Abstract

A method for controlling a screen display of an electronic book. The contents of the book are displayed on a screen of the computer system as pages with which the user interacts by a pointer such as a pen or stylus. The content engine performs various functions including one or more of the following: (1) creating page displays for content of the book, (2) providing a navigation interface for identifying material in the book and moving to desired locations, (3) finding character strings located within the book, and (4) accepting handwritten information on pages of the book. The electronic book includes a "bookmark" button which when selected displays a bookmark icon and inserts a bookmark in the book at the page that is currently displayed. Thereafter the user can close the book or move to another page and automatically return to the marked page by selecting the bookmark icon. The user can also move to other pages by scrolling with scroll keys or other navigational devices such as tables of contents browsers and menu pages which are provided on the computer system.

Claims

1. A method of processing handwriting written with a pointer on a screen display of a pointer-based computer having a processor connected to the screen display, a memory connected to the processor, a pointer, contents of an electronic book, and one or more buttons, the method comprising:

displaying a view of a current page of the book on the display screen;

recognizing handwriting as one or more character strings when said handwriting is written in handwriting recognition fields displayed on the screen display, the one or more character strings being used to identify at least one location within the book;

displaying handwriting written on the current page of the book after a mark-up button has been selected; and

hiding all handwriting and associated text written with said pointer on the current page when the mark-up button is re-selected.

2. The method of claim 1 wherein the handwriting written on the current page is hidden from view when a new current page is selected.

3. The method of claim 1 wherein the handwriting recognition fields include a page number recognition field and wherein the current page is changed to a page having a page number written in the page number recognition field.

4. The method of claim 1 wherein the handwriting recognition fields include a find field and character strings written in said find field are searched in records residing, at least in part, in the memory.
