Environment based on emotion recognition for human-robot interaction

In computer sciences, the development of interactive environments have motivated the study of emotions, especially on the context of mobile devices. Research in human-robot interaction have explored emotions to create natural experiences on interaction with social robots. A fertile aspect consist on practical approaches concerning changes on the personality of an artificial system caused by modifications on the users inferred emotional state. The present project proposes to develop, for Android platform, an environment for human-robot interaction based on emotions. A dedicated module will be responsible for recognizing emotions by analyzing facial expressions. This system consisted of a virtual agent aggregated to an application, which used information of the emotion recognizer to adapt its interaction strategy, alternating between two pre-defined discrete paradigms. In the experiments performed, it was found that the proposed approach tends to produce more empathy than a control condition, however this result was observed only in sufficiently long interactions.
