Aiming at the problem of teachers need to holding the laser pointer remote PowerPoint slide page up or down during the classroom teaching, this thesis presents a method to control the PowerPoint slide page by the somatosensory bracelet, and designs somatosensory bracelet teaching device based on MPU6050 sensor, which adopts the structure of wireless data transmission control system including the wireless somatosensory bracelet and the teaching receiver. The research focuses on the algorithm of gesture definition, gesture signal sensing and preprocessing, gesture feature extraction, and verifies the validity and accuracy of the algorithm through the design and test. Experimental results show that the system can effectively identify the gestures to the left or right, and reliably control PPT page up or down to achieve the design effects.
