The interfaces presented use computer mouse, joystick or a stylus in conjunction with a touch screen as possible input devices. Control with a joystick offers two possibilities: In Nagel's case, the joystick position indicates the pointer position in the 2DES, taking advantage of the fact that one automatically moves back to the zero point. It is also possible that the joystick position corresponds to the movement speed and direction or the acceleration. Thus, if one moves the joystick towards the zero point, the pointer stays where it is and does not move to the zero point as well (Kopiez et al. 2011, p. 154f.). Whether mouse or joystick mediates better between test person, their desired position and the way to get there is certainly also related to personal experience with one or the other input device. Someone who has never used a joystick before may cope better with the mouse, even though the joystick may be more intuitive to use. The use of a touchscreen, however, makes it possible to dispense with this mediation completely and select the point directly in the image. Especially for subjects who are less used to using computers, this can help to reduce the barrier of the interface and prevent biased results to some extent. An interface for the iPad could be superior to the pARF in that the touchscreen is large enough to no longer require a stylus as an aid.
