DIN EN ISO 24503:2011-05

This document (EN ISO 24503:2011) 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 disabilities. 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 as 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. This International Standard only applies to products for personal use and is not for commercial, professional, or industrial use. It is based on the principles of accessible design (barrier-free serviceability) set out in ISO/IEC Guide 71, Guidelines for standards developers to address the needs of older persons and persons with disabilities. This document (EN ISO 24503:2011) has been prepared by Technical Committee ISO/TC 159 "Ergonomics" in cooperation with Technical Committee CEN/TC 122 "Ergonomics", the secretariat of which is held by DIN (Germany). The responsible German Committee is NA 023-00-04 GA "Ergonomie für Informationsverarbeitungssysteme" ("Ergonomics for information processing systems") at the Ergonomics Standards Committee (NAErg).
