3D screens have really struggled to take off.<\/p>\n
Neither bulky 3D televisions that require cheap-looking glasses nor VR headsets have ever caught on in the mainstream. Movies projected in 3D have plummeted in popularity<\/a> after hitting their peak in the early 2010s.<\/p>\n But that doesn\u2019t mean there are other clever ways to trick your brain into thinking you\u2019re looking through a three-dimensional window instead of a flat screen.<\/p>\n In a fun proof of concept<\/a>, True3D Labs founder and former Meta engineer Daniel Habib explored a \u201csimpler way to watch 3D.\u201d<\/p>\n By detecting your eye position via your webcam, Habib\u2019s \u201chead-tracked \u2018Window Mode’\u201d allows you to view a scene in what feels like 3D \u2014 without having to wear glasses at all. Don\u2019t believe us? You can try out the effect inside your browser right here<\/a>.<\/p>\n \u201cMost 3D media collapses into a regular video once it lands on a phone or laptop,\u201d Habib wrote in an accompanying blog post<\/a>. \u201cInterfaces often ask people to click and drag, but in practice, most viewers are not looking to steer the camera. They want to be carried by the story.\u201d<\/p>\n 3D \u201ccan shine in venue scale installations like the Sphere in Las Vegas, yet on personal devices it rarely fits the lean back habit of watching,\u201d he argued.<\/p>\n Head-tracked \u201cWindow Mode.\u201d<\/p>\n Your front camera finds your head.
