This document: - 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 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 is not applicable to standard input devices such as keyboards, mice or track balls. NOTE The ISO 9241-400 subseries covers standard input devices, and ISO 9241-411 applies to the evaluation of input devices such as keyboards and mice. ISO 9241-940 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).
