DonaldNorman’s Principles for Transforming Difficult Tasks into Simple Ones7
1. “USE BOTH KNOWLEDGE IN THE WORLD AND KNOWLEDGE IN THE HEAD””
2. “SIMPLIFY THE STRUCTURE OF TASKS”
1.Keep task the same, but provide mental aids
2.Use technology to make the invisible, visible
3.Automate but keep the task the same
4.Change the nature of the task
3. “MAKE THINGS VISIBLE: BRIDGE THE GULFS OF EXECUTION AND EVALUATION”
4. “GET THE MAPPINGS RIGHT”
5. “EXPLOIT THE POWER OF CONSTRAINTS, BOTH NATURAL AND ARTIFICIAL”
6. “DESIGN FOR ERROR”
7. “WHEN ALL ELSE FAILS, STANDARDIZE…”
User Experience Myths
EVERYTHING SHOULD BE ACCESSIBLE IN 3 CLICKS
“When users find what they want they don't complain about number of clicks”
PEOPLE WILL LEARN HOW TO USE OUR SOFTWARE
But not when there are better alternatives available ...
DESIGN HAS TO BE ORIGINAL
But not at the cost of becoming unusable ...
THANKS!@davidgeerts
