Google Cardboard is a virtual reality headset for the poor man. It doesn’t deliver a state-of-the-art VR experience like the popular Oculus, but it will give a taste of what’s possible with VR and what’s coming. It’s a foldable cardboard housing with two lenses that uses a smart phone for a screen. There are a range of apps, games and videos available for these devices which provide a rudimentary 3D and immersive experience. For example, you can ride dizzying virtual roller coasters and examine the virtual world as you move your head around. The technology has a long way to go but it’s fun to play around with for awhile, and it’s certainly a gift that will be traded and stolen in your white elephant exchange.
