Abstract or description

To accurately examine and compare Digitally Captured Signature data, the provided data channels (X, Y, F and T) need to be expressed in comparable units. The Force channel data is routinely expressed in unnormalized Pressure Levels hindering the accurate comparison between data collected from different devices. The normalization method using the Zeta Function is used to calibrate and calculate the Zeta Functions of the Wacom DTU1141b.
