[the sdk to record the trace of the head and the eye, for the HTC VIVE Pro Eye device.]

Sorry, I have a question here that I would like to ask everyone. I am conducting a study  on the recording patterns of eye and head movement trajectories while watching 360 degree videos.
I have purchased a new HTC VIVE Pro Eye device. Is there any open source SDK that can record head and eye movements and export them in latitude and longitude format
If so, can you provide me with a link?
If not, should I purchase other devices?

hi, I have the same research goal as you. But first of all, I have a question. Is there any open source SDK that allows me to obtain the trajectory of head movement and eye gaze? My device is HTC VIVE Pro Eye.
