I remember being awestruck by that 2007 Wii video, and spent a lot of time playing around with the remote after that. That, and the Xbox Kinect, were really cool tools. Why hasn't those concepts seen more widespread use outside gaming? As for 3D, I also remember seeing a TV at Toshiba HQ in 2013 or so that had 3D without glasses, and even worked for multiple people. No idea how.

Sony has a head tracking OLED sub-display for VR/3D content creation in office setups, Looking Glass was doing crowd funding recently for an apparently very well done lenticular digital photo frame, those two comes off top of my head.

Lenticular 3D limits resolution to a fraction divided by double of the number of viewpoints in an axis, e.g. a 4K by 2K panel with 10 viewpoint along its width means effective resolution is 400 by 2K. Okay for demos but not practical atm.

> Why hasn't those concepts seen more widespread use outside gaming? I wrote my master thesis on designing gesture interfaces (of the Xbox Kinect type) back in 2012, here's my two cents: First of all, gesture detection still isn't reliable enough for serious input. Missing a beat one in a hundred times is acceptable in gaming settings (and even then only in more "casual" environments like party games), but for seriou…

Back in 2012 I did some building on ZSpace[0] and the that setup still feels like the sweet spot: Physical keyboard, physical pen (with virtual extension), physical glasses to detect head position for parallax, 3D environment to play and create in. The _visual_ feedback from moving your head and rotating objects with the pen were extremely low-latency. Gesture detection is still nowhere near that level of fidelity bu…

Cool, that sounds a lot like Bill Buxton's experiments with two-handed input, but in VR!

that was a nice way of saying it

I don't know what's the "it" that you mean. I simply think that this piece of work would greatly benefit from some image or video examples of the technique being applied in practice, especially to help people who are not very acquainted with 2D and 3D image processing. For instance, I can only imagine right now how this technique works; I'd rather not leave that to my very imperfect imagination.

I believe that the parent post is saying they appreciate how you expressed a particular sentiment (same as [0]) in a polite and constructive way, given that the sentiment is much more easily expressed with a negative framing.

I first saw that in person on a pinball machine like this: https://www.youtube.com/watch?v=64e7TQ5uj8g

The effect is fantastic.
