A system and method for automatically changing the operation of a mobile device in response to a presence of information is described. In some examples, the system determines an information capture device is proximate to text, automatically changes operation of the capture device to a certain mode, captures the text, and performs an action associated with the captured text.

Automatically capturing information such as capturing information using a document-aware device

A hardware, firmware, and/or software facility ('facility') for providing information relevant to rendered documents is described. In some embodiments, the facility identifies multiple versions of an electronic document corresponding to a rendered document captured by a capture device. The facility may then provide a person utilizing the capture device with various ways to interact with one or more versions of the electronic document. In some embodiments, the facility determines that use of a rendered document is restricted, such as by copyright, to some degree. The facility may then offer the person the option to obtain unrestricted use of the rendered document. If the person accepts, the person obtains the right to store captures of the rendered document. If the person declines, the facility automatically discards captures of the rendered document. In some embodiments, the facility may automatically purchase rights to restricted-use rendered documents based upon the person's predefined criteria.

Performing actions based on capturing information from rendered documents, such as documents under copyright

A system and method for automatically providing content associated with captured information is described. In some examples, the system receives input by a user, and automatically provides content or links to content associated with the input. In some examples, the system receives input via text entry or by capturing text from a rendered document, such as a printed document, an object, an audio stream, and so on.

A system and method for identifying a document based on a spectral analysis of the text of the document is described. In some examples, the system generates a document identifier for a rendered document based on assigning values to words in the rendered document, such as values associated with the frequency of use of the word by the rendered document, the absolute or relative position of the word in the rendered document, and so on. The system may use the document identifier to generate a group of documents having similar document identifiers, and choose a likely match from the group of documents based on predictive analysis.
