Submitted to ITS 2010. This interactive event presents a pressure sensitive chair constructed out of Wii Fit game controller boards. During this even, we demonstrate how to arrange the boards to detect seat and back pressure, configure a PC to receive a bluetooth datastream from the boards, and modify the power supply of the boards to increase uptime and reliability. We claim that the pressure sensitive chair so constructed is highly suitable for recovering posture information from a student interacting with an ITS.
