This is a toolkit for Unity 3D which contains scripts for acquiring eye tracking data on the Microsoft HoloLens 2.

Documentation about the usage of the toolkit can be found in the projects wiki. Background information is provided in the associated publication.

An accompaning package for analysis of the acquired data using R can be found in the ARETT R Package repository.

A sample application integrating the toolkit into Unity project can be found in the ARETT Demo repository.

The toolkit is currently being developed for Unity 2019.4.20f1 and the Microsoft Mixed Reality Toolkit v2.5.4. However, it should work with all releases of the Unity 2019.4 LTS branch and future releases of Mixed Reality Toolkit. Compatibility with future versions of Unity is likely but not guranteed.
