In UX designing, we sometimes propose a new concept product or service, focusing on user experience value. In this case, it is desirable to conduct concept evaluation at an early stage to confirm the direction of development. However, the method to reasonably conduct a concept test at a stage when the product or service is not concrete enough remains unclear. In this study, we analyzed the effect of results from the differences in the expressions of the following 3 concept sentences: (A) expression showing only the experience value; (B) expression with usage scene in addition to the experience value; and (C) expression with function in addition to the experience value. As a result, we found that A could reasonably evaluate “the degree of matching the needs” and “novelty”, and that C could reasonably evaluate “sympathy”. In this study, therefore, we suggest a two-stage concept test method in which we first present only the experience value to evaluate the degree of matching the needs and then present the usage scene to evaluate sympathy.
