Abstract

A contact sensitive device comprises a member (12) capable of supporting bending waves, three sensors (16) mounted on the member (12) for measuring bending wave vibration in the member, whereby each sensor (16) determines a measured bending wave signal and a processor which calculates a location of a contact on the member from the measured bending wave signals. The processor calculates a phase angle for each measured bending wave signal and a phase difference between the phase angles of least two pairs of sensors so that at least two phase differences are calculated from which the location of the contact is determined.
