    Instagram och ekologisk hållbarhet: Hur påverkas användaren, ur ett miljöperspektiv, av ett flöde på Instagram?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Instagram is a social network that is very popular in Sweden. On Instagram, users take part of information in the form of images from accounts they have chosen to follow. The dissemination of information regarding climate change needs to be more effective. People's environmental degradation habits are a problem and need to be changed, but rooted behavior patterns can be difficult to break. The public needs a nudge in the right direction to live more climate-smart and to make more environmentally-friendly choices.

    The aim of the study is to, in a qualitative way, investigate how a feed on Instagram, can affect university students with a focus on climate change. The research question which the paper is based on is; How is the user affected, from an environmental perspective, by a feed on Instagram?

    The approach to investigate this meant that the participants used a modified Instagram account, the methods used are diary and individual semi-structured interviews. Patterns in the collected material from the diaries and interviews are structured under different themes and the result shows that the participants of the study have been affected in different ways. They have learned new things, acted on tips and recipes, shopped second hand, followed accounts that spread information about the environment from their own Instagram account, and had the climate situation more frequent in their thoughts. All these types of actions have in common that they are no big life adjustments, but rather simpler actions that are easy to apply in everyday life. More complicated actions, like growing their own herbs, raised an interest and the action was not performed. The discussion addresses the reasons for the different ways in which the participants have been affected and ties in with theories of social influence and nudging.

    Designing for sustainable grocery shopping: A conceptual design to encourage sustainable shopping2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Climate change is one of the biggest issues that the world faces today, and one of the biggest contributors to climate change are groceries. This paper aims at using digital artefacts to create a product or design that will encourage the user to shop more environmentally friendly. To achieve this, I have tried to identify the major hindrances today that grocery shoppers are faced with through the user centered method Contextual Inquiry.  I have then presented the results from the inquiry to students at KTH Royal Institute of Technology during workshops. During these workshops, the students have conceptualized ideas and designs for different solutions. Based on their results, I have created a prototype design that I call the SmartCart. This cart consists of a regular shopping cart with a screen similar to an iPad attached to the handlebars. This screen then delivers easily apprehensible information about different grocery products environmental impact in real time. The design has not been tested in a live environment, but initial testing indicates that a live application could give satisfying results in lowering the sales of grocery products with a high environmental impact, while the design also could simultaneously improve the shopping experience for the customers in the grocery store.

    Real-time labeling of non-rigid motion capture marker sets2017In: Computers & graphics, ISSN 0097-8493, E-ISSN 1873-7684, Vol. 69, no Supplement C, p. 59-67Article in journal (Refereed)
    Abstract [en]

    Passive optical motion capture is one of the predominant technologies for capturing high fidelity human motion, and is a workhorse in a large number of areas such as bio-mechanics, film and video games. While most state-of-the-art systems can automatically identify and track markers on the larger parts of the human body, the markers attached to the fingers and face provide unique challenges and usually require extensive manual cleanup. In this work we present a robust online method for identification and tracking of passive motion capture markers attached to non-rigid structures. The method is especially suited for large capture volumes and sparse marker sets. Once trained, our system can automatically initialize and track the markers, and the subject may exit and enter the capture volume at will. By using multiple assignment hypotheses and soft decisions, it can robustly recover from a difficult situation with many simultaneous occlusions and false observations (ghost markers). In three experiments, we evaluate the method for labeling a variety of marker configurations for finger and facial capture. We also compare the results with two of the most widely used motion capture platforms: Motion Analysis Cortex and Vicon Blade. The results show that our method is better at attaining correct marker labels and is especially beneficial for real-time applications.

    Rapid Serial Visual Presentation påmoderna mobiltelefoner2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is a comparative study of Rapid Serial Visual Presentation (RSVP) which is a

    dynamic method of presenting text.

    The aim of the study was to investigate how to improve the user friendlyness of RSVP for

    today's mobile phones and technology. To fulfill the purpose, the aspects of the method which

    could be improved was investigated and then implemented in a prototype. The prototype was

    tested in an experimental study after which the result was analyzed and compared with previous

    studies of RSVP.

