                         to enhance current computer interfaces. In this paper we present 
                         an eye gaze tracking system based on a robust low-cost-real-time 
                         pupil detector, and describe some eye-aware applications being 
                         developed to enhance HCI. Pupils are segmented using an active 
                         lighting scheme that exploits very particular properties of eyes. 
                         Once the pupil is detected, its center is tracked along with the 
                         corneal reflection (CR) generated by the light sources. Assuming 
                         small head motion, the eye gaze direction is computed based on the 
                         vector between the centers of the CR and the pupil. after a brief 
                         calibration procedure. Other information such as pupil size and 
                         blink rate can also be made available. The current prototype runs 
                         at frame rate, providing 30 samples of the gaze position per 
                         second to all gaze-aware applications, such as advanced pointing 
                         and selection mechanisms.",
