Document Type and Number:
Japanese Patent JPH06505102
Kind Code:
A
Abstract:
A computer-based system for displaying all, or at least many pages of, a document, and including means for scrolling through the document for purposes such as browsing or editing. Most of the display shows text in a "greeked" form with one line of pixels representing one line of text. The greeked form, although illegible, shows shapes of text in the document by indicating the presence or absence of text. Two windows of legible text appear as if two bar-type magnifying glasses were placed over the illegible greeked text. A window may be moved to a new location by touching a stylus to a digitizing tablet (or by clicking a mouse) or by dragging with the stylus (or mouse). When the two windows are adjacent, they become latched and can be moved as one large window. Words of special significance (e.g., embedded labels or search results) can be displayed as legible tags wherever they appear, in the greeked text as well as in the legible text. The greeking is arranged to produce a checkerboard of pixels, that appears as gray, permitting black tags to stand out clearly. Because the tags appear throughout the display at locations corresponding to their locations in the document, they can add significantly to the context presented by the greeking, permitting the user to become oriented and to locate desired portions of the displayed document. Further, tags can permit a user to quickly ascertain the locations and significance of search results.
