Abstract: The invention relates to a method for determining the location of an impact on a surface of an object based on the analysis of an acoustic signal generated by the impact. This method further comprises a signal treatment step of weighting the acoustic signal to take into account spurious contributions in particular due to reflections at the border of the object.

Abstract: A touchsensing device for localizing mechanical impacts on a tactile plate, with at least one acoustic transducer mounted on the tactile plate by means of an acoustic isolator, such that the acoustic transducer and the tactile plate are in direct contact with each other and the acoustic transducer is acoustically shielded by the acoustic isolator. Thus, acoustic waves can be detected with little distortions and the reliability of the touch sensing device can be improved. Also, a touch sensing device having a tactile plate and a sensor module having at least one acoustic transducer and a fastener to fix the sensor module to the tactile plate, wherein the fastener is a sticky tape, in particular a double sided sticky tape.
