While the system\u00a0can support large groups of children, it is unclear how\u00a0children\u2019s performance is affected as group size increases.\u00a0We explore this question via a study involving two tasks,\u00a0with children working in group sizes ranging from 1 to 32.\u00a0The first required reciprocal selection of two on-screen\u00a0targets, resembling a \u201cswarm\u201d pointing scenario that might\u00a0be used in educational applications. The second, a more\u00a0temporally and spatially distributed pointing task, had\u00a0children entering different words by selecting characters on\u00a0an on-screen keyboard. Results indicate that performance is\u00a0significantly affected by group size only when targets are\u00a0small. Further, group size had a smaller effect when\u00a0pointing was spatially and temporally distributed than when\u00a0everyone was concurrently aiming at the same targets.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mischief is a system for classroom interaction that allows\u00a0multiple children to use individual mice and cursors to\u00a0interact with a single large display [20].
