<p>The method involves defining a reference area (RA1), and arranging electric field and/or magnetic field probes (P1, P2) proximate to or inside the reference area. A portable emitter device is arranged within the area. Detection signals (S1, S2) of the electric field and/or magnetic field emitted by the emitter device are received from the probes. The received detection signals are analyzed to determine the location of the emitter device within the reference area. Independent claims are also included for the following: (1) a method for performing an interactive action (2) a man/machine interface system for use with a portable emitter device such as a mobile telephone emitting an electric field or a near field communication (NFC) device emitting a magnetic field.</p> |
