The work of preparing International Standards is normally carried out through ISO technical committees. Each member body

21、 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 Electrotec

22、hnical Commission (IEC) on all matters of electrotechnical standardization. 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 least75% of the member bodies casting a vote.

23、 International Standard ISO9241-15 was prepared by Technical Committee ISO/TC159, Ergonomics, Subcommittee 4, Ergonomics of human-system interaction. ISO 9241 consists of the following Parts, under the general title Ergonomic requirements for office work with visual display terminals (VDTs) Part 1:

24、General Introduction; Part 2: Guidance on task requirements; Part 3: Visual display requirements; Part 4: Keyboard requirements; Part 5: Workstation layout and postural requirements; Part 6: Environmental requirements; Part 7: Requirements for display with reflections; Part 8: Requirements for displ

Annex A and Annex B of this part of ISO9241 are for information only.iv blankENISO9241-15:1997 BSI 04-1999 1 Introduction ISO 9241 covers both the hardware and software ergonomic aspects of the use of visual display terminals. The description of the individual parts of ISO9241, thei

27、r interrelationships, and a description of the expected users of the parts is described in ISO9241-1. ISO 9241-15 is concerned with the ergonomic design of command dialogues. In command dialogues, users input, by recall, either complete or abbreviated command phrases as required by the command langu

28、age syntax, and the computer performs the actions associated with the commands and their parameters. ISO 9241-15 serves the following types of user of this part of ISO9241: a) The user-interface designer, who will apply ISO9241-15 during the development process. b) The buyer, who will reference ISO9

29、241-15 during the product procurement process. c) Evaluators responsible for ensuring that products meet the recommendations in ISO9241-15. d) Designers of user-interface development tools to be used by interface designers. e) End-users who will gain from the potential benefits provided by this part

30、 of ISO9241. The ultimate beneficiary of this part of ISO9241 will be the end-user at the VDT. It is the needs of these users that provide the ergonomic recommendations in ISO9241-15. Although it is unlikely that the end-user will read this part of ISO9241 or even know of its existence, its applicat

31、ion should provide user interfaces that are more usable, consistent and that enable greater productivity. In order to apply ISO 9241-15 within the overall context of the ergonomic requirements for human-system interaction, it is suggested that users be familiar with the following parts of9241: ISO 9

32、241-1, Ergonomic requirements for office work with visual display terminals (VDTs) Part 1: General introduction. ISO 9241-2, Ergonomic requirements for office work with visual display terminals (VDTs) Part 2: Guidance on task requirements. ISO 9241-10, Ergonomic requirements for office work with vis

33、ual display terminals (VDTs) Part 10: Dialogue principles. ISO 9241-13, Ergonomic requirements for office work with visual display terminals (VDTs) Part 13: User guidance. ISO 9241-15 consists of a number of recommendations, some of which are conditional, concerning command dialogues. Conditional re

34、commendations are recommendations which should be met within the specific context for which they are relevant (e.g. particular kinds of users, tasks, environments, technology). These recommendations were developed primarily by reviewing the existing relevant literature and empirical evidence, then g

35、eneralizing and formulating this work into recommendations for use by the interface designer and/or evaluator. Sources for the individual recommendations are listed in Annex B. Designers and evaluators using ISO9241-15 need to know that they are developing an interface that will meet the recommendat

36、ions provided therein. Likewise, the buyer needs a means to determine how a product matches the recommendations in ISO9241-15. The elements can be tailored due to the “if then” structure in ISO9241-15. Additionally, it is not the intent of ISO9241-15 that every recommendation should be applied, only

37、 those that are relevant. The application of this part of ISO9241 is expected to improve the overall quality of the command language, but ISO9241-15 (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

38、other command-dialogue consumer which may include specifications based on this part of ISO9241. It should be noted that ISO9241-10 describes dialogue principles that are relevant for the design of command dialogues. These principles should provide the designer and evaluator with additional informati

39、on concerning the ergonomic rationale for the various recommendations in ISO9241-15 and, therefore, assist in making tradeoffs. However, it may be necessary to base tradeoffs on other considerations as well. 1 Scope This part of ISO 9241 provides recommendations for command dialogues used to accompl

40、ish typical office tasks using visual display terminals (VDTs). Command dialogues are sequences of instructions provided by the user to the system which, when processed, result in associated system actions. Users input (from recall, rather than selecting from a menu) complete or abbreviated command

41、phrases (e.g. mnemonics, letters, function keys, hot keys in the order required by the command language syntax and the computer performs the activities initiated by the command(s) and their associated parameters.ENISO 9241-15:1997 2 BSI 04-1999 Interface design depends upon the task, the user, the e

42、nvironment, and the available technology. Consequently, ISO9241-15 cannot be applied without a knowledge of the design and use context of the interface and 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 in

43、formation available concerning task and user requirements and understands the use of available technology (this may require consultation with a qualified ergonomics professional as well as empirical testing with real users). ISO 9241-15 applies to the use of command dialogues, either in conjunction

44、with other dialogues (e.g.menus, direct manipulation) or as the primary dialogue technique (e.g.in the case of “dumb terminals” or where high speed is required in a particular application). In addition, this part of ISO9241 provides recommendations for those “key” commands (i.e. function keys and ho

45、t keys) which represent commands within a command dialogue. If the command functions are evident from the nature of their representation (e.g. pictorial icons) and invoking these functions does not require memory on the part of the user, this would not be considered a command dialogue according to I

46、SO9241-15. Commands can be accessed through other dialogue techniques (e.g.menu options, forms, direct manipulation). However, these methods do not require recall on the part of the user and will be excluded from this part of the standard and will be dealt with in other parts. It also should be note

47、d that ISO9241-15 does not provide guidance for dialogues which use “natural” language. 2 Definitions For the purposes of this part of ISO9241, the following definitions apply: 2.1 argument independent variable (including object) used in a command phrase to modify or direct the action of a command N

48、OTEArguments often include parameters. 2.2 command whole word, abbreviation, or string of words representing actions requested of the system 2.3 command dialogue; command language command set(s), phrases, structure and syntax associated with a specific interaction of a user with a computer system by

49、 means of commands 2.4 command dialogue structure logical structure of the command dialogue (and associated phrases) 2.5 command queuing (stacking) accumulation of a series of command phrases in order to allow their input into the system as a group rather than require that they be entered and executed one at a time 2.6 command phrase phrase including the command (words or their abbreviations) and associated separators and arguments (parameters) EXAMPLE: Command word separator argument1 separator argume
