Abstract

An integrated circuit (400) for processing a signal from a pointing device sensor comprises an input (414) for receiving the signal; a signal processing circuitry (404) for detecting a feature in the signal indicative of a touch or click; and decision circuitry (408) for establishing whether a time interval between a first touch or click detected by the signal processing circuitry and a second touch or click detected by the signal processing circuitry is not longer than a maximum time interval. The pointing device sensor may be comprised in a touch screen. Additional circuitry (410) for extracting coordinates representing a position where the touch screen is touched; and circuitry for detecting a feature in the signal indicative of a touching movement along the touch screen is provided.
