ABSTRACT
We take the intuition creation as a starting point in this research. First, the situation was investigated when child use traditional tools to draw pictures. The function of drawing system for children was defined according to spot observation, questionnaire interviews, opinions of specialized teachers. Second, by using the Usability Engineering the children’s demand was discussed when they operate different pointing devices. In order to control drawing function, the result from transformation and movement by the hand signal makes the invisible control interface of pointing device the most suitable document. Third, combination of vision sign rule and sign language and discussion with experts construct the gesture movement image. Finally, carrying on operation of drawing system by gesture movement and visual interface feedback and using technique of experiment confirm the system performance criteria. Also, we look for system design specifications and the correcting directions. At the same time, the subjective feeling of participants was thoroughly investigated. In the future, we provide the reference for company to develop the children drawing system.
