First of all, some context
MOBILE DESIGN
inspiring new ways of design and development
Antony Ribot, CEO, Ribot
O2 Litmus - 12.12.2008

The user-centered developer
A DIFFERENT WAY OF THINKING
develops with the user in mind
a bridge between designer and developer
not a role for every developer
does not replace traditional UX expert

Constraints of mobile
But which is most important?
form factor battery
network latency context
input mechanism
memory
computational power

Context of use

Time for a snack...
DATA-SNACKING
small snippets of info
30-60 seconds
simple, but repetitive
regular

Re-use learnt behaviours
Re-use interactions inherent in the device
Minimise the number of surprises
soft key positions colour
menu navigation tone of voice

It’s all about the subtleties
Fewer options = simple and more effective
interface
Polish makes the UX and app stand out

Working around the 3G icon

Reward-based exploration
FOCUSING ON THE KEY FEATURE AND DOING IT WELL
keep it as simple as possible (the hard part)
1.allow the user to play within safe boundaries
2. user’s comfort increases
3. sense of exploration increases
4. discovery of features almost by accident
