issues for information explosion in the communication network
Issues for Information Explosion in the Communication Network
  • ABUNDANT resources:
    • Bandwidth (Bandwidth blowout by photonics and next generation mobile)
    • CPU Power (Silicon progress, Moore’s law)
  • SCARCE resource:
    • User’s Time (Difficulty of finding right information)
          • (George Gilder)
      • Key for the user-friendly communication

Virtually Integrated Database

Direct access to databases

Brokerage by a facilitator

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

approach of chocoa
Product 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
