ERGONOMICS & ACCESSIBILITY

ErgonomicsAn applied science concerned with designing and arranging objects & environments people use in a safer and more efficient manner

Accessibility (ISO/TR 22411)extent to which products, systems, services, environments or facilities can be used by people from a population with the widest range of capabilities to achieve a specified goal in a specified context of use


11

STANDARDS - 02

Standardization process involves experts from various institutions and organizations. The experts form Technical Committees (TC) composed of interested parties/ stakeholders

Standardization process has rules and regulations

Standardization process has guidelines

STANDARDS – Rules, GuidesISO/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.

17

ISO/IEC GUIDE 71 - 01

Title:Guidelines for standards developers to address the needs of older persons and persons with disability

18

ISO/IEC GUIDE 71 - 02The Guide 71 aims to:

a. Inform, increase understanding and raise awareness

b. Outline relationship btw requirements in standards and the accessibility and usability of products and services

c. 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

THE RELATIONSHIP - 01

22

THE RELATIONSHIP - 02

23

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

24

• The standard addresses key issues which include

a. Human abilities and the usability of products, services and environments

b. Relationships between the requirements in standards and the accessibility and usability of products and services

c. Benefits of adopting international accessible design principles in terms of a wider market

ISO/TR 22411

25

• The Standard outlines:a) The process by which needs of older

persons and persons with disabilities may be considered in development of standards

b) The descriptions of body functions or human abilities and profound implications of impairments

ISO/TR 22411

26

ISO/TR 22411

• The three human abilities that must be addressed when designing accessible products, services and environments are:

1. Sensory abilities2. Physical abilities3. Cognitive abilities

27

• Disabilities associated with sensory abilities include

a. Loss of visual acuity (image appears indistinct)b. Loss of distance visionc. Perception of colourd. Sensitivity to light and speed of adaptation to

changing light levels

• Design remedy may require tactile and acoustic input

SENSORY ABILITIES

28

• 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 – 01

29

• 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.


30

• 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


31

• 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 – 01

32

• 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

COGNITIVE ABILITIES – 02

34

THE TC PROCESS - 01Traditional key features for product

standards a. Performance;

Methods of measuring energy & water consumption, noise emission, heat generation etc.

Emerging issues: energy efficiency, accessibility and usability, interoperability

b. Product safety

Safety requirements

Emerging issues: Vulnerable people

35

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

36

THE TC PROCESS - 03

Step 1. Take into account the needs of olderPersons and persons with disability

Step 2. Apply the bridge document. Knowledge and data on human abilities

Step 3. “Draft standard” having accessibilityfeatures mainstreamed

37

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

38

THE TC PROCESS - 05

Relevant criteria

• Recommendations verses requirements

• Comparisons verses evaluation
