When I am viewing a website in VR, I want to be able to access my browser controls in place, so that I can perform browsing operations without losing losing my sense of place.

Resets HMD sensor when pressed

caseyyee commented 9 years ago

Probably want to map this to a keypress or a button rather than HUD. The direction you are resetting to is probably not going to be where the HUD interface will be.

jcarpenter commented 9 years ago

We need it in the HUD also, because we can't rely on the keyboard button not being over-ridden by developers, or on the user having a keyboard at all. All critical functions must work with GearVR-calibre input model.

jcarpenter commented 9 years ago

Per discussion during work week, will check how GearVR implements this in a look-based cursor-model context.

jcarpenter commented 9 years ago

The GearVR solution is to set the sensor to whatever the user's forward vector was when they invoked the system menu. For example:

I'm playing a game on the couch.
I turn my head 90° to my right, and long press the Gear's hardware back button to open the system menu. The menu opens centered to my current physical forward vector.
I select "Reset sensor" command. The system sensor forward vector now matches my physical forward vector. Through the transparent menu I can see that my orientation in the active game has also updated.

From @caseyyee in https://github.com/MozVR/horizon/issues/86#issuecomment-121322335:

We have center viewport currently mapped to the back button on the Xbox controller (left of the vendor button). This is actually a pretty convenient place for it, but we could still use some UI to go with it.
