The work of preparing International Standards is normally ca
21、rried 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
22、. 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 Intern
23、ational 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. Attention is drawn to the possibility that some of the
24、 elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

Generally speaking, an input device is a sensor that can detect changes in user behaviour (gest
35、ures, moving fingers, etc.) and transform them into signals to be interpreted by the interactive system. Input devices are utilized for the sole purpose they have been designed for, e.g. a keyboard for entering character codes. Under certain circumstances they may be used also for other purposes. Ho
36、wever, in this case, generally their efficiency and/or effectiveness is restricted to a certain degree (e.g. keyboard for pointing). An input device can also be used in combination with others if needed to enhance the capabilities of users. Utilizing a keyboard and a mouse for drawing straight lines
37、 is an example of the latter. Whether or not an input device or a combination of input devices is acceptable from an ergonomic point of view is to be determined following the rationale of the usability concept. This concept postulates that an entity has no inherent usability, but one in a specified
38、context of use, for specified goals and specified users. A product may be designed for an intended user population and for a restricted context of use, e.g. for children in moderately conditioned indoor spaces. Specifying goals for using a device needs additional considerations, however. Goals that
39、the users of input devices need to achieve may be defined as high-level tasks such as “word processing” or “multimedia”. A definition in this level, however, may be too abstract to design, test or select a device on the basis of usability. For this reason, this standard specifies “task primitives” s
40、uch as “pointing”, “dragging” or “code input”. Design and selection equipment requires a fit to be achieved between a range of task requirements and the needs of users. The concept of fit as defined in ISO 9241-5:1998 concerns the extent to which equipment (visual display units, input devices, etc.)
41、 can accommodate individual users needs. Good fit is needed for the intended user population, including users with special needs, e.g. people with disabilities, if the use of a certain device is not limited to a specified user population and task. Since a variety of input devices exists that may ena
42、ble a user to achieve the same usability for the same task by creating input through different bodily abilities (e.g. hand, foot, speech or eye control) the required fit can be achieved by utilizing any device that offers the required level of usability. Depending on the character of the special nee
43、ds, a combination of different devices may be necessary, e.g. a foot- and an eye-controlled input device instead of a mouse for a person who cannot use his or her hands for whatever reason. This part of ISO 9241 specifies generic ergonomic principles valid for the design and use of input devices. To
44、 be able to formulate recommendations for groups or types of input devices, a set of typologies is introduced, based on aspects according to which possible designs can be differentiated: physical variables carrying the information (relative/absolute position, force, velocity, acceleration, etc.); bo
45、dily part used for operation; dimensionality of control (degrees of freedom); multiplicity of control (number of parallel control variables); control modality (discrete/continuous); control monitoring (one-shot or continuous time, holds last value or returns to nominal value, sequential or skip-out
46、the continuum output, etc.); control distance function (monotonic, non-monotonic, uni/bipolar, etc.); EN ISO 9241-400:2007BS EN ISO 9241-400:2007EN ISO 9241-400:2007vii mapping, straightforwardness; psychological nature of control (causality, exploratory or goal-oriented control). It also specifies
47、properties relevant for the usability of input devices and typologies in consideration of different aspects (e.g. degrees of freedom, property sensed etc.). Guidance on the application of these principles on product design is given in ISO 9241-410. The ergonomic guidance for the design of products i
48、s given without including aspects related to a particular context (e.g. using keyboards at CAD workstations). Selecting the intended context of use is part of the design process and not the subject of this part of ISO 9241. ISO 9241-4112)is to specify methods for determining conformance through obse
49、rvation, performance and by measurement of the physical attributes of the various devices. NOTE This part of ISO 9421 will be supported by the following methods (ISO 9241-411): usability test for text and data input using stationary keyboards (currently given in ISO 9241-4); generic usability test for keyboards for non-touch typing tasks; input device selection, usability testing and analysis (currently given in ISO 9241-9); testing of efficiency and effectiveness of
