Abstract: In a method for detecting people on a floor, at least three electrodes are integrated into the floor of the room that is to be monitored. Respective measurement axes are taken into account and associated with multiple pairs of electrodes integrated into the floor. The detection method includes the following steps: for each pair of electrodes, measuring a capacitance between the two electrodes of the pair; positioning a measurement point in a coordinate system defined by N of the measurement axes at coordinates provided by the capacitances measured for the pairs of electrodes respectively associated with the N measurement axes, where N is a number greater than 1; and detecting whether a person is lying on the floor according to a detection criterion that is function of the position of the measurement point in the coordinate system.
