由于消费者的探索自由，全景视频的制片人经常难以将注意力引导到感兴趣区域(ROI)。一些研究人员假设，外围线索吸引反射性/非自愿注意，而中央视觉中的线索吸引并引导自愿注意。这项混合方法的研究评估了在全景视频中使用中心箭头和外围闪烁来引导和聚焦注意力的有效性。25名成年人戴着带有眼球追踪器的头盔显示器，并在两个全景视频中被引导到14个ROI。在跟踪线索的数量、到达和观察ROI所需的时间、与ROI相关的记忆和用户参与度方面没有显著差异。然而，在闪光后的前500毫秒内，参与者的视线朝向ROI的距离明显比箭头闪光后的距离要大得多。然而，大多数用户更喜欢箭头，并认为它比闪烁的箭头更有价值。这些发现表明，传统的注意范式并不完全适用于全景视频，因为外围线索似乎既涉及到非自愿的注意，也涉及到自愿的注意。文中讨论了理论和实践意义以及局限性。
Filmmakers of panoramic videos frequently struggle to guide attention to Regions of Interest (ROIs) due to consumers’ freedom to explore. Some researchers hypothesize that peripheral cues attract reflexive/involuntary attention whereas cues within central vision engage and direct voluntary attention. This mixed-methods study evaluated the effectiveness of using central arrows and peripheral flickers to guide and focus attention in panoramic videos. Twenty-five adults wore a head-mounted display with an eye tracker and were guided to 14 ROIs in two panoramic videos. No significant differences emerged in regard to the number of followed cues, the time taken to reach and observe ROIs, ROI-related memory and user engagement. However, participants’ gaze travelled a significantly greater distance toward ROIs within the first 500 ms after flicker-onsets compared to arrow-onsets. Nevertheless, most users preferred the arrow and perceived it as significantly more rewarding than the flicker. The findings imply that traditional attention paradigms are not entirely applicable to panoramic videos, as peripheral cues appear to engage both involuntary and voluntary attention. Theoretical and practical implications as well as limitations are discussed.
