Creating Gaze-able UIs

1. In the Hierarchy panel, add a Canvas by right-clicking and selecting UI > Canvas. The canvas appears in the Hierarchy.
2. In the Hierarchy, select the Canvas. In the Inspector, under Rect Transform, set the following settings to position the Canvas within reach and scale it to a manageable size:
   • Canvas > Render Mode: World Space
   • Rect Transform > PosX: 0
   • Rect Transform > PosY: 1.15
   • Rect Transform > PosZ: 1.5
   • Rect Transform > Width: 480
   • Rect Transform > Height: 720
   • Rect Transform > Scale: [0.0005, 0.0005, 0.0005]
3. Add a panel to the Canvas by right-clicking on the Canvas in the Hierarchy and selecting UI > Panel. The panel appears in the Hierarchy.
4. Add some UI elements to the panel to interact with. For example, right-click on the Panel in the Hierarchy and select UI > Button - TextMeshPro. The button element appears on the Panel. Add as many elements as you desire to create your UI.
   

1. Right-click on the Canvas, and select Interaction SDK > Add Gaze Interaction to Canvas. The wizard for that menu item appears.
   
2. In the wizard, you may see a message about a missing PointableCanvasModule. Select Fix. This adds the module to the scene’s EventSystem object, or creates an object that carries both. PointableCanvasModule is a scene-level singleton, so it does not go on the Canvas.
   
3. If you want to further customize the interaction, adjust the interaction’s settings in the wizard. For details on the available options, see the Gaze Canvas Quick Action documentation.
4. Select Create. The wizard automatically adds the required components for the interaction to the Canvas. It also adds components to the camera rig if those components weren’t already there.
   

1. Open the Link desktop application on your computer.
2. Put on your headset, and, when prompted, enable Link.

1. Make sure your headset is connected to your development machine.
2. In Unity Editor, select File > Build Profiles.
3. Click Open Scene List to open the Scene List window.
4. Add your scene to the Scene List by dragging it from the Project panel or by clicking Add Open Scenes.
5. Click Build and Run to generate an .apk and run it on your headset. In the File Explorer that opens, select a location to save the .apk to and give it a name. The build process may take a few minutes.
6. In your headset, you can interact with the UI at a distance using gaze and hands.
