Process of controlling at least one actuator integrated in a building automation system depending on the position of a person, in which process the results of at least two different locating methods are used for the person-related position determination, and which process comprises the following steps: - Weighting the locating results of each locating method according to its person-related hit probability and position detection accuracy, - Determining the current position of the person based on the weighted results of the locating methods, - Comparing the determined position (P e) with positions (P a) defined as actuator-triggering and stored in a database, - if the determined position (P e) corresponds sufficiently to a position (P a) defined as actuator-triggering, activation of the at least one actuator assigned to the position with the control data provided for this position via the building automation system and - carrying out a situation evaluation with regard to the hit probability and the detection accuracy of the determined position (P e) of the person, wherein the current results of the locating methods, reference data records of these locating methods which are stored in a database and correspond to the determined position (P e) and, if any, a correction control carried out by the person as a reaction to the actuator activation are included in the situation evaluation, and wherein the weighting factor of at least one of the locating methods is adapted to correct the determined position (P e) if the situation evaluation is negative, wherein a negative situation evaluation is caused by the system or by a correction control, and wherein a person-side correction control of an actuator other than that controlled by the building automation system leads to a negative situation evaluation, and then the weighting factor or factors of the locating methods, whose results have been used to determine the position, are adapted so as to adapt the determined position (P e) of the person to that corresponding to the predefined actuator-triggering position (P a) corresponding to the actuator activated by the person in the course of the correction control. - Weighting the locating results of each locating method according to its person-related hit probability and position detection accuracy, - Determining the current position of the person based on the weighted results of the locating methods, - Comparing the determined position (P e) with positions (P a) defined as actuator-triggering and stored in a database, - if the determined position (P e) corresponds sufficiently to a position (P a) defined as actuator-triggering, activation of the at least one actuator assigned to the position with the control data provided for this position via the building automation system and - carrying out a situation evaluation with regard to the hit probability and the detection accuracy of the determined position (P e) of the person, wherein the current results of the locating methods, reference data records of these locating methods which are stored in a database and correspond to the determined position (P e) and, if any, a correction control carried out by the person as a reaction to the actuator activation are included in the situation evaluation, and wherein the weighting factor of at least one of the locating methods is adapted to correct the determined position (P e) if the situation evaluation is negative, wherein a negative situation evaluation is caused by the system or by a correction control, and wherein a person-side correction control of an actuator other than that controlled by the building automation system leads to a negative situation evaluation, and then the weighting factor or factors of the locating methods, whose results have been used to determine the position, are adapted so as to adapt the determined position (P e) of the person to that corresponding to the predefined actuator-triggering position (P a) corresponding to the actuator activated by the person in the course of the correction control.
