 # Eye tracking examples in MRTK
 This page covers how to get quickly started with using eye tracking in MRTK by building on our provided [MRTK eye tracking example package](https://github.com/Microsoft/MixedRealityToolkit-Unity/tree/mrtk_release/Assets/MixedRealityToolkit.Examples/Demos/EyeTracking).
 The samples let you experience one of our new magical input capabilities: **Eye tracking**! 
-The demo includes a number of different use cases ranging from implicit eye-based activations to how to seamlessly combine information about what you are looking at with **voice** and **hand** input.

 This enables users to quickly and effortlessly select and move holographic content across their view simply by looking at a target and saying _'Select'_ or performing a hand gesture. 
 The demos also include an example for eye-gaze-directed scroll, pan and zoom of text and images on a slate. 
 Finally, an example is provided for recording and visualizing the user's visual attention on a 2D slate.

 These are some of the examples showcased in this tutorial about eye-supported navigation.
 In addition, there is an example for hands-free rotation of 3D holograms by making them automatically rotate based on your current focus.
