This document provides design guidelines and requirements for tactile symbols and characters used for information and marking for people who need non-visual or non-auditory information. It is applicable to products, facilities and equipment in housing and transportation, services and packaging, where tactile symbols and characters may be used.
This document specifies the physical characteristics of tactile symbols and characters for ease of legibility by touch taking into account human abilities of tactile sense and their aging effect. It does not specify semantic characteristics of tactile symbols and characters.
This document is applicable to tactile symbols and characters of convex-type touched by fingers.
It is not applicable to specifically coded tactile symbols or characters such as those of Braille, nor to those with vibratory or temporal changes.
