This feature is obsolete.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








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() {

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.

  • [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.
