句法

let inputSource = xrInputSourceEvent.inputSource;
					

XRInputSource object identifying the source of the user input event. This event indicates an action the user has taken using a WebXR input controller, such as a hand controller, motion sensing device, or other input apparatus.

范例

The snippet below shows a handler for the select event which looks specifically for events which happen on gaze input devices. The device type is identified by looking at the XRInputSource in inputSource 及其 targetRayMode 特性。

xrSession.onselect = event => {
  let source = event.inputSource;
  if (source.targetRayMode == "gaze") {
    /* handle selection using a gaze input */
  }
};
