trip report from the eighth World Wide Web conference
in toronto, canada
first day (wed 12-may-1999)
|
opening ceremony:
according to the list of attendees, there are about 700 pre-registered
people present at this conference.
welcome note:
robert cailliau said: 10 years ago, when tim berners lee proposed the World
Wide Web for the first time to his boss at CERN in geneva, the closing comment
was "vague but exciting".
key note speech by tim berners lee:
tim gave one of his very typical, enthusiastic but yet exciting talks. here
are some quotes that i picked up and that i found especially remarkable:
- access for all
- exploitation of computing power in real life
- machine understandable data
- a short history of the web:
- 1989 concept
- 1990 browser/server
- 1991 justification
- 1992 persuasion
- 1993 proliferation
- 1994 WWW1/2, W3C
- 1996/97 PNG, PICS a.s.o.
- anything can point to anything
- independent of everything
- minimalistic design
- human communication through shared knowledge
- goal: intercreative space
- needs some stability: slow down, get it right, reduce the number of invalid
documents
- the machinery of the web: well defined data documents are basis for
transactions (clean up the model !)
- expressive power: links of meaning form a web
- a web of thrust: a web of signed documents (W3C/IETF joint work on signed
XML & RDF starting)
- web of people: weaving ourselves into the web
- raising the level of ethics
- have fun, dream, code !
W3C track introduction:
jean-françois abramatic introduced the five sessions of the W3C that
we will see during this conference:
- World Wide Web access
- XML: from markup to meaning
- web technologies serving society
- multimedia models and management
- community contributions and participation
W3C web accessibility initiative & web content accessibility
guidelines:
WAI: accessibility of the web for people with disabilities.
barriers:
- web technologies
- web content
- browsers, authoring tools, related tools
- gaps of awareness of the need for accessibility
businesses may be unaware that they are missing this marketplace.
accessible design may help access with different devices including mobile
devices etc.
activities include:
- announced W3C recommendation may 5, 1999
- techniques document published as a note the same day
- accessibility guidance for graphical, text and voice browsers, multimedia
players, assistive applications as a public working draft
- accessibility guidance for WYSIWIG editors, conversion tools, dynamic
content generators, image editors and site management tools as public working
draft
- evaluation and repair tools
- education and outreach working group: increase awareness of need for
accessibility, promote implementation
web content accessibility guidelines V1.0:
- provide text equivalents for visuals
- make frames accessible
- use meaningful link text
- add structure (e.g. <Hn> instead of <B>)
- use style sheets
total of 14 guidelines, see WAI guidelines
W3C internationalization:
internationalization and universal access (accessibility) are related.
issues:
- client-side translation helpers (machine translation)
- confusing dates (02/03/04 could be march 2, 2004 or march 4, 2002 or
february 3, 2004)
- character encoding and language negotiation in HTTP V1.1
- allow cultural diversity, reduce technical diversity
W3C mobile devices
3 solutions to show web pages on mobiles:
- resize
- reformat
- reformulate
applications are different:
- not about surfing, it's getting information such as "when goes my
train ?"
- XML is the key
- first step: apply the WAI guidelines
"people should not think in pages, they should think in
objects !"
mobile device and accessibility panel
comparison between access to the web with mobile devices and people with
disabilities:
similarities:
- limited size of the display
- needs summarization
- needs linearization
- limited or no use of graphics
differences:
- people with visual disabilities adapt more easily to robotic voices and are
used to speed up speech
everybody agrees on that mobile devices benefit from improvements for
accessibility and vice a versa.
information should be provided consistently regardless of the device being
used. people accessing a particular website using a regular browser expect to
find the same information in the same place when they use a mobile device.
beside content and presentation, there is a third element: structure !
if the structure and the content are right, presentation will adapt gracefully
to any presentation.
additional suggested
reading
key note speaker john patrick, IBM
as on many WWW conferences before, john patrick gave one more of his very
interesting and entertaining speeches. again a few quotes that i found
especially remarkable:
- instant messaging: real-time communication with on-the-fly translation
- symbiotic video: tv clip where you can click on the product for detailed
information or to order it
- lego mindstorm: learn from a 7 years old kid
- 24x7 learning: web based education
- the bandwidth will grow. the cable companies compete with phone companies
which compete with companies providing Internet connectivity via satellite.
full screen video will be available over this extended bandwidth.
- geo-independence: medical experts can analyze a patient via the Internet
poster reception:
jakob lindenmeyer and i presented our poster about
measuring accessibility. we
consider this presentation very successful. we did not only display the poster,
but we also had a notebook with pwWebSpeak - a voice web browser - running and
two Windows CE systems on hand. we had a lot of people who were interested in
the subject, including representatives from the W3 consortium.

production note:
this trip report was written on a Vadem Clio
C-1000 running Windows CE with Pocket Word. It was then transferred to a DELL
Latitude notebook and modified as needed. this document is supposed to be HTML
V4.0 compliant.
