Ergonomics of human-system interaction - Part 125: Guidance on visual presentation of information (ISO 9241-125:2017)
ISO 9241-125:2017 provides guidance for the visual presentation of information controlled by software, irrespective of the device. It includes specific properties such as the syntactic or semantic aspects of information, e.g. coding techniques, and gives provisions for the organization of information taking account of human perception and memory capabilities. Those of its provisions that do not apply to specific types of visual interfaces clearly indicate any limitations to their applicability. It does not address specific details of charts, graphs or information visualization.
ISO 9241-125:2017 can be utilized throughout the design process (e.g. as specification and guidance for designers during design or as a basis for heuristic evaluation). Its provisions for the presentation of information depend upon the visual design approach, the task, the user, the environment and the single or multiple technologies that might be used for presenting the information. Consequently, this document cannot be applied without knowledge of the context of use. It is not intended to be used as a prescriptive set of rules to be applied in its entirety but rather assumes that the designer has proper information available concerning task and user requirements and understands the use of available technology.
Some of the provisions of this document are based on Latin-based language usage and might not apply, or might need to be modified, for use with languages that use other alphabets. In applying those that assume a specific language base (e.g. alphabetic ordering of coding information, items in a list), it is important that care is taken to follow its intent of the standard when translation is required to a different language.
ISO 9241-125:2017 does not address auditory or tactile/haptic presentation of information or modality shifting for the presentation of visual information in other modalities.
NOTE ISO 9241‑112 provides high-level ergonomic guidance that applies to all modalities.
Ergonomie der Mensch-System-Interaktion - Teil 125: Anleitung zur visuellen Informationsdarstellung (ISO 9241-125:2017)
Dieses Dokument enthält eine Anleitung für die visuelle Darstellung von Informationen, welche über eine Software (ungeachtet des Geräts) gesteuert wird. Es enthält bestimmte Eigenschaften wie syntaktische oder semantische Aspekte von Informationen, z. B. Kodierungsmethoden, und enthält Bestimmungen für die Organisation von Informationen unter Berücksichtigung der menschlichen Wahrnehmung und der Gedächtnisleistungen. Für diejenigen Bestimmungen, die nicht auf bestimmte Arten von visuellen Schnittstellen anwendbar sind, werden jegliche Beschränkungen hinsichtlich der Anwendbarkeit klar herausgestellt. Besondere Einzelheiten zu Tabellen, Diagrammen oder der Visualisierung von Informationen werden nicht behandelt.
Dieses Dokument kann während des Entwicklungsprozesses herangezogen werden (z. B. als Spezifikation und Anleitung für Entwickler während der Entwicklungsphase oder als Basis für eine heuristische Bewertung). Die Bestimmungen für die Darstellung von Informationen in diesem Dokument hängen vom Ansatz der visuellen Gestaltung, der Aufgabe, dem Benutzer, der Umgebung und der Technologie bzw. den Technologien ab, die zur Darstellung dieser Informationen verwendet werden. Folglich kann dieses Dokument nicht ohne Kenntnis des Nutzungskontextes angewandt werden. Die Norm ist nicht als vorschreibendes Regelwerk gedacht, das in seiner Gänze Anwendung zu finden hat, sondern geht vielmehr davon aus, dass der Entwickler über angemessene Informationen hinsichtlich der Aufgaben- und Nutzungsanforderungen verfügt und die Anwendung der verfügbaren Technologie versteht.
Einige der Bestimmungen in diesem Dokument basieren auf der Verwendung von Sprachen des lateinischen Schriftsystems und können unter Umständen nicht auf Sprachen mit anderen Alphabeten angewandt werden bzw. müssen ggf. für diese angepasst werden. Hinsichtlich der Anwendung dieser Bestimmungen, welche eine bestimmte Sprachbasis voraussetzen (z. B. eine alphabetische Anordnung von kodierten Informationen, Punkte in einer Liste), ist es wichtig sicherzustellen, dass die Intention dieser Norm berücksichtigt wird, wenn eine Übersetzung in eine andere Sprache notwendig ist.
