Bio-Metric Authentication of an User using Hand Gesture Recognition

This paper presents an authentication of a user based on gesture recognition algorithm using accelerometer. It is very challenging task to recognize user action and reaction corresponding to that in real time by designing a dynamic gesture interface system. Physical movements of face, fingers, hands or body with respect to environment action is referred as Gesture. For applications like sign language, virtual reality and remote control gestural interfaces are developed using gesture recognition and motion tracking techniques. In this paper, we are designing a hardware module consisting of a triaxial accelerometer and microcontroller transmission module to sense the hand gesture and collect the same. User can use this hardware module to draw any kind of gesture. Personal computer receives the hand motions transmitted by the transmitter that is connected to accelerometer. Using the proposed algorithm we are able to authenticate the user effectively. For continuous reaction gesture is recognized and estimates variations in gestures in our module. Our work has been found to provide better accuracy and validation result compared to existing works.
