Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: ,  propose a high-performance, ultrasonic sensor-based head movement detection system, which can be easily applied as an eye tracking device by rotating a mirror set in front of a video camera in a head-free video-based eye-gaze detection system.  propose a simple distance measurement method that uses an A-D converter and an envelope detection method. Experimental results indicate small standard deviations of 0.4-0.8 mm (0.10% S.D.) when the distance beten the transmitter and the receiver is within the range of 40-80 cm. In addition,  arranged three transmitters on the apices of a triangle to simulate the head of the user. The receivers re arranged on the apices of a larger triangle. The coordinates of each transmitter re determined using the measured distances from the transmitter to the three receivers. The center of gravity of the three transmitters and the normal vector of the plane that includes the three transmitters re calculated based on the estimated coordinates of the three transmitters. The results indicate sufficiently high precision and measuring frequency for our purpose. The proposed method would be useful for adjusting the focus of a zoom lens to the eye, as ll as adjusting the direction of the mirror to the eye.
