Device, a program and a system for managing electronic documents

Abstract

A device for recording positions within an electronic document and capable of recreating those recorded positions afterwards even if the electronic document has been changed to some extent. An index data creation unit in an information terminal creates index information for a page to display from the electronic document, and records it along with time information in an index database. When a time is specified, the index data search unit searches the index database for index information recorded near that time, and identifies the page position of that electronic document from the searched index information. A data display unit displays the beginning of the electronic document at the identified position. The information terminal is capable of managing information by linking electronic data from handwritten information written on paper with a digital pen, with the display page the electronic document by utilizing a stroke set database and a pen data processor.
