高齢者の知覚・認知・運動特性を考慮した入力ディバイスの開発

本研究从知觉、认知和运动控制三个方面探讨了人机系统开发的基本技术。我们研究了方向盘安装开关的布局，显示方向，以及显示设计中的层数如何影响性能，同时与老化因素相互作用。对显示器设计中的记忆结构因素进行了分析，特别是对老年人的分析表明，记忆结构因素导致了更高的显示器性能。人们发现，目光输入系统或触摸面板界面特别对老年人有效。然而，指向操作的准确性和视线输入系统的方向性效果直到现在还没有被识别。至于触摸屏界面，目标的显示方向对指向性能的影响尚未明确。确定了视线输入系统的指向精度和方向效应。此外，如何在触摸面板界面的显示方向（垂直或水平）进行了检查。老年网民越来越多。适合老年人的显示信息量尚未澄清。研究结果表明，信息量对网络导航有显著影响，尤其是老年人，感知、认知和运动能力的下降与网络导航时间的增加密切相关。

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.
