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问题；与传统电影中呈现给观众的镜头最终由导演选择不同，VR引入了一种可能性，即用户可以交互式地控制他们的视角（包括位置和旋转）。因此，VR内容的观众可能会把目光从电影创作者想要的场景上移开。这给这种新媒体的故事叙述设置了障碍。一个潜在的解决方案是禁用视点控制，以免失去沉浸感。本项目研究了VR电影视点控制中两个相互关联的问题。我们首先建议从对用户体验和沉浸感的影响角度来评估交互式与非交互式视点控制的优点。其次，我们将实证比较控制视角方向的机制，为VR电影制作者提供工具，帮助他们更好地理解和在电影中使用交互性。

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.
