BTW, the OG demo from Johnny Lee is from 2007: https://www.youtube.com/watch?v=Jd3-eiid-Uw

Wow, thanks for sharing, that really takes me back. I was so hyped when I saw this as a kid, my dad and I made a mount for my glasses with two IR LEDs and a battery. I remember that I was super impressed with the effect.

After watching his videos, I went out and bought an IR pen so I could mimic his digital whiteboard. I think over the years, the bluetooth stack changed, so I could no longer pair with windows.

Good memories

this (and several of his ideas) were the reason I value simple solutions so much in my work along with optimising for low cost. "If Johnny Lee can do this crazy thing in cheap, I can think something creative too"

Samsung recently released a monitor with similar technology, I believe, as a FYI.

I'm surprised there's still a market for non-VR consumer 3D! I remember the post-Avatar rush of 3D-related products that never quite panned out.

I remember the 3D glasses that you could plug into the Sega Master System in the mid-80s. They took what would be interlaced frames and rendered them to different eyes instead (which made the version getting shown on the connected TV pretty trippy too).

And then there was the time travel arcade game (also by Sega) that used a kind of Pepper's Ghost effect to give the appearance of 3D without glasses. That was in the early 90s.

I think the idea of 3D displays keeps resurfacing because there's always a chance that the tech has caught up to people's dreams, and VR displays sure have brought the latency down a lot but even the lightest headsets are still pretty uncomfortable after extended use. Maybe in another few generations... but it will still feel limiting until we have holodeck-style environments IMO.

I got excited about this a few years ago when I was into digital pinball. I built an open source project called Phonemote using an iPhone to track eyes and relay telemetry over WiFi/BT and a plugin for FuturePinball.

However the result wasn’t that useful because we humans have 2 eyes.

The 3d effect is very compelling if you close/cover one eye.

But that becomes annoying quickly.

The best results I had was sneering a little hair gel in the center of my left eye glassses. Then it felt like I was using 2 eyes but really my right eye was seeing the pinball table clearly and fooling my brain.

There is a taiwanese company that has developed a sandwiched lenticular screen protector for phones that should fix this. Looks amazing in my opinion. You should try it out with your project.

Oh yes at the time I ordered a sheet but it didn’t align with my display panel. I should try that again.

Have you seen the video of the guy who built a camera to film light moving in super slowmo? The things people build amaze me.

Vr has taken over this market. Get a vr headset you won't be disappointed.

Other than DCS, Skyrim, and that one Star Wars game at Dave and Buster's where you duel Darth Vader, I don't see a lot that sings to me just yet. Granted, I could easily get 2,000 hours out of DCS over the span of a decade just flying every third and fourth generation fighter jet ever made. Maybe VR doesn't need that many games because the small handful of good ones have so much depth and replay value. I guess I just…

Not sure what vr kit you're looking at, but if it's a 4k headset to push at 90fps you'll want something more like a 3080 or 4070. But if it's lower resolution it won't need quite so much power.
