Patent number: 8351659Abstract: An eye detection system, method, and apparatus are disclosed. The eye detection apparatus includes illuminator, receiver, processor, and memory elements. The illuminator emits radiation at predetermined wavelengths from the eye detection apparatus toward an area of interest. Radiation from the area of interest is detected at the receiver which, in turn, provides sensor data to the processor. The processor is coupled to the illuminator and receiver and controls their respective operations. The processor detects a pattern representative of a human eye in the sensor data and determines coordinates of an object corresponding to the pattern. The memory stores the coordinates of the object.
