In projector-based virtual reality, modeling of the real environment plays a vital role in various virtual reality applications, such as robot navigation, construction modeling, and airplane simulation. Image-based virtual reality system has been gaining popularity in computer graphics and computer vision communities. In generating realistic models, it is essential to accurately register acquired 3D data; usually, camera is used for modeling small objects at a short distance.
Although we talk about a few historical early forms of virtual reality elsewhere on the site, today virtual reality is usually implemented using computer technology. There are a range of systems that are used for this purpose, such as headsets, omni-directional treadmills and special gloves. These are used to actually stimulate our senses together in order to create the illusion of reality. https://www.aliexpress.com/item/360-Degree-Car-DVR-with-4-cameras-recording-and-Bird-Eye-View-Monitoring-Parking-Assist-System/1229624650.html
Many other companies are developing Virtual Reality headsets and other peripherals. Upcoming hardware includes the GenBasic Quad HD, StarVR StarOne, Vrgineers XTAL and Pansonite VR Headset. As more and better hardware hits the market, it will continue to power a growing ecosystem of hardware manufacturers, software developers, and content providers. https://www.aliexpress.com/item/Teclast-F5-Laptop-Intel-Gemini-Lake-N4100-Quad-Core-8GB-RAM-128GB-SSD-Windows10-360-Rotating/32901395636.html
Virtual reality is most commonly used in entertainment applications such as video gaming and 3D cinema. Consumer virtual reality headsets were first released by video game companies in the early-mid 1990s. Beginning in the 2010s, next-generation commercial tethered headsets were released by Oculus (Rift), HTC (Vive) and Sony (PlayStation VR), setting off a new wave of application development. 3D cinema has been used for sporting events, pornography, fine art, music videos and short films. Since 2015, roller coasters and theme parks have incorporated virtual reality to match visual effects with haptic feedback. https://www.aliexpress.com/item/360-Rotating-Case-Cover-for-Samsung-Galaxy-Tab3-10-1-Tablet-GT-P5200-GT-P5210-p5220/1880128544.html
The Oculus Rift was the first big name in the current wave of VR, and Oculus is still a major player. The Rift S has a higher resolution than the Vive (but not as high as the Vive Pro or, strangely, the Oculus Quest) and newer and lighter Oculus Touch motion controllers, and doesn't need external sensors to work. It does, however, need DisplayPort; if your PC only has an HDMI output, you might want to hunt for the previous Rift and deal with the extra cables.
Originally funded as a Kickstarter project in 2012, and engineered with the help of John Carmack (founder of Id Software, of Doom and Quake fame), Oculus became the early leader in Virtual Reality hardware for video games. Facebook bought Oculus in 2014, and brought the company’s high-end VR HMD to market for consumers. More recently, Oculus has seen success with the lower-price, lower-powered Oculus Go, and 2019 will see the release of multiple new iterations on the hardware, including the tethered Rift S and the stand-alone Oculus Quest. https://www.youtube.com/watch?v=hDBUkX6JQ-0&t=1s
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. https://www.aliexpress.com/item/32673925656.html
For those who aren’t hip on the trends and changes of technology, 360° video or VR (Virtual Reality) is video content that is operated much like that of Google Maps; you can look in any direction (hence 360°) at any given time. Except, unlike Google Maps, which is a 360° photo, this is video, constantly happening around you. It crosses over into being considered virtual reality — when you view these videos on a headset/goggles (or a phone in goggles most commonly) so that as you move your head and body, it changes what you’re looking at and operates in a ‘realistic’ way.
Wherever it is too dangerous, expensive or impractical to do something in reality, virtual reality is the answer. From trainee fighter pilots to medical applications trainee surgeons, virtual reality allows us to take virtual risks in order to gain real world experience. As the cost of virtual reality goes down and it becomes more mainstream you can expect more serious uses, such as education or productivity applications, to come to the fore. Virtual reality and its cousin augmented reality could substantively change the way we interface with our digital technologies. Continuing the trend of humanising our technology.
