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.
The NBA has long been interested in virtual reality and 360 filmmaking, so it's no surprise that it would decide to take one of the most exciting events on All Star Weekend, the Dunk Contest, and turn it into a 360 video. In this case, you'll get to see all the dunks of winner Donovan Mitchell. Sit courtside as this mountain of a man charges to the hoop and seemingly defies the laws of physics. https://www.aliexpress.com/item/1PCS-Transmission-Solenoid-Valve-OEM-46313-3B030-463133B030-9360930002/32835810874.html
In 1992, Nicole Stenger created Angels, the first real-time interactive immersive movie where the interaction was facilitated with a dataglove and high-resolution goggles. That same year, Louis Rosenberg created the virtual fixtures system at the U.S. Air Force's Armstrong Labs using a full upper-body exoskeleton, enabling a physically realistic mixed reality in 3D. The system enabled the overlay of physically real 3D virtual objects registered with a user's direct view of the real world, producing the first true augmented reality experience enabling sight, sound, and touch.
The HTC Vive has been one of the best VR HMDs on the market since its consumer release back in 2016. Manufactured by HTC, the Vive was the first VR HMD to support SteamVR. The Vive has been locked in fierce competition with the Oculus Rift since release, as both headsets aimed at the same top end of the VR enthusiast market. The Vive has proven itself a durable workhorse for enterprise solutions, while also delivering one of the best consumer VR experiences available. The Vive was first released back in 2016, and has gone through several iterations, with the addition of a wireless module. The Vive Pro came out in 2018 and the Vive Pro Eye and the HTC Vive Cosmos are both slated for release in the second half of 2019.
In 1991, Sega announced the Sega VR headset for arcade games and the Mega Drive console. It used LCD screens in the visor, stereo headphones, and inertial sensors that allowed the system to track and react to the movements of the user's head. In the same year, Virtuality launched and went on to become the first mass-produced, networked, multiplayer VR entertainment system that was released in many countries, including a dedicated VR arcade at Embarcadero Center. Costing up to $73,000 per multi-pod Virtuality system, they featured headsets and exoskeleton gloves that gave one of the first "immersive" VR experiences. https://www.youtube.com/channel/UCA0McsiXWJZu11MsiDdXvlw
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/channel/UCQ3o8kIMsenaKpQE0x3a3Cw
This is more difficult than it sounds, since our senses and brains are evolved to provide us with a finely synchronised and mediated experience. If anything is even a little off we can usually tell. This is where you’ll hear terms such as immersiveness and realism enter the conversation. These issues that divide convincing or enjoyable virtual reality experiences from jarring or unpleasant ones are partly technical and partly conceptual. Virtual reality technology needs to take our physiology into account. For example, the human visual field does not look like a video frame. We have (more or less) 180 degrees of vision and although you are not always consciously aware of your peripheral vision, if it were gone you’d notice. Similarly when what your eyes and the vestibular system in your ears tell you are in conflict it can cause motion sickness. Which is what happens to some people on boats or when they read while in a car. https://www.aliexpress.com/item/SDETER-Bulb-Lamp-Wireless-IP-Camera-Wifi-960P-Panoramic-FishEye-Home-Security-CCTV-Camera-360-Degree/32839173184.html
Microsoft HoloLens is shaping up to be another formidable competitor in the HMD market. Unlike VR tech, Microsoft based their display on holographic technology. The original Hololens was more proof of concept than consumer device, and the recently announced Hololens 2 is again eschewing the public in favor of enterprise/government uses. The Hololens 2 will feature upgraded visuals, including a much-expanded field of view — music to fans of the original device, who settled on the limited FOV as the main drawback of the device. https://www.youtube.com/watch?v=FNq-8bWfAwQ&t=1s
Virtual reality (VR) is an experience taking place within simulated and immersive environments that can be similar to or completely different from the real world. Applications of virtual reality can include entertainment (i.e. gaming) and educational purposes (i.e. medical or military training). Other, distinct types of VR style technology include augmented reality and mixed reality.
