由于计算机图形学、可穿戴技术和连接技术的最新进展,虚拟现实(VR)已经进入了我们的日常生活。VR中一个关键的新奇是用户的角色,它已经从被动变成了完全主动。因此,改进编码-交付-渲染链的任何方面都需要从理解用户行为开始。为此,我们研究了用户在6自由度(DoF)VR环境中的导航轨迹。具体来说,我们调查的主要区别和相似之处3和6自由度导航通过现有的方法,通过研究用户行为在3自由度设置。我们的仿真结果,基于真实的导航路径的用户,同时显示动态体媒体在6自由度的条件下,显示3自由度的聚类算法在6自由度用户相似性评估的局限性。鉴于这些观察结果,我们需要开发新的解决方案,用于分析6自由度轨迹。
Thanks to recent advances in computer graphics, wearable technology, and connectivity, Virtual Reality (VR) has landed in our daily life. A key novelty in VR is the role of the user, which has turned from merely passive to entirely active. Thus, improving any aspect of the coding-delivery-rendering chain starts with the need for understanding user behaviour. To do so, we investigate the navigation trajectories of users within a 6-Degrees-of-Freedom (DoF) VR environment. Specifically, we investigate the main differences and similarities between 3 and 6-DoF navigation through existing methodologies adopted to study user behaviour in 3-DoF settings. Our simulation results, based on real navigation paths of users while displaying dynamic volumetric media in 6-DoF conditions, show the limitations of clustering algorithms for 3-DoF in assessing user similarity in 6-DoF. Given these observations, we state the need for developing new solutions for the analysis of 6-DoF trajectories.
