Ergonomics of human-system interaction - Part 392: Ergonomic recommendations for the reduction of visual fatigue from stereoscopic images (ISO 9241-392:2015)

ISO 9241-392:2015 establishes recommendations for reducing the potential visual discomfort and visual fatigue experienced during viewing of stereoscopic images under defined viewing conditions. Visual fatigue and discomfort might be produced by the stereoscopic optical stimulus of disparate images that were presented binocularly.
ISO 9241-392:2015 is also applicable to the final products of stereoscopic presentations which depend on stereoscopic image content and stereoscopic displays when viewed under appropriate defined conditions. Therefore, the recommendations are intended for people responsible for the design, development, and supply of stereoscopic image content as well as stereoscopic displays.
NOTE 1       See Annex B for appropriate viewing conditions.
The recommendations in this part of ISO 9241 are applicable to stereoscopic displays such as those with glasses and two-view autostereoscopic displays, stereoscopic head-mounted displays, and stereoscopic projectors. Moreover, they are applicable to stereoscopic image content intended to be presented on the above-mentioned stereoscopic displays and stereoscopic presentations that are realized by the combinations of these images and displays.
NOTE 2       Annex C presents numerical criteria as an informative reference.
NOTE 3       Other guidance might need to be established by referring to this part of ISO 9241 when requirements and recommendations specific to each type of stereoscopic image content or stereoscopic display become necessary.
NOTE 4       ITU generally sets the standards for broadcasting.
NOTE 5       ISO 9241‑303:2011, Annex E provides guidelines for virtual displays which are intended for stereoscopic head-mounted displays.

Ergonomie de l'interaction homme-système - Partie 392: Exigences ergonomiques pour diminuer la fatigue visuelle induite par des images stéréoscopiques (ISO 9241-392:2015)

L'ISO 9241-392:2015 fournit des recommandations visant à réduire la gêne et la fatigue visuelles éventuelles ressenties lors de l'observation d'images stéréoscopiques dans des conditions d'observations définies. La gêne et la fatigue visuelles peuvent être dues au stimulus optique stéréoscopique d'images disparates présentées de façon binoculaire.
L'ISO 9241-392:2015 est également applicable aux produits finaux des présentations stéréoscopiques, lesquels dépendent des contenus d'images stéréoscopiques et des écrans stéréoscopiques, lorsque ceux-ci sont observés dans des conditions définies appropriées. En conséquence, les recommandations concernent les personnes en charge de la conception, du développement et de la fourniture de contenus d'images stéréoscopiques; elles concernent également les écrans stéréoscopiques.
Les recommandations de l'ISO 9241-392:2015 sont applicables aux écrans stéréoscopiques, tels que ceux utilisant des lunettes stéréoscopiques, des écrans autostéréoscopiques deux-vues, des visiocasques et des projecteurs stéréoscopiques. En outre, elles sont applicables aux contenus d'images stéréoscopiques destinés à être présentés sur les écrans stéréoscopiques mentionnés ci-dessus, ainsi qu'aux présentations stéréoscopiques réalisées par les combinaisons de ces images et de ces affichages.

Ergonomija medsebojnega vpliva človek-sistem - 392. del: Ergonomska priporočila za zmanjšanje vizualne utrujenosti zaradi gledanja stereoskopskih slik (ISO 9241-392:2015)

ISO 9241-392:2015 vzpostavlja priporočila za zmanjšanje morebitnega vizualnega neugodja ali utrujenosti zaradi gledanja stereoskopskih slik pod določenimi pogoji gledanja. Do vizualne utrujenosti ali neugodja lahko pride zaradi stereoskopskega optičnega dražljaja pri gledanju različnih binokularno predstavljenih slik.
ISO 9241-392:2015 se uporablja tudi za končne proizvode stereoskopskih predstavitev, ki so odvisni od vsebine stereoskopske slike in stereoskopskih prikazovalnikov pri gledanju pod ustreznimi določenimi pogoji. Priporočila so zato namenjena osebam, odgovornim za oblikovanje, razvoj in posredovanje vsebine stereoskopskih slik ter stereoskopskih prikazovalnikov.
OPOMBA 1: Za ustrezne pogoje gledanja glej dodatek B.
Priporočila v tem delu standarda ISO 9241 se uporabljajo za stereoskopske prikazovalnike, kot so prikazovalniki z očali in samostereoskopski prikazovalniki z dvojnim pogledom, stereoskopski naglavni prikazovalniki in stereoskopski projektorji. Poleg tega se uporabljajo za vsebino stereoskopskih slik, namenjeno za predstavitev z zgoraj omenjenimi stereoskopskimi prikazovalniki, in stereoskopske predstavitve, upodobljene s kombinacijo teh slik in prikazovalnikov.
OPOMBA 2: Dodatek C podaja številska merila kot informativno referenco.
OPOMBA 3: V primeru potrebnih zahtev in priporočil, specifičnih za posamezno vrsto vsebine stereoskopskih slik ali stereoskopskega prikazovalnika, je treba vzpostaviti druga navodila ob sklicevanju na ta del standarda ISO 9241.
OPOMBA 4: Standarde za oddajanje običajno pripravi Mednarodna zveza za telekomunikacije.
OPOMBA 5: ISO 9241 303:2011, dodatek E podaja smernice za virtualne prikazovalnike, ki so namenjeni za uporabo kot stereoskopski naglavni prikazovalniki.

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
