A learning support system for beginners in pencil drawing

A picture is one of important research subjects to make our life spiritually rich. Most studies on pictures, however, only propose some substitute functions of actual drawing or painting materials. There is no system that evaluates pictures drawn by users and gives advice about them. We propose a learning support system of beginner's pencil drawing that is the basis of pictures. Our system receives a motif data set and a user's sketch image, and returns advice to the user. The processing is composed of the four functions: feature extraction of motifs, feature extraction of sketches, error identification, and generation and presentation of advice. We developed and experimented a prototype system limited to treat a basic motif and principal advice. As a result, the validity of the proposed system was confirmed.
