2123813 9311506 PCTABS00022 The data input device (11) comprises, above a resistive layer arrangement (2), an arrangement (4) of deformable layers consisting at least partially of dielectric material. This material is elastically deformable so that, when pressure is applied onto the input surface, the distance between the input surface and the resistive layer arrangement (2) is reduced at the pressure point. On the side of the deformable layer arrangement (4) facing away from the resistive layer arrangement (2), there is arranged an electrode which preferably is formed as a conductive layer (1). Thus results in a change of the capacitive properties of the deformable layer arrangement (4) at the pressure point since the thickness of the deformable layer arrangement (4) is reduced on this site. This capacitive measurement is used for detection of the pressing force, while the position of the pressing point within the input surface is detected in two mutually orthogonal directions on the basis of the voltage divider forming in the resistive layer arrangement (2).
