1. A portable electronic device, comprising: a positional component for receiving positional information as a function of a location of the portable electronic device; a directional component that outputs direction information as a function of an orientation of the portable electronic device; a location based engine that processes the positional information and the direction information to dynamically determine a subset of points of interest that are within the portable electronic device's line of sight along a vector path determined by at least the positional information and the direction information, the line of sight along the vector path comprising an arc and distance that define a line of sight area, such that points of interest determined to be in the line of sight area are included in the subset of points of interest; and an interface configured to display the determined subset of points of interest.
