The source code can be found at https://github.com/XiangGuo1992/ORCL_VR_EyeTracking.

The Tobii Eye Tracking is integrated in HTC VIVE Eye Pro in Unity, Which is a part of projects from Omni-Reality and Cognition Lab in University of Virginia (https://engineering.virginia.edu/omni-reality-and-cognition-lab).

There are several Prerequisite for using these code:

1. [HTC VIVE Eye Pro](https://www.vive.com/us/product/vive-pro/) with Tobii Eye Tracking system

2. [Unity](https://unity.com/) version 2018.4.16 or 2018.3.14

3. [Python](https://www.python.org/) 3.6.3 ([Anaconda](https://www.anaconda.com/) version recommended)

4. [SteamVR](https://store.steampowered.com/steamvr)

5. Finish the [Set up for the HTC VIVE Eye Pro](https://enterprise.vive.com/eu/setup/vive-pro/)

6. [Tobii Pro SDK](http://developer.tobiipro.com/index.html) for your platform

The HTC VIVE Eye Pro hardware (headset, controller) is from HTC VIVE, the integrated eye tracker is from Tobii, they have provided multiple ways to get access to the eye tracking data:

- [Tobii Pro SDK](http://developer.tobiipro.com/index.html): A general SDK for getting eye tracking data. This repository will use Python and Unity only.

- [Tobii XR SDK](https://vr.tobii.com/sdk/develop/unity/): SDK for Unity, developed by Tobii too, to get started, follow the steps in this [link](https://vr.tobii.com/sdk/develop/unity/getting-started/vive-pro-eye/). Tobii XR requires a analytical license to get the raw data, otherwise, eye tracking can only be used for interactive use.

- [Vive Eye Tracking SDK](https://developer.vive.com/resources/knowledgebase/vive-sranipal-sdk/) : SDK for eye tracking from HTC. The forum for it can be found [here](https://forum.vive.com/forum/78-vive-eye-tracking-sdk/).

This repository includes sample code and tutorials for Python and Unity API of Tobii Pro SDK only.
