Abstract

We discuss the rationale for the use of multi-layered annotations and telepointers in the context of group activities conducted in multimedia rooms. In this setting, users rely on large interactive displays, desktop or laptop computers, and mobile devices. We have designed a synchronous collaboration environment termed Strata that supports interaction and collaboration among local and remote participants who share a workspace and communicate by pointing and annotating on objects. In the proposed environment, telepointers increase awareness of other users and their intentions, whereas transparent layers facilitate the production of annotations. Layers can be activated or deactivated depending on each user's preferences and interests, thus reducing clutter and facilitating coordination. We present the design and prototypical implementation of Strata as well as encouraging results from preliminary evaluations.
