A free-hand drawing with simultaneous projection of predicted guideline

Figure 1 demonstrates a novel computer aided drawing system proposed by the authors. This system, which is called Hyperdraw, assists designers' drawing of sketches immediately and intuitively without disturbing their characteristic tastes of drawing and delicate feeling of drawing on a canvas. Hyperdarw shows its user suggested curves/lines by predicting his/her drawing action in real-time. Drawing of straight line, circle, parabola, and ellipse that are commonly used on early stage of designing is assisted by Hyperdraw's projecting of dynamically predicted guideline on the canvas. The user can follow the guideline or can ignore it, which makes users of Hyperdraw be able to draw beautiful straight line, circle, parabola, ellipse, with mixing their touches, quite easily.
