I spent much of yesterday afternoon and evening trying out the new Gear VR environment. A few more tweaks would really help the usability of it.
1) The Samsung Gear controller has a trigger button on it. In most other apps where the trigger doesn't have a different function from tapping the trackpad, it duplicates a click to select the on-screen item you're pointing at. I find the trigger to be much more useful to select stuff. It's easy to accidentally scroll/swipe the trackpad while trying to push down on it as a button. Supporting the trigger would reduce inadvertent clicks on the wrong item.
2) There should be a phone battery meter that we could turn on in the settings. It would be really disappointing to get to the climax of a movie or TV show just to realize you didn't have enough juice to finish what you were watching. If I saw that my battery was down to, say 20% or something ahead of time, I'd either plug it in or pick something shorter to watch.
3) Add some kind of clock. The headset can get pretty immersive and I didn't realize I'd been wearing it for nearly 4 hours until my wife tapped me on the shoulder and asked what I wanted to do for dinner.
If you really wanted to stick to the physical realm scheme, the apartment could have a virtual cell phone lying on the coffee table displaying the time & battery level. Heck, it could also show WiFi connection and cell signal strength. The virtual drive-in could have this info located on a dashboard display.
