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.

Claims

1. A method for determining content, comprising:

determining an initial geographic position of a mobile device;

determining an initial direction in which an imaging component of the mobile device is pointed;

determining a change of direction in which the imaging component of the mobile device is pointed in a new direction, wherein the change of direction is determined at least in part by using the imaging component of the mobile device;

determining content that is associated with the new direction and with a content position that is within a predefined range of the initial geographic position; and

providing the determined content to an output component that outputs the content with a content location indicator, indicating a distance from the initial geographic position to the content position, and indicating a content location relative to the new direction.

2. The method of claim 1, wherein determining a change in direction comprises:

capturing a plurality of images with the imaging component of the mobile device;

analyzing each of the plurality of images to determine a substantially same image pattern in each of the plurality of images;

determining a shift between a first image pattern of a first of the plurality of images and a last image pattern of a last of the plurality of images; and

determining the new direction based on the shift.

3. The method of claim 1, wherein determining the initial direction comprises one of the following:

detecting that the imaging component of the mobile device has been pointed in a known direction;

displaying on the mobile device a pattern of a known object at a known geographic location, and detecting that the mobile device has been moved such that the pattern overlays a camera feed from the imaging component of the mobile device;

detecting that the imaging component of the mobile device has been pointed in a direction of detected linear motion of the mobile device;

detecting that the mobile device has been pointed toward the sun and determining the new direction based on the initial geographic position, a current day, and a current time; and

reading a compass.

4. The method of claim 1, wherein determining the content comprises:

transmitting a search request over a network to a remote search system, wherein the search request includes the initial geographic position and the new direction; and

receiving a search result over the network from the remote search system, wherein search result includes the determined content.

5. The method of claim 1, wherein determining the content comprises:

receiving a search parameter through a user input component of the mobile device; and

searching a content database based on the search parameter, the initial geographic position, and the new direction.

6. The method of claim 1, further comprising filtering the content based on at least one of the following:

8. The method of claim 1, wherein providing the determined content to the output component comprises:

detecting further directional motion of the imaging component of the mobile device; and

indicating that the determined content is within a field of view of the imaging component if the imaging component is moved to a direction pointing at the determined content.

9. The method of claim 1, further comprising:

detecting a zoom operation of the imaging component;

determining a zoomed range based on the zoom operation;

determining alternate content associated with an alternate content position that is within the zoomed range relative to the initial geographic position and relative to the new direction.
