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.
Do you have a link to that, sounds cool?
