Vertical head motion scrolls the page while horizontal motion switches tabs, giving you a hands-free way to navigate Chrome.
The head-tracking model runs in your browser against the webcam feed, so detection happens locally rather than on a remote server.
Neckium notices when your sitting posture drifts and sends a notification prompting you to straighten up.
It also flags prolonged sitting, encouraging regular movement breaks during long work sessions.
The extension is roughly 1.5 MB and its developer states that it does not collect or sell your data.
Neckium is a browser extension that rethinks how you interact with Chrome. Instead of reaching for the mouse or keyboard for every small action, you can tilt or turn your head and let the extension do the work. It runs a TensorFlow.js model against your webcam feed locally, detecting head orientation and mapping movements to common browsing gestures — scroll a page by moving your head vertically, or jump between tabs by moving it horizontally.
Beyond hands-free navigation, Neckium doubles as a quiet ergonomics coach. It watches for poor sitting posture and long uninterrupted sitting sessions, then surfaces gentle notifications encouraging you to adjust your position or take a break. This makes it useful both for people who want reduced-touch browsing and for desk workers trying to build healthier habits.
The extension is small (around 1.5 MB), free to install, and positions itself as a developer-friendly experiment — the publisher discloses that no user data is collected or sold. It is best suited to Chrome desktop users with a working webcam who are curious about alternative input methods and posture awareness.
People who struggle with mouse or keyboard input can scroll and switch tabs using only head movements.
Remote and office workers can receive nudges to correct slouching and stand up periodically.
Anyone curious about TensorFlow.js vision models can see a working example of real-time head tracking in a browser extension.
