Gear VR start of as 2D View then go to VR mode

Hello,

I'm wondering if this action is possible,

so what I want is to make an app, and when you open it you need to log in and preferably in 2D mode, which means you can tap on your phone and use the keyboard. Then after that when you press log in, it will show up dialog to put up the gear vr device and then after it is plugged in, it will goes to the VR mode.

It doesnt matter if it can be achieved through Unity 5.1 or Unity Integrated Plugin, I have been searching for long time and couldnt find anything. Any help would be appreciated

Thanks
