A communication device can be equipped with global positioning system (GPS) equipment and one or more accelerometers and/or gyroscopes that can be used to determine one or more of the direction or velocity at which the communication device is“cast”by coupling the location information of the communication device, such as using GPS coordinates, cell tower triangulation, or the like, with the“cast direction”of the communication device—thereby creating a cast vector. The strength of the cast may be analyzed to assist with determining how far the cast vector should be projected. The communication device can then determine which, if any, other communications device, entities, and/or objects are within the cast vector. The direction and strength of the cast can be used to assist in creating either a two or three-dimensional sensible area, that originates with the location of the calling party, and extends therefrom a certain distance.
