You Don’t Need to Face the Camera to See the Screen
Almost every video you see, set-up guide, and demonstration from Sony has seen people directly facing the Camera for them to be able to see the PS4 Home Screen or at least be facing front and center in their world. While this will definitely provide the optimal experience, the picture will actually appear in the direction the PlayStation VR headset is facing when you turn it on. Therefore, if you’re facing away from the camera, yes, the display will be behind you.
Though this will remove a bit of the faff around setting up your PS4 for PSVR every time you want to turn it on, remember that if things do get all a little disoriented, you can always hold the Options button on your DualShock 4 to recenter the screen in the direction you’re facing. Things can and often do go a little off when you’re moving around in VR, so these are handy tips to remember.
