Getting the timing and dynamics right is key to creating believable and interesting animations. However, using traditional keyframe animation techniques, timing is a tedious and abstract process. We present Dragimation, a novel technique for interactive performative timing of keyframe animations. It is inspired by direct manipulation techniques for video navigation that leverage the natural sense of timing all of us possess. We conducted a user study with 27 participants including professional animators as well as novices, in which we compared our approach to two other interactive timing techniques, timeline scrubbing and sketch-based timing. Dragimation is comparable regarding objective error measurements to the sketch-based approach and significantly better than scrubbing and is the overall preferred technique by our test users.
