在电影虚拟现实（CVR）中，全方位电影的观看者在观看电影时可以自由地选择观看方向。因此，电影制作中引导观众注意力的传统技术不能直接适应CVR。诸如平移或改变框架的做法不再由电影制片人定义;而是由观众决定看哪里。在某些故事中，有必要向观众展示某些细节，这些细节不应错过。同时，不应破坏观众在场景中环顾四周的自由。因此，需要将观众的注意力引导到场景中的视觉信息的技术。注意力引导也有可能改善一般的观看体验，因为观众在观看应用了注意力引导技术的全方位电影时将不那么害怕错过一些东西。近年来，关于图像、电影、虚拟现实、增强现实以及CVR中的注意引导已经有了很多研究。我们对这些方法进行了分类，并为注意力引导方法提供了一个分类。讨论了不同的特点，我们阐述了优点和缺点，给出了用例的建议，并将分类法应用于几个指导方法的例子。
In Cinematic Virtual Reality (CVR), the viewer of an omnidirectional movie can freely choose the viewing direction when watching a movie. Therefore, traditional techniques in filmmaking for guiding the viewers’ attention cannot be adapted directly to CVR. Practices such as panning or changing the frame are no longer defined by the filmmaker; rather it is the viewer who decides where to look. In some stories, it is necessary to show certain details to the viewer, which should not be missed. At the same time, the freedom of the viewer to look around in the scene should not be destroyed. Therefore, techniques are needed which guide the attention of the spectator to visual information in the scene. Attention guiding also has the potential to improve the general viewing experience, since viewers will be less afraid to miss something when watching an omnidirectional movie where attention-guiding techniques have been applied. In recent years, there has been a lot of research about attention guiding in images, movies, virtual reality, augmented reality and also in CVR. We classify these methods and offer a taxonomy for attention-guiding methods. Discussing the different characteristics, we elaborate the advantages and disadvantages, give recommendations for use cases and apply the taxonomy to several examples of guiding methods.
