STANDARDS – Rules, Guides • ISO/IEC Directives • Core procedures for standards development work within ISO and IEC. • Formal explanation of rules guiding the progression of any standardization project. • ISO/IEC Guides • Provide a resource of helpful advice to standards writers . • Help deal with specialist issues, such as consumer needs, when writing standards. • Also useful for people not involved in standards work as the advice they contain can be generally applied to their subject areas.
ISO/IEC GUIDE 71 - 01 Title: Guidelines for standards developers to address the needs of older persons and persons with disability
ISO/IEC GUIDE 71 - 02 • The Guide 71 aims to: • Inform, increase understanding and raise awareness • Outline relationship btw requirements in standards and the accessibility and usability of products and services • Raise awareness of benefits of adopting accessible design principles in terms of wider market The Guide 71 applies to: Products, services and environments The Guide 71: Offers description of body functions or human abilities and the practical implication of impairment
ISO/TR 22411 Title: Ergonomics 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
ISO/TR 22411 • This is a generic standard • The standard is the as guide in addressing accessibility issues in all other standards for products, services and environment
ISO/TR 22411 • The standard addresses key issues which include • Human abilities and the usability of products, services and environments • Relationships between the requirements in standards and the accessibility and usability of products and services • Benefits of adopting international accessible design principles in terms of a wider market
ISO/TR 22411 • The Standard outlines: • The process by which needs of older persons and persons with disabilities may be considered in development of standards • The descriptions of body functions or human abilities and profound implications of impairments
ISO/TR 22411 • The three human abilities that must be addressed when designing accessible products, services and environments are: • Sensory abilities • Physical abilities • Cognitive abilities
SENSORY ABILITIES • Disabilities associated with sensory abilities include • Loss of visual acuity (image appears indistinct) • Loss of distance vision • Perception of colour • Sensitivity to light and speed of adaptation to changing light levels • Design remedy may require tactile and acoustic input
PHYSICAL ABILITIES – 01 • Dexterity:this relates to activities of the hand and arm use, particularly coordinated actions of handling objects, picking objects, manipulation and releasing them using hands, fingers and especially the thumb • Manipulation:Relates to activities of carrying, moving and manipulating objects. Actions involve arms, legs, feet, arms and hands. Actions involve reaching out, lifting, putting down, pulling, pushing etc.
PHYSICAL ABILITIES – 02 • Movement: This involves the activities of maintaining and changing the body positions and transferring oneself from one area to another using legs, feet, arms and hands • Strength and Endurance: Strength is the force generated by contractions of muscle or muscle group. Related weaknesses include grip strength.
PHYSICAL ABILITIES – 03 • Voice: This relates to sound produced by vocal organs, usually speech. Principal consequence is barrier to communication. Alternative forms of communication like sign language, speech amplification, speech synthesis or use of facsimile of keyboard maybe useful
COGNITIVE ABILITIES – 01 • Cognitive abilities relate to central information processing like memory recall, directing attention, thinking, decision making, problem solving, language, perception through sensory information. • Key areas include: intellect, memory and language/literacy
COGNITIVE ABILITIES – 02 • Intellect: Capacity to know, understand and reason. To address disabilities related to this, task complexities may be considered • Memory: Disabilities may relate to specific mental functions of registering and storing information and retrieving it as needed. Possible accessible design criteria involve systems that are “fail-safe” • Language/Literacy: This refers to functions of recognizing and using signs, symbols and other components of language
ISO/TR 22411 –A GLANCE AT CLAUSE 8.12 • 8.12 Ease of handling • 8.12.1 Size, shape and mass • 8.12.2Instruction manuals and locations of marking • 8.12.3 Controls • 8.12.4 Containers and packaging • 8.12.5 Duration of actions • 8.12.6 Time responses • 8.12.7 Elements in a building
THE TC PROCESS - 01 • Traditional key features for product standards • Performance; • Methods of measuring energy & water consumption, noise emission, heat generation etc. • Emerging issues: energy efficiency, accessibility and usability, interoperability • Product safety • Safety requirements • Emerging issues:Vulnerable people
THE TC PROCESS - 02 • Starting point • The will/need to take into account needs of persons with disability. Are you aware of SO/IEC Guide 71? • Do you have ergonomic knowledge and data on human abilities? KS ISO/TR 22411
THE TC PROCESS - 03 Step 1.Take into account the needs of older Persons and persons with disability Step 2. Apply the bridge document. Knowledge and data on human abilities Step 3. “Draft standard” having accessibility features mainstreamed
THE TC PROCESS - 04 • Relevant criteria • User characteristics e.g. visual impairment • Task evaluation e.g. pressing a key • Measurement and measurement instruments • Test procedures
THE TC PROCESS - 05 • Relevant criteria • Recommendations verses requirements • Comparisons verses evaluation
