Ergonomics of human-system interaction - Part 920: Tactile and haptic interactions (ISO 9241-920:2024)

This part of ISO 9241 gives recommendations for tactile/haptic hardware and software interactions. It provides guidance on the design and selection of hardware, software, and combinations of hardware and software interactions, including
•   the design/use of tactile/haptic inputs, outputs, and/or combinations of inputs and outputs, with general guidance on their design/use as well as on designing/using combinations of tactile and haptic interactions for use in combination with other modalities or as the exclusive mode of interaction,
•   the tactile/haptic encoding of information, including textual data, graphical data and controls,
•   the design of tactile/haptic objects,
•   the layout of tactile/haptic space, and
•   interaction techniques.
For guidance and recommendations on the accessibility of tactile/haptic interactions, including information on the use of braille, see ISO 9241-971. It does not provide recommendations specific to braille but can apply to interactions that make use of braille.
The recommendations given in this part of ISO 9241 are applicable to a variety of tactile/haptic devices, representing the real world or virtual or mixed realities (e.g. exoskeletons, wearables, force feedback devices, touchables, tangibles) and stimulation types (e.g. acoustic radiation pressure, electrical muscle stimulation) and they can also be found in virtual and augmented environments.
This document does not include guidance on the role of walking in virtual or mixed realities for tactile/haptic interaction.
NOTE   It is recognized that some interactive scenarios might be constrained by the limitation that a real workspace is to be modelled in a virtual environment. Objects can be in suboptimal positions or conditions for haptic interaction by virtue of the situation being modelled.
This document provides general information about how various forms of interaction can be applied to various user tasks. The use of gestures (e.g. multitouch) can be found in ISO 9241-960. Information on gesture-based interfaces can be found in the multipart standard ISO/IEC 30113. Information on contactless gestures can be found in ISO TS 9241-430.

Ergonomie der Mensch-System-Interaktion - Teil 920: Taktile und haptische Interaktionen (ISO 9241-920:2024)

Dieses Dokument spezifiziert Anforderungen an und Empfehlungen für taktile/haptische Hardware- und Software-Interaktionen. Er bietet eine Anleitung zur Gestaltung und Auswahl von Hardware, Software und Kombinationen aus Hardware- und Software-Interaktionen einschließlich
   Gestaltung oder Gebrauch von taktilen/haptischen Eingaben, Ausgaben und/oder Kombinationen von Eingaben und Ausgaben, mit einer allgemeinen Anleitung zu deren Gestaltung oder Gebrauch sowie zu taktilen und haptischen Interaktionen zur Gestaltung und zum Gebrauch in Kombination mit anderen Modalitäten oder als die ausschließliche Interaktionsmodalität;
   taktiler/haptischer Informationskodierung einschließlich Textdaten, Graphikdaten und Steuerelementen;
   die Gestaltung taktiler/haptischer Objekte;
   Anordnung des taktilen/haptischen Raums;
   Interaktionstechniken.
Die Empfehlungen in diesem Dokument sind für eine breite Palette von taktilen/haptischen Geräten, die die reale Welt, virtuelle Realitäten (VR, en: Virtual Reality) oder vermischte Realitäten (MR, en: Mixed Reality) (z. B. Exoskelette, Wearables, Geräte zur Kraftrückmeldung, Touchables, Tangibles) abbilden, und Stimulationsarten (z. B. Schallstrahlungsdruck, elektrische Muskelstimulation) anwendbar. Sie können auch in Virtual-Reality- und Augmented-Reality-Umgebungen Anwendung finden.
Dieses Dokument enthält allgemeine Informationen dazu, wie verschiedene taktile/haptische Interaktionsformen für verschiedene Benutzeraufgaben angewendet werden können.
Dieses Dokument umfasst keine Leitlinien zur Rolle des Sich-Bewegens in virtuellen oder gemischten Realitäten bei taktilen/haptischen Interaktionen.
ANMERKUNG   Es ist bekannt, dass einige interaktive Szenarien durch die Einschränkungen begrenzt sein können, die durch die Modellierung eines tatsächlichen Arbeitsplatzes in einer virtuellen Umgebung auferlegt werden. Objekte können sich aufgrund der zu modellierenden Situation an nicht optimalen Positionen oder in nicht optimalen Bedingungen für die taktile/haptische Interaktion befinden.

Ergonomie de l'interaction homme-système - Partie 920: Interactions tactiles et haptiques (ISO 9241-920:2024)

Le présent document donne des exigences et des recommandations ergonomiques relatives aux interactions tactiles/haptiques des matériels et des logiciels. Elle fournit des lignes directrices relatives à la conception et à la sélection des interactions des matériels et des logiciels ainsi que de leurs combinaisons, y compris:
—     la conception ou l'utilisation des entrées et sorties tactiles et haptiques et/ou des combinaisons d'entrées et sorties, avec des lignes directrices générales relatives à leur conception ou leur utilisation ainsi que des lignes directrices relatives à la conception ou à l’utilisation des combinaisons d'interactions tactiles et haptiques destinées à l'utilisation en combinaison avec d'autres modalités ou en tant que mode exclusif d'interaction;
—     le codage tactile/haptique d'informations, y compris les données textuelles, les données graphiques et les commandes;
—     la conception d'objets tactiles/haptiques;
—     l'aménagement de l'espace tactile/haptique;
—     les techniques d'interaction.
Les recommandations énoncées dans le présent document sont applicables à divers dispositifs tactiles/haptiques, représentant le monde réel ou des réalités virtuelles ou mixtes (par exemple, exosquelettes, appareils portables, dispositifs à retour d'effort, surfaces tactiles, tangibles) et divers types de stimulation (par exemple, pression de rayonnement acoustique, stimulation musculaire électrique) et pouvant également se trouver dans des environnements virtuels et augmentés.
Le présent document fournit des informations générales sur la manière dont diverses formes d'interaction tactile/haptique peuvent être appliquées à diverses tâches de l'utilisateur.
Le présent document ne comporte pas de recommandations concernant le rôle de la marche en réalité virtuelle ou mixte pour l'interaction tactile/haptique.
NOTE            Il est admis que certains scénarios interactifs peuvent être limités par le besoin de modéliser un espace de travail en un environnement virtuel. Les objets peuvent se trouver dans des positions ou conditions sous-optimales pour l'interaction tactile/haptique en raison de la situation à modéliser.
