2 One Motivating Factor Hoarding Erasers, Fall 2003 –From: Alicia Howe Sent: Wednesday, September 24, :57 AM Subject: Erasers in classrooms! We have just been informed by facilities that instructors are responsible for bringing erasers with them to their classrooms. If you bring an eraser with you to class, please remember to take it with you when you leave. The department just bought some small erasers yesterday and we are ordering some of the big ones today. We have 1 big one and 5 small ones in the supply cabinet. Thanks!

3 Overview Describe what a Tablet PC is, current technology Tablet PC features in Office How Tablet PC’s are being used in education –Lecturing –Collaboration –Discipline-specific applications Other academic and general-purpose uses –Note-taking –Grading and reading documents –Creating figures and diagrams –Brainstorming

4 What is a Tablet PC? Notebook running Windows XP Tablet Edition –Revival of pen-based computing idea; finally got it right? –Built-in support for Ink Draw with stylus, active digitizer Handwriting recognition Also support for speech recognition –Unlike a PDA, the Tablet PC runs everything on a normal Windows XP machine Form Factors –Slate –Convertible Currently entering second generation of devices –All with built-in wireless capabilities –Lonestar in Q2 of 2004

5 Sample of Current Tablet PC Technology 10” to 14” screen, mostly 1024x768 Mostly Ghz Pentium M $300+ more than non-tablet notebook HP TC1100 P-M, 1Ghz, 512 MB, 40 Gb, 10.4” XGA 3-4 lbs, detachable keyboard Fujitsu T3010 P-M, 1.4Ghz, 512 MB, 60 Gb, 12” XGA 4 lbs Electrovaya SC2010 P-M, 1.2Ghz, 512 MB, 60 Gb, 12” XGA 3-4 lbs, detachable keyboard 9 hour battery life Toshiba Portege M200 P-M, 1.5Ghz, 512 MB, 40 Gb, 12” SXGA (1400x1050) 4.6 lbs Gateway M Ghz, 60 Gb, 512 MB, 14” XGA 6 lbs, DVD

6 Entering Data Stylus serves as a mouse Ink - when application supports it Text Input Panel (TIP) when application does not support ink –Handwriting recognition –Speech recognition

7 Office Apps Microsoft Office XP (with extensions) and 2003 enabled for ink Outlook –Handwrite messages Word & Adobe Acrobat –Annotate documents with ink PowerPoint –Annotate presentation, content creation OneNote & Journal –Note-taking application tailored for the Tablet PC

8 Educational Use? How are instructors using Tablet PC’s today? Many are using tablets with a projector & Journal or OneNote to replace the traditional whiteboard/blackboard Benefits –Supports real-time writing; everything does not need to be done in advance, as in PowerPoint Some material difficult to do in PowerPoint (e.g. equations, Chinese) Material can still be prepared in advance –Can archive lecture content, don’t need tablet PC to view –Face toward class instead of toward the board –No messy chalk, markers, or erasers needed Can return to material that would be erased on a board But do need a projector

9 Tablet-Enabled Lectures Example: –Dr. Rafael Lopez-Mobilia’s lecture notes in Physics from UTSA

10 Tablet-Based Lecture Nice, but sometimes the final static lecture file is not enough –Can be unintelligible without real-time information, audio –My CS A201 lecture

11 Screen Capture One solution is to capture the screen and audio into a movie file –I used Camtasia Studio to capture the screen, audio, and convert the resulting movie into Flash format –Viewable on all modern browsers Disadvantages –Large file size; about 20Mb for one hour at 1024x768 Can trade-off with lossy encoding schemes, e.g. Windows Media Encoder –Built-in microphones generally of poor quality –Must remember to provide all gestures, interactions, on screen –As an example, this presentation will be captured and made available at

12 Classroom Presenter System developed at the University of Washington Components –Instructor uses Tablet PC wirelessly to communicate with server –Server hooked up to projector –Students also have Tablet PC’s to view and annotate instructor’s slide

13 Collaboration Possibilities If all students in the class have Tablet PC’s then interesting collaboration opportunities are possible with the wireless networking –Classroom Presenter Students submit answers to questions, instructor can select submissions to display to the class –Collaboration via Synchronous Course Management System E.g. Shared Whiteboard in Blackboard Possible over distance with systems such as Centra or Elluminate that share audio as well as whiteboard/slide content –Groove Workspace Shared files, instant messaging, project management, Office integration

14 Other Classroom Uses Real-Time Grading? –Could feasibly complete exams on the computer (both multiple choice and essay) and upload to instructor Brainstorming and Design Note Sharing –Various applications developed Instructor feedback? –Could provide instant feedback to gauge audience’s comprehension Distance Education? –Possibilities for distance education, can share data across a network with tools such as Media Encoder or NetMeeting

15 Discipline-Specific Applications Tablet PC applications for specific disciplines are just emerging Mathematics –xThink calculator –Upcoming Math Journal product Physics –MagicPaper

16 Art Pen is pressure-sensitive on most models Alias Sketchbook Pro

17 Music Composition Tool, Brown University

18 Software Development Tablet UML – Unified Modeling Language –Graphical language used to specify the requirements and design of software systems

19 GIS & Mapping GIS and Mapping Ruggedized Tablet PC for Military uses

20 Health Care Tablet PC’s increasingly popular among physicians Access to EMR (Electronic Medical Records) over the Tablet and wireless LAN –View, update chart, digital images, write Rx, send to billing all while with the patient –“Replacement of handwritten charts and scattered medical files with a unified system of computer records.”

21 Applications for Children Lots of child-oriented applications –Math –Art, painting –Learning to write in cursive

22 Uses Outside the Classroom Preparing figures and diagrams –Often easier to draw with the pen than a mouse Grading papers –If submitted electronically, can mark-up with the Tablet and avoid a big stack of papers eBooks –Easier reading of electronic books, magazines Web –New applications such as TabletBlogger, incorporate ink with blog Instant Messaging –Communicate with students or colleagues in ink with MSN Messenger

23 General Applications Planning, Contacts, Calendaring –Franklin Covey TabletPlanner –Organize handwritten or electronic notes, tasks, calendar, contacts, Word, Powerpoint, etc. Microsoft OneNote –Tool to organize handwritten notes –Less intrusive than typing in meetings or conferences –Store meeting notes in one place instead of on paper in file folders everywhere –Notes are searchable

24 Sounds Great, But… Some disadvantages of Tablet Technology –Keyboards mostly small –Screen resolution limited on most models to 1024x768 –Software applications limited, but growing –Handwriting recognition average –Clicking a little tricky –More expensive –Requires projector in classroom, may have difficulty using, setting up, smaller writing area than large black/whiteboard –Learning curve, around four days –Most require external CD-ROM –Display viewing angles often poor

25 Summary of Benefits Many benefits of Tablet PC technology for educators and administrators –Digital Ink more powerful than a blackboard Don’t need erasers, pens, or chalk –Collaboration possible –Some content more easily created –Content can be archived and broadcast –Discipline-specific tools emerging (e.g. Math Journal) –General tools already available (e.g. Outlook) –Tablet PC just as capable as any notebook, plus more
