Computational support for sketching has a long and interesting history dating back to the early days of computing. Computational Support for Sketching in Design: A Review takes a brief look at the origins and history of the subject before going on to survey the literature from a wide variety of sources on modern sketch based design tools. It first describes the practical basis of sketching - why people sketch, what significance it has in design and problem solving, and the cognitive activities it supports. It goes on to survey computational support for sketching, including methods for...
