  • the user first performs one of the following actions: turns on the device with the power switch (1) and inserts a data storage unit containing the required material in the media drive (2); or, turns on the device with a data storage unit already in the media drive; or, the power could be on and the user changes data storage units. Regardless, the device will automatically read the data storage unit with no further user interaction at this point. Each data storage unit will be produced so it will always automatically display a pre-defined first page on the viewscreen (3), which could be a title page, containing title, author, copyright data, publisher, etc. as required.
  • the second page accessed by the "Next Page” control (4), could display a Table of Contents and/or Index if required, (particularly essential for educational and research material).
  • the Table of Contents or Index will indicate the page number where data is located, and by pressing the "Find
  • EET Page control (5), the user activates the device to accept the numerical page identifier from the keypad (6) . It then locates the requested page on the data storage media, and relays it to the viewscreen for display.
  • Normal reading i.e. non-reference
  • the user presses the "Next Page” control (4) when finished a page, which prompts the device to locate and display the next sequential page.
  • a "Previous Page” (7) function is also provided, which prompts the device to locate and display the previous sequential page, as reading often involves reviewing something a few paragraphs back.
  • the "Find Page” (5) feature will be used.
  • Each page displayed will include an information line (9) at the top, in addition to the tex /data area (10), on the view-screen.
  • the dotted lines in Figure 1 represent where the data will appear, and will not be present on the screen.
  • the vertical arrow down from the dotted lines indicates that the text/data area continues to the bottom of the viewscreen (3) .
  • the information line will display both "hard” and “soft” data (see Figure 2).
  • Hard data (11) is defined as data that will always appear on each page displayed, i.e. page number, and perhaps title, author or other information, and will be on the left side of the information line.
  • Soft data is the information that depends on use of the "Find Page" function, and will appear on the right.
  • the soft data will consist of a message and input field (12) consisting of the following: "FIND PAGE NNNN”, (the NNNN representing the capability to accept four numerical values input from the keypad), which will appear on the information line when the "Find Page” control is pressed; or the message “NO PAGE NNNN”, which will appear if a page number higher than the actual number available on the
  • SUBSTITUTE SHEET data storage unit is input.
  • the text/data area (10), Figure 1 is where the actual text, data or graphics of the page being displayed will appear.
  • Pressing the "Find Page” control (5) prompts the device to accept the input of a numerical page identifier from the keypad (6).
  • the "Find Page” search activity will happen automatically after the input field (12), Figure 2, is filled. This will require “zero-filling” of page numbers less than 1000; i.e. to find page 267, input 0267; for page 29 input 0029; while any 4 digit page numbers will satisfy the criteria. This allows the use of the "Find
  • a character size adjustment switch (13), Figure 1, will allow the user to increase the size of the data being viewed, to provide for use by the visually impaired (Figure 2B).
  • Figure 2A illustrates approximate text size at 2,400 characters per display while Figure 2B shows the same text at approximately 800 characters per display.
  • the character size adjustment switch will instruct the device to divide each defined page into three sequential sections. The data characters in each one- third page will be expanded and reorganized to fill the screen when that section is accessed. With this design the page number would apply to all three enlarged sections, and use of the 'Find Page' and 'Find Placemark' controls would access the first section of that page.
  • the 'Next Page' and 'Previous Page' controls will access the next sequential section forward or reverse in this mode, regardless of whether the section had the same or a different page number.

  • the final capability which the device will provide is a placemark function, (i.e. a method of 'remembering' a particular page the user wishes to access the next time the data storage unit is used). This is accomplished by having a tiny area of memory reserved as each data storage unit is produced. The device software will store the present page identifier in this area, updating it each time a new page is displayed. The 'Find Placemark' (8) control will instruct the device to read this identifier from the data storage unit and display that page. This method ensures the placemark is held even when the data storage unit is removed from the device. Display of the Title, Table of Contents and Index will not update the identifier stored in the placemark area on the data storage unit. This allows the user to access a data storage unit, see the Title, Table of Contents and Index if required, and then access the page last displayed from a previous session using the 'Find Placemark' function.

