Study of Virtual Button Design in a Vision Based Interface

Abstract

The current study aims to improve the operating performance on vision based interface. Its main objective is to evaluate the virtual button design in a vision based interface by verifying the interface elements which are trigger time, button size, and button position of the virtual buttons. This study developed a vision based interface with virtual button menu to examine the differences in operating time and error rate when adjusting the interface elements. The participants are 30 college students aged between 21 and 29 in Taiwan. The results showed trigger time, button size, and button position has significant impact on operation time and error rate. To adjust trigger delay time appropriately, the error rate can be effectively reduced.
