Abstract
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.--1 and INT.sub.--2). According to output signals (INT.sub.--1 and INT.sub.--2), different types of movement in a capacitive body (212) can be detected.
