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
In 1999, entrepreneur Philip Rosedale formed Linden Lab with an initial focus on the development of VR hardware. In its earliest form, the company struggled to produce a commercial version of "The Rig", which was realized in prototype form as a clunky steel contraption with several computer monitors that users could wear on their shoulders. The concept was later adapted into the personal computer-based, 3D virtual world program Second Life. https://www.aliexpress.com/item/New-Style-Camera-360-4k-360-degree-Panoramic-VR-Camera-Build-in-WiFi-Mini-Sports-Action/32702459981.html
The Oculus Touch controllers have made a world of difference since their arrival. Compared to the other headsets' controllers, they're our favourite – they conform to your hand and allow for some finger recognition, like a thumbs-up. Not just that, but when it comes to games Oculus has come on leaps and bounds. That's been largely helped by some developer cash injections from Facebook, giving us quality, polished titles like Lone Echo and Robo Recall. Room-scale support has been added too, though you'll need to purchase at least one additional sensor to get it to Vive-level tracking, and even then the Vive tracking experience is a little better in our experience. https://www.youtube.com/watch?v=jIxQXGTl_mo&t=1s
It really is that simple. You do need the companion app on your phone first, which will make you log in. You'll also have to grant location access and pair the Go to your Wi-Fi. Once you've done that, and inserted and paired your controller, you're all good to go. There will be a little video that tells you a bit about safety, but that's it. That's how simple it is to set up.
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=EqcdU9wT5EI&t=1s
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. https://www.aliexpress.com/item/Insta360-Nano-360-Degree-Panoramic-Camera-3K-HD-Mini-VR-Camera-210-Degree-Dual-Wide-Angle/32697639175.html
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=OCa6_lLUfzw&t=1s
Leap Motion has been around for a while but now it's got a new lease of life as a VR peripheral compatible with both the Rift and HTC Vive. It attaches with an add-on mounted to the front of the headset and adds hand gesture controls to your virtual reality gaming. It's super precise, tracking each finger – the question is, how precise are your dumb human hands? https://www.youtube.com/watch?v=nEi6u2lAYHg&t=1s
Virtual reality is the creation of a virtual environment presented to our senses in such a way that we experience it as if we were really there. It uses a host of technologies to achieve this goal and is a technically complex feat that has to account for our perception and cognition. It has both entertainment and serious uses. The technology is becoming cheaper and more widespread. We can expect to see many more innovative uses for the technology in the future and perhaps a fundamental way in which we communicate and work thanks to the possibilities of virtual reality.
With a multiplicity of emerging hardware and software options, the future of wearables is unfolding but yet unknown. Concepts such as the HTC Vive Pro Eye, Oculus Quest and Playstation VR are leading the way, but there are also players like Google, Apple, Samsung, Lenovo and others who may surprise the industry with new levels of immersion and usability. Whomever comes out ahead, the simplicity of buying a helmet-sized device that can work in a living-room, office, or factory floor has made HMDs center stage when it comes to Virtual Reality technologies.
Naming discrepancies aside, the concept remains the same - using computer technology to create a simulated, three-dimensional world that a user can manipulate and explore while feeling as if he were in that world. Scientists, theorists and engineers have designed dozens of devices and applications to achieve this goal. Opinions differ on what exactly constitutes a true VR experience, but in general it should include: https://www.youtube.com/watch?v=8lsB-P8nGSM&t=1s
