Student annotated video of lectures

Today many universities are doing video of their lectures, and making it available on the campus LAN (or older campus cable TV.) In some cases students are not going to class, but many just find it a useful addition.

I suggest an application where students, while watching the lecture, could press keys on their computer synced in timestamp with the video. They don't need to be online, they just need a modestly good clock. Buttons like "This is important, review this for the final." Or even comments like "I already know this" and "I'm lost."

Students might use the timestamps themselves to build a "best of" video of the lectures, since you could not possibly watch all the lectures to review for the exam. The combined votes of students could be merged to produce a consensus vote on the best and worst parts of the lecture.

The professor could even review these things to see where the students are getting lost, what material they think is most valuable etc.

Of course this could also be done with plain audio of the classes but video would show the course materials and blackboards.

Perhaps one student in the class might take it upon herself to edit together a study video for others to use. They could even charge for it if it were really good.

Microsoft OneNote can do some of this

I've been using Microsoft OneNote on my X41 Tablet PC.

When you record audio at the same time as taking notes, the notes you take are indexed to that point in the audio. Apparently video works the same way.

Also, in the next version (http://blogs.msdn.com/chris_pratley/archive/2005/09/14/467123.aspx) the software will index audio so you can search for spoken words. It already searches your handwriting.

These features could surely be combined with a video feed so that your idea could be achieved.

I like OneNote. I use it more than any other MS Office product installed on my PC.

Check out Diver project

Have a look at http://diver.stanford.edu/. It does this and also allows you to crop to select video in space as well as time.

Thanks. That doesn't look

Thanks. That doesn't look like exactly the same thing but it's interesting. And ironic, because it was seeing the video lectures at Stanford which are delivered over the campus network (causing students to not bother attending some classes) which inspired me to think about this.

great idea

That is truly a great idea. Thanks
