There is a broad spectrum of
disabilities and constraints:
• Blind, visually impaired,
• Deaf, hard of hearing,
• Dyslectics,
• Elderly people,
• Quadriplegics ,
• Those affected by the Parkinson’s disease, those
suffering from vertigo…..
Several hundreds of millions worldwide
(= an economically significant market)

Read And Produce Information
►
The act of reading “written” information and
the act of producing “written” information
are twin elements of communication.
►
When talking about access to information,
we have to include both the access to the
authoring tools of information and the
production of information that is accessible.

The Vision of the DAISY Consortium
► “We envision a world where people
with print disabilities have equal
access to information and knowledge,
without delay or additional expense”
(DAISY Consortium).

Information Systems – There is
More than the Web
►
Besides the Web, there are other relevant
information systems to be taken into
account:
 Books and documents of any kind (libraries,
archives, book stores, posted on the web,
newspapers, magazines…
 Orthography and Scripture
 Scientific formulas… music scores…
 Lay outs

To Orientate Oneself in an
Information System – Fundamental
Prerequisite
►
Navigability – To know where I am, to go
without detour where I want to go, to
retrieve a specific point (in a book for
instance)
►
This is the fundamental pre-condition for
 any studies, knowledge acquisition, professional
formation, and autonomous and independent
living;
 social, economic, and political integration.

To Deny Access to Information
Constitutes a Grave Discrimination
►
Access to information is a Human Right
►
To deny a person the access to information
(which means to studies, professional
formation, and knowledge acquisition,
which equals to deny social, economical,
and political integration) constitutes a
grave discrimination of this person.
(“UN Convention on the Rights of Persons with
Disabilities”, 2006, entered into force on 3 May
2008, see especially Art. 9).

Different Perception Channels
(or a combination
of them) procure access to information:
 Blind persons: perception by hearing and/or by
tactile sensation (Braille)
 Visually impaired: perception by hearing and/or
zoom and contrast functionalities
 Dyslectics: simultaneous representation of the
written text and its audio version, slow down
functionality
 Deaf persons: Translation of the content into sign
language (video)
This leads to the concept of one content – multiple
medium layers - collected in one “place”.

The DAISY concept: Navigable and
Synchronized Multimedia - One Source
File
TEXT layer (“Extensible Markup Language”, XML, W3C
standard, separates the structural elements of the
content from its representations)
AUDIO layer
IMAGES
VIDEO layer (next version of the standard, 2010)
MUSIC SCORES (dreams of the future) are
 navigable (know where I am – go where I want
to) and
 synchronized by “Synchronized Multimedia
Integration Language” SMIL, W3C standard (which
provides flexibility in presentation and
dissemination of content).

One Has to Be Perfectly Aware of…
► The
DAISY standard is NOT limited
to talking books! This is
unfortunately a widespread
misconception that has to be
corrected imperatively.
► The
DAISY standard is a standard for
accessible MULTIMEDIA which is
navigable and synchronized
multimedia.

One Source File – Multiple Options
►
Many representation options (simultaneous
representation of the perception channel
layers or separating them):
Braille on paper and/or electronically; large print (customizable for
fonts, type sizes, contrasts) on paper and/or electronically); talking
books, eBooks, human or synthetic voice, etc.
►
Many play back options:
Stand alone devices, portable devices (including mobile phones,
PDA’s); devices with or without (Braille) displays; different sizes of
displays, software players, etc.
►
Many distribution options:
Physical mediums (CD, DVD, Memory Cards); download, streaming,
LAN, WLAN, broadcasting, TV, Internet.

DAISY Follows the “Universal Design”
Concept
"Universal design means the design of
products, environments, programs
and services to be usable by all
people, to the greatest extent
possible, without the need for
adaptation or specialized design.
Universal design shall not exclude
assistive devices for particular groups
of persons with disabilities where this
is needed.” (UN Convention on the Rights of
Persons with Disabilities, Art. 2)

Standardization is Key (1)
►
The access problem is universal – the
solution has to be universal as well.
►
The systems interoperability can only be
reached effectively through an open
standard and/or through compatible
standards.
►
A fragmentation of incompatible standards
would be a waste of resources with very
limited results in respect to quality and
spread.

Standardization is Key (2)
►
Without a maintained and continuously
further developed standard – no
sustainability.
►
Without a maintained and continuously
further developed standard – no
worldwide coverage
►
Without a maintained and continuously
further developed standard – no
sufficient quality of accessibility.

Standardization is Key (3)
►
With partial and isolated initiatives the coverage
is extremely limited; there are considerable
investments and only a few fruits.
►
Without a maintained and continuously further
developed standard – no profit for the industry
– no development of appropriate tools.
►
Without a maintained and continuously further
developed standard – the industry will not be
able to really comply with the political
demands.

Standardization is Key (4)
►
Without an available maintained and
continuously further developed standard – the
political sector will not be able to impose
its own demands.
►
A navigable and synchronized accessible
multimedia standard brings profit both to the
print disabled and the wide consumer
community – the market and the amount of
applications are unlimited.
Remark: There is a common understanding that
“accessibility” is a charitable service offered to
persons with disabilities.– We should look at it the
other way around. It is more appropriate to reverse the
thinking and to say:

A Gift Offered to the World
Accessible multimedia is a
gift offered by the print
disabled to the world.
Did you know that the typewriter was invented in
the 18th century for a blind lady who wanted to
communicate with others?

Some Ideas for Mainstream Products
►
In general: products that are making use of
different media by mixing for specific purposes
TEXT, AUDIO, IMAGES, VIDÉO, MUSIC
SCORES.
►
Class books and textbooks of any kind;
learning materials (learning of foreign
languages, mother tongue); contents of
curricula of any kind (history, sciences);
children’s books, etc.
►
Encyclopedias, tourist guides, museum guides,
cookery books, instruction manuals, etc.

Everybody is Invited to Participate
► The
more forces that work together the more progress will be tangible &
the more the profits for everybody
will increase.
►I
am inviting all sectors of society –
political, private, NGO and civil
society – to participate in the
standardization efforts and to join
the DAISY movement.
