People with communication difficulties encounter several challenges in their daily online interactions, such as a limited right to talk (RoT), insufficient social support (SS), and a low sense of being attended to (SoBA). Computer-mediated technologies are limited in addressing such problems owing to their limited capacity in transferring verbal and nonverbal cues between users. In this study, to address the limited RoT, low SS, and low SoBA challenges, we proposed a robotic video conference system with two teleoperated robot avatars. The proposed system was compared with another robotic video conference system that adopts only one teleoperated robot avatar. In the field experiment, 37 participants took part in two discussion sessions using each system type, where RoT, SS, and SoBA were adopted as the measured indices. The proposed system significantly increased the users’ RoT and SS compared with other robotic video conference systems. This study contributes to the literature by demonstrating the effect exerted by the type of robotic video conference adopted on users’ feelings about RoT, SS, and SoBA.
