Graphic indexing system

摘要

A method and apparatus for selecting and indexing stored information for subsequent retrieval. The indexing system of the present invention indexes pages by storing a reference to a graphic segment of the displayed original page (instead of a copy of the graphic segment) as an index entry. Retrieval of the original page or image is accomplished by choosing from a listing of several categories of indexes, and then selecting an index entry displayed in the index gallery. The present invention provides a selection method using a lasso-tap gesture that allows the user to select a portion of the text for indexing (or other operations) without disrupting the natural handwriting action. Selection is accomplished using a closed (or nearly closed) curve followed by a recognized gesture within the closed curve. A local minimum established by the end points of the closed curve must fall within a specified range to identify the closed curve as a selection lasso. In one embodiment, recognized gestures for selection, enlargement, deletion and indexing are supported. Different segments from the same page or image may be compiled in the same index, or in different indexes. Indexing segments may be selected from any displayed page in the file, including spreadsheet pages or word processor pages, in addition to calendar pages and blank notebook pages.
