It works by tracking or predicting the position of the eye so that the portion of the scene that the wearer is looking at is prioritized for high-quality rendering.<\/p>\n<p>This means that rather than rendering an entire scene at a fixed or even dynamic resolution, the rendering budget can be better spent on just the part of the image that a wearer is looking at. The very edge of the wearer\u2019s field of view may see a reduction in resolution or other image-enhancing techniques like anti-aliasing since they aren\u2019t in focus.<\/p>\n<figure style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-779651\" data-pagespeed-lazy-src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2022\/01\/tobii_foveated_rendering.png?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"Tobii Eye Tracking Foveated Rendering demo\" width=\"650\" height=\"303\" 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\">Tobii<\/span><\/figcaption><\/figure>\n<p>The technique works best when paired with a camera inside of the headset to accurately track the position of the eye. A less sophisticated method involves predicting the position of the eye, known as \u201cfixed foveated rendering\u201d but naturally this has its limitations.<\/p>\n<p>Not only is the technique more efficient in terms of hardware utilization, but it is also said to provide a more \u201clifelike\u201d VR experience, better mirroring the way our eyes perceive the world.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Which_Devices_Support_Foveated_Rendering\"><\/span>Which Devices Support Foveated Rendering?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Foveated rendering first <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>eared on a headset called <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/en.wikipedia.org\/wiki\/Fove\">Fove<\/a> in 2014.

Finnish company Varjo also produces a range of headsets including the <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/varjo.com\/products\/xr-3\/\">XR-3<\/a> and <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/varjo.com\/products\/vr-3\/\">VR-3<\/a> which track eye position for true foveated rendering implementation.<\/p>\n<p>Most notably, the upcoming PlayStation VR2 which is expected to launch sometime in 2022 will include eye-tracking and foveated rendering. This move by Sony will likely bring the <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a> into the mainstream, though given the impressive specifications of the device it\u2019s not clear at what price this will be.<\/p>\n<p>Some headsets offer fixed foveated rendering which helps performance but cannot compete with solutions that use eye-tracking. This includes the Oculus Quest, a budget VR offering, which added the feature to the headset software development kit (SDK) allowing developers to implement it into their <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/game\/\" data-internallinksmanager029f6b8e52c=\"7\" title=\"Game\" target=\"_blank\" rel=\"noopener\">game<\/a>s.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"A_Big_Deal_for_VR_Going_Forward\"><\/span>A Big Deal for VR Going Forward<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One of the biggest barriers to entry in terms of virtual reality adoption is the massive cost involved in both rendering budget and investment from the wearer. Foveated rendering can at least alleviate the strain on the hardware by prioritizing the center field of vision. This could in theory lower the barrier to entry in terms of minimum system requirements, allowing more people to take up the hobby.<\/p>\n<p>Sony\u2019s commitment to foveated rendering with the PSVR 2 is not only great <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a> for owners of Sony consoles, but it could also have a lasting positive effect on the VR market in <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">general<\/a>.<\/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.
