The present invention relates to a proximity detection system and method for a computer or similar device. The computer includes at least two transducer units being capable of transmitting acoustic signals identifying the transducer within a predetermined frequency range. The transducer units are positioned at a distance from each other in said device, and at least one receiving transducer is capable of receiving acoustic signals within said frequency range and recognizing the transducer identification. The system is configured to measure the distance between each transducer unit and a reflecting object based on the transmitted and received signals based on the measured propagation time. The system is further configured to activate each of the transducer units and comparing the measured distance from each transducer unit thus calculating the direction of a reflecting object, and at the detecting of an object within a predetermined range of direction providing an activation signal to the device.
