Question: How can I log viewer clicks on internet-hosted video?

I want to put a bunch of short videos on a website, and set it up in such a way that I can get a log of when viewers click the keyboard or mouse in response to what they see on the video. In other words, I want to tell the viewer, "Watch video A and click every time you see a cat." "Now, watch video B and click every time you see a dog." How might I accomplish this?

This is for art, not science, so accuracy only needs to be within 1-5 seconds.

On my end, the data I want would be a log of the click points for each video, marked as to which viewer was associated with which clicks. I want to later enter the data in a spreadsheet in a few different ways (e.g. to discover that 62% of all viewers clicked video A at point X; or that 90% of Russian-speaking viewers clicked video B at point Y).

That sounds like it would be easiest to modify an existing Flash video player. Maybe start with this one: Flowplayer, an open-source FLV player, and add buttons to do various things. (In addition to the usual play/pause/volume etc buttons.)

Since you need to get the time signatures of the clicks from the video, you definitely need some framework that encapsulates the video and the interface/counting code at the same time. You can't have buttons/controls underneath a simply-embedded video, for example, because you'll never get them accurately in sync: the control code won't know the video's position or state.

A Flash player like aeschenkarnos suggests is a good option if you don't mind Flash requirements/overhead. You can also embed clicks and code in QuickTime movies (there's an entire SDK for it, in fact) but it's not done often and I don't know any good examples offhand. I'd love some good textbook examples myself, as I've wanted to do some 'fun' projects that way in the past.

Note that if you use Flash or Quicktime (or any other method of embedding a video in a web page, AFAIK), it will only register if the user clicks on the video, not elsewhere on the web page
