Built on technologies developed for smartphones, the Rift contained sensors that allow for finely grained detection of rotation and lateral movement. In other words, using internal sensors, the headset can report rotation and when it\u2019s moving forward, backward or side-to-side. What it can\u2019t do is report\u00a0<em>depth.\u00a0<\/em>That is, where within 3D space it is relative to other points.<\/p>\n<p>The original Rift\u2019s solution was to use an external tracking camera. The camera sees in the infrared spectrum and on the surface of the headset is an array of infrared lights. The camera tracks these lights and, since it knows their exact scale and pattern, can figure out exactly where the headset is relative to the camera itself.<\/p>\n<p>Combined, all of this sensor data offers accurate positioning anywhere within 3D space, at least insofar as the external tracker can see the headset. Later, products such as the HTC Vive would introduce laser-based room-scale trackers. These were mounted on the walls of a room and allowed headset positions to be tracked anywhere within their range.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Inside-Out_Tracking\"><\/span>Inside-Out Tracking<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-758838 size-full\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/09\/shutterstock_1892967694.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"An Oculus Quest 2 headset.\" width=\"650\" height=\"434\" data-crediturl=\"https:\/\/www.shutterstock.com\/image-photo\/white-new-generation-vr-headset-isolated-1892967694\" data-credittext=\"Boumen Japet\/Shutterstock.com\" 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\/white-new-generation-vr-headset-isolated-1892967694\">Boumen Japet\/Shutterstock.com<\/a><\/span><\/figcaption><\/figure>\n<p>Inside-out tracking flips the script on the traditional method we\u2019ve just described. The headset still uses camera <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a> to figure out where it is in 3D space, but the cameras are all on the headset itself.<\/p>\n<p>There are no external tracking markers, instead, sophisticated machine vision software looks for points of reference in the room around you. The software watches the movement of those reference points and then infers the headset\u2019s movement.<\/p>\n<p>The onboard cameras can do even more than that. Thanks to this spatial awareness, it\u2019s possible to create a software-based virtual barrier, so that you don\u2019t accidentally walk into a wall. This is also possible with room-scale tracking systems, but not with traditional single-camera external tracking.<\/p>\n<p>The onboard cameras can also precisely track the position of your VR controllers relative to the headset. In a brilliant further development, it\u2019s now also possible to use these onboard cameras to directly <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.youtube.com\/watch?v=2VkO-Kc3vks\">track your bare hands<\/a> for interaction within VR. No controllers needed!<\/p>\n<p>Inside-out tracking can also offer a form of \u201cmixed reality.\u201d That is, where real-world and virtual objects are blended together as one experience. The onboard headset cameras can do things like let you see your real-world keyboard when using an app like <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.oculus.com\/experiences\/quest\/2017050365004772\/\">Virtual Desktop<\/a> or bring your real-world chair into the virtual space to make it easy to sit down or get up.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"The_Advantages_of_Inside-Out_Tracking\"><\/span>The Advantages of Inside-Out Tracking<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Inside-out tracking is quickly becoming the norm for VR headsets and it\u2019s not hard to see why. This approach has numerous benefits, but the most prominent one is elegance and simplicity.<\/p>\n<p>On a headset like the\u00a0<a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.amazon.com\/Oculus-Quest-Advanced-All-One-Carrying\/dp\/B099VMT8VZ?tag=hotoge-20\">Oculus Quest 2<\/a>, there is only the headset and the two controllers. When using the Quest 2 as a tethered headset, you only need a single USB cable. Getting into VR is quick and easy. You don\u2019t have to prepare equipment, just put on the headset and play. Moving from one location to the next is equally simplified. There\u2019s no clutter and no messing around with cables, cameras, or trackers that have to be mounted. (Even if you want to use the Oculus Quest 2 as a PC VR headset, you can do it with a single USB cable\u2014or wirelessly.)<\/p>\n<p>As we mentioned above, inside-out tracking also offers new opportunities to enhance VR that go beyond positional tracking. What started out as a solution to enable true standalone VR has become what seems to be the likely future of all VR headsets.<\/p>\n<p>Inside-out tracking also solved the problem of occlusion, where the external tracking camera can\u2019t see your headset or controllers because they\u2019re obscured. One of the reasons there are at least two wall-mounted trackers with room-scale setups is to avoid anything being occluded from a sensor.<\/p>\n<div class=\"product-box\">\nBest Overall VR Headset<\/p>\n<div class=\"product-img \">\n<a rel=\"nofollow noopener\" target=\"_blank\" aria-hidden=\"true\" tabindex=\"-1\" role=\"presentation\" href=\"https:\/\/www.amazon.com\/dp\/B099VMT8VZ?tag=hotoge-20&amp;linkCode=ogi&amp;th=1&amp;psc=1\" onclick=\"fbq('track', 'Buy Button'); if (fb_t_convert){fb_t_convert();}\"><br \/>\n<img decoding=\"async\" src=\"https:\/\/m.media-amazon.com\/images\/I\/31MPSDnQmUL._SL160_.jpg\" height=\"147px\" alt=\"\" role=\"presentation\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/a>\n<\/div>\n<div class=\"product-title \">\n<a rel=\"nofollow noopener\" target=\"_blank\" title=\"Shop for Oculus Quest 2\" aria-label=\"Shop for Oculus Quest 2\" href=\"https:\/\/www.amazon.com\/dp\/B099VMT8VZ?tag=hotoge-20&amp;linkCode=ogi&amp;th=1&amp;psc=1\" onclick=\"fbq('track', 'Buy Button'); if (fb_t_convert){fb_t_convert();}\"><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Oculus_Quest_2\"><\/span>Oculus Quest 2<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><\/a><\/p>\n<p class=\"product-features\">The Oculus Quest 2 is our favorite VR headset given its ease of setup and inexpensive price. It features inside-out tracking so you don&#8217;t have to set up any separate cameras&#8212;you don&#8217;t even need a PC. (However, the Quest 2 can function as a PC VR headset, too.)<\/p>\n<\/div>\n<\/div>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"The_Downside_of_Inside-Out_Tracking\"><\/span>The Downside of Inside-Out Tracking<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Inside-out tracking is an impressive technology, but some of the most premium VR products, such as the Valve Index, still use externally-mounted trackers. If inside-out tracking is so great, why isn\u2019t it universal? The main reason comes down to precision and accuracy. The software that drives inside-out tracking has to do a lot of \u201cguessing\u201d since no algorithm is 100% accurate. This is limited by how much computational power the headset has on-board since more accurate and sophisticated machine vision technology needs more processing power. Over time, this problem is addressed simply by the march of computer performance.<\/p>\n<p>As a result, inside-out tracking on virtual reality headsets is not quite as accurate or fast as outside-in tracking, but it\u2019s catching up rapidly and is already good enough that you probably won\u2019t notice any problems while swinging a <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.reviewgeek.com\/54179\/you-can-slice-boxes-with-friends-in-the-upcoming-beat-saber-multiplayer-mode\/\">lightsaber<\/a> around or trying to win a virtual boxing match.<\/p>\n<p>\u00a0<\/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.
