Kudos to the Cooper folks for presenting thier Commuter Buddy “Drawing Board”. What a great example of a very quick slide/cast (basically).
The use of whiteboard wireframe images with quick shot photography (some even repeated) and then drawn on for UI’less design, was just brilliant.
What I particularly like about it is the way it uses a situated narrative with a well defined character (Ah! persona). This aspect of both character development and narrative is an important means of expressing design concepts that is often under utilized.
Another less rich mechanism for doing this is through comic storyboards.
