9、997/Amd.1:2001(E) ISO 2001 All rights reserved iiiForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each me

International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International Ele

Theseparts are concerned with the ergonomic design of software user interfaces.The goal of this Amendment (complementing ISO 9241-1) is to help readers of ISO 9241-10 to ISO 9241-17 inGbe gaining an overview on the content of ISO 9241-10 to ISO 9241-17,Gbe un

It was the needs of theseusers that provided the ergonomic recommendations in ISO 9241-10 to ISO 9241-17. Although it is unlikely that theend user will read ISO

24、e (users, tasks, environment) and the definition of usability in terms ofeffectiveness, efficiency and satisfaction (ISO 9241-11);Gbe characteristics of presented information and recommendations for the presentation of information (ISO 9241-12);Gbe recommendations for user guidance; these apply to a
25、ll dialogue techniques (ISO 9241-13);Gbe recommendations for the usage of dialogue techniques (ISO 9241-14 to ISO 9241-17).The specification or design of human-computer dialogues should be driven by an understanding of therequirements of the users, their tasks, the environment and the available tech
26、nology. There are usually severaloptions and the final choice may be influenced by the desire for consistency (e.g. with existing organizationalpractices or across a range of systems). Decisions about the overall suitability of human-computer dialogues canbe assisted by reference to standards contai
27、ning general principles of dialogue design i.e. ISO 9241-10. Specificrecommendations for dialogue design are addressed in ISO 9241-14 to ISO 9241-17.A.1.2 Relationship between ISO 9241-10 to ISO 9241-17Figure A.1 illustrates the structure of ISO 9241-10 to ISO 9241-17, reflecting the nature of the i

29、level ergonomic principles that apply to the design of dialoguesbetween humans and information systems. ISO 9241-10 provides seven principles of good practice for the designof the dialogue between the user and the interface software.These seven principles are:Gbe suitability for the task;Gbe self-de
30、scriptiveness;Gbe controllability;Gbe conformity with user expectations;Gbe error tolerance;Gbe suitability for individualization;Gbe suitability for learning.The principles given in ISO 9241-10 form the basis for understanding any specific software-ergonomicrecommendation given in other parts of IS
31、O 9241. These principles do not permit strict compliance checking,although it may be possible to evaluate whether these principles have been generally applied.Amendment 1:2007 to CAN/CSA-ISO 9241-1-00ISO 9241-1:1997/Amd.1:2001(E) ISO 2001 All rights reserved 5A.1.4 ISO 9241-11 “Guidance on usability
32、”ISO 9241-11 introduces the concept of usability, but does not contain specific recommendations in terms of productattributes. It is concerned with the extent to which the users of products are able to achieve specified goalseffectively, efficiently and with satisfaction in a given context of use (u
33、sers, tasks and environment). This frameworkcan be used as part of an ergonomics requirements specification. It includes descriptions of the context of use, theevaluation procedures to be carried out and the criterion measures to be satisfied when the usability of the systemis to be evaluated.A.1.5
34、Structure within ISO 9241-12 to ISO 9241-17A.1.5.1 Structural organizationThe following structure applies to each of these ISO 9241 parts.Gbe ForewordGbe IntroductionGbe ScopeGbe Normative referencesGbe DefinitionsGbe Application clauseGbe RecommendationsGbe AnnexesA.1.5.2 Application clauseWithin t
35、he application clause of ISO 9241-12 to ISO 9241-17 the appropriateness of the specific part is explained interms ofGbe user and organizational characteristics,Gbe task characteristics,Gbe system capabilities.NOTE More details are provided on these characteristics in A.3.2.The application clause als
36、o explains how the recommendations given in the standard should be applied. Eachrecommendation should be evaluated for its applicability and, if judged to be applicable, should be implemented inthe relevant dialogue technique unless there is evidence that to do so would cause deviation from the desi
37、gnobjectives or would result in an overall degradation in usability.Furthermore, each part of ISO 9241-12 to ISO 9241-17 states: “if a product is claimed to have met the applicablerecommendations in this part of ISO 9241, the procedure used in establishing requirements for, developing, and/orevaluat
38、ing the shall be specified. The level of specification of the procedure is a matter of negotiation betweenthe involved parties”.Amendment 1:2007 to CAN/CSA-ISO 9241-1-00ISO 9241-1:1997/Amd.1:2001(E)6 ISO 2001 All rights reservedA.1.5.3 Recommendations clauseThe recommendations clause within each par
39、t of ISO 9241-12 to ISO 9241-17 contains the recommendations ofthe particular part of ISO 9241. Many of these recommendations are conditional recommendations (or “if”statements). Often the “if” statement refers to the context of use e.g. in ISO 9241-14, “If appropriate for the task, indeeply structu
40、red menus (more than 3 levels), users should be provided with the capability to go from one part(node) of the structure to another without returning to the initial common node”.A.1.5.4 AnnexesAnnex A within ISO 9241-12 to ISO 9241-17 provides an example of a procedure for determining whether theappl
41、icable recommendations in the particular part of ISO 9241 have been met. It should be noted that theprocedure described is provided as guidance and is not a rigid process to be used as a substitute for the standarditself. This procedure provides a two-stage process for determining which recommendati
42、ons are relevant, and fordetermining whether those relevant recommendations have been adhered to.Annex B of ISO 9241-14 gives examples of application.In addition, ISO 9241-12 to ISO 9241-17 each contain a bibliography with source documents on which eachstandard is based.A.1.6 ISO 9241-12 “Presentati
43、on of information”ISO 9241-12 introduces characteristics of presented information. These characteristics are the following:Gbe Clarity (the information content is conveyed quickly and accurately);Gbe Discriminability (the displayed information can be distinguished accurately);Gbe Conciseness (users
44、are given only the information necessary to accomplish the task);Gbe Consistency (the same information is presented in the same way throughout the application, according to theusers expectation);Gbe Detectability (users attention is directed towards information required);Gbe Legibility (information
45、is easy to read);Gbe Comprehensibility (meaning is clearly understandable, unambiguous, interpretable and recognizable).The characteristics of presented information given in ISO 9241-12 apply to visual design aspects of user guidance(see A.1.7) and any specific dialogue techniques (see A.1.8) employ
46、ed in a software package. ISO 9241-12 alsogives recommendations on the presentation of information. For example, ISO 9241-12 recommends that groups ofinformation items should be perceptually distinct by spacing and location without giving precise criteria for this.However, this recommendation can be
47、 used by tool designers and style guide designers to set up rules for theirspecific design environment.A.1.7 ISO 9241-13 “User guidance”ISO 9241-13 provides recommendations for user guidance provided by software user interfaces and theirevaluation. User guidance as defined in ISO 9241-13 is addition
48、al information beyond the regular user-computer-dialogue that is provided to the user on request or is automatically provided by the system, for example, statusinformation, feedback messages and on-line help. User guidance is always appropriate and should help users inaccomplishing their goals with
49、the system. Sufficient user guidance should be provided so that users accomplishthe task that the system was designed to support without undue effort or stress. Any specific dialogue technique(see A.1.8) incorporates user guidance, for example, by highlighting a selected menu item or by underlining a fieldlabel of a required entry field. Therefore, the recommendations given in ISO 9241-13 should always be consideredwhen designing a specific dialogue technique.Amendment 1:2007 to CAN/CSA-ISO 9241-1-00ISO 9241-1:1997/Amd.1:2001(E) ISO 200
