碩士 === 國立臺灣科技大學 === 工業管理系 === 107 === Based on previous IoT UI evaluation project, the need for a more efficient mental model measurement tool in UX research practices was identified, and concept mapping was considered the ideal candidate. Concept mapping is a kind of cognitive structure presentation that reflects the person’s mind by concept nodes and relationships between, which matches prior observations and meets practical needs. To validate the method and corresponding objectively-calculated closeness index as the similarity parameter, the subject-perceived similarity was utilized to measure the criterion-related validity, indicating a moderate correlation between the two (r = 0.513, p < .01). Next, the two variables than served as the response (y) in fitted regression models, for further contributory factor inspection and comparison. As a result, subjective similarity reflects mainly the higher-level graphical features and subject’s background knowledge, while the other grasp all aspects and local graphical features. In conclusion, concept mapping possesses many advantages for it being flexible, adaptable, economical, automatable, and reliable as a mental model measurement and assessment tool. If designed properly, the method is capable of being applied for various purposes as well as across design development stages.
