Spatial Demo

Summary

A stick controller displayed on a smartphone can be used to control a character in real space.Spaces are spatially recognized by AR Foundation.It uses the Dynamic OpenXR Loader, which works as a smartphone app when launched, and enables OpenXR after connecting the AR glasses to enable the AR experience.

• Functions realized on a smartphone by Dual Render Fusion
  • Mesh display of the space analyzed by the device in the same spatial coordinates as AR glasses
  • Virtual controller for character manipulation
  • Display of the image being viewed on the AR glasses side
  • Various debugging information
• Supported Interactions
  • Hand Tracking(of MRTK3 feature)
  • Touch Screen interface
• Snapdragon Spaces features used primarily
