Turn off eye tracking calibration, keep eye tracking on

Re: "Turn off eye tracking calibration, keep eye tracking on"

"turning off eye tracking calibration - I need to turn this off for a client with a disability who is always moving around, how do I do this?"

Sorry no-one has answered your post so far, Am no expert in this area, yet your post deserves some response. (Those most expert are often those who use eye-tracking regularly themselves.)

Sorry I don't know whether eye-tracking calibration can be turned off, yet eye-tracking remain on.

We don't know whether yourclient uses iPad or iPhone, and whether the OS version is up-to-date or not.

Apple support's latest article for iPadOS 26 may have some tips:

Eg: Noticing a few things that may (or may not) provide more control:

✽ Recalibration begins automatically, yet can be manually started.

✽ You can change which corner of the screen is looked at to start it

✽ The dwell timer can complete before recalibration commences.

✽ Dwell Control can have the timer adjusted, + / -

or can be on or off.

Eg: says:

"Recalibrate Eye Tracking

If you change the position of your face or your iPad, Eye Tracking calibration automatically starts if recalibration is needed. You can also manually start Eye Tracking calibration.

1. Look at the top-left corner of your screen and hold your gaze steady.
2. The dwell pointer  appears and the dwell timer begins (the dwell pointer circle starts to fill). When the dwell timer finishes, Eye Tracking calibration starts.
3. Follow the onscreen instructions to calibrate Eye Tracking. As a dot appears in different locations around the screen, follow its movement with your eyes.

You can change which corner of the screen you need to look at to start recalibration or assign actions to other corners. See Set up Dwell Control.

Set options for Eye Tracking

You can set options for how the Eye Tracking pointer responds to your gaze.

1. Go to Settings  > Accessibility > Eye Tracking, then adjust any of the following:

• • Smoothing: Increase this value to make the movement of the pointer smoother. Or decrease this value to make the pointer more responsive.
  • Snap to Item: Have the Eye Tracking pointer automatically move to the item on the screen that’s closest to where you’re looking.
  • Zoom on Keyboard Keys: When you dwell on the keyboard, zoom in on the section of the keyboard you’re looking at. Dwell again on a key to tap it.
  • Auto-Hide: Show the Eye Tracking pointer when you hold your gaze steady for the amount of time specified. When your eyes are moving, the pointer automatically fades.
  • Dwell Control: Turn Dwell Control on or off. To adjust settings for Dwell Control, such as the default dwell action and the duration of the dwell timer, see Set up Dwell Control.
  • Show Face Guidance: Turn Show Face Guidance on or off to get help adjusting how you’re positioned.
