7), the indexes have been computed on the gray level images (from 0 to 255), for the sake of simplicity. by a torsional rotation matrix: The complete rotation of the view-volumes is described by the following relation: where the subscript L2 is used to indicate that it is Listings law compliant matrix. For the simulations shown in the following, we first captured 3D data from a real-world scene of the peripersonal space, by using a 3D laser scanner. L Copy to clipboard. The dataset presented in this paper is meant to mimic the actual 6 degree-of-freedom eye pose of an active binocular visual system in peripersonal space, i.e., with camera pose exhibiting vergence and cyclotorsion as a function of the gaze direction16, (i.e., direction from camera to fixation point).

In each of the vantage points, the head was then put at a fixed vergence distance of 3 (=155cm) from the closest object along the nose direction. is composed of rotations about the horizontal and vertical axes, only, the resulting head pose is characterized by no torsional component, according to the kinematics of the Fick gimbal system. Considering a human observer, the complete 3D pose of a single eye is defined (limited) by the Listings law (LL), which specifies the amount of the torsional angle with respect to the gaze direction105.
