Accessibility is for the Disabled


Accessibility is for EVERYONE!

RIGHT


So what’s Accessibility?
As per the dictionary, Accessibility means:
• Convenience
• Easy of access
• User-friendliness
• Easy of understanding
• Easy of use

Persons with disabilities are the most hit with
accessibility issues!


Disabled = Everyone!
Its about time we do some reality check on the term
disabled!
HEARING MOBILITY
Deaf: can’t hear Physical disability: unable to move one or
Hard-of-hearing or hearing impaired: more limbs, fingers, or toes
can hear only with amplification or can Motor skills impairment:
hear in one ear only unable to press one key at a time, unable
to press a key without duplicate
keystrokes, unable to use a mouse

VISION LEARNING
Blind: can’t see Dyslexia: difficulty with reading
Visually-impaired: can’t read small type or
distinguish certain colors
Color-blind: can’t distinguish certain
colors


Let’s look at some real life examples
• People using a wheel chair
• Those using a white cane
• Those wearing hearing aids
• Those using crutches

These are the first instances that come to our mind! But what about..

• Forgetting glasses at home - finding it complicated to work on the computer
• With age, each one of us acquires some sort of disabilities including;
• memory loss,
• hard-of-hearing,
• deteriorating vision ,
• adversity in climbing stairs, etc

In our every day life we all face impairments, activity limitations, and
participations!


So the point is ...

“Disability is a socially created problem and not an
attribute of an individual”

Web Accessibility Quick Fixes
• Color and Contrast - Provide sufficient color contrast for the foreground and background color
combinations.
• Color can’t be used as a “sole indicator of meaning”
• Font Sizes - Make your default font size reasonably big (at least 10 point) so that very few users
have to resort to manual overrides.
• Icons and Texts for Better Context
• Sensory Characteristics - Do not use size, shape or location to provide any information
• Different heading levels should be appropriately used.
• Alt text inclusion for images is critical and should be null for spacer images and for images that are
included with same anchor tag for a textual link.
• Expansion for abbreviations is essential
• Keyboard access is very critical, considering that there could be few users who wouldn’t be using
mouse at all.
• “Skip to Main Content” should be available.
• Row and Column headers should be provided for all data tables, <th> tags.
• Descriptive and informative page titles
• Ensure all hyperlinks use descriptive and meaningful text, avoiding short-hand language like
'Click here';
• Captions must be provided for any multimedia (audio/visual) content
• Avoid Flickering - Pages shall be designed to avoid causing the screen to flicker with a frequency
greater than2 Hz and lower than 55 Hz.
