This chapter will explore how to create more immersive experiences using the VIVE Tracker feature within the XR_HTCX_vive_tracker_interaction extension.

Setup the VIVE Ultimate Tracker

Connect VIVE Wireless Dongle to USB-C port. (Located on the battery cradle for XR Elite)
Once connected follow the steps to pair trackers. You can always pair and modify tracker settings from Settings > Input > Motion tracker.
Start VIVE Streaming on your PC.
Start your streaming session. For more information about VIVE Streaming visit this Page.
Once everything is set you will see the tracker in your SteamVR Monitor. Right click on the tracker and select Manage Trackers.
Select your desired Tracker Role. For this tutorial we chose Camera and Chest as we have two trackers connected.

Environment Settings

In the following, let’s see how to use this VIVE Tracker profile. You can check overall VIVE Tracker data defined in the Input Device HTC Vive Tracker (OpenXR) from menu item Window > Analysis > Input Debugger.

To use the VIVE Tracker, simply add the HTC VIVE Tracker Profile in Edit > Project Setting > XR Plug-In Management > OpenXR.

Binding the VIVE Tracker data path

Note : We have already created Action Maps for Vive Tracker.(Assets > Samples > VIVE OpenXR Plugin > {version} > VIVE OpenXR Samples > Samples > Commons > ActionMap.)

Add an action map to your existing Input Action. For this tutorial we will call it Ultimate Tracker.

Add Actions for each tracker. Here we are setting up the action map with actions for two trackers, but you can change it depending on how many trackers you are using. - Create two new actions and name them as you see fit UltimateTracker1_Position, UltimateTracker1_Rotation. - Bind the UltimateTracker1_Position action to devicePosition Camera XRViveTracker. - Bind the UltimateTracker1_Rotation action to deviceRotation Camera XRViveTracker.
Note: You will need to bind your tracker based on the tracker role that you set from SteamVR.
Repeat the above to add additional trackers.

Create a Cube in your scene and add a Tracker Pose Driver (Input System) component. Set the Position and Rotation Input from your Action Map. (You can create more cubes if you have more trackers)
Build your application or simply test from the editor by pressing on the play button. The cube should be moving based on the tracker position and rotation.
