Accuracy over distance

Recommended Posts

Is there a more detailed explanation of the eye tracking accuracy than what is stated on Tobii's site for the Vive Pro eye please?

https://vr.tobii.com/products/htc-vive-pro-eye/

It says 0.1deg - 1.1deg, however it's unclear whether this means

  • +/- 0.1 degree min to +/- 1.1 degree max (making full range 0.2deg - 2.2deg)
  • +/- 0.1 degree min to +/- 1.1 degree max (making full range 0.1deg - 1.1deg)
  • somethng else

We are looking at understanding accuracy over distance so would like to understand what this means please

If anyone from Vive with experience in this area could chip in it would be most appreciated. We're trying to do some work where understanding this is very important in working with the data from the Vive Pro Eye. Thanks!

Accuracy is 0.5°~1.1° within FOV 20°, not related to distance. Eye surgery, eye disease, heavy makeup, and high myopia may affect eye tracking performance.
