The document discusses different animation techniques used in interactive media, including persistence of vision, claymation, stop-motion, computer generation of frames and keyframes, onion skinning, and tweening. Persistence of vision creates the illusion of movement by displaying a series of images rapidly. Claymation involves moving plasticine objects between photographed frames. Stop-motion similarly manipulates objects frame-by-frame. Computer animation uses software to generate and manipulate individual frames and keyframes in layers over time. Onion skinning and tweening help animate objects by showing overlays of frames and generating motion between keyframes.
