KSketch

This paper explains and evaluates the features of an application KSketch, a informal 2D animation sketching system. It was developed to help novices create wide range of animations in a very less time. The research starts off with interviewing of animators and non-animators. The interviews confirmed the importance of informal animation tool. The researchers came up optimization technique to shortlist the features that need to be supported from the list of features that was made after analyzing users interest. The selected features are Translate, Scale, Rotate, Set Timing, Move Relative, Appear, Disappear, Trace, Copy Motion, and Orient to Path. Repeat Playback and Copy Object also have been added.

The interface of K-Sketch has three parts: a tool bar on top, a drawing canvas in the center, and time controls on the bottom. Physical "Alternate" button is used to alternate between modes.

There is no difference between recording and replaying in K-Sketch - edits to a playing animation are recorded and this means that all objects move simultaneously when time advances.

My thoughts: This is a great sketch recognition application whose use case is spread across domains. If the sketch recognition could add beautification also to this it would add a great value.
