Method of capacitive measurement by non-regular electrodes, and apparatus implementing such a method

. . The invention relates to a method of absolute capacitive measurement of an object with respect to at least two independent electrodes integrated into a man-machine interface device for detecting said object. This method comprises the following steps: 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 so as to obtain an image of probability densities, these probability densities being considered to be actual corrected values that are used for detecting said object. ...
