Web/API/HMDVRDevice

ObsoleteThis feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

This is an experimental technologyCheck 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, VRDevice.

VRDevice.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.
VRDevice.deviceId 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.
VRDevice.deviceName 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;
      }
    }
  }
});
