23、deration of national standards bodies (IS0 member bodies). The work of preparing Intemational 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 comm
24、ittee. Intemational organizations, 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 t
25、echnical committees are circulated to the member bodies for voting. Publication as an Intemational Standard requires approval by at least 75 % of the member bodies casting a vote.

29、NGL 1777 Lb24bb 0787207 127 W EN IS0 9241-13:1998 Introduction This part of IS0 9241 deals with user guidance aspects of software user interfaces. The main purpose of user guidance is to aid the users interaction with the system by - promoting efficient system use; - avoiding unnecessary mental work
30、load; - providing support to users to manage error situations; and - providing support for users of different skill levels. This part of IS0 9241 serves the following types of users: - the designer of the user guidance, who will apply this pari of IS0 9241 during the development process; - designers
31、 of user guidance development tools to be used by dialogue designers; - the buyer, who will reference this pari of IS0 9241 during the product procurement process, and whose end-users will gain from the potential benefits provided by this part; and - those responsible for ensuring that products meet
32、 the recommen- dations in this part of IS0 9241. The ultimate beneficiary of this part of IS0 9241 will be the end-user at the visual display terminal (VDT). It was the needs of this user that provided the ergonomic recommendations in this part of IS0 9241. Although it is unlikely that the end-user
33、will read this part or even know of its existence, its application should provide user interfaces that are more usable, consistent and that enable greater productivity. Application of this part of IS0 9241 involves an understanding of the intended user, the user environment and tasks. User tasks sho
34、uld be listed and key tasks, defined as the most frequent and important tasks, should be explicitly identified. Recommendations on how to use this part of IS0 9241 can be found in Informative Annex A. For practical reasons, the following structure has been chosen for presenting the user guidance rec
35、ommendations: - common guidance recommendations (see clause 5), - prompts (see clause 6), - feedback (see clause 7), - status information (see clause 8), - error management (see clause 9), - on-line help (see clause 1 O). iv - - ST3-BSI BS EN IS0 72ql-13-ENGL 1977 m Lb2qbbS 0787202 Ob3 EN IS0 9241-1
36、3:1998 Ergonomic requirements for office work with visual display terminals (VDTs) - Part 13: User guidance 1 Scope This part of IS0 9241 provides recommendations for user guidance attributes of software user interfaces and their evaluation. User guidance as defined in this part of IS0 9241 is infor
37、mation additional to the regular user-computer- dialogue that is provided to the user on request or is automatically provided by the system. In addition to the general guidance provided in this part of IS0 9241, recommendations concerning dialogue-specific user guidance are provided in IS0 9241-12,
38、IS0 9241-14, IS0 9241-15, IS0 9241-16 and IS0 9241-17. This part of IS0 9241 is applicable to interaction components that aid users in recovering from error condflions. User guidance as covered by this part of IS0 9241 includes recommendations specific to prompts, feedback and status, error manageme
39、nt and on-line help as well as general recommendations common to all these ypes of user guidance. While user support can be provided via other means (e.g., on-line tutorials, on-line documentation, intelligent system performance aids) these types of support are not addressed by this part of IS0 9241
40、 -13. The recommendations in this part of IS0 9241 are formulated to be independent of applications, environment, or implementation technology. They correspond to typical situations involving special needs for information and actions. As with other parts of IS0 9241, this part of IS0 9241 can apply
41、in all or in part. For example, applications that do not have browsable help would not need to follow recommendations concerning this class of user guidance. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of
