Background: In the European Union (EU) research project "HOBBIT" prototypes of assistive robots were developed in order to support a more secure and independent life style and trials were run at the homes of elderly users.; Objective: The project "personAAL" aimed at investigating whether distinct behavioral forms of a robot ("personality"), despite an identical basic function (e.g. bringing a message) are perceived as different personalities by the test persons.; Material and Methods: For this study a robot was equipped with two types of behavior, one more introverted (purely function-oriented, impersonal and factual) and the other more extroverted (lively and enriched). The two types of behavior were demonstrated to 13 test persons (mostly older persons and experts from the care domain).; Results: Nearly all of the test persons (12 out of 13) perceived a difference with respect to the behavior of the robot. Of the test persons 1 preferred the introverted robot, 9 the extroverted behavior of the robot and 3 had no preferences or stated that the preference depended on the context. The evaluation of answers to the Godspeed questionnaire resulted in significantly different perceptions of "anthropomorphism" and "animated" as well as in the total evaluation. It is also remarkable that no significant differences could be found for "likeability" and "perceived security". There was also no significant correlation between the preferred behavior of the robot and the self-assessment of the test person as being more introverted or extroverted.; Conclusion: From these results it can be concluded that acceptance of a robot does not solely depend on the mere function, which of course is a precondition but that it is advisable to offer a choice between different types of behavior in order to optimize acceptance.
