Ergonomics of human-system interaction - Part 391: Requirements, analysis and compliance test methods for the reduction of photosensitive seizures (ISO 9241-391:2016)

ISO 9241-391:2016 provides requirements and recommendations for reducing photosensitive seizures (PSS), while viewing images on electronic displays.
The requirements and recommendations in this part of ISO 9241 are designed to be applied to image contents. By image contents, reference is made to the images independent of the device or environment in which they are displayed.
The requirements and recommendations in this part of ISO 9241 are for the protection of the vulnerable individuals in the viewing population who are photosensitive and who are therefore liable to seizures triggered by flashing lights and regular patterns, including certain repetitive images.
NOTE 1       ITU considers the image safety issues in relation to broadcasting. Some of these are described in ITU-R BT.1702.[2]
NOTE 2       There are some related recommendations in ISO/IEC 40500:2012, W3C Web Content Accessibility Guidelines (WCAG) 2.0, for web contents accessibility.
NOTE 3       Photosensitive seizures and photosensitive epilepsy, that is, chronic conditions characterized by those repeated seizures are medical conditions. Clinical aspects of photosensitivity appear in Annex C. Visually induced seizures are equivalent to PSS.

Ergonomie der Mensch-System-Interaktion - Teil 391: Anforderungen, Analysen und Prüfverfahren zur Konformität zur Verringerung epileptischer Anfälle aufgrund photosensitiver Reize (ISO 9241-391:2016)

Dieser Teil von ISO 9241 stellt Anforderungen und Empfehlungen zur Verminderung von Anfällen aufgrund photosensitiver Reize (PSS) bei der Betrachtung von Bildern auf elektronischen Anzeigegeräten bereit.
Die Anforderungen und Empfehlungen dieses Teils von ISO 9241 wurden für die Anwendung auf Bildinhalte entwickelt. Durch den Begriff „Bildinhalte“ wird auf die Bilder selber verwiesen, unabhängig von Anzeigegerät oder Umgebung, innerhalb derer sie angezeigt werden.
Die Anforderungen und Empfehlungen dieses Teils von ISO 9241 sind zum Schutz der verletzlichen Personen innerhalb der Bevölkerung gedacht, die lichtempfindlich sind und die daher anfällig für Anfälle, die durch aufblitzende Lichter und regelmäßige Muster, einschließlich bestimmter, sich wiederholender Bilder, ausgelöst werden.
ANMERKUNG 1   Die Internationale Fernmeldeunion (ITU) befasst sich mit den Sicherheitsaspekten von Bildern in Bezug auf deren Ausstrahlung. Einige dieser Aspekte werden in ITU-R BT.1702 [2] beschrieben.
ANMERKUNG 2   In ISO/IEC 40500:2012 [W3C Web Content Accessibility Guidelines (WCAG) 2.0] gibt es einige damit verbundene Empfehlungen hinsichtlich des Zugangs zu Inhalten des Internets.
ANMERKUNG 3   Anfälle aufgrund photosensitiver Reize und epileptische Anfälle bedeutet, dass die durch die wiederholten Anfälle gekennzeichneten, chronischen Zustände medizinische Zustände sind. Auf die klinischen Aspekte der Photosensibilität wird in Anhang C Bezug genommen. Visuell hervorgerufene Anfälle sind äquivalent zu PSS.

Ergonomie de l'interaction homme-système - Partie 391: Exigences, analyses et méthodes d'essai de conformité pour la réduction des saisies photosensibles (ISO 9241-391:2016)

ISO 9241-391:2016 spécifie des exigences et fournit des recommandations concernant la réduction des saisies photosensibles (SPS) lors de l'observation d'images sur des afficheurs électroniques.
Les exigences et les recommandations dans la présente partie de l'ISO 9241 sont destinées à être appliquées à des contenus d'images. Le terme «contenus d'images» fait référence aux images elles-mêmes, indépendamment du dispositif ou de l'environnement sur (dans) lequel elles sont affichées.
Les exigences et les recommandations fournies dans la présente partie de l'ISO 9241 sont destinées à la protection de la partie vulnérable de la population, qui risque de faire des crises d'épilepsie photosensible déclenchées par des flashs lumineux et des séquences répétitives, y compris certaines images répétitives.
NOTE 1       L'UIT étudie les problèmes liés à la sécurité des images par rapport à la télédiffusion. Certaines d'entre elles sont décrites dans la Recommandation UIT-R BT.1702.[2]
NOTE 2       Quelques recommandations pertinentes sont fournies dans l'ISO/IEC 40500:2012, Technologies de l'information ? Règles pour l'accessibilité des contenus Web (WCAG) 2.0 du World Wide Web Consortium (W3C) pour l'accessibilité des contenus Web.
NOTE 3       Les saisies photosensibles et l'épilepsie photosensible, c'est-à-dire des troubles chroniques caractérisés par des crises répétées, constituent des états pathologiques. Les aspects cliniques de la photosensibilité sont abordés dans l'Annexe C. Les crises induites par stimulus visuel sont équivalentes aux saisies photosensibles (SPS).

Ergonomija medsebojnega vpliva človek-sistem - 391. del: Zahteve, analize in preskusne metode za ugotavljanje skladnosti za zmanjšanje epileptičnih napadov, sproženih s fotosenzitivnimi dražljaji (ISO 9241-391:2016)

Ta del standarda ISO 9241 podaja smernice za zmanjševanje epileptičnih napadov, sproženih s fotosenzitivnimi dražljaji, enega od treh največjih neželenih biomedicinskih učinkov, ki jih sprožajo slike, predstavljene na elektronskih vizualnih zaslonih. Smernice opisujejo pogoje, ki jih v osnovi ustvarjajo elektronske vizualne slikovne vsebine, predstavljene v domačih in delovnih okoljih, vendar ne na elektronskih vizualnih zaslonih. Smernica v dokumentu je namenjena zaščiti ranljivega dela populacije gledalcev, ki so občutljivi na fotosenzitivne dražljaje ter so zato nagnjeni k epileptičnim napadom, ki jih sprožijo utripajoče lučke in enakomerni vzorci, vključno z določenimi vrstami ponavljajočih slik.

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.
