  • Patent number: 5867150
    Abstract: 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.
