Characteristics of eye tracking movement vary with the level of the attention of the subject tracking a moving target. The target brightness feedback (TBF) method was developed in order to enhance attention to the target. Sinusoidal target movement was used. The saccadic component was detected from eye movement data, and the four saccadic parameters, that is, the magnitude, the position errors at the start and end of saccade, and the adjusting gain, were obtained. The standard deviations of all parameters except the position error at the start of saccade decreased with the use of TBF, suggesting that saccadic characteristics become stable when attention is enhanced.>
