Designing for multi-user interaction in the home environment: Implementing social translucence

© 2016 ACM. Interfaces of interactive systems for domestic use are usually designed for individual interactions although these interactions influence multiple users. In order to prevent conflicts and unforeseen influences on others we propose to leverage the human ability to take each other into consideration in the interaction. A promising approach for this is found in the social translucence framework, which was originally described by Erickson & Kellogg. In this paper, we investigate how to design multi-user interfaces for domestic interactive systems through two design cases where we focus on the implementation of social translucence constructs (visibility, awareness, and accountability) in the interaction. We use the resulting designs to extract design considerations: interfaces should not prescribe behavior, need to offer sufficient interaction alternatives, and previous settings need to be retrievable. We also identify four steps that can be integrated in any design process to help designers in creating interfaces that support multi-user interaction through social translucence

Social Navigation in a Location-Based Information System

Much of contextaware application research has dealt with the technical aspects of context capturing and how to interpret the context of a user. Little effort has been spent on the experience and usage of these systems. This thesis will present the general aspects of social awareness and present an example on how these concepts can be implemented into a location-based information system to help users navigate a potential information overload. This thesis also states that giving the users an experience of not being alone in the system increases the pleasure of using such a system. However this implies a decrease in privacy. To demonstrate these ideas I will describe a locationbased information system, GeoNotes, built by a group of researchers at SICS, the Swedish Institute of Computer Science. I will state a set of interaction requirements for how to extend the GeoNotes system with functionality for social awareness. Furthermore I will set up functional requirements for those interaction requirements to after implementation be able to conclude which interaction requirements I have been able to implement for. I will also give suggestions on how to position users in a WLAN. The deliverable from this project is a locationbased information system with functionality for social awareness. However, it was not within this project to test the system on true users. Therefore the statement that this functionality can help users to navigate a potential information overload is still just a hypothesis. To retrieve the position of a user in a W-LAN a packet is sent to all base stations in the network. In the first returning packet the mac address of contacting base station is extracted. Each base station is therefore a unique position. Triangulation was discarded due to its sensitivity to noise and weather circumstances, although a system that uses triangulation would have offered a much higher granularity

Supporting Location Privacy Management through Feedback and Control

Participation in modern, socially-focused digital systems involves a large degree of privacy management, i.e. controlling who may access what information under what circumstances. Effective privacy management (control) requires that mobile systems’ users be able to make informed privacy decisions as their experience and knowledge of a system progresses. By informed, we mean users be aware of the actual information flow. Moreover, privacy preferences vary across the context and it is hard to define privacy policy that reflects the dynamic nature of our lives. This research explores the problem of supporting awareness of information flow and designing usable interfaces for maintaining privacy policies ad-hoc. We borrow from the world of Computer Supported Collaborative Work (CSCW) and propose to incorporate social translucence, a design approach that “supports coherent behaviour by making participants and their activities visible to one another”. We use the characteristics of social translucence, namely visibility, awareness and accountability in order to introduce social norms in spatially dispersed systems. Our research is driven by two questions: (1) how can artifacts from real world social interaction, such as responsibility, be embedded into mobile interaction; and (2) can systems be designed in which both privacy violations and the burden of privacy management is minimized. The contributions of our work are: (1) an implementation of Buddy Tracker, privacy-aware location-sharing application based on the social translucence; (2) the design and evaluation of the concept of real-time feedback as a means of incorporating social translucence in location-sharing scenarios; and finally (3) a novel interface for ad-hoc privacy management called Privacy-Shake. We explore the role of real-time feedback for privacy management in the context of Buddy Tracker. Informed by focus group discussions, interviews, surveys and two field trials of Buddy Tracker we found that when using a system that provided real-time feedback, people were more accountable for their actions and reduced the number of unreasonable location requests. From our observations we develop concrete design guidelines for incorporating real-time feedback into information sharing applications in a manner that ensures social acceptance of the technology

Keeping ubiquitous computing to yourself: a practical model for user control of privacy

