Abstract

Una transformada se usa para transformar datos de sensores capacitivos sin procesar del dominio del tiempo al dominio de frecuencia o secuencia. Los datos transformados caen en varios intervalos de señal. Los datos transformados en al menos uno de los intervalos de señal se analizan para determinar si se ha producido un evento táctil o un evento de liberación.
