VRDevice.deviceId

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The deviceId read-only property of the VRDevice interface returns the ID for this specific VRDevice. The ID shouldn’t change across browser restarts, allowing configuration data to be saved based on it.

Syntax

var deviceID = VRDevice.deviceId;

Value

A DOMString containing the ID of the specific VR device.

Examples

The following snippet (see our VRDevice example) returns an array of all the VRDevices connected to your computer via Navigator.getVRDevices(). For each connected device it then prints out the VRDevice.hardwareUnitId, deviceId, and VRDevice.deviceName.

var list = document.querySelector('ul');
var info = document.querySelector('p');
if(navigator.getVRDevices) {
  navigator.getVRDevices().then(function(myDevices) {
    reportDevices(myDevices);     
  });
} else {
  info.textContent = 'WebVR API not supported by this browser.'
}

function reportDevices(devices) {
  for(i = 0; i < devices.length; i++) {
    var listItem = document.createElement('li');
    listItem.innerHTML = 'Device ' + (i+1)
                 + ': <strong>Hardware ID</strong>: ' + devices[i].hardwareUnitId
                 + ', <strong>VD Device ID</strong>: ' + devices[i].deviceId
                 + ', <strong>VR Device Name</strong>: ' + devices[i].deviceName
                 + '.';
    list.appendChild(listItem);
  }
}

[1] The support in Chrome is currently experimental. To find information on Chrome's WebVR implementation status including supporting builds, check out Bringing VR to Chrome by Brandon Jones.
[2] The support for this feature is currently disabled by default in Firefox. To enable WebVR support in Firefox Nightly/Developer Edition, you can go to about:config and enable the dom.vr* prefs. A better option however is to install the WebVR Enabler Add-on, which does this for you and sets up other necessary parts of the environment.
[3] The dom.vr* prefs are enabled by default at this point, in Nightly/Aurora editions.
