Abstract
Official abstract text for this publication.
The invention relates to a method for determining the location and duration of a sustained contact of a touch event performed by a user on a surface of an object comprising the steps of: a) determining the location of the touch event, in particular based on an acoustic signal generated by the impact of the touch on the surface, and b) determining the duration of the touch event based on a perturbation of a signal generated in or on the object by a transducer characterized in that step b) comprises analyzing the signal generated at or close to N natural frequencies of the object, with N being one or more. The analysis close to the natural frequencies allows the reliable determination of not only the location of a touch event but also whether the user continues to interact with the surface of the object which is due to the important damping of the generated signal in the presence of the touch. The invention also relates to a touch sensitive device configured to carry out the method.
