项目摘要

Our research has three categories. The first is hardware developing, such that two-dimensional (2-D) tactile display, Braille and tactile pattern reader. The second is software system which supports these hardware and original Braille system such that automatic Braille translator which has two way, one is ordinary expression into Braille sentence and the other is reverse conversion. The third is comparative investigation of mathematical Braille expressions which are used higher education. On the other hand, as manufacturing cost of the 2-D tactile display parts was very expensive, we suspended to invest our research budget in Braille reader by third vender.The characteristic result of the researches were as follows.(1) Two-dimensional tactile display.Satisfying results have been performed by experiment based on display parts ordered from outside suppliers last year. In this year, we made an attempt to compose a B5 size tactile display which has 158 X 229 dots matrix. Though the first schedule was late for the previous reason, there is no problem because the remained problem is lack of man power related simple task work.(2) Braille and tactile pattern reader.This equipment is a sheet reader machine which can read three different sizes of embossed sheets (B5, A4, letter size). Available width is 215mm, and each interval of the sensor is 0.5mm. First target has been performed.(3) Japanese natural language processing.A machine readable dictionary for Braille translation and analysis system for Japanese have been developed. Currently we are considering the logical notation of standard Japanese Braille. The next step is to make a high quality system which is combined this natural language processing system and substantiality of dictionary.(4) Miscellaneous.Braille display terminal and Braille /tactile pattern embosser throughout the first plan. We are investigating next design as intelligent CAI system for visually-handicapped.

我们的研究分为三类。首先是硬件开发，例如二维（2-D）触觉显示器、盲文和触觉图案阅读器。二是支持这些硬件的软件系统以及原有的盲文系统，比如自动盲文翻译器有两种方式，一种是普通表达成盲文句子，另一种是反向转换。三是高等教育中使用的数学盲文表达式的比较研究。另一方面，由于二维触觉显示部件的制造成本非常昂贵，我们暂停了对第三方供应商盲文阅读器的研究预算的投入。研究的特征结果如下：（1）二维触觉显示。基于去年从外部供应商订购的显示部件进行的实验取得了令人满意的结果。今年，我们尝试构建B5尺寸的158 X 229点阵的触觉显示器。虽然由于之前的原因，第一个时间表迟到了，但没有问题，因为剩下的问题是缺乏人力相关的简单任务工作。（2）盲文和触觉图案阅读器。该设备是一种纸张阅读器机器，可以阅读三种不同的内容浮雕纸张尺寸（B5、A4、信纸尺寸）。可用宽度为215mm，传感器每个间隔为0.5mm。第一个目标已经完成。(3)日语自然语言处理。开发了日语盲文翻译和分析系统的机器可读词典。目前我们正在考虑标准日语盲文的逻辑符号。下一步是制作一个高质量的系统，将这种自然语言处理系统与词典的实质性相结合。(4)杂项。盲文显示终端和盲文/触觉图案浮雕贯穿第一个计划。我们正在研究下一步的设计，即针对视障人士的智能 CAI 系统。
