 A user agent MAY dispatch this event type to indicate that something has occured which suggests the {{VRDisplay}} should be presented to. For example, if the {{VRDisplay}} is capable of detecting when the user has put it on, this event SHOULD fire when they do so with the reason "mounted".

 A user agent MAY dispatch this event type to indicate that something has occured which suggests the {{VRDisplay}} should exit presentation. For example, if the {{VRDisplay}} is capable of detecting when the user has taken it off, this event SHOULD fire when they do so with the reason "unmounted".

+<dfn event for="VRDisplay" id="vrdisplay-blur-event">blur</dfn>
 A user agent MAY dispatch this event type to indicate that presentation to the display by the page is paused by the user agent, OS, or VR hardware. While a {{VRDisplay}} is blurred it does not lose it's presenting status ({{isPresenting}} continues to report true) but {{getFrameData()}} returns false without updating the provided {{VRFrameData}} and {{getPose()}} returns null. This is to prevent tracking while the user interacts with potentially sensitive UI. For example: A user agent SHOULD blur the presenting application when the user is typing a URL into the browser with a virtual keyboard, otherwise the presenting page may be able to guess the URL the user is entering by tracking their head motions.

 A user agent MUST dispatch this event type to indicate that a {{VRDisplay}} has begun or ended VR presentation. This event should not fire on subsequent calls to {{requestPresent()}} after the {{VRDisplay}} has already begun VR presentation.
