Gesture detected by inertial sensor

In the wearable technology, inertial sensor has great significance in tracking the object movements. The paper focused on detecting the movement of users fingers based on the inertial sensor to give the control signal. Firstly, the attitude matrix, which represented the transformation relation of carrier coordinate system and the navigation coordinate system, was obtained. Secondly, the attitude matrix was expressed based on the quaternions. Thirdly, the angle of the finger gesture was processed by the attitude matrix to get the attitude angle. The experimental results showed the detection of the finger movement is effective.
