How to design and develop

in an inclusive way

Thinking about accessibility

1 in 7

1 BillionPeople with long term disability worldwide

20%11.2 MillionPeople has some type

of disability in the U.K.

Everyone has challenges

► Disability is more common than you may imagine.

► We will all experience disability at some point.

► By the age of 45 most of us will need glasses -

glasses are considered as an assistive tech.

► Yet many websites do not support dynamic text.

► Many on iPhone use 'Large Text,' many apps are

still not compatible.

Acquiring a disability ≠

being born with a disability

► Molly was born deaf but sighted and then lost

vision.

► Molly is now registered blind however still rely on

the remaining vision I have left (5% in one eye)

► Many think if you are blind you use auditory tech

► Being born blind if different to being born sighted.

► Only 5% of blind people have no useful sight.

► The rest have some, however not completely

useful.

So, what is the best way to think about

designing for inclusion?

Exemplar examples of

inclusive design

are formed from

user needs

not just compliance

What’s wrong

with this

picture?

Designing for extremes

Vision

Ability to see, or

process visual

information

Hearing

Ability to hear, or

process acoustic

information

Motor

Ability to interact

with a device

accurately and

quickly

Cognitive

Ability in mentally

demanding areas;

reading, memory,

attention, complex

concepts or language

Types of impairment

Vision

Blindness,

low vision &

colour blindness

Hearing

Hearing loss

Motor

Dyspraxia,

RSI, arthritis

and

cerebral palsy

Cognitive

Down’s syndrome,

Asperger’s and

dyslexia, learning

difficulties

Types of impairment – long term

Vision

Forgot my glasses

Glare when using a

device in bright

sunlight

Hearing

Communication

within a noisy

environment

Motor

Temporary injury

such as a broken

wrist

Carrying a child

Cognitive

Medication,

Tiredness, Stress,

Hangover :D

Types of impairment – temporary & situational

Let’s normalise inclusive design

When we get it right, it’s invisible

Zoom on devices

Captions in videos

A lot of the issues we discover

from users of assistive technology

are usability issues

What can you do to make your products

more inclusive?

Consider colour and contrast

ChromeLens

to the rescue

2.7 million

people in the

UK are colour

blind

Design hit areas to be easy to click or tap

Standard

touch size of

7-10mm

Provide

3-5mm

inactive space

around

elements

Design for comfort

iPhone 4

Design for comfort

iPhone 4 iPhone 5 iPhone 6 iPhone 6+

Design for comfort

iPhone 4 iPhone 5 iPhone 6 iPhone 6+

Design for readability

Clear

visual

hierarchy

Headings,

headings,

headings

10-15

words on a

line

Reading age

of 11-12 years is

generally good

practice

Braille Institute: VisionSim

Help users fix errors

Show;

What the error is,

Where the error is,

and

How to solve it

Think carefully before using custom controls

Custom

controls can

be very

empowering

or very

prohibitive

.

Design for the full spectrum of your users

.

Can you find any black holes?

Content can

be hidden if

you do not

use A tags for

actions

Why inclusive design really matters

Everyone will experience a real need for

inclusive services at least once in their

lives.

Consider everyone's journey.
