Abstract
A device may obtain tracking information of a face or a head of a user, determine a position and orientation of the user, and determine a direction of focus of the user based on the tracking information, the position, and the orientation. In addition, the device may retrieve information associated with a location at which the user focused.
Claims20
A method comprising:
- obtaining, by one or more devices of a mobile communication device, tracking information of a face or a head of a user of the mobile communication device;
- determining, by the one or more devices, a geographic location of the mobile communication device;
- determining, by the one or more devices, a position of the user with respect to the geographic location;
- determining, by the one or more devices, an orientation of the user with respect to the geographic location;
- determining, by the one or more devices, a direction of focus of the user, with respect to the geographic location, based on the tracking information, the position, and the orientation;
- and
- obtaining, by the one or more devices, information associated with a location or geographic feature identified in results of a search, using the direction of focus, of geographic information records related to the geographic location.
4 more elements
A mobile communication device comprising:
- a camera for obtaining an image of a face or a head of a user;
- and
- a processor configured to:
- determine a position of the mobile communication device;
- obtain orientation information of the face or the head by comparing the image and a plurality of images that are associated with different angles of the face or the head;
- determine a direction at which the user is looking based on the obtained orientation information and the position of the mobile communication device;
- determine that the user is looking in the direction for a particular amount of time;
- and
- trigger, when the particular amount of time exceeds a threshold, an operation to obtain information associated with a location where the user is looking based on the direction and the position of the mobile communication device.
6 more elements
A device comprising:
- means for obtaining tracking information of a face, a head, or eyes of a user;
- means for determining a location and a direction in which the user is traveling;
- means for determining a particular direction of a line of sight of the user based on the tracking information, the location, and the direction in which the user is traveling;
- means for determining a duration of time that the user's line of sight is trained in the particular direction;
- means for triggering an operation, when the duration of time exceeds a particular threshold, for identifying a geographic location or feature within a threshold distance associated with the line of sight of the user.
