| Summary: | 碩士 === 國立成功大學 === 工業設計學系 === 103 === In recent years, the development of new products is fostered by technologic evolutions and there are more and more operating methods while designers get rid of the stale and bring forth the fresh ones. A good design needs to let users clearly understand how to operate a product’s interface, i.e., a good design must be based on a user-centered concept.
The starting point of this study is to investigate the relationship between operating interface designs and the user-centered concept. A case study was conducted on the operating interface designs of an induction cooker so as to conduct a comprehensive investigation on users’ experience and perception of the interface. There are five design principles of usability including visibility, mapping, feedback, constraint, and affordance for the operating interface design elements. A systematic usability scale (SUS) was improved by corresponding to the verification contents of the usability design so as to develop into a checklist of fifteen items.
Three types of induction cookers were selected for the case study in this study and subjects were invited to carry out experiments and fill in the improved SUS so as to determine the preferred design elements. According to the correlation of the usability design principles, eighteen verification items for an operating interface design were laid out. The weights of verification items of an operating interface design were determined and the operating interface design checklist of an induction cooker can be generated. Then various subjects were invited to conduct application tests based on the checklist and the results indicated that the verification items can effectively enhance their preference for a design element. New product operation interfaces can be designed by following the contents of the checklist.
The checklist proposed in this study for induction cooker operating interface designs allows designers to effectively quantify assessment results by the checklist. They can further understand the degree of excellence or inferiority for elements of a product’s operating interface design. This approach further provides a direction for follow-up corrections on an operating interface design so as to improve a product and make it easy for user operations.
