Improved Speech Assisted Learning Device for Blind Students
Published: Jun 24, 2007
Exceptional Teaching and Touch Graphics Inc., with the funding from National Science Foundation, plan to introduce SAL2, part of the Talking Tactile Tablet (TTT).
This system, unlike its predecessor the Speech Assisted Learning (SAL) device, uses a more powerful software that allows visually impaired students and adults to work on math problems, geography, or even solving crossword puzzles without the help of a human tutor.
