A method and system for generating output from an electronic reading device is based on a detected position of the electronic reading device relative to a predefined address pattern on a specially formatted paper. Based on a periodic detection of successive positions of the electronic reading device, a printer on the electronic reading device is activated in a manner such that stored text or graphics are printed on the specially formatted paper. The printing can be accomplished, for example, using a thermo-print head of the electronic reading device in connection with a thermal sensitive paper. Either as an alternative to or in addition to printing, the electronic reading device can also generate an audio output based on the detected location of the electronic reading device.

Printer pen

A method and system for retrieving position-related information uses a map of a selected geographical area printed on a surface that includes an address pattern. Each position on the address pattern corresponds to a particular location within the selected geographical area. By detecting a portion of the address pattern with an electronic reading device, a precise position of the electronic reading device with respect to the address pattern can be determined. A server identifies the specific geographical location that corresponds to the precise position. The specific geographical location can then be stored or information relating to the specific geographical location can be retrieved and forwarded to the user of the electronic reading device. Preferably, the map is printed on a region of address pattern that is predefined as corresponding to the selected geographical area.

Positioning applications for an electronic reading device

A method and system for monitoring moving parts relies upon a formatted surface of a moving part. The formatted surface includes an address pattern wherein a precise position relative to the address pattern can be determined from a portion of the address pattern. An electronic reading sensor detects a portion of the address pattern, and a processor uses the detected portion of the address pattern to determine a current position of the moving part.
