Ergonomics of human-system interaction - Part 394: Ergonomic requirements for reducing undesirable biomedical effects of visually induced motion sickness during watching electronic images (ISO 9241-394:2020)

This document establishes the requirements and recommendations for image contents and electronic display systems to reduce visually induced motion sickness (VIMS), while viewing images on electronic displays.
This document is applicable to electronic display systems, including flat panel displays, projectors with a screen, and virtual reality (VR) type of head mounted displays (HMDs), but not including HMDs that present electronic images on/with real-world scenes.
NOTE 1  This document assumes the images are viewed under appropriate defined conditions. See Annex B for the appropriate viewing conditions.
NOTE 2  This document is useful for the design, development, and supply of image contents, as well as electronic displays for reducing VIMS.
NOTE 3  ISO 9241‑392[3] provides guidelines for stereoscopic 3D displays, of which the methods are also used in HMDs.
NOTE 4  The International Telecommunication Union (ITU) generally sets the standards for broadcasting.

Dieses Dokument legt die Anforderungen und Empfehlungen für Bildinhalte und elektronische Anzeigesysteme fest, um die visuell induzierte Bewegungskrankheit (VIMS) bei der Betrachtung von Bildern auf elektronischen Anzeigen zu reduzieren.
Dieses Dokument ist anwendbar für elektronische Anzeigesysteme, einschließlich Flachbildschirme, Projektoren mit einem Bildschirm und auf dem Kopf getragene Anzeigen (en: head mounted displays, HMDs) für virtuelle Realität (VR), jedoch nicht für auf dem Kopf getragene Anzeigen, die elektronische Bilder an oder mit realen Szenen darstellen.
ANMERKUNG 1   In diesem Dokument wird davon ausgegangen, dass die Bilder unter entsprechend definierten Bedingungen betrachtet werden. In Anhang B sind angemessene Betrachtungsbedingungen beschrieben.
ANMERKUNG 2   Dieses Dokument ist nützlich für die Gestaltung, Entwicklung und Bereitstellung von Bildinhalten sowie von elektronischen Anzeigen zur Reduzierung von VIMS.
ANMERKUNG 3   ISO 9241 392 [3] gibt Leitlinien für stereoskopische 3D-Anzeigen, deren Methoden auch in HMDs verwendet werden an.
ANMERKUNG 4   Die International Telecommunication Union (ITU) legt im Allgemeinen die Standards für die Ausstrahlung fest.

Ergonomie de l'interaction homme-système - Partie 394: Exigences ergonomiques pour la réduction des effets biomédicaux indésirables des cinétoses induites par stimulus visuel lors de l’observation d’images électroniques (ISO 9241-394:2020)

Le présent document établit les exigences et les recommandations pour les contenus d’images et les systèmes d’affichage électronique afin de réduire les cinétoses induites par stimulus visuel (VIMS), lors de la visualisation d’images sur des affichages électroniques.
Le présent document s’applique aux systèmes d’affichage électronique, y compris aux écrans plats, aux projecteurs avec un écran et aux casques stéréoscopiques (HMD) de type casque de réalité virtuelle (RV), mais pas aux HMD qui présentent des images électroniques sur/avec des scènes du monde réel.
NOTE 1        Le présent document suppose que les images sont visualisées dans des conditions définies appropriées. Voir Annexe B pour connaître les conditions de visualisation appropriées.
NOTE 2        Le présent document est utile pour la conception, le développement et la fourniture de contenus d’images, mais aussi d’affichages électroniques pour réduire les VIMS.
NOTE 3        L’ISO 9241‑392[3] fournit des lignes directrices pour les affichages 3D stéréoscopiques, dont les méthodes sont également utilisées dans les HMD.
NOTE 4        L’Union internationale des télécommunications (UIT) fixe généralement les normes pour la radiodiffusion.

Ta dokument določa zahteve in priporočila za slikovne vsebine in elektronske prikazovalne sisteme za zmanjšanje potovalne slabosti, ki jo povzročajo vizualni dražljaji (VIMS) pri gledanju slik na elektronskih prikazovalnikih.
Ta dokument se uporablja za elektronske prikazovalne sisteme, vključno s ploskovnimi zasloni, projektorji z zaslonom in naglavnimi prikazovalniki (HMD) navidezne resničnosti (VR), ne uporablja pa se za naglavne prikazovalnike, ki elektronske slike prikazujejo prek prizorov iz resničnega sveta ali skupaj z njimi.
OPOMBA 1:   Ta dokument predpostavlja, da se slike gledajo v ustreznih, opredeljenih pogojih. Za ustrezne pogoje gledanja glej dodatek B.
OPOMBA 2:   Ta dokument je uporaben za oblikovanje, razvoj in posredovanje slikovnih vsebin, kot tudi za elektronske prikazovalnike za zmanjšanje potovalne slabosti, ki jo povzročajo vizualni dražljaji.
OPOMBA 3:   Standard ISO 9241-392 vsebuje smernice za stereoskopske 3D-prikazovalnike, pri čemer se metode iz tega standarda uporabljajo tudi pri naglavnih prikazovalnikih.
OPOMBA 4:   Standard običajno pripravi Mednarodna zveza za telekomunikacije (ITU).

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
