  1. Collaboration and Grid Technologies Parvati Dev, PhD Director, SUMMIT Stanford University School of Medicine

  2. Physicians do not work alone From Fotosearch and Web

  3. The Operating Room

  4. People around a table

  5. Observing a demonstration

  6. Modes of collaboration • Videoconference • Sharing data and objects • Immersion in data or environment

  7. Videoconference H.323 - multiple sites

  8. Multiple HD streams

  9. Access Grid -multiple streams from multiple sites From Univ. of Michigan, Ann Arbor

  10. AccessGrid.org • Metaphor of “rooms” with meeting schedules • Uses • VIC • RAT • Multicast

  11. Access Grid • Good video of people • No sense of space

  12. The impact of metaphor

  13. “Immersive telepresence”

  14. Two classrooms - linked

  15. Linking multiple cities

  16. Change the abstraction from conference to other venue

  17. Surgery

  18. Bandwidth Cisco

  19. Sharing data in real time • Document, whiteboard, image • Powerpoint slide • Shared application

  20. Document and object camera Allows you to grab content other than from your screen Object (skull) - show anything, not just paper Live experiment Usually allows screen capture to a jpeg image

  21. Share an application - Powerpoint Some data types can be shared Your slide transmitted as an image Downloaded slides controlled by speaker

  22. Share any application - VNC • Vnc supports a shared desktop • Anything on your screen can be seen by all others linked to your computer • Any person can control what is on your screen

  23. Sharing an application -California and Australia doing simulated surgery Internet 2

  24. Collaboration architecture Image library and 3D models Displayserver on the Net Image is pushed to any client who logs on All clients have cursor control of tools Client Client Client Client

  25. From screen viewing of data to immersion in the data Virtual world Group is instantiated instead of abstract

  26. Virtual Emergency Room • User accesses “behaviors” through menu • Patient physiology is small set of rules • Interactive scenario is followed by debrief

  27. Virtual emergency team

  28. Collaboration with large display

  29. Virtual Hospital
