I wonder how this would work without any magnetic switches - just that having made my own cardboard viewer for a nexus 7 and without the magnetic switch you have to tap the screen somehow which breaks the experience (for me)
Hi, Designer of the VR device posted here. The bottom of the viewer is open so you can touch the screen with your thumb. We really wanted to make the most sharable VR device so we focused on simplifying and making it fit into a pocket.
