A fast, simple algorithm for recognizing hand drawn geometric shapes is presented and evaluated. The algo- rithm recognizes (without regard to size) rectangles, ellipses, circles, diamonds, triangles, and lines. Each shape may consist of multiple strokes as long as they are entered without pauses. A pen-based graphic diagram editor employing this algorithm was developed on GO's PenPoint operating system. The editor will be part of a pen-based notebook system for teaching math to school children. The recognition algorithm was evaluated by ten subjects drawing a total of 200 shapes. It achieved a recognition rate of up to 98Y0. |
