GOOGLE CARDBOARD - WHAT IS IT?
A BLUE BOX
You have a blue box in your hand, what is it? The Google Cardboard is a handy holder that lets you turn any smartphone into 3D virtual reality glasses. The main component is a cardboard box that is folded so that the smartphone can be used. The construction consists of two lenses through which you can watch videos or games on your smartphone.
WHAT CAN I DO WITH IT?
For example, download various apps for the Google Cardboard.
Or even easier. Watch 360° videos on Youtube and then switch to Google Cardboard mode (on the video below, a Google Cardboard icon appears next to the full screen option).
