Scope of the Work

• To develop a technical guideline that assists
  standard developers to implement the ISO/IEC
  Guide 71 in individual standards
• To provide ergonomic principles and data on
  human abilities as a function of age and
  disabilities to be used for the design process of
  the products and environment that take account of
  the needs of older people and people with
  disabilities
