In this 1.5 hour video, Bill Buxton talks about sketching and prototyping user interfaces.
To Bill Buxton, sketching is fundamental to ideation while prototyping is an evaluation technique. In ideation, the goal is to come up with many different ideas. In evaluation, you narrow down choices of ideas. Sketching is a way of "getting the right design" while prototyping is "getting the design right."
