Abstract
Official abstract text for this publication.
The present invention relates to a method for determining an acoustic response attributed to a location of an impact, in particular a touch event, on a surface of an object including at least one transducer comprising the steps of: Injecting a predetermined acoustic bending wave by the transducer at the transducer position ( 5 a , 5 b ), Sensing a bending wave parameter at a secondary location ( 11 ) on the surface different to the transducer position, determining the acoustic response based on the sensed bending wave parameter and properties of the predetermined acoustic bending wave effectively as if the injection took place at the at least one secondary location ( 11 ) on the surface different to the transducer position and the sensing took place at the transducer position based on reciprocity principles, and determining the acoustic response attributed to at least one location ( 9 ) on the surface different to the at least one secondary location ( 11 ) on the surface different to the transducer position based on at least two different acoustic responses determined in step c).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for determining an acoustic response attributed to a location of an impact, the method comprising: a) injecting a predetermined acoustic bending wave by at least one transducer at a transducer position on a surface of an object; b) sensing a bending wave parameter at a secondary location from among a plurality of secondary locations on the surface, the secondary location being different to the transducer position; c) determining a first ac…
