Levels of processing
Donald Norman, "Emotional design"
Visceral
Behavioural
Reflective
What is "cool"?
Karen Holtzblatt (InContext)
Accomplish Direct into action
Connection The hassle factor
Identity The delta
Sensation
What is "cool"?
Accomplish my intent anywhere, on my time
Direct into action without hassle
Connection
Identity
Sensation & Aesthetics
Achieving this
Requirements-driven development does
not respond to what people really value
Need to evaluate and refine designs
Need to elicit the real user requirements
Bill Buxton, “Sketching User Experiences”
Laseau (1980) – cited by Buxton
Design is a negative craft
Leonardo Da Vinci (c. 1488) - Wikipedia
Picasso, “Don Quijote” (1955) - Wikipedia
We need to sketch behaviour
Sketches
Fast
Cheap
Plentiful
Disposable
Sketches vs prototypes
Continuum: start with sketches, gradually
use prototypes as the product becomes
more defined
Benefits
Ideation
Organise, clarify your thoughts
Communication
Thought aid
Ideation, “Exhaust the design space”
Communication (designers, community)
Techniques and Examples

In GNOME
Communication of design decisions, a
problem in GNOME
Small teams, a lot of potential
stakeholders
Remote + different organisations
In summary...
Turn off your computer from time to time :-)
Grab some pen & paper
Don't settle, try new things out
Thanks!
