Whether it\u2019s at your desk, in a park, or anywhere else you might find yourself on a given day, you don\u2019t question whether you\u2019re really there, right? You feel physically present and accept the reality of it at a subconscious level.<\/p>\n<p>That\u2019s exactly what VR creators want to achieve with the experiences they design. For VR to be compelling, your brain needs to accept the virtual world as real. At least to the extent that you\u2019re actually there, not that the things you\u2019re seeing are necessarily real, which is another discussion.<\/p>\n<p>\u201cPresence\u201d is something that\u2019s hard to put into words, but as an experience it\u2019s unmistakable. It\u2019s like looking at a 3D \u201c<a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.magiceye.com\/stwkdisp.htm\">magic eye<\/a>\u201d picture that suddenly snaps into focus. It\u2019s a result of subconscious processes that are part of the way your senses and brain construct your reality.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Our_Brains_Construct_Reality\"><\/span>Our Brains Construct Reality<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>This raises an interesting fact about how we perceive the real world. Which is to say, we don\u2019t really do that. The world you perceive around you and the feeling of being present that\u2019s part and parcel of it isn\u2019t the real world at all. Sure, it\u2019s\u00a0<em>based\u00a0<\/em>on the real world, but what you perceive is a reconstruction of reality. You don\u2019t even live in real-time! Since sensory processing takes time to h<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>en, your perceptions are always <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/theconversation.com\/what-youre-seeing-right-now-is-the-past-so-your-brain-is-predicting-the-present-131913\">a few milliseconds behind<\/a> whatever actually happened in the world around you.<\/p>\n<p>It\u2019s also not a one-way process. Our previous experiences and knowledge of the world affect what things look like to us. A brain has limited capacity, so it\u2019s always trying to take shortcuts, which includes fudging the details of what we perceive based on what we\u2019ve seen or experienced before.<\/p>\n<p>We can even lose our sense of presence in real life, which is one of the major symptoms found in psychological\u00a0<em>dissociation\u00a0<\/em>\u2013 a detachment from reality.<\/p>\n<p>This is good <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a> for VR creators, however, since we know that our brains generate a sense of presence based on what our sensory organs are currently reporting and our past expectations and experiences. So, in theory, all you have to do is present the brain with the right sensory inputs and design your VR experience so it doesn\u2019t violate the user\u2019s expectations of reality. Well, at least not by accident.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"How_VR_Tricks_Your_Brain_Into_Feeling_Present\"><\/span>How VR Tricks Your Brain Into Feeling Present<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-776821 size-full\" data-pagespeed-lazy-src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/12\/vr-winter.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"A woman wearing a VR headset to play a winter sports game.\" width=\"650\" height=\"327\" data-crediturl=\"https:\/\/www.shutterstock.com\/image-photo\/woman-uses-vr-headset-go-snowboarding-1916289530\" data-credittext=\"nuclear_lily\/Shutterstock.com\" src=\"\/pagespeed_static\/1.JiBnMqyl6S.gif\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\"><span class=\"imagecredit\"><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.shutterstock.com\/image-photo\/woman-uses-vr-headset-go-snowboarding-1916289530\">nuclear_lily\/Shutterstock.com<\/a><\/span><\/figcaption><\/figure>\n<p>While that sounds easy on paper, the real challenge was figuring out what exactly your brain needs before that feeling of presence is triggered. The pioneering work that companies such as Oculus have done, along with years of academic research on VR and related areas has led to the point where a formula for presence more or less exists.<\/p>\n<p>It turns out that you don\u2019t have to 100% replicate the real world in order to trick the brain into feeling presence. With a few key requirements met, you can feel a sense of presence with an affordable headset (such as the Quest 2) and relatively simple graphics.<\/p>\n<p>First, there\u2019s the quality of tracking. That is, how the VR software tracks the physical position of your body in virtual space. Tracking has to be in all axes of 3D space. Also known as \u201c6DoF\u201d or six degrees of freedom. Tracking accuracy has to be within 1mm of your true position within 3D space. There can be no \u201cjitter\u201d, where the VR world jumps between slightly different positions, causing the image to shake. A stable image is essential. You also need this accurate tracking in a relatively large and comfortable amount of space.<\/p>\n<p>Perhaps one of the most important requirements for presence is low latency. In other words, the VR world must react to your movements so quickly that it feels like real-time. According to John Carmack, a key technologist in the development of modern VR, <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.pcgamesn.com\/virtual-reality-john-carmacks-battle-20-millisecond-latency\">20ms of motion-to-photon latency<\/a> is the dividing line for presence. This means that from where you initiate a movement to where the photons reflecting that movement in the VR world hit your retinas can take no longer than 20ms.<\/p>\n<p>Image quality matters, too, but not in terms of rendering fidelity or quality. Instead, a low-persistence display that combat\u2019s flat-panel blur and at least a 90Hz refresh rate are important factors in making presence possible. The physical resolution of the screens also needs to be high enough that the user\u2019s eyes can\u2019t see the pixel structure of the display.\u00a0 Finally, the horizontal field of view has to be 90-degrees or wider.<\/p>\n<p>This isn\u2019t a comprehensive laundry list of requirements for presence, but they are the most important ones. Achieving all of this is something as compact as a modern VR headset\u00a0like the <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.amazon.com\/Oculus-Quest-Advanced-All-One-Virtual\/dp\/B099VMT8VZ?tag=hotoge-20\">Oculus Quest 2<\/a> is a miracle of engineering!<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Presence_Is_a_Persistent_Challenge\"><\/span>Presence Is a Persistent Challenge<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>While VR engineers and researchers have cracked the code when it comes to minimum presence requirements, that doesn\u2019t mean there isn\u2019t a lot of work left to do. There\u2019s plenty of scope to enrich the sensory experience of VR. Better haptics and adding sensory input for smell and taste are some examples. Making headsets less obtrusive and offering a complete field of view is also high on the list of goals for VR development. VR has finally brought a sense of presence to the table, but it\u2019s early days yet.<\/p>\n<\/div>\n<p><script>\n setTimeout(function(){\n  !function(f,b,e,v,n,t,s)\n  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?\n  n.callMethod.apply(n,arguments):n.queue.push(arguments)};\n  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';\n  n.queue=[];t=b.createElement(e);t.async=!0;\n  t.src=v;s=b.getElementsByTagName(e)[0];\n  s.parentNode.insertBefore(t,s) } (window, document,'script',\n  'https:\/\/connect.facebook.net\/en_US\/fbevents.js');\n   fbq('init', '335401813750447');\n   fbq('track', 'PageView');\n  },3000);\n<\/script><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
