Thanks to advances in technology, there are more sophisticated visual impairment aids available for the blind. A new tactile system called Hamsa Touch uses electronic pulses to let visually impaired people feel what's on mobile and computer screens.
The braille-like device from Japanese researchers from the University of Electro-Communications combines the built-in camera function in smartphones with an electronic tactile display. By converting images into pulses, the visual impairment aids allow the blind to feel what's on screen. The prototype uses over 500 photo sensors, each of which correlates to its own electrode.
The Hamsa Touch still has a long way to go before it is ready. The team is working on performing user studies with blind people to receive feedback and figure out where improvements can be implemented.
