Ergonomics of human-system interaction - Part 420: Selection of physical input devices (ISO 9241-420:2011)
This part of ISO 9241 applies to input devices for interactive systems. It provides guidance for selecting input devices based on ergonomic factors for the following input devices: keyboards, mouses, pucks, joysticks, trackballs, trackpads, tablets and overlays, touch sensitive screens, styli, and light pens.
This part of ISO 9241 gives guidance for selecting these devices so that the limitations and capabilities of users and the specific tasks and the specific context of use are considered.
The target users of this part of the standard are user organizations and systems integrators who tailor systems for a given context of use.
This part of ISO 9241 specifies methods for selecting a device or a combination of devices for the task at hand. It may also be used for evaluating the acceptability of trade-offs under the existing conditions.
This part of ISO 9241 does not specify design requirements or recommendations for devices.

Ergonomie de l'interaction homme-système - Partie 420: Sélection des dispositifs d'entrée physiques (ISO 9241-420:2011)
L'ISO 9241-420:2011 donne des indications pour sélectionner des dispositifs d'entrée pour systèmes interactifs, en fonction de facteurs ergonomiques, prenant en compte les capacités et les limites des utilisateurs ainsi que les tâches et le contexte spécifiques d'utilisation. Elle spécifie des méthodes de sélection d'un dispositif ou d'une combinaison de dispositifs axés sur la tâche à accomplir. Elle peut également servir pour évaluer l'acceptabilité de compromis dans les conditions existantes.
Les utilisateurs auxquels l'ISO 9241-420:2011 s'adresse sont les organismes utilisateurs et les intégrateurs de systèmes qui personnalisent ces systèmes en fonction d'un contexte d'utilisation donné.
Elle est applicable aux dispositifs d'entrée suivants: claviers, souris, souris optiques, manettes, boules roulantes, blocs à effleurement, tablettes et barres graphiques, écrans tactiles, stylets et photostyles. Elle ne spécifie aucune exigence ou recommandation de conception pour ces dispositifs.
Ergonomija medsebojnega vpliva človek-sistem - 420. del: Izbira naprav za fizični vnos podatkov (ISO 9241-420:2011)
Ta del ISO 9241 velja za naprave za vnos podatkov za interaktivne sisteme. Zagotavlja smernice za izbor naprav za vnos podatkov, zasnovanih na ergonomskih dejavnikih za naslednje naprave za vnos podatkov: tipkovnice, miške, ploščki, igralne palice, sledilne kroglice, table in prosojnice, na dotik občutljivi zasloni, gramofonske igle in svetlobna pisala.
Ta del ISO 9241 podaja smernice za izbor teh naprav, tako da se upoštevajo omejitve in zmogljivost uporabnikov pri določenih nalogah in v določenem okviru uporabe.
Ciljni uporabniki tega dela standarda so organizacije uporabnikov in sistemskih združevalcev, ki krojijo sistem za naveden okvir uporabe.
Ta del ISO 9241 določa metode za izbor naprave ali kombinacije naprav za podano nalogo. Prav tako se lahko uporabi za ocenjevanje sprejemljivosti kompromisov pod obstoječimi pogoji.
Ta del ISO 9241 ne določa zahtev pri načrtovanju ali priporočil za naprave.
