Proposal of New Paradigm for Hand and Foot Controls in the Context of Spatial Compatibility Effect
Many workstations make heavy use of the hands for primary control of a process. If some control tasks can be assigned to the feet, there would be an obvious benefit in having the hands free for other tasks that require a higher level of precision and dexterity. Spatial compatibility between displays and controls is a weighty determinant of performance. This paper proposes a research framework that aims to
Design and conduct a series of spatial compatibility experiments for measuring human subjects’ response preferences and choice reaction times at different con- figurations of displays and hand and foot controls.
Investigate the effect of interaction between hand and foot controls in such con- figurations.
Determine the optimum positional mappings of hand and foot controls with visual signals presented at different planes of displays.
The objective is progress toward an optimal human-machine interface design for improving overall system performance.
