Abstract [en]

Collaborative consumption-through sharing services-has been promoted as an important step in transforming current consumption patterns toward more sustainable practices. Whilst there are high expectations for sharing services, there are few studies on the potential environmental benefits and impacts of sharing services. This study aims to analyze the potential environmental impacts of a peer-to-peer (P2P) product sharing platform and potential integration with a package drop-off/pick-up service in the urban district of Hammarby Sjostad, Stockholm, Sweden. A life cycle approach is adopted, taking into account product lifetime and use, the potential replacement of conventional products and services, impacts from digital infrastructure and their impacts on the environment. The results indicate that there is significant potential for these sharing services to reduce environmental impacts associated with production and consumption; primarily through avoiding production and reducing the production impacts of new product purchases. The results also illustrate potential synergies to integrate with the package drop-off/pick up service; where the impacts from shared products are further reduced by reducing transportation impacts through improved logistics. However, the results are dependent upon, and sensitive to, a number of methodological choices and assumptions; highlighting the need for greater knowledge on the use environmental assessments of sharing services.

Abstract [en]

Our paper is informed by the recent interest in how the sharing economy and related initiatives mayact as drivers for energy transition and increase well-being and social sustainability in smart sustainable city contexts. We take the example of temporary buildings that for a limited time period offer shared public spaces for public events in the city. Such initiatives are often linked to quadruple helix initiatives in which a local city council, industry and academia join forces to engage citizens in the energy and climate debate, with a temporary building structure as the focal point. The paper argues that such energy initiatives are valuable in terms of social sustainability since they create additional public space for the benefit of citizen debate; contribute scalable solutions and effective infrastructure that can promote energy awareness among citizens. However, there is limited scientific evidence, and a lacking awareness, of the energy efficiency and climate comfort relating to temporary buildings for public use. Our preliminary results show that such factors risk to obscure the well-intended objectives of quadruple helix initiatives to support energy transition. The revealed problems of a Stockholm use case suggest that in spite of significant social and economic impact resulting from curated public events which attracted an unprecedented number of visitors, energy consumption, climate comfort and indoor air quality are nevertheless important factors that also must be considered in the design and implementation of temporary building structures. The paper concludes that better climate controlshared economy thinking is necessary at theearliest stage of a planning process, for temporary buildings to be successful.

Abstract [en]

COMPEIT creates a web-based system for highly interactive, personalised, shared media experiences. The new technologies will improve the feeling of being together in a shared mediated space and support interaction and collaboration between people who are separated in time or space.

Immersive spaces 1.0 is a software component for the COMPEIT presence system with a feature set that allows users to interact and perform shared actions in virtual spaces, simply using their web browser. The main features are called SharedSpace, a virtual 3D environment which users can redesign and populate by scaling and rearranging their avatar-like live videostream representations; and PixelPresence which is an overlay technique that offers a pixelated view of a livestream, hereby adding an ambient and discrete presence filter, which indicates movement and subtly prompts users to enter a mediated interaction. 

The COMPEIT presence system supports individuals and distributed groups who want to stay close with one another on a regular basis, ready to spontaneously interact in mediated and virtual space. Feedback from users and user requirements in WP2 showed that people want to be subtly aware of what others are doing, and if they are at a particular place at a given time – which, of course, is quite different to keeping a videolink open 24/7. Whether the context is professional or social, ambient forms of presence are thus called for, in order to support gradation and, perhaps more importantly, to prompt users to join a shared virtual space.

Abstract [en]

SharedSpaces is a WebRTC design prototype that creates a virtual media space where people can mingle and interact. Although you are in different locations, you appear side by side in front of a chosen backdrop. This interactive installation addresses spatial and social connectedness, stressing the importance of integrating architectural and spatial features to support complex social dynamics in mediated interaction. The tool engages users in manipulating their real-time videostreams, creatively co-designing a shared mediated space that fits a contextual need. It supports social dynamics by allowing users to draw and paint together and to move and resize video streams. Further, it enhances grounding and social cues by merging videostreams and space, representing users as if they were in the same space. Standard and easily available equipment is used. Recent user studies show that a seamless integration of space, social dynamics and shared activity benefits the experience of presence, naturalness, immersion/engagement and social connectedness.

