  1. Pervasive Pixels Henning Schulzrinne (PI) Steven K. Feiner Gail Kaiser John Kender Kathleen McKeown Department of Computer Science Columbia University

  2. Proposed Research Goal: seamless mobile multimedia collaboration across distance • Integrate advances across fields • Collaborative work • Graphical and visual interfaces • Spoken language understanding and generation • Vision sensing and understanding • Networking and security

  3. Contributions • Contextual information management • use workflow to determine display content • multimedia summaries of past and present sessions • Harmonizing physical and virtual environments • map changing virtual information onto physical displays • map layout of physical environment onto virtual space • Network services • clear, flexible interface to common services • authentication and privacy support • operating system infrastructure for large displays

  4. Features of Research Infrastructure • Large, instrumented multi-display workspaces • Networked mobile devices of various capabilities • Transparent and automatic adaptability to changes of place, platform or group • Support for a wide range of hardware and software, from commercial to novel

  10. The Department of Computer Science • A growing faculty • 5 new assistant professors (pictures and areas here) • 1 new full professor: Peter Belhumeur • 1 new full professor 9/02: Julia Hirschberg • A large student population • 80 PhDs • 155 MS • 380 undergraduate majors • Internal, fluid collaboration • Interdisciplinary connections

  11. Building Critical Mass • Networking • Schulzrinne, Misra, Yemini • links to EE • Vision • Allen, Belhumeur, Kender, Nayar • links to computer graphics • Human Computer Interaction • graphical and visual user interfaces: Feiner, Kender • spoken and written language: Hirschberg, McKeown • links to speech and multimedia in EE

  12. Areas of Growth • Security and systems • Computer engineering • Computer graphics • Theory • Sofware systems (e.g., programming languages)

  13. Administrative Support • Institutional cost share on this proposal: $1 million in total • $100,000/year for 5 years (Provost) • $100,000/year for 5 years (Dean) • Support for growth: slots, space • Financial support • return in revenue (e.g., Columbia Video Network) • Technical transfer support • dedication of Columbia Innovative Enterprise services

  14. Current Departmental Facilities • Shared infrastructure of over 20 Sun and Pentium servers • Two teaching laboratories • 40 seat student lab (CLIC) of Intel Pentium PCs, dual projection capability, wireless microphone, video mixer and multiple cameras • 30 seat Microsoft Research Lab • Nortel Meridian telephone switch • Research infrastructure of > 500 nodes plus servers • Staffed by 4 professional system administrators

  15. Research Infrastructure • User-based personalization: user location • magnetic card readers • active badge system • triangulation on mobile devices • visual tracking • Stationary setups • Seminar room • 3 meeting rooms • 12 faculty offices • 5 public areas • portable units

  16. Seminar room • High-resolution DV video camera, 2 pan-tilt speaker cameras, Omnicam omnidrectional audience camera, video switcher, 16 ceiling mounted microphones, electronic whiteboard, 3 XGA high-brightness video projectors

  17. Meeting Room • 2 remote-controlled pan-tilt video cameras, Omnicam, conference table PZM boundary microphones, automatic audio mixer, ceiling speakers, 3 high-lumen XGA video projectors

  18. Faculty Office • Mimio electronic whiteboard, XGA video projector, Ethernet speaker phone, wal-mounted pan-tilt video camera, PocketPCs

  19. Public areas • Walk-by stations and laboratories • XGA video projector, steerable ceiling-mounted dome video camera, embedded ceiling mounted netowrked Pentium computer, celing speaker, Andrea DA-400 array microphone, Microtouch IBID 600 whiteboard. • Picture here

  20. Design for walk-by collaboration • Figure 1 here

  21. Functionalities • Conferencing • Internet conferencing server to mis IP and PSTN audio streams • Interconnection with analog phone • Digital hybrid connects digital or analog sound to existing telephone system in classroom • Netowrk voice-over-IP interface attached to Nortel Meridian PBX for 20 simultaneous conversations • Multi-processor servers and IA64 compute and database server, plus others • File storage • Face, speaker and fingerprint recognition • 2 printers and tape library system in year 4 for backup

  22. Remaining Agenda • Research Overview • Contextualized Information Management (Kaiser) • Harmonizing Physical and Virtual (Feiner) • Network Services (Schulzrinne) • Genomics testbed (Noble) • Responding to reviews (Kender) • Telephony demo (Schulzrinne) • Lunch • Demos • Visit with administrators • Demos • Small group meetings
