Title: NotePals: Sharing and Synchronizing Handwritten Notes with Multimedia Documents


1
NotePals Sharing and Synchronizing Handwritten
Notes with Multimedia Documents
  • Prof. James A. Landay
  • January 14, 1999
  • BMRC Retreat

2
Observation
We often leave meetings without a shared
understanding about what occurred what was
important
3
Problem How to Create a Meeting Record?
  • Option A Private individual notes
  • Drawbacks
  • duplicated work
  • individuals may miss some points
  • miss others perspectives

4
Problem How to Create a Meeting Record?
  • Option B Appointed scribe records
  • Drawbacks
  • scribe is overworked cant participate
  • notes biased to scribes point of view

5
Problem How to Create a Meeting Record?
  • Option C Computerized meeting room
  • Drawbacks
  • expensive
  • cant have meetings anywhere, anytime
  • computers impede interaction

Shared Note Taking Exploration
  • Explored shared meeting notes with a 15 person
    research group
  • worked with them for 3 weekly meetings
  • Used small paper pads (simulate PDAs)
  • Had a volunteer help assemble notes into a shared
    record afterwards
  • Surveyed participants on different records
  • scribed minutes (their regular method)
  • handwritten assembled minutes
  • transcribed assembled minutes

8
Results of Exploration
  • Scribed notes do not contain more information
    than assembled notes
  • Users disliked handwritten notes since
  • hard to read fast
  • hard to search
  • -gt use off-line HWR for search/browsing
  • Users disliked lack of organization in assembled
    notes
  • liked assembled notes combined with scribed notes
    (using minutes for organization)
  • -gt use other documents to organize notes

9
Crystallized Vision
Take notes on PDAs/CrossPads synchronize after
the meeting with other documents!

How NotePals Works
Take free-form ink notes on Pilots or CrossPads
Meet in any environment
Pilots are becoming ubiquitous

How NotePals Works (cont.)
Dock Pilot/CrossPad with PCs Synchronize
Browse notes on the Web
14
NotePals User Interface
  • Problem Graffiti/HWR
  • Notes are free-form ink
  • Dont have to think about HWR
  • Single screen chunks w/o scrolling

16
Web-based Note Repository
  • Problem How to Share Use Notes
  • Merge all notes on web
  • Sort/Filter notes by
  • project
  • creator
  • date
  • stationery type
  • keyword

17
Web-based Note Repository (cont.)
  • Issue reading others HW
  • View notes at full size
  • Off-line HWR
  • keyword search
  • text for skimming

18
Web-based Note Repository (cont.)
  • Issue Follow-up
  • Respond online

19
Web-based Note Repository (cont.)
  • Issue organization
  • Use other media to organize (conference papers)

20
Web-based Note Repository (cont.)
  • Issue organization
  • Use other media to organize (presentation slides)

21
NotePals for Classroom Note Taking
  • Students always want slides in advance
  • often not practical or advisable
  • NotePals solution
  • synchronize notes w/ presentation (slides or A/v)
  • students can browse their own notes w/ slides
  • students can share notes cooperate

22
Classroom Note Taking
  • Issue organization
  • Use other media to organize (lecture slides)

23
Classroom Note Taking Experience
  • Decided to try with CS160 during Fall 98
  • course on UI design, prototyping, evaluation
  • All 50 students were given IBM WorkPads for the
    semester
  • all course projects also used these devices
  • Expected success
  • NotePals successfully used by our group for 1
    year
  • over 3000 pages of notes in our repository
  • successfully used by 3 students in grad OS course
  • at start of semester 89 of students said they
    took notes in class (72 shared)

24
Results of this Experiment
  • After 4 weeks of the course
  • only 48 reported taking notes
  • all said because slides were online complete
  • Of those still taking notes
  • only 33 using NotePals, others reported
  • screen too small
  • application too slow
  • paper more natural
  • UI hard to learn

25
Solutions Future Directions
  • Adopt NotePals II or TeamNotes UI
  • both eliminate gesture for moving cursor
  • use time/space to automatically shrink text _at_
    cursor

26
Solutions Future Directions
  • NotePals II or TeamNotes UI
  • both eliminate gesture for moving cursor
  • Create a better slide/note browser
  • early prototype was just that
  • CrossPad client
  • more natural for note taking
  • lots of success since prototype came up in Nov.
  • has resulted in many more notes in the repository
  • would like to obtain pads for an entire class
  • Re-run the experiment in a class that is less
    dependent on detailed lecture slides

27
Advantages of our Approach
  • Lightweight infrastructure
  • no expensive hardware or special rooms
  • Lightweight process
  • supports any style of meeting
  • Lightweight interface
  • free-form ink lets users focus on meeting
  • Lightweight sharing
  • share load of record keeping
  • not limited to a single perspective

28
Current Work
  • Better web organization filtering
  • improving HWR exploring other org. schemes
  • More user testing feedback
  • how does sharing change note taking?
  • New platforms
  • Improving CrossPad, Clio, Palm-size PC, etc.
  • Synchronization w/ presentation audio/video
  • May be most useful in non-meeting domains
  • small group notes
  • conference notes presentation slides

Sharing notes with NotePals can help groups
collaborate more easily
