ABSTRACT
By now, you probably already know that Unity is a great engine backed up by an awesome team. If you need any evidence, just take a look at all of the documentation and free code they give you to get started on your projects. It really is impressive how much they give; free assets, free code, and online tutorials. One tutorial session offered by Unity is the VR Samples series (https://unity3d.com/learn/tutorials/topics/virtual-reality) which is all about building VR user interfaces. It not only includes a video tutorial but you get also all of the code and assets to use in your own projects. Most importantly, it includes a great framework for interaction that we can use to save a ton of time by having the basics in place.
