Ridac / smart home system


Ridac is a technical ring to manage all the domestic appliance control. Users first pin point out the target appliance (TA), then use predefine hand gestures to control it. We apply ultrasonic wave to locate the TA that users are referring to. Once the connection between Ridac and TA is confirmed, the hand gesture recognition system would send corresponding control signal such like turn on, turn off, volume up, and volume down. Even more, Ridac is charging free and battery free because of low power system design and adopting Peltier tiles for power supply. Ridac simplifies our life only through a few gestures.
