Abstract: Apparatus and methods are disclosed for processing printed material to provide an index of locations within the printed material that can be associated with external actions such as displaying a graphical image, providing an audio or video output, or providing a multimedia output. The associations are stored in a database. Apparatus and methods are also disclosed that allow a user to image the printed material and by indicating a desired location within the printed material can cause one of the associated actions to be executed.

Abstract: An interactive audio puzzle solving, game playing, and learning tutorial system includes a microphone for receiving speech from a user. An electronic subsystem includes an analog-to-digital converter for converting the speech to digital signals, a speech recognition engine responsive to the analog-to-digital converter for translating the digital signals into user input data, a memory for storing the user input data, rules associated with a type of puzzle, game and/or learning tutorial, and initial data associated with a specific puzzle, game and/or learning tutorial, a logic engine for generating a decision output based on the user input data, and/or the rules and/or the initial data, a speech generation engine responsive to the decision output for providing digital speech representing the decision output, and a digital-to-analog converter for converting the digital speech to analog signals.
