  • Publication number: 20130238234
    Abstract: Apparatuses, methods, systems and computer-readable media for using visibility maps of identified points of interest (POIs) to determine a user's location are presented. Users may determine their locations without relying on a global positioning technique, such as GPS or A-GPS. A user may instead rely on POIs identifiable from the user's visual field of view, and determine position based on the common area visible to each identified POI.

  • Publication number: 20130230208
    Abstract: A mobile device can receive OCR library information associated with a coarse position. The coarse position can be determined by the mobile device, or by a network server configured to communicate with the mobile device. A camera on the mobile device can obtain images of human-readable information in an area near the coarse position. The view finder image can be processed with an OCR engine that is utilizing the OCR library information to determine one or more location string values. A location database can be searched based on the location string values. The position of the mobile device can be estimated and displayed. The position estimated can be adjusted based on the proximity of the mobile device to other features in the image.
