New Concepts of PC Interaction for Blind Users Based on Braille Displays with ATC Technology (Active Tactile Control)
Braille presented as a combination of raised dots is a very important way of accessing information for blind computer users offering crucial advantages compared to speech output. The ATC (Active Tactile Control) technology allows new PC interactions based on detecting the tactile reading position in real-time on a Braille display. Reading position sensitive assistant functions and context depended controls, like task overview and Braille frames, are introduced.
