Comparative Research on the Remote Control Interface Cognition Oriented to Universal Design

The universal design evaluation of projector remote control interface has important meaning to the businesses and users, which is a multi-user-oriented hand-held device. The article first discussed the concepts and principles of universal design, as well as the research methods of PPP, USS, etc. On this basis, it selected EPSON, SONY, and SANYO projector remote controls, successively had tests on the product used phases from unfamiliar to familiar through PPP methods, and then had comparative tests for 7 items and 23 categories including Comfort, Convenience and Clarity, Freedom, Accuracy, Consistency, Fault tolerance, etc. Finally, it put forward the improved suggestions on comprehension button interface, the number of the button and operating procedures etc.