As with all the major advances in information and communication technology, ubiquitous computing (ubicomp) introduces new risks to individual privacy. Our analysis of privacy protection in ubicomp has identified four layers through which users must navigate: the regulatory regime they are currently in, the type of ubicomp service required, the type of data being disclosed, and their personal privacy policy. We illustrate and compare the protection afforded by regulation and by some major models for user control of privacy. We identify the shortcomings of each and propose a model which allows user control of privacy levels in a ubicomp environment. Our model balances the user's privacy preferences against the applicable privacy regulations and incorporates five types of user controlled 'noise' to protect location privacy by introducing ambiguities. We also incorporate an economics-based approach to assist users in balancing the trade-offs between giving up privacy and receiving ubicomp services. We conclude with a scenario and heuristic evaluation which suggests that regulation can have both positive and negative influences on privacy interfaces in ubicomp and that social translucence is an important heuristic for ubicomp privacy interface functionality

Citizen noise pollution monitoring

Trabajo presentado a la 10th Annual International Conference on Digital Government Research: Social Networks: Making Connections between Citizens, Data and Government, celebrada en Puebla (México) del 17 al 21 de mayo de 2009.In this paper we present a new approach to monitor noise pollution involving citizens and built upon the notions of participatory sensing and citizen science. We enable citizens to measure their personal exposure to noise in their everyday environment by using GPS-equipped mobile phones as noise sensors. The geo-localised measures and user-generated meta-data can be automatically sent and shared online with the public to contribute to the collective noise mapping of cities. Our prototype, called NoiseTube, can be found online.This work was partially supported by the EU under contract IST- 34721 (TAGora).

Persistent virtual identity in community networks: Impact to social capital value chains

Community networks are digital infrastructures designed to strengthen bonds and build social capital between members of a community, facilitating accomplishment of goals. As we consider how community network implementations can be improved, we recognize the potential that social translucence and activity notification introduces to other forms of CSCW. We investigate how the underlying notion of persistent virtual identity---established at logon---impacts user perception of community networks and their social capital production process. To approach this question, we introduce a design model that reconciles various computer-mediated communication research contributions with support for typical community network scenarios of use. Using this model, we perform an inspection on existing community network implementations. Based on the insight gained through this analysis, we introduce a generic prototype that allows survey of user reaction to community network design elements under differing conditions of persistent virtual identity implementation and usage motivation---the results frame a value-chain understanding of conceptual tradeoffs

How do knowledge workers cope with their everyday job

Knowledge work, which forms a large part of modern economy, often involves collaboration. In order not to overemphasise either the transactional or the communicative aspect of collaboration, attitudes and technologies may have to change. Data from a survey show how knowledge workers manage their time and tasks using straightforward office technologies. Enhanced context awareness could help both the communication initiator and the communication target. This is a matter of behaviour and a chance for technology

PRIMA — Privacy research through the perspective of a multidisciplinary mash up

Based on a summary description of privacy protection research within three fields of inquiry, viz. social sciences, legal science, and computer and systems sciences, we discuss multidisciplinary approaches with regard to the difficulties and the risks that they entail as well as their possible advantages. The latter include the identification of relevant perspectives of privacy, increased expressiveness in the formulation of research goals, opportunities for improved research methods, and a boost in the utility of invested research efforts

Making Space for Stories: Ambiguity in the Design of Personal Communication Systems

Pervasive personal communication technologies offer the potential for important social benefits for individual users, but also the potential for significant social difficulties and costs. In research on face-to-face social interaction, ambiguity is often identified as an important resource for resolving social difficulties. In this paper, we discuss two design cases of personal communication systems, one based on fieldwork of a commercial system and another based on an unrealized design concept. The cases illustrate how user behavior concerning a particular social difficulty, unexplained unresponsiveness, can be influenced by technological issues that result in interactional ambiguity. The cases also highlight the need to balance the utility of ambiguity against the utility of usability and communicative clarity.Comment: 10 page

Tribal metaphors in social game design: creating conflict and camaraderie through context

This paper briefly explores the emergence of tribal patterns in social play. The formation of community groups is not just a result of game design, but a fundamental part of the social nature of the species. Tribal effects, such as favouritism towards fellow group members, have been studied by social psychologists for decades (e.g. [22,15,7]). We highlight some specific existing mechanics that enable and encourage this kind of behaviour in social games, and identify the importance of social feedback in generating tribal feelings. An experiment is described, that explores the minimal conditions of tribal behaviour player groups in social games. Specifically, it identifies the importance of feedback on social context in supporting the emergence of in-group favouring tribal play
