Abstract:

An experimental investigation was conducted to examine a descriptive model for hand motion under discrete uncertainty of the stimulus set. The design and implementation of an automatic, on-line, data collection device using cyclegraphic motion collection methods is described. Eight subjects were exposed to 2.2 to 3 bits of choice uncertainty. Response times, error rates, and hand motion distances were collected and analyzed. Hand motion distances were compared to straight line distances used in control panel design. Further investigation indicated how the distributions of hand motion distances, for any stimulus, fit normal curves, and how variations in subject performance were significant. Perceptual aspects of the task and operator strategies are discussed. Further study is suggested. Author
