Design of human-computer interaction gesture operation based on STM32 and MPU6050

In order to improve the convenience of computer use, a human-computer interaction mode of gesture operation is proposed. With the main functions of collecting and processing user environment information and obtaining their own state, and with the characteristics of fast, convenient, attached and anytime, anywhere, a wearable gesture operated human-computer interaction device is designed. The system is composed of STM32F103 single chip microcomputer, six axis sensor mpu6050, Bluetooth hid module XM-04-HID-K, etc. the six axis sensor fixed on the back of the hand obtains the hand inclination angle in real time. The CPU determines the instructions to be executed according to the received data and converts the operation into instructions. All instructions are integrated in a specific packet format and sent to the upper computer through the Bluetooth hid module, The test shows that the mouse pointer can be controlled by the movement of the hand.
