Hi @simonaboj, thanks for your query. Please bear aware that the Tobii Pro SDK Unity Bindings is within the domain of the Tobii Pro business department.
This forum is intended for support with the Tobii Tech Consumer level eye trackers (4C, Eyex, etc) and their associated SDK’s.
Please get in touch with Tobii Pro Support team directly @ http://www.tobiipro.com/contact/contact-support/ for an
answer to your query.
That being said, if your intention is to create GazeAware objects, it may be a better fit for your needs to look at the Tobii XR SDK https://vr.tobii.com/sdk/develop/unity/ which has Unity Bindings and supports the HTC VIVE Pro Eye & Tobii HTC VIVE.
You can download it @ https://vr.tobii.com/sdk/develop/unity/
We also include a few samples to illustrate how to setup gaze enabled objects.
Please check it and let us know if you have any further questions, but assuming you wish to stay with the Pro SDK channel, then please get in touch with the support team over there. Thanks for your understanding.
