What was once a mere science fiction dream and a Hollywood movie plot device decades ago, virtual reality is now fast becoming a mainstream phenomenon.
With the unprecedented demand for the PlayStation VR, Oculus Rift and the HTC Vive computer rig, we'll likely see more receptive audiences joining in this trendy bandwagon of visual immersion.
But did you know that you don't have to spend hundreds or even thousands of dollars to get a decent virtual reality experience?
In fact, the main component that you need is likely one that you already own - yep, your smartphone!
In case you're wondering, your smartphone already has the necessary sensors for VR like gyroscopes and accelerometers and all you'll need is a viewer to stick your phone in.
You can get fancy gear like the Samsung Gear VR or Google's Daydream View but you don't have to. The $15 Google Cardboard will do just fine.
Cardboard is surprisingly simple. It's a low-cost, low-tech contraption you slide your phone into, and with a use of two 45 mm focal length lenses, turns it into a usable VR system!
Google even released Cardboard's schematics to the public so anyone can create their own DIY versions. Don't worry if you don't have the time. There are plenty of cheap Cardboard compatible options available online.
