3.1

accessibility

extent to which products, systems, services, environments and facilities can be used by people from a population with the widest range of user needs, characteristics and capabilities to achieve identified goals in identified contexts of use

Note 1 to entry: Context of use includes direct use or use supported by assistive technologies.

3.2

assistive technology

AT

hardware or software added to, or incorporated within, a system that increases accessibility for an individual

[SOURCE: ISO 9241-171:2008, 3.5]

3.3

tactile

appertaining to touch

[SOURCE: ISO 9241-910:2011, 2.5]

3.4

haptic

appertaining to haptics (3.5)

Note 1 to entry: While there is no difference between haptic and tactile (3.3) in most dictionary definitions, in the area of haptics, researchers and developers use haptic to include all haptic sensations, while tactile is limited to mechanical stimulation of the skin. In ISO 9241, the word haptic covers all touch sensations and tactile is used in a more specific manner. Also, both terms can be used together to assist in searches.

3.5

haptics

sensory and/or motor activity based in the skin, muscles, joints and tendons

Note 1 to entry: Haptics consists of two parts: touch and kinaesthesis.

3.6

force feedback

force presented to and detected by a user

Note 1 to entry: Although this does not necessarily involve feedback, the term “force feedback” is commonly used in this context.

3.7

gesture

movement or posture, of the whole body or parts of the body

[SOURCE: ISO/IEC 30113-1:2015, 3.1]

3.8

interactive system

combination of hardware and/or software and/or services and/or people that users interact with in order to achieve specific goals

Note 1 to entry: This includes, where appropriate, packaging, user documentation, on-line and human help, support, and training.

[SOURCE: ISO 9241-11:2018, 3.1.5]

3.9

tactile cursor

tactile indication of where the user interaction via input device (e.g. keyboard or equivalent) occurs

3.10

sensory overload

user’s experience where sensory experiences from the environment are too great for the individual’s nervous system to successfully process or make meaning from

3.11

personal computer

microcomputer primarily intended for stand-alone use by an individual

[SOURCE: ISO/IEC 29136:2012, 3.5]

3.12

reach envelope

<tactile/haptic> three-dimensional space in which a person can reach an interface without discomfort with respect to a specified user position

Note 1 to entry: Different users can use different body parts such as the arm, leg or head to reach for an object while sitting or standing.

Note 2 to entry: Users can augment their reach envelope using different assistive technologies, prosthetics or tools.
