Perceptual Inertial Frame (PIF)
Perceptual Inertial Frame (PIF) – In practice, this concept is similar to other philosophical concepts such as lebenswelt, umwelt, or niche in that it refers to the world as it is experienced by some subject. The perceptual inertial frame of a child is different from that of an adult, as would any age or social position have its own set of stereotypical qualities. Eigenmorphism describes how dissimilarity by scale, morphology, or history is a determining factor in how any given PIF presents every other PIF. This is roughly analogous to how optics can predict the anamorphic reflection of a reflective cylinder or the distortion of a fisheye lens. Tying in occasions of perception to the physics concept of inertial frames, the PIF model provides a framework for connecting universal and physical ontology to local experiential scope and quality, and it provides a possible scientific basis to investigate that connection further.
