Donald Normans modelSeven stagesuser establishes the goalformulates intentionspecifies actions at interfaceexecutes actionperceives system stateinterprets system stateevaluates system state with respect to goal

Normans model concentrates on users view of the interface


execution/evaluation loop

user establishes the goalformulates intentionspecifies actions at interfaceexecutes actionperceives system stateinterprets system stateevaluates system state with respect to goal


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


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

interaction stylesdialogue computer and user

distinct styles of interaction

See Casus MKT 1 in1810


WIMP InterfaceWindowsIconsMenusPointers

or windows, icons, mice, and pull-down menus!

default style for majority of interactive computer systems, especially PCs and desktop machines


*

elements of the wimp interfacewindows, icons, menus, pointers+++buttons, toolbars, palettes, dialog boxes also see supplementary material on choosing wimp elements


Pointersimportant componentWIMP style relies on pointing and selecting thingsuses mouse, trackpad, joystick, trackball, cursor keys or keyboard shortcutswide variety of graphical images

Experience, engagement and fundesigning experiencephysical engagementmanaging value


Experience?home, entertainment, shoppingnot enough that people can use a systemthey must want to use it!

psychology of experienceflow (Csikszentimihalyi)balance between anxiety and boredom

educationzone of proximal developmentthings you can just do with help

wider ...literary analysis, film studies, drama
