Acceleration of pen-movement during the signing process.
This feature is used for on-line signature verification. There are two ways to obtain the acceleration feature. One way is to measure the pen acceleration directly with accelerometers integrated into the pen. The other way is to compute the acceleration from other measurements, for example, from the second-order derivative of the pen position signal with respect to time.
