摘要： This method for locating at least one touch on a touch-sensitive surface of an object comprises the following steps: monitoring (100) of at least one touch by propagating (102), in the touch-sensitive surface of the object, elastic mechanical waves from at least one transmitting point of the object, and by detecting (104) said elastic mechanical waves in at least one reception point of the object, in order to obtain at least one sensed signal, and locating (200) at least one touch on the touch-sensitive surface of the object by comparing certain spectral characteristics of the sensed signal to a set of reference characteristics. The monitoring step (100) comprises measuring (104, 106) the sensed signal during a time interval (t3 ) starting during a transient phase of the propagation of the transmitted waves, for supplying, to said at least one reception point, information on radiation interfered with by said at least one touch.