    The new features that were implemented in this study showed no significant improvements in

    usability compared with previous studies, but proved to be more user-friendly in comparison

    with normal spatial reading.

    Twitter and Choreography- A Sucessful Combination?2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    One of the most common social media platforms of today is Twitter, an open

    community where content easily could be spread by sharing so called tweets and

    where the relationship between users is not constrained by accepting the other user.

    This report discusses the complexity in merging social media and dance by studying a

    project which used crowdsourcing through Twitter to collect choreographic ideas for

    a new ballet piece.

    In order to examine Twitter as a tool in a creative process, a questionnaire was sent to

    Twitter users and email interviews were held with those responsible for the project of

    study. The questionnaire showed that most of the Twitter users enjoyed creating and

    being part of a creative process. However, some of those with an occupation within

    the dance world voiced concerns about untrained people creating choreography.

    From the interviews it was found that a lot of thought had to be put into the structure

    of the project and that the project’s main motivator was to inspire and create with the

    help of people around the world.

    It was found in the research that Twitter is a suiting platform for a crowdsourced

    project since a large and varying group of participants is reached. Twitter allows for

    the Twitter users to participate regardless of location or occupation as well as

    bringing good publicity to the dance world.

    Placeringen av grafiska komponenter och dess påverkan på upplevt förtroende2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As e-commerce increases, customers’ buying habits are affected. This has in turn led to changed sales behavior for companies. Building trust towards customers is fundamental, as increased credibility not only eliminates the feeling of uncertainty but also contributes to an increased purchase intent. In order to build trust, it is fundamental to understand the importance of the website’s quality and design. In this paper, we look more closely at the product page, as we believe that it is one of the most important pages in an online store. The purpose of this essay is to contribute to increased knowledge on how the layout and content shaping increases or decreases user trust on an e-commerce platform. To be able to determine whether the placement of graphic components such as product title, product price, purchase button and navigation menu are of importance, we ask the question: Does the placement of graphic components on an online web shop affect user trust? The concept of trust is defined on the basis of initial trust, where a potential customer assesses the credibility based on superficial factors. When the customer is willing to rely on and carry out a purchase in an online store, they are thereby willing to take risks. To be able to answer this, a survey was conducted with 27 participants. In the survey, the participants then ranked prototypes, in which the placement of the graphic components varied. Participants ranked the prototypes according to both trust and confidence due to the risk of interpretation differences of the concept of trust. The results showed, despite the small number of participants, that the placement of graphical components likely has an effect on perceived trust.

    Användning av koldioxidbudgetar för att motivera minskning av koldioxidutsläpp2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The problem of rising temperatures and climate change is of great importance to all life. It has been made a global target by the UN and 194 countries has signed the Paris agreement which states a goal of keeping average global temperature raises two degrees below pre-industrial temperatures. Despite this, it is not clear what needs to be done. One thing for sure is that greenhouse gas emissions and ways to lessen them must be communicated in a concrete way in order to influence people and help fight climate change. This study explored how carbon budgets could be a tool for making greenhouse gas emissions less of an abstract concept. The study also examined how the implementation intentions-model could be used for increasing motivation in implementing behaviours in order to motivate reducing emissions of students. The focus of the study was to motivate participants to decrease consumption of aerial transportation and meat as these were ruled as important sources of emission for students.

    The study showed statistically significant results of whether these methods can be used in influencing participants behaviours.

    Låter du andra styra din identitet på Facebook?2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Social Networking Sites (SNS) are growing tremendously, both in terms of number of users and the time spent using social media and SNS. Facebook is the SNS with the most users in the world, and in Sweden 82% of the population in the ages 16 and 25 years visit the site daily. Social media have great impact on people’s lives and also impact the way young people form their identity.

    In this paper we have conducted a number of interviews to answer the question “What feeling are raised among Facebook users between 20-25 years in Sweden when someone else affects their profile through timeline posts and tags?”.

    The study shows that the feelings differs between the participants. The majority were positive to including friends in the social identity on Facebook. However, they also wanted to stay anonymous to keep control of one's identity presented online.

