Photographic 360°-techniques have by now come to widespread attention. The subject itself is relatively old, but has been considerably promoted through Googles StreetView-project in particular.
Spherical videos have a different basis. The 360°-perspective is not composed of a certain number of pictures anymore. It now has videos as the starting point for the programme-based blending-together of the source material
This approach neatly resolves the two main shortcomings on the photographic level:
1. The 360°-photography allows the user to control the perspective (or line of vision), but it and he remain locked within a circle of static content (or more precisely: in a sphere of static content).
2. The reference frame of a 360°-picture is by definition limited to one position only. This leads not only to the exclusion of moving content, but in particular to not being able to represent the viewer’s own movement (including their changing observational sphere).
Stepping back from a purely analytical viewpoint it is probably better to have an unbiased look at the effects involved. We were very impressed by the spherical videos, because they come very close to actually walking through the rooms in person. It seems we have reached a completely new level in emulating our natural environment.
Does the observer walk trough the apartment him-/herself? Or is it rather that the space observed has learned to walk around? We do not want to exaggerate, however. Even if according to Einstein both perspectives must be very similar indeed.
