For now, the lab version has an anemic field of view \u2014 just 11.7 degrees in the lab, far smaller than a Magic Leap 2 or even a Microsoft HoloLens. <\/p>\n<\/div>\n
But Stanford\u2019s Computational Imaging Lab has an entire page with visual aid after visual aid<\/a> that suggests it could be onto something special: a thinner stack of holographic components that could nearly fit into standard glasses frames, and be trained to project realistic, full-color, moving 3D images that appear at varying depths.<\/p>\n<\/div>\n Like other AR eyeglasses, they use waveguides, which are a component that guides light through glasses and into the wearer\u2019s eyes. But researchers say they\u2019ve developed a unique \u201cnanophotonic metasurface waveguide\u201d that can \u201celiminate the need for bulky collimation optics,\u201d and a \u201clearned physical waveguide model\u201d that uses AI algorithms to drastically improve image quality. The study says the models \u201care automatically calibrated using camera feedback\u201d.<\/p>\n<\/div>\n Although the Stanford tech is currently just a prototype, with working models that appear to be attached to a bench and 3D-printed frames, the researchers are looking to disrupt the current spatial computing market that also includes bulky passthrough mixed reality<\/a> headsets like Apple\u2019s Vision Pro, Meta\u2019s Quest 3, and others. <\/p>\n<\/div>\n Postdoctoral researcher Gun-Yeal Lee, who helped write the paper published in Nature<\/em><\/a>, says there\u2019s no other AR system that compares both in capability and compactness. <\/p>\n<\/div>\n
