A small Braille display with Active Tactile Control (ATC) Braille technology was developed in association with the Handy Tech Company. With ATC technology text information can be read without pressing a scrolling button, as the system automatically shifts to the next line when the reading finger is detected at the end of the last word. This Braille display was connected to two compatible systems. The first is the TANIA (Tactile Acoustical Navigation and Information Assistant) navigation system, based on detailed maps, a movement sensor, and the Global Positioning System (GPS). The second is an object recognition system, which uses 3D environmental models, a movement sensor and stereo camera. Either system, or both in combination, provide information acoustically or in Braille. Blind and deafblind users report that the use of the portable ATC display technology combined with these systems represents an additional step toward increasing independent orientation and mobility.
