HANDBOOK INPUT / OUTPUT SYSTEM, DIGITAL INK SHEET, INFORMATION INTAKE SYSTEM AND SHEET SUPPORTING INFORMATION INPUT

摘要

A handwriting input/output system that allows letters, characters and figures to be input by hand is provided easily and with low cost. The objective is to easily provide a handwriting input/output system with low cost, in which an imaging means captures and transmits the image of a medium provided with a writing area having a dot pattern that defines coordinate information and code information, dot pattern analysis means calculates trajectory information by storing the image data of the dot pattern and analyzing the code of the image data, trajectory recognition means recognizes the trajectory information of the letter, character, and figure traced on the writing area based on a change in the analyzed coordinate information, process instruction means transmits a process instruction based on the recognized information together with the trajectory information to information processing means, whereby a letter, character, figure and the like can be input by hand. Also, provided is a handwriting input and output system capable of inputting not only information of letters, characters, and figures but also related information thereto.
