1 International Telecommunication Union Geneva, 2 November 2009 Ergonomics-oriented design using ISO/IEC Guide 71 and ISO/TR Ken Sagawa, Prime Senior Researcher, National Institute of Advanced Industrial Science and Technology (AIST), Japan ITU-T Workshop "The impact of the United Nations Convention on the Rights of Persons with Disabilities on the work of the ITU-T" Geneva, 2 November 2009

2 International Telecommunication Union ITU-T Workshop on Accessibility Geneva, 2 November Accessible Design Instruc times/day Extending standard design to people with special requirements (older persons and persons with disabilities) to maximize the number of potential users (from ISO/IEC Guide 71) Map & Plan Article 9 - Accessibility in UN Convention on the Rights of Persons with Disabilities

3 International Telecommunication Union ITU-T Workshop on Accessibility Geneva, 2 November Guidelines for standard developers to address the needs of older persons and persons with disabilities ISO/IEC Guide 71: 2001 Alternative format Location/Layout Lighting/glare Colour/contrast Size/style of font Clear language Symbols/drawings Volume/frequency Slow pace Distinctive form Ease of handling Expiration date making How to design How to consider Contents labeling Surface temperature Accessible routes Logical process Surface finish Non-allergenic/toxic Acoustics Fail-safe Ventilation Fire-resistance Factors to consider (Ergonomic issues)

6 International Telecommunication Union ISO/TR22411 (2008) ITU-T Workshop on Accessibility Geneva, 2 November ISO/TR 22411: 2008 Ergonomic data and guidelines for the application of ISO/IEC Guide 71 to products and services to address the needs of older persons and persons with disabilities. A collection of ergonomic data and design considerations relevant for accessible design to implement ISO/IEC Guide 71 (Developed by TC159/WG2)
