Platform gestures

Some XR platforms can detect hand and finger gestures using their native hardware and software capabilities. Where available, such gesture data is made available to a Unity app through a provider plugin or the platform's own, separate SDK.

The XR platforms with native gesture detection include:

Platform Provider plugin Supported platform gestures
[OpenXR] [OpenXR], [XR Hands] Pinch, aim, system gesture, system menu gesture through the Meta AIM hand OpenXR extension. Grip, aim, pinch, and poke through the Hand Interaction Poses OpenXR extension.
[Hololens 2] [Mixed Reality OpenXR plugin]
[Magic Leap 2] Magic Leap XR plugin]

Platform gestures might require their own set of components or platform-specific extensions. As such they often aren't suitable for cross-platform projects.
