That which is the means, mechanisms, and tools of interfacing to a machine system for ideal human and mechanizative use; Typical implementation utilizes a consistant spherical object (aka ballie) to computationally extrapolate 3D ballie position in free space using optical characteristics in imaging, namely circular contiguities within 2D images, be them photographic, digitized, or computationally produced, regardless of origin of such data. Ballies also refers to the abstract awareness of said ballie(s) both by intelligent beings and computational or mechanical machines alike. Multiple individual ballie existances facilitates analytic awareness of the context and qualities of abstract interpretation. Ballies are also standard balls used for such a purpose or existing within a context as defined.
Ballies compose and are the abstract composite of mutual understanding of contexts and qualities amongst diverse modes of understanding, especially between human and modern machine.
