Control performance with three translational degrees of freedom

摘要

For multiple degree-of-freedom(DOF)systems, it is important to determined how accurately operators can control each DOF and what influence perceptual, infor- mation processing, and psychomotor components have on performances. Sixteen right-handed male students participated in 2experiments: 1 involving positioning and 1 involving tracking with 3 translational DOFs. To separate perceptual and psychomotor effects, we used 2 control-display mappings that differed in the cou- pling of vertical and depth dimensions to the up-down and force-aft control axes.
