The aim of this research was to develop a usability evaluation model based on customer sensation using quality function deployment (QFD), which evaluates the relationship between consumer sensation and usability among the physical design factors of dishwashers. Four aspects of the evaluation model were analyzed with QFD: overall sensation factors, detail sensation factors, usability evaluation factors, and physical design factors of products in 3 sequential processes. The sensation evaluation factors and the usability evaluation factors were created from the results of the sensation and usability tests. Moreover, experts and manufacturers were involved in selecting the physical design factors. With the evaluation model using these 4 aspects, physical design factors influencing user sensation were generated. These factors were Label Icon, Rack Size, Shape of Knob, and LCD size. In addition, the degree of influences was tested and design guidelines derived from the final physical design factors were generated.
