What is Virtual Reality ?

Virtual Reality (VR) is that the use of technology to make a simulated environment. Unlike traditional user interfaces, VR places the user inside an experience. rather than viewing a screen ahead of them, users are immersed and ready to interact with 3D worlds. By simulating as many senses as possible, like vision, hearing, touch, even smell, the pc is transformed into a gatekeeper to the present artificial world. the sole limits to near-real VR experiences are the supply of content and cheap computing power.

What’s the difference Between Virtual Reality and Augmented Reality?

Virtual Reality and Augmented Reality are two sides of an equivalent coin. you'll consider Augmented Reality as VR with one foot within the real world: Augmented Reality simulates artificial objects within the real environment; virtual reality creates a man-made environment to inhabit.

In Augmented Reality, the pc uses sensors and algorithms to work out the position and orientation of a camera. AR technology then renders the 3D graphics as they might appear from the point of view of the camera, superimposing the computer-generated images over a user’s view of the important world.

In virtual reality, the pc uses similar sensors and math. However, instead of locating a true camera within a physical environment, the position of the user’s eyes are located within the simulated environment. If the user’s head turns, the graphics react accordingly. instead of compositing virtual objects and a true scene, VR technology creates a convincing, interactive world for the user.

Virtual Reality technology

Virtual Reality’s most immediately-recognizable component is that the head-mounted display (HMD). citizenry are visual creatures, and display technology is usually the only biggest difference between immersive virtual reality systems and traditional user interfaces. as an example , CAVE automatic virtual environments actively display virtual content onto room-sized screens. While they're fun for people in universities and large labs, consumer and industrial wearables are the Wild West .

With a multiplicity of emerging hardware and software options, the longer term of wearables is unfolding but yet unknown. Concepts like the HTC Vive Pro Eye, Oculus Quest and Playstation VR are leading the way, but there also are players like Google, Apple, Samsung, Lenovo et al. who may surprise the industry with new levels of immersion and usefulness . Whomever comes out ahead, the simplicity of shopping for a helmet-sized device which will add a living-room, office, or factory floor has made HMDs center stage when it involves virtual reality technologies.

Virtual Reality and the importance of audio

Convincing virtual reality applications require quite just graphics. Both hearing and vision are central to a person’s sense of space. In fact, citizenry react more quickly to audio cues than to visual cues. so as to make truly immersive virtual reality experiences, accurate environmental sounds and spatial characteristics are a requirement . These lend a strong sense of presence to a virtual world. To experience the binaural audio details that enter a virtual reality experience, placed on some headphones and tinker with this audio infographic published by The Verge.

While audio-visual information is most easily replicated in virtual reality, active research and development efforts are still being conducted into the opposite senses. Tactile inputs like omnidirectional treadmills allow users to feel as if they’re actually walking through a simulation, instead of sitting during a chair or on a couch. Haptic technologies, also referred to as kinesthetic or touch feedback tech, have progressed from simple spinning-weight “rumble” motors to futuristic ultrasound technology. it's now possible to listen to and feel true-to-life sensations along side visual VR experiences.

Major players in Virtual Reality: Oculus, HTC, Sony

As of the top of 2018, the three best selling virtual reality headsets were Sony’s PlayStation VR (PSVR), Facebook’s Oculus Rift and therefore the HTC Vive. This wasn't a surprise, seeing because the same three HMDs had also been best sellers in 2017. 2019 sees the VR landscape broadening with Google, HP, Lenovo, et al. looking to grab a bit of the still-burgeoning market.

Here’s a look at 2019’s major VR hardware manufacturers and the devices they are manufacturing:

Oculus Rift, Oculus Rift S, Oculus Go, Oculus Quest

Oculus Rift, Oculus Rift S, Oculus Go, Oculus Quest Originally funded as a Kickstarter project in 2012, and engineered with the assistance of John Carmack (founder of Id Software, of Doom and Quake fame), Oculus became the first leader in computer game hardware for video games. Facebook bought Oculus in 2014, and brought the company’s high-end VR HMD to plug for consumers. More recently, Oculus has seen success with the lower-price, lower-powered Oculus Go, and 2019 will see the discharge of multiple new iterations on the hardware, including the tethered Rift S and therefore the stand-alone Oculus Quest.

The headset launches first half of 2019 and will list for $399.

HTC Vive, HTC Vive Pro Eye, HTC Cosmos, HTC Focus, HTC Plus

The HTC Vive has been one among the best VR HMDs on the market since its consumer release back in 2016. Manufactured by HTC, the Vive was the primary VR HMD to support SteamVR. The Vive has been locked in fierce competition with the Oculus Rift since release, as both headsets aimed toward an equivalent top end of the VR enthusiast market. The Vive has proven itself a durable workhorse for enterprise solutions, while also delivering one among the simplest consumer VR experiences available. The Vive was first released back in 2016, and has skilled several iterations, with the addition of a wireless module. The Vive Pro came call at 2018 and therefore the refore the Vive Pro Eye and the HTC Vive Cosmos are both slated for release within the last half of 2019.

Specification of HTC Vive Cosmos



Details remain scarce on the Cosmos, which seems like it's going to plan to bridge the standard gap between tethered and untethered headsets. The Cosmos would require tethering to a different device, but it's going to not be limited to high-end gaming PCs. A VR headset which will tether to a smartphone? Interesting idea. The Vive Cosmos promises “crystal-clear graphics” because of a replacement pixel-packing process that aims to attenuate screen effect the maximum amount as possible. The HMD’s tracking system promises wide and accurate tracking, gesture controls, and a 6 Degrees of freedom (DOF) headset-and-controller setup. No word on price or release date for the Cosmos yet, but expect it sometime within the last half of 2019.

Sony’s PSVR

Sony’s PSVR Sony’s entry into the market is that the lowest powered of the three best-selling VR HMDs, but the PSVR features a big advantage over the Rift and Vive. Because it’s tethered to the Playstation 4 gaming system, there was a huge , pre-existing user base of 10s of a lot of gamers, many of whom were wanting to try their hand at VR. Because that user base already had a PS4, Sony’s customers didn’t need to purchase/upgrade their hardware , making the PSVR the foremost “affordable” of the high-end HMDs. As such, the PSVR is that the best-selling virtual reality HMD on the market, moving over 4 million units since its initial release, and showing that, if nothing else, VR gaming is here to remain .

How Virtual Reality is being used today

How virtual reality is getting used today Unsurprisingly, the video games industry is one among the most important proponents of virtual reality. Support for the Oculus Rift headsets has already been jerry-rigged into games like Skyrim and grand larceny Auto, but newer games like Elite: Dangerous accompany headset support built right in. Many tried-and-true interface metaphors in gaming need to be adjusted for VR (after all, who wants to possess to select items out of a menu that takes up your entire field of vision?), but the industry has been quick to adapt because the hardware for true computer game gaming has become more widely available.
