Measurement of the Right Hand Operable Area under a Simulated Driving Situation

Abstract

To improve the operability for drivers with wider range of body size, the reach area of driver desks was measured under a simulated driving situation with a natural seat position in which shorter drivers were seated more closely to the desk than taller drivers. Simulated push buttons were used in exp.1 and actual ones in exp.2. The recommendable area in which over 80% of the participants evaluated the position of buttons as "not difficult to push" in exp.2 was larger than that in exp.1. It was considered that the area in exp.1 was applicable to buttons required for precise pointing, while that in exp.2 was to crude pointing.
