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
