Hello, thank you for reaching out to Microsoft Q&A.
May I please know the make and model of your eye-tracking device?
Unlike regular USB cameras, these may require additional drivers to work on your computer. Please refer to the documentation or the manufacturer’s website to see if any drivers need to be installed additionally for the tracking device to work.
Alternatively,
- You can open the Device Manager.
- Expand the arrow next to cameras.
- Right-click your integrated camera device driver and select Disable Device.
- Doing this will enable the eye tracking device camera.
See if it works.
