What is it about?
Braille displays, designed for allowing the visually impaired to read books/contents through a refreshable display is a highly effective and important quality of life addition for any such person. However, the high cost of such displays prevents mass use of such technology. We have designed what can be called the first few steps of possibly a commercially available affordable Braille display. Using a mechanically simple arrangement called cam and follower, the braille pins are moved up and down using a controller system that is coded to output the desired braille code.

Why is it important?
Our design is mechanically simple, modular and easily mass producible with basic manufacturing practices leading to a overall affordable display that can be used by the mainstream people in future.
Perspectives
I hope this article will raise awareness for the mass people about the expensive nature of currently commercially available displays. Working on this project and article was a very satisfying experience and has allowed me to learn various things in the process.
