Effective Experience – an Unconventional View!

Effective, adj. and n.

“a. Powerful in effect; producing a notable effect; effectual.”

OED – a1398 J. Trevisa tr. Bartholomaeus Anglicus De

Proprietatibus Rerum (BL Add. 27944) (1975) I. xvii. lxxxiv.

Why Not Just Accessibility?

� You could conventionally think of this as accessibility.

� Accessibility connotations of disability.

� I don’t hold with this – access/accessibility is much broader

than disability.

� Effective = ability to produce an effect - regardless of how

that ability does or does not exist.

Access is for Everyone...

“While pedalling a Boris Bike I start

to shuffle in my pocket. Where is

that damn iPhone. Finally, I find it.

The next challenge is to get it out

my pocket whilst still navigating the

Humvee of the bike world.

Eventually, I give up. I pull over and

get my iPhone out. I look up the

nearest docking station with spaces

and get back on my way.”

Figure 39. ‘LiveView Cycle Gadget’; pg. 116

But More Critical for Disabled People...

“For me computer systems are

everything. They’re my hi-fi, my

source of income, my supermarket,

my telephone. They’re my way in.”

blind user.

Barriers to Effectual Use

Visual: Many Many challenges in providing efficient /

effective use

Cognitive: Many types / a large spectrum - under researched.

Hearing: First language is Sign

Physical: Many types - with input solutions. ‘Locked in’ -

brain interfaces?

Combinatorial: Different but low level impairments experienced in

combination.

Barriers to Effectual Use

i18n: Language and understanding.

Literacy: Education and misconception.

Situational: Mobile et al.

Developing Regions: Unconventional use.

Low Income: Device Independence.

It’s a Loop

1. Device Independence;

2. Mobile Browsing;

3. Real World Mobility Technology;

4. Mobile to Mobile Cash Transfer;

5. Pringles WiFi; and

6. Mobile Phone Torch.

Technical Accessibility Issues

I GUIs become a problem;

I Screen Scraping introduced as

a solution - Old Skool; then

I Off-Screen Model (OSM)

replaces Screen Scraping -

richer in meaning.

‘What mainstream technology

uses something like OSM?’

Potted Principles of Effectual User Experience – POUR

‘Perceivable’ Can you ‘see’ it?

‘Operable’ Can you use it?

‘Understandable’ Can you understand it? and

‘Robust’ Is it fault tolerant.

But...

...again I don’t hold with these four only.

Facilitate Perceivability

Questions to think about as you design your prototype:

I Does your system convey information by colour alone but

without an alternate textual description?

I Is there a succinct meaningful name and label for each

interface component – including alternatives for icons, etc.?

I Can the user personalise the interface settings, including

different styles and sizes of typography, fore and background

colours, and default interface look and feel?

I How easy is it to find and interact interface controls and the

shortcuts too them?

I Have you provided keyboard focus and text cursors, and will

your system restore it’s previous state when regaining focus?

...expanded in ‘Facilitate Perceivability’ (pg. 130)

shortcuts too them?

Facilitate Openness

I If you have provided succinct meaningful name and label for

each interface component – including alternatives for icons,

and the like – are these names displayed and available to

third-party technology?

I Is you software open such that its information is available to

third part systems including conventional assistive

technologies?

I Does your software allow input and manipulation by these

third party systems?

I If your systems is closed then does it allow all input and

output to pass through to third-party software?

I Can the user control all aspects of an audio - visual

presentation (such as a video)?

I Can the user personalise the interaction settings, and change

the length of any timed events?

I Are all functions/interface components/interactions able to

be controlled via the keyboard?

be controlled via a mouse like pointer controller?

I Are all multiple chorded key presses available in a sticky-key

sequential form?

interface component – including alternatives for icons, and

the like?

I Are all interface control and interaction features well

documented?

I Do all error or alert messages give consistent information,

appear in a consistent place, and facilitate movement to the

site of those errors?

I Do you follow the OS keyboard conventions and best

practice and style guides?

I Have you tied into the system wide spell checker?