Abstract [en]

The work presented here seeks an integration of spatial and social features supporting shared activities, and engages users in multiple locations to manipulate realtime video-streams. Standard and easily available equipment is used together with the communication standard WebRTC. It adds a spatial quality of experience by representing the users anywhere on the screen, with easily changed diverse backdrops, inviting users to co-design a shared mediated space. User studies show that a seamless integration of space, social dynamics and shared activity benefits the experience of presence, naturalness, immersion/ engagement and social connectedness. The results inform a discussion about spatial and social connectedness, stressing the importance of design to integrate architectural/spatial features and support complex social dynamics in mediated interaction.

Abstract [en]

This paper introduces a virtual tour, Visit the Louvre, designed specifically to engage older adults in an immersive visit through part of the Louvre by a distant real-life guide. An initial diary study and a creative workshop were conducted to understand the needs and values of older adults and how to support participation to virtual museum visits with a video-based communication system. Preliminary results show that ‘virtual visitors’ experienced high levels of social and spatial presence; immersion and engagement were quite high independent of the level of interactivity of the guide, or the presence of others.

Abstract [en]

The physical workplace, a hub for communication, collaboration and co-located interaction can no longer be taken for granted. Today, the design of intelligent interactive media, physical products and ubiquitous environments has passed the phase of being technology-driven. Meaning, insight and experience are now the key design drivers for the bridging of digital and physical design. We foresee how new interconnected knowledge systems – objects/devices, buildings and even cities created from web-based services and IoT – thoroughly transforms CSCW. A wide spectrum of services already invites users to seamlessly move between real and virtual workspaces, using a range of previously separated media channels. This interdisciplinary workshop welcomes researchers and practitioners to a day-long exchange targeting User eXperience (UX) and, specifically, the relationship between social and spatial connectedness in mediated and virtual work environments. Examples from ongoing research and developments informs a discussion on how the borders between the virtual and real become increasingly obsolete.

Abstract [en]

As part of a public dissemination impact activity within the Mediating Presence project of EIT ICT Labs in 2013, partners were invited to a series of Mediated Seminars, seeking to identify valuable trends relating to the future of the media industry in general, and to smart spaces in a particular. The participants reviewed and discussed all the recent publications available via the EIT ICT Labs Web site (www.eitictlabs.eu/publications), as well as a wide range of publicly available reports and white papers. As a result of this process, the idea was put forward to produce four films that would trigger reflection within the research community about the technical development relating to "smart spaces". This represents a new and experimental form of outreach and dissemination for the activity.

The workshop was successfully concluded, with preliminary drafts for scripts, intended for the creation of four short films, handed over to four different film producers by responsible activity researchers in four different cities (Delft, Helsinki, Luleå, and Stockholm). Tentative versions of three films were screened according to plan at the Espoo SSP Results Day event in December, from which valuable feedback was received, allowing for the first three films to be slightly revised and completed at the end of December. In parallel, the fourth film was realised in two parts and completed at the end of December: Analogue Friday 1 and 2.

Abstract [en]

COMPEIT is a 3-year EU 7th framework project and focuses on a web-based system for highly interactive, personalised, shared media experiences by developing technologies that A) enrich social connections, B) improve the feeling of being together in one shared space and C) enhance collaboration whilst being separated in time or space. COMPEIT takes the view that Internet-based distribution will transform traditional broadcasting towards higher levels of interactivity and integration with virtual and augmented reality, enabled by advanced web technologies and the proliferation of tangible devices. The project addresses Quality of Experience as a key variable in the experience of media production and consumption systems.

A first mock-up of the COMPEIT system has been put together. It illustrates technical components from WP 4 (Mediated Presence Components); services from WP 5 (New Media Services); and D3.2 Initial System Specification. It informs further research towards D3.4 First Prototype.
