Enabling collaboration in the sketching domain
… systems. Many problem domains, such as designing electrical circuits, developing flow charts, and modeling simple mechanical devices, rely heavily on the ability to produce sketches efficiently in order to bring out the most salient features. Engineers working in these domains usually rely on pen …