    Exploring affordances of tangible user interfaces for interactive lighting2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This paper explores interaction with lighting through a tangible user interface (TUI). In a TUI the physical object and space around it are part of the interface. A subset of tangible interaction called spatial interaction is the main focus of this paper. Spatial interaction refers to translation, rotation or location of objects or people within a space. The aim of this paper is to explore the relation between spatial inputs and lighting outputs based on different design properties.

    A user test is set up to explore the effect that design properties of a TUI have on the lighting output that participants map to spatial inputs. The results of the conducted user test indicate that communicating affordances to the user is an important factor when designing couplings between spatial inputs and lighting outputs. The results further show that the shape of the interface plays a central role in communicating those affordances and that the overlap of input and output space of the interface improves the clarity of the coupling.

    Media och Multitasking: En studie om utbildningspodcast och träning2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Since the evolution of new media technology together with a continuously more connected and stressed world, multitasking has become more common. Previous research shows that 90 percent of the population multitask at least once a day. However, it also shows that multitasking leads to stress and impaired performance in the activities you work with, especially learning activities. With reason in research, that shows that training enhances several functionalities in the brain connected with learning, an experiment study with 14 participants was conducted to examine how learning is affected during running.

    The participants in this study were students at the degree program in media technology at the Royal Institute of Technology, Sweden. The study used an experimental method with a control group and an experiment group; the control group sitting while listening to the podcast and the experiment group running while listening. The study shows that the difference in learning, from podcast, between the participants in the control group and the participators in the experiment group was modest. The results also indicate a small advantage for the control group, but it was not large enough to draw the conclusion that running affected the learning negatively. We instead assesses it as likely that the result is a consequence of a combination of multitasking affecting learning negatively, while training affecting it positively.

    DRM – Intrusion or Solution?2005In: Innovation and the knowledge economy / [ed] Cunningham, P., Cunningham, M., Amsterdam: IOS Press, 2005, p. 925-933Conference paper (Refereed)
    Abstract [en]

    DRM could be the solution to the content industry’s P2P dilemma, but content owners’ desire to monitor and control the consumer’s use of content can be perceived as an intrusion of privacy. High control makes consumers less active and low control invites them to experiment and to gain experience. Digital music files can easily be spread. Therefore legal services prefer keeping control over the music. This study reveals that consumers are one step ahead of the content industry, finding ways to circumvent protection and laws, and that the music industry is awaiting the "right" DRM business model. Online Music sellers basically rely on B2C DRM business models, but attempts have been made with C2C models, using consumers as distributors, and ISP models, where ISPs pay to collecting societies for all file trans-fers of copyrighted material in their networks. Future models include licensing mod-els, micro models, and no copyright at all.

    Life tracking och träningsmotivationvia smartphone2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Logging of everyday tasks such as fitness training is referred to as lifetracking.

    Since the 1980’s, obesity among Swedish 16-29 year-olds has doubled, because of

    poor eating habits and lack of physical activit. Today, most people in this agegroup

    have access to a smartphone of their own, and also considerable experience

    of using such devices. A smartphone enables lifetracking, which can be exploited

    to reduce the risk for obesity, through the use of motivational training

    applications.

    The purpose of the present investigation was to examine motivation levels of

    already active people by applying

    motivational theory. We have linked the

    characteristics of four selected

    lifetracking-aids to determine which of their

    characteristics are most effective in providing positive motivation for exercise.

    Twenty participants used the aids during a three-week period, and their patterns of

    usage were recorded and analyzed.

    The results show that logging of training is an effective way of increasing

    motivation. User opinions and changes in motivation also formed the basis for a

    training application prototype.

    SOUND FOREST/LJUDSKOGEN: A LARGE-SCALE STRING-BASED INTERACTIVE MUSICAL INSTRUMENT2016In: Sound and Music Computing 2016, SMC Sound&Music Computing NETWORK , 2016, p. 79-84Conference paper (Refereed)
    Abstract [en]

     In this paper we present a string-based, interactive, largescale installation for a new museum dedicated to performing arts, Scenkonstmuseet, which will be inaugurated in 2017 in Stockholm, Sweden. The installation will occupy an entire room that measures 10x5 meters. We aim to create a digital musical instrument (DMI) that facilitates intuitive musical interaction, thereby enabling visitors to quickly start creating music either alone or together. The interface should be able to serve as a pedagogical tool; visitors should be able to learn about concepts related to music and music making by interacting with the DMI. Since the lifespan of the installation will be approximately five years, one main concern is to create an experience that will encourage visitors to return to the museum for continued instrument exploration. In other words, the DMI should be designed to facilitate long-term engagement. Finally, an important aspect in the design of the installation is that the DMI should be accessible and provide a rich experience for all museum visitors, regardless of age or abilities.

