These days, the use of AR devices and games like Pokemon Go, the words “virtual reality” and “augmented reality” get tossed around a lot. The revival of VR headsets revealed by the Oculus Rift has improvised the modern tech. They sound similar. They bleed into each other a bit as the technologies develop. Nonetheless, they are two very different terms. Characteristics of these readily differentiate them from each other.
What exactly Virtual Reality is?
VR goggles take over your vision entirely to give you the illusion that you’re in another environment. The HTC Vive, the Oculus Rift, and other goggles are fully opaque. You will experience when you wear them, covering your view. When you put them on when they turn off, you may assume that you are blind.
Nevertheless, when the headphones turn on, the lenses refract the LCD or OLED panels inside to fill your field of vision with whatever it projects. It can be a game, a 360-degree video or just the virtual space of the interfaces of the platforms. Visually, you’re brought wherever the headset wants you to go. Simulated environment replaces the outside world.
Degrees of Freedom
Most tethered VR headsets, such as the Rift, Vive, PlayStation VR, and Windows Mixed Reality headsets, use six-degree (6DOF) motion tracking with external sensors or cameras (for Rift, Vive, and PS VR) or external (for WMR) cameras. This means the headsets not only sense the direction you ‘re looking. But any movement you ‘re making in certain directions. It helps you to walk around in a virtual environment. Virtual hands, coupled with 6DOF motion controls does this.
Usually, this room limits to a few square meters across. However, it is much more immersive than just standing still and looking in various directions. The downside is that you must be careful not to go through any cable connecting the headset to your device or gaming console.
Virtual reality substitutes your world for both games and apps. It takes you to other locations. It doesn’t matter where you are, physically. In games, you could be sitting in a starfighter ‘s cockpit. You could digitally tour distant locations in apps, as though you were there. In virtual reality, there are lots of possibilities. They all include replacing everything around you with something special.
What exactly Augmented Reality is?
While virtual reality replaces your vision, augmented reality adds. AR gadgets such as the Microsoft HoloLens and numerous “smart glasses” at the enterprise level are translucent. It lets you see everything in front of you as if you were wearing a small pair of sunglasses. The technology is built for free movement. It projects photos onto everything you look. The technology applies to smartphones with AR applications and games such as Pokemon Go. These uses your phone’s camera on the device to monitor the surroundings. It overlays additional details on top of that.
AR displays may deliver anything as basic as a time-showing data overlay to something as complex as holograms floating in a room’s centre. Pokemon Go projects a Pokemon on your phone. In addition to what the camera is looking at. Meanwhile, the HoloLens and other smart glasses such as the mysterious Magic Leap One allow you to digitally place floating device windows and 3D decorations around you.
Compared with virtual reality this technology has a distinct disadvantage: visual immersion. Although VR fully covers your field of vision and removes it, AR apps only appear on your smartphone or tablet screen. And even the HoloLens can only project images in a small area before your eyes. If a hologram disappears as it passes out of a circle in the centre of your vision, or when you have to look at a tiny screen while thinking that the object on that screen is really in front of you, it’s not quite immersive.
Degrees of Freedom
With 3DOF, basic AR that overlays clear details about what you are looking at will work just fine. Nonetheless, in some way, most AR applications need 6DOF, monitoring the physical location. So that the program can maintain accurate locations in 3D space for the images it projects. That’s why the HoloLens uses a stereoscopic camera. It also uses sophisticated pattern recognition to decide where it is at all times. And why more powerful, AR-centered iPhones like the iPhone X use multiple rear-facing cameras to monitor distance.
Distinguished between AR and VR
Virtual reality and augmented reality do two very different tasks in two entirely different ways, with the systems themselves having identical designs. VR replaces fact and takes you elsewhere. AR adds information to the fact, adding knowledge on top of what you already see. These are strong innovations that still need to make their mark with customers. But they do show a lot of promise. We will change the way we use computers in the future entirely. But whether either or both can succeed is the guess of everybody right now.
