A Contact-Free Human-Computer Interaction Interface Based on Embedded System

In this paper, a contact-free human-computer interaction interface is developed. The system recognizes the hand gestures from the user and transmits corresponding control signals to the end-user side. Subsequently, the end-user side manipulates cursor movements or clicks based on the received control signals. To ensure the operability on the embedded system development board, the system adopts low-complexity methods and integrates an external vision processing unit. The experiment results demonstrate the successful implementation of the system on Raspberry Pi 4.
