This paper presents the realization of a hands-free man-machine interface using tooth-touch sound. The proposed device has several advantages,including low price, ease of handling, and reliability. It may be used as an Environmental Control System (ECS) and communication aid for disabled persons. We analyzed the characteristics of the tooth-touch sound, obtained using a bone conduction microphone. We then designed the device using VHDL(Hardware Description Language) and a simulation of the FPGA (Field Programmable Device) in practice. We applied our device to the ECS to demonstrate its usefulness and evaluate its performance. The results confirmed that the proposed device had superior features to comparable devices, such as those utilizing voice control or eye blinks, chin operated control sticks, mouth sticks, or a brain computer interface (BCI) for severely disable persons
