Not to be outdone, Google announced its Cardboard virtual reality headset at I/O 2014 and unveiled version 2 at the 2015 conference. Popping a smartphone into a cardboard container and then strapping it to your head may sound like a joke, but it actually works and it could become 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. Related is Durovis' Dive, which is essentially the same thing made of higher quality and more sweat-resistant materials.
With the popularity of Cardboard, Google decided it would release an even better one. Called Daydream, the device is pretty much a Gear VR but apparently there's a whole slew of Android phones getting revamped to provide a better VR experience with Daydream. Companies making the handsets will also likely release their own mobile headsets.
There's no official date for its release except an estimate for this fall. We'll update the list to see if the Google VR headset - or any others running the Daydream platform - makes the cut then.
