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 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).

Same issue, browser and hardware here. This is the error I see in my js console:

Uncaught Error: INDEX_SIZE_ERR: DOM Exception 1

Awesome idea and use of getUserMedia though.

Same problem here.

For a demo like this where failures can be caused by user error instead of app error, you should consider overlaying a tiny rectangle on screen that shows the webcam captured frames with an overlay of the recognition, so it's easier to tell if it's user error.

I took evanc's pull request (http://github.com/iambrandonn/WebcamSwiper/pull/3) and hosted it here for a quick demo: http://sumukh.me/labs/webcamswipe/

edit: It looks like the OP merged it back at the submitted url.

Worked for me after a refresh. A little buggy, but very cool. Imagine putting this on audio/video playlists for a simple skip feature.

REALLY glad to see this worked for some people, I was hoping it wasn't totally a bust!
