You may remember the <a href=\"\/\/history-computer.com\/the-rise-and-fall-of-3d-tvs\/&quot;\" target=\"&quot;_blank&quot;\" rel=\"&quot;noopener&quot; noopener noreferrer\">first attempt at 3D televisions<\/a> was a flop \u2013 nobody wanted to wear silly glasses at home and the quality wasn\u2019t always great. This was known as \u2018passive 3D\u2019.<\/p>\n<p>Things are different now: the latest 3D screens are \u2018active 3D\u2019. A camera with some clever <a href=\"&quot;https:\/\/www.sciencefocus.com\/future-technology\/artificial-intelligence-ai\/&quot;\">AI<\/a> software monitors the position of your eyes and presents each one with a subtly different view, calculated to give you the perfect illusion of depth.<\/p>\n<p>The screens are able to present different images to your left and right eye by using a special lenticular lens layer that enables the light to be directed to the correct places, even if you move to a different position. Because it works by tracking your eyes, you don\u2019t need to wear special glasses. Some of the screens will even detect multiple people at once and show each of them the view in 3D, albeit at a reduced resolution. The first laptops and televisions with this technology are coming out now.<\/p>\n<p>It\u2019s still a little hard to make holograms that feel solid, but researchers have shown that <a href=\"\/\/physics.nyu.edu\/grierlab\/acoustokinetic03c\/&quot;\" target=\"&quot;_blank&quot;\" rel=\"&quot;noopener&quot; noopener noreferrer\">low-frequency audio waves<\/a> can be directed such that they induce force, in a method known as audio haptics.<\/p>\n<p>In 2021, scientists at the University of Glasgow created a system that <a href=\"\/\/www.gla.ac.uk\/news\/archiveofnews\/2021\/september\/headline_809302_en.html&quot;\" target=\"&quot;_blank&quot;\" rel=\"&quot;noopener&quot; noopener noreferrer\">tracks the position of your hand and then carefully pushes air<\/a> with the right force in response to its movement when you interact with the virtual object. The result is that you feel as though you\u2019re touching the 3D image.<\/p>\n<p>Not quite a force field, but pretty good!<\/p>\n<p><strong>Read more:<\/strong><\/p>\n<ul><li><a href=\"&quot;https:\/\/www.sciencefocus.com\/future-technology\/when-will-we-see-star-wars-tech-in-the-real-world\/&quot;\">When will we see Star Wars tech in the real world?<\/a><\/li>\n<li><a href=\"&quot;https:\/\/www.sciencefocus.com\/the-human-body\/why-cant-we-see-in-more-dimensions-than-3d\/&quot;\">Why can\u2019t we see in more dimensions than 3D?<\/a><\/li>\n<li><a href=\"&quot;https:\/\/www.sciencefocus.com\/future-technology\/does-your-brain-adjust-to-the-3d-ness-of-a-3d-film\/&quot;\">Does your brain adjust to the 3D-ness of a 3D film?<\/a><\/li>\n<li><a href=\"&quot;https:\/\/www.sciencefocus.com\/space\/dr-erin-macdonald-is-there-any-science-in-star-trek\/&quot;\">Dr Erin Macdonald: Is there science in Star Trek?<\/a><\/li>\n<\/ul>\n<p><strong>Asked by: Ann Hoffman, Swindon<\/strong><\/p>\n<p><em>To submit your questions email us at questions@sciencefocus.com (don\u2019t forget to include your name and location)<\/em><\/p> <\/body><\/html>\n<hr class=\"no-tts wp-block-separator\"\/>","protected":false},"excerpt":{"rendered":"<p> Step into the future as we take a closer look at the holodecks on Star Trek&#8230; they&#8217;re closer than you might think. <\/p>\n","protected":false},"author":24,"featured_media":28693,"template":"","categories":[30],"acf":{"readingTimeMinutes":"2"},"uagb_featured_image_src":{"full":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/06\/power-up-the-holodeck-how-interactive-holograms-could-soon-be-a-reality.jpg",1280,545,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/06\/power-up-the-holodeck-how-interactive-holograms-could-soon-be-a-reality-150x150.jpg",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/06\/power-up-the-holodeck-how-interactive-holograms-could-soon-be-a-reality-300x128.jpg",300,128,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/06\/power-up-the-holodeck-how-interactive-holograms-could-soon-be-a-reality-768x327.jpg",768,327,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/06\/power-up-the-holodeck-how-interactive-holograms-could-soon-be-a-reality-1024x436.jpg",800,341,true],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/06\/power-up-the-holodeck-how-interactive-holograms-could-soon-be-a-reality.jpg",1280,545,false],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/42\/2023\/06\/power-up-the-holodeck-how-interactive-holograms-could-soon-be-a-reality.jpg",1280,545,false]},"uagb_author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/author\/importmanagerhubsprylab-com\/"},"uagb_comment_info":0,"uagb_excerpt":"Step into the future as we take a closer look at the holodecks on Star Trek... they're closer than you might think.","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/rss_feed\/28692"}],"collection":[{"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/rss_feed"}],"about":[{"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/types\/rss_feed"}],"author":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/users\/24"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/media\/28693"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/media?parent=28692"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcsciencefocus\/wp-json\/wp\/v2\/categories?post=28692"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
