14、) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the elect

15、rical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, go

16、vernmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal deci

17、sions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for

18、 international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standard

19、s transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot

20、be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this technical report may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such pat

21、ent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example

22、 “state of the art“. IEC 61997, which is a technical report, has been prepared by IEC technical committee 100: Audio, video and multimedia systems and equipment. The text of this technical report is based on the following documents: Enquiry draft Report on voting 100/144/CDV 100/249/RVC Full informa

23、tion on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. The committee has decided that the contents of this publication will remain unchanged u

24、ntil 2006. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. This document which is purely informative is not to be regarded as an International Standard. A bilingual version of this publication may be issued at a later date. 4 TR 61997 IEC:2001

25、(E) INTRODUCTION There is growing use of multimedia equipment of every kind both in society and in the home; huge amounts of information are being exchanged both at the individual level and throughout society. However, as things stand it can easily be imagined that when this equipment is brought int

26、o the home, the complex and inconvenient operation seen as characteristic of multimedia equipment featuring electronic functions will make the equipment difficult, inconvenient and unprofitable to use; and incorrect operation may lead to confusion. If the use of various multimedia appliances is to s

27、pread together with technological developments and the more advanced use of information, greater care than ever must be taken in the design of user interfaces that will make the equipment easy to use even by ordinary people who have received no special training in operating the equipment. The situat

28、ion must not be allowed to arise where a multimedia appliance provokes a negative reaction because it is difficult to understand or difficult to use. The designer is well acquainted with the appliance, the content of the system, and the peripherals; but a person operating the equipment for the first

29、 time starts with no knowledge at all. The purpose of these guidelines is to take note of those inconveniences in the operation of multimedia equipment observed today, and to specify check-points that should be given primary consideration in the development of good multimedia products and systems th

30、at the general, non-professional user can use with confidence. It is difficult to draw up detailed, concrete standards for products that have yet to be manufactured. In addition, the application to various appliances of standards drawn up over a period of time is impracticable in the field of multim

31、edia, which is developing so rapidly. For this reason we believe it is essential for basic, minimum-level user interface guidelines to be drawn up at an early date, even if such guidelines are incomplete as standards. The items taken up here are those concerned only with the problems of operation an

32、d use characteristic of multimedia equipment and systems, and assume the existence of detailed guidelines or standards for user interface recommended by various international bodies. Accordingly, other standards or guidelines as given in the annex should be consulted with regard to detailed ergonomi

33、c design standards and design standards shared with other, ordinary appliances. Observation of these guidelines will lead to the kind of multimedia appliances that will satisfy user expectations, and at the same time will promote free competition in the development of multimedia equipment and system

34、s.TR 61997 IEC:2001(E) 5 GUIDELINES FOR THE USER INTERFACE IN MULTIMEDIA EQUIPMENT FOR GENERAL PURPOSE USE 1 Scope This Technical Report applies to the designing of multimedia equipment such as information and communications equipment or audio-video equipment and systems. In this report, multimedia

35、equipment (systems) refers to equipment or systems mainly intended for use by the general public, either in the home or in public institutions. It is assumed that these products are meant to be used by anyone, including children, adults and senior citizens, using the equipment for the first time wit

36、hout any special previous training. The scope of the user interface covered by these guidelines is limited to the problems peculiar to multimedia equipment. Numerical details regarding user interface ergonomics, such as the size and spacing of switches, the expressive use of letters and pictograms,

37、etc. are the province of the ergonomic standards and guidelines being considered by various organizations and are excluded from this report. 2 Reference documents IEC 60447, Man-machine-interface (MMI) Actuating principles ISO 9241-10 to ISO 9241-17, Ergonomic requirements for office work with visua

44、 which illustrates the whole structure of user interfaces for multimedia equipment. This model is composed of three dimensions: 1) media, 2) abstraction, and 3) QOI (quality of interface). The media dimension classifies user interfaces by the feedback media of equipment. It consists of visual, audio

45、, mechanical, and others. The abstraction dimension classifies user interfaces by the abstraction of interactions. It consists of the lexical, syntax, and semantic layers. The QOI dimension classifies user interfaces by their quality in the equipment. It consists of the minimum, standard, and excell

46、ent levels.

47、 model” Reference model of user interfaces for multimedia equipment 4.1 Dimension of abstraction User interfaces can often be divided into three layers: 1) lexical layer, 2) syntax layer and 3) semantics layer. The lexical layer represents primitive operations and their feedback of basic input parts

48、, and output methods of basic output parts. The syntax layer handles the way to compose the basic input/output parts. Concretely, it incorporates with the operation sequences and layouts of these parts. The semantics layer defines the relationship between user interfaces and functions of the equipme
