A New Humanoid Architecture for SocialInteraction between Human and a RobotExpressing Human-Like Emotions Usingan Android Mobile Device as Interface

In this paper we illustrate a humanoid robot able to interactsocially and naturally with a human by expressing human-like bodyemotions. The emotional architecture of this robot is based on an emotionalconceptual space generated using the paradigm of Latent SemanticAnalysis. The robot generates its overall affective behavior (Latent SemanticBehavior) taking into account the visual and phrasal stimuli ofhuman user, the environment and its personality, all encoded in his emotionalconceptual space. The robot determines its emotion according byall these parameters that influence and orient the generation of his behaviornot predictable from the user. The goal of this approach is toobtain an affinity matching with humans. The robot exhibit a smoothlynatural transition in his emotion changes during the interaction withhumans taking also into account the previous generated emotions. Tovalidate the system, we implemented the distribute system on an AldebaranNAO small humanoid robot and on a Android Phone HTC andwe tested this social emotional interaction using the phone device asintelligent interface between human and robot in a complex scenario.
