Communicating with computer involves use of touch screens, wireless/wired mouse along with keyboards. In this paper, we propose a Â¿Human Computer Interfacing DeviceÂ¿ mapping Hand Gestures, most intuitive communication gesture, to communicate with computers, robots and other household electronic devices. Developments in field of communication have enabled computer commands being executed using hand gestures. This proposed novel solution achieves effective interaction with Internet giving quality feedback, intuitive control with complete mobility. Simple inertial navigation sensor like an accelerometer is utilized to get dynamic/static profile of movement to navigate the mouse or gyroscope to rotate 3-D virtual objects. Accelerometer profiles are converted into wireless interactivity. The device involves non-tactile interaction with computer screen where mouse pointer reacts to and manipulates screen content in accordance with hand gestures. The applications envisioned: interaction using gesture technology for effective communication empowering physically challenged to interact with computers including 3-D graphic interactions and simulations.
