Definitions

  • Paper documents have an enduring appeal, as can be seen by the proliferation of paper documents in the computer age. It has never been easier to print and publish paper documents than it is today. Paper documents prevail even though electronic documents are easier to duplicate, transmit, search and edit.
  • Figure 1 is a data flow diagram that illustrates the flow of information in one embodiment of the core system.
  • Figure 10 is a diagram that shows a subset of the symbols shown in Figure 9 that self-define their vertical and horizontal extent.
  • a reader may capture some text from an article as an audio file by using microphone 310 as an acoustic capture port.
  • Logic 326 causes audio file to be stored in memory 328.
  • Logic 326 may also perform voice recognition or other post-scan processing on the audio file to convert it to text.
  • the reader may then upload the audio file (or text produced by post-scan processing performed by logic 326) to an associated computer via interface 316.
  • the printed document is a gateway to extra materials and functionality, access to such features can also be time-limited. After the expiry date, a user may be required to pay a fee or obtain a newer version of the document to access the features again.
  • the paper document will, of course, still be usable, but will lose some of its enhanced electronic functionality. This may be desirable, for example, because there is profit for the publisher in receiving fees for access to electronic materials, or in requiring the user to purchase new editions from time to time, or because there are disadvantages associated with outdated versions of the printed document remaining in circulation. Coupons are an example of a type of commercial document that can have an expiration date.
  • a scanning device for use with the described system will often be small, portable, and low power.
  • the scanning device may capture only a few words at a time, and in some implementations does not even capture a whole character at once, but rather a horizontal slice through the text, many such slices being stitched together to form a recognizable signal from which the text may be deduced.
  • the scanning device may also have very limited processing power or storage so, while in some embodiments it may perform all of the OCR process itself, many embodiments will depend on a connection to a more powerful device, possibly at a later time, to convert the captured signals into text. Lastly, it may have very limited facilities for user interaction, so may need to defer any requests for user input until later, or operate in a "best-guess" mode to a greater degree than is common now.
  • While component characters of a text fragment may be the most recognized way to represent a fragment of text that may be used as a document signature, other representations of the text may work sufficiently well that the actual text of a text fragment need not be used when attempting to locate the text fragment in a digital document and/or database, or when disambiguating the representation of a text fragment into a readable form.
  • Other representations of text fragments may provide benefits that actual text representations lack. For example, optical character recognition of text fragments is often prone to errors, unlike other representations of captured text fragments that may be used to search for and/or recreate a text fragment without resorting to optical character recognition for the entire fragment. Such methods may be more appropriate for some devices used with the current system.
  • a scanner will often communicate with some other device, such as a PC, PDA, phone or digital camera to perform many of the functions of the system, including more detailed interactions with the user.
  • the SimpleScanner does not have sufficient processing power to perform any OCR itself, but it does have some basic knowledge about typical word- lengths, word-spacings, and their relationship to font size. It has some basic indicator lights which tell the user whether the scan is likely to be readable, whether the head is being moved too fast, too slowly or too inaccurately across the paper, and when it determines that sufficient words of a given size are likely to have been scanned for the document to be identified.
  • the system can prevent others from using a device that is already associated with a scanner during the period (or session) in which the device is associated with the scanner. This feature is useful to prevent others from using a public kiosk before another person's session has ended.
  • the user scans a barcode on a monitor of a PC which s/he desires to use; in response, the system sends a session ID to the monitor that it displays; the user initiates the session by scanning the session ID from the monitor (or entering it via a keypad or touch screen or microphone on the portable scanner); and the system associates in its databases the session ID with the serial number (or other identifier that uniquely identifies the user's scanner) of his/her scanner so another scanner cannot scan the session ID and use the monitor during his/her session.
  • FIG. 6 is a diagram showing a scanning device that has an integrated highlighter and pen. It can be seen that scan device 600 contains both a highlighter 601 and a pen 602, which are optionally retractable.
  • Figures 8A-8D illustrate how two characters of an alphabet often have approximately the same * relative * shape in multiple fonts.
  • Figure 8A shows the letters "D", "C", and "L” in an Arial lower-case font
  • Figure 8C shows these letters in a Times New Roman lower-case font. Even though the fonts are very different and distinct, the relationship between these characters * within * a particular font are approximately the same.
  • Figure 10 is a diagram that shows a subset of the symbols shown in Figure 9 that self-define their vertical and horizontal extent. Each symbol of the subset 1000 is two boxes wide and two boxes high.
