Development of an Electronic Glove with Voice Output for Finger Posture Recognition

Abstract

This project is to develop an electronic glove which can translate hand posture in Malaysian Sign Language into spoken words. The glove is built to help deaf, blind and non-vocal persons to communicate with normal people like us. Furthermore, this project can be divided into 4 main parts. First is the sensing part which consists of flex sensor and accelerometer, they are sewn on the electronic glove to detect the motion of finger. Second, the 555 timer circuit is used to convert the analog voltage to frequency. Then, part three consists of microcontroller, it is used to analyze the input signal, as a frequency counter and as a controller. Finally, the result would be output as spoken words via a small speaker. Some simulation and lab testing of the flex sensor have been carried out. The flex sensor is reliable to detect finger posture.
