HMDVRDevice

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HMDVRDevice interface of the WebVR API represents a head mounted display, providing access to information about each eye, and allowing us to modify the current field of view.

Methods

HMDVRDevice.getEyeParameters()

Returns current parameters for the eye specified as its argument ("left" or "right") — such as field of view information — stored in a VREyeParameters object.

HMDVRDevice.setFieldOfView()

Sets the field of view for both eyes.

Properties

This interface doesn't define any properties of its own, but it does inherit the properties of its parent interface, VRDisplay.

VRDisplay.hardwareUnitId Read only

Returns the distinct hardware ID for the overall hardware unit that this VRDevice is a part of. All devices that are part of the same physical piece of hardware will have the same hardwareUnitId.

VRDisplay.displayId Read only

Returns the ID for this specific VRDevice. The ID shouldn’t change across browser restarts, allowing configuration data to be saved based on it.

VRDisplay.displayName Read only

A human-readable name to identify the VRDevice.

Examples

The following example, taken from the WebVR spec, finds the first available HMDVRDevice and its associated PositionSensorVRDevice, if it has one.

navigator.getVRDevices().then(function(devices) {
  for (var i = 0; i < devices.length; ++i) {
    if (devices[i] instanceof HMDVRDevice) {
      gHMD = devices[i];
      break;
    }
  }

  if (gHMD) {
    for (var i = 0; i < devices.length; ++i) {
      if (devices[i] instanceof PositionSensorVRDevice && devices[i].hardwareUnitId === gHMD.hardwareUnitId) {
        gPositionSensor = devices[i];
        break;
      }
    }
  }
});

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.
