Designing 4D effects corresponding to audiences' emotional responses is important because 4D effects are critical components of 4D movies that provide rich emotional experiences. The recent increasing popularity of 4D content has led to the development of motion effect technology, which involves motions of the chair according to the scene. However, it is difficult to find studies that systematically investigated the influence of motion effects on audiences' emotional responses. This study investigated the emotional responses of a 4D movie audience to motion effects according to their level of empathy. Participants (mean: 25.0 years, standard deviation: 5.0) with varying levels of empathy watched movie clips provided with or without single pitch motion effects. The degree that the motion effect and empathy affected the elicited emotions differed depending on the emotion type. For example, participants with high empathy reported stronger intensity of fear when short and weak motion effects were exhibited than when there was no motion effect. Distinct motion effect design guidelines that can be adopted to enhance audiences’ emotional experiences were proposed. The findings can be referred to when investigating the emotional responses of 4D movie audiences.

设计与观众的情感反应相对应的4D效果非常重要，因为4D效果是4D电影的关键组成部分，可提供丰富的情感体验。最近4D内容的日益普及导致运动效果技术的发展，该技术涉及椅子根据场景的运动。但是，很难找到能够系统地研究运动效果对听众情绪反应影响的研究。这项研究根据4D电影观众的同理心程度调查了他们对动作效果的情感反应。参与者（平均水平：25.0岁，标准差：5.0）具有不同水平的共情观看的电影剪辑，无论是否带有单次俯仰运动效果。运动效果和同理心对诱发的情感的影响程度因情感类型而异。例如，具有同情心的参与者表示，在表现出短暂和微弱的动作效果时，其恐惧感要强于没有动作效果时的恐惧感。提出了可用于增强听众情感体验的独特运动效果设计指南。调查4D电影观众的情感反应时，可以参考这些发现。
