Linearity of human commands for telerobotics
Conference Paper, Proceedings of 16th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC '94), pp. 1039 - 1040, November, 1994
Abstract
We identify frequency limitations on linearity in two-dimensional (2-D) motion for three subject groups: young (mean and /spl sigma/: 23/spl plusmn/3), old (72/spl plusmn/2), and movement-disabled (65/spl plusmn/16). The linearity of the relationship between input and output - i.e., between target tracking signals and resulting human upper extremity motion - is quantified using adaptive coherence estimation. We show that linearity decreases with input frequency. Old and disabled subjects' 2-D motion is almost completely nonlinear. Nonlinear filtering therefore will likely improve precision in rehabilitative and surgical teleoperation.
