Abstract：
Virtual Reality is an effective technique for eliciting emotions. It provides immersive and ecologically valid emotional experiences while maintaining experimental control. Recently, novel VR forms like 360° videos have been used successfully for emotion elicitation. Some preliminary databases of 360° videos for emotion elicitation have been proposed, but they tapped mainly into an emotional dimensional approach and did not include a concurrent physiological assessment of an emotional profile. This study expands on these databases by combining dimensional and discrete approaches to validate a new set of 360° emotion-inducing images. Twenty-six participants viewed 46 immersive images, and their emotional reactions were measured using self-reporting, psychophysiological signals, and eye tracking. The IAVRS database can successfully elicit a wide range of emotional responses, including both positive and negative valence, as well as different levels of arousal. Results reveal an important correspondence between the discrete and dimensional models of emotions. Furthermore, the images that exhibit convergence between the dimensional and discrete emotional models are particularly impactful regarding arousal and valence values. The IAVRS database provides insights into potential relationships between physiological parameters and emotional responses. This preliminary investigation highlights the complexity of emotional elicitation processes and their physiological correlates, suggesting the need for further research to deepen our understanding.
摘要：
虚拟现实是一种有效的激发情感的技术。它提供身临其境和生态有效的情感体验，同时保持实验控制。最近,诸如360°视频之类的新型VR形式已成功用于情感激发。已经提出了一些用于情感激发的360°视频的初步数据库，但是他们主要采用了情感维度的方法，并且没有同时对情感状况进行生理评估。这项研究通过结合维度和离散方法来扩展这些数据库，以验证一组新的360°情感诱导图像。26名参与者观看了46张身临其境的图像，他们的情绪反应是用自我报告来衡量的，心理生理信号，和眼动追踪。IAVRS数据库可以成功地引发广泛的情绪反应，包括正价和负价，以及不同程度的唤醒。结果揭示了情感的离散模型和维度模型之间的重要对应关系。此外，在维度和离散情绪模型之间表现出趋同的图像在唤醒和效价值方面特别有影响力。IAVRS数据库提供了对生理参数和情绪反应之间的潜在关系的见解。这项初步调查强调了情感激发过程及其生理相关性的复杂性，这表明需要进一步研究以加深我们的理解。
