4 1.1 Motivation Poor communication among members resulting in integration problem. Network resources require for costly and bandwidth capacities. Companies must learn to communicate and work in a collaborative design and development endeavor.

2003 NTHU IEEM Objectives Accelerate fulfillment, quicker delivery. Reduce product development time and costs. Resource sharing. Learning through trading partner network.

2003 NTHU IEEM 6 Systems must enable changes in product development and communicated to all parties involved in the project.

2003 NTHU IEEM 7 Multiple users at different locations can work on one design collaboratively and simultaneously. No travel and no delay. Higher Productivity, Lower cost, Better Traceablity.

2003 NTHU IEEM Research Domain There are many collaborative projects using the Internet and many partners who work together exchanging files and interacting on shared digital models. Collaborative activities are an important application of computer technology. Many software develop many tools to support such collaboration. But what are the implications for tools that support this work? Our project use Access Grid for design project as an example.

2003 NTHU IEEM 12 Collaboration Application What does it do? What does it do? Solves specific issues with project development and product design: early stages of product development can be 80% of product cost Information exchange Information visibility Information format Protocols Conflict resolution Allows more chances for revision and evaluating design options Allows people in multiple locations to identify and prioritize project work Technology Access (Web browser) Structured data transfer (input/output matching) Process collaboration (share through workflow)

2003 NTHU IEEM 15 Introduction & History The Access Grid was developed by the Futures Lab at the Argonne National Laboratory’s Math and Computer Sciences Division. They defined it this way: The Access Grid™ is an ensemble of resources including multimedia large-format displays, presentation and interactive environments, and interfaces to Grid middleware and to visualization environments. These resources are used to support group-to-group interactions across the Grid. For example, the Access Grid (AG) is used for large-scale distributed meetings, collaborative work sessions, seminars, lectures, tutorials, and training. The Access Grid thus differs from desktop-to- desktop tools that focus on individual communication. The requirements of the Access Grid project were: Group to group interaction Multiple Locations Comfortable environment

2003 NTHU IEEM 16 Focus of the Access Grid Project To enable groups of people to interact with Grid resources and to use the Grid technology to support group to group collaboration at a distance : Distributed research collaborations Distributed lectures and seminars Remote participation in design and development Virtual site visits and team meetings Complex distributed grid based applications Long term collaborative workflows

2003 NTHU IEEM 21 Group-to-Group Interaction is Different Large-scale scientific and technical collaborations often involve multiple teams working together “ Presence ” requires multiple views from each site, and a large-scale display Group-to-group interactions are more complex than individual-to-individual interactions The Access Grid project is aimed at exploring and supporting this more complex set of requirements and functions

2003 NTHU IEEM 22 The Access Grid: a collection of designed spaces enabling group to group interaction Hands free audio Multiple Video and Audio streams Wide field of view Virtual collaborative spaces Secure Rooms Integration with Grid services

2003 NTHU IEEM 23 Access Grid and Collaboration Technologies Connecting People and Applications via the Grid Access Grid  Integrating Group to Group Collaboration and Visualization

2003 NTHU IEEM 24 Access Grid – The Novel Ideas Peer-to-peer Virtual Venues servers to enable worldwide, secure virtual communities through the use of high-end collaboration environments Collaborative work sharing beyond simple application sharing Integration of high-end visualization environments into collaborative spaces Methods of asynchronous collaboration: capture, synchronization, recording, playback and annotation of collaborative experiences

2003 NTHU IEEM 25 Access Grid Goals Enable Group-to-Group Interaction and Collaboration Connecting People and Teams via the Grid Improve the User Experience: Go Beyond Teleconferencing Provide a Sense of Presence Support Natural Interaction Modalities Build on Integrated Grid Services Architecture Develop New Tools Specifically Support Group Collaboration

2003 NTHU IEEM 26 Access Grid vs. Commercial Desktop Tools AG targets beyond the desktop large format multi-screen for AG Global Channels room scale hands free full-duplex audio AG software is Open Source extends and builds on community tools AG environment is integrated with Grid services extensible framework designed to “ plug-into ” the Grid AG development is a Community Effort you are welcome to join in the fun!!

2003 NTHU IEEM 27 DEMO

2003 NTHU IEEM 28 Our Future Research Test various network connections, like ADSL, T1…, and solve connecting problems. Debug the AG program source code and try to develop some functions, like shared-presentation, electronic whiteboard or others. Modify AG and apply to collaborative workshop in the web server or others.
