One of the most recent trends in the evaluation of immersive virtual environments is the incorporation of user metrics. In this article, we conduct a user study on a 360° hypervideo, using a dashboard based on detailed metrics obtained from users’ interactions with 360° hypervideos. It is essential to evaluate the quality of experience to monitor service quality from the perspectives of consumers. We demonstrate a framework to examine the user experiences of 360° environments and evaluate them using the xAPI specification, facilitating the development of analytics solutions centered in the user experience; and how the graphs and related data composing the dashboard provide valuable information about ways of navigating and interacting with 360° video experiences, as well as the time invested in them. In the user study, we include the visual perception, attention, tracking and interaction of users watching Proemaid (a 360° multimedia production), collected from an interactive 360° video player in the form of xAPI statements. The Proemaid production has been played in a vast variety of contexts by stakeholders from government, technology and education, among others. Therefore, the quantitative results and the qualitative analysis of the user study are intended to outline a sketch of the users’ ways of navigating, interacting and investing time in 360° hypervideo productions. We consider that these metrics will be very interesting in the specification of new omnidirectional storyboards for film producers of content in 360°. Finally, we propose potential directions for empirical investigation that highlight its great potential in many fields.

成功360°超视频设计的关键:基于xAPI分析仪表板的用户研究

沉浸式虚拟环境评估的最新趋势之一是用户指标的整合。在本文中,我们基于从用户与360°超级视频互动中获得的详细指标,使用仪表板对360°超级视频进行了用户研究。评估体验质量以从消费者的角度监视服务质量至关重要。我们演示了一个框架,用于检查360°环境的用户体验并使用xAPI规范对其进行评估,从而促进了以用户体验为中心的分析解决方案的开发;以及构成仪表板的图形和相关数据如何提供有关导航和与360°视频体验进行交互的方式以及在其中花费的时间的宝贵信息。在用户研究中,我们包括观看Proemaid(360°多媒体产品)的用户的视觉感知,注意力,跟踪和互动,这些内容以xAPI语句的形式从交互式360°视频播放器中收集。政府,技术和教育等方面的利益相关者在各种各样的背景下进行了Proemaid的制作。因此,用户研究的定量结果和定性分析旨在概述用户在360°超视频产品中导航,交互和投入时间的方式。我们认为这些指标对于360°内容电影制片人的新全向情节提要的规范将非常有趣。最后,我们提出了实证研究的潜在方向,以突出其在许多领域的巨大潜力。跟踪观看Proemaid(360°多媒体产品)的用户的互动和互动,该视频以xAPI语句的形式从交互式360°视频播放器中收集。政府,技术和教育等方面的利益相关者在各种各样的背景下进行了Proemaid的制作。因此,用户研究的定量结果和定性分析旨在概述用户在360°超视频产品中导航,交互和投入时间的方式。我们认为这些指标对于360°内容电影制片人的新全向情节提要的规范将非常有趣。最后,我们提出了实证研究的潜在方向,以突出其在许多领域的巨大潜力。跟踪观看Proemaid(360°多媒体产品)的用户的互动和互动,该视频以xAPI语句的形式从交互式360°视频播放器中收集。政府,技术和教育等方面的利益相关者在各种各样的背景下进行了Proemaid的制作。因此,用户研究的定量结果和定性分析旨在概述用户在360°超视频产品中导航,交互和投入时间的方式。我们认为这些指标对于360°内容电影制片人的全新全向情节提要的规范将非常有趣。最后,我们提出了实证研究的潜在方向,以突出其在许多领域的巨大潜力。
