Introduction
K-Sketch is an animated sketching system, a tool that aims directly at one of the main purposes and uses of modern pen based interfaces, drawing and animation. The focus of the work is not only to build a tool that makes animation simpler and easier, but also to develop and refine interaction techniques for sketch workspaces. In a user study comparing K-Sketch and PowerPoint in an animation task, it was found that the users were able to learn to use K-Sketch much faster, and generally felt that K-Sketch require much less cognitive load.
Discussion
Frankly it is a little bit surprising that they compared creating animations between K-Sketch and Powerpoint. While powerpoint can do animations, it is well known that Microsoft products usually require a high cognitive load and are not particularly easy to use. Additionally it seems that an actual animation program would be a better comparison, such as Flash or something like it. Still I expect the results would have been very similar, because the controls of K-Sketch seem well thought out and do not overly crowd the interface.
In other news the manipulator tool used in K-Sketch looks very similar to the manipulator tool in Prezi (or vice versa rather).
