ABSTRACT:

The task of this Master's thesis was to explore the influence of adaptations towards the user perception of a spoken dialogue system. The focus is on the social acceptance and the social actorship of the system. Further investigated dimensions are user experience, engagement and external control. The investigation was carried out using a spoken dialogue system in form of an embodied agent named VirtualK. VirtualK is an information system which informs the user about ongoing and past projects of the Telekom Innovation Laboratories. There are two versions of VirtualK available: an adaptive and a non-adaptive one.
To investigate and evaluate the influence of adaptations on the user perception a questionnaire was developed which illustrates all above mentioned dimensions, except engagement. The engagement of the test subjects was determined by the log data. The results of the questionnaire and the log data have been complemented by an interview with the test subjects about the differences of both versions.
