Abstract (in Japanese) (See Japanese page) 
(in English) We previously constructed a light field (LF) facial communication system by introducing point-cloud representation to a near virtual-image mode LF display, which aims to transmit facial expressions. In this study, we conducted an experiment to evaluate the facial communication system by measuring the user’s facial electromyography (EMG) activity. The EMG responses were compared when subjects observed a smile and a frown presented using the LF and two-dimensional (2D) displays. The results showed that the frown expression presented with the LF display significantly elicited higher EMG responses than the one presented with the 2D display.
