The Multipoint Two-Hand Coordinator 1 retains the control mechanism of the Two-Hand Coordinator described elsewhere by Shephard and Lewis ( 1). Both devices require the turning of two lathe-like cranks to effect changes in the position of a target follower. The essential difference between them is that the Multipoint utilizes a stationary hard-rubber plate bearing an irregular "pathway" of small circular brass buttons instead of a revolving disk and a single moving target. Consequently, the Multipoint provides subject-paced (unpaced) tasks while the more familiar Two-Hand Coordinator provides paced tasks.
