Abstract
A system detecting actuation of a pre-determined function, the actuation executed by touch contact with a pre-determined path associated with the function on a touch-sensitive surface of an object, including: at least two separate sources for transmitting bulk acoustic waves in the touch-sensitive surface, configured to generate acoustic interference between the transmitted waves; at least one bulk acoustic wave receiver after propagation and interference thereof in the touch-sensitive surface, configured to supply a reception signal based on the acoustic waves received; a mechanism storing plural reference spectral signatures associated with the pre-determined path, each of the spectral signatures associated with a localization of a touch on the pre-determined path; and a mechanism detecting actuation of the pre-determined function by comparing at least one spectral signature of the reception signal to a spectral envelope, or reference spectral envelope, of the plural reference spectral signatures associated with the pre-determined path.
