The emergence of high-performance mobile devices and communication networks has provided people with new ways of producing video content. In the past, people recorded videos using professional devices such as camcorders, but now they use their smartphones, wearable video recorders and drones. Because of this change, there is strong interest among users in Internet of Things environments in the context of how video is captured, edited, shared and interacted with. In particular, trends show a shift from professional-edited video content to user-generated video content, with the increasing popularity of video-sharing social media and the emergence of new video recording devices. However, there have been very few studies that have explored how a snapshot video can be edited. Only a few researchers have studied the effects of video on social interaction among users, and they have failed to consider how video content creation can facilitate social interaction. Therefore, we conducted experimental research to discover the impact of scene format (narrative focus and perspective) of everyday videos on narrative engagement and social interaction. We conducted two studies: (i) single condition effect of narrative focus and narrative perspective, and (ii) mixed condition effect of narrative focus and narrative perspective. The results indicated that the single narrative focus and narrative perspective affects narrative engagement and its four sub-constructs. In addition, the mixed narrative focus and narrative perspective affected narrative engagement, and the effects of interaction between them were determined. According to narrative engagement patterns, the tendencies of social interactions, including various system features, were different. The implications and limitations of the study’s results are discussed in the final section of the article. [ABSTRACT FROM AUTHOR]

We have entered the era of personal video sharing. Social media and wearable devices now offer new video interfaces, allowing users to record videos of their everyday experiences quite easily. Videosharing users are mostly interested in creating narratives and promote active social interaction with others. A critical design feature for creating narratives that facilitate social interaction is the temporal format of the everyday experience video. Although the importance of video narratives as a way of representing the human experience has been emphasized, relatively little research has been carried out on the temporal format of video such as the duration of video and the number of scenes (NS) in the video. Therefore, we conducted a pre-study with qualitative research and a main study with experimental research to discover the impact of temporal format of everyday video on narrative engagement (NE) and social interactivity (SI). In the pre-study, we observed users' perceptions of shared videos on social media. In particular, we examined how people feel and become engaged based on the temporal format of narratives. In the main study, we examined the effect of temporal format on the NE and the effect of NE on social interaction. The results indicated that the NE fully mediates the effect of temporal format of video on SI. In other words, the duration of video and the NS in everyday videos do not affect the SI directly, only through the NE. The NS becomes more important, however, when the length of the video gets longer. The NE was not increased in correlation with the NS unless there is long enough overall time for the entire video. Implications and limitations of the study results are discussed in the final section of the paper. [ABSTRACT FROM AUTHOR]
