Title
Effects of age, cognitive, and personal factors on PDA menu navigation performance
Abstract
The present study examined the PDA menu navigation performance of younger and older adults. The research focus was directed to the understanding of the combination and interaction of user characteristics with PDA menu navigation performance. In order to detail individual factors that influence user's performance, users' age, spatial ability, verbal memory, the confidence to use technical devices and computer-expertise were studied and related to performance outcomes. Younger and older adults, experienced with the usage of different technical devices, but PDA novices, had to complete four common tasks in the digital diary of an emulated PDA and users' effectiveness and efficiency were surveyed. Even though the users of both age groups had a comparably high computer experience, participants had considerable difficulties to solve the PDA tasks successfully. Especially older adults were strongly disadvantaged when navigating through the PDA menu. Among the user characteristics which were revealed to be essential for performance, spatial abilities were the best predictor to explain PDA performance. In addition, an adequate mental representation of the PDA data structure was decisive for navigation performance, especially in the older adult group.
