A system for inputting graphical elements Includes a substantially pen-shaped peripheral device (PD); means (DIG) for digitizing graphical elements produced by a first end (END1) of the peripheral device (PD); and display means (DISP) suitable for displaying the said graphical elements produced. The system also includes means (MSR) for measuring signals representative of the movement executed by the peripheral device (PD), which includes a gyrometer (G) with at least two measurement axes providing angular speeds according to the said axes, linked in a fixed manner to the said peripheral device (PD). Means (POS) for positioning, on the display means (DISP), a pointing element (PT), based on the said angular speeds, is also provided, together with means (ACT) for activating/deactivating the positioning means (POS).
