PERFORMANCE OF AUTOMOTIVE HAND CONTROLS
This paper describes an experimental study of automotive hand controls designed for people with lower body handicaps. These controls permit a driver to perform with one hand the brake and accelerator operations usually accomplished with standard foot controls. The other hand is free to operate the steering wheel. In a simulation of the driving task, subjects used various hand controls and standard foot controls for the simultaneous control of acceleration and heading angle in dual-axis compensatory tracking. Integral absolute error and describing function data were obtained. The results of this simulation show that the hand control mechanisms can perform more effectively than the standard foot pedal arrangement in the control of acceleration. Subjects were also able to control vehicle heading angle more effectively while using the hand controls. These differences between foot and hand controls are statistically significant, smaller differences in peformance are seen between the various hand control mechanisms. A presentation of the describing function results provides an insight into the nature of the differences in control performance.
