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

This document specifies requirements and 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 or use of tactile/haptic inputs, outputs and/or combinations of inputs and outputs, with general guidance on their design or use as well as on designing or 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;
—     interaction techniques.
The recommendations given in this document 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 provides general information about how various forms of tactile/haptic interaction can be applied to various user tasks.
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 can 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 tactile/haptic interaction by virtue of the situation being modelled.

CEN ISO/TS 9241-430:2023(Main)
Ergonomics of human-system interaction - Part 430: Recommendations for the design of non-touch gestural input for the reduction of biomechanical stress (ISO/TS 9241-430:2021)
SIST-TS CEN ISO/TS 9241-430:2023

This document provides guidance on the design, selection and optimization of non-contacting hand and arm gestures for human-computer interaction. It addresses the assessment of usability and fatigue associated with different gesture set designs and provides recommendations for approaches to evaluating the design and selection of gestures. This document also provides guidance on the documentation of the process for selecting gesture sets.
This document applies to gestures expressed by humans. It does not consider the technology for detecting gestures or the system response when interpreting a gesture. Non-contacting hand gestures can be used for input in a variety of settings, including the workplace or in public settings and when using fixed screens, mobile, virtual reality, augmented reality or mixed-mode reality devices.
Some limitations of this document are:
—    The scope is limited to non-contacting gestures and does not include other forms of inputs. For example, combining gesture with speech, gaze or head position can reduce input error, but these combinations are not considered here.
—    The scope is limited to non-contacting arm, hand and finger gestures, either unilateral (one-handed) or bilateral (two-handed).
—    The scope assumes that all technological constraints are surmountable. Therefore, there is no consideration of technological limitations with interpreting ultra-rapid gestures, gestures performed by people of different skin tones or wearing different colours or patterns of clothing.
—    The scope is limited to UI-based command-and-control human computer interaction (HCI) tasks and does not include gaming scenarios, although the traversal of in-game menus and navigation of UI elements is within scope.
—    The scope does not include HCI tasks for which an obviously more optimal input method exists. For example, speech input is superior for inputting text than gesture input.
—    The scope includes virtual reality (VR), augmented reality (AR) and mixed reality (MR) and the use of head-mounted displays (HMDs).
—    The scope does not include the discoverability of gestures but does include the learnability and memorability of gestures. It is assumed that product documentation and tutorials will adequately educate end users about which gestures are possible. Therefore, assessing gesture discoverability is not a primary goal of the recommendations in this document.

Ergonomics of human-system interaction - Part 940: Evaluation of tactile and haptic interactions (ISO 9241-940:2017)
SIST EN ISO 9241-940:2022

ISO 9241-940:2017
-      describes the types of methods that can be used for the evaluation of haptic devices and of systems that include haptic devices,
-      specifies a procedure for the evaluation of haptic interactions by a usability walkthrough or usability test (see Annex J), and
-      provides guidance on the types of methods that are appropriate for the evaluation of specific attributes of haptic systems, cross-referenced to the guidance in the relevant clauses of other International Standards (see Annexes A, B, C, D, E, F and G).
It applies to the following types of interaction:
-      augmented reality - information overlaid on a real scene, e.g. vibrating belt indicating distance;
-      gesture control of a device or a virtual scenario;
-      unidirectional interaction such as a vibrating phone or a vibrating belt;
-      virtual environment - virtual space with which a user can interact with the aid of a haptic device.
ISO 9241-940:2017 applies to the following types of devices:
-      gesture sensor, e.g. video that discerns 3D hand movements, touch screens that sense 2D touches;
-      kinaesthetic haptic device, e.g. desktop haptic interface;
-      tactile display, e.g. vibrating phone.
ISO 9241-940:2017 is not applicable to standard input devices such as keyboards, mice or track balls.
NOTE       ISO 9241‑400 covers standard input devices, and ISO 9241‑411 applies to the evaluation of input devices such as keyboards and mice.
ISO 9241-940:2017 can be used to identify the types of methods and measures for
-      establishing benchmarks,
-      establishing requirements for haptic interaction,
-      identifying problems with haptic interaction (formative evaluation), and
-      use of the criteria to establish whether a haptic system meets requirements (summative evaluation).

CEN ISO/TS 9241-126:2022(Main)
Ergonomics of human-system interaction - Part 126: Guidance on the presentation of auditory information (ISO/TS 9241-126:2019)
SIST-TS CEN ISO/TS 9241-126:2022

This document provides guidance for the auditory presentation of information controlled by software, irrespective of the device. It includes specific properties such as the syntactic or semantic aspects of information, e.g. coding techniques, and gives provisions for the organization of information taking account of human perception and memory capabilities.
This document does not address the hardware issues of the transmission and the production of auditory information.
NOTE 1  Volume is dependent on hardware and thus cannot always be absolutely controlled by software. Environmental conditions can also affect the ability for sounds to be perceived, which can be beyond the ability of the software to take into account.
This document does not apply to auditory alarms, warnings or other safety-related uses of auditory information.
NOTE 2  Safety-related uses of auditory presentation of information are covered in various domain specific standards, such as ISO 7731:2003 which deals with auditory danger signals for public and work areas, and IEC 60601-1-8:2006 which provides very specific requirements for auditory alarms for medical devices.
While this document applies to the presentation of all non-safety-related information, it does not include application domain specific guidance (e.g., audio instructions for consumer products).
This document can be utilized throughout the design process (e.g. as specification and guidance for designers during design or as a basis for heuristic evaluation). Its provisions for the presentation of information depend on the auditory design approach, the task, the user, the environment and the single or multiple technologies that can be used for presenting the information. Consequently, this document cannot be applied without knowledge of the context of use. It is not intended to be used as a prescriptive set of rules to be applied in its entirety but rather assumes that the designer has proper information available concerning task and user requirements and understands the use of available technology.
This document does not address visual or tactile/haptic presentation of information or modality shifting for the presentation of auditory information in other modalities.
NOTE 3  ISO 9241-112 provides high-level ergonomic guidance that applies to all modalities.
