In this paper we present a sensor glove capable of converting hand gestures to audio wirelessly using Indian Sign Language (ISL). The key components of the device are strain sensors made of inexpensive and conductive material sheet, ‘Velostat’. Velostat sheet, which is made of a film surfaced with carbon particles used for anti-static package of electronic parts. Resistance in the sensors varies according to the strain of the film. The sheet is a polymeric foil (polyolefins) impregnated with carbon black to make it electrically conductive. These sensors are integrated on the glove along with IR (infrared) sensors mounted on each finger and Gyroscope on each hand to record the hand movements. A wearable electronic module consisting of a STM32 microcontroller and a Bluetooth module is mounted on the glove. In concert with sensors, glove is able to translate all 26 alphabets and general English language sentence gestures of the ISL into English words and corresponding text. Lastly, data received from the glove is converted into an audio. This application suggests new ways in which stretchable and wearable electronics can minimize communication gap between hearing impaired and outer world to ensure effective communication.
