The XRInputSourceEventInit dictionary's inputSource property is used when calling the XRInputSourceEvent() constructor to specify the XRInputSource from which the newly-created event is being sent.

Of course, as a general rule, you won't need to create XRInputSourceEventInit objects yourself. These events are generated by and sent to you by the WebXR infrastructure.


let xrInputSourceEventInit.inputSource = xrInputSource;

let xrInputSourceEventInit = { inputSource: xrInputSource };

let xrInputSourceEvent = new XRInputSourceEvent(type, { inputSource: xrInputSource });


An XRInputSource object indicating the source of the newly-created XRInputSourceEvent to be created. The new object's inputSource will be set to this value.


This example creates a new select event and sends it to the XRSession.

let event = new XRInputSourceEvent("select", {
  frame: eventFrame,
  inputSource: source
if (event) {
