Abstract

Aims: The article focusses on the working principle of devising a display board and introduction to a working model of a single unit of a novel prototype of a computer display board for blind people.

Objectives: The developed prototype is aimed at converting a conventional computer screen to a braille screen based tactile display board. The arrangement will enable the blind people to accesses soft data as a converted braille language text. In addition, the position of the write-up will also be recognizable by the blind.

Methods: The system employs six number of micro linear actuators providing haptics feedback.

Results: The ABCD display unit was tested with the blind and was found to be received well by the community. According to the survey, this raised dot mechanism is very effective for blind communication.

Keywords: Arranged blind computer display board, applications of braille technology, gadget for visually impaired, haptic advancement, tactile display, actuators.
