“…In the future, we would like to explore options to minimize this, for instance by creating a non-linear mapping between the head and the camera movement that prevents the viewer from moving too far. Alternatively, existing techniques for controling user attention in VR [17,30] could be helpful in this context. Last, as a consequence of the omnidirectional stereo (ODS) format, depth information near the poles is not accurate [55], and thus the performance of our method worsens near those regions.…”

Fig. 1. We add parallax for 360 • videos, for viewing in virtual reality head-mounted displays (HMDs). This translates into a more compelling viewing experience, as our user studies confirm. Left: Captured point of view as shown in the HMD (top), and a novel view as the user moves their head (bottom); this novel view is generated with our method and was not captured by the camera. Right, top row: Straightforward approaches based on image-based rendering do not work well due to suboptimal quality of the depth information. Original view (left) captured with the GoPro Odyssey, and a close-up of novel views generated with three different methods (right): (A) naive reprojection of RGB information, (B) naive handling of disocclusions, and (C) our method, relying on a robust layered representation. Right, bottom row: We also propose a depth map improvement step to correct for errors that have a high impact on reprojection. Original view (left) from a YouTube video (https://youtu.be/iWyvlkWYXhY), and close-ups showing depth maps and a displaced view computed with them, for the original estimated depth map (top row), and for our improved depth map (bottom row).

“…The same method was investigated for guiding in narrative art, with static images [62]. Grogorick et al extended this method to virtual environments [61]. A luminance modulation was used and a circle shape was dynamically adapted to ellipses for the wide FoV in VR.…”

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.

“…Grogorick et al [9] optimized and evaluated subtle gaze guidance by smoothly altering the luminance of the region of interest. This guidance is removed once the gaze tracking indicates the user looks towards the target.…”

“…To strike this balance, we aimed to make them subtle, i.e., non-intrusive, but also clear enough so that the guidance is separate from the environment (non-diegetic). Therefore, conventional or otherwise highly visible interface elements, such as arrows or pictures on the display [19,20], were not considered, and also, guidance methods with a more subconscious design [9] were not considered.…”

Viewing 360 • videos on a head-mounted display (HMD) can be an immersive experience. However, viewers must often be guided, as the freedom to rotate the view may make them miss things. We explore a unique, automatic approach to this problem with dynamic guidance methods called social indicators. They use the viewers' gaze data to recognize popular areas in 360 • videos, which are then visualized to subsequent viewers. We developed and evaluated two different social indicators in a 30-participant user study. Although the indicators show great potential in subtly guiding users and improving the experience, finding the balance between guidance and self-exploration is vital. Also, users had varying interest towards indicators that represented a larger audience but reported a clear desire to use the indicators with their friends. We also present guidelines for providing dynamic guidance for 360 • videos.
