There's a professor in Biology here at Smith who has been using Lecture Capture technology. You can see his video speaking about his experience on YouTube (search Michael Baresi and Smith). I tried posting just the link here, but it didn't seem to work right. Hopefully the video isn't just something you can see from Smith.
I am a bit skeptical about using it. I was wondering if anyone out there is using it and, if so, what their experiences have been with it.
