In 2014, at their I/O developers conference, Google showed the world what amazing things you could do with a little bit of extra equipment and your smartphone.
David Coz and Damien Henry, Google engineers at the Google Cultural Institute in Paris, created Google Cardboard in their 20% “Innovation Time Off”.
Google Cardboard is a virtual reality (VR) platform on a smartphone to be used with an headset. Named after the actual cardboard viewer, the platform is intended as a low-cost system to encourage interest and development in VR applications.
The viewer is used by placing a smartphone into the back of it and viewing through the lenses in the front.
