The Mental Cutting Test were applied to engineers who were employed as mechanical designers by companies which were members of Japan Mechanical Design Industries Association. As a result, the mean score of engineers who have long years experience on mechanical design is significantly higher than that of rest. Moreover, the mean score of female engineers is significantly lower than that of male engineers.

In this paper, we propose the technique for automatically adding the Japanese-style animation like expression from sequential image. The speed-line that drew tracks of the moving object used and generated the geometric object in related work. However, there is no technique for drawing by extracting the moving object from sequential image. We define speed-line using two conditions : “drawing in tracks” and “line where the back of a present and past object is connected”. Our technique generated an effect based on the sequential image without a change in the background color. Our technique is conducted in four steps, region splitting by color, grouping region, tracing region, and generating speed-line. Our technique can be applied to some sequential images, and its effectiveness has been demonstrated.
