A Sketch Recognition Scheme for Primary Geometry Education

Super Sketchpad(SSP) is a domestic software of dynamic mapping, providing powerful and rich functionalities for teaching and learning of geometry discipline in primary shools. Allusion to subject characteristics, this paper presents SPUI, a scheme for developing pen-based user interface. SPUI provides a more natural input interface for SSP. The SPUI gives a detailed description to the system architecture of pen-based user interface, expatiates upon all the component modules and mutual relationship of the system architecture. To demonstrate SPUI´s validity, we introduce the usage at last.
