Mobile endpoints are provided that enable direction based pointing services including 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 and a location based engine that processes the positional information and the direction information to determine a subset of points of interest relative to the portable electronic device as a function of at least the positional information and the direction information. Devices can include compass(es), e.g., magnetic or gyroscopic, to determine a direction and GPS systems for determining location. A component for determining acceleration can also optionally be included.
