive soundscapes2006Inngår i: Proceedings of the 4th Nordic conference on Human-computer interaction: changing roles, 2006, s. 252-261Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper describes a study of the auditory environment in a chemical factory, and how a group of process operators ascribe meaning to a selection of sound clips from their daily work environment. We argue for a design-oriented phenomenological approach to soundscape studies, and suggest an approach based on an exploration of how already occurring sounds are used. This knowledge will be used to inform the design of new useful auditory environments. Our study shows that the richness of the auditory environment is a crucial aspect of the distributed work environment. An important part of the design process is the operator’s contribution to the concepts suggested. From design workshops several design concepts aiming to explore and test different approaches for making sound affordances available have been developed. This has led us to a new understanding of how interactive soundscapes enable distributed awareness – what we refer to as ’Being and Mixing’.

    Performance, Processing and Perception of Communicative Motion for Avatars and Agents2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Artificial agents and avatars are designed with a large variety of face and body configurations. Some of these (such as virtual characters in films) may be highly realistic and human-like, while others (such as social robots) have considerably more limited expressive means. In both cases, human motion serves as the model and inspiration for the non-verbal behavior displayed. This thesis focuses on increasing the expressive capacities of artificial agents and avatars using two main strategies: 1) improving the automatic capturing of the most communicative areas for human communication, namely the face and the fingers, and 2) increasing communication clarity by proposing novel ways of eliciting clear and readable non-verbal behavior.

    The first part of the thesis covers automatic methods for capturing and processing motion data. In paper A, we propose a novel dual sensor method for capturing hands and fingers using optical motion capture in combination with low-cost instrumented gloves. The approach circumvents the main problems with marker-based systems and glove-based systems, and it is demonstrated and evaluated on a key-word signing avatar. In paper B, we propose a robust method for automatic labeling of sparse, non-rigid motion capture marker sets, and we evaluate it on a variety of marker configurations for finger and facial capture. In paper C, we propose an automatic method for annotating hand gestures using Hierarchical Hidden Markov Models (HHMMs).

    The second part of the thesis covers studies on creating and evaluating multimodal databases with clear and exaggerated motion. The main idea is that this type of motion is appropriate for agents under certain communicative situations (such as noisy environments) or for agents with reduced expressive degrees of freedom (such as humanoid robots). In paper D, we record motion capture data for a virtual talking head with variable articulation style (normal-to-over articulated). In paper E, we use techniques from mime acting to generate clear non-verbal expressions custom tailored for three agent embodiments (face-and-body, face-only and body-only).

    Animated Lombard speech: Motion capture, facial animation and visual intelligibility of speech produced in adverse conditions2014Inngår i: Computer speech & language (Print), ISSN 0885-2308, E-ISSN 1095-8363, Vol. 28, nr 2, s. 607-618Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this paper we study the production and perception of speech in diverse conditions for the purposes of accurate, flexible and highly intelligible talking face animation. We recorded audio, video and facial motion capture data of a talker uttering a,set of 180 short sentences, under three conditions: normal speech (in quiet), Lombard speech (in noise), and whispering. We then produced an animated 3D avatar with similar shape and appearance as the original talker and used an error minimization procedure to drive the animated version of the talker in a way that matched the original performance as closely as possible. In a perceptual intelligibility study with degraded audio we then compared the animated talker against the real talker and the audio alone, in terms of audio-visual word recognition rate across the three different production conditions. We found that the visual intelligibility of the animated talker was on par with the real talker for the Lombard and whisper conditions. In addition we created two incongruent conditions where normal speech audio was paired with animated Lombard speech or whispering. When compared to the congruent normal speech condition, Lombard animation yields a significant increase in intelligibility, despite the AV-incongruence. In a separate evaluation, we gathered subjective opinions on the different animations, and found that some degree of incongruence was generally accepted.

    Towards Fully Automated Motion Capture of Signs -- Development and Evaluation of a Key Word Signing Avatar2015Inngår i: ACM Transactions on Accessible Computing, ISSN 1936-7228, Vol. 7, nr 2, s. 7:1-7:17Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Motion capture of signs provides unique challenges in the field of multimodal data collection. The dense packaging of visual information requires high fidelity and high bandwidth of the captured data. Even though marker-based optical motion capture provides many desirable features such as high accuracy, global fitting, and the ability to record body and face simultaneously, it is not widely used to record finger motion, especially not for articulated and syntactic motion such as signs. Instead, most signing avatar projects use costly instrumented gloves, which require long calibration procedures. In this article, we evaluate the data quality obtained from optical motion capture of isolated signs from Swedish sign language with a large number of low-cost cameras. We also present a novel dual-sensor approach to combine the data with low-cost, five-sensor instrumented gloves to provide a recording method with low manual postprocessing. Finally, we evaluate the collected data and the dual-sensor approach as transferred to a highly stylized avatar. The application of the avatar is a game-based environment for training Key Word Signing (KWS) as augmented and alternative communication (AAC), intended for children with communication disabilities.

    Aspects of co-occurring syllables and head nods in spontaneous dialogue2013Inngår i: Proceedings of 12th International Conference on Auditory-Visual Speech Processing (AVSP2013), 2013, s. 169-172Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper reports on the extraction and analysis of head nods taken from motion capture data of spontaneous dialogue in Swedish. The head nods were extracted automatically and then manually classified in terms of gestures having a beat function or multifunctional gestures. Prosodic features were extracted from syllables co-occurring with the beat gestures. While the peak rotation of the nod is on average aligned with the stressed syllable, the results show considerable variation in fine temporal synchronization. The syllables co-occurring with the gestures generally show greater intensity, higher F0, and greater F0 range when compared to the mean across the entire dialogue. A functional analysis shows that the majority of the syllables belong to words bearing a focal accent.

    Extracting and analyzing head movements accompanying spontaneous dialogue2013Inngår i: Conference Proceedings TiGeR 2013: Tilburg Gesture Research Meeting, 2013Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper reports on a method developed for extracting and analyzing head gestures taken from motion capture data of spontaneous dialogue in Swedish. Candidate head gestures with beat function were extracted automatically and then manually classified using a 3D player which displays timesynced audio and 3D point data of the motion capture markers together with animated characters. Prosodic features were extracted from syllables co-occurring with a subset of the classified gestures. The beat gestures show considerable variation in temporal synchronization with the syllables, while the syllables generally show greater intensity, higher F0, and greater F0 range when compared to the mean across the entire dialogue. Additional features for further analysis and automatic classification of the head gestures are discussed.