Dieses Dokument behandelt keine akustische oder taktile/haptische Darstellung von Informationen oder Modalitätsänderungen für die Darstellung visueller Informationen in anderen Modalitäten.
ANMERKUNG ISO 9241 112 enthält übergeordnete ergonomiebezogene Empfehlungen, die auf alle Modalitäten anwendbar sind.
Ergonomie de l'interaction homme-système - Partie 125: Lignes directrices relatives à la présentation visuelle de l'information (ISO 9241-125:2017)
ISO 9241-125:2017 fournit un document d'orientation pour la présentation visuelle d'informations sous le contrôle d'un logiciel, indépendamment du support. Il inclut des propriétés spécifiques telles que les aspects syntaxiques ou sémantiques des informations, par exemple les techniques de codage, et fournit des dispositions relatives à l'organisation des informations en tenant compte des capacités humaines de perception et de mémorisation. Les dispositions qui ne s'appliquent pas à des types spécifiques d'interfaces visuelles indiquent clairement les éventuelles limites de leur applicabilité. Ne sont pas concernés les détails spécifiques des tableaux, des graphiques ou ceux de la visualisation des informations.
ISO 9241-125:2017 peut être utilisé au cours de l'ensemble du processus de conception (par exemple sous la forme de spécifications et de recommandations pour les concepteurs durant la conception ou en tant que base pour une évaluation heuristique). Ses dispositions relatives à la présentation des informations dépendent de l'approche de la conception visuelle, de la tâche, de l'utilisateur, de l'environnement ainsi que des technologies, simples ou multiples, qui peuvent être utilisées pour présenter les informations. Par conséquent, le présent document ne peut pas être appliqué sans connaître le contexte d'utilisation. Il n'est pas conçu pour être utilisé comme un ensemble de règles prescriptives à appliquer dans son intégralité, mais suppose plutôt que le concepteur dispose d'informations appropriées concernant la tâche et les exigences de l'utilisateur et comprend l'utilisation de la technologie disponible.
Certaines des dispositions du présent document se basent sur l'utilisation d'une langue d'origine latine et leur utilisation avec une langue utilisant un autre alphabet peut s'avérer impossible, ou éventuellement nécessiter une modification. En appliquant celles qui supposent une base linguistique spécifique (par exemple ordre alphabétique des informations de codage, des éléments d'une liste), il est important de veiller à respecter l'esprit de la norme lorsqu'une traduction dans une autre langue est exigée.
ISO 9241-125:2017 ne concerne pas la présentation auditive ou tactile/haptique des informations, ni le transfert de modalité à une fin de présentation d'informations visuelles dans d'autres modalités.
NOTE L'ISO 9241‑112 contient des recommandations ergonomiques de haut niveau qui s'appliquent à toutes les modalités.
Ergonomija medsebojnega vpliva človek-sistem - 125. del: Navodilo za vizualen prikaz informacij (ISO 9241-125:2017)
Standard ISO 9241-125 določa zahteve in priporočila za vizualen prikaz informacij in posebnih lastnosti, kot so sintaktični ali semantični vidiki informacij, npr. tehnike kodiranja. Te zahteve in priporočila je mogoče uporabiti skozi celotni postopek načrtovanja (npr. kot specifikacije in smernice za načrtovalce med načrtovanjem, osnova za hevristično vrednotenje). Ta mednarodni standard se uporablja za vse vizualne uporabniške vmesnike, ki jih nadzira programska oprema. Zahteve ali priporočila, ki se ne uporabljajo za vse vrste vizualnih vmesnikov, jasno kažejo kakršne koli morebitne omejitve njihove uporabe. Prikaz informacij je odvisen od pristopa vizualnega načrtovanja, naloge, uporabnika, okolja in posameznih ali več tehnologij, ki se lahko uporabijo za prikaz informacij. Zato standarda ISO 9241-125 ni mogoče uporabljati brez poznavanja konteksta uporabe in standard ni namenjen za uporabo kot predpisan nabor pravil, ki jih je treba uporabljati v celoti. Namesto tega predpostavlja, da ima načrtovalec na voljo ustrezne informacije o nalogah in uporabniških zahtevah ter razume uporabo razpoložljive tehnologije. Nekatere zahteve in priporočila v tem mednarodnem standardu temeljijo na uporabi jezikov, ki temeljijo na latinščini, in se morda ne uporabljajo ali jih je treba spremeniti za uporabo z drugim jezikom. Pri uporabi teh zahtev in priporočil, pri katerih je predvidena določena jezikovna osnova (npr. abecedno urejanje kodirnih informacij, postavk na seznamu), je pomembno upoštevati namen standarda, če je potreben prevod v drug jezik. Standard ISO 9241-125 ne obravnava zvočnih ali taktilnih/haptičnih prikazov informacij ali spremembe modalitete za prikaz vizualnih podatkov v drugih modalitetah.

