This study aims to sharpen the evaluation of the role of head position in accuracy of aiming and encoding the target location. An aiming task was performed in order to provide a precise measure of directional errors. The errors are assumed to the encoding of gaze direction and to the head and eye signals. The pure aiming task helped in the analysis of the direction and amplitude components in the programming of an aiming reaction. The study focuses on the need to take into consideration the division into subgroups of the population with different reaction modes and strategies.

Keywords: gaze direction, aiming task, directional errors, head position, amplitude components
