🎮 Autonomous Controller Charging via Browser

Developer Ray Foss has introduced Triton Auto-Charge Vision Tracker — a web application for the automatic charging of a Steam controller (Triton 2026 model). The system uses OpenCV.js via a webcam to track the coordinates of the device and the magnetic charging station. Navigation works through WebHID, sending tactile pulses to the controller's actuators to physically "guide" it toward the base.

🌍 A demonstration of the capabilities of combining WebHID and computer vision (OpenCV.js) in the browser to control physical devices without installing heavy software.

👤 A fun and technically advanced example of how AI and CV can solve practical everyday tasks.
