  1. 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 Ergonomics-oriented design using ISO/IEC Guide 71 and ISO/TR 22411 Ken Sagawa, Prime Senior Researcher, National Institute of Advanced Industrial Science and Technology (AIST), Japan

  2. Accessible Design Map & Plan Instruc ３times/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) Article 9 - Accessibility in “UN Convention on the Rights of Persons with Disabilities”

  3. ISO/IEC Guide 71: 2001 Guidelines for standard developers to address the needs of older persons and persons with disabilities Factors to consider 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 Contents labeling Surface temperature Accessible routes Logical process Surface finish Non-allergenic/toxic Acoustics Fail-safe Ventilation Fire-resistance How to design How to consider (Ergonomic issues)

  4. An example of Factors to consider (1) Alternative format (Vision  Tactile) Prepaid cards Containers (milk container)

  5. An example of Factors to consider (2) Sound pressure/frequency (of auditory signals ) Hearing sensitivity and auditory signals Warning Termination Feedback ( From Kurakata et al)

  6. ISO/TR22411 (2008) 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)

  7. Contents of TR22411 (examples) Instructi 3 times/day …………….. MAP & MEMO Reach range (physical) Tactile discrimination Step height (physical strength) Working memory and attention (cognitive) legible font size (vision) Colour combination (vision) Useful visual field (vision) Sound pressure and frequency(hearing)
