While virtual reality has captured the hearts, minds, and wallets of gamers, futurists, and Facebook executives everywhere, Google has mostly kept off the field -- until today.
At its annual I/O developers conference, the search giant handed out a mysterious package as part of its now-expected goodie bag for attendees. Alongside the choice between a brand new LG G Watch or Samsung Gear Live smartwatch, giddy developers got their hands on a virtual reality headset that just happened to be made from cardboard.
Intended to be a do-it-yourself starter kit, Google Cardboard is a head-mounted housing unit for your smartphone that lets you blend everyday items into a VR headset. With a $10 lens kit, $7 worth of magnets, two Velcro straps, a rubber band, and an optional near-field communication sticker tag, you can have your very own scrappy headset.
Considering Oculus VR, now owned by Facebook, uses smartphone screens for its Rift device, it's not too farfetched to expect a reasonably usable version of the technology can be achieved this way.
While it sounds goofy and inherently tongue-in-cheek, the Cardboard project was concocted by Google's David Coz and Damien Henry at the Google Cultural Institute in Paris as part of the company's "20 percent time" initiative with the aim of inspiring a more low-cost model for VR development. After an early prototype wowed Googlers, a larger group was tasked with building out the idea.
"Virtual reality has made exciting progress over the past several years. However, developing for VR still requires expensive, specialized hardware. Thinking about how to make VR accessible to more people, a group of VR enthusiasts at Google experimented with using a smartphone to drive VR experiences," reads Google's new developers page for Cardboard.
Google isn't stopping at hardware, if you'll allow us to call it that. The company released today a self-described experimental software development kit for Cardboard experiences. Cardboard also has an Android companion app that's required to utilize Google's own VR-specific applications, called Chrome Experiments. Some use cases Google cites now are flyover tours in Google Earth, full-screen YouTube video viewing, and first-person art exhibit tours.
"By making it easy and inexpensive to experiment with VR, we hope to encourage developers to build the next generation of immersive digital experiences and make them available to everyone," Google says.
