 A viewer for 360 photos or videos should not respond to head translation, since the source material is intended to be viewed from a single point. While some headsets naturally function this way (Daydream, Gear VR, Cardboard) it can be useful for app developers to specify that they don't want any positional tracking in the matrices they receive. (This may also provide power savings on some devices, since it may allow some sensors to be turned off.) That can be accomplished by requesting a "headModel" `VRFrameOfReference`.

 ### Room-scale tracking and boundaries
 
-Some VR devices have been configured with details about the area they are being used in, including things like where the floor is and what boundaries of the safe space is so that it can be communicated to the user in VR. It can be beneficial to render the virtual scene so that it lines up with the users physical space for added immersion, especially ensuring that the virtual floor and the physical floor align. This is frequently called "room scale" or "standing" VR. It helps the user feel grounded in the virtual space. WebVR refers to this type of bounded, floor relative play space as a "stage". Applications can take advantage of that space by creating a stage `VRFrameOfReference`. This will report values relative to the floor, ideally at the center of the room. (In other words the users physical floor is at Y = 0.) Not all `VRDevices` will support this mode, however. `createFrameOfReference` will reject the promise in that case.
