I have tried Dive 7 with Tango tablets and while it is the best option for now it has some flaws. I cannot get mine to focus and the lenses fall out. The tango also has some latency issues currently (80+ ms).
Mobile VR with positional tracking is extremely awesome though! Thanks for the info faduci.
If anyone has a tango and Dive 7 check out my Tango VR Hackathon App: https://play.google.com/store/apps/details?id=com.CorvusVR.TangoWithAutism
