| Summary: | 碩士 === 朝陽科技大學 === 工業工程與管理系碩士班 === 101 === For lower limb disabled driving a car mechanical manual controllers are mostly used to control the brake and accelerator. However , the joystick is mostly used to drive an airplane; is seldom used in driving a car. This study was aimed at evaluating usability of the joystick-style controller and mechanical manual controller for the lower-limb disabled driving a car.
20 participants were divided into experimental and control groups （10 persons for each group ）. The experimental group was lower disabled the control group was the non-disabled. Each subject performed driving simulator experiment with the two hand controllers, respectively. Driving performance, physiological load and subjective evaluation data were collected during the experiment.
Both groups had significantly better driving performance with the joystick-type hand controller than that of the mechanical manual one. They also had significantly lower physiological load （percent of maximal heart rate） with the joystick-type hand controller than that of the mechanical manual one. However, they had similar subjective assessment between the two tested controllers. This study provides an advanced investigation for applying joystick n driving a car. But, further experiment should be conducted on the real road driving for confirming safety and efficiency
