Snowed In

I gave a presentation about my progress on my second year project in our lab meeting today. Mostly what I’ve achieved since last quarter is building the application you see pictured above. The data I’m collecting is several video streams of people interacting with a computer. The trouble is, I really need to be able to watch it all at once, to see how peoples gestures interact with each other and with the screen, and with what’s happening in the computer.

A had a hunch that this would be pretty easy to do on a Mac using the Cocoa and Quicktime APIs. The trouble is, I don’t know Mac programming, or the Cocoa or Quicktime APIs, nor do I know Objective-C, the language of choice on Macs.

But, what the heck, I thought. I’ll give it a try.

And I did! And after a week of head scratching punctuated with moments of triumph and brief periods of mild depression I have this gem of an application.

Now to do the actual analysis…
