The impact of watching a 360 movie using a headset (even if it’s a simple cardboard one) is something you can’t describe until you try it. It is fascinating how easy it is to trick our brains into believing what it sees.
I participated in serious research about VR and illusion a year after this project and designed a series of workshops with children all over Europe, where they explored VR through creating their own headsets and used cardboard as an anchor for navigating virtual worlds.
