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

• 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

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
