Using Normans modelSome systems are harder to use than others
Gulf of Executionusers formulation of actions actions allowed by the system
Gulf of Evaluationusers expectation of changed system state actual presentation of this state

Abowd and Beale frameworkextension of Normantheir interaction framework has 4 partsuserinputsystemoutput
each has its own unique language interaction translation between languages
problems in interaction = problems in translation
Vermelding onderdeel organisatie
Using Abowd & Beales modeluser intentions translated into actions at the interface translated into alterations of system state reflected in the output display interpreted by the user
general framework for understanding interactionnot restricted to electronic computer systemsidentifies all major components involved in interactionallows comparative assessment of systemsan abstraction
