Appeal No. 97-1223 Page 2
Application No. 08/147,143
BACKGROUND
The invention at issue in this appeal relates to personal
digital assistants (PDAs). A user can store “electronic
books,” e.g., lists of telephone numbers, in a PDA. The
invention helps a user “navigate” through such a book. More
specifically, it allows him to determine where he is located
within the book, what other material is available in the book,
and how to get to other locations in the book.
Claim 1, which is representative for our purposes,
follows:
1. A method of controlling the display of an electronic
book on a display screen of a hand-held stylus-based computer
having a processor connected to the display screen, a memory
connected to the processor, one or more buttons, and a stylus,
the method comprising:
opening a book package which contains the electronic book
and which resides, at least in part, in the memory of the
computer;
displaying a view of a current page of the electronic
book on the display screen, the view including at least one
navigation button;
displaying a navigation dialog box on the display screen
when the navigation button is selected by interaction of the
stylus with the display screen, the navigation dialog box
having at least a bookmark button and a return to menu button;
