FIELD: physics, computer engineering.SUBSTANCE: invention relates to a handwritten input/output system which facilitates handwritten input of letters, symbols and figures. The handwritten input/output system includes: a medium which comprises an input area, on at least a part of or a plurality of areas of the medium, formed with a dot pattern which repeatedly defines coordinate information and code information; an imaging unit which images the dot pattern of the input area; a dot pattern analysis unit which stores the image data of the dot pattern imaged by the imaging unit into a storage device and analyses a code of the image data to obtain trajectory information including the coordinate information and the code information; and an information processing unit which processes the trajectory information, where at least a part of the code information defines the input area.EFFECT: easy handwritten input/output.73 cl, 80 dwg |
