No suspense in this blog. The cardboard needs two cameras for eye tracking, connected to the mobile phone plus a special app modified to work with rich data video recordings. And it needs a new type of movie directors which are willing to release some control to the viewers where it makes sense.
There has been some standard in the movie industry since its inception which new technologies are allowing to break. What I am referring to is the predefined static frame of the scene, and the predefined aperture and focal plane.
It is important to understand that these are static and predefined from the viewers point of view. A good example is a typical scene of two people having an interesting conversation and the focal plane moves from one to the other to direct the viewers eyes.
I as a viewer would like to bring the focus back to the first person even though the director wants me to concentrate on the second one. I can hear the second person speaking but the first character interests me more. This is were the eye tracking takes a place. I would also like to be able to pan outside this scene (as much as I am allowed in a VR fashion). This perhaps works well in a Sherlock Holmes movie.
8K cameras are hitting the market, Shoot your movie in an 8k and allow us to navigate a little where it makes sense. Allow us to move forward, backward, to the left and to the right. Now add to the 8K capture additional light field vector data and you get yourself a flexible scene allowing us as viewers to slightly change the angle of view of the scene as well as the focal plane. Again, with the permission of the director.
How does this permission work? Every scene should be tagged with viewers capabilities data. These data will include the total size of the frame which could be larger than the viewport, the depth of the focal plane, and the degree of viewing angle the viewers are allowed to navigate. The director will specify these parameters to the scene. Should the director decide to be strict and tighten up the scene, then we are back to the old days of passive movie watching.
