Viewpoint Control in Interactive Virtual Reality Film Experiences

虚拟现实(VR)电影正在成为这一新兴技术的热门应用。VR电影设计中的一个主要问题是视点控制；与呈现给观众的镜头最终由导演选择的传统电影不同，VR引入了用户可以交互控制他们的视点(包括位置和旋转)的可能性。因此，VR内容的观众可能会将目光从电影创作者想要的场景中移开。这给这种新媒体的讲故事设置了障碍。一种可能的解决方案是禁用视点控制，但可能会失去沉浸感。本课题研究VR电影视点控制中的两个相互关联的问题。我们首先建议评估交互式视点控制与非交互式视点控制在用户体验和沉浸感方面的优点。其次，我们将经验性地比较控制视角方向的机制，为VR电影制作人提供工具，帮助他们更好地理解和使用电影中的互动性。

Virtual reality (VR) film is becoming a popular application of this emerging technology. A major problem in VR film design is that of viewpoint control; unlike traditional film where the shots presented to the viewer are ultimately chosen by the director, VR introduces the possibility that users may interactively control their viewpoint (both in terms of position as well as rotation). Consequently, viewers of VR content may look away from scenes intended by the film creators. This imposes barriers in storytelling in this new medium. A potential solution is to disable viewpoint control, at the possible loss of immersion. This project investigates two interrelated problems in VR film viewpoint control. We first propose to evaluate the merit - in terms of impact on user experience and immersion - of interactive vs. non-interactive viewpoint control. Second, we will empirically compare mechanisms to control the view direction, giving VR film makers tools to help them better understand and employ interactivity in their films.
