A Study of Eye Tracking Performance during Pursuit Object Motion in Television Images
A study to evaluate the eye tracking performance during pursuit object motion was conducted. An eye tracking system was used to measure eye-movements for several well-defined object velocities, assumed to be representative for typical broadcast television images. Simple test patterns moved either in horizontal or vertical direction with a uniform motion speed of 4, 8, and 12 pixels per frame (5, 10, and 15 degrees/second), while the eye tracking trajectories were recorded. The results demonstrate that eye tracking is not so smooth, eye tracking speed is not necessarily equal to the object speed, and saccades are necessary in order to maintain the moving object in focus. In the paper, we give a more detailed analysis of the eye tracking recordings, including the influence of pattern characteristics.
