What Agent Technology can Provide What Agent Technology can Provide
• Easy access to services by hiding differences of – Access network systems
– Server/database systems
• Adaptive selection of services– Geometry dependent information filtering
– Selection of available communication method
• User customized services

Direct access to databases
• Users must know where databases are, and how to access them.
• Users must access to each database by themselves.
Virtually Integrated DatabaseVirtually Integrated Database
• Users must know only a facilitator.
• The facilitator accesses databases on the user’s behalf in parallel.

Approach of CHOCOAApproach of CHOCOAProduct initiated by necessity
Advantage of large room
– Always possible to see each other (Awareness)
– Always possible to talk to each other
– Multi-person discussion is possible
Virtual large room (for researchers and engineers)
– Real-time and quasi real-time communication system
– Media : Multi-user and multi-party text chat system + Voice for compensation of text’s drawbacks
Technical background Telephone system: Circuit-switched --- Always-ON is expensive Internet system: Packet-switched --- Always-ON is possible
