Abstract: A workflow system for performing a process according to information input to an electronic form from an input screen displaying the electronic form, and inputting handwritten information of a corresponding paper form to the electronic form is disclosed. Based on screen formation data used for forming the input screen, paper layout information defining the paper form corresponding to the input screen is generated. The paper form is printed based on the paper layout information together with a form ID identifying the electronic form. An image of the printed paper form to which handwritten information is added is input. The handwritten information and the form ID are extracted from the image of the paper form input, converted to electronic handwritten information, and input to the electronic form corresponding to the extracted form ID.

Abstract: A pen includes a first speaker that outputs a first signal and a second speaker that outputs a second signal. The first and second speakers are located away from a tip of the pen at respectively different locations. The second signal is delayed with respect to the first signal by a time shorter than a cycle of the first signal. An interpolation time is set between the times of generation of the first and second signals. Interpolated positions of the first and second speakers at the interpolation time are estimated, and position of the tip of the pen is calculated from the interpolated positions of the first and second speakers.

Abstract: An image processing device is disclosed that includes an image reading unit to read a manuscript including image information and additional information related to the image information, an extraction unit to extract the image information and the additional information from manuscript image data of the manuscript, and a processing unit to perform processing on the image information based on the additional information.

Abstract: An electronic document creating apparatus includes a document information obtaining device that obtains and inputs document identification information put on a sheet document. The document identification information specifies an electronic document stored in a folder. The electronic document serves as an output source of the sheet document. An electronic document extraction device is provided to extract an electronic document based on the document identification information. A new document creation device is provided to create a new electronic document by combining at least two electronic documents extracted by the electronic document extraction device. The new electronic document is stored in a folder.

Abstract: A document processing system is disclosed that is capable of processing both fixed-format and unfixed-format hand written paper documents. The document processing system includes an encoding unit that encodes a sheet ID for identifying a hand written first document on a sheet to generate a coded sheet ID; a decoding unit that decodes the coded sheet ID; a document-sheet ID association unit that associates the sheet ID with a document ID assigned to a computerized second document; a printing unit that acquires the sheet ID and prints the coded sheet ID on the first document; a sheet ID management unit that manages the sheet ID; an information acquisition unit that acquires the sheet ID decoded by the decoding unit, and hand-written data from the first document on which the coded sheet ID is printed; and a process-sheet ID association unit that associates the sheet ID with a process ID of a process for processing the hand-written data acquired by the information acquisition unit.
