A method for touch detection includes identifying a high-pass filtered sequence from a plurality of sensor measurements, accumulating a number of samples from a first high-pass filtered sequence into an accumulated value, comparing the first accumulated value against a threshold of accumulated values, and, based upon a determination whether the accumulated value is greater than the threshold of accumulated values, identify whether the sensor has been approached.

Water robustness and detection on capacitive buttons

A method for detecting a continuous circular gesture performed by an object, may have the steps of: detecting a movement of an object performing a circular movement by scanning the movement and determining subsequent position points of the object, wherein a reference position of a virtual circular movement is adapted depending on the history of scanned position points.
