Ergonomics of human-system interaction - Part 129: Guidance on software individualization (ISO 9241-129:2010)

ISO 9241-129:2010 provides ergonomics guidance on individualization within interactive systems, including recommendations on where individualization might be appropriate or inappropriate and how to apply individualization.
It focuses on individualization of the software user interface to support the needs of users as individuals or as members of a defined group. It does not recommend specific implementations of individualization mechanisms. It provides guidance on how the various aspects of individualization are made usable and accessible, but does not specify which individualizations are to be included within a system. (Individualizations depend on the specific context of use for which an interactive system is to be designed and/or used, and need to be developed for that specific context of use.)
ISO 9241-129:2010 is not intended to be used in isolation. It deals only with individualization within the context of designing a complete software system. It is intended to be used with ISO 9241-110 and any other parts in the ISO 9241 series applicable to the design of the intended system.
Some of its guidance can also be applied to hardware user interfaces and user interfaces that combine software and hardware.

Ergonomie der Mensch-System-Interaktion - Teil 129: Leitlinien für die Individualisierung von Software (ISO 9241-129:2010)

Dieser Teil von ISO 9241 stellt Ergonomieleitlinien für die Individualisierung als Teil interaktiver Systeme zur
Verfügung, einschließlich Empfehlungen darüber
⎯ wo eine Individualisierung angebracht oder nicht angebracht sein könnte, und
⎯ wie die Individualisierung anzuwenden ist.
Er konzentriert sich auf die Individualisierung der Softwarebenutzungsschnittstellen, um die Bedürfnisse der
Benutzer als Einzelpersonen oder als Mitglieder einer bestimmten Zielgruppe zu unterstützen.
Er gibt keine Empfehlungen für spezifische Implementierungen von Mechanismen zur Individualisierung. Er
stellt Leitlinien zur Verfügung, wie verschiedene Aspekte der Individualisierung nutzbar und zugänglich
gemacht werden, spezifiziert jedoch nicht, welche Individualisierungen in ein System einzubinden sind.
ANMERKUNG Individualisierungen beruhen auf den spezifischen Nutzungskontext für den ein interaktives System
gestaltet und/oder genutzt wird und sollen für diesen spezifischen Nutzungskontext entwickelt werden.
Dieser Teil von ISO 9241 ist nicht für eine isolierte Anwendung vorgesehen. Er behandelt lediglich die
Individualisierung innerhalb des Kontexts der Gestaltung eines kompletten Softwaresystems. Er ist für die
gemeinsame Anwendung mit ISO 9241-110 und jedem anderen Teil der Normenreihe ISO 9241 vorgesehen,
die anwendbar auf die Gestaltung des geplanten Systems sind.
Einige Leitlinien dieses Teiles von ISO 9241 können auch bei Benutzungsschnittstellen angewendet werden,
die Software und Hardware miteinander verbinden.

Ergonomie de l'interaction homme-système - Partie 129: Lignes directrices relatives à l'individualisation des logiciels (ISO 9241-129:2010)

L'ISO 9241-129:2010 fournit des lignes directrices ergonomiques sur l'individualisation au sein des systèmes interactifs, et notamment des recommandations concernant les cas où l'individualisation pourrait être appropriée ou non, et concernant la manière de mettre en oeuvre l'individualisation.
Elle est centrée sur l'individualisation de l'interface utilisateur logicielle pour répondre aux besoins des utilisateurs en tant qu'individus ou membres d'un groupe défini. Elle ne recommande pas de mises en oeuvre spécifiques des mécanismes d'individualisation. Elle fournit des lignes directrices sur la manière dont les divers aspects de l'individualisation sont rendus utilisables et accessibles, mais elle ne spécifie pas quelles individualisations inclure dans un système. (Les individualisations dépendent du contexte spécifique d'utilisation pour lequel un système interactif est conçu et/ou utilisé, et doivent être développées pour ce contexte d'utilisation spécifique.)
L'ISO 9241-129:2010 n'est pas destinée à être utilisée seule. Elle traite uniquement de l'individualisation dans le contexte de la conception d'un système logiciel complet. Elle est destinée à être utilisée avec l'ISO 9241-110 et toute autre partie de la série ISO 9241 applicable à la conception du système concerné.
Certaines de ses lignes directrices peuvent également s'appliquer aux interfaces utilisateur matérielles et à celles combinant logiciel et matériel.

