World space 2D UI interactions with VR

Station descriptor

2D UI components can be selected and manipulated using the ray and trigger button on your controller.

The components shown here have 2 states: default and selected.

Overview

XRI provides the means of interacting with Unity's UGUI system, and this station demonstrates its use. UI interaction has the following requirements:

  • An XR UI Input Module - there is one located in the Complete Set Up Prefab, attached to the EventSystem GameObject.
  • The Render Mode of the Canvas must be set to World Space.
  • The top-level UI Canvas must also include a Tracked Device Graphic Raycaster component.

The input used to activate UI is the UI Press Action, located in the XRI Default Input Actions on each hand.
