Getting Eyetracking data (HTC VIVE PRO EYE)

Question

Hello,

I’m currently working on a project. In this project, I’d like to track and record the eyetracking data (the user’s gaze movements) in VR using VIVE Eye Pro. I have no clue even on where to start.

Could anyone tell me anything about that please? I know that Tobii (the eyetracker built in HTC VIVE PRO) provides an anlytical software that can do what I want to do but at the cost of more than 8000 dollars… So, this option is not for me.

Thanks!

Answer 1

Have you taken a look at VIVE SRanipal SDK?

You can find instruction on how to install it here:

Answer 2

@Wolfie Did you manage to put something together? I would be interested in how you solved this. I’ve found a method for calculating the gaze position (on screen/camera). So if you’re still looking for the answer, just let me know.

I have successfully obtained eye-tracking data, but I would like to utilize this data to reconstruct the eye movement trajectory. Is there anyone who can help me with this?
