Window.onvrdisplayblur

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.

The onvrdisplayblur property of the Window interface represents an event handler that will run when presentation to a display has been paused for some reason by the browser, OS, or VR hardware (when the vrdisplayblur event fires) — for example, while the user is interacting with a system menu or browser, to prevent tracking or loss of experience.

While a VRDisplay is blurred it does not lose it’s presenting status (VRDisplay.isPresenting continues to report true) but VRDisplay.getFrameData() returns false without updating the provided VRFrameData and VRDisplay.getPose() returns a VRPose with null members.

The event object is of type VRDisplayEvent.

Syntax

window.onvrdisplayblur = function() { ... };
