Method for controlling an actuator of a device with a computing unit, comprising: - recognition, by a second computing unit, of an object (O1, O2, O3) and ascertainment of properties (E1', E2', E3') of the object (O1, O2, O3) on the basis of sensor signals of at least one sensor unit; - comparison, by the computing unit, of at least one property (P1', P2', P3') of the properties (E1', E2', E3') of the object (O1, O2, O3) ascertained by the second computing unit with a corresponding reference; - control of the actuator, taking into account the properties (E1', E2', E3') of the object (O1, O2, O3) ascertained by the second computing unit if the at least one property (P1', P2', P3') of the properties (E1', E2', E3') ascertained by the second computing unit has a predetermined similarity to the reference; - preparation of a further object which corresponds to the object (O1, O2, O3) in the at least one property (P1, P2, P3, PR); - recognition of the further object and ascertainment of properties of the further object by the second computing unit on the basis of sensor signals of the sensor unit; - comparison, by the computing unit, of a first number (QR') of the properties (ER') of the further object ascertained by the second computing unit with a corresponding number of references, wherein the first number of properties comprises the at least one property (P1, P2, P3) and at least one further property; and - control of the actuator taking into account the properties (E1', E2', E3') of the object (O1, O2, O3) ascertained by the second computing unit if each property (QR') of the first number of properties (ER') ascertained by the second computing unit has a predetermined similarity to a corresponding reference; characterised in that the actuator is controlled by the computing unit for a predetermined period of time taking into account the properties (E1', E2', E3') of the object (O1, O2, O3) ascertained by the second computing unit if each property (QR') of the first number of properties (ER') of the further object ascertained by the second computing unit has a predetermined similarity to the corresponding reference. - recognition, by a second computing unit, of an object (O1, O2, O3) and ascertainment of properties (E1', E2', E3') of the object (O1, O2, O3) on the basis of sensor signals of at least one sensor unit; - comparison, by the computing unit, of at least one property (P1', P2', P3') of the properties (E1', E2', E3') of the object (O1, O2, O3) ascertained by the second computing unit with a corresponding reference; - control of the actuator, taking into account the properties (E1', E2', E3') of the object (O1, O2, O3) ascertained by the second computing unit if the at least one property (P1', P2', P3') of the properties (E1', E2', E3') ascertained by the second computing unit has a predetermined similarity to the reference; - preparation of a further object which corresponds to the object (O1, O2, O3) in the at least one property (P1, P2, P3, PR); - recognition of the further object and ascertainment of properties of the further object by the second computing unit on the basis of sensor signals of the sensor unit; - comparison, by the computing unit, of a first number (QR') of the properties (ER') of the further object ascertained by the second computing unit with a corresponding number of references, wherein the first number of properties comprises the at least one property (P1, P2, P3) and at least one further property; and - control of the actuator taking into account the properties (E1', E2', E3') of the object (O1, O2, O3) ascertained by the second computing unit if each property (QR') of the first number of properties (ER') ascertained by the second computing unit has a predetermined similarity to a corresponding reference;
