| dcterms.abstract | This thesis presents a design methodology of a low-cost noninvasive gaze tracking system to detect gaze behavior when user is browsing internet or reading material on computer. The user's face image is captured and processed in real-time. By means of C++ and OpenCV library, the system detects face, eye region with Haar feature-based cascade classifier. Eye center is detected by contouring dark area in eye region and finding the center of largest area among contoured dark areas. The detected eye center is mapped to gaze point on computer screen after four point calibration. The average angular error is 1.96 degree, which is comparable to other proposed techniques. During the experiment, the gaze point is displayed real-time with eye movement, and its coordinate as well as the gazed object are recorded in file. The system represents image information in unit area, object, scene, and frame hierarchy structure. With the gaze point data and image information, it is able to analyze gaze duration among objects and understand user's gaze behavior. | |
