In this paper, we propose a user experience evaluation method called “Experience Feedback Evaluation (EFE)”. It expresses a subject's subjective experience using a curve based on the video which recorded the situation of task operation. We performed a trial evaluation about the validity of EFE method. Trial evaluation was carried out to university students who are studying the design and collected the questionnaire of 35 samples. As a result, from a subject’s position, it shows that it is able to express subjective experiences and emotions accurately. On the other hand, validity was shown from the Investigator's position.
