User Interface examples

The good, bad and ugly

UI frustrations…grrrrrr! zThe engineer who founded DEC confessed he couldn’t heat his coffee in the company's microwave. zCan you use (program) yVCR yDigital watch yWater facets

Usability Design Implementation Evaluation

zAffordances zAffordances-strong clues as to use zMappings the controls and their result in the real world zFeedback- what action has taken place zConstraints- constraints the user

Affordances zAffordances refers to the perceived and actual properties, esp wrt how it is used or applied zAffordances provide “strong clues” to the operation of things

Mappings z Mappings refers to the relationship between two things zEg, control and movement ySteering wheel yDoor handle

Visibility (feedback) zAllow the user to be informed zShow him the state ydid I set the watch correctly? ycan I see the elevator in its shaft? zIs the tape in correctly? Is it engaged

Conceptual Model zScissors yAffordances - insert fingers into holes yConstraints - the size of each hole zYou can figure out how to use scissors because the operating parts are visible and understandable.

Guidelines for Design zProvide a good conceptual model yallows users to predict consequences of actions ycommunicates the system to the user zMake things visible yrelations between user’s intentions, required actions, and results should be xsensible xconsistent xmeaningful (non-arbitrary)
