About

Shared Space Experience is an MR co-location example for VIVE XR Elite. This example shows how to allow users to interact in the same physical and virtual space.

In this project, we demonstrate how to align the space between two VIVE XR Elites by Trackable Marker and Spatial Anchor.

   2. Follow Wave Unity SDK -- Unity Marker to setup Trackable Marker.
   3. Follow Wave Unity SDK -- Unity Scene Perception to setup Spatial Anchor.

3. Install following packages and assets:

   • Netcode for GameObjects
   • Netcode for GameObjects Community Extensions
   • Input System
   • TextMeshPro
   • KF Magic Effets Free

How to Play with VIVE XR Elites

1. Environment Setup
   1. Do Room Setup and make sure both VIVE XR Elites have the same floor height.
   2. Place the ArUco marker in a fixed place.
2. Install the App
   • Build the project and install the APK on VIVE XR Elites by Android Debug Bridge.
3. Play the Game
   1. Matching
      • In the launcher, you can choose to be a host or join others as a client. Maker sure all the VIVE XR Elites connect to the same local network.
   2. Aligning Space
      • The host can decide which align method to use.
        • Trackable Marker:
          1. The host have to scan the markers and select one for alignment.
          2. The clients scans the same marker to align the space.
        • Spatial Anchor:
          1. The host first create a spatial anchor with the right controller.
          2. The client then download the spatial anchor. The anchor will relocate and align the space automatically.
      • If the menu is not in a proper place, hold grip button of the left controller to adjust the menu position.
      • Once the alignment is completed, players can see each other's virtual controller models and check whether the space has been properly aligned.
   3. Playing
      • The host can start the game once all the players are aligned and ready.
      • The game is a simple PvP shooting game that the player wins by shooting down all the health bricks of other players.
        • Attack: Press the trigger on the right controller to shoot magic orbs. Press the grip button can change orb type.
        • Defense: Use the shield attached on the left controller to protect the health bricks.
