Abstract (en)

[origin: EP0825573A1] The method involves evaluating a detected signal change based on the steepness of the produced signal curve. An area of the steepness is pref. associated with a movement sequence, and a voltage rise is pref. associated with the signal, which lies within the determined steepness. A difference between a momentary steepness value and a steepness limit is pref. used as first criterion, an excess of a minimal signal rise from an actual voltage rise is pref. used as second criterion, and the actual change is evaluated, using a microprocessor, as a detected movement only if both criteria are met.
