A Hands-Free Interface Demo using MediaPipe. Control the UI with your hand!
MediaPipe is Google's open-source framework for building fast, cross-platform machine learning pipelines. It offers ready-to-use solutions for tasks like hand tracking and face detection that run entirely in the browser, making advanced AI accessible to web developers.
The Hand Landmarker model detects 21 key points on your hand in real-time. We use the 'x' coordinate of your index finger to control the slider and the 'y' coordinate to scroll. For the button, we calculate the distance between your thumb and index finger to detect a "pinch" gesture.
This technology opens up new frontiers for web accessibility, allowing users with motor impairments to navigate the web. It also has exciting applications in augmented reality, gaming, and creating more intuitive, natural user interfaces for everyone.
