Abstract
A method for providing corrected measurements of absolute capacitance of an object in the proximity of at least two independent electrodes of a non-optimized shape integrated in a human-machine interface device for detecting the object. The method includes measuring, for each electrode, an actual value of absolute capacitance between the electrode and the object, and calculating a prediction by applying a multi-variable nonlinear prediction model to the actual values of absolute capacitance so as to obtain an image of probability densities. Then, using the probability densities as corrected absolute capacitance values for detecting the object.
