Ackerman wrote about their latest development, first explaining what Aerial Burton had accomplished. The method involves "a laser that scans through a volume of air very quickly, firing tens or hundreds of thousands of times per second to create a sequence of short-lived (nanosecond-scale) voxels that create the effect of a moving image." Ackerman noted that a nanosecond-scale plasma burst contains "a significant amount of energy; you don't want to go walking through one of these displays, because it will burn you."[/quote]

[QUOTE=FingerSpazem;48085774]Lightsabers are on the horizon[/QUOTE] It's not new that lasers burn you :v:
Oh fuck, that's actually amazing. Anyone got a link to the study? I'm interested in the scalability.
Feels like we're really in the period where science fiction is becoming real life
Jesus christ, the music in that video is so bad.
Nice, now make one that isnt rediculously tiny
I imagine a room with a large hologram would become quite hot? [editline]30th June 2015[/editline] Or what temperature is the plasma at?

[QUOTE=Xyrec;48086019]Jesus christ, the music in that video is so bad.[/QUOTE] lol i had to rewatch the video because I honestly couldn't remember, because you said it was so bad I was expecting some kind of blaring dubstep or something but what I got instead was just some neutral commercial music that I have no strong opinion about either way
fuckin future man
[QUOTE=CLungcancer;48087493]You wanna die?[/QUOTE] gotta admit it'd be a pretty rad way to go out first person to die from a hologram
[QUOTE=CLungcancer;48087493]You wanna die?[/QUOTE] People are mis-reading and not watching the video, the current method of plasma holograms or whatever will kill you, but the method proposed in the video is perfectly safe.
Not sure what I want to see first, the tech getting smaller or the hologram space getting larger, because 3D checkboxes would hold me off on the future shit for a very long time. Like imagine ordering something off a machine and it prompts you with holographic checkboxes to tap. You'd lose your freaking mind.
There is usually some truth which makes this too good to be true, what is it?

So I'm assuming the duty cycle of the laser-induced plasma image is low enough to prevent skin damage unlike previous tests? I wonder how well this would work in a noble gas environment...

Does "tangible interaction" mean you can feel it?

Ok. Now give us Holorifles already!
