Abstract
The fast aging of many western and eastern societies and their increasing reliance on information technology create a compelling need to reconsider older users’ interactions with computers. Changes in perceptual and motor skill capabilities that often accompany the aging process bring important implications for the design of information input devices. This paper summarizes the results of a laboratory study with different information input device. Three different input devices; mouse, touch screen and eye-gaze; were analyzed concerning efficiency, effectiveness and mental workload with respect to the age group of the computer user. The results derived from data of 90 subjects between 20 and 75 years show that regardless of participant’s age group the best performance in terms of short execution time results from touch screen information input. This effect is even more pronounced for the elderly.
