Abstract

Un dispositivo electronico (100) incluye cuando menos L teclas (114) y un procesador (506) que tiene cuando menos M entradas (600). Al accionarse, cada una de las cuando menos L teclas (114) palanquea una combinacion unica de N entradas de las cuando menos M entradas (600), en donde cada combinacion unica se toma a partir de todas las combinaciones posibles de las mismas. Las cuando menos M entradas (600) son leídas por el procesador (506), y se compara con una pluralidad de patrones de teclas previamente determinados (806). Cuando hay una concordancia entre las cuando menos M entradas (600) y uno de la pluralidad de patrones de teclas previamente determinados (806), se detecta un accionamiento de tecla, y se puede procesar una funcion previamente determinada en simultáneos en donde se palanquean combinaciones de entradas mayores que N.