    Key Tension Points and Design Guidelines for GDPR Compliance: Designing for a News Service Application2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Digitization poses a threat to the fundamental rights of individuals' personal sphere. This is due to deficiency within the current bylaws to protect data subjects' privacy and the lack of social codes for handling privacy in the virtual space. Colossal amount of implicit data processing, takes away data subject's control over their personal data. In order to protect data subjects from this treacherous relationship, between stakeholders and data subjects, the European Union has issued the new General Data Protection Regulation that was enforced in May 2018. Companies operating within EU thereby face substantive legislative reform in data protection. However, there are no current guidelines for how to acclimatize to the new regulation of processing personal data, especially for subsidiary companies. This study therefore addresses this gap by detailing the design process of attaining GDPR compliance for a subsidiary news service application. From this process, nine key tension points were identified and reformulated into five design guidelines more broadly applicable to design for privacy. In addition, two boundary objects and a transparency-layer strategy were formulated.

    This bachelor’s thesis investigates how students can improve their habits of studying by way of

    lifetracking in mobile applications. The lifetracking application being used in this study goes by the name

    of Lift. To maximize its potential for success it is beneficial if the motivation to change comes from the

    student in question, if the student has an interest for testing new technology and if the student is curious

    and willing to try out unknown techniques. If one intends to use Lift in its studies one should choose

    habits which hold value and which are repeatable for a longer period of time. This will contribute to a

    greater chance of success.

    last decades integrated concepts from HCI (Human Computer Interaction) in the development

    of their products. Many of these products were created for the use of amateur musicians who are

    not educated in the subject of music theory. Therefor the designers found it necessary to

    prioritize simplicity of use in the development of their products. However, the use of these

    products can invoke dimensional limitations to the user’s freedom of music creation

    .

    The aim of the study was to design and evaluate an interface on a music keyboard which

    encourages the user to make better use of her own creativity while playing music. Visualizing

    music scales on keyboard is an attempt, by the authors of this paper, to combine the simplicity

    of several modern music equipment with less limitations of the musical structure similar to that

    of conventional music instruments.

    Published and accepted literature tangential to the topic of this paper has been studied and

    comprehensive reviews of different modern musical interfaces have been made. A user test has

    been developed based on the knowledge gained from these studies. Additionally, a form has

    been designed in which the test subjects were prompted to express their subjective views on the

    interface and its influence.

    The results from the tests indicate that fewer tonal errors, as well as fewer repetitions of parts of

    the melody, were made using a keyboard with visualized music scale. On the other hand, the

    results also indicate a tendency of the user skipping tones, which was generally more frequent

    using the mentioned interface. These missing tones had, however, minor impact on the

    subjective result. The final conclusion of the study is that an interface for the visualization of

    music scales on keyboard generates more positive than negative effects on amateur musicians’

    music performance. Additionally, the negative effects can be neglected in comparison to the

    positive effects of using the interface.

    The Impact of Navigation on Survey Completion Rate2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    There are several tools for creating online surveys. However, guidance is lacking for some of the decision-making regarding the survey design. This study aims to investigate if one of these choices, navigation, has an impact on the surveys completion rate. We developed our own tool that gave every other respondent one of two different designs. This lets us gather more information than tools such as Google Forms and SurveyMonkey.

    A qualitative approach was used and we let the students of a course at KTH answer questions about that course without having knowledge of this project.

    No conclusions could be made due to some unexpected behaviours which will be explained later in this paper.

