Position of subject and targets and pictorial indication of spatial sound for one target. The position of the targets relative to a subject with right hemiparesis is shown. Six targets were positioned on the surface of the table and three were on a removable support. Targets were arranged on three lines (saggital and 30° to the left and to the right). Thick arrows indicate movement distance. The intensity and frequency of the sound in each ear depended on the direction and position of the hand relative to the target.
