ABSTRACT
We describe a new sketching interface in which shape recog-
nition and morphing are tightly coupled. Raw input strokes
are continuously morphed into ideal geometric shapes, even
before the pen is lifted. By means of smooth and contin-
ual shape transformations the user is apprised of recognition
progress and the appearance of the final shape, yet always
retains a sense of control over the process. At each time t the
