Accessible Design: Which everyone do you mean?

What does diversity even mean?

What about ability? expertise?

• blind • low-vision • hearing • mobility/dexterity

(fine motor control, low-strength, single-handedness)

• cognitive (attention, memory-related, literacy,

routines/predictability) • vestibular issues • speech

3 types of relationships

Explicit, implicit and content based relationships.

Low-vision challenges

Windows High Contrast Mode: background images disappear.

Low-vision tip: review your interfaces in High Contrast Mode to look for loss of functionality or meaning.

Not sure?

Use layout to create the right chunks.Use pattern of use to lead the eye to action.

Examine your interfaces using the straw test to unearth layout and design challenges for people with low-vision.

Mobility and dexterity challenges

To help ensure accessibility, provide multiple means to achieve the same goal.

Cognitive challenges

Once upon a time, there was a little girl who

lived with her mother in a little cottage, on the

edge of a large, dark forest. This little girl

often wore a pretty little red cloak with her little

red hat, and for this reason people called her Little

Red Riding Hood.

What’s the impact of aging on what we do?

What’s the impact of culture on what we do?

Edward T. Hall

Beyond Culturehigh and low context cultures

High Context Culture Low Context Culture

collectivist individualist

group empowerment self empowerment

authoritarian style information delivery

exploratory

accuracy valued over speed speed valued over accuracy

context is implied based on being in that culture

context is explicit and self contained

Of course, this is a continuum and not a dichotomy.
