New type electromagnetic drive for Braille screen

The graphical interfaces based on visual representation and direct manipulation of objects made the adequate use of computers quite difficult for people with reduced sight. Within the European Union, the problem with the access of blind people to computer resources is quite pressing. The main scientific aim here is: a concept for development, design and manufacture prototype of combined tactile-voice interface facilitating and allowing visually impaired people work with computers regardless of the user interface or operation system and oriented to graphical surfaces. Static force characteristics of recently developed permanent magnet linear actuator for driving a needle in Braille screen are presented.
