Towards Tangible Vision for the Visually Impaired through 2D Multiarray Braille Display.

Area of Science:

• Human-Computer Interaction
• Assistive Technology
• Multimedia Accessibility

Background:

• Previous research utilized Kinect v2 and haptic devices, but faced limitations in operational speed and object detail reconstruction.
• Existing 1D braille displays have limitations in representing complex media content efficiently.

Purpose of the Study:

• To develop a high-speed and accurate 2D multiarray braille display system for delivering multimedia content to visually impaired users.
• To overcome the limitations of previous methodologies in terms of speed and detail representation.

Main Methods:

• Development of a 2D multiarray braille display integrated with an electronic book translator application.
• Utilizing quantization and binarization techniques to represent illustrations and figures on braille displays.

Main Results:

• Achieved significantly faster operational speed compared to previous haptic device-based methods.
• Enabled the representation of considerably larger amounts of text content than 1D braille displays.
• Successfully represented illustrations and figures, enhancing multimedia accessibility.

Conclusions:

• The developed 2D multiarray braille display offers a more efficient and accurate method for delivering multimedia content to the visually impaired.
• This approach enhances mobility and provides a superior representation of media content contours.
• The system significantly improves accessibility to text, illustrations, and figures for visually impaired users.
