1. A method of detecting a force-producing input from a user and providing a user-customizable haptic output, comprising:
- receiving the input at an input arrangement of a user interface, the input arrangement having at least one piezoelectric sensor;
generating, at the at least one piezoelectric sensor, an electric signal in response to the input;
processing the electric signal to determine a presence of the input, the processing including determining at least one of a voltage difference between a current signal sample and a previous signal sample and a rate of voltage change from the previous signal sample to the current signal sample;
recording a force and a timing interval of the input;
receiving a user selection of a haptic output to be generated in response to future instances of receiving the same input with a force and timing equivalent to the recorded force and the timing interval of the input; and
generating, at an output arrangement of the user interface, the haptic output in response to a processing of an electric signal generated in response to receiving the same input with a force and timing equivalent to the recorded force and the timing interval of the input.

Abstract
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.
