Human

factors design11!dentify the ob"ecti#es of

human factors design

Effectiveness (completeness and accuracy)

Efficiency(speed and effort), eg bottle opener

Engagement(pleasantness and satisfaction), shop design

Error tolerance(error pre#ention and error reco#ery),parachute

Learnability(predictability and consistency), remotecontrol

$with which acti#ities can be carried out and how human#alues, for e%ample, &uality of life, impro#ed safety,reduced fatigue and stress, increased comfort le#elsand "ob satisfaction, are enhanced

aspects of o!"ecti#e in car design

ontrols should be #isibleand it should beob#ious how theywork They should

con#ey the correctmessage, for e%ample,with doors that needto be pushed, thedesigner must pro#ide

signals that indicatewhere to push

eedback is the pro#ision ofinformation, for e%ample, anaudible tone to a user, as a resultof an action The tone on a

telephone touchpad or the clickof a key on a computer keyboardpro#ides feedback to indicatethat a key has been pressed The*egg timer+ icon on a computer

screen tells the user that anaction is being undertaken

apping relates to thecorrespondence betweenthe layout of the controlsand their re&uired actionor e%ample, the layout

of the controls on acooker hob can takead#antage of physicalanalogies and culturalstandards to facilitate a

user-s understanding ofhow it works

Affordance is the property ofan ob"ect that indicates howit can be used .uttonsafford pushing, and knobsafford turning n a door,handles afford pulling,whereas push plates affordpushing onsider how theuse of a handle on a doorthat needs to be pushedopen can confuse users, andhow in an emergency thismight impact on safetyconsiderations

conflict with other design aims

E%amine the notionof optimum

compromise and

consider cost,form, function,

which may bemore important
