EN ISO 9241-14:1999 BSI 11-2000 Introduction International Standard ISO 9241 deals with several aspects of the use of VDTs. Currently, the individual parts can be grouped in the following categori

12、es: ISO 9241-1, Introduction. ISO 9241-2, Guidance on task requirements. ISO 9241-5 and ISO 9241-6, Workstation and environment. ISO 9241-3, ISO 9241-4, ISO 9241-7, ISO 9241-8 and ISO 9241-9, Ergonomics pertaining to hardware. ISO 9241-10 through ISO 9241-17, Ergonomics pertaining to software interf

13、aces. ISO 9241-14 is concerned with the ergonomic design of menu dialogues. In menu dialogues, the dialogue system presents one or more groups of options to the user, the user chooses one or more options, and the computer executes the desired process denoted by the option(s). ISO 9241-14 serves the

14、following types of user: ISO 9241-14 consists of a number of recommendations, some of which are conditional, concerning menus. Conditional recommendations are recommendations that should be met only within the specific context for which they are relevant (e.g., particular kinds of users, tasks, envi

15、ronments, technology). These recommendations were developed primarily by reviewing the existing relevant literature and empirical evidence, then generalizing and formulating this work into recommendations. The source of the evidence for the individual recommendations can be found in Annex C. The app

16、lication of ISO 9241-14 is expected to improve the overall quality of the menus, but this standard (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 menu dialogue consumer which may include spe

17、cifications based on this standard. It should be noted that ISO 9241-10 describes dialogue principles that are relevant for the design of menu dialogues. These principles should provide the designer and evaluator with additional information concerning the ergonomic rationale for the various recommen

18、dations in ISO 9241-14 and, therefore, assist in making tradeoffs. However, it may be necessary to base tradeoffs on other considerations as well. iv the user interface designer, who will apply ISO 9241-14 during the development process; the buyer, who will reference ISO 9241-14 during the product p

19、rocurement process; evaluators responsible for ensuring products meet the recommendations in ISO 9241-14, designers of user interface development tools to be used by interface designers; end users who will gain from the potential benefits provided by the standard. Differences in the relative importa

20、nce of the task, user, environment, and technology in the design process are inevitable and have led to the if then structure of many of the conditional recommendations. For example, If rapid search time is important, then place as many options and levels as possible on a single menu panel. This met

21、hod provides practical, usable and unambiguous guidance during user interface design. Designers and evaluators using ISO 9241-14 need to know that they are developing an interface that will meet the recommendations provided in this part. Likewise, the buyer needs a means to determine how a product m

22、atches the recommendations in ISO 9241-14. The elements can be tailored due to the if then structure in ISO 9241-14. Additionally, it is not the intent of ISO 9241-14 that every recommendation should be applied, only those that are relevant. 1 Scope This part of ISO 9241 provides conditional recomme

23、ndations for menus used in user-computer dialogues to accomplish typical office tasks. The recommendations cover menus presented by various techniques including windowing, panels, buttons, fields, etc. These recommendations can be utilized throughout the design process (e.g. as guidance for designer

24、s during design, as a basis for heuristic evaluation, as guidance for usability testing). Interface design depends upon the task, the user, the environment, and the available technology. Consequently, ISO 9241-14 cannot be applied without a knowledge of the design and use context of the interface an

25、d it is not intended to be used as a prescriptive set of rules to be applied in their entirety. Rather, it assumes that the designer has proper information available concerning task and user requirements and understands the use of available technology (this may require consultation with a qualified

26、ergonomics professional as well as empirical testing with real users). Although this is an International Standard, some of the conditional recommendations are based on Latin-based language usage and may not apply, or may need to be modified, for use with a different language. For example, in right-t

27、o-left languages those conditional recommendations oriented towards left-to-right reading may need to be modified and adapted. In applying those conditional recommendations that assume a specific language base (e.g. alphabetic ordering of menu options, compound titles), care should be taken concerni

28、ng the intent of the standard when translation is required to a different language. The recommendations relate to the three major design components of user interfaces, i.e. dialogue, input, and output. Dialogue design determines the way in which a user is guided by the system to make inputs and infl

29、uences the amount of control the user has over the dialogue. The dialogue should be designed to support the user in his/her actual work without the user being bothered by additional work caused by system peculiarities. Menu dialogue design is covered in this part of ISO 9241 in terms of designing th

30、e menu structure, providing facilities for menu navigation and defining the selection methods for menu options. Input design is concerned with how users input information into the system using various input devices. Menu options can be selected by means of one or more input devices such as an alphan

31、umeric keyboard, function keys, cursor keys, pointing devices and voice (other devices are not excluded) depending on the task at hand and dialogue requirements, as well as on individual preferences. ISO 9241-14 provides conditional recommendations for the use of each of the input devices listed abo

32、ve. Output design is concerned with how data should be presented consistently and perceptibly distinct on the display. ISO 9241-14 provides conditional recommendations for the placement of options and option groups, the structure and syntax for textual, graphic and auditory options and presentation

33、techniques to indicate option accessibility and discrimination. Providing users with the capability to alter the interface to suit their own needs has become a popular approach to software interface design. This is often a desirable feature of the interface. However, providing users with customizati

34、on capabilities is not an acceptable substitute for ergonomically designed initial menus (i.e. default menus). It should be noted that customization of the menus may result in deviations from ISO 924114. Therefore, customization options also should be evaluated with respect to the recommendations in ISO 924114. 1 EN ISO 9241-14:2000
