Abstract

This study investigates the effects of interaction devices on performance of using WWW user interface for older users, and ways to design appropriate user interfaces to enhance browsing and searching performance for older users. Two experiments were designed and conducted to test two hypotheses, that for older novice users, browsing and searching performance and attitudes will be better with a direct manipulation devices rather than with indirect manipulation device. The results indicated that older users using touch screen were faster and less frustrated than older users using voice control and mouse. Moverover, older users using touch screen were faster and less frustrated than older users using voice control and mouse, and older users using mouse and keyboard were less frustrated than older users using voice control
