AVOIDING INTERFERENCE THROUGH TRANSLUCENT INTERFACE COMPONENTS IN SINGLE DISPLAY GROUPWARE

Abstract

Our research concerns the design of interface components tailored for single display groupware (SDG) where multiple co-located people, each with their own input device, interact over a single shared display. In particular, we are concerned with 'interference' effects, where one person's raising of an interface component (e.g., an menu) can impede another's view and interaction on the shared screen. Our solution uses translucent interface components, where others can see through the obstructing component and continue their work underneath it. Our in-progress evaluation suggests this design lessens interference effects.
