Google Cardboard was first unveiled in 2014, as quite literally a folding cardboard container into which a smartphone could be placed. The beauty of Google Cardboard is two-fold: firstly, the hardware cost is almost minimal, often free, and secondly, it’s universal, supporting a wide range of smartphone models – essentially, anything that will fit into the front and stay secure.
Google Cardboard is something of a breakaway success, allowing people to sample VR content (be that from Google or elsewhere), without having to invest in a more substantial system: Google reports that five million Cardboard viewers have shipped. Google has a range of applications for the device, and has highlighted VR for development and investment in the future. Importantly, Cardboard is not only this cardboard viewer, but also the name of the VR platform from Google.
Cardboard is really an ad hoc VR viewer: there’s no head strap and if there was it would be uncomfortable to wear, instead intended to be held to the face to view the content. There are a range of Cardboard apps for content, as well as being able to view 360 environments such as Google Street View or watching 360 content on YouTube.
Cardboard makes perfect sense: if you want to dip your toe into VR, this is a good place to start.
