Abstract
In order to understand the cognition of Taiwanese visually impaired people who use an IT-based touch panel, a prototype named the Chinese Braille Simulator is developed. This prototype uses braille simulation software, speech synthesis and a touch panel to allow people with impaired vision to send and receive short messages. The TAM and content analysis are used, and our findings show that visually impaired people find the IT-based touch panel both interesting and useful. We conclude that current technology developers should focus on a braille interface in IT-based touch panels for the visually impaired. Short-, mid- and long-term recommendations for practitioners are also made.

1.1 Briefing of the CBS
When the CBS is started (Home Screen), four functional main screens are displayed: Receive (F1 Screen), Send (F2 Screen), Draft Box (F3 Screen) and Send-back (F4 Screen). The system gives a prompt sound to indicate the functions of the CBS software after the user touches the screen and then continues on to the other sub-function as well.
