Good project. Have you invited any visionally disabled people to do a real test of your system? If user experience is good and there is no such portable device in the market, I think it may be commercialized?

Thank you very much for your support. We have been keeping in touch with the Hong Kong Blind Union throughout the project from prototype stage. We are contacting them to provide update on our final product and hopefully our product can reach a wider base of potential target users.

Does your device only allow the user to read one letter at a time? If this is the case. Can blind people read books through your device?

Thank you for your question. As the visually impaired touches paper-embossed tactile Braille characters one by one by swiping their fingers through the text, our single cell refreshable Braille display refreshes the character by raising and lowering the pins. Thus, the device serves the same function as ordinary paper-based Braille characters. The single-cell feature is an advantage as the user need not to swipe through the characters, instead they only need to rest their finger on the device. Hence, increase users’ comfortability.
