There remains a significant amount of confusion about the differences between Virtual Reality, Augmented Reality and Mixed Reality. (Check out our exhaustive primers on Augmented Reality and Mixed Reality for an in-depth look at the differences.) The public seems to think that AR is a phone experience, while only VR requires an HMD. Mixed Reality devices like the Microsoft Hololens use a headset to overlay 3D imagery on top of the real world. Very cool, but not Virtual Reality.
Virtual reality, or VR, is a technology that lets you figuratively step inside a computer-generated 3D world. You can explore and sometimes even manipulate objects in that world. Imagine virtually stepping inside a video game, where the game world feels as real as the non-game world. In fact, video games are one of the most exciting and engaging ways to enjoy VR today. https://www.youtube.com/watch?v=BpPcm3qze5I&t=1s
Special input devices are required for interaction with the virtual world. These include the 3D mouse, the wired glove, motion controllers, and optical tracking sensors. Controllers typically use optical tracking systems (primarily infrared cameras) for location and navigation, so that the user can move freely without wiring. Some input devices provide the user with force feedback to the hands or other parts of the body, so that the human being can orientate himself in the three-dimensional world through haptics and sensor technology as a further sensory sensation and carry out realistic simulations. Additional haptic feedback can be obtained from omnidirectional treadmills (with which walking in virtual space is controlled by real walking movements) and vibration gloves and suits.
Bees are, like, super important to how our ecologies work. You probably learned all of this in elementary school, but have you ever seen the process, from beginning to end? The National Honey Board wants to show you, in 360. You'll be a bee flying from flower to flower, then going back into the hive with the queen bee. After that, you'll take a look at how they get the honey out of the honeycombs and onto your table. Warning: Tons of buzzing. https://www.youtube.com/watch?v=4HnNKI0Vkds&t=1s
