Abstract:

Techniques are provided for hand drawing an animation motion path for an object to follow on a graphical user interface (GUI). The motion path may be drawn with a user's finger or drawing device, such as an Apple Pencil, by selecting a drawing tool (e.g., a freehand tool and/or straight line tool). A new motion path may be added to an existing motion path, such that the new motion path is an extension of the existing motion path. The new motion path may also be added to an end point of an existing motion path, such that the new motion path is a different segment of a motion path and is associated with a new key frame. A motion path segment may be split into additional segments with new key frames, reshaped using editing points, redrawn, and/or deleted from the overall motion path. In some embodiments, the actions applied to the object (e.g., motion path) may be indicated by an associated tray that provides editable context-specific properties related to the action.
