1. A method for providing one of a plurality of available information units to a user, wherein the information units each describe an object at a respective location, wherein the method comprises: a) detecting a geographic position of the user; b) iteratively determining such information units from the plurality of available information units that describe objects situated at locations which have a spatial relationship to the geographic position of the user which meets a geographic selection criterion, selecting an information unit to be reproduced to the user from the determined information units, and reproducing the selected information unit to the user; c) depending on a temporal behavior of the geographic position, a speed and/or a direction of movement of the user, adjusting the geographic selection criterion so that a subsequent selection process is performed with a different geographic selection criterion, wherein the method further comprises: d) prior to step c), detecting the position, speed and/or direction of movement of the user over a time window of predetermined duration to detect the temporal behavior, wherein step b) includes selecting those information units that describe objects at locations situated so that a distance of the geographic position of the user from the location of the object or an angle between the direction of movement of the user and a line running through the geographic position of the user and the location of the object is below or exceeds a selection parameter, wherein step b) further comprises the following substeps: b1) evaluation of the detected temporal behavior in the time window of a predetermined time period to obtain a statistical characteristic or measure; and b2) adjusting the geographic selection criterion depending on the statistical characteristic, and wherein in step d) the temporal behavior is also determined over a further time window of a further predetermined time period which is longer than the time period of the predetermined time window, and wherein step b) further comprises the following substeps: prior to step b2), evaluation of the detected temporal behavior in the further time window to obtain a further statistical characteristic which is a further measure for changes in the temporal behavior, concluding a situation of the user from a plurality of predetermined situations based on the further statistical characteristic, wherein one or more values defining a functional connection between the selection parameter and the statistical characteristic are associated with each situation; wherein the adjustment of step b2) comprises adjusting the selection parameter depending on the statistical characteristic on the basis of the functional connection defined by the value and/or values associated with the situation.
