Summary: The Presenter System for Tablet PC-Based Classroom Presentations

We describe Presenter, a presentation system that we designed, developed, deployed, and evaluated in
collaboration with Microsoft Research (available free at http://www.conferencexp.net/). Like traditional
computer and projector systems, Presenter uses a computer to drive a projector and display slides. However, the
instructor actually controls the presentation from a wireless Tablet PC (a mobile, pen-based computer).
Presenter combines advantages of conventional technologies such as overhead projectors, whiteboards, and
document cameras with advantages of traditional computer-based presentation systems. Presenter affords
handwriting and diagramming (as with conventional technologies); allows use of prepared material and easy,
real-time projection to remote sites (as with traditional computer­based systems); and by scrolling and scaling
writing and slides, Presenter can even simulate a much larger writing area than the tablet screen. The remainder
of this proposal describes the system in detail and summarizes classroom experiences and evaluation.
PRESENTER
In Presenter, the instructor loads a presentation composed of an ordered set of PowerPoint slides onto a Tablet
PC. Figure 1 shows the instructor's view on the tablet. She can write on the slides and control the presentation
using the tablet's pen. Presenter transmits writing and control information in real-time over an 802.11b wireless
network. In a distance class, remote sites would have their own displays, also controlled from the tablet via the
Internet. We used a prototype Acer TravelMate 100 Tablet PC and a modest Pentium II to drive the projector.
Assuming a classroom already has a computer and projector, Presenter costs about $2000 for the Tablet PC and
