Reduts in rough set theory was used as the new trial in this research. As a case, we designed 24 kinds of interface for a ticket vending machine. And, we made 12 subjects evaluate them about "the easiness to use", "the easiness to understand", and "time". Reducts of the good evaluation about each of three items were defined by rough set theory. We thought that combination of these reducts would be efficient design answer for developing the machine, on the basis of the hypothesis, we got three kinds of design answer.
