1C3-5 Identifying human property measurements for user-centered design based on user scenarios

抄録

User-centered design (UCD) gives extensive attention to human's physical, cognitive, and psychological characteristics at every stage of the product and service design process. Most of human property measurements currently available in UCD are limited to the physical body dimensions such as length or girth of a particular body part. This study aims to derive new concepts of human property measurements such as perceptional and cognitive characteristics from user scenarios. User scenarios were generated by combining factor levels, each belong to three factors such as user profile, user state, and environment. A total of 60 user scenarios were created and analyzed to derive relevant human property measurements, for example, sensory ability (visual/auditory/tactile), dynamic range of motion, and emotional/mental state, etc. The results demonstrated that various human property measurements could be efficiently derived from the user scenarios, without resorting to cost/time-consuming methods such as an observation and interview. The list of human property measurements derived in this study would be systematically measured and disseminated to be used for designing user-centered products and services in the further research.
