我们评估了注视方向和其他非语言视觉线索对多方中介沟通的影响。三组参与者（两个演员，一个主题）解决了三个视听通信条件下的语言难题。每种条件都向受试者呈现不同的演员图像选择：（1）14%凝视的正面运动视频;（2）头部方向和7%凝视的运动视频;（3）头部方向和32%凝视的静止图像。头部方向线索的存在导致受试者使用两倍多的指示参考的人。我们发现受试者感知到的演员凝视量和受试者说话的次数之间存在线性关系。缺乏凝视会使多方中介系统的话轮转换效率降低25%。这是因为凝视传达了一个人是否被称呼或被期望说话，并用于调节社交亲密度。建议在多方调解系统中支持注视方向提示。
We evaluated effects of gaze directional and other non-verbal visual cues on multiparty mediated communication. Groups of three participants (two actors, one subject) solved language puzzles in three audiovisual communication conditions. Each condition presented a different selection of images of the actors to subjects: (1) frontal motion video with 14% gaze; (2) motion video with head orientation and 7% gaze; (3) still images with head orientation and 32% gaze. Presence of head orientation cues caused subjects to use twice as many deictic references to persons. We found a linear relationship between the amount of actor gaze perceived by subjects and the number of speaking turns taken by subjects. Lack of gaze can decrease turn-taking efficiency of multiparty mediated systems by 25%. This is because gaze conveys whether one is being addressed or expected to speak, and is used to regulate social intimacy. Support for gaze directional cues in multiparty mediated systems is recommended.
