Glasses-Free 3d Using Webcam Head Tracking

First thing, there is no loading indicator and it takes too long to start so I though it was broken a few times before I realized I had to wait longer.

Second thing, although it was clearly tracking my head and moving the camera it did not make me feel like I'm looking into a window into a 3d scene behind the monitor.

These kinds of demos have been around before. I don't know why some work better than others.

some others:

I'd say I'm not the only one who misses this technology in games, because a used New 3DS XL costs at least $200 on eBay right now, which is more than what I paid new.

I always thought 3D would combine really nicely with a ray traced graphics full of bright colors and reflections, similar to all those ray tracing demos with dozens of glossy marbles.

Systems like trackir, which require dedicated hardware.

8yo me, who instinctively tried to look behind the display's field of view during intense gaming sessions, would appreciate this feature very much. My belief is that if it shifted the pov to a lesser degree than in the demo, people generally wouldn't notice, but still subconsciously register this as a more immersive experience.

I'm also glad that the web version doesn't try to cook my laptop - good work.

I can see this quite useful for educational demonstrations of physics situations and mechanical systems (complex gearing, etc.). Also maybe for product simulations/demonstrations in the design phase — take output from CAD files and make a nice little 3D demo.

Maybe have an "inertia(?)" setting that makes it keep turning when you move far enough off center, as if you were continuing to walk around it.

The single-viewer limitation seems obvious and fundamental, and maybe a bit problematic for the above use cases, such as when showing something to a small group of people. One key may be to take steps to ensure it robustly locks onto and follows only one face/set of eyes. It would be jarring to have it locking onto different faces as conditions or positions subtly change.

We had as many people come test as we could, and we found that 90% of them didn’t get a sense of depth, likely because it lacked stereo-vision cues. It only worked for folks with some form of monocular vision, incl myself, who were used to relying primarily on other cues like parallax.

I think the problem is in real life you have an enormous number of other visual cues that tell you that you're not really seeing something 3D - focus, stereoscopy (not for me though sadly), the fact that you know you're looking at the screen, inevitable lag from cameras, etc.

I can't view the videos because of their stupid cookie screen, but I wouldn't be too excited about this. The camera lag especially probably impossible to solve.

I just tried this demo and it is cool, but nowhere as good.

One of the big issues with that phone was that in order to do dynamic perspective, you're having to run a 3D render at 60fps constantly. That's a huge power hog, and prevents you from doing many of the power savings techniques you otherwise could on a normal phone -- shutting down the GPU, reduced refresh rate, heck, even RAM backed displays.

Would you be able to clarify?

But you're still behind the window.
