Cool fact, a Slovenian company that is now SF based has made this tech into an iPhone app a few months ago. -> http://www.azumio.com/apps/cardio-buddy-2/ I really like their apps and I'm quite proud that they originate from my neck of the woods.

It's a nicely designed app, but it doesn't work that well. Told me I had 60, 62, 61, 59... BPM when in fact it was over 75.

What in the world? Is this magic?

On each heartbeat, blood is pushed and makes the skin nearly unperceivably redder. By watching for and tracking this subtle change, you can extract a heartbeat.

But why is he analyzing the green channel then? :)

Give it a video feed from a political debate and live-tweet the politicians pulse on different topics. I foresee a future of politicians sporting bangs and bob cuts.

They're already so heavily made-up for the cameras I would be surprised if this worked.

The paper that this is based on is also pretty fascinating: Eulerian Video Magnification for Revealing Subtle Changes in the World http://people.csail.mit.edu/mrub/vidmag/

Patented :'(

Well, in my opinion, a patent like this is well deserved. I could be wrong, but the researchers have spent significant time on it and have discovered/invented something really unique.

that's the tragedy of it. something cool is invented and now it'll be fenced off and buried for 25 years in all likelihood, and/or becomes part of a big patent portfolio.

doesn't a patent imply that you must let other people use your idea in exchange of a fair price?