  • the device will include one or more 'Visibility' controls (14), which will allow modification of some or all of the display attributes of; resolution, definition, contrast, brightness, colour and tint of the background and/or data displayed.
  • the device will also have an automatic power down capability, i.e. if no controls have been used within a specified period, the device will shut off. Since the placemark is held on the data storage unit, the minimal inconvenience will be outweighed by the saving in recharge requirements.
  • the combination cover/support stand/handle ( Figure 3) will function as follows:
  • SUBSTITUTE SHEET media drive are protected, and the handle (17) is in position for carrying.
  • the user releases the clasps (18) on the top, opens and rotates the cover/stand/handle (counter clockwise in Figure 3 views) and folds it under the device by means of the two hinged joints (19, 20).
  • the front hinged joint (19) allows the cover mechanism to fold, and the rear hinged joint (20) attaches it to the device.
  • the hinged support brace (22) is then folded out from the back of the device and inserted into one of several slots (23) in the front of the cover. The angle the device sits at depends on the slot chosen.
  • the dotted line (24) in 3B and 3C represent the surface the device is sitting on.
  • the rear hinged joint (20) will be spring loaded, which will cause the area between the hinged joints (21) to lie flat against the back of the device when the cover mechanism is open, as in 3B and 3C.
  • the cover/stand/handle is folded completely under as in 3C.
  • the process is reversed and the clasps on the top engaged, thereby putting the handle in position for transport and the cover in place for protection as in 3A.
  • the invention is not restricted to the embodiment shown herein, and encompasses the following alternative possibility.
  • the portable, electronic reading and reference device as described in this specification has a variety of potential application, design and functionality enhancements. Possible applications which the device would allow, other than those already specified are; the replacement of newspapers as they exist today with units of computer addressable storage media, portable unabridged encyclopedia and other large groups of documentation,
  • SHEET convenient recipe display, enhanced multiple text transport for students and greatly increased storage capabilities due to the size of the units of storage media as compared to books.
  • the design of the device could allow such enhancements as a printer port for the creation of hardcopy if required, and the incorporation of water-proofing, to allow reading and reference in environments potentially destructive to paper documentation (e.g. bath and shower, rain, etc.).
  • Possible additional functionality the device could provide is dynamic graphics (i.e. the capability of animated, moving pictures or illustrations to enhance reading and more effectively illustrate reference material).

Abstract

Le dispositif décrit constitue une variante par rapport aux livres et aux autres formats de présentation à base de papier. Il permet d'accéder et de récupérer du texte, des données et des graphiques dans des unités préalablement codées de moyens de stockage adressables par ordinateur, et de transmettre ces données à un écran vidéo monochrome ou couleur intégré. Les données sont stockées sur de petites unités préalablement préparées de moyens de stockage de données à volume élevé (p. ex. des disquettes de 3 1/2 pouce), qui sont chargées individuellement dans le dispositif en fonction des besoins. Des fonctions commandées par l'utilisateur permettent d'accéder à des groupes prédéterminés de données, p. ex. des pages, et de les afficher séquentiellement par défilement avant/arrière, par numéro de page, ou par la page spécifique qui était affichée en dernier sur des unités de stockage de données par une fonction de repère électronique. Les fonctions d'affichage offrent la possibilité d'augmenter la taille des caractères affichés sur l'écran, d'une utilisation du dispositif par les malvoyants, et comprennent des commandes permettant de régler les caractéristiques de visibilité (p. ex. résolution, contraste, couleur, nuance etc.). Le dispositif est protégé et maintenu par une housse et un support combinés, et il incorpore une poignée pour faciliter son transport. Le dispositif diffère des ordinateurs de bureau et des ordinateurs plus importants par le fait qu'il incorpore les améliorations suivantes: fonction de lecture seule, ne pouvant programmer ni être programmée; simplicité des commandes et du fonctionnement; et portabilité. Il diffère des ordinateurs portables par les améliorations suivantes: fonction de lecture seule, ne pouvant programmer ni être programmée; simplicité des commandes et du fonctionnement; et un coût moins élevé. Il diffère également des méthodes de sortie non électroniques de texte et de données sous forme d'imprimés et du papier ou autres par les améliorations suivantes: possibilité d'accéder aux données conservées sur des moyens de stockage de volume et poids sensiblement réduits par unité de données; durabilité; possibilité de modifier la taille du texte et des données; éclairage interne; commodité; et la possibilité de réduire la demande en pâte à papier et en papier qui porte atteinte à l'environnement.
