Abstract
Denne oppfinnelsen angår en fremgangsmåte for bestemmelse av hastigheten til en overflatestruktur, særlig på et fingeroverflate, som beveger seg relativt til to i bevegelsesretningen plasserte sensorer, hvilke sensorer har en forutbestemt innbyrdes avstand og der sensorene måler variasjon i en forutbestemt egenskap ved overflate - strukturen. Fremgangsmåten kjennetegnes ved gjentatte målinger av fingerover- flatens egenskap og beregning av posisjonen til minst en ekstremalverdi, dvs maksimums- eller minimumsverdi, langs tidsaksen for hver sensor, og basert på disse posisjonene i tillegg til den kjente avstanden mellom sensorene beregning av overflatens hastighet i forhold til sensorene.
