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.

方法

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 对象。
HMDVRDevice.setFieldOfView()
Sets the field of view for both eyes.

特性

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

VRDevice.hardwareUnitId 只读
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 只读
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 只读
A human-readable name to identify the VRDevice .

范例

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;
      }
    }
  }
});
