9、rinciples of ergonomics and ergonomic design” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Ergonomie (Ergonomics Standards Committee), Technical Committee NA 023-00-01 GA Gemeinschaftsausschuss NAErg/NAM Grund-stze der Ergonomie. ISO 20
10、282 consists of the following parts, under the general title Ease of operation of everyday products: Part 1: Design requirements for context of use and user characteristics Part 2: Test method for walk-up- and-use products (DIN ISO/TS 20282-2) Part 3 “Test method for consumer products” ISO/PAS 20282
11、-3 and Part 4 “Test method for the installation of consumer products” ISO/PAS 20282-4 will not be published as German Standards. Users of this standard should note that a terminological imprecision in the original text became evident when this document was translated from English into German. The ti
12、tle of this Part 1 of DIN ISO 20282 is: “Ease of operation of everyday products Design requirements for context of use and user characteristics”. This wording is defined in Clause 3 “Terms and definitions” as “Usability of the user interface”. Clause 1 “Scope” states that the “ease of operation addr
13、esses a subset of the concept of usability concerned with the user interface by taking account of ”. The introduction to this Part 1 of DIN ISO 20282, however, uses the short form “usability” in several places. As a general concept for various properties relating to usage, this could be misinterpret
14、ed in the present context. The German national committee thus is obliged to point out that this Part 1 of DIN ISO 20282 deals with the usability of the user interface(s) only, i.e. with the user-friendliness of the user interface of everyday products, and not with the usability of the products thems
15、elves. The DIN Standards corresponding to the International Standards referred to in the EN are as follows: ISO 7250 DIN EN ISO 7250 ISO 9241-11 DIN EN ISO 9241-11 ISO 9355-1 DIN EN 894-1 ISO 9355-2 DIN EN 894-2 ISO 9355-3 DIN EN 894-3 ISO 13407 DIN EN ISO 13407 IEC/TR 61997 DIN 40020 National Annex
16、 NA (informative) Bibliography 1 DIN 40020, Guidelines for the user interface in multimedia equipment for general purpose use (IEC/TR 61997:2001) Introduction An increasing number of everyday products include computer technology, making them more complex. Users need to understand how to operate prod
17、ucts in order to benefit from the functionality they offer, so usability is a key factor in determining a products success. As product complexity increases, the challenge for the user in understanding how to use the various functions of the product also increases, and for the producer it can be hard
18、er to design sufficiently usable products. Products with low usability often require the assistance of other people in order to be used, and this can result in frustrated users as well as in extra costs for the producer and vendor. Many companies have realized the importance of the usability of thei
19、r products and employ usability specialists in usability laboratories. Many test organisations include usability in their evaluation procedures. ISO 20282 is based on ISO 9241-11, which provides guidance on the specification and measurement of usability in general. ISO 20282 applies ISO 9241-11 to t
20、he user interfaces of everyday products. The focus on everyday products reflects the fact that many of the products we see around us on a regular basis still suffer from fundamental usability problems. The focus on user interfaces reflects the situation that while there are many factors that may hav
21、e important effects on usability, all interactive products will have a user interface whose quality can have significant positive or negative effects that facilitate or hamper the usage of the product. Everyday products include consumer products and walk-up-and-use products. For everyday products it
22、 is particularly critical to ensure that the interface enables the user to achieve their main goal(s). The focus on the main goal(s) reflects the outcomes that all users, or a large majority of them, wish to achieve, e.g. to use a telephone to make or receive a phone call, to use a ticket machine to
23、 buy a train ticket, or to use a television set to watch a television programme. The term “ease of operation” refers to this subset of the concept of usability and the specific measures used to support users in achieving their main goal(s). Everyday products are designed for an intended user populat
24、ion, which in general ought to be assumed to include people with a wide range of user characteristics. This part of ISO 20282 describes the user characteristics to be accounted for in the design of an everyday product. In recognizing that the population of older persons of the world is increasing, i
