6、 Benutzungsschnittstellen. ISO 9241 was originally developed as a seventeen-part International Standard on the ergonomics require-ments for office work with visual display terminals. As part of the standards review process, a major restructuring of ISO 9241 was agreed to broaden its scope, to incorp
7、orate other relevant standards and to make it more usable. The general title of the revised ISO 9241, “Ergonomics of human-system interaction”, reflects these changes and aligns the standard with the overall title and scope of Technical Committee ISO/ TC 159, Subcommittee SC 4. The revised multipart
8、 standard is structured as series of standards numbered in the “hundreds”: the 100 series deals with software interfaces, the 200 series with human centred design, the 300 series with visual displays, the 400 series with physical input devices, and so on. The DIN Standards corresponding to the Inter
9、national Standard referred to in this document are as follows: ISO 9241-12 DIN EN ISO 9241-12 ISO 9241-16 DIN EN ISO 9241-16 ISO 9241-171 DIN EN ISO 9241-171 Amendments This standard differs from DIN EN ISO 9241-17:2000-04 as follows: a) the standard has been brought in line with the state of the ar

29、ification. “Ergonomics”4DIN EN ISO 9241-143:2012-06 EN ISO 9241-143 (E) Introduction 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
30、various circumstances, including filling forms, such as income tax forms, registration (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
31、transactions, specifying the application options and parameters (complex data 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
32、complex data entry that involves multiple data records. Forms are often based 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 fr
33、om the system. This part of ISO 9241 is aimed at a) user-interface designers , 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 e
34、nsuring products meeting its requirements and recommendations, e) the designers 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 t
35、hese are conditional with respect to whether they are relevant in terms of context 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
36、of the standards requirements and recommendations that are applicable. Likewise, 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 92
37、41 be applied, only those that are relevant. Annex B provides an example of a procedure for evaluating the applicability of, and conformance with, the requirements and recommendations. N1) National footnote: The terms used in this standard, e.g. designer, evaluator, buyer, user etc. apply equally to
38、 women and men. For reasons of simplification and better legibility, the masculine form has been used throughout the document. N1)5DIN EN ISO 9241-143:2012-06 EN ISO 9241-143 (E) The application of this part of ISO 9241 is expected to improve the overall quality of the form, but this International S
39、tandard (like any other standard) will not guarantee the quality of the interface. 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. ISO 9241-110 describes dialogue principles that are rel
40、evant for the design 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-off
41、s on other considerations as well. 6DIN EN ISO 9241-143:2012-06 EN ISO 9241-143 (E) Ergonomics 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 entries for, o
42、r 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 lists. This part
43、 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 entri
44、es (e.g. list boxes) and pertains to dialogue boxes which utilize form techniques. Guidance is provided on the selection and design of those user-interface elements relevant to forms. While lists used to enter forms data are covered in this part of ISO 9241, menus which are similar to lists are outs
45、ide its scope but are covered in ISO 9241-14. Neither is this part of ISO 9241 applicable to the hardware aspects of forms. NOTE Some of the requirements and recommendations in this part of ISO 9241 are based on Western Language conventions. For other languages, particular requirements or recommenda
46、tions might need to be modified to fit the readability and/or text input considerations inherent in these languages. The requirements and recommendations in this part of ISO 9241 are applicable throughout the development process for example, as guidance for designers during design, as a basis for he
47、uristic evaluation, as guidance for usability testing and in the procurement process. 2 Normative references The following referenced documents are indispensable for the application of this document.
