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
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.
No, this isn't a VR-ready look into the huge court case between Uber and Waymo. It's a 360 video that lets you see how Google's fleet of self-driving cars sees the world. You'll "sit" right on top of the car's LIDAR systems and view the world as machine vision sees the world, complete with lots of little graphics pointing out absolutely everything in sight. There is no better way to learn about self-driving technology than this. https://www.youtube.com/watch?v=8IQbF0IK-f4&t=1s
The Vuzix Blade are the first Mixed Reality glasses to look like, well, glasses. A close cousin of the “Buddy Holly” style or those 3D spectacles you get at the movie theater, Vuzix Blade moves many core smartphone features from the touchscreen to in front of your face. Thing Uber ordering, GPS, fitness tracking, weather updates, messages, and more. Vuzix Blade is compatible with iOS and Android devices, and will set you back a cool $999.
The two images are then stitched together on the computer just after import. The stitched image (looks like the thumbnail for the above video) is called “equirectangular” format and looks like all 360° got compressed into a single 16:9 frame. Viewers and websites such as YouTube and Vimeo can detect this kind of footage in the file metadata and display it in VR form.
As of the end of 2018, the three best selling Virtual Reality headsets were Sony’s PlayStation VR (PSVR), Facebook’s Oculus Rift and the HTC Vive. This was not a surprise, seeing as the same three HMDs had also been best sellers in 2017. 2019 sees the VR landscape broadening with Google, HP, Lenovo, and others looking to grab a piece of the still-burgeoning market.
It's also got a bunch of doodads to help you customise your mobile experience. Adjust the lenses all you want, click two buttons to interact with your content; pop out the front window in case you ever need to use it for mixed/augmented reality purposes. Speaking of which, Merge now also sells the AR Merge cube, which lets you put mixed reality experiences in the palm of your hand.
The Vive Pro sports a 2,880 x 1,600 resolution on a dual-OLED display, up from the Vive's 2,160 x 1,200 resolution. There's also dual cameras on the front that'll help track your hands and a 90Hz refresh rate with 70 sensors, giving you 360-degree head-tracking. It's not a leap to say that the Vive Pro is a monster. This is easily the most advanced VR headset out there, but it's also incredibly expensive, sitting at £799. If you don't need that added clarity, the Vive has all the same tricks. https://www.youtube.com/watch?v=HwolI3DQFhI&t=1s
Virtual Reality (VR) is the use of computer technology to create a simulated environment. Unlike traditional user interfaces, VR places the user inside an experience. Instead of viewing a screen in front of them, users are immersed and able to interact with 3D worlds. By simulating as many senses as possible, such as vision, hearing, touch, even smell, the computer is transformed into a gatekeeper to this artificial world. The only limits to near-real VR experiences are the availability of content and cheap computing power.
Morton Heilig wrote in the 1950s of an "Experience Theatre" that could encompass all the senses in an effective manner, thus drawing the viewer into the onscreen activity. He built a prototype of his vision dubbed the Sensorama in 1962, along with five short films to be displayed in it while engaging multiple senses (sight, sound, smell, and touch). Predating digital computing, the Sensorama was a mechanical device. Heilig also developed what he referred to as the "Telesphere Mask" (patented in 1960). The patent application described the device as "a telescopic television apparatus for individual use...The spectator is given a complete sensation of reality, i.e. moving three dimensional images which may be in colour, with 100% peripheral vision, binaural sound, scents and air breezes."
A virtual environment should provide the appropriate responses – in real time- as the person explores their surroundings. The problems arise when there is a delay between the person’s actions and system response or latency which then disrupts their experience. The person becomes aware that they are in an artificial environment and adjusts their behaviour accordingly which results in a stilted, mechanical form of interaction. https://www.youtube.com/watch?v=6-KXHJfrCus&t=1s
If you have compatible phones, these headsets offer functional 3DOF VR experiences for just $60 to $130. You slide your phone into one, put it on your head, and start tapping away with the included remote. It's interesting, but underwhelming next to tethered and 6DOF standalone VR experiences. Perhaps we'll see some 6DOF updates, but we aren't counting on it. https://www.youtube.com/watch?v=mkl-8pxN7MU&t=1s
In addition, there are conceptual and philosophical considerations and implications associated with the use of virtual reality. What the phrase "virtual reality" means or refers to can be ambiguous. Mychilo S. Cline argued in 2005 that through virtual reality techniques will be developed to influence human behavior, interpersonal communication, and cognition.
Independent production of VR images and video has increased by the development of omnidirectional cameras, also known as 360-degree cameras or VR cameras, that have the ability to record 360 interactive photography, although at low-resolutions or in highly-compressed formats for online streaming of 360 video. In contrast, photogrammetry is increasingly used to combine several high-resolution photographs for the creation of detailed 3D objects and environments in VR applications. https://www.aliexpress.com/item/1-2-Inch-Rotating-Sprinkler-360-Degree-Adjustable-Sprinkler-Irrigation-Watering-Garden-Spray-Nozzle-1-Pc/32849703229.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
The Lenovo Mirage Solo is the Google Daydream version of the Oculus Quest, but it doesn't quite hit the mark. It has the same Snapdragon 835 processor and outward-facing cameras for 6DOF position tracking for the headset itself, but it includes only a single 3DOF motion controller, which severely limits its capabilities. It feels like a half-step between the Go and the Quest, using Google's Daydream platform instead of Oculus, and simply isn't as compelling as the other standalone headsets because of it. https://www.aliexpress.com/item/Magicsee-C1-360-Camera-Panoramic-Dual-Lens-Mini-VR-Camera-360-Degrees-F2-0-1080P-30fps/32714156264.html
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.youtube.com/watch?v=rTM8vXtdIUA&t=1s
