Affective human-robot interaction might become an important part of our future lives. Within this context the so-called ‘uncanny valley effect’ in robotics describes a function of the anthropomorphism of robots and the perceived uncanniness. However, there is little psychological research. Besides, most studies use highly artificial or restricted settings. This experimental study investigates how different types of robots and their expressions of emotional states are perceived in complex affective settings in order to examine robots’ design aspects for an authentic affective human-robot interaction.
