In recent years 360$^{\circ}$ videos have been becoming more popular. For traditional media presentations, e.g., on a computer screen, a wide range of assessment methods are available. Different constructs, such as perceived quality or the induced emotional state of viewers, can be reliably assessed by subjective scales. Many of the subjective methods have only been validated using stimuli presented on a computer screen. This paper is using 360$^{\circ}$ videos to induce varying emotional states. Videos were presented 1) via a head-mounted display (HMD) and 2) via a traditional computer screen. Furthermore, participants were asked to rate their emotional state 1) in retrospect on the self-assessment manikin scale and 2) continuously on a 2-dimensional arousal-valence plane. In a repeated measures design, all participants (N = 18) used both presentation systems and both rating systems. Results indicate that there is a statistically significant difference in induced presence due to the presentation system. Furthermore, there was no statistically significant difference in ratings gathered with the two presentation systems. Finally, it was found that for arousal measures, a statistically significant difference could be found for the different rating methods, potentially indicating an underestimation of arousal ratings gathered in retrospect for screen presentation. In the future, rating methods such as a 2-dimensional arousal-valence plane could offer the advantage of enabling a reliable measurement of emotional states while being more embedded in the experience itself, enabling a more precise capturing of the emotional states.

通过头戴式显示器和电脑屏幕比较 360$^{\circ}$ 视频诱发的情绪状态

近年来,360$^{\circ}$ 视频变得越来越流行。对于传统媒体演示,例如在计算机屏幕上,可以使用多种评估方法。可以通过主观量表可靠地评估不同的结构,例如感知质量或观众诱发的情绪状态。许多主观方法仅使用计算机屏幕上呈现的刺激进行验证。本文使用 360$^{\circ}$ 视频来诱导不同的情绪状态。视频 1) 通过头戴式显示器 (HMD) 和 2) 通过传统的计算机屏幕呈现。此外,参与者被要求评估他们的情绪状态 1) 回顾自我评估模型量表和 2) 持续在二维唤醒价平面上。在重复测量设计中,所有参与者(N = 18)都使用了演示系统和评分系统。结果表明,由于呈现系统,在诱导存在方面存在统计学上的显着差异。此外,使用两种演示系统收集的评分在统计上没有显着差异。最后,发现对于唤醒措施,可以发现不同评级方法的统计显着差异,这可能表明在回顾屏幕演示时收集的唤醒评级被低估。未来,诸如二维唤醒价平面之类的评级方法可以提供的优势是能够可靠地测量情绪状态,同时更深入地嵌入体验本身,从而能够更精确地捕捉情绪状态。结果表明,由于呈现系统,在诱导存在方面存在统计学上的显着差异。此外,使用两种演示系统收集的评分在统计上没有显着差异。最后,发现对于唤醒措施,可以发现不同评级方法的统计显着差异,这可能表明在回顾屏幕演示时收集的唤醒评级被低估。未来,诸如二维唤醒价平面之类的评级方法可以提供的优势是能够可靠地测量情绪状态,同时更深入地嵌入体验本身,从而能够更精确地捕捉情绪状态。结果表明,由于呈现系统,在诱导存在方面存在统计学上的显着差异。此外,使用两种演示系统收集的评分在统计上没有显着差异。最后,发现对于唤醒措施,可以发现不同评级方法的统计显着差异,这可能表明在回顾屏幕演示时收集的唤醒评级被低估。未来,诸如二维唤醒价平面之类的评级方法可以提供的优势是能够可靠地测量情绪状态,同时更深入地嵌入体验本身,从而能够更精确地捕捉情绪状态。使用两种演示系统收集的评分在统计上没有显着差异。最后,发现对于唤醒措施,可以发现不同评级方法的统计显着差异,这可能表明在回顾屏幕演示时收集的唤醒评级被低估。未来,诸如二维唤醒价平面之类的评级方法可以提供的优势是能够可靠地测量情绪状态,同时更深入地嵌入体验本身,从而能够更精确地捕捉情绪状态。使用两种演示系统收集的评分在统计上没有显着差异。最后,发现对于唤醒措施,可以发现不同评级方法的统计显着差异,这可能表明在回顾屏幕演示时收集的唤醒评级被低估。未来,诸如二维唤醒价平面之类的评级方法可以提供的优势是能够可靠地测量情绪状态,同时更深入地嵌入体验本身,从而能够更精确地捕捉情绪状态。可能表明在回顾屏幕演示时对唤醒评级的低估。未来,诸如二维唤醒价平面之类的评级方法可以提供的优势是能够可靠地测量情绪状态,同时更深入地嵌入体验本身,从而能够更精确地捕捉情绪状态。可能表明在回顾屏幕演示时对唤醒评级的低估。未来,诸如二维唤醒价平面之类的评级方法可以提供的优势是能够可靠地测量情绪状态,同时更深入地嵌入体验本身,从而能够更精确地捕捉情绪状态。
