ABSTRACT
The development of switch system which leads not only to a faster response and less frequent visual off road but also to quick learning would be useful for the purpose of enhancing safety. The usability is, however, not evaluated on the basis of learning characteristics of such measures as operation time and frequency of visual off road. The evaluation of usability of switch systems by means of ease of learning is very useful for automotive designers of cockpit modules. An attempt was made to investigate the learning characteristics of the developed integrated switch system using face direction with the traditional touch-panel interface.
