Abstract
A device for detecting the presence of an object is provided. The device includes a light source, a current controller coupled to the light source, a sensor and a pattern detection engine. The current controller sets to provide the light source with a drive current having a pattern. The sensor is operable to receive light, notably light reflected from an object at the detection area and subsequently generates a signal in response to the light received. The pattern detection engine receives the signal from the sensor and subsequently reports the presence of the object upon determining the presence of the pattern in the signal. The object detection system is further configured to provide a navigation operation when an object is detected at the detection area.
