Why don't you save up some money and invest in an actual VR headset? You can buy like a Windows Mixed Reality headset with controllers for $150 or less. It's way better than this cheap VR mess you're trying to do. I tried doing something like this before using a modified PS3 Move Camera along with using a streaming software to the phone on a google cardboard. The phone would lag and overheat. Using DiY Google Cardboard like headsets with streaming software and modified controllers using paid 3rd party drivers just doesn't give a smooth experience. The VR experience on that one was pretty bad but when I switched to the actual PC VR headsets the experience was very enjoyable.
