Question: how could this be exploited to provide unknowing access to a webcams via modifying this .js to run on a subjectively trusted page? Forgive me if I am being naive but just curious if this could be turned into something that accesses my webcam nefariously? Anyone on HN willing to test if this is possible?

Well, it's opt-in. So unknowing access is (at least without further actions) not possible.

getUserMedia: "Prompts the user for permission to use their Web cam or other video or audio input." [1]

By the way: The example doesn't work for me either.

Sure, but I am asking if this can be modded to gain unauth access to the webcam.

Possibly if someone managed to include it on a page you had already given permission.

I don't know if how you'd sent it somewhere with the same origin policy in place.

Cool idea! Demo didn't work for me on latest version of Chrome and a brand new MacBook Air though, and gave it a pretty good shot. I'm sure you didn't put this up without testing that it works, just didn't work after about 3-5 minutes of trying everything for me.

Didn't work for me either on MacBook Air and Chrome 22.0.1229.79.

Working for me on Air/Chrome 21.0.1180.89

Didn't work for me either (on chrome). I kinda felt like a moron waving my hands around trying to get it to work. Would have been cool if the camera was doing a live capture and would let me watch my moronic movements after a while.

This was exactly what I was thinking when it didn't work for me; the book page would finally turn and show all kinds of people doing swipes (in all possible ways) in the air... (Macbook Air 2011, latest Chrome).
