A Mischief of Mice: Examining Children’s Performance in Single Display Groupware Systems with 1 to 32 Mice

Abstract

Mischief is a system for classroom interaction that allows

multiple children to use individual mice and cursors to

interact with a single large display [20]. While the system

can support large groups of children, it is unclear how

children’s performance is affected as group size increases.

We explore this question via a study involving two tasks,

with children working in group sizes ranging from 1 to 32.

The first required reciprocal selection of two on-screen

targets, resembling a “swarm” pointing scenario that might

be used in educational applications. The second, a more

temporally and spatially distributed pointing task, had

children entering different words by selecting characters on

an on-screen keyboard. Results indicate that performance is

significantly affected by group size only when targets are

small. Further, group size had a smaller effect when

pointing was spatially and temporally distributed than when

everyone was concurrently aiming at the same targets.
