Hi @michaelli, thanks for getting in touch. I have asked around our development team and I’m afraid that we do not currently have a solution to generate a heatmap based on eye tracking data for VR. My only thought is that you could ask in the Pico SDK forum as well and perhaps another user has posted there?
It’s of course a very niche request, so you may have to develop your own application or possibly source another person (via fiver, upwork, etc) to develop it for you.
Best of luck and do let us know how you get on. Best Wishes.
