Equipment Operation by Motion Recognition with Wearable Wireless Acceleration Sensor
Hiroshi Tanaka, Ryo Kimura, Shigenori Ioroi · 2009
This paper proposes new system architecture for equipment operation based on the motion recognition using a 3-axis acceleration sensor. The small sensor is attached to the wrist with a band and is worn as a wearable device so as not to disturb body motion. The motion of the arm is detected by the acceleration sensor, and data are transmitted to the PC by Bluetooth signals. It has a wide detection range compared to video methods because the Bluetooth radio system has omni-directional characteristics. The data are analyzed using a DP matching method in the PC and the templates stored in advance are compared. Each template data correspond to the equipment operation. The IR signal is transmitted based on the results of matching and this signal operates the equipment. A television and a room light are selected for the system demonstration, and it is confirmed that turn on/off of each piece of equipment, changing channels and volume alternation can be performed through body motion.
