Holographic boxes are not really holographic. :) Just a marketing thick.
Creating 3D image is a tricky thing. Hologram is pretty cool, but to make a realtime holographic display you need insane resolution to create a fine difraction grating that will create desired 3D image. And you obviously need enormous computing power to calculate that extremely high resolution images with thousands of megapixels for a decent viewport size. It is ultimately interesting thing, you could even play with it using tiny display module from cheap pico projector, but it is impossible with current tech to do something useable. And it is not that floating in the air objects everybody think about, it's more like a window with 3D objects behind. But it is still pretty cool, because of nearly infinite depth and possibility to observe created contents just like you observe the world from window. Imaginary world you could create behind that window is larger than window itself. And it is slightly foggy and opalescent (like static holograms made on photoplates you probably saw), because to create clear picture you need nearly infinite resolution. With display from pico projector you will get only single-color hologram that need laser light to produce image. It depends on method of how pixels change optical properties of surface. To create a colorful hologram you need another type of display module that change phase, not amplitude of light that bounce of pixel, much more expensive than one from pico projector.
Greetings, buddy! I often commented on HaD at the time.
Used to utilize their io project pages but they went woke so ayh dumped it. Real shame.
Yep, they go woke after sell. Pity. Had an io page too. :)
The first phase will lkely adopt the exist large television,
Probably, but the pixel count will grow proportional to square of diagonal. Since the living room limit the distance from screen you can't just make screen larger, because pixel size will destroy immersivity and perception.
room sensors and AR
AR seem to be stalled. Oculus Rift barely alive and I didn't saw any development. However AR is promising tech, I even thought about making an oversimplified bluetooth version of AR addon for safety goggles just to display multimeter measurements and similar stuff at the point of view to eliminate the distraction on multimeter display.
Yeah, that was awful. Strange they didn't spend a minimal effort when they go commercial.
Really good people still exist there.
Yes, and still from time to time I find an interesting stuff on HaD. However, real hardware hacking stuff almost disappear, replaced with tons of safety trolling and different narratives.
Funny, I noticed even kind of cancelling persons who was welcomed in past days. One of examples - Simone Giertz with her insanely funny and crazy stuff, ideas, performances and rethoric. They even posted few projects of some unknown people as new while being copies of Simone's jokes, like musical instrument made from jaws and somethinge else. Without even mentioning Simone's stuff. Can't even imagine why she was cancelled and for what.
My idea was that in simplified AR I could use LCD/LED 7segment indicators instead of matrix LCD and get rid of annoying pexilisation that way. Just to get multimeter readings in air right near the place where I stick the probes.

Aslo there are another ways to create 3D images, like rotating helix f.e. Most impressive thing I saw is this. Opensource, meanwhile - https://hackaday.io/project/180304-vvd-an-open-source-real-3d-volumetric-display I think it is closest possible thing to all that SciFi movies 3D displays.
