Wireless Non-Line-Of-Sight Electronic Automation Using Sonar Based Gesture Detection For Human Machine Interaction

Abstract

In a world where wireless is not just a technology but a trendsetter, imagine how lives would change if only one can control electronic appliances with just a flick of the finger or wave of a hand. The primary objective of the proposed idea is to wirelessly control
home appliances with simple hand movements or gestures by overcoming the line of sight constraint. In this, a pair of RF transmitter and receiver coupled with ultrasonic detectors for gesture recognition is used. A control unit integrated with the receiver is used to actuate the electronic appliance depending on the gesture recorded. With the presented interface, users can control appliances like TV, fan, lightings, air conditioners and thermostats. This technology is devoid of privacy issues as in the case of cameras that use image processing and also proves to be much more cost efficient than existing system.
