Unity XR Platform

A shared interaction model has to balance reuse with device differences. XR Interaction Toolkit gives creators a common vocabulary—interactors, interactables, hover, and select—across supported controllers and interaction modes. The design challenge is to make that vocabulary useful without concealing what a particular device can and cannot do.

XR Plug-in Management configures provider plug-ins, and Unity’s OpenXR package targets conformant runtimes. Shared concepts still meet specific limits. For mixed reality on visionOS, PolySpatial connects Unity authoring and simulation with RealityKit rendering; not every rendering technique carries across. Its Volume Camera makes spatial bounds an explicit authoring decision. Creators need to recognize these differences early enough to decide what to reuse and what to adapt.

A toolkit is only as approachable as its first working scene. XRI Starter Assets bring input actions, presets, and example prefabs together, including an XR Origin, teleportation, and interactable objects. Unity’s mixed reality template extends that starting experience with an in-scene menu for sample content and coaching controls.

That makes onboarding part of the product architecture. The useful handoff is a system people can learn from and change—not a disconnected list of settings. Defaults provide momentum; visible configuration preserves control as a project becomes more complex.

XR Device Simulator maps keyboard and mouse input to a simulated headset and controllers, so creators can exercise interactions in the Editor. For PolySpatial content on visionOS, Play to Device previews the scene on a simulator or device without rebuilding an Xcode project. These are complementary paths for keeping feedback close to authoring.

The platform principle is to use lightweight checks for frequent iteration and real hardware for spatial validation. Simulation makes behavior easier to inspect; a headset remains essential for judging scale, comfort, and the physical experience.
