The program is used the way that a subject inputs one's subjective feelings about an evaluation item presented with freehand drawing by using the mouse or pen tablet. It is possible to evaluate an item by a vague feeling and the method of drawing is free. There are few limitations or a prescribed standard and the subjects express their thoughts in drawing. The area ratio of each circle is shown as a pie chart and the area of a drawn circle is counted automatically at the same time. It is possible not only to modify a drawn circle's transparency, the thickness of a line, color and size but also to adjust and compare with other circles after evaluating. By visualizing the conceptual model as a circle with freehand drawing, it has a wide range of applications such as a personnel evaluation, a suffering evaluation and a product evaluation.
