6. Conclusions This work describes the Classroom Presenter lecture presentation system developed at the University of Washington. We highlight some of the specific utilities of the system in the context on an undergraduate computer architecture course. The main benefits of Presenter stem from wireless, high-quality inking over slides during lecture

Appendix: Classroom Presenter Feature List
The Filmstrip. The Filmstrip is a “preview strip” of slides
facilitates non-linear slide navigation order, allow faculty to react to the development of discussion in class.
Filmstrip preview. Another benefit of the filmstrip view is to allow the instructor to make appropriate concluding comments based on the content of the next slide to be displayed. Filmstrip preview makes this more viable by showing an instructor-visible “zoomed in” version of a filmstrip slide when the tablet pen is “waved” over a portion of the filmstrip.
The Toolbar. Back and forward buttons are placed at both ends to allow easy movement one slide in either direction of the current slide. Four inking colors are supported as well as two ink “tips”: a square and a round tip. The next three buttons select “regular pen” inking, highlighting, or stroke-
