  We propose See-Through Face Display, a display that facilitates mutual gaze
communication with remote users through the display. This display comprises a
transparent display that repeatedly turns on and off and a camera installed
behind the display so that the user's gaze and the optical path of the camera
are closely aligned. This display is designed to show the user's face, and eye
contact occurs when the user looks at the face on the display. Therefore, by
using this display for all participants in a conversation, users can
communicate with each other via the face on the display via facial and gaze
cues. This interaction provides an experience as if the remote user's face were
present in the local environment. See-Through Face Display proposes the
importance of mutual gaze communication in telepresence.
