03:41 < fenn> ah the accelerometer is for balancing, it displays vectors on the round LCD
03:51 < fenn> he could have just bent the display panel so that it's balanced and still doesn't block the central axis
03:59 < L29Ah> was planning to do a similar thing but rocking instead of rotating, to avoid unreliable sliding contacts or complicated wireless design, during adolescence
04:55 < fenn> the voxon cubical display twangs a rectangular screen up and down on springs
04:57 < fenn> square:cube :: rectangular:right parallelepiped
04:58 < fenn> getting a high enough refresh rate seems to be the trick
05:00 < hprmbridge> kanzure> are the television microLED arrays hackable for high refresh rate?
05:00 < hprmbridge> kanzure> probably lower refresh rate as sold but the actually addressable microLED array should be drivable?
05:01 < fenn> the higher resolution the display, the higher the refresh rate needs to be to provide similar inter-dot spacing
05:01 < fenn> in the z or theta direction
05:02 < fenn> i have no idea what goes into a TV these days, but you can buy 500Hz gaming monitors
05:02 < hprmbridge> kanzure> when does it flip to being memory / memory bandwidth limited for the buffering and preprocessing
05:03 < fenn> DLP projectors can be insanely high speed but you probably have to sign NDAs to get the protocol...
05:03 < fenn> it would be cool to spin a bunch of laser projectors around a fog bank to do inverse tomography
05:04 < fenn> then you could actually poke at the holograms, sorta
05:04 < fenn> plus standing wave ultrasound for haptics
05:05 < hprmbridge> kanzure> oh just use a fog machine?
05:06 < fenn> two photon induced fluorescence could get rid of the bloom
05:06 < fenn> well, some of it
05:08 < fenn> i had some idea about inkjet droplet as the display screen but it probably doesn't make sense
05:10 < fenn> all of these technologies suffer from the problem of always showing all faces, so you can only display transparent objects
05:10 < hprmbridge> kanzure> inkjet electrospray of particulate clouds, spin inside snow globe, vacuum or air flow for refresh rate. idk I'm sleep deprived.
05:12 < fenn> little known trick: when you charge up glow in the dark stuff with UV, you can "quench" it with an IR laser, releasing all of the light energy stored up
05:12 < hprmbridge> kanzure> inkjet is just shorthand for piezoelectric ultrasound ejection of a substance, similar to the ultrasound levitation gimmick
05:16 < fenn> so you could have a fog of phosphorescent liquid with UV and IR projectors at 90 degrees out of phase, the UV charges up a cone/prism of particles, and the IR quenches another cone/prism volume, and where they intersect you get light out at the right time. meanwhile the un-quenched slightly-glowing particles diffuse around and hopefully aren't too noticeable
05:18 < fenn> my inkjet idea was more like, shoot particles exactly where and when you want them to be, which introduces a small latency to the display
05:19 < fenn> then a laser projector illuminates each individual particle, and you interlace parabolic streams of particles to fill in all the gaps
05:20 < fenn> you wouldn't want to stick your hand in that, it would get wet
05:21 < hprmbridge> kanzure> moist holograms, gross
05:26 < fenn> it could also be a vat of liquid but that would be inconveniently heavy
05:27 < fenn> the phosphor idea
05:30 < L29Ah> anyway, i figured volumetric displays suck compared to HMD with position tracking
05:35 < fenn> yes but HMD doesn't work so well with multiple users
05:35 < fenn> with kalman filtering and fast pose estimation you don't even need the HMD
05:36 < fenn> face tracking
05:37 < fenn> i expected this to become a standard thing like 10 years ago with kinect, and then it didn't
05:37 < L29Ah> HMD works everywhere without clunky and fragile hardware
05:38 < fenn> uh heh okay, right
05:38 < fenn> HMD is totally not clunky or fragile at all
05:39 < fenn> they had the right idea in the 90s with CAVE: a projector and active shutter glasses for each viewpoint
05:40 < fenn> active shutter LCD glasses can run for days on a single CR2032
05:40 < fenn> battery
05:41 < fenn> multi-view displays are still not really a thing, i found one company selling them (no price listed but it looked big and angry)
05:43 < fenn> there's no reason you couldn't just use a high framerate monitor
05:44 < fenn> divide by the number of independent viewpoints to get the final framerate
05:45 < fenn> it still has the "vergence/accomodation conflict" due to focusing on the plane of the display instead of the virtual object
05:48 < fenn> magic leap seems to have given up on this quest despite dumping hundreds of millions into it
05:50 < fenn> "thousands of patents" they brag
05:50 < fenn> i've never seen one
05:59 < fenn> 3 hour battery can't be swapped. probably a bomb :)
06:02 < fenn> oh boy you can't even use it while plugged in
