Development and Evaluation of a Mask-type Display Transforming the Wearer's Impression

The facial expression that arises from our emotion takes an important role in face-to-face communication. Some might not be good at making an appropriate facial expression according to the situation. In this paper, we propose a mask-type display that can transform the wearer's visual impression. The display shows a computer-generated mouth. This virtual mouth is always synchronized with the shape of the wearer's actual mouth in real-time. The wearer can reflect four emotions on the virtual mouth no matter what shape of the mouth the wearer makes. The experimental results suggested that the virtual mouth with joy or anger had some effect on the wearer's impression in face-to-face communication.
