Ergonomics of human-system interaction - Part 126: Guidance on the presentation of auditory information (ISO/TS 9241-126:2019)

Edition date: 2022-03-23
In Force
Summary: This document provides guidance for the auditory 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. This document does not address the hardware issues of the transmission and the production of auditory information. NOTE 1 Volume is dependent on hardware and thus cannot always be absolutely controlled by software. Environmental conditions can also affect the ability for sounds to be perceived, which can be beyond the ability of the software to take into account. This document does not apply to auditory alarms, warnings or other safety-related uses of auditory information. NOTE 2 Safety-related uses of auditory presentation of information are covered in various domain specific standards, such as ISO 7731:2003 which deals with auditory danger signals for public and work areas, and IEC 60601-1-8:2006 which provides very specific requirements for auditory alarms for medical devices. While this document applies to the presentation of all non-safety-related information, it does not include application domain specific guidance (e.g., audio instructions for consumer products). This document 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 on the auditory design approach, the task, the user, the environment and the single or multiple technologies that can 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. This document does not address visual or tactile/haptic presentation of information or modality shifting for the presentation of auditory information in other modalities. NOTE 3 ISO 9241-112 provides high-level ergonomic guidance that applies to all modalities.

Dieses Dokument enthält Leitlinien für die auditive Darstellung von Informationen, die über eine Software (ungeachtet des Geräts) gesteuert wird. Es enthält bestimmte Eigenschaften wie syntaktische oder semantische Aspekte von Informationen, z. B. Codierungsmethoden, sowie Bestimmungen für die Organisation von Informationen unter Berücksichtigung menschlicher Wahrnehmung und Gedächtnis-leistungen. Dieses Dokument beschäftigt sich nicht mit hardwaretechnischen Fragen im Zusammenhang mit der Übertragung und Erzeugung auditiver Informationen. ANMERKUNG 1 Die Lautstärke ist hardwareabhängig und kann daher nicht immer vollständig über Software gesteuert werden. Auch Umgebungsbedingungen können sich auf die Fähigkeit zur Wahrnehmung von Klängen auswirken, was die Software gegebenenfalls nicht berücksichtigen kann. Dieses Dokument gilt nicht für akustische Alarmsignale, Warnsignale oder die sonstige sicherheitstechnische Verwendung auditiver Informationen. ANMERKUNG 2 Die sicherheitstechnische Verwendung auditiver Informationsdarstellung wird in verschiedenen bereichsspezifischen Normen behandelt, darunter ISO 7731:2003, die sich mit akustischen Gefahrensignalen für öffentliche Bereiche und Arbeitsstätten beschäftigt, und IEC 60601 1 8:2006, die sehr spezifische Anforderungen für akustische Alarmsignale von medizinischen elektrischen Geräten bereitstellt. Dieses Dokument gilt zwar für die Darstellung aller Informationen, die nicht sicherheitstechnischer Natur sind, enthält jedoch keine Anwendungsbereich-spezifischen Leitlinien (z. B. Audioanweisungen für Konsum¬güter). Dieses Dokument kann während des Entwicklungsprozesses herangezogen werden (z. B. als Spezifikation und Leitfaden für Entwickler während der Entwicklungsphase oder als Basis für eine heuristische Bewertung). Die Bestimmungen für die Darstellung von Informationen in diesem Dokument hängen von dem Ansatz der auditiven Gestaltung, der Aufgabe, dem Benutzer, der Umgebung und der Technologie bzw. den Technologien ab, die zur Darstellung dieser Informationen verwendet werden können. Folglich kann dieses Dokument nicht ohne Kenntnis des Nutzungskontextes angewendet werden. Es ist nicht als vorschreibendes Regelwerk gedacht, das in seiner Gänze anzuwenden ist, sondern geht vielmehr davon aus, dass der Entwickler über angemessene Informationen hinsichtlich der Aufgaben- und Benutzeranforderungen verfügt und die Anwendung der verfügbaren Technologie versteht. Dieses Dokument behandelt keine visuelle oder taktile/haptische Darstellung von Informationen oder Modalitätsänderungen für die Darstellung auditiver Informationen in anderen Modalitäten. ANMERKUNG 3 ISO 9241 112 enthält übergeordnete ergonomiebezogene Empfehlungen, die auf alle Modalitäten anwendbar sind.

Le présent document fournit des recommandations pour la présentation auditive 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. Le présent document ne traite pas des problèmes matériels de la transmission ni de la production des informations auditives. NOTE 1 Le volume est dépendant du matériel et ne peut donc pas toujours être sous le contrôle total du logiciel. Les conditions environnementales peuvent également affecter la perceptibilité des sons, ce que le logiciel n'est pas forcément en mesure de prendre en compte. Le présent document ne s'applique pas aux alarmes et avertissements auditifs ou autres utilisations d'informations auditives liées à la sécurité. NOTE 2 Les utilisations d'informations auditives à des fins de sécurité sont couvertes par différentes normes de domaine spécifiques, telles que l'ISO 7731:2003 qui traite des signaux de danger auditifs pour les lieux publics et les lieux de travail, et l'IEC 60601-1-8:2006 qui établit des exigences très précises pour les alarmes auditives des dispositifs médicaux. Si le présent document s'applique à la présentation de toutes les informations auditives non liées à la sécurité, il n'inclut toutefois pas de recommandations spécifiques aux différents domaines d'application (par exemple, instructions audio pour biens de consommation). Le présent document 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 auditive, 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. Le présent document ne concerne pas la présentation visuelle ou tactile/haptique des informations, ni le transfert de modalité à une fin de présentation d'informations auditives dans d'autres modalités. NOTE 3 L'ISO 9241-112 contient des préconisations ergonomiques de haut niveau qui s'appliquent à toutes les modalités.
