Computer aided drawing system based on prediction of drawing action

ABSTRACT

Computer Aided Design (CAD) systems are widely used recent years. In general, however, designers sketch product images by their own hands during early stages of designing. The authors aim to aid these freehand design by predicting and guiding designer's drawings using computers and a display-tablet. The computer estimates geometrical figures that the designer is drawing in real-time. The experimental results shows that the proposed system is effective for simple designing processes.
