Jun Xing, Li-Yi Wei, Takaaki Shiratori, Koji Yatani describe their system: Manual design is a form of art and a communication tool of great value, but complex. This is why we have designed a system that helps people create manual frame-by-frame animations. We have designed a minimal interface, we find the canvas and a handful of colors. When the designer starts drawing, our system analyzes the previous sketches and predicts how they could move in space. The interface can also recommend the already set drawings, by default.
