Physiotherapic Games Project

I'm computer science brazilian student and i working in a project that pretend to develop games in C# language using XNA framework, the Wiimote controller and speech recognition. The project is in the start yet but i have reach some success in the communication of the Wiimote controller and the PC, i've develop a software that simulate the pc mouse using the wiimote accelerometer, so we don't have to worry about the obstacles of the IR sensor, and don't neet a sensor bar too. The next pass is communicate the wii balance board with the PC, this will be the project of the next year. More information about the project will be posted later....
