4、owwww.beuth.deDocument comprises 29 pagesDIN EN ISO 9241-304:2009-06 2 National foreword This standard has been prepared by Technical Committee ISO/TC 159 “Ergonomics”, Subcommittee SC 4 “Ergonomics of human-system interaction”, Working Group WG 2 “Visual display requirements” in collaboration with
5、Technical Committee CEN/TC 122 “Ergonomics” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Ergonomie (Ergonomics Standards Committee), Working Group NA 023-00-04-02 AK Visuelle Anforderungen an Bildschirme. ISO 9241 was originally develop
6、ed as a seventeen-part International Standard on the ergonomics requirements for office work with visual display terminals. As part of the standards review process, a major restructuring of ISO 9241 was agreed to broaden its scope, to incorporate other relevant standards and to make it more usable.
7、The general title of the revised ISO 9241, “Ergonomics of human-system interaction”, reflects these changes and aligns the standard with the overall title and scope of Technical Committee ISO/TC 159, Subcommittee SC 4. The revised multipart standard is structured as series of standards numbered in t
8、he “hundreds”: the 100 series deals with software interfaces, the 200 series with human centred design, the 300 series with visual displays, the 400 series with physical input devices, and so on. See National Annex NA for an overview of the entire ISO 9241 series. The DIN Standards corresponding to

EN ISO 9241-304:2008 (E) DIN EN ISO 9241-304:2009-06 3Introduction ISO 9241 was originally developed as a seventeen-part International Standard on the ergonomics requirements for office work with visual display terminals. As part of the standards review process, a major restructur
33、ing of ISO 9241 was agreed to broaden its scope, to incorporate other relevant standards and to make it more usable. The general title of the revised ISO 9241, “Ergonomics of human-system interaction”, reflects these changes and aligns the standard with the overall title and scope of Technical Commi
34、ttee ISO/TC 159, Subcommittee SC 4. The revised multipart standard is structured as series of standards numbered in the “hundreds”: the 100 series deals with software interfaces, the 200 series with human centred design, the 300 series with visual displays, the 400 series with physical input devices
35、, and so on. See Annex A for an overview of the entire ISO 9241 series. ISO 9241-3:1992, Annex C, offered users a provisional alternative method for testing the visual quality of a display, intended for novel display technologies for which no optical test method was available. The Amendment ISO 9241
36、-3:1992/Amd.1:2000 replaced this test method and made the previously informative Annex C normative. ISO 9241-7:1998, ISO 9241-8:1997 and ISO 13406-2:2001 (all three of which have since been cancelled and replaced by other parts of the ISO 9241 “300” subseries) referred to that Amendment as providing
37、 an alternative user performance test method. This part of ISO 9421 not only incorporates the Amendment, but extends its basis to provide guidance on the general process of assessing the visual ergonomics of displays in a specific context of use by means of a user performance test method. The test m
38、ethod specified in this part of ISO 9241 is applicable only to user tasks involving the handling and processing of text. However, it is expected that test procedures will also be developed for using maps and for handling and interpreting photographs and moving images, with these then being incorpora
39、ted into a future edition. The structure of this part of ISO 9241 is an exception in the ISO 9241 “300” subseries in that it establishes the conformance of a visual display used for text rendition according to its own user performance test method, instead of by means of a compliance route given in I
40、SO 9241-307 (in which no compliance route relevant to this part of ISO 9241 is provided). EN ISO 9241-304:2008 (E) DIN EN ISO 9241-304:2009-06 41 Scope This part of ISO 9241 provides guidance for assessing the visual ergonomics of display technologies with user performance test methods (as opposed t
41、o the optical test methods given in ISO 9241-305). Its use will help to ensure that, for a given context of use, a display meets minimum visual ergonomics requirements. It covers only visual attributes and does not address the ergonomics or usability of the whole product that houses a visual display
42、. The general principles laid down by this part of ISO 9241 apply to any colour or monochrome visual display attached to a system with which human beings interact. This includes, but is not limited to, visual displays used with desktop and portable computers, those used on mobile devices such as mob
43、ile telephones, digital cameras and personal digital assistants, and status displays used on consumer electronics equipment such as printers, in-car navigation systems and microwave ovens. It extends the basic idea of the visual performance and comfort test specified in ISO 9241-3:1992/Amd.1:2000 to
44、 the use of the performance and judgment of the display end users themselves for evaluating the quality of a display, and includes a more diverse range of technologies, users, tasks and environments. Because of this diversity, it is not feasible for this part of ISO 9241 to stipulate a single, gener
45、ic test method that can be used with all display technologies. Instead, the basic principles for generating a test method are given. This method will be valid for evaluating specific displays in specific contexts of use: the method generated according to Clause 8 is applicable only to tasks involvin
46、g the handling and processing of text. No other examples are given. An essential property of the process is that it permits the verification of the usability of a visual display for a representative task, performed by representative users, taking their performance and judgment as measured quality va
47、lues. It does not, however, permit the measurement of specific perceptual attributes such as luminance contrast or display flicker in isolation. The main users of this part of ISO 9241 will be those who procure displays or who need to measure display performance during product development. Its appli
48、cation assumes a background in behavioural science. 2 Normative references The following referenced documents are indispensable for the application of this document.
