Abstract
The selection of this research topic is deeply motivated by the real-world application needs and technological progress. In the background of the rapid rise of the Internet of Things and smart home industry, gesture recognition, as a direct and user-friendly interaction means, its market demand is increasing. At the same time, the high performance of STM 32 series MCCM and the accurate monitoring capability of MPU6050 sensor provide a technical basis for creating an efficient gesture recognition system. As a hot topic of human-computer interaction research, gesture recognition technology has also attracted the attention of many researchers. Therefore, this project is committed to the design and implementation of a gesture recognition system based on STM 32, aiming to explore and realize the algorithm of gesture recognition, hardware design and its application in different scenarios, in order to meet the application needs of the market and promote the further development of related technologies. In addition, the study also reflects the researchers' deep interest in embedded systems, sensing technology, and human-computer interaction, aiming to enhance the mastery and application of these technologies through specific engineering practices.
This paper plans and successfully develops a gesture recognition system based on STM 32, which is remarkable in terms of innovation and practicality. The system consists of the main control unit and the subordinate unit, which is responsible for data reception and interface display, while the subordinate unit is specially responsible for gesture detection and data upload. The main control unit has a built-in Bluetooth communication module and a LCD1602 LCD screen, which can receive the gesture information transmitted by the subordinate unit through Bluetooth technology, and display these information on the display screen in real time. The subordinate unit is equipped with a Bluetooth communication module and a MPU6050 sensor that can accurately capture and recognize gestures in multiple directions, and then transmit the information to the main control unit via Bluetooth. Through the cooperation of the master and slave units, the system can accurately and efficiently complete the recognition of gestures and information display. This study not only confirms the application prospect of STM 32 in gesture recognition, but also provides a valuable reference for the future design of intelligent interaction systems.
