Abstract
An increasing number of studies have used technology to help blind people to integrate more fully into a global world. We present software to use mobile devices by blind users. The software considers a system of instant messenger to favor interaction of blind users with any other user connected to the network. Input/Output implementation modules were emphasized creating a 9-button virtual keyboard and associated Text-to-Speech technology (TTS). The virtual keyboard helps to write into the pocketPC without needing external devices, representing a real challenge for novice blind users. The TTS engine was adapted to blind users by adjusting the engine. Usability evaluation of these modules was iteratively applied to end-users. As a result, the integration of the designed modules into a communication system helped us to create a messenger system specially tailored to people with visual disabilities.
