Fuzzy sets are used in various fields. For those who have little knowledge on fuzzy set theory we find that improving usability of membership function identification method is really important. This paper aims to propose this new method improved in usability and precision, and then to verify the method through experiments. First, we propose the method to identify a trapezoidal membership function, BASE method (boundary asymptotic estimation method). The features of this method are ternary rating of membership grades, asymptotic estimation of boundaries of 1-level set and support set, and effective and recursive selection of elements using computers. Results from psychological experiments are showing that the BASE method is superior to the computerized fuzzy graphic rating scale both in usability for inexperienced users of fuzzy set theory and precision.
