Virtual reality isn't some far-fetched science fiction concept anymore. It's a real thing thanks to (what else?) our smartphones. But VR may not work quite how you expect.
Normally, when you're watching video on your phone, it doesn't matter where you put it — the video stays the same. With VR, the position of your phone determines what you see on screen. Using sensors, such as a gyroscope (which measures rotational movements), a VR device allows you to "look" around the virtual landscape surrounding you, in 360 degrees, as you turn your head.
But what you see in VR is only half of the experience. Depending on what you're looking at, it can be cool on its own; but usually, you need surround-sound audio cues to make the experience feel real. With a pair of headphones on, you can get immersive audio that instructs you where to look in your virtual world — just like sounds do in real life. Using headphones paired with Dolby Atmos for VR, for example, a loud thunk "behind" may tell you to turn around; or if a person speaking is speaking to your left, you'll turn to look towards them.
Those are the basics behind virtual reality. If you have any other questions, head to the comments and we'll hop in to answer.
