Extract eye tracker data from Vive Pro Eye


Recommended Posts

Hello, 

I've just started using the HTC Vive Pro Eye for a research project in Unity. 

I don't know how to extract data from the integrated Eye Tracker. I have already contacted the Tobii Pro Support but they could not help me.

I have also read the topics in this forum but I didn't find what I was looking for. 

Can someone help me? Thank you

Hi @Tesi,

we provide an Eye Tracking SDK for Vive Pro Eye that is called SRanipal SDK.  It is free for developers to integrate with their project and for the end-users to access via the SRAnipal runtime as the licensing is included as part of Vive Pro Eye hardware platform. Our SDK primarily offers things like feature data (gaze, pupil diameter/position...etc). You can see the full list of features in the image below.

Currently our Vive SRanipal SDK doesn’t allow access to the raw data from the Eye Trackers. Developers can only get access to a specific set of features but not the raw feed from the trackers.

Here is a webinar recording to help you understand more things about Vive Pro Eye and SRAnipal SDK: https://register.gotowebinar.com/recording/212634959163678731

Hi, it is weired that the devices did not provide the raw data of the eye-tracking. So what do I buy this device for? Just for some eyemovement video? Forgive my questions, because I am a rookie, I connected the unity sample eyemovement but can not find where the eyemovement data is stored.
