Assistive study for reception of non-verbal contents on the Web by severe visually impaired

严重视障人士很难接收非语言内容，例如网上的数字和图像。本研究旨在实现一种将非语言信息转化为时空触觉图像的思想。此外，合成语音呈现与触觉表示上的深位置相关。主要研究结果如下：1. Web算法的设计由于要承受触觉图形的放大/缩小功能，同时还要有相同的声音呈现，因此需要特定的算法。Adobe Flash类型的文件用于在Web软件中进行验证。2.交互式触觉显示器的发展当希望通过触觉搜索来了解触觉图形的深层位置时，需要可靠的主动机制来表示合成语音。开发了一种连接到USB的交互式触觉显示器。此外，触摸点，触摸滚动和触摸缩放功能实现到用户界面的显示器.评估实验进行实验，以评估所提出的系统的有效性。严重视力受损和蒙眼的参与者通过使用该系统识别了许多指南地图和插图。因此，有用的辅助设备，以接收非语言的内容在网络上的严重视力受损的解释。

Reception of non-verbal contents such as the figures and images in the Web is difficult for severe visually impaired persons. This study aimed to realize an idea to transform non-verbal information to spatio-temporal tactile image. Furthermore, synthesized speech presents, in connection with a deep position on the tactile representation. Obtained results are as follows.1. Design of Web algorithmSince endure the functions for the enlargement / reduction of tactile graphics in connection with same sound presentation, particular algorithm is needed. The Adobe Flash type of files is used to validate in the Web software.2. Development of interactive tactile displayReliable active mechanism is needed to represent synthesized speech, when intend to know a deep position of the tactile graphic by haptic search. An interactive tactile display developed which is connected to the USB. In addition, touch point, touch scroll and touch zooming functions are implemented to the display for user interface.3. Evaluation experimentExperiments performed to evaluate the effectiveness of proposed system. Severe visually impaired and blindfolded participants, recognized many guide maps and illustrations by use of the system. Thus usefulness for assistive device to the reception of non-verbal contents on the Web by severe visually impaired was explained.
