Abstract: A mobile device searches for electronic content. The mobile device captures an image from a rendered document, and searches for an electronic version of the image using characteristics of the image and using text within the contents of the image. The mobile device receives a result for the search based upon the image characteristics and the text within the context of the image.

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 among words of the sequence a word with which an action has been associated. The system then performs the associated action with respect to the user.

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 system for processing a visual capture operation as described. The system receives an indication of a visual capture operation performed from a rendered document. The indication specifies both a text sequence capture as part of the capture operation and a supplemental marking captured as part of the capture operation. The system determines an action to perform in response to receiving the indication, based both upon the text sequence specified in the indication and the supplemental markings specified by the indication.

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 portable device having scanning, imaging or other data-capture capability is described. In some cases, the portable device can indicate to the user when enough information has been captured to uniquely identify a source document. In some cases, the portable device calculates timestamps and location-stamps indicating when and where a data capture occurred. In some cases, the portable device is controlled by gestures. In some cases, the portable scanning device has associated billing and content/service subscription information.

Abstract: Embodiments of the disclosed innovations provide systems and methods for automatically locating and retrieving digital supplemental materials and counterparts of rendered documents. These systems and methods are especially useful when the provider or copyright holder of the digital document charges a fee for access to the digital materials. Some embodiments solve the technical problem of allowing a user to access restricted digital content associated with a rendered document via a search string captured from the rendered document. Some embodiments further provide automatic intermediation to gain access to protected digital materials.

Abstract: A system for processing a text capture operation is described. The system receives text captured from a rendered document in the text capture operation. The system also receives supplemental information distinct from the captured text. The system determines an action to perform in response to the text capture operation based upon both the captured text and the supplemental information.

Abstract: An action plan data structure for one or more selected rendered documents is described. The data structure contains information specifying an action to perform automatically in response to a text capture from any of the selected rendered documents.

Abstract: Character recognition is described. In one embodiment, it may use matched sequences rather than character shape to determine a computer-legible result.

Abstract: Systems and methods for quickly and easily getting information about, or included in, a paper document into a public or private digital page. One embodiment of an example system includes a scanner that generates scan information from at least a portion of a paper document and a processing system that receives the generated scan information from the scanner, accesses a database of digital documents, searches the database based on the received scan information, locates a digital document corresponding to the paper document, and sends either the digital content or a hyperlink to the digital content to a predetermined web page.

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 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.
