Eye tracking on a Mac: how the pieces fit, and how to write with it

By · Published

On a Mac, eye tracking comes from a separate eye tracker whose own software moves the pointer. macOS then supplies the rest: Dwell clicks when your gaze rests on something, and the Accessibility Keyboard types. Apple's Mac User Guide for macOS 27, read October 9, 2026, lists no built-in eye tracking for the Mac, and its Dwell page describes Dwell as the way to perform mouse actions with eye- or head-tracking technology. Without a tracker, head pointer moves the pointer with the Mac's own camera.

I make YapToText, a free dictation app for the Mac, and InputConfig, a free app that turns any button, switch or controller into keys and clicks. I built both because my own hands do not work well. I have not tested an eye tracker with either app, and I name none here.

What does what

From Apple's Mac User Guide pages for Dwell, head pointer and the Accessibility Keyboard, read October 9, 2026.

Set up Dwell for an eye tracker

  1. Set up the tracker with its own software until it moves the Mac's pointer.
  2. Open System Settings, Accessibility, Keyboard, and turn on Accessibility Keyboard.
  3. Click the info button next to it, go to Dwell, and turn on the Dwell toolbar in panels, the Dwell menu in the menu bar, or both.
  4. Pick a dwell action such as Left Click, then rest your gaze on the target for the dwell time.

Dwell actions are Left Click, Double Click, Right Click, Drag & Drop, Scroll Menu, an Options Menu for one-time actions, and Pause. The Accessibility Keyboard and Dwell guide covers each one, plus dwell corners.

No tracker: head pointer uses the camera

Head pointer moves the pointer as you turn your face or move your head, using the camera built into or connected to the Mac. Turn it on in System Settings, Accessibility, Pointer Control, and click with a facial expression, a key or a switch through Alternate pointer actions. The head pointer guide has the setup and fixes. It pairs with Dwell the same way a tracker does.

Typing letter by letter is the slow part

Each key on the Accessibility Keyboard is a dwell. Word suggestions and automatic spaces help, and a password or a code should stay on the keys. For a message or a page, one dwell to start a dictation replaces hundreds of dwells on letters.

Start a dictation with your eyes

Two ways, both built from things the pointer can reach:

  • Dwell on Start Dictation. Dwell on the capybara in the menu bar, then on Start Dictation at the top of its panel. It does the same job as YapToText's dictation key. Turn on Auto-stop after silence, in the Recording card of the Dictation page, and the dictation ends after 0.5 to 5 seconds of quiet, so you never aim at a stop button.
  • Look into a corner. InputConfig's screen regions fire while the pointer is inside an area of the display, and InputConfig's page says anything that moves the pointer can drive them, an eye tracker included. Draw a small region in a corner you do not use and give it the Keyboard Key Right Command. Looking into the corner and away presses and releases the key, which YapToText reads as a tap: start, then the same again to stop. A corner needs no dwell time, because the screen edge holds the pointer for you.
YapToText's menu bar panel: Start Dictation, mode and microphone pickers, Transcribe file, Regenerate and Insert last.
Figure 1. Dwell on the capybara, then on Start Dictation. The first button in the panel does the same job as the dictation key.

The corner works by how both apps are built: InputConfig sends the key, and YapToText counts a press with no other key as a tap. I have not tested it with an eye tracker. Draw the region small and tight to the edge, because gaze wanders more than a hand does, and see InputConfig's screen regions page to tune it.

Pause Dwell while you talk

Your eyes keep moving while you speak, and Dwell keeps clicking wherever they rest. Choose Pause in the Dwell toolbar before you talk, and dwell on any dwell action to resume. YapToText's floating panel has pause, stop and insert, and cancel buttons, so a dictation can end from a dwell too.

Fix what you said without aiming

Right after the words land, make your next dictation one exact phrase within 30 seconds: scratch that takes it back, and replace X with Y swaps one word. For bigger changes, dwell to select the text, then use Regenerate in the menu bar panel, which rewrites a selection as any mode or with a one-shot action such as Make Concise.

The short version

  • Pointer. An eye tracker's own software, or head pointer with the Mac's camera.
  • Clicks. Dwell, on the Accessibility Keyboard's toolbar.
  • Writing. Dwell on Start Dictation, or look into a corner that InputConfig turns into Right Command.
  • What is tested. Apple's steps are Apple's. No eye tracker has been tested with YapToText or the corner handoff.

If you use an eye tracker with a Mac and something here is wrong, open an issue on GitHub. Every one gets read.

Questions

Does a Mac have built-in eye tracking?

Apple's Mac User Guide for macOS 27 lists none. A separate eye tracker moves the pointer, and Dwell, built into macOS, does the clicking.

Can I use a MacBook with my eyes?

With an eye tracker whose software moves the pointer, yes: Dwell clicks, the Accessibility Keyboard types, and dictation writes.

What is the difference between head pointer and eye tracking on a Mac?

Head pointer is built in and follows your head through the camera. Eye tracking needs a separate tracker that follows your gaze.

How do I type with eye tracking on a Mac?

Dwell on keys of the Accessibility Keyboard for short text, and start a dictation for anything longer.
