This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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() { ... };
Examples
window.onvrdisplayblur = function() { info.textContent = 'Display unfocused.'; };
