Abstract:
A method comprising the steps of:determining a location of a device at a time of an input from a user; determining a bearing from the device at the time; determining a search area, the search area bounded by a clockwise bearing vector, a counterclockwise bearing vector and a radius, the clockwise bearing vector and counterclockwise bearing vector offset from the bearing; determining a set of objects that lie within the search area; determining if a desired object is contained within the set of objects; in response to a determination that the desired object is not contained within the determined set of objects, increasing the search area by changing at least one of the clockwise bearing vector and the counter clockwise vector; and retrieving information relating to a set of objects that correspond to the determined location and bearing of the device.
