6. 9.2 Multi-media Publication
Structure
An important consideration in multimedia
usability is structure. If the user does not
understand the structure, there will be
confusion and usage of the product will be
impaired.
Although in practice, publications are not
confined to one structure, a general
understanding of the types of structures
available and their attributes can aid in
multimedia design.

7. 9.2 Multi-media Publication
Structure
Linear Structure
The traditional structure, and one that most familiar.
Each piece of the information is to be viewed in a
fixed position that is essential to its understanding.
Time-based media such as film, television or radio
broadcast are linear in structure.
A linear structure is necessary to tell a story and can
be effective when trying to achieve set goals as in
educational projects.

Structure
Hierarchical
Structure
Each node of the
structure represents an
idea and may have
subordinate nodes that
expand on part of the
parent nodes.
This type of structure is
particularly useful for
reference material
where a user may

in a linear fashion and
then easily go deep into
areas of interest without
too much confusion.

continue through one

attain the same amount of
information.
An example of this might
be a public information

a small explanation of each
exhibit in a room.

11. 9.3 Navigational Aids
The usability of a publication depends not only on the
structure and links chosen, but also on the user's
knowledge of the system and the usefulness of the
navigation aids.
A user will feel lost if he or she has no way of
orienting him or herself.
Aids such as path lists allow the user to establish
where they have come from while a graphical
representation of the accessible system can indicate
the location overall.
Aids such as alphabetical content lists or hierarchical
tables of contents can also assist the user.

12. 9.4 Publication considerations
There are many processes in producing a multi-media
publication.
The following is a checklist of points which should be
considered:
completion of manuscript
possible conversion of manuscript if necessary into a
different document type
author and date registration
ensure all necessary components are received, i.e. for
metadata, keywords, etc.
ensure verification tools are provided or referenced
texts may have to be translated/corrected/checked
compile all graphic designs: labels; covers; sites, web
pages, icons, navigational tools, logos, etc.
12
13. 9.4 Publication considerations
ensure all cross-links are included and correct, this is
especially important in the case of a hybrid
publication
ensure all hyperlinks are in place and correct (there
are tools available for checking the validity of links);
technical advice/suitability for conversion
draw up any necessary subscription licenses
ensure any E-mail ordering facilities or any support
services are in place
set realistic publication deadlines and schedule
follow specified production procedures
allow time for hard-copy proof-reading to pick up any
errors before publication.