I knew the new year would come with new opportunities and new experiences, but I didn’t expect that just 1 week after New Years I would be told I had 2 weeks to create a 360° VR promo video for the construction company that does nationwide remodels of companies like McDonald’s, Starbucks, Chipotle, Chili’s, Home Depot, Walgreens, etc. This was a pretty big deal, and I had very little time to gather my thoughts, find models, locations, confirm scripts, shoot, and then edit (especially considering 360° shooting and editing was new to me). https://www.youtube.com/watch?v=CKHMq0LNmBE&t=1s
Sony’s entry into the market is the lowest powered of the three best-selling VR HMDs, but the PSVR has a big advantage over the Rift and Vive. Because it’s tethered to the Playstation 4 gaming system, there was an enormous, pre-existing user base of 10s of millions of gamers, many of whom were eager to try their hand at VR. Because that user base already had a PS4, Sony’s customers didn’t have to purchase/upgrade their computer hardware, making the PSVR the most “affordable” of the high-end HMDs. As such, the PSVR is 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 stay. https://www.youtube.com/watch?v=ss9ygQqqL2Q&t=1s
The Oculus Go is the least expensive way to jump into virtual reality. At $200 it's pricier than mobile VR headsets, but unlike those headsets, you don't need a compatible (and usually expensive flagship) smartphone to use it. The $200 investment gets you right into a Gear VR-like virtual reality experience, complete with an intuitive controller. It makes some compromises for the price, like using a dated Snapdragon 821 processor and offering only 3DOF motion tracking, but it's still enough to try out Netflix on a virtual theater screen or play Settlers of Catan in VR.
This may seems like a lot of effort, and it is! What makes the development of virtual reality worthwhile? The potential entertainment value is clear. Immersive films and video games are good examples. The entertainment industry is after all a multi-billion dollar one and consumers are always keen on novelty. Virtual reality has many other, more serious, applications as well. https://www.youtube.com/watch?v=90nDMSIgt7I&t=1s
Because of just how expensive it is to invest in high-end VR, companies have worked hard to bring us affordable VR that can run on those handy supercomputers we all carry around in our pockets. Thus, here are the best headsets you can slip your phone into. They're generally wireless and many are under £100, so it's a whole different ball game to the beasts above. Be careful though, certain devices only work with certain phones, so check before putting down any cash. https://www.aliexpress.com/item/MISECU-5-0MP-3-0MP-1-3MP-360-degree-VR-Audio-128GB-slot-Wireless-IP-Camera/32830686032.html
In Virtual Reality, the computer uses similar sensors and math. However, rather than locating a real 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. Rather than compositing virtual objects and a real scene, VR technology creates a convincing, interactive world for the user. https://www.youtube.com/watch?v=hTFe95oFnDM&t=1s
There’s a second class of Virtual Reality HMD that is really just a shell with special lens that pairs with a smartphone to deliver a VR experience. These devices can sell for almost nothing (and are often given away free), and deliver a scaled down VR experience that still approaches the immersive experiences generated by much-more expensive hardware. https://www.youtube.com/watch?v=xYz-fDX1bdM&t=1s
In 1979, Eric Howlett developed the Large Expanse, Extra Perspective (LEEP) optical system. The combined system created a stereoscopic image with a field of view wide enough to create a convincing sense of space. The users of the system have been impressed by the sensation of depth (field of view) in the scene and the corresponding realism. The original LEEP system was redesigned for NASA's Ames Research Center in 1985 for their first virtual reality installation, the VIEW (Virtual Interactive Environment Workstation) by Scott Fisher. The LEEP system provides the basis for most of the modern virtual reality headsets. https://www.aliexpress.com/item/SVPRO-hd-vr-camera-double-720p-virtual-reality-vr-box-android-phone-3d-vision-camcorder-for/32761261760.html
To a degree, I’ve made it sound harder than it actually is since software has compensated for much of this, but these were some of the questions I was asking when I was first learning. I then started learning that some standard editing procedures could still be done. For example, I can still create image masks in 360°. So in truth, I still stood behind the camera the whole time along with others and gear and then masked myself out with a separate cut of footage showing the empty room. And for the motion graphics, (I use Adobe software) the software has built-in accommodations for editing and viewing in the 3D space so as to create accurate graphics. So in truth, once I learned, it wasn’t that hard, but boy is it time-consuming.
HTC's Vive is a comprehensive package that includes a headset, two motion controllers, and two base stations for defining a "whole-room" VR area. It's technically impressive, and can track your movements in a 10-foot cube instead of just from your seat. It also includes a set of motion controllers more advanced than the PlayStation Move. PC-tethered VR systems like the Vive need plenty of power, with HTC recommending at least an Intel Core i5-4590 CPU and a GeForce GTX 970 GPU. https://www.youtube.com/watch?v=SZ0fKW5PttM&t=1s