Overview
EN ISO 9241-125:2017 (ISO 9241-125:2017) is part of the ISO 9241 family on ergonomics of human‑system interaction. It provides guidance for the visual presentation of information controlled by software, independent of device type. The document focuses on how information should be structured, coded and presented to match human perception and memory capabilities. It is guidance‑oriented rather than a prescriptive checklist and must be applied with knowledge of the specific context of use (task, user, environment, and technology).
Key topics and technical requirements
The standard addresses a broad set of visual presentation issues and design concerns, including:
- Visual structuring of information
- Arranging and labelling information, consistent location of areas, density and grouping
- Sequencing, use of conventions and functional grouping for rapid detection
- Legibility and display characteristics
- Legibility of characters and symbols, character height, and scaling of visual information
- User interface elements and organization
- Lists, tables, entry fields: structure, spacing, headings, item separation, numbering and continuation cues
- Window management: identification, default parameters, consistent appearance, resizing, placement and relationships between primary/secondary windows
- Labeling and wording
- Label position, grammatical construction, separation of labels and associated information, units of measurement
- Accessibility and language considerations
- Guidance on accessibility and notes that some provisions assume Latin‑based languages and may require modification for other scripts
- Scope limitations
- Explicitly does not address auditory or tactile/haptic presentation or detailed techniques for charts, graphs or advanced information visualization
The standard is intended as guidance, usable as design specifications or as the basis for heuristic evaluation; it flags which provisions are inapplicable to certain interfaces.
Applications
EN ISO 9241-125 is practical for:
- UX/UI designers and interaction designers creating desktop, web or mobile interfaces
- Software developers and front‑end engineers implementing forms, dashboards, menus and windows
- Usability specialists and HCI researchers conducting heuristic evaluations and accessibility reviews
- Product managers and systems architects defining information presentation requirements Typical uses: form and data entry design, table and list presentation, label and unit conventions, and window/dialog behavior across sessions and applications.
Who should use this standard
- UX/HCI professionals, accessibility experts, software teams, and standards assessors who need device‑agnostic ergonomic guidance on how visual information should be organized and presented.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

This first edition of ISO 9241-125, together with ISO 9241-112, cancels and replaces ISO 9241-12:1998,
which has been technically revised with the following changes:
— specific guidance relating to the presentation of visual information has been updated and extended
(recommendations for presentation of information in other modalities will be addressed in future
parts of ISO 9241);
— the characteristics of presented information have been elaborated with respect to ISO 9241-112;
— textual descriptions of the figures (alt text) have been added to enhance accessibility for sight-
impaired users (in PDF, these are “pop-ups” which appear when the cursor is passed over the figure).

Introduction
ISO 9241 is a multi-part International Standard that deals with both the hardware and software
ergonomic aspects of human-system interaction.
ISO 9241-125 is intended for use by the following types of users:
a) the user interface designer, who will apply it during the development process.
b) the buyer, who will reference it during the product procurement process, and whose end users will
gain from the potential benefits it provides.
c) project managers who are responsible for managing de
...
