Google announced its Cardboard virtual reality headset way back at I/O 2014. Popping a smartphone into a cardboard container and then strapping it to your head may sound like a joke, but it actually works and is a low-cost way to experience virtual reality.
After all, your smartphone contains all the necessary gyroscopic sensors and positioning systems to accurately track your head movements. There’s actually a bunch of unofficial Cardboard headsets but Google also now sells the real deal in its store. It’s better than you’d think… honest.
