System for defining a personality of a device, the device comprising: a memory in which trigger events and an output generation function are stored, an information obtaining unit configured to obtain environment information from the environment of the device, a computing unit configured to compare the obtained environment information with the stored trigger events and, in case that the environment information matches a trigger event of the stored trigger events, to generate output information which generates an output related to the trigger event, based on said output generation function, and the memory is further configured to store personality trait parameters, wherein the personality trait parameters are preselected from a plurality of available personality trait parameters and define a personality of the device, and for each personality trait parameter of the preselected personality trait parameters for the device, the trigger events are stored associated along with the output information, and characterized in that the system comprises a personality trait determination unit configured to perform a trait generation process, in which a character type database is constructed based on a human traits data base by storing character groups in the character type database, each character group having an individual probability distribution over human traits stored in the human traits database including information on a plurality of topics human beings care about, that the system is configured to perform the personality trait generation process during manufacturing of the device and to configure the output generation function to generate the output information on the basis of a particular personality trait parameter, and the preselected personality trait parameters in the memory are accessible by authorized personal only, and the memory comprises a personality memory section which is configured to store the trigger events associated with the personality trait parameters and output information generated in the personality trait generation process, and the personality trait determination unit is further configured to build a human comment database storing human comments as output information correlated with the human traits and to generate a trigger database storing probability distributions correlating the trigger events with the trait output information and an activation probability of a specific trigger event generating a specific output information, that the output information generated in response to the environment information matching the trigger event is generated such that it deviates from previously output information in response to environment information matching the same trigger event. a memory in which trigger
