The tech everyone wanted to try out at the Jisc Digital Festival this year (digifest15) didn’t cost hundreds of pounds – instead it was an ultra low cost virtual reality headset based on the Google Cardboard design, which you simply slot your Android phone into. Google Cardboard is the successful virtual reality product you might not have heard of – over 500,000 units of Google Cardboard have now been shipped since its launch last year, and there are over 250 Cardboard compatible apps in the Google Play Store.
Google Cardboard came out of a “20% project” by David Coz and Damien Henry at the Google Cultural Institute in Paris, and launched last summer at Google’s IO developer conference. IO attendees are accustomed to receiving gifts of the latest Google hardware like smartphones, tablets or laptops, so you can imagine that being given a piece of cardboard might initially have been something of a disappointment. Here’s how it unfolded, courtesy of TechCrunch’s Greg Kumparak…
Fast forward to early 2015 and Google has quietly turned virtual reality into a paying business by giving away the Cardboard design specs, so anyone can make compatible virtual reality viewers. It also makes software development kits (SDK) freely available for Android and the popular Unity 3D environment. In turn Google makes money from the sale of Cardboard compatible apps through its commission on Play Store sales.
What’s really telling about Cardboard is that it shows you actually already had virtually all the hardware you needed for virtual reality – in your pocket. Perhaps the message here is that the smartphone has already usurped the nascent virtual reality viewer product category, as it absorbed much of the market for digital cameras, music players, maps, books etc. And as the screenshot at the top of the post alludes to, perhaps we are finally approaching the world envisaged by William Gibson in his seminal cyberpunk novels.
Educators and e-learning specialists attending digifest15 told me that they were very excited by Google Cardboard, due to its immediate availability and low cost. What can you see yourself using it for?
That’s all well and good, and I have plenty of boxes around I can chop up … but where in the sam hill am I supposed to get hold of a compatible lens? I certainly don’t have the manufacturing facilities to shape glass or transparent PVC to the required shape with better than 0.1mm accuracy and ROHS complicance…
Mark, since Google open sourced the Cardboard design you can already buy a huge variety of kits, ready-made units and parts to build your own. There are some pointers at https://www.google.com/get/cardboard/get-cardboard.html. For the dedicated maker, I see compatible lenses available for £0.61 on eBay – search for “google cardboard lenses”. Happy hacking!
