PositionSensorVRDevice.resetSensor

The resetSensor() method of the VRDevice interface can be used to reset the sensor if desired, returning the position and orientation values to zero.

Syntax

PositionSensorVRDevice.resetSensor();

Parameters

None.

Returns

Void.

Examples

Our positionsensorvrdevice demo uses the WebVR API to update the view of a simple 2D canvas scene on each frame of a requestAnimationFrame loop. It features, among other things, a "Reset Sensor" button in the UI, which when pressed runs the resetSensor() function on the position sensor. The JavaScript looks like this:

document.querySelector('button').onclick = function() {
  gPositionSensor.resetSensor();
}

When the button is pressed, the current position, orientation, etc. of the sensor/head mounted display is set to be 0 — this makes the method useful for calibration when an app is first loaded.

Browser compatibility

• [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.
