Eye tracking with the webcam you already have.

GazeLynx estimates where you are looking on your screen. No headset, no extra hardware, and nothing leaves your computer.

See it in action How it works

No headset. No tracking bar. No extra hardware. Just the camera already sitting on top of your monitor, and a very careful piece of software behind it.

Four steps. Nothing to buy.

  1. Set up

    Use the webcam you already have and the monitor it points at. Nothing to buy, nothing to wear.

  2. Calibrate

    A short guided sequence of targets adapts the system to you, your face and your desk.

  3. Track

    Your gaze point follows the screen continuously, with an optional marker drawn over the desktop.

  4. Review

    Record a session locally and look back at it later instead of watching it live.

What you need.

Any webcam

Built-in or USB. The one you already have will do.

One screen

The monitor your camera sits on.

Some light

It's an eye tracker, not night vision.

Inside the app.

A desktop app that stays out of the way: calibrate, then let it run while you work.

Interface mockups. The app is in development and will change.

Your face stays home.

Eye tracking means a camera pointed at you. So the rule is simple: what the camera sees never leaves your computer.

  • No account

    Nothing to sign up for and nothing to log into.

  • Video stays on your computer

    Camera frames are processed on the spot and never uploaded anywhere.

  • Camera on only while tracking

    It opens when you start and closes when you stop.

  • Your recordings, your disk

    Sessions you record are saved locally. Keep them or delete them.

Built the honest way.

Local by design

Everything runs on the computer in front of you. The camera opens only when you start tracking, and no video ever leaves the machine.

Measured, not claimed

Accuracy depends on the camera, the light, the display and the person. Instead of one shiny number, GazeLynx checks itself against targets it hasn't seen and tells you what it measured.

Deliberately narrow

One person, one monitor, one camera. A small scope, so the core problem gets solved properly before anything is built on top.

Where it could go.

Four directions, four small demos. Your cursor plays the part of your gaze.

Accessibility

Press without pressing.

Rest your gaze on a control for a moment and it activates. Interaction that doesn't depend on a hand.

Try it: hover a button and wait.

Slow Orbit Night Shift

Human–computer interaction

Interfaces that know where you're reading.

Text that keeps your place, pages that move on when your eyes reach the end, and notifications that wait until you look up.

Try it: read with your cursor. At the bottom edge the text scrolls by itself.

Your eyes don't glide across a line. They jump, pause and jump again, and almost everything you take in arrives during the pauses.

The pauses are short, and you notice none of them. To you, reading feels smooth and continuous.

Short, predictable words are often skipped altogether. Long or unexpected ones tend to get a longer look.

Every so often the eyes jump back to check something again, usually without you deciding to.

An interface that can see this can keep your place, notice where you slowed down, and wait until you have finished before it interrupts.

That's the whole idea: software that pays attention to your attention.

Research

A lab recording, without the lab.

Record a session and replay it later: where the eyes went, in what order, and for how long.

Try it: drag the timeline.

Interface analytics

See what really gets looked at.

Clicks tell you what people did. Gaze tells you what they looked at on the way: what they read, what they skipped, and what pulled them in.

All demos on this page are illustrations, not real measurement data.

Currently in development.

GazeLynx is an active research and engineering effort. The system is being built and evaluated, and it keeps changing as the work goes on. There is no public release yet.
