Method and device for detecting user input

摘要

A method and a device for detecting user input includes receiving a user input at an input arrangement of a user interface. The input arrangement has at least one piezoelectric sensor that generates an electric signal in response to the input. The electric signal is processed to determine the presence of the input. The processing may indicate the magnitude of the force of the input, in addition to the input's location. An output arrangement of the user interface generates an output in response to the processing. The output may be a haptic, audio or visual output.
