ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.

Introduction
Tactile and haptic interactions are becoming increasingly important as candidate interaction modalities in
computer systems such as special-purpose computing environments (e.g. simulation) and assistive
technologies.
While considerable research exists, it involves a wide diversity of terms, meanings of terms, viewpoints,
software and hardware objects, attributes and interactions. This diversity can lead to serious ergonomic
difficulties for both developers and users of tactile/haptic interactions.
This part of ISO 9241 provides a common set of terms, definitions and descriptions for the various concepts
central to the design and use of tactile/haptic interactions. It includes basic guidance (including references to
related standards) in the design of tactile/haptic interactions. It also provides an overview of the range of
tactile/haptic applications, objects, attributes and interactions.

Ergonomics of human-system interaction —
Part 910:
Framework for tactile and haptic interaction
1 Scope
This part of ISO 9241 provides a framework for understanding and communicating various aspects of
tactile/haptic interaction. It defines terms, describes structures and models, and gives explanations related to
the other parts of the ISO 9241 “900” subseries. It also provides guidance on how various forms of interaction
can be applied to a variety of user tasks.
It is applicable to all types of interactive systems making use of tactile/haptic devices and interactions.
It does not address purely kinaesthetic interactions, such as gestures, although it might be useful for
understanding such interactions.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
haptics, noun
sensory and/or motor activity based in the skin, muscles, joints and tendons
NOTE Haptics consists of two parts: touch and kinaesthesis.
2.2
haptic, adj
appertaining to haptics
NOTE While there is no difference between haptic and tactile 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.
2.3
touch
sense based on receptors in the skin
NOTE Cutaneous receptors are used for the perception of touch.
2.4
cutaneous
belonging to the skin
NOTE Cutaneous receptors respond to mechanical stimulation and temperature changes.

2.6
vibrotactile
vibration-based stimulation of the skin
EXAMPLE A cellular phone uses vibrotactile stimulation to alert the user.
2.7
kinaesthesis, noun
sense and motor activity based in the muscles, joints and tendons
NOTE 1 Kinaesthesis includes both input and output.
NOTE 2 Receptors in the muscles, joints and tendons are used for the perception of kinaesthesis.
NOTE 3 Muscles, tendons and joints are used for motor activity.
2.8
kinaesthetic, adj
appertaining to kinaesthesis
NOTE 1 Types of kinaesthetic sensation arise from force, movement, position, displacement and joint angle.
NOTE 2 Types of kinaesthetic actions include movement, exertion of force and torque, and achievement of position,
displacement and joint angle.
NOTE 3 Proprioception refers to the sense of one's own body position and movement. This term is often used
interchangeably with kinaesthesis, although the latter is concerned more with motion. The sense of balance, for example,
might fall more under proprioception than kinaesthesis.
2.9
force feedback
force presented to and detected by a user
NOTE Although this does not necessarily involve feedback, the term “force feedback” is commonly used in this
context.
2.10
perceptual illusion
perception that does not correspond to a physical measurement of the stimulus source
2.11
sensory adaptation
change over time in the responsiveness of the sensory system to a constant stimulus
2.12

the target
2.13
(tactile/haptic) temporal masking
effect that occurs when a distracter stimulus, which is presented immediately preceding or following a target
stimulus, degrades the perception of the target

3 Introduction to haptics
The science of haptics and the creation of tactile/haptic devices depend on knowledge of the human body,
especially on its capability to sense both touch to the skin and kinaesthetic activity in the limbs and body joints.
Figure 1 shows the relationship between the components that make up the field of haptics. The field is divided
between the study of touch and the study of kinaesthesis.

Figure 1 — The components of haptics
“Touch” includes such diverse stimuli as mechanical, thermal, chemical and electrical stimulation to the skin.
Specific nerves and sensing organs in the skin respond to these stimuli with different spatial and temporal
resolutions.
The kinaesthetic sense can be matched by kinaesthetic activity by which a user exerts force or torque on an
object external to the active body part. With the combination of kinaesthetic sensing and kinaesthetic activity,
the user can detect the force and torque with which the body resists the force and torque of a tactile/haptic
device. Likewise, by imposing a measured force and torque on an object, the user can determine macro
properties such as its inertia.
Kinaesthesis is thereby bi-directional, both sensing the environment and actively manipulating it in a two-way
exchange of information and action.
NOTE 1 Active touch involves kinaesthesis, passive touch does not. Active and passive touch are often very useful
concepts by which to distinguish interactions. In interactions, it is not always possible to identify the two concepts with
particular devices. Depending on the task, one form of touch might be superior to another.
NOTE 2 Interaction with tactile/haptic devices might use different combinations of these haptic components at multiple
points of contact.
NOTE 3 See Annex C for the details of the physiology of human haptics.

4 Human haptic exploration
4.1 Importance of the haptic sense
Haptics is of great importance for human life, much more so than is generally recognized. For instance, when
you are searching for an object in your pocket or bag without the help of vision, haptics is engaged. When you
identify the object you wanted, grasp it with suitable force and take it out, your actions are based on haptics.
This sense can identify common objects quite efficiently, with near perfect discrimination within a few seconds,
especially when the observer has some expectation about the options.
By palpating the surface of a body, a physician can obtain information about the conditions of organs under
the skin and fat layers, conditions that cannot be perceived visually.
The haptic sense can also allow remote touching, as when a distant object is probed with a tool. For example,
a visually impaired person may use a cane to perceive the properties of the ground at the tip of the cane.
The hands, in particular, have had an enormous importance in the biological and cultural development of
human beings in their contact with the environment. They are at the same time useful for both perception and
action in a continuous interaction with the environment. A hand has an impressive ability to adapt to many
different kinds of manipulation tasks, from very small ones requiring high precision to large ones where large
forces are needed. The actions are at all times guided by haptic feedback.
However, haptics within computer applications is new compared to visual and auditory interactions and is still
relatively limited. Present-day tactile/haptic devices still need much development before they can fully utilize
the capacity of the haptic sense.
Touch is also often used to confirm information we gain about the reality of the world.
4.2 Haptics and vision
4.2.1 Similarities and differences between haptics and vision
Haptics has many properties in common with vision. It can be used to locate objects in relation to the observer
in near space (but only within arm's reach unless a tool is used), to find edges separating surfaces and to
perceive the size and form of objects (that are not too large to be explored by a person). In perceiving texture,
haptics not only matches vision but is, in many conditions, superior to it.
