Abstract: A system for determining viewership of articles or ads in printed publications and using the determined viewership to determine author compensation, ad rates, or other historical or demographic related information is described. The system receives text capture information of portions of a number of rendered documents that is generated by capture devices operated by a number of users. The system searches digital content using the received capture information and determines a readership value for components of the rendered document based upon the search.

Abstract: A facility for storing a text capture data structure for a particular user is described. The data structure comprises a number of entries. Each entry corresponds to a text capture operation performed by the user from a rendered document. Each entry contains information specifying the text captured in the text capture operation.

Abstract: A system for processing text captured from rendered documents is described. The system receives a sequence of one or more words optically or acoustically captured from a rendered document by a user. The system identifies an electronic version of the rendered document and associated an action. The system then performs the associated action with respect to the user.

Abstract: A handheld optical scanner and/or memory device for capturing images of text from a rendered document is described. The handheld device may include a data storage component, a scanning component configured to capture text from rendered documents, a power storage component, and a universal serial bus port configured to receive and store data from a computing device and transmit data to the computing device.

Abstract: A register interest system receives from a potential acquirer of assets an indication that the potential acquirer is interested in acquiring rights in a specific asset that is not currently on the market. The register interest system stores indications that the potential acquirers are interested in specific assets. When a notification criterion has been satisfied, then the register interest system notifies the owner of the specific asset that one or more potential acquirers are interested in acquiring rights to that asset. The owner and a potential acquirer can then negotiate the purchase of the rights.

Abstract: A facility for navigating an electronic document is described. The facility receives user input selecting a portion of the content of a rendered document that constitutes a sentence fragment. In response to receiving the user input, the facility identifies an electronic document contained in a corpus of electronic documents, the identified electronic document containing the selected document portion. In response to receiving the user input, the facility further identifies a position within the identified electronic document at which the selected document portion occurs.

Abstract: A facility for initiating a purchase is described. The facility receives a text sequence captured by a user from a rendered document using a handheld text capture device. The facility identifies in the received text sequence a reference to a distinguished product. In response to identifying the reference, the facility presents to the user an opportunity to place an order for the established product. If the user accepts the presented opportunity to order the distinct product, the facility orders the distinct product on behalf of the user.

Abstract: A device identifier is scanned with a portable scanner and communicated to a service provider. The service provider associates the device with the portable scanner. Information is scanned from a printed source and communicated to the service provider and subsequent information is received in response at a device identified by the device identifier. In some embodiments, a communication session identifier is scanned with a portable scanner and communicated to the service provider rather than (or in cooperation with) the device identifier.

Abstract: Information is scanned to a scanner memory. A user of the scanner is signaled when sufficient information has been obtained to determine at least one action associated with the scanned information.

Abstract: Techniques for determining the content of a document fragment based at least in part on its digest are described herein.

Abstract: Information corresponding to a sentence or less of text is scanned from a rendered document and converted to text. The text is communicated to a search engine. Electronic content corresponding to the rendered document from which the text was scanned is identified from the search engine results.

Abstract: There is provided a screen multiplexor for processing graphical display data and an associated distribution method. A plurality of graphical display data streams is received at the multiplexor, processed and directed to one or more network-connected display devices. The network is a general purpose data network and may be wireless. The directed data streams can be spatially multiplexed, temporally multiplexed, and/or multiplexed in such a way that data from one stream is overlaid on data from another stream. The distribution method and screen multiplexor thus allow a flexible relationship between the number of screens and the sources of the information to be displayed thereon.

Abstract: A system for interactive paper is described. Data fragments are captured at locations in a rendered document. A digital version of the document is optionally located. Markup data applied to the capture creates a rich set of interactions for the user. New models for publishing documents and new document-related services are described.

Abstract: A device for capturing rendered text is described. The device incorporates one or more visual sensors that receive visual information as a part of capturing rendered text. The visual sensors are collectively capable of capturing both text that is permanently printed on a page, and text that is displayed transitorily on a dynamic device. The device further incorporates a visual information disposition subsystem for disposing of visual information received by the visual sensors. The device further incorporates a package that bears the visual sensors and the visual information disposition subsystem, and is suitable to be held in a human hand.

Abstract: A facility for securing text captured from a rendered document is described. The facility receives data including an encryption of text captured from a rendered document. The facility decrypts the captured text included in the received data.
