Abstract
A process for detecting the physical positions or changes of position of a human being based on detecting a physiological signal dependent on a sympathetic/parasympathetic nerve system in each case in the heart or in a vessel near the heart by means of a sensor at pre-specified times, in particular, based in each case on a physiological or stimulation event, deriving a value of a signal parameter in each case, from this signal according to a pre-specified signal processing rule and stored determining a fluctuation curve of the stored signal parameter values, performing a frequency analysis of the fluctuation curve to obtain the spectral power density evaluating the spectral power density, resulting in the issuance of a position signal as a function of the evaluation result, whereby the morphology of the signals is detected and the value of the signal parameter is, in each case, derived from morphology of an individual detected signal.
