2. Distributed, Tablet PC Application Initial development, 2001-2002 at MSR as a component of ConferenceXP Continuing development at UW Key scenarios Classroom Presentation Distance Learning Classroom Interaction Versions CP 2.0: 9/2003 CP 3.0: 1/2007 Classroom Presenter Instructor Note

3. Classroom, ink based presentation • Combine writing with prepared slides • Support the flexibility of spontaneous explanation • Target interactive presentations • Needs of the classroom are different from other forms of presentation

5. Classroom Presenter vs. PowerPoint • Although PowerPoint does include facilities for delivering a lecture from a Tablet PC, this has not been addressed as a core scenario • Many instructors feel (quite strongly) that CP offers significant add advantages • What are they . . .

6. 10. Default inking • Writing on slides is enabled by default – there is no mode switch necessary to start writing

7. 9. Multideck model • The filmstrip supports multiple slide decks. • For presentation, the most common use is to be able to move between a collection of whiteboards, and the prepared slides

8. 8. Full screen erase • A single button removes all ink. • Much easier and faster than erasing individual strokes • Erasing is a tremendous challenge when using ink in presentation • Errors in erasing are common • Scratching out is a common alternative • Open area of research to improve ink erase functionality while presenting

9. 7. Distributed Presentation • Presenter is designed as a distributed application, so a synchronized copy can run on a second machine • This allows a second machine to drive the projector, so that the instructor can use an untethered tablet

10. 6. Extra writing space • Two mechanisms are provided for writing space • Shrinking a slide to give a border area for drawing • An extensible whiteboard deck

11. 5. Lecture export to HTML • A single click exports the slides with writing to html allowing slides with ink to be posted to the web • There is room for improvement – but this simple way to summarize lectures in considerable valuable by students and instructors

12. 4. Slide previews • Slides in the filmstrip can be previewed before they are shown by using the stylus • A large number of slides can be present on the film strip and it is still possible to look at slides before they are displayed

13. Film strip navigation • Tapping on a slide on the film strip advances to that slide • This facilitates non-linear access of slides and moving back and forth

14. 2. Instructor Notes • Content can be marked instructor only, so it is only visible to the instructor, and not displayed to the students • This allows notes to be embedded on the slides • Some instructors make very significant use of this

15. 1. Simple pen based UI • A small number of buttons are available in the instructor view for changing pen options and navigation • Designed for pen use – e.g., extra large buttons • Presentation UI necessary for efficient pen based operation

17. Why PowerPoint is better then Presenter • Out of fairness, there are significant advantages of PPT over CP • Animations • Incorporation of Multimedia – video and sound • For formal presentations, PPT may be more appropriate
