Stresses are roughly classified into distress and eustress. However the method to reduce distress is to receive a counseling, more convenient stress evaluation system without counselor is needed. For this reason, a stress evaluation system using onomatopeias was developed without reducing user's distress. In this study, the improved stress evaluation system using onomatopeias was developed and evaluated. Twenty male subjects, with their ages from 21 to 25, were participated in the three-day experiment using both the previously developed system (system A) and the improved system (System B). After that, subjects answered a 5-grade system comparison test including 10 evaluation items. Afterward, subjects selected system A or system B, and used the selected system more for one week. One week later, subjects answered another system evaluationtest including 7 evaluation items. The results showed that "The more excellent system is system B than system A" was majority. However, in the usability evaluations system A was better than system B. That is, it is needed to improve more usability.
