| Research Abstract |
In this study, basic technologies for the development of man-machine system were discussed in the light of perceptual, cognitive and motor-control functions. We investigated how the layout of steering wheel mounted switch, the display direction, and the number of layers in display design affected the performance while interacting with aging factor. The analysis of performance and mental workload especially for the older adults showed that the memory structure considerations in display design led to higher performance. Eye-gaze input systems or the touch-panel interfaces were found to be effective in particular for older adults. However, the accuracy of pointing operation and the directional effect by the eye-gaze input system have not been identified until now. As for the touch-panel interface, the effects of display direction of targets on the pointing performance have not been clarified. The pointing accuracy and the directional effect of an eye-gaze input system was identified. Moreover, how the display direction (vertical or horizontal) in a touch-panel interface was examined. Older Internet users are increasing more and more. The amount of display information that is proper for older adults has not been clarified. It was showed that the amount of information influenced Web navigation especially for older adults, and the decline of perceptual, cognitive and motor ability was strongly related to the increase of Web navigation time.
