Students from the Applied Physics Department of the University of Karachi have developed a machine called ‘Braille Display,’ which lets blind people send and read text messages. According to a student, they’ve been working on this project for over one year and at the moment the device can only process four-letter words but they are working to improve the technology.
The apparatus which is currently in the process of development converts the received text into braille (raised letters), and blind people can read it by touching the display. People with visual impairment can also write their messages in the same way. It works like a braille but has digital apps as well.
