Skill, such as arts, sports and crafts, is regarded as a cycle that consists of the following three steps: recognition of objects, selection of appropriate action series and execution of the action. In arts and crafts, people produce works as a result of this cycle. Skill-learning environment should involve diagnosis-function providing appropriate advice for each step. This paper describes technique that is providing advice in real time when a learner learns recognition of drawing. To assist learners' recognition, we developed the sketch-area-dependent advising system that presents advice with voice for learners' drawing. The effectiveness of advice was confirmed through an experiment evaluating proposed technique.
