  • Rapid prototyping is an efficient method to evaluate the usability of electric home appliances. However, the use of rapid prototyping method in usability tests has not been sufficiently validated. The purpose of this study was to validate computer-generated prototypes whether they can replace real products in usability tests. The control-display panel of a refrigerator was selected for this study. Sixteen female subjects participated in a between-subjects experiment: Eight subjects of them used the real refrigerator while others used the computer-generated prototype of the refrigerator. The difference between the refrigerator and the prototype was analyzed in terms of task failure rate, task completion time, and the number of buttons pressed for three typical tasks: clock setting, selecting an operation mode for refrigerating room, and selecting an rapid freezing mode. The results of a non-parametric statistical test showed that the prototype was not significantly different from the real refrigerator. Therefore, the rapid prototyping technique can be applied to the usability tests for the simple electric home appliances such as the refrigerator.
