The stress is classified roughly into the eustress and distress. We have developed stress evaluation system using onomatopoeia for stress reduction. We focused on Image conversation used by LINE. Creating an image of onomatopoeia was introduced it into the system. The first purpose of this study was to develop of simple evaluation system using image conversation. The second was to evaluate the system and usefulness of production image. Fourteen male subjects were participated in the experiment using the system for 3 days. After that, they answered the system evaluation test of 17 items in 5-stages. As the result, the system has obtained a high average 3.58 rating however the average of two evaluation items was less than 3. This means that the system needs a more clear feedback and further development.
