Task-Based Focus and AdHoc-Focus-Territory: Novel Concepts for Shared Interactive Surfaces

Shared Interactive Surfaces allow co-located users to collaboratively work on a task. As current technology often is not able to distinguish between different users, there is a potential for concurrent conflicting actions of multiple users, leading to unwanted results and accordingly frustration. With our concepts for Task-Based Focus and AdHoc-Focus-Territory we provide light-weight solutions Integrated in our toolkit TUIOFX - for designers of multi-user, multi-touch applications. Our solution helps to overcome some of the problems of anonymous touch input, without an immediate need for more heavy-weight mechanisms like user identification.
