| Research Abstract |
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 algorithm
Since 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 display
Reliable 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 experiment
Experiments 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.
