Assistive tools for PC operation to back up visually impaired working, was studied. The following results were clarified.1.Experiment performed to evaluate and estimate the human-computer system by severe visually impaired person. From the analytic model designed, the clarified drawback was that the graphic operation was serious bottle neck for the visually impaired persons in the GUI system.2.An interactive tactile graphic device as mean of PC accessible system was introduced. Experiments by this system performed to examine possibility of the layout task which contains searching and moving figures. Result showed that participants made high skilled layout tasks with the cooperation of the screen reading device.3.Fatigue accompanying with the introduced system examined. Participants evaluated mentally and physically that the system had not so severe defect to cause stress and fatigue.4.A new tactile device was developed further to improve usability. Major characteristic of the device is that a position of tactile graphic surface responds directly by a force/torque sensor mounted in the device. Alternate function by the mouse such as the pointing and scrolling is realized easily.5.In addition to the pointing and scrolling function, the drawing function was functioned to the device. Operation to figures by visually impaired participants improved, and further written figures by users made possible to store and retrieve from/to a PC. Since multimedia access diversified, the new device is promise to become an assistive tool to extend occupation for severe visually impaired persons.

研究电脑操作辅助工具，以支援视障人士的工作。对以下结果进行了澄清：由严重视障人士进行的人机系统评估与评估实验。从设计的分析模型来看，明确的缺点是图形化操作是GUI系统中视障人士的严重瓶颈。介绍了一种交互式触觉图形设备作为PC可访问系统的代表。通过实验验证了包含搜索和移动图形的布局任务的可行性。结果表明，在屏幕阅读设备的配合下，被试完成了高技能的布局任务。对所介绍的系统进行了疲劳试验。参与者在精神上和身体上评价系统没有严重的缺陷导致压力和疲劳。进一步开发了一种新的触觉装置，以提高可用性。该设备的主要特点是通过安装在设备中的力/扭矩传感器直接响应触觉图形表面的位置。4 .可轻松实现鼠标的指向、滚动等交替功能。除了指向和滚动功能外，还对设备进行了绘图功能。视障人士对数字的操作得到改善，而用户书写的数字也可以在个人电脑上存储和检索。随着多媒体接入方式的多样化，该设备有望成为重度视障人士扩展职业的辅助工具。
