The read-only inputSources property of the XRSession interface returns an XRInputSourceArray object which lists all controllers and input devices which are expressly associated with the XR device and are currently available. These controllers may include handheld controllers, XR-equipped gloves, optically tracked hands, and gaze-based input methods. Keyboards, gamepads, and mice are not considered WebXR input sources.

Note: Traditional gamepad controllers are supported using the Gamepad API.


inputSources = xrSession.inputSources;


An XRInputSourceArray object listing all of the currently-connected input controllers which are linked specifically to the XR device currently in use. The returned object is live; as devices are connected to and removed from the user's system, the list's contents update to reflect the changes.

Usage notes

You can add a handler for the XRSession event inputsourceschange to be advised when the contents of the session's connected devices list changes. You can then either get the value of inputSources to examine the list, or you can refer to a reference to the list that you've previously saved.
