15、eword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a tech

16、nical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

17、 electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated t

18、o the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for

19、 identifying any or all such patent rights. ISO 24503 was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC 4, Ergonomics of human-system interaction.

This International Standard only applies to products for personal use and is not for commercial, professional, or industrial us

This International Standard is based on the principles of accessible design set out in ISO/IEC Guide 71, Guidelines for standards developers to address the needs of older persons and persons with disabilities.

23、ed 1Ergonomics Accessible design Tactile dots and bars on consumer products 1 Scope This International Standard specifies requirements for the design of tactile dots and tactile bars for use on consumer products to improve accessibility for everyone, including older persons and persons with disabili

24、ties. This International Standard is applicable to consumer products used by persons with visual disabilities, and in cases where visual information is not the primary sense used for accomplishing the task. Alternative tactile methods, such as texture and vibration, and other tactile symbols, such a

25、s triangles and squares, are not covered in this International Standard. Alternative feedback methods, such as in acoustic and visual modalities, are not covered in this International Standard. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1

26、consumer product product that is intended to be acquired and used by an individual for personal rather than professional use 2.2 control device that directly responds to an action of the operator, e.g. by the operator applying pressure 2.3 function action that is triggered by the operation of a cont

28、O 2011 All rights reserved3 Controls marked with tactile dots and bars 3.1 General Tactile dots and/or tactile bars shall be placed on the controls of a device to serve the following purposes: identification of a function of controls; location information of arrayed controls. 3.2 Controls marked for

29、 identification of a function 3.2.1 Controls for starting or stopping/canceling functions A tactile dot shall be placed on a control whose purpose it is to start a major function of a product. A tactile bar shall be placed on a control whose purpose it is to stop/cancel a function of a product. Cont

30、rols capable of both starting and stopping a major function of a product, such as a push-button ON/OFF switch, shall be marked only by a tactile dot. 3.2.2 Controls for power source When a separate control for the power source is not recognizable by shape and/or size through touch, a tactile dot sho

31、uld be placed on the control of the power source. 3.2.3 Controls with an increasing/decreasing function Controls with an increasing and decreasing function shall be marked with a tactile dot on the “increasing side”. When there are more than two controls with an increasing and decreasing function pl

32、aced in an array, a control or controls to be marked with a tactile dot can be selected. EXAMPLE Control of a remote TV channel changer (see Figure 1).

EXAMPLE 1 The f and j keys on a keyboard. EXAMPLE 2 The 5 key on

34、 a numerical keypad. 4 Positioning of tactile dots and bars 4.1 General In all cases, tactile dots and bars shall be easily found and clearly recognizable by touch. 4.2 Placement of tactile dots and bars Tactile dots and bars should be placed directly on the control. If this placement is inappropria

35、te, tactile dots and bars may be placed on a stationary surface in close proximity to the control. 4.3 Joint use with Braille and/or other tactile symbols When placing a tactile dot or bar in conjunction with Braille and/or other tactile symbols, special care shall be taken so that they do not inter

36、fere with each other. 5 Dimensions and shapes of tactile dots and bars 5.1 General The dimensions of tactile dots and bars shall be adjusted according to the size of the associated control, not to the size of a product. NOTE Some big products have small controls and some small products have big cont
