     σ, where:
p is a detection probability density;
σ is a standard deviation of a vibrotactile stimulus that represents signal strength;
τσ is an acceleration threshold of the standard deviation; and
θσ is the standard deviation of normal distribution that controls a slope of detection probability variation.
