TOOTH-TOUCH SOUND AND EXPIRATION SIGNAL DETECTION AND ITS APPLICATION IN A MOUSE INTERFACE DEVICE FOR DISABLED PERSONS - Realization of a Mouse Interface Device Driven by Biomedical Signals

Abstract

Presented is a mouse interface device for disabled persons using tooth-touch sound and expiration signals. It enables disabled persons to operate a personal computer easily using a mouse driven by their tooth-touch and expiration. A bone conduction microphone was used to detect the tooth-touch sound and the piezo film sensors to sense the expiration. Both sensors had superior features including being easy to handle, light weight, user-friendly, and inexpensive making the device practical as a mouse interface for disabled persons. First, we describe the novel method for detecting the tooth-touch sound in conjunction with Dyadic Wavelet Transform to improve the performance of tooth-touch sound detection. The device consists of sensor units that can sense the tooth-touch sound and the expiration signals, an individual adaptive circuit, and an output interface to connect directly with a mouse and Environmental Control System (ECS). Next, we designed the device using Hardware Description Language (VHDL) and realized a prototype of mouse interface with a Field Programmable Gate Array (FPGA) in practice. Finally, we confirmed the basic operation of the mouse.
