What is cognition?
The mental action or process of acquiring knowledge and
understanding through thought, experience, and the senses.
(Oxford Dictionary, 2015)

Perception & cognition
are inter-related
Sensational!

Australia’s National Disability Strategy (2010-2020)
1. Inclusive and accessible communities
2. Rights protection, justice and legislation
3. Economic security
4. Personal and community support
5. Learning and skills
6. Health and wellbeing

Accessibility
The extent to which products, systems, services, environments and
facilities can be used by people from a population with the widest
range of characteristics and capabilities to achieve a specified goal
in a specified context of use.

What if we can’t specify
the goal or context of use?
Principles underlying rules

Universal design to the
rescue!
But how?
![Page 11: Design considerations for people who perceive and process ...universaldesignaustralia.net.au/wp-content/uploads/2016/09/Emily-Steel.pdf · Design considerations for people who perceive](https://reader033.fdocuments.in/reader033/viewer/2022041701/5e418094f080324b131e3275/html5/thumbnails/11.jpg)
Implementation challenges
• Perception that Universal Design restricts creativity; confused with
accessibility using a ‘template’ approach.
• Associated with disability.
• Overemphasis on physical aspects, and lack of understanding of
sensory, cognitive, psychological and social diversity.
• Principles incomplete, complex and ambiguous.
• Concern about additional immediate costs.

Standards for cognitive accessibility
– Consumers identify important and/or troublesome products, and
evaluate the usability.
– Principles that can be applied in the design of all consumer
products.
– Technical standards specify how to test and evaluate whether a
product has the intended features.
– Principles: provide multiple means of engagement, representation
and understanding, action and expression.

Usability
The effectiveness, efficiency and satisfaction with which specified
users achieve specified goals in particular environments.
- Effectiveness: the accuracy and completeness with which specified
users can achieve specified goals in particular environments
- Efficiency: the resources expended in relation to the accuracy and
completeness of goals achieved
- Satisfaction: the comfort and acceptability of the work system to
its users and other people affected by its use

Provide means of engagement
– Engagement, motivation, trust and confidence
– Focus, attention and feedback

Provide multiple means of
representation and understanding
– Language and information
– Spatial orientation and understanding of values and sizes
– Simple, understandable and logical

Provide multiple means of action and
expression
– Communication and expression
– Organisations, planning and time management
– Flexibility and equal opportunities
– Provide options for correction of mistakes
