Abstract
Abstract An electric device, such as an electronic book, retrieves information from a memory and displays the information. A matrix array of sensors associated with the display can be actuated by a user to designate particular portions of a displayed page. In response to the designations, flags are stored identifying the designated portions, and the appearance of the portions on the display is modified to visually highlight the portions. The page including the designation information can be immediately retrieved and displayed at a later time in response to a user instruction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
An electric device comprising: a reproducing device for reading information from a first memory; a display means for visualizing said information; a temporary memory for temporarily storing data supplied thereto from said first memory where the amount of data which can be stored in the temporary memory is greater than the amount of data which can be displayed by said display means; a matrix array of sensors associated with said display means which can be actuated by a user to designate particular portions of a displayed page; emphasizing means connected to said temporary memory and said display means for receiving said user designations, for storing flags identifying the designated portions, and for modifying the appearance of said portions to visually highlight said portions during display on the display means; and reference retrieving means connected to the display means for receiving a user instruction to recall a selected page of text containing said designated portion and for causing immediate retrieval and display on the display means of the previously designated information.
