Abstract
A method for determining the position of a contact on a panel envisages, during a detection operation, detecting vibration signals at a plurality of detection areas fixed with respect to the panel as a function of vibrations generated by the contact; determining detection values of temporal differences between times of detection of the vibrations at pairs of said detection areas; and determining the position of the contact as a function of said temporal differences. A characterization operation, preceding that of detection, envisages defining contact areas (key1-keyn) on the panel and associating to these contact areas respective ranges of admissible values for the temporal differences. In order to determine the position of the contact in a given contact area, the membership of the detection values of the temporal differences to the respective ranges of admissible values of the given contact area is verified. The method moreover envisages implementation of an algorithm for reconstruction and filtering of crossing signals, originated by the comparison of the vibration signals with one or more threshold values.
