A hand-held, non-contact, address-setting remote control device of an LED lighting system is configured to allow a user to selectively assign addresses to LED lights of the system. The transformer assembly of the system can be programmed remotely using an application program (hereinafter an “app”) installed on a mobile device (e.g., an iPhone or Android phone). During operations, the transformer assembly uses the addresses that have been assigned to the LED lights to send commands to the LED lights to cause the LED lights to perform commands associated with the assigned addresses. The addresses of the LED lights can be easily changed using the hand-held, non-contact, address-setting remote control device, and the transformer assembly can be easily reprogrammed using the app. These features greatly improve the flexibility with which the LED lighting system can be programmed and controlled, which greatly improves usability for the installer and for the customer.

This project proposes a low-cost, universal, and purely local gesture control scheme for mobile phone screen projection games. Users only need to place their phones in a common stand and use the front camera to recognize left and right gestures and screen projection functions in real time. This allows users to control screen projection games (small games created based on these two gestures) without touching the screen while driving, achieving lightweight interaction between the driver and the car. Unlike existing solutions that rely on vehicle-grade cameras, this project is completely based on local computing power and does not upload any data, ensuring privacy and security without the need for vehicle reconstruction. Moreover, the project adds vibration compensation and smoothing filters to effectively solve the problem of users being unable to accurately control the screen with gestures in a bumpy car, as well as using screen projection technology to reduce eye strain and motion sickness caused by small screens. Currently, this project has been implemented on Android phones such as OPPO and Huawei, with preliminary adaptation tests underway.
