NavEye – Hands-free scrolling using eye tracking

Summary: NavEye converts your webcam into a hands-free scrolling device by detecting eye closures to scroll up or down. It processes all data locally to ensure privacy and uses a custom physics engine for smooth scrolling. The tool is free, open-source, and compatible with Windows and macOS.

What it does

NavEye enables scrolling by closing the left eye to scroll down and the right eye to scroll up, using webcam-based eye tracking. It applies a custom physics engine to provide natural acceleration during scrolling.

Who it's for

It is designed for users who want to avoid repetitive mouse use while coding, reading, or browsing, maintaining flow without interrupting hand activity.

Why it matters

NavEye addresses mouse fatigue by allowing hands-free scrolling with full local processing to protect user privacy.
