Feedback interface for visible congruent facial expression: Towards better face-to-face communication

Facial expressions are important in face-to-face communication between two individuals as expressions vary dynamically and provide impressions to observers. If facial expressions are congruent on both sides, consciously or unconsciously, a trust relationship is created and the individuals have positive impressions of each other. In this paper, psychological evaluation without direct interaction between individuals is practiced. The aim is to analyze the different dynamic characteristics that smiles have on impressions for an interface for feedback of visible congruent facial expression. The interface concept is described.
