A capacitive sensing system ( 200 ) can include a sense section ( 202 ) and a filter section ( 206 ). Sense section ( 202 ) can activate logic outputs based on a sensed capacitance from sensors ( 210 - 1 and 210 - 2 ). A filter section ( 206 ) can logically combine logic outputs in different ways to generate output signals (INT<SUB>-</SUB> 1 and INT<SUB>-</SUB> 2 ). According to output signals (INT<SUB>-</SUB> 1 and INT<SUB>-</SUB> 2 ), different types of movement in a capacitive body ( 212 ) can be detected.