The article discusses ISO 9241-125, which provides requirements and recommendations for the visual presentation of information in human-system interaction. This includes aspects such as coding techniques. The standard applies to all visual user interfaces controlled by software, but it acknowledges that certain requirements or recommendations may not be applicable to all types of interfaces. The presentation of information depends on factors such as visual design, task, user, environment, and technologies used. Therefore, ISO 9241-125 cannot be applied without considering the context of use. It is not meant to be a strict set of rules, but assumes that designers have proper information and understanding of task and user requirements and available technology. Some requirements and recommendations are based on Latin-based language usage and may need modification for different languages. When translating to a different language, it is important to follow the intent of the standard. However, ISO 9241-125 does not cover auditory or tactile/haptic presentation of information, nor modality shifting to present visual information in other modalities.
ISO 9241-125은 정보의 시각적 표현과 구문적 또는 의미론적 측면과 같은 특정 속성에 대한 요구사항과 권고사항을 제공합니다. 이러한 요구사항과 권고사항은 설계 과정 전체에서 활용될 수 있으며(예: 설계 중 디자이너에 대한 명세 및 가이드로서 사용하거나 휴리스틱 평가의 기초로 사용될 수 있음), 소프트웨어로 제어되는 모든 시각적 사용자 인터페이스에 적용됩니다. 모든 종류의 시각적 인터페이스에 적용되지 않는 요구사항이나 권고사항은 해당 적용 가능성의 제약 사항을 명확히 나타냅니다. 정보의 표현은 시각적 설계 접근법, 작업, 사용자, 환경, 정보 제공에 사용될 수 있는 단일 또는 다중 기술에 따라 달라집니다. 따라서 ISO 9241-125는 사용 맥락에 대한 정보를 알고 있어야만 적용할 수 있으며, 전체적으로 적용해야 할 규칙의 목록으로 사용되는 것을 의도하지 않고 있습니다. 대신, 설계자는 작업과 사용자 요구사항에 대한 적절한 정보가 있으며 사용 가능한 기술의 사용법을 이해한다고 가정합니다. 이 국제 표준의 일부 요구사항과 권고사항은 라틴 언어 사용 방식을 기반으로 하고 있으며, 다른 언어에 대해서는 적용되지 않거나 수정이 필요할 수 있습니다. 특정 언어 기반을 가정하는 요구사항 및 권고사항(예: 코딩 정보의 알파벳 순서, 목록에 있는 항목)을 적용할 때는 다른 언어로 번역할 때 의도를 지키기 위해 신중함이 필요합니다. 하지만 ISO 9241-125은 정보의 청각적인 또는 촉각적/감각적 표현 또는 시각 정보를 다른 매체로 제공하기 위한 모드 전환에 대해 다루지 않습니다.
ISO 9241-125は、情報の視覚的表現や情報の統語的または意味論的側面など、特定の特性に関する要件と推奨事項を提供しています。これらの要件と推奨事項は、設計プロセス全体で活用できます（例えば、設計中のデザイナーへの仕様やガイドとしての利用、ヒューリスティック評価の基礎として利用可能）。ソフトウェアで制御されるすべての視覚的ユーザーインターフェースに適用されますが、すべてのタイプのインターフェースに適用されない要件や推奨事項は、その適用可能性の制約を明示します。 情報の表示は、視覚的デザインのアプローチ、タスク、ユーザー、環境、情報の提供に使用される単一または複数の技術に依存します。したがって、ISO 9241-125は使用の文脈を理解することなしには適用できません。全体的な規則セットとして使用することを意図していません。代わりに、設計者が適切な情報と利用可能な技術の使用方法に関する理解を持っており、タスクとユーザーの要件を把握していることを前提としています。 この国際規格の一部の要件と推奨事項は、ラテン語言語の使用方法に基づいており、異なる言語では適用されない場合があります。特定の言語ベースを想定した要件や推奨事項（例：コーディング情報のアルファベット順序、リスト内のアイテム）を異なる言語に翻訳する場合は、意図を守るために注意する必要があります。 ただし、ISO 9241-125は、情報の音声的または触覚/触覚的な表示、視覚情報を他のモードで表示するためのモード切り替えには対応していません。
