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.
Claims50
A method in a computing system, comprising:
- receiving, by a processor of the computing system, a sequence of one or more words optically or acoustically captured from a rendered document by a user;
- identifying, by a processor of the computing system, among the words of the sequence a word with which an action has been associated;
- and
- performing the associated action by a processor of the computing system.
A system for responding to the capturing of text from a rendered document, comprising:
- a handheld optical and/or acoustical capture device usable by a user to capture a sequence of one or more words from a rendered document;
- and
- a processor that identifies among the words of the sequence captured with the handheld optical and/or acoustical capture device a word with which an action has been associated, and that performs the associated action.
A computer-readable medium containing a data structure mapping keywords to actions, the data structure comprising:
- for each of a plurality of keywords that may be captured from rendered documents using a handheld optical and/or acoustical capture device, an entry containing information specifying an action to be performed with respect to a user who captures the keyword from a rendered document using a handheld optical and/or acoustical capture device.
A method in a computing system, comprising:
- receiving, by a processor of the computing system, a sequence of human readable characters optically captured from a rendered document by a user;
- identifying, by a processor of the computing system, among the sequence a subset of the sequence with which an action has been associated;
- and
- performing the associated action by a processor of the computing system.
A method in a computing system of selecting an action to be performed in response to an optical capture of a sequence of characters from a rendered document, the method comprising:
- identifying, by a processor of the computing system, two or more actions to be performed that are associated with a markup element that includes at least one distinguised character within the sequence of characters;
- determining, by a processor of the computing system for each identified action, a number of characters shared by the markup element and the sequence of characters;
- and
- selecting, by a processor of the computing system, an action to be performed based on a comparison of the determined number of characters for each identified action.
A method in a computing system, comprising:
- receiving, by a processor of the computing system, a sequence of one or more words optically or acoustically captured from a rendered document by a user;
- identifying, by a processor of the computing system, an action to be performed associated with a location in the rendered document proximate to the received sequence;
- and
- performing the identified action by a processor of the computing system.
