Abstract

Enabling group collaboration is important incomputer graphics today. We have developed aframework that supports multiple pointing devices toexplore the collaborative utility of multiple mice andlaser pointer interaction in graphical environments.Because most pointing device comparisons are done inthe context of single user performance, very little isknown about the affordances of collaborating withmultiple pointing devices. We present an experimentalcomparison of mouse pointer to laser pointerinteraction in a problem-solving task involving groupsof one, two, and three people. We show thatcollaborative performance is largely orthogonal tomotor performance and that the interaction patternsare dependent on the task and on the group size. Thissuggests that the collaborative characteristics of apointing device are just as important as the physicalcharacteristics that are usually given the mostattention, such as precision and accuracy.
