Abstract
The invention relates to an electronic device with a touch sensitive surface comprising: a sensing means for capturing an acoustic signal, a touch location determining unit configured to determine the location of a touch event on the touch sensitive surface based on the acoustic signal. To improve the reliability of the touch localization process, the device further comprises a filtering unit configured to improve the signal-to-noise ratio of the acoustic signal based on one or more signals provided by one or more spurious acoustic signal generating devices of the electronic device and/or based on one or more parameters of the one or more spurious acoustic signal generating devices of the electronic device. The invention also relates to a corresponding method. The invention furthermore relates to a method for improving the confidentiality of a user input.
