Observing a demonstration
Modes of collaboration
• Videoconference
• Sharing data and objects
• Immersion in data or environment
Videoconference H.323 - multiple sites
Multiple HD streams
Access Grid -multiple streams from multiple sites
From Univ. of Michigan, Ann Arbor
AccessGrid.org
• Metaphor of “rooms” with meeting schedules
• Uses– VIC– RAT
• Multicast
Access Grid
• Good video of people
• No sense of space
The impact of metaphor
“Immersive telepresence”
Two classrooms - linked
Linking multiple cities
Change the abstraction from conference to other venue
Surgery
Bandwidth
Cisco
Sharing data in real time
• Document, whiteboard, image
• Powerpoint slide
• Shared application
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
Share an application - Powerpoint
Some data types can be shared
Your slide transmitted as an image
Downloaded slides controlled by speaker
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
Sharing an application -California and Australia doing simulated surgery
Internet 2
Collaboration architecture
Image library and 3D models
Displayserveron the Net
Client Client Client Client
Image is pushed to any client who logs on
All clients have cursor control of tools
From screen viewing of data to immersion in the data
Virtual world
Group is instantiated instead of abstract
Virtual Emergency Room
• User accesses “behaviors” through menu• Patient physiology is small set of rules• Interactive scenario is followed by debrief
Virtual emergency team
Collaboration with large display
Virtual Hospital
