In order to enhance the interactivity of human-computer interaction and the controllability of remote control operation, a hand gesture detection system based on the magnetic field sensors and micro accelerometer was designed and implemented.Vsing coordinate transformation theory,the roll angle and pitch angle of attitude were solved through the magnetic field sensor data. And the combined with azimuthal xolved by magnetic field sensor data, the noise and the temperature drift of the sensors, as well as the interference of magnetic field sensors coming from the external magnetic field were compensated. The experimental results show that, this system can accurately measure hand gestures.
