– Integrate With High-end Visualization Environments
– ActiveMural, Powerwall, CAVE Family, Workbenches
• Build on Integrated Grid Services Architecture
– Develop New Tools Specifically Support Group Collaboration

• Physical Groupwork spaces
– lighting, audio, video, screens
• Virtual collaborative spaces
– strong metaphors for resource organization
– interaction scope management
• Agenda driven scenarios and work sessions

• Integration with GRID services
– resource management, security, services, brokering
• Debut at Chautauqua ‘99 in August and Sept.
– Boston U, U Kentucky, and UNM
– ACCESS, Argonne, NCSA, EVL, Utah (supporting sites)

The Access Grid: The infrastructure and software technologies enabling linking together distributed Active(Work)Spaces to support highly distributed collaborations in science, engineering and education, integrated with and providing seamless access to the resources of the National Technology Grid.
Access Grid Node: The ensemble of systems and services managed and scheduled as a coherent unit (i.e. basic component of a virtual venue).
Access Grid Site: A physical site (admin domain, networking POP, etc.) that supports one or more Access Grid Nodes. Access Grid Sites need to be Grid services enabled (authentication, QoS, security, resource management, etc.)

Projectors
• Features to look for
– LCD
– small, light, bright (1000+ lumens)
– Uniformity
– Low cost - $ 3,500 - $5000
– focus from 3.5’ to 38’
– screen size from 24” to 300”
– Quiet – fans can be noisy
• Some we use
– Proxima 9250, 9250+
– Epson 710c, 7500c
• Projector Mounts
– Allow easy alignment
– Sturdy

•
Windows 2000 Software
– AG Virtual Venue Software
Installation
– Microsoft Office 2000
•
Windows 98

•
VNC

• Structure and organization supports intended use
– activity dependent
• secure channels for “private sessions”
• broadcast channels for public meetings
• Supports multiple interaction types (modalities)
– text, audio, video, graphics, animation, VR
• Can exploit strong spatial metaphor
– interaction scoping
– resource organization
– navigation and discovery
• Needed to escape the tyranny of the desktop

• An often-overlooked aspect of meetings is side-band communications
(People whisper to each other)
• How can we enable separate channels of communications between meeting attendees at different sites?
• Text chat room as part of the virtual meeting room
• Persistent
• Capable of storing objects
• Searchable
• Recordable
• Client-server based

Globus Tutorial
Grant Writing Workshop
The Utah Engineering Experiment Station (UEES) at the University of Utah would like to have a reminder notice regarding the upcoming virtual workshop “Writing Winning Proposals” to be sent to all Access Grid members. The workshop is scheduled for May 10-11 in the Windmer virtual room. The workshop is cosponsored by the U.S. Department of Energy and is open to all individuals interested in improving overall grant writing abilities. I would appreciate, if your organization could send a reminder notice to all Access
Grid members regarding the workshop
