Searching by use of machine-readable code content
First Claim
Patent Images
1. A method of navigation and input comprising:
- imaging a mark whereby an image of that mark is captured by an imager sensor,determining at least part of the location of that image of the mark in the imager sensor,determining the number of image pixels in which that image of the mark is captured by the imager sensor,establishing a threshold of change in the number of image pixels in which that image of the mark is captured by the imager sensor,establishing a time frame threshold over which such change occurs,establishing whether the exceeding or the failure to exceed those thresholds is intended to indicate an action to be taken within the computerized application,tracking the number of image pixels in which that image of the mark is captured by the imager sensor,generating a signal to the application that an action should be taken based on the tracked number of image pixels in which the image of the mark is captured by the imager sensor exceeding or failing to exceed the thresholds established, andperforming the action so signaled.

Abstract
A method of searching the Internet or onboard database or other source through devices that contain or are coupled to cameras or other imaging devices, the method including extracting search terms from the human-understandable content encoded in a machine-readable code and displayed to the recipient on the device following the imaging of that code by the device'"'"'s imager. The method of search utilizes a method of navigation and input that produces a location indicator on the device display that corresponds to the location of an image of a machine-readable code in the sensor of the device'"'"'s imager.
