Abstract: A method for determining the locations of at least two impacts F1 and F2 on a surface using one or more sensors Si, i=1 to n, with n being the number of sensors, and the impacts F1 and F2 generating a signal being sensed by the one or more sensors, wherein each sensor provides a sensed signal si(t), i=1 to n, with n being the number of sensors. To be able to determine simultaneous impacts of different amplitudes the method includes identifying the location x of one impact, and determining a modified sensed signal si?(t) for each sensor in which the contribution due to the identified impact is reduced and which is based on a comparison, in particular a correlation, of each of the sensed signals si(t) and a predetermined reference signal rij(t) corresponding to a reference impact Rj at location j. The method can also be based on couples of sensed signals.
