19、trol electric operation in devices such as information and communication technologies, office technologies, cooking units, toys, bathroom devices, personal medical devices, cameras, etc. This International Standard provides requirements for improving the accessibility of the consumer products used b
20、y people having visual disabilities, and in cases where visual information is not the primary sense used for accomplishing the task. This International Standard only applies to products for personal use and is not for commercial, professional, or industrial use. This International Standard is based
21、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. EN ISO 24503:2011 (E) DIN EN ISO 24503:2011-05 4 1 Scope This International Standard specifies requirements for the design of t
22、actile dots and tactile bars for use on consumer products to improve accessibility for everyone, including older persons and persons with disabilities. This International Standard is applicable to consumer products used by persons with visual disabilities, and in cases where visual information is no
23、t the primary sense used for accomplishing the task. Alternative tactile methods, such as texture and vibration, and other tactile symbols, such as triangles and squares, are not covered in this International Standard. Alternative feedback methods, such as in acoustic and visual modalities, are not
24、covered in this International Standard. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 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 direc
25、tly 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 control NOTE In this International Standard, functions are limited to starting/stopping and increasing/decreasing. 2.4 tactile symbol sign identifiable and re
26、cognizable by touch 2.5 tactile dot dot-shaped tactile symbol 2.6 tactile bar bar-shaped tactile symbol EN ISO 24503:2011 (E) DIN EN ISO 24503:2011-05 5 3 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
27、following purposes: identification of a function of controls; location information of arrayed controls. 3.2 Controls marked for 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 fun
28、ction of a product. A tactile bar shall be placed on a control whose purpose it is to stop/cancel a function of a product. Controls 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 powe
29、r source When a separate control for the power source is not recognizable by shape and/or size through touch, a tactile dot should 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 w
30、ith a tactile dot on the “increasing side”. When there are more than two controls with an increasing and decreasing function placed 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). Key 1 tactile dot 2 c
31、ontrol with an increasing/decreasing function Figure 1 Control with an increasing/decreasing operation with a tactile dot EN ISO 24503:2011 (E) DIN EN ISO 24503:2011-05 6 3.3 Controls marked for location information For arrayed controls, a tactile dot or bar shall be placed on a specific control to
32、facilitate navigation around the controls. EXAMPLE 1 The f and j keys on a keyboard. EXAMPLE 2 The 5 key on 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 dot
33、s and bars Tactile dots and bars should be placed directly on the control. If this placement is inappropriate, 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 c
34、onjunction with Braille and/or other tactile symbols, special care shall be taken so that they do not interfere 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
35、 to the size of a product. NOTE Some big products have small controls and some small products have big controls. 5.2 Dimension and shape of a tactile dot The dimension and shape of a tactile dot should be within the range shown in Figures 2 and 3, and Table 1.
