Perception of congruent facial and haptic expressions of emotions

Haptic expression of emotions has received less attention than other modalities. Bonnet et al. [2011] combine visio-haptic modalities to improve the recognition and discrimination of some emotions. However, few works investigated how these modalities complement each other. For instance, Bickmore et al. [2010] highlight some non-significant tendencies of complementarity between the visual and haptic modalities.
