Abstract

The personal Electronic Book System invention replaces a standard handheld book with an electronic equivalent. The invention is sized and configured to be book size and to open like a book for use. When opened, the user sees two facing page-like touch-sensitive, display screens with black print on white background. Icons represent the electronically stored material, "artwork, audio clips, books, E-mail, faxes, games, magazines, movies, musical compositions, newspapers, photographs, software, video clips, etc.", which are selected by touching the icon. When a book, magazine, newspaper, or the like is selected, its table of contents is displayed and the user can then read page by page or go directly to a particular page by touching the selection listed in the table of contents. Closing the Personal Electronic Book automatically shuts down the device. Touching a page number before closing the Personal Electronic Book inserts a bookmark so that when the Personal Electronic Book is re-opened, the user is returned to the same page. New printed or multimedia material can be downloaded from a remote server, that is, "a bookstore", and old material, books read, etc., can be deleted to make room for the new material.

Description

~ CA 02231807 1998-0~-12 PERSONAL ELECTRONIC BOOK SYSTEM

TECHNICAL FIEL'D
The present invention relates to information and multimedia storage and display systems 10 and specifically to paperless books, personal electronic books, personal electronic communicators and readers, personal electronic message communicators, personal electronic facsimile commllnir~tors on-line computer database communicators, and downloadable computer database products such as artwork, audio clips, books, E-mail, faxes, games, magazines, movies, musical compositions, r.~ ,apel~, photographs, software and video clips.

BACKGROUND ART
Vast amounts of printed material are widely distributed in the form of printed books, magazines and newspapers. These traditional media are printed on paper with a page printed on each side of the paper so that when reading a book, magazine or newspaper, two pages of printed 20 material are exposed to the reader. These printed materials consume vast quantities of paper and also shipping resources to transport them to bookstores or newsstands for sale to the ultimate consumer, to libraries or to warehouses for storage. In recent years, virtually all commercially printed media are printed from computer-based databases and yet these same databases are only slowly becoming available to users of personal computers (PC). Even with the availability of book-25 like material displayed in page format on the PC, consumers have shown a very low acceptancelevel to reading from a computer screen. Readers want to hold and cradle the item they are read ing, view entire pages at once, and look down at their reading material.

Newsl~ap~ and magazines spend about lO0 million dollars a year producing electronic 30 editions of their publicalions More than 120 newspapers currently offer electronic editions.
Dozens of magazines covering a diversity of subjects are available in electronic editions The Wall Street Journal reported that an April, l995 survey of 650 newspapers indicated that 12 percent of these are already offerin~ on-line electronic editions and that 40 more newspapers expect to of~er eleclronic editions by the end of l995. A major deficiency of electronic editions of newspapers and 35 ma~,Jazines is that these editions typically bear little resemblance to the printed publications especially in terms of graphics, page layout and typography.

CA 02231807 1998-0~-12 With the accessibility and ready availability of the PC, accessing information stored in computer databases and in multimedia formats has transcended the computer mainframe and has been popularized in various media now available to the PC. As yet, this information and multimedia explosion has tailed to deliver a personal, dedicated electronic device that is as easy to S use or even as desirable to use as the common book, printed on paper and bound in a soft or hard cover. The present invention provides a personal, portable electronic book that overcomes these deficiencies.

The prior art which may be relevant to this invention is described hereinafter.
U.S. Pat No. 3,718,906 to Lightner discloses a method and apparatus for a computer controlled host to transmit customer selected sound (or v ideo) recordings stored on constantly running endless master tapes over AT~cT's p;ctu,ephone telephone lines to remote vending m~.~hin~c where the sound recordings are recorded onto cassettes and delivered to the customer.

The device can be adapted for particular uses such as hand-writing recognition or TV or radio receiving by plugging in special 35 purpose electronic cards. This disclosure describes a bat~ery-powered, handheld computer that uses a large, flat touchscreen display to replace a mechanical keyboard and that has the facilities to communicate with a remote host over telephone lines CA 02231807 1998-0~-12 U.S. Pat No. 4,649,499 ~o Sutton et al. discloses computer programs designed to emulate a three dimensional object such as a rotary card file or a hand calculator on a computer touchscreen.
Functions are performed by touching appropriate symbols on the touchscreen; for example, a knob to rotate the cards, a tab label to select and view a card. plus softkeys to perform other functions on 5 the cards. An emulation that puts up a functional calculator touchscreen display is also disclosed.
This disclosure describes the interaction between a touchscreen and the operation of a computer and software to present a display of information with softkey areas that are used to provide user control of the associated information or function.
U.S. Pat No. 4,682,161 to Bugg discloses a video display terminal connected via a modem 10 over a telephone line to a remote source for the purpose of acquiring and transmitting information.
This disclosure describes the logic circuits used to transfer digital codes to the terminal so that the data can be displayed on a raster scan display device in either normal of enlarged character size.
This disclosure describes cornm~ C;~ing over a telephone line via modem and transferring data to be displayed on a screen.
U.S. Pat No.4,855,725 to Fernandez discloses a simulated book that uses a battery-powered microprocessor with ROM for the program and RAM storage for data and a large LCD
screen to display up to 2 pages of information transmitted from a CD-ROM equipped PC over an attached infrared transceiver to a transceiver incorporated into the simulated book. The book uses a 20 touchscreen to display the data and to control paging through the material. The device automatically requests additional pages of information to be transmitted from the PC for storage in the book. The book can be taken with you for latter reading. Data storage is maintained by a battery powered RAM. An alternative version disclosed includes a keypad and a tactile pad switch for inputting requests for a particular page or to page forward or backward. The book displays a 25 single page at a time with the program automatically requesting pages of information to be transmitted from the PC to the book on the fly as the user reads or pages through the book.
