21、s (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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,
22、 governmental and non- governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the international Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated
23、 to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 9241 -1 5 was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee 4, Ergonomics of human-system interaction.

The description of the individual parts of IS0 9241, their inter
28、relationships, and a description of the expected users of the parts is described in IS0 9241-1. IS0 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 language s
29、yntax, and the computer performs the actions associated with the commands and their parameters. IS0 9241 -1 5 serves the following types of user of this part of IS0 9241 : a) The user-interface designer, who will apply IS0 9241-15 during the development process. b) The buyer, who will reference IS0
30、9241-15 during the product procurement process. c) Evaluators responsible for ensuring that products meet the recommendations in IS0 9241 -1 5. 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
31、patt of IS0 9241. The ultimate beneficiary of this part of IS0 9241 will be the end-user at the VDT. It is the needs of these users that provide the ergonomic recommendations in IS0 9241 -1 5. Although it is unlikely that the end-user will read this patt of IS0 9241 or even know of its existence, it
32、s application should provide user interfaces that are more usable, consistent and that enable greater productivity. In order to apply IS0 9241-15 within the overall context of the ergonomic requirements for human-system int.eraction, it is suggested that users be familiar with the following parts of
33、 9241 : IS0 9241 -1 Ergonomic requirements for office work with visual display terminals (VDTs) - Part 1: General introduction IS0 9241-2 Ergonomic requirements for office work with visual display terminals (VDTs) - Part 2: Guidance on task requirements Ergonomic requirements for office work with vi

35、ber of recommendations, some of which are conditional, concerning command dialogues. Conditional recommendations 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 we
36、re developed primarily by reviewing the existing relevant literature and empirical evidence, then generalizing and formulating this work into recommendations for use by the interface designer andor evaluator. Sources for the individual recommendations are listed in Annex B. Designers and evaluators
37、using IS0 9241-15 need to know that they are developing an interface that will meet the recommendations provided therein. Likewise, the buyer needs a means to determine how a product matches the recommendations in IS0 9241 -1 5. The elements can be tailored due to the “if - then“ structure in IS0 92
38、41-15. Additionally, it is not the intent of IS0 9241-15 that every recommendation should be applied, only those that are relevant. The application of this part of IS0 9241 is expected to improve the overall quality of the command language, but IS0 9241 -1 5 (like any other standard) will not guaran
39、tee the quality of the interface. Quality depends on specific usability criteria as set by the user, buyer or other command-dialogue consumer which may include specifications based on this part of IS0 9241. It should be noted that IS0 9241-10 describes dialogue principles that are relevant for the d
40、esign of command dialogues. These principles should provide the designer and evaluator with additional information concerning the ergonomic rationale for the various recommendations in IS0 9241 -1 5 and, therefore, assist in making tradeoffs. However, it may be necessary to base tradeoffs on other c
41、onsiderations as well. vi - STD-BSI BS EN IS0 72Ll1-L5-ENGL 1778 Lb24bb7 b98583 Y23 U EN IS0 9241-16 : 1997 Ergonomic requirements for off ice work with visual display terminals (VDTs) - Part 15: Command dialogues 1 Scope This part of IS0 9241 provides recommendations for command dialogues used to a
42、ccomplish 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 co
43、mmand 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. Interface design depends upon the task, the user, the environment, and the availa
44、ble technology. Consequently, IS0 9241-15 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 information available conce
45、rning 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). IS0 9241-15 applies to the use of command dialogues, either in conjunction with other dialogues (e.g
46、. 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 IS0 9241 provides recommendations for those “key“ commands (.e. function keys and hot keys) which represent
47、 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 IS0 9241 -1 5. Commands
48、can be accessed through other dialogue techniques (e.g. menu options, forms, direct manipulation). However, these methods do not require recall on the pari 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 noted that IS0 9241-15
49、does not provide guidance for dialogues which use “natural“ language. 2 Definitions For the purposes of this pari of IS0 9241, 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. NOTE Arguments oten include parameters. 2.2 command Whole word, abbreviation, or string of words representing actions requested of the system. 1 2.3 command dialogue; command language Command set(s), phrases, structure and syntax associated with a specifi
