In this paper, we proposed a real-time education assistive technology system based on haptic display to improve education environment of total blindness people. The proposed system consist of a lecture and writing S/W for educator and a previously developed haptic display H/W for total blindness people. The one has the major function which is quickly and easily writing to the education data, that will be provided to total blindness people, through familiar UI, the other has the major function which print out the tactile information about the education data. The result of implementing system not only provides a similar result using existing braille instrument and printer, but shows that it is effective performance and functionality because it can print out the education data in real time.
This paper presents two methodologies for delivering multimedia content to visually impaired people with the use of a haptic device and braille display. Based on our previous research, the research using Kinect v2 and haptic device with 2D+ (RGB frame with depth) data has the limitations of slower operational speed while reconstructing object details. Thus, this study focuses on the development of 2D multiarray braille display using an electronic book translator application because of its accuracy and high speed. This approach provides mobility and uses 2D multiarray braille display to represent media content contour more efficiently. In conclusion, this study achieves the representation of considerably massive text content compared to previous 1D braille displays. Besides, it also represents illustrations and figures to braille displays through quantization and binarization.
