However, most interfaces are oriented towards adults. To fill this void, we are developing a collaborative digital library application for young children. Our prototype system, QueryKids, offers a graphical interface for querying, browsing and reviewing search results for multiple children using multiple mice. Early studies show that QueryKids successfully supports one user searching for media, and our informal observations show that two users have ...

This is especially important in modeless user interfaces with no separate modes for writing and gesturing. In this paper, we propose to give feedback continuously while users draw, as this allows immediate correction of minor

To successfully support these situations, computer-supported co-operative work (CSCW) concepts and technologies face new challenges. One of the most fundamental concepts for cooperation is sharing. By analyzing applications of sharing in the context of ubiquitous computing it can be shown that ubiquitous computing enables an extended view on sharing. In this paper, we show that this extended view seamlessly integrates the view of “traditional” CSCW and additionally incorporates ubiquitous, heterogeneous, and mobile devices used in a common context.

New hardware de-velopments such as multi-user touch-sensitive tabletop surfaces offer new pos-sibilities to support games with information technology. This paper analyzes the properties of games that are relevant for choosing an appropriate hardware setup, e.g. the need for public or personal data for different players. These prop-erties lead us to a categorization of games. Based on these results, possible hardware configurations for different game categories are discussed. Four sam-ple games are presented by which the influence of the hardware setup on the game has been studied. The paper concludes with the lessons learned from our classification of games and their weaknesses and the next steps we are going to make.

Although the domain of these applications is very heterogeneous, existing frameworks provide only limited flexibility to integrate diverse groupware applications in a meaningful way.
