Abstract
Subjects' 3-D pointing movements were mapped to a 2-D computer display in three conditions as a function of hand speed: constant gain, discrete gain increase, and continuous gain increase. Analysis of hand and cursor kinematics demonstrated that discrete gain change provided no real advantage, and p:rformance suffered with continuous gain change as movement proftles were disrupted. Reduced footprint was traded for increased difficulty in decelerating to the targets. A detailed analysis of movement time as a function of distance and target width suggests that a better strategy for improving pointing performance is to improve device resolution, and use higher constant control-display gain.
