Query: Evaluation of a RGB-LED-based Emotion Display for Affective Agents   Technology has become an essential part in every aspect of our lives. However
the key to a successful implementation of a technology depends on the
acceptance by the general public. In order to increase the acceptance various
approaches can be applied. In this paper, we will examine the human-robot
emotional interaction by investigating the capabilities of a developed
low-resolution RGB-LED display in the context of artificial emotions. We are
focusing on four of the most representative human emotions which include
happiness, anger, sadness and fear. We will work with colors and dynamic light
patterns which are supposed to evoke various associations. In an experiment,
the use these patterns as expressions of emotions are validated. The results of
the conducted study show that some of the considered basic emotions can be
recognized by human observers.
