Welcome to the Tobii XR Developer Zone.
The Tobii XR SDK is designed to be device agnostic with support for eye tracking data from Unity, Unreal, Native and OpenXR when it becomes available. The SDK enables cross-platform development of eye tracking by providing simple methods to access eye tracking data as well as debugging tools to speed up development.
Tobii G2OM is a machine learning algorithm to accurately predict what the user is looking at, providing a consistent eye tracking experience between users and enabling developers to spend more time creating eye tracking applications and less time trying to figure out which object the user is looking at.
If you want to develop software for analytical purposes, post processing or aggregation of eye tracking data you need a special license from Tobii.
