Temporal validation Varjo #47

Open timjzee opened 7 months ago

Unfortunately Varjo doesn't provide timestamps from the headset internal clock through the Unreal interface. However, if our application runs at a steady 90Hz, and we see that every frame we get unique eye gaze values, then we know that at least we have an eye tracking sampling rate equal or grater than 90 Hz.

This means that as long as we do not need to know the exact latency, we can use the Varjo headset for eyetracking.

BTW, perhaps there is a way to simultaneously record eye tracking data within Varjo Base and Unreal and then compare the measurements?
