| Research Abstract |
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.
