Design of User Identification Interactive Hardware Modules
摘要
This paper introduces an interactive hardware system built with the ESP32 chip as its core control unit. The system is designed to integrate and modularize commonly utilized interaction methods in interactive devices, simplifying the process for designers to implement these mechanisms. It incorporates a range of advanced components, including a high-definition camera module, microwave radar ranging sensor, high-precision gyroscope, pressure-sensitive sensor, and sound detection elements. On the software side, the system’s functional logic and interaction workflows have been meticulously designed, resulting in a highly integrated platform for perception and interaction. This hardware system efficiently implements diverse interaction detection and response mechanisms between users and images, including distance and azimuth perception, touch and pressure recognition, posture recognition, and gesture recognition. Specifically, user orientation detection utilizes Bluetooth modules and microwave radar modules to measure the distance and angle between users and devices. User trigger detection is divided into two components: contact detection and pressure detection, which are implemented through a touchscreen and a resistive thin-film pressure sensor. User posture detection involves connecting to and reading gyroscope data to track changes in the user's body posture. User gesture detection is achieved via an external gesture recognition module to identify gesture actions. This interactive hardware system demonstrates deep cross-domain integration and technological innovation, offering a novel solution for human-computer interaction design.
