After all the hype, it seems almost anti-climactic that the demo is so similar to what Pranav Mistry showed with SixthSense in 2009<p><a href="https://en.wikipedia.org/wiki/SixthSense?wprov=sfti1" rel="nofollow">https://en.wikipedia.org/wiki/SixthSense?wprov=sfti1</a><p><a href="https://youtu.be/YrtANPtnhyg" rel="nofollow">https://youtu.be/YrtANPtnhyg</a><p>Granted, over a decade later a lot of the tech is in place to do this at a higher fidelity.<p>But the same core issues remain: privacy.<p>People don’t want what they’re up to, to be projected for everyone to see at all times, whether that’s visual or audio.<p>Yes, people can look over our shoulders today to see our phones, but it’s much smaller, and therefore harder to snoop on.<p>the same goes for audio, I don’t want to blast my audio out so everyone can hear either.<p>Imho this will be an interesting novelty stepping stone on the way to more practical waveguide displays in glasses. Where I can have higher privacy, with audio projected to my ears. Yes, people can see the waveguide activations and hear the audio, but they’d have to be incredibly close to discern the same information as this, just due to proximity/scale
