Missed it :(

#13Why not a GoPro on a wheel? Edit: I just think I should've googled that first.
I would guess a GoPro doesn't allow Apps nor has the sensors accessible to perform the experiment with an external computer.
[edit] I do wonder why we haven't seen more programmable cameras with the sensors a smartphone has.

... Because this is an iOS app?

#15I have some serious sea legs and almost never get motion sickness. The fullscreen youtube vid got me. Great experiment.
I'm getting motion sickness just thinking about it. Haven't even watched yet.

Absolutely blown away with the demo video (centripetal issues aside) though annoyingly I'm one of those 'other' users, so I have to ask: Anything android related in the pipeline?

#17I poked around the website and their projects look awesome, exactly the kind of stuff I'd make if I were more talented. I wish I lived in Greece because I would find these guys and beg them to hire me.

#18I found this to be really incredible. That is some amazing video stabilization technology. If this app was available for android I think I would use it for every video capture I ever do.

#19Better title: "Show HN: We put an iPhone on the front wheel of a car and drove really slowly for less than 10 seconds at a time"
50 km/h is fast enough for this experiment if you ask me.

Because the focus of the experiment is an app that records videos while compensating for tilt/rotation (it's not just "hold muh beer while I tape my iPhone to a car wheel!"). I have the app, and find it interesting for its ability to eliminate the inevitable angling of the video, despite being on such an unstable mount (my free-waving hand). By subjecting the app to extreme conditions of rapid rotation, subtle flaws in the compensation process are made apparent - specifically, that the iPhone's gravity sensor gets confused & skewed, that the progressive scanning of each frame means distorting the image (the top of the image shows a view 1/60th or so of a second different from the bottom), and the two together result in a bizarre/unexpected periodic warping of the image. Having this video, the experimenters can go back to the software lab and tweak their image processing algorithms to compensate for these errors and create an even more stable image.
"So what?" you mumble. "It's so subtle nobody cares."
Well, that's actually a big part of why VR failed when it was first introduced a couple decades ago, and why Carmack & Occulus are so successful with it now: they've analyzed the subtle nuances that you don't acknowledge but your brain processes & reacts to nonetheless. Horizon is applying the same attention to detail, and will produce a better product as a result (yes, I do notice those sub-frame distortions in various products almost daily, and would appreciate developers correcting them).
