Abstract
Real time digitization of handwritten text and integration of digital recordation of handwritten text with traditional paper-based record making systems is achieved with a recording unit which may record a sequential data stream of strokes and associated events. The data stream may be stored in the apparatus and processed in accordance with various applications. Recordation of handwritten strokes may be accompanied by automatic detection and recordation of predefined events, and by user invoked generation of events. Recorded handwritten text may be processed to produce character strings or image data for text recorded in conjunction with predefined events.
