System, method and computer program for detecting an object approaching and touching a capacitive touch device

A method for detecting an object approaching and touching a capacitive touch device of a detection system, said detection system comprising also:

• a processor, and
• an optical system connected to said processor and arranged to collect information on said object,
• said method comprising the following steps:
• classify the object as a triggering object or as a non-triggering object based on said information from said optical system,
• if the object is classified as a non-triggering object, disable the execution of touch functions of the capacitive touch device at the latest when at least a part of the object touches the capacitive touch device, said disable being performed at least in the zone of contact between the capacitive touch device and the non-triggering object,
• 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, execute a predetermined function on said capacitive touch device depending on said information.
