  1. ReMarkable Texts Loring Holden Brown University April 20, 2004

  2. Goals (1/2) • Provide student app for ConferenceXP to complement Presenter • Create research platform for note taking • hard to extend existing note taking applications • our attempted remedy • BSD Open Source license • Plug-in architecture

  3. Goals (2/2) • Forge novel application • Aggregate functionality previously available only in separate apps • Formative evaluation in an academic (and possibly DoD training) setting

  4. Summary • What is different? • Gestural UI • Collaboration • Archiving and history playback • Interoperates w/ rest of Conference XP • BSD open source license

  5. Collaboration Implementation • N-way synchronous document & annotation sharing • Scalability • Uses ConferenceXP for multicast • Classroom variant has only one sender, so better scalability • Symmetric: Any participant can exit and rejoin easily • Collaboration metadata incorporated into document

  6. Collaboration metadata provides • Control over your own notes • Privacy • ACL's (who can modify?) • Mining • Author ID integrated into the system • Filter by user • Querying, for example: • What user wrote a particular stroke? (querying stroke for user info) • Which strokes were written by a particular user? (filtering by user) • When did who write what? (filtering by time)

  7. Collaborative note taking – future work • Easier collaboration startup • Easily fall back to asynch. collaboration when user not available • Figure out how each person’s doc looked at a specific time (people may have added ink at the same time, but the other person’s ink didn’t get imported until later) • Also show other docs open at the same time

  8. Sponsors and Availability • Co-funded by: • Microsoft Research, Microsoft TabletPC • NSF National Science Digital Library program • DoD Joint Advanced Distributed Learning Co-Lab • Publicly available: • http://ReMarkableTexts.org
