New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 24508 : 2019 ‘Ergonomics - Accessible design - Guidelines for designing tactile symbols and characters’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Ergonomics Sectional Committee and approval of the Production and General Engineering Division Council.

Providing tactile information such as raised symbols or characters is one method for making products or environments more accessible to users who need to access information using a modality that depends on neither vision nor hearing. The use of tactile information has become an increasingly important method for supporting accessible design of products services and environments. The use of tactile information in a design requires proper consideration to best support human tactile senses so that the information is easily and correctly understandable. Guidelines for designing tactile symbols and characters based on ergonomic knowledge of human tactile abilities are therefore necessary for such design.
