When I was a student, standardization work was considered very
important in a research community. However, internet has changed the
way of standardization. Good things propagate very quickly and
becomes de-facto standard. Standardization procedure has changed.

3D graphics interactive textbook.
3D graphics will play an important role in future internet
application. It suits well for educational purposes.
A textbook for high school students to teach about human body. In the
demonstration, first the 2D illustrations of parts of human body is
shown on the Netscape. When a student select a picture, its 3D
representation is popped up in a different browser. You can change
viewpoint or do some live simulation.

Current status of high speed communication in home computing in
the U.S.
ISDN has virtually failed in the US, because of high cost, and little
promotion by telecommunication companies.
xDSL gives symmetric and asymmetric high speed data communication
channel on existing copper line. Asymmetric xDSL is suitable for
broadcast type data communication. xDSL can provide a transmission
rate of 6 Mbps, enough to transmit HDTV quality motion picture
data. High speed access to the internet with low cost. It is an
important factor, and whether the providers can offer exciting offers
to attract the customers is another.
There will be 2 satellite based service available by the end of this
year. There are 2 DBS (Direct Broadcast Satellite) in the U.S. and
they may change how we view multicast by Microsoft and Echostar.
Today's computer network is so unreliable. It must not be the toys for
researchers anymore. To avoid panic, a plan with sutaineable computing
is needed. There can be no more inconvenience. a little inconvenience
can cost millions. We need to have a service criteria other than
bandwidth.
Andy Hopper (Univ. of Cambridge)
Centralized and ubiquitous computing.
How would you feel about a personalized global communication service
that followed you around the world.
Computer communication is almost unusable. It is too difficult to
learn, to complicated to be used for majority of potential users. We
are in a hopeless mess and how can we deal with it?
Out answer is to return to centralization and sustainability.
Using simple, stateless endpoint terminal which can be reset at any time.
Information is stored in the server and you can download it from anywhere in
the world.
The goal
- ubiquitous personalization
- "I did it my way"
Ted Nelson (Keio Univ.)
A correct architecture to handle information, Transcopyright
Present computer application has totally wrong architecture to handle
information. Engineers have developed applications with incorrect notion
of information structure. Writing is a simplicity of the true complication
of information system.
When people say Web is chaotic and the want order,
they are misunderstanding the structure of information. Information is
supposed to be chaotic, and people are misunderstanding. It is important to
be able to maintain a mass number of interconnection between information.
- OSMIC: a data structure for information
- Transcopyright: Give permission to republish the material
virtually, under the condition that only an address pointer to the
material is distributed by the republisher.
Traditional copyright limits people from distributing material,
but transcopyright is the opposite.
- Micropayment: A system to let people pay very small fee of using
copyrighted materials.
