Performance Effect of Matching Computer Interface Characteristics and User Skill Level

Abstract An experiment was conducted to see if matching user interface characteristics to user computer knowledge could improve user performance. User performance was measured by simulation game results, the extent of errors and user response time. Experiment subjects were tested to determine their level of computer knowledge using a pretested instrument. The subjects were randomly assigned to either a novice or experienced oriented interface version of a space manufacturing simulation. Results show that task performance (manufacturing profit) significantly increased when user interface characteristics were matched to user computer knowledge (e.g. novice interface to novice user). The relationship between interface match and user errors was marginally significant. The results of this study are important to software designers and practitioners purchasing software products.
