`PERSONAL ELECTRONIC BOOK SYSTEM
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention relates to information and multi—
`media storage and display systems and specifically to paper-
`less books. personal electronic books. personal electronic
`communicators and readers. personal electronic message
`communicators. personal electronic facsimile
`communicators. on-line computer database communicators.
`and downloadable computer database products such as
`artwork. audio clips. books. E—mail. faxes. games.
`magazines. movies. musical compositions. newspapers.
`photographs. software and video clips.
`2. Description of the Prior 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 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-er material displayed in page format on the PC.
`consumers have shown a very low acceptance level to
`reading from a computer screen. Readers want to hold and
`cradle the item they are reading. view entire pages at once.
`and look down at their reading material.
`Newspapers and magazines spend about 100 million
`dollars a year producing electronic editions of their publi-
`cations. More than 120 newspapers currently offer electronic
`editions. Dozens of magazines covering a diversity of sub—
`jects are available in electronic editions. The Wall Street
`Journal reported that an April. 1995 survey of 650 newspa-
`pers indicated that 12 percent of these are already ofl‘ering
`on-line electronic editions and that 40 more newspapers
`expect to offer electronic editions by the end of 1995. A
`major deficiency of electronic editions of newspapers and
`magazines is that these editions typically bear little resem-
`blance to the printed publications especially in terms of
`graphics. page layout and typography.
`With the accessibility and ready availability of the PC.
`accessing information stored in computer databases and in
`multimedia formats has transcended the computer main—
`frame and has been popularized in various media now
`available to the PC. As yet. this information and multimedia
`explosion has failed to deliver a personal. dedicated elec-
`tronic device that is as easy to 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.
`
`US. Pat. No. 3.718.906 to Lightner discloses a method
`and apparatus for a computer controlled host to transmit
`customer selected sound (or video) recordings stored on

`display alphanumeric characters and graphics. Any area
`touched on the screen is identified by its coordinates. The
`device can be connected to a remote host computer via an
`acoustic coupler and a telephone line. The device can be
`adapted for particular uses such as hand-writing recognition
`or TV or radio receiving by plugging in special purpose
`electronic cards. This disclosure describes a battery-
`powered. handheld computer that uses a large. flat touch-
`screen display to replace a mechanical keyboard and that has
`the facilities to communicate with a remote host over

`puter 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 the cards. An emu-
`lation that puts up a functional calculator touchscreen dis-
`play is also disclosed. This disclosure describes the interac-
`tion 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.
`
`US. Pat. No. 4.682.161 to Bugg discloses a video display
`terminal connected via a modem 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 com-
`municating over a telephone line via modem and transfer-
`ring data to be displayed on a screen.
`US. Pat. No. 4.855.725 to Fernandez discloses a simu-
`lated 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 trans-
`mitted from a CD-ROM equipped PC over an attached
`infrared transceiver to a transceiver incorporated into the
`simulated book. The book uses a 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 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.
`U.S. Pat. No. 4.918.632 to York discloses a battery-
`powered. portable touchscreen computer designed with a
`multitude of holes along one edge so that the computer can
`be transported in a 3-ring binder or the like.

`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 a white background. Icons represent the electronically
`stored material and user-selectable functions. 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 page
`number of the desired selection as listed in the table of
`contents. Closing the Personal Electronic Book automati-
`cally shuts down the device. Additional “printed” or multi-
`media material can be downloaded from an remote server.
`that is. a “bookstore.” and old material. books read. etc.. can
`be deleted to make room for the new material. The only
