360-degree VR (360-degree virtual reality) is an audiovisual simulation of an altered, augmented or substituted environment that surrounds the user, allowing them to look around them in all directions, just as they can in real life.
360-degree VR can be used for many purposes other than entertainment. The virtual reality technology can be used in most kinds of training that involve a physical environment, including pilot and driver training (as well as actual piloting or driving), surgery, and undersea and space exploration via remote-control robots.
There are a number of types of 360-degree VR, including live and previously captured video or real-time, real-time rendered 3D games, and pre-rendered computer graphics imagery (CGI).
What to Look For When Buying a 360-Degree Camera
360 cameras tend to fall into two camps: small, pocketable stick-style devices, and larger squarish (or circular) cameras. The former, such as the Samsung Gear 360, tend to be less expensive, and are designed for more casual and impromptu shooting. In the second category are cameras such as the Garmin Virb360 and Kodak Orbit360 4K, which are larger and more expensive, but tend to produce higher-quality video.
Be sure to think about how you plan to use a 360 camera before you purchase it; if you want to get some fun selfies with friends, then the stick-style cameras will fit your needs well. If you want to capture hair-raising exploits when you go skydiving or skiing, then a larger camera may be the better option.

One of the most compact 360-degree cameras, the Insta360 One connects to your iPhone's Lightning port (there's an Android adapter too), and uses the phone's screen as your viewfinder (the camera can also be used separately). Not only can it capture great 4K video and 24MP photos, but a slo-mo "bullet-time" feature lets you make Matrix-style movies, too. You can even livestream to Facebook and YouTube.

The second generation Gear 360 sports a new design that makes the camera smaller and easier to hold, but remains just as intuitive to use, and takes great pictures, too. The Gear 360 livestreams to Facebook and YouTube, too. Still, we have some reservations: Android users will have to own a Samsung smartphone to use the camera, and while it works with iPhones, not all of the Gear 360's features are supported. If you're looking for something more universal, the LG 360 cam supports all phones and costs $40 less, but has a lower-resolution camera.

The Virb 360 is Garmin's first 360 camera, but it gets almost everything right. The camera does a great job at stitching sharp and vivid 4K video, it's waterproof to 30 feet, and it can be controlled using voice commands. Plus, data from built-in sensors (GPS, barometer, compass, etc.) can be overlaid into your videos, so you'll know just how fast you were going when you wiped out.
It's about time GoPro made a 360 camera. The Fusion, which will be available in November, will shoot 3K video at 60 fps, 18MP still photos, and will capture spherical surround sound. Similar to other GoPro Hero cameras (as well as Garmin's 360 camera), you can control the Fusion with voice commands. It also has built-in image stabilization, GPS, Wi-Fi, and is waterproof to 16 feet.
