How to do 6DoF VR with a smartphone?

• To create a VR smartphone application with 6 degree of freedom, you can enable 6Dof in a small area with Google Daydream: https://developers.google.com/vr/develop/unity/3dof-to-6dof

• However, if you want to use 6DoF within an virtually unlimited space, or with Google Cardboard, you can use this hacking technique: combine it with ARCore tracking. We describe how to do that in this tutorial. You can use this as a starting point as well with your own rendering: 1) apply your rendering to the ARCore Camera OR 2) re-use the ARCore camera transform (position and rotation) for your own custom camera.

Why?

This technique is incredibly convenient to do research on VR remolty. You just need a compatible smartphone and a smartphone VR headset for the stereoscopic view ( /!\ to work with this technique, you need to ensure the smartphone camera is not hidden).

Requirements

• In this tutorial, we consider you know how to generate an Android application Android SDK 7.0 (API Level 24) from a Unity project, and you have the set up to build such app . Otherwise, you can check the tutorial here: https://sites.google.com/ensc.fr/laurenthevin/scientific-mediation/accessible-treasure-hunting/tutorial-accessible-treasure-hunting from the section "Create the smartphone app"

• You use should Unity 2017.4.34f1 or later. In this tutorial, I use Unity 2019.2.10f1 (64-bit)
