Open-source local webcam hand-tracked mouse/gesture control
PawVis is an innovative open-source tool that transforms your Mac’s webcam into a gesture-controlled mouse interface, eliminating the need for additional hardware. By leveraging computer vision, it tracks your hand movements, allowing you to navigate your cursor, click, and scroll through simple gestures like raising your hand, dipping a finger, or folding two fingers. This makes it especially appealing to users seeking a touchless, more natural interaction with their computers, whether for accessibility, productivity, or just a futuristic experience. Its open-source nature invites customization, enabling users to map gestures to specific actions, window management, or commands suited to their workflow. Additionally, PawVis offers optional voice control and the integration of AI models like Codex or Claude Code for automating complex tasks, making it a versatile tool for developers and power users alike. Everything runs locally on the device, ensuring privacy and security, while being completely free to use.
