Abstract
A system (1) detects an object (100) approaching and touching a capacitive touch device (10). The system includes the capacitive touch device (10), a processor, an optical system connected to the processor and arranged to collect information on the object (100). The processor is arranged so as to classify the object (100) as a triggering object or as a non-triggering object based on this information. If the object is classified as a non-triggering object, the processor disables the execution of touch functions of the capacitive touch device (10) at the latest when at least a part of the object (100) touches the capacitive touch device (10). If the object is classified as a triggering object, at the latest when at least a part of the object touches the capacitive touch device (10), the processor executes a predetermined function on the capacitive touch device (10).
