A cutting edge technology that combines the use of a tactile (raised line) graphic, a touch screen or drawing pad, and computer software. A file is loaded into the computer that has commentary associated with different areas of the touch screen. The tactile graphic has raised lines that represent or lead to those areas that have commentary in the file. Speech synthesis software voices the commentary when pressure is exerted on the various areas of the touch screen.
This technology is still in development but has shown excellent prototype uses for a variety of disabilities.
