How to make a webcam to work?

Here's how you can tackle issues with webcam access.


RealEye is tested and works with the following hardware and software setup:

  • Google Chrome web browser.
  • PC with Microsoft Windows 10 or Mac (Macbook, iMac) with MacOS.
  • Laptop intergrated webcam or USB webcam.
  • RealEye DOES NOT allow running eye-tracking test on mobile device (smartphone).
  • Required screen resolution is 1024x968 pixels or more. Only horizontal screen orientations is supported. Please make sure to NOT use any zoom - page scaling should be 100% (press CTRL+0 in Chrome).

If you get "Enable webcam access to begin" message when you're running eye-tracking test:

  1. Make sure your webcam is connected and working. You can check it with any video chat software or system applications like the "Camera" app on Microsoft Windows or "Photo Booth" on MacOS.
  2. Make sure you have enabled camera access in your operating system settings. For Microsoft Windows read this. For MacOS read this.
  3. Make sure you've enabled camera access in Google Chrome - read this.
  4. Some Google Chrome extensions may still block webcam access, so we recommend running the test in incognito window.
  5. Make sure no other software is using the webcam. When you are performing an eye-tracking test, video conference is possible, but only if it's run in browser. Read more here.
  6. If you have Windows N Edition, install Media Feature Pack. Read how to do this here.
  7. Running eye-tracking test won't work on the old version of Edge browser, it only works on the latest Edge version based on Chromium.
  8. Make sure you have at least 4 GB of RAM.

If you're still having issues with accessing the webcam, contact us using chat or email (contact@realeye.io).
