Consistent with an example embodiment, here is a system for selecting the speed of a pointer on a display. The system comprises an analog input device arranged to generate an analog output signal (Vout), the analog input device suitable to be activated during an activation time (t). A signal processing means is arranged to select, depending on the activation time (t), a conversion function (f) for converting the output signal (Vout), the conversion function being different for different activation times, so that the converted output signal determined the speed of the pointer on the display. The speed of the pointer icon on the screen is both dependent on the time, t, and dependent on the output signal, Vout, of the analog input device itself, i.e. the pointer speed is a two-dimensional function f(t, Vout). |