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.aliexpress.com/item/New-360-Degree-Reflective-Prism-Set-for-Leica-ATR-Total-station-Replaces-MPR122/32918809914.html
Virtual Reality’s most immediately-recognizable component is the head-mounted display (HMD). Human beings are visual creatures, and display technology is often the single biggest difference between immersive Virtual Reality systems and traditional user interfaces. For instance, CAVE automatic virtual environments actively display virtual content onto room-sized screens. While they are fun for people in universities and big labs, consumer and industrial wearables are the wild west. https://www.youtube.com/watch?v=gc9H7UFzpPw&t=1s
Magic Leap has been an investor and media darling since 2014, when Google dumped $540 million in seed money into its sizable coffers. The company has been a source of much fascination and hand-wringing by industry observers ever since. Magic Leap fed the public appetite for information with a string of vaporware demos before finally unveiling the Magic Leap One in 2018. Instead of a magical breakthrough device, the Magic Leap One was more of an updated Hololens, which produced good (but not great) 3D imagery that mixed decently (but not spectacularly) with the real world. The Magic Leap One remains more of a developer tool in search of a consumer application — much like the Hololens. Despite all the doubts now surrounding the company and their technology, Magic Leap’s presence in the industry continues to challenge well-established brands, making them an unusual, but a noteworthy company. https://www.youtube.com/watch?v=Bg_Q7KYWG1g&t=1s
Everything that we know about our reality comes by way of our senses. In other words, our entire experience of reality is simply a combination of sensory information and our brains sense-making mechanisms for that information. It stands to reason then, that if you can present your senses with made-up information, your perception of reality would also change in response to it. You would be presented with a version of reality that isn’t really there, but from your perspective it would be perceived as real. Something we would refer to as a virtual reality. https://www.aliexpress.com/item/OSSC-HDMI-Converter-Kit-for-Retro-Game-Console-PlayStation-1-2-Xbox-one-360-Atari-Series/32969633292.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
Google and Samsung were the biggest names in mobile VR, with Google Cardboard and the Daydream View, and Samsung's line of Gear VR headsets. They respectively worked with Google's and Samsung's flagship phones, like the Pixel 3 and the Galaxy S9. However, both companies have been very quiet over the last year or so about the category, and we've yet to see a Gear VR headset compatible with the Galaxy S10 series.
That same year, Carolina Cruz-Neira, Daniel J. Sandin and Thomas A. DeFanti from the Electronic Visualization Laboratory created the first cubic immersive room, the Cave automatic virtual environment (CAVE). Developed as Cruz-Neira's PhD thesis, it involved a multi-projected environment, similar to the holodeck, allowing people to see their own bodies in relation to others in the room. Antonio Medina, a MIT graduate and NASA scientist, designed a virtual reality system to "drive" Mars rovers from Earth in apparent real time despite the substantial delay of Mars-Earth-Mars signals. https://www.youtube.com/watch?v=JsC9ZHi79jo&t=1s
Google and Samsung still offer phone-based VR headsets in the form of the Daydream View and the Gear VR, and even Nintendo has gotten into the game with its Labo VR Kit for the Nintendo Switch. However, these shell-like headsets, which require a phone or some other device physically inserted into them, feel like novelties next to more powerful headsets that can provide more immersive experiences.
To create a feeling of immersion, special output devices are needed to display virtual worlds. Well-known formats include head-mounted displays or the CAVE. In order to convey a spatial impression, two images are generated and displayed from different perspectives (stereo projection). There are different technologies available to bring the respective image to the right eye. A distinction is made between active (e.g. shutter glasses) and passive technologies (e.g. polarizing filters or Infitec). https://www.youtube.com/watch?v=rrZuH2MtLcs&t=1s
The newest breed of mobile headsets can also be considered "tethered," because instead of inserting your phone into the headset itself, you physically connect your phone with a USB-C cable. Qualcomm has been emphasizing the VR and augmented reality capabilities of its Snapdragon 855 processor, and is promoting a new ecosystem of XR viewers (including both AR and VR devices). These use the aforementioned USB-C connection to run all processing from a smartphone, while keeping the display technology built separately into the VR headset or AR glasses. https://www.youtube.com/watch?v=jLtcPTm5dTg&t=1s
