22、ies). 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
23、 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,
24、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 cast
25、ing a vote. Attention is drawn to the possibility that some of the 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. ISO 9241-143 was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC

36、uction This part of ISO 9241 is concerned with the ergonomic design of forms. Forms, including dialogue boxes, are appropriate for data entry tasks requiring input or modification of multiple data items. Forms are used in various circumstances, including filling forms, such as income tax forms, regi
37、stration (school, motor vehicle), and service order completion, entering information received over the telephone, interactively populating data in an application, such as database updates, consumer profiles and e-commerce transactions, specifying the application options and parameters (complex data
38、retrieval requests, personalisation, system configurations settings), and responding to a mediate request for system information (e.g. using a dialogue box). Forms can vary in content and complexity from a simple field to complex data entry that involves multiple data records. Forms are often based
39、on a visual spatial metaphor but can be implemented in other modalities (e.g. voice user interfaces over the telephone). Form users fill-in, select entries for, modify fields and/or use, the form to retrieve information from the system. This part of ISO 9241 is aimed at a) user-interface designers,
40、who will apply it during the development process, b) the designers of printed forms which serve as source documents, c) buyers, who will reference it during the product procurement process, d) evaluators responsible for ensuring products meeting its requirements and recommendations, e) the designers
41、 of development tools to be used by interface designers, and f) end users, who will gain from the potential benefits it provides. This part of ISO 9241 provides requirements and recommendations concerning forms. Some of these are conditional with respect to whether they are relevant in terms of cont
42、ext of use variables such as particular kinds of users, tasks, environments or technology. Designers using this part of ISO 9241 ought to be able to determine whether they are developing an interface that will meet those of the standards requirements and recommendations that are applicable. Likewise
43、, buyers and evaluators ought to have a means of determining how a product matches the applicable requirements and recommendations. It is not intended that every requirement and recommendation given in this part of ISO 9241 be applied, only those that are relevant. Annex B provides an example of a p
44、rocedure for evaluating the applicability of, and conformance with, the requirements and recommendations. The application of this part of ISO 9241 is expected to improve the overall quality of the form, but this International Standard (like any other standard) will not guarantee the quality of the i
45、nterface. Quality depends on specific usability criteria as set by the user, buyer or other form consumer, which may include specifications based on this part of ISO 9241. BS EN ISO 9241-143:2012ISO 9241-143:2012(E) viii ISO 2012ISO 9241-110 describes dialogue principles that are relevant for the de
46、sign of forms. The principles provide the designer and evaluator with additional information concerning the ergonomic rationale for the various recommendations given in this part of ISO 9241 and, therefore, assist in making trade-offs. However, it is often necessary to base trade-offs on other consi
47、derations as well. BS EN ISO 9241-143:2012INTERNATIONAL STANDARD ISO 9241-143:2012(E) ISO 2012 1Ergonomics of human-system interaction Part 143: Forms 1 Scope This part of ISO 9241 provides requirements and recommendations for the design and evaluation of forms in which the user fills-in, selects en
48、tries for, or modifies labelled fields on, a “form” or dialogue box presented by the system. Often the system then creates or updates the data associated with the form. Form-based entries typically are in the form of typed input (abbreviations, or full names) or selections from available option list
49、s. This part of ISO 9241 is applicable to forms regardless of the modality in which they are rendered (visual, spatial, vocal). However, much of the guidance is based on a model of visual and spatial relationship. In addition, this part of ISO 9241 specifies the use of non-text methods for providing forms entries (e.g. list boxes) and pertains to dialogue boxes which utilize form techniques. Guidance is provided on the selection and design of those user-interfac