Ergonomija medsebojnega vpliva človek-sistem - 129. del: Navodilo za individualizacijo programske opreme (ISO 9241-129:2010)

Ta del ISO 9241 določa vodilo glede ergonomije na temo individualizacije v interaktivnih sistemih, vključno s priporočili glede tega,
- kje je individualizacija primerna ali neprimerna in
- kako individualizacijo uvesti.
Osredotoča se na individualizacijo uporabniške vmesniške programske opreme v podporo potrebam uporabnikov kot posameznikov ali kot članov določene skupine. Ne priporoča posebnih uvedb mehanizmov individualizacije. Podaja vodilo o tem, kako različni vidiki individualizacije postajajo uporabni in dostopni, vendar ne opredeljuje kakšne individualizacije naj bi bile vključene v sistem. OPOMBA: Individualizacije so odvisne od določenega konteksta uporabe, za katerega je interaktivni sistem načrtovan in/ali uporabljen ter se morajo razvijati za ta določen kontekst uporabe. Ta del ISO 9241 ni namenjen izolirani uporabi. Obravnava zgolj individualizacijo v kontekstu načrtovanja celotnega sistema programske opreme. Namenjen je uporabi skupaj z ISO 9241-110 in drugimi deli skupine ISO 9241, ki veljajo za načrtovanje predvidenega sistema. Del vodila se lahko uporabi tudi za uporabniške vmesnike za strojno opremo in uporabniške vmesnike, ki kombinirajo programsko in strojno opremo.

ISO 9241-129:2010(E) © ISO 2010 – All rights reserved v 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. 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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 9241-129:2010(E) © ISO 2010 – All rights reserved vii Introduction Individualization is used in a wide variety of ways to enhance applications both for users and for branding of the applications themselves. The wide variety of different implementations includes many instances where individualization creates considerable challenges for the users that it ought to be helping. This becomes an even greater challenge when users have to deal with different individualization approaches in each of the several applications that they use. The purpose of this part of ISO 9241 is to provide guidance on the application of software individualization in order to achieve as high a level of usability as possible. Thus it addresses individualization as the modification of interaction and presentation of information to suit individual capabilities and needs of users. Individualization enables support of a wide range of users, tasks, and contexts of use. It is particularly useful in increasing accessibility (which is discussed in ISO 9241-171). On the one hand, ISO 9241-110 provides general guidance on individualization, identifying it as one of the seven dialogue principles that are important for the design and evaluation of interactive systems. On the other hand, this part of ISO 9241 provides considerably more detail on the ergonomic use of individualization. This part of ISO 9241 addresses both user-initiated and system-initiated individualization. It encompasses the concepts of configuration, customization, adaptivity, adaptation, profiling, and internationalization. It serves the following types of users: ⎯ designers of user-interface development tools and style guides to be used by interface designers; ⎯ user-interface designers, who will apply the guidance during the development process; ⎯ developers, who will apply the guidance during the design and implementation of system functionality; ⎯ system administrators responsible for implementing solutions to meet end-user needs; ⎯ buyers, who will reference this part of ISO 9241 during product procurement; ⎯ evaluators, who are responsible for ensuring that products are in accordance with this part of ISO 9241. The ultimate beneficiary of this part of ISO 9241 will be the end-user of the software. Although it is unlikely that end-users will read this part of ISO 9241, its application by designers, developers, buyers and evaluators ought to provide user interfaces that are more usable through the use of individualization. This part of ISO 9241 concerns the development of software for user interfaces. However, those involved in designing the hardware aspects of user interfaces may also find it useful when considering the interactions between software and hardware aspects.

