1. A non-transitory computer-readable medium encoded with instructions configured to control a processor of an arousal measuring device to perform a method comprising:

  • receiving galvanic skin response signals in the processor of an arousal measuring device from a galvanic skin response sensor of the arousal measuring device;

    calculating a third or higher central moment of a galvanic skin response signal, wherein the third or higher order moment comprises at least one of;

    a skewness and a kurtosis;

    estimating at least one of;

    a level of arousal or a change in the level of arousal, wherein said estimation of the level of arousal is based on said calculated third or higher central moment exceeding a corresponding one of a plurality of threshold values, and wherein the estimation of the change in the level of a arousal is determined when one of;

    an increase in the level of arousal is determined when at least one of;

    a relatively low skewness or a relatively high kurtosis is calculated, ora decrease in the level of arousal is determined when at least one of;

    a relatively high skewness or a relatively low kurtosis is calculated; and

    outputting a signal to a user perceivable interface when one of;

    a level of arousal or a change in the level of arousal are estimated.