    Tearing down barriers of photovoltaics with usability design: Winter is coming2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Photovoltaics has so far not seen much success in Sweden. Recent studies have shown that one of the reasons could be a lack of understanding of the technology, and a feeling that the lack of energy production during winter when a house’s energy consumption is the highest makes photovoltaics uninteresting. The ongoing research project Holistic business models and ICT solutions for prosumers seeks to increase the use of photovoltaics in Sweden, and have created business model concepts in an attempt to break perceived barriers of photovoltaics. My task in this project was to design a tailor made ICT solution with the users’ needs in focus.

    A series of interviews were conducted with households interested in photovoltaics to investigate what information is relevant to understand the business model, and create a starting point for the design process. To ensure a high level of usability of the ICT solution, an iterative design process was conducted with user tests between iterations.

    This resulted in a low fidelity prototype of a smartphone application, consisting of greyscale mockups. The prototype has as much as possible taken the interviewed households’ wishes into account, while adhering to design principles set for usability design. The interviews and user tests also gave some new insights into the informants’ attitudes towards the business model suggested by the research project, which is discussed at the end of the report.

    Time synchronization and data fusion for RGB-Depth cameras and inertial sensors in AAL applications2015In: 2015 IEEE International Conference on Communication Workshop, ICCW 2015, IEEE conference proceedings, 2015, p. 265-270Conference paper (Refereed)
    Abstract [en]

    Ambient Assisted Living applications often need to integrate data from multiple sensors, to provide consistent information on the observed phenomena. Data fusion based on samples from several sensors requires accurate time synchronization with sufficient resolution, depending on the sensor sampling frequency. This work presents a technical platform for the efficient and accurate synchronization of the data captured from RGB-Depth cameras and wearable inertial sensors, that can be integrated in AAL solutions. A case study of sensor data fusion for Timed Up and Go test is also presented and discussed.

    Act or interact? The perceived influence of social media on millennial prosocial behaviours2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With modern communication technology advancements, activist expression has become more common on social media platforms. Especially susceptible to these expressions is the millennial generation, whose lives are greatly permeated by media technology. This thesis aims to explore in what ways the social media platform Facebook inuences millennials’ motivation to engage in substantial prosocial behaviours that are intended to benet other people or society as a whole. Through mixed-method research design, participants’ attitudes towards Facebook as a platform for activism and its inuence on prosocial motivational aspects, was explored. Results indicated that previous habits of supportive engagement and the cost of the supportive action inuenced how the likeliness and motivation to engage in substantial supportive actions was aected by Facebook interaction. More precisely, higher levels of previous engagement, as well as engagement in costly, prosocial actions contributed to an increased motivation to engage further in such actions. Furthermore, social and contemporary aspects showed to play a large part for participants’ motivation to engage in costly and substantial prosocial actions.‌

    Mappning mellan indataoch utdata i löparapplikation2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Today there are many sports tracking applications, but none of them give the runner feedback

    on running technique. The purpose of this study is to do a mapping between input and output in

    a sports tracking application that enables sonification. A scheme for sonification is also

    presented, but not evaluated. The method corresponds to the design phase of an iterative design

    study. The method also includes a survey to give additional information for the choice of

    mapping. A good running technique depends on the step length, relaxation, a straight posture,

    upright head, unclenched fists, setting the front half of the foot down first upon ground impact,

    having ground contact with the foot for long enough,

    the runner’s vertical oscillation, the

    distance between the projection of runner’s centre of gravity to the ground and where the foot is

    set down, the angle at the elbows, that the arms move in counterphase with the legs, the tilt of

    the upper body and a slight tilt from the ankle.

    To measure running technique, GPS, accelerometers, gyroscopes, barometers, pedometers and

    pulse measuring devices can be used. 37 persons answered the survey. Significantly fewer

    respondents wanted feedback on their running technique. The mapping is between speed,

    combustion, distance and vertical displacement to the accelerometer of the smartphone, route to

    the smartphone’s GPS, upright head to a gyroscope, straight posture to the gyroscope of the

    smartphone and a gyroscope at the neck, distance between foot impact and projection of the

    runner’s centre of gravity to an accelerometer at the foot in combination with the smartphone’s

    accelerometer and that the front half of the foot is set down first to two barometers placed by the

    toes and the heel.

