Abstract
Embodiments of the invention are directed to obtaining information based on directional orientation of a mobile imaging device, such as a camera phone. Visual information is gathered by the camera and used to determine a directional orientation of the camera, to search for content based on the direction, to manipulate 3D virtual images of a surrounding area, and to otherwise use the directional information. Direction and motion can be determined by analyzing a sequence of images. Distance from a current location, inputted search parameters, and other criteria can be used to expand or filter content that is tagged with such criteria. Search results with distance indicators can be overlaid on a map or a camera feed. Various content can be displayed for a current direction, or desired content, such as a business location, can be displayed only when the camera is oriented toward the desired content.
