METHOD AND APPARATUS FOR INITIATING AN ACTION

An apparatus comprises a first sensor (101) and second sensor (103) arranged to determine a first and second set of properties for entities being devices or persons, the sets being determined in accordance with different sensor modalities. A first processor (105) determines directions between entities and a second processor (107) determines an orientation of an entity. A first detector (109) detects a bi-directional information exchange link between a first person and another entity out of a plurality of possible bi-directional information exchange links between entities in response to the directions and the at least one orientation. An initiator (111) initiates an action in response to the detection of the bi-directional information exchange link. The detection of the bi-directional information exchange link is in response to the first set of properties and the second set of properties.
