Abstract
The invention relates to a method for determining the locations of one or more impacts or touches on a surface of an object including two or more transducers which improves the precision of localisation even for low signal to noise ratios and furthermore provides the possibility to identify multi touch or multi impact situations. To achieve these objects the method comprises the steps of: a) receiving a signal, in particular an acoustic signal, from each one of the transducers, wherein the signals correspond to at least one impact at least one location on the surface; b) determining a representative value based on the signals received in step a) and predetermined properties, in particular acoustic properties, of the object at a given location on the surface of the object; and c) deciding whether the at least one impact at the at least one location on the surface of step a) corresponds to the given location on the surface based on a comparison of the representative value and the corresponding value of the at least two signals.
