在自动情感表情分析中，头部运动被认为是一个讨厌的变量，在提取动作单元或表情检测的特征时需要控制。作为理解头部运动对情感交流的贡献的第一步，我们调查了有人际暴力史的亲密夫妇中刚性头部运动的人际协调。冲突和非冲突的情节引起的二元互动任务，并验证使用语言标准。头部运动参数进行了分析，使用学生的配对t检验;演员合作伙伴分析，以模拟夫妇之间的相互影响;和窗口交叉相关，以揭示动态的变化方向的影响随着时间的推移。合作伙伴的偏航RMS角位移和俯仰和偏航的RMS角速度均表明合作伙伴之间存在强烈的相互影响。在冲突期间，合作伙伴的俯仰RMS角位移较高。在冲突和非冲突，头部角位移和角速度的俯仰和偏航的强烈相关性，与频繁的变化，领先滞后的关系。合作伙伴的头部运动之间的整体协调量更高度相关的非冲突相比，冲突的互动。当冲突增加头部运动时，它会削弱人际协调。
In automatic emotional expression analysis, head motion has been considered mostly a nuisance variable, something to control when extracting features for action unit or expression detection. As an initial step toward understanding the contribution of head motion to emotion communication, we investigated the interpersonal coordination of rigid head motion in intimate couples with a history of interpersonal violence. Episodes of conflict and non-conflict were elicited in dyadic interaction tasks and validated using linguistic criteria. Head motion parameters were analyzed using Student’s paired t-tests; actor-partner analyses to model mutual influence within couples; and windowed cross-correlation to reveal dynamics of change in direction of influence over time. Partners’ RMS angular displacement for yaw and RMS angular velocity for pitch and yaw each demonstrated strong mutual influence between partners. Partners’ RMS angular displacement for pitch was higher during conflict. In both conflict and non-conflict, head angular displacement and angular velocity for pitch and yaw were strongly correlated, with frequent shifts in lead-lag relationships. The overall amount of coordination between partners’ head movement was more highly correlated during non-conflict compared with conflict interaction. While conflict increased head motion, it served to attenuate interpersonal coordination.
