Playing with Context: Explicit and Implicit Interaction in Mobile Media Applications
Stockholm University, Faculty of Social Sciences, Department of Computer and Systems Sciences.
2009 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

This thesis contributes with insights into how aspects of the surrounding physical and social context can be exploited in the design of mobile media applications for playful use. In this work, context refers to aspects of the immediate surroundings – outside of the device – that can be identified and measured by sensors; for instance environmental aspects like sound, and social aspects like co-located people. Two extensive case studies explore the interplay between users, mobile media, and aspects of context in different ways, and how it can invite playful use. The first case study, Context Photography, uses sensor-based information about the immediate physical surroundings to affect images in real time in a novel digital camera application for everyday creativity. The second, Push!Music, makes it possible to share music both manually and autonomously between co-located people, based on so-called media context, for spontaneous music sharing.

The insights gained from the designs, prototypes, and user studies, point at the value of combining explicit and implicit interaction – essentially, the expected and unexpected – to open for playful use. The explicit interaction encouraged users to be active, exploratory, and creative. The implicit interaction let users embrace and exploit dynamic qualities of the surroundings, contributing to making the systems fun, exciting, magical, ‘live’, and real. This combination was facilitated through our approach to context, where sensor-based information was mostly open in use and interpretation, ambiguous, visible, and possible to override for users, and through giving the systems a degree of agency and autonomy. A key insight is that the combination of explicit and implicit interaction allowed both control and a sense of magic in the interaction with the mobile media applications, which together seems to encourage play and playfulness.

Abstract [en]

Push!Music is a novel mobile music listening and sharing system, where users automatically receive songs that have autonomously recommended themselves from nearby players depending on similar listening behaviour and music history. Push!Music also enables users to wirelessly send songs between each other as personal recommendations. We conducted a two-week preliminary user study of Push!Music, where a group of five friends used the application in their everyday life. We learned for example that the shared music in Push!Music became a start for social interaction and that received songs in general were highly appreciated and could be looked upon as 'treats'.

Abstract [en]

Mobile technology has turned the traditionally collective activity of enjoying music into an often private one. New technologies such as wireless ad hoc networks have the potential to re-connect listeners who are now separated by headphones. We report on a field study of Push!Music,a novel mobile music sharing system. Push!Music allows both manual and automatic sharing of music between users through ad hoc wireless networking, and also provides a social awareness of other users nearby. The system was used by 13 subjects for three weeks. In post-study interviews, we identified four categories of results: social awareness, sharing music with friends, sharing music with strangers, andsharing automatically. Based on this, we present implications for design that can be applied not only to mobile music sharing systems, but to mobile media sharing in general: Allow division into active and passive use; enhance the awareness of who, where and when; support reciprocity; and finally, support identity and impression management.
