Abstract
Se usa una transformada para transformar datos de sensor capacitivo brutos del dominio de tiempo al dominio de frecuencia o secuencia. Los datos transformados caen en varios compartimientos de señales. Los datos transformados en al menos uno de los compartimientos de señales se analizan para determinar si se ha producido un evento táctil o evento de liberación.
