Breakthrough on touch screen for the blind

Scientists at the Polytechnic University of Lausanne (EPFL), Switzerland, have invented a new generation of touchscreens that allow users to feel by touching their fingers and screen. form.

This invention allows for a great deal of support for visually impaired people in accessing information and communication technologies.

Yves Perriard, research manager, explained that the technology is in the testing phase, is expected to be perfected and applied in the design of telephones, computers and automatic teller machines.

The new technology helps the user feel more focused on the operation, and in particular makes it easier for visually impaired people to access information and communication equipment.

To create a sense for the next generation of touchscreen users, EPFL scientists use a material that allows vibration to be generated when the voltage is applied to the material. This material will expand itself and quickly return to its original state.

With this process, new generation touchscreens have created a real revolution in communication that helps the user to be heard, seen and felt.

New technology is still being developed and developed by scientists.
