The interaction between horizontal and vertical eye-rotations in tracking tasks
The interaction between vertical and horizontal tracking was investigated by using a two-dimensional target motion consisting of a sinusoid in one of the directions vertical or horizontal, and low-pass filtered Gaussian random sequences of variable bandwidth (and hence information content) in the or...

Abstract | The interaction between vertical and horizontal tracking was investigated by using a two-dimensional target motion consisting of a sinusoid in one of the directions vertical or horizontal, and low-pass filtered Gaussian random sequences of variable bandwidth (and hence information content) in the orthogonal direction. It was found that the presence of the random sequences reduced the efficiency of the sinusoidal tracking. However, the sinusoidal tracking was only slightly dependent on the bandwidth of the random sequences. Thus the system should be described as consisting of two independent channels with a small amount of mutual cross-talk.