INTERNATIONAL STANDARD ISO 9241-129:2010(E) © ISO 2010 – All rights reserved 1 Ergonomics of human-system interaction — Part 129: Guidance on software individualization 1 Scope This part of ISO 9241 provides ergonomics guidance on individualization within interactive systems, including recommendations on ⎯ where individualization might be appropriate or inappropriate, and ⎯ how to apply individualization. It focuses on individualization of the software user interface to support the needs of users as individuals or as members of a defined group. It does not recommend specific implementations of individualization mechanisms. It provides guidance on how the various aspects of individualization are made usable and accessible, but does not specify which individualizations are to be included within a system.

NOTE Individualizations depend on the specific context of use for which an interactive system is to be designed and/or used, and need to be developed for that specific context of use. This part of ISO 9241 is not intended to be used in isolation. It deals only with individualization within the context of designing a complete software system. It is intended to be used with ISO 9241-110 and any other parts in the ISO 9241 series applicable to the design of the intended system. Some of its guidance can also be applied to hardware user interfaces and user interfaces that combine software and hardware. 2 Normative references The following referenced documents are indispensable for the application of this document.

user interface object entity of the user interface that is presented to the user by the software EXAMPLE Text, graphic, control. NOTE 1 User-interface elements can be interactive or not. NOTE 2 Both entities relevant to the task and entities of the user interface are regarded as user-interface elements. A user-interface element can be a visual representation or an interaction mechanism for a task object (such as a letter, sales order, electronic part or wiring diagram) or a system object (such as a printer, hard disk or network connection). It can be possible for the user to directly manipulate some of these user-interface elements. NOTE 3 User-interface elements in a graphical user interface include such things as basic objects (such as window title bars, menu items, push buttons, image maps, and editable text fields) or containers (such as windows, grouping boxes, menu bars, menus, groups of mutually-exclusive option buttons, and compound images that are made up of several smaller images). User-interface elements in an audio user interface include such things as menus, menu items, messages, and action prompts. [ISO 9241-171:2008, 3.38] 4 Conformance If it is claimed that a system or service has met the provisions of this part of ISO 9241, then the procedures used to establish user requirements, to develop individualization capabilities and to evaluate the individualizations shall be specified. The level of detail of the specification is a matter of negotiation between the involved parties. Annex C provides assistance in documenting conformance. 5 Framework for applying this part of ISO 9241 The following clauses range from general high-level guidance (applicable to all uses of individualization) to specialized detailed guidance (applicable to specific instances of individualization). Clauses 6 and 7 provide general guidance related to the use and goals of individualization. They provide information that applies throughout the development of a system. Clauses 8, 9, and 10 provide guidance related to choice of individualization mechanisms, individualization of configurations and support of individual users.

Clauses 11, 12, and 13 provide guidance related to particular interfaces, components, and actions that might be involved in specific cases of individualization. SIST EN ISO 9241-129:2011

Figure 1 — Framework for the application of this part of ISO 9241 6 Introduction to individualization 6.1 The role of individualization Individualization involves modifying the behaviour of the interactive system and the presentation of its user interface elements, prior to use or while it is in use, to better meet characteristics of its context of use for an individual or a group of users. The capability to individualize should be built into an application in response to the identification of user requirements, i.e. different users can have different needs and/or individual users can have different needs at different times. Individualization refers to modifications that are achievable without reprogramming the application, because individualization capabilities have already been built into the application. NOTE More details on factors to consider when designing individualization can be found in Annex B. SIST EN ISO 9241-129:2011

ISO 9241-129:2010(E) © ISO 2010 – All rights reserved 5 6.2 When to provide the capability for individualization Individualization capabilities may be provided to accommodate one or more of the following, when a single design solution is not sufficiently usable. a) Variation in user characteristics 1) Differences in user characteristics (capabilities and preferences) that will increase accessibility i) within a user group, or

ii) between user groups EXAMPLE 1 A user group includes people with limited vision.
