Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 9241-12 was prepared by Technical Committee
ISO/TC 159, Ergonomics, Subcommittee SC 4, Ergonomics of human-
system interaction.
ISO 9241 consists of the following parts, under the general title Ergonomic
requirements for office work with visual display terminals (VDTs):
— Part 1: General introduction
— Part 2: Guidance on task requirements
— Part 3: Visual display requirements
— Part 4: Keyboard requirements
— Part 5: Workstation layout and postural requirements
— Part 6: Guidance on the work environment
— Part 7: Display requirements with reflections
— Part 8: Requirements for displayed colours
— Part 9: Requirements for non-keyboard input devices
— Part 10: Dialogue principles
— Part 11: Guidance on usability
— Part 12: Presentation of information
— Part 13: User guidance

Introduction
ISO 9241 is a multipart International Standard that deals with both the
hardware and software ergonomic aspects of the use of VDTs. The
description of the parts, their interrelationships, and a description of the
expected users of the parts is described in ISO 9241-1.
This part of ISO 9241 deals with the visual presentation of information
using visual display terminals (VDTs). It includes (in clause 4) design ob-
jectives which provide high level guidance on the presentation of infor-
mation. This part of ISO 9241 is concerned with the organization of
information and with the usage of coding techniques in order to improve
user performance and satisfaction. Clauses 5 to 7 provide recommen-
dations for display design and apply generally to all dialogue techniques.
This part of ISO 9241 can be used in conjunction with other forms of
guidance. For example, ISO 9241-10 ([2] in annex B) provides seven
principles, each of which can be supported by presenting information on
displays in appropriate ways.
This part of ISO 9241 serves the following types of users:
a) The user interface designer, who will apply this part of ISO 9241
during the development process.
b) The buyer, who will reference this part of ISO 9241 during the product
procurement process, and whose end-users will gain from the potential
benefits provided by the standard.
c) Those responsible for ensuring products meet the recommendations in
this part of ISO 9241.
d) Designers of user interface development tools to be used by interface
designers.
e) Writers of software industry standard guides to be used by interface
designers, for example, “interface style guides”.
Other common sources of guidance include software industry “interface
style guides”. Once technical issues about the nature of the system
hardware and software have been considered, additional guidance can be
provided which generally helps to increase the consistency of the interface
design. Typically, these industry style guides describe a specific way of
implementing the type of higher level general guidance offered in this part
of ISO 9241.
The ultimate beneficiary of this part of ISO 9241 will be the end-user at the
VDT. Although it is unlikely that the end-user will read this part of ISO 9241
or even know of its existence, its application by designers, buyers, and
evaluators should provide user interfaces that are more usable, consistent
and that enable greater productivity.

ISO ISO 9241-12:1998(E)
This part of ISO 9241 consists of general recommendations and conditional
recommendations concerning presentation of information. General rec-
ommendations apply to most users, tasks, environments, and technology.
In contrast, conditional recommendations are those that apply only within
the specific context for which they are relevant (e.g. particular kinds of
users, tasks, environments, technology). Conditional recommendations
have an "if-then" structure. The recommendations were developed primar-
ily by reviewing the existing relevant literature and empirical evidence, then
generalizing and formulating this work into recommendations for use by the
interface designer and/or evaluator.

Ergonomic requirements for office work with visual display
terminals (VDTs) —
Part 12:
Presentation of information
1 Scope
This part of ISO 9241 provides ergonomic recommendations for the presentation of information and specific
properties of presented information on text-based and graphical user interfaces used for office tasks. It provides
recommendations for the design and evaluation of visual presentation of information including coding techniques.
These recommendations can be utilized throughout the design process (for example as guidance for designers
during design, as a basis for heuristic evaluation, as guidance for usability testing). The coverage of colour is limited
to ergonomic recommendations for the use of colour for highlighting and categorizing information (see ISO 9241-8
for additional recommendations for the use of colour).
This part of ISO 9241 does not address auditory presentation of information.
Interface design depends upon the task, the user, the environment and the available technology. Consequently, this
part of ISO 9241 cannot be applied without a knowledge of the design and the context of use of the interface, and it
is not intended to be used as a prescriptive set of rules to be applied in its entirety. Rather, it assumes that the
designer has proper information available concerning task and user requirements and understands the use of
available technology (this may require consultation with a qualified ergonomics professional as well as empirical
testing with real users).
NOTE 1 Although this is an International Standard, some of the conditional recommendations are based on Latin-based
language usage and may not apply, or may need to be modified, for use with a different language. For example, in right-to-left
languages those conditional recommendations oriented towards left-to-right reading may need to be modified and adapted. In
applying those conditional recommendations that assume a specific language base (e.g. alphabetic ordering of coding
information, items in a list), care should be taken concerning the intent of this part of ISO 9241 when translation is required to a
different language.
NOTE 2 Providing users with the capability to alter the interface to suit their own needs has become a popular approach to
software interface design. This is often a desirable feature of the interface. However, providing users with customization
capabilities is not an acceptable substitute for an ergonomically designed interface (e.g. default windows, colour settings). Note
that customization of the presentation of information may result in deviations from this part of ISO 9241.
