Motivation

In ubiquitous computing environments, users will interact with a broad variety of smart artefacts over time. Some of these artefacts are strictly personal (e.g., PDAs) while others are accessible by multiple persons (e.g., public displays). Since most activities imply a permanent shift between individual and cooperative work, smooth transitions between different situations are essential. In this context, the main constituents of a situation are information, people, and devices. A change of situation occurs as soon as one parameter is altered. For example, a small group of people working on a certain document transits from one situation into another as soon as they change the set of artefacts. This workshop addresses the associated issues.

Issues and Questions

• How can artefacts and systems support the user when migrating from public to personal artefacts and back?
• How can personal/private information be accessed on large displays that tend to be rather public by nature (in contrast to, e.g., PDAs)?
• What has to be designed differently for temporarily personalized devices in comparison to truly personal devices? How can it be ensured that the personalization of public devices is only temporary, e.g. how can it be guaranteed that no personal information remains?
• How is personal information handled during cooperative work? What are the implications of bringing personal information in a (public) collaboration context? What is an appropriate notion of “personal” and “public” which covers this transition in a natural manner?
• What are natural forms of interaction to publish or partially publish personal information (which might reside on personal devices) on public displays?
• Can or should there be an adapted visualization of personal information on public displays? This implies: How can information or parts of information be marked as personal in an unobtrusive manner?
• How does the surrounding context influence the functionality and appropriate access and interaction mechanisms?
• In which ways can personal and public devices interact?
