Abstract
An apparatus for instantaneously translating sign language in to voice and video is introduced. The present invention uses accelerometer sensors to compute the position and movement of each finger, thereby instantaneously determining the posture of the hand. The location of fingers with respect to body is accurately determined by placing RFID tags at different parts of the body while a single RFID reader is placed on the index finger. Data from accelerometer sensors and RFID reader are multiplexed and sent wirelessly via a controller to a laptop processor where ultimate conversion of sign language to text/voice is achieved. Further, various characteristics of sign language comprising hand position, hand posture, hand orientation and hand movement are detected based on the accelerometer data and RFID data.
