Image Education ofr the Blind Persons via Vibro-tactile Television

我们的项目之一是澄清两种触觉模式显示方法的区别，一种是在固定手指上显示的方法，如Optacon，另一种是在搜索手指上显示的方法，如触觉电视，这是由研究者的研究小组开发的。触觉电视具有较高的识别性能。另一个项目是为触觉电视开发视频文本。我们制作了1945个汉字的日文汉字文本。发现了许多问题，如录像回放缓慢的视频信号问题和盲人学生的文字显示技术问题。另一个项目是为盲人开发绘图和阅读模式系统。触觉电视系统与盲人个人电脑系统相连。通过这个新系统，盲人用户可以同时获得有关图案和计算机状态的语音和触觉信息。另一个彩色显示项目是在浅色和振冲颜色（称为振冲色调）之间的对应关系上进行的。

One of our projects was to clarify the difference between two methods of tactile pattern display, one of them is a method on a fixed finger such as Optacon and another method is to display patterns on the searching fingers such as tactile television which has been developped by the investigator's research group. Higher recognition performance was resulted by the tactile television than the other.Another project was the development of the video text ofr tactile television. We produced Japanese Kanji(Chinese character) text of 1945 characters. Many problems were revealed, such as, on the videosignal of slow replaying of video tape and on the techniques of display text for the blind born students.Another project was to develop the drawing and reading pattern system for the blind persons. The tactile television system was connected with the personal computer system ofr the blind persons. By this new system, the blind users could get both speech and tactile informations of about patterns and computer status.Another project for color display was carried out on the correspondence between light colors and vibrotactle colors(named as vibro-hue).
