项目摘要

As basic study on IT to improve human-computer interface, the results obtained in this study can be summarized as follows :(1) An eye-gaze input system had been developed, and its usability had been compared with that of a traditional mouse. The eye-gaze input system required less learning time, and led to faster pointing time. The pointing speed doubled that of a mouse. The eye-gaze input system was found to be promising especially for the elderly users, because this new device compensate for the diminished ability of the elderly such as the perceptual, cognitive, and motor functions.(2) How the color arrangement on the touch-panel screen should be implemented had been discussed. Experimental factors were the color used on the back ground and the foreground and the numbers of colors. As a result, these factors did not affect the performance in a touch-panel interface. The background color of a touch-panel was found to affect the subjective (psychological) feeling of users. The black background color tended to be rated positively by the users.(3) The relationship between the slope of a touch panel and the work efficiency or localized muscle fatigue on the upper body had been clarified. When the touch panel was used for shorter periods, the slope of 60 degree was found to be optimal for both standing and sitting tasks. As for the longer duration of a task, it was also suggested that the slope of 60 degrees was desirable from the viewpoints of both work efficiency and localized muscle fatigue on the upper body.

作为信息技术改善人机界面的基础性研究，本研究取得的主要成果如下：（1）开发了一种视线输入系统，并与传统鼠标的可用性进行了比较。眼睛注视输入系统需要更少的学习时间，并导致更快的指向时间。点击速度是鼠标的两倍。人们发现，眼睛注视输入系统特别适合老年用户，因为这种新设备弥补了老年人感知、认知和运动功能等能力的下降。(2)讨论了触摸屏的色彩安排应如何实现。实验因素是背景和前景使用的颜色以及颜色的数量。因此，这些因素不会影响触摸屏界面的性能。触摸屏的背景颜色被发现会影响用户的主观（心理）感觉。黑色的背景颜色往往得到用户的积极评价。(3)阐明了触摸屏的倾斜度与工作效率或上半身局部肌肉疲劳之间的关系。当触摸面板使用较短的时间，60度的斜率被发现是最佳的站立和坐着的任务。至于较长时间的任务，也有人建议，从工作效率和上身局部肌肉疲劳的角度来看，60度的坡度是可取的。
