<p>A method is provided for absolute capacitive measurement of an object relative to at least two hide—pendent electrodes integrated into a man-machine interface device for detecting the object. The method includes: a) for each electrode, a value of absolute capacitance between the electrode and the object is measured, a′) a prediction is made by applying a multi-variable nonlinear prediction model to the actual values of absolute capacitance to obtain an image of probability densities, these probability densities considered to be actual corrected values that are used for detecting the object. The multi-variable nonlinear prediction module is optionally obtained by nonlinear regression on the basis:—of actual values of absolute capacitance that are obtained for a plurality of object positions relative to the at least two electrodes, and—of an image of probability densities that is obtained for a plurality of object positions relative to idealized electrodes.</p> |
