Abstract: Hand Gesture Recognition is popular concept that has grown its wide roots in the field of technology. Hand Gesture Recognition is being used in various applications, in these one of the major is interpreting of sign language as voice or text using Sensor Glove. This makes use of various sensors such flex sensors, contact sensors and 3 axis accelerometer for making glove, that sends readings recorded by the sensors to the microcontroller that computes these values and generates speech(using voice module) or text(using LCD). Various methods have been implemented to recognise various sign languages for helping the speech impaired. Realization of this application allows speech impaired people to interact with other normal people using the same generic sign language they use to interact, with ease and confidence.
Keywords: Sign LanguageRecognition, Flex Sensors, Contact Sensor, 3-axis Accelerometer, microcontroller.
