1. A method, comprising:
- activating, by a device, a transponder in at least one position marker;
receiving wireless signals transmitted from position markers into the device;
receiving schematic information via wireless communication into the device;
displaying a list of position markers from which the wireless signals were received on the device;
determining, by the device, a current position of the device based on the wireless signals;
selecting, on the device, a position marker from the list of position markers; and
displaying, on the device, the current position of the device with respect to the schematic information and the relative direction towards the selected position marker.

Abstract
A system for indicating the relative direction of a target object or location as determined from the current position of a wireless communication device. The system employs Direction of Arrival determination using an antenna array for indicating the direction of a target device and includes facilities to activate a location-indicating transmission in a target device, the ability to request that a location-indicating transmission be activated in a remote target device, relevant information reception from a target device and the display of all potential target devices within effective transmission range of the wireless communication device.
