This paper presents the realization of a character input system for disabled people using tooth-touch sound. The proposed system had several advantages, including low price, ease of handling, and reliability. First, we analyzed the characteristics of the tooth-touch sound, obtained using a bone conduction microphone. We utilized the tooth-touch sound as a control signal for the input device. For practical purposes, we developed a novel method for eliminating the voice signal and white noise. Finally, we designed a device using the FPGA (Field Programmable Gate Array) in practice and applied it to the character input system to confirm its usefulness. © 2008 Springer-Verlag Berlin Heidelberg.
