ABSTRACT
Sketch-n-Stretch lets novices quickly and easily create 2D animations. The system has a seamless two-layer drawing interface that supports cutouts using a whiteboard metaphor. Cutout animations serve as building blocks to help users construct sophisticated animations. While manipulating cutout animations, users can draw and write text to create effects—such as articulated figures, multiple motions, and image objects—that have been difficult with previous sketching approaches. An intuitive timeline interface employs visually integrated motion cues and supports several traditional animation effects. Novices positively evaluated Sketch-n-Stretch's effectiveness in creating object motions, compared to an existing sketching tool. They also used its advanced features to animate complete stories. This video demonstrates the Sketch-n-Stretch tool for making sketch-based animations.