    The suggested scheme for sonification is to alter or add to the music that the runner is listening

    to while running. Vertical displacement is sonified by an added

    “twang”-sound, the distance

    between the projection of runner’s centre of gravity to the ground and where the foot

    is set

    down is sonified by altering the music with a highpass-filter with varying cutoff-frequency,

    straight posture is sonified by a lowpass-filter with varying cutoff-frequency, the tilt of the head

    is sonified by the sound of wind added to the music, setting the front half of the foot down first

    upon ground impact is sonified by heavy footstep sounds whenever the heel is set down first

    and having ground contact with the foot for long enough is sonified by a warning siren

    whenever the ground contact is too short.

    Crafting New Interfaces for Musical Expression2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis collects and contextualizes several projects involving artistically directed prototyping where new artifacts have been developed, in multi-disciplinary groups of practitioners, for use in performance contexts. These projects and their resulting publications have been team efforts, and therefore all papers have more than one author. In the introduction, a complementary perspective to that of the publications is offered, engaging with the characteristics of the digital innards of these artifacts and their digital material qualities. The stance that software source code is a design material is argued, and the notion of the crafting coder is used to view processes that use code as material for artistic creation. Code is also prominently featured in the introductory chapter with examples of some of the central components of the sound processing techniques that have been successfully used in the projects described in this thesis.

    The artifacts that are described in the thesis are: The Throat, an instrument for augmenting the singing voice using gestural control in real-time, The Vocal Chorder, a string based instrument using full-body interaction that also allows for audience participation through an installation mode, The Charged Room, a video tracking installation that lets users manipulate sound by moving across a stage, and Nebula, a garment that senses the users movements and responds with sound. These artifacts have been evaluated in the context they are designed for, and not only tested in laboratory settings, to make sure that the knowledge produced is valid. Several performances and peda-gogical courses have been used as empirical foundation for the claims of empowerment, expressivity, and performance qualities ascribed to the developed artifacts.

    Development study of KTH Social´sschedule function2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The usage of KTH Social increases and professors are to a greater extent moving towards

    KTH Social in order to manage their courses. The purpose of KTH Social is to provide all

    course relevant information visualised in one single platform. The purpose of this study is to

    evaluate whether there are development possibilities of the KTH Social schedule area and

    what these are. In a questionnaire, which was formed with theories of Human-computer

    interaction and Time management in mind, KTH students were to answer questions

    regarding the schedule area of KTH Social. Development suggestions were included in the

    questionnaire as well, in order to receive feedback from the students. The results were

    compiled and correlations were made and discussed. The students were positive to the

    development suggestions. Development suggestions within several sections of the schedule

    area could be presented.

    The generalized MAC with partial state and message cooperation2014In: IWCIT 2014 - Iran Workshop on Communication and Information Theory, 2014Conference paper (Refereed)
    Abstract [en]

    We consider a two-user state-dependent generalized multiple access channel (GMAC) with correlated channel state information (CSI). It is assumed that the CSI is partially known at each encoder noncausally. We first present an achievable rate region using multi-layer Gelfand-Pinsker coding with partial state and message cooperation between the encoders. We then specialize our result to a Gaussian GMAC with additive interferences that are known partially at each encoder. We show that the proposed scheme can remove the common part known at both encoders and also mitigate a significant part of the independent interference via state cooperation when the feedback links are strong. Thus, the proposed scheme can significantly improve the rate region as compared to that with only message cooperation.

    Abstract [en]

    During the years 1970-1973, an ambitious research project, the Computer Graphics Project (CGP), was carried out at the laboratory of Information Processing Science at the Helsinki University of Technology. The initial objective of the project was to develop application oriented system solutions for the emerging computer graphics technology, but the activities were soon focused on the problems of producing newspaper text, advertisement, and complete pages using interactive computer graphics. The project and its commercial spin-off, Typlan Systems Projects Oy Ab, as well as the BUNPAPS continuation project 1973-1975 at Brown University, Providence, Rhode Island, created a number of innovative, pioneering solutions for computer aided newspaper production, laying the foundation for the digitalization of media production in the 1980’es. This paper describes the ideas, research, innovations, and products generated by the members of these groups in the period 1970-1975.
