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).
