where x(t), v(t) and a(t) are the two dimensional-components
of the position, velocity and acceleration of the tracked point, and na(t)
is additive zero-mean, Gaussian, white noise. The state of the filter X(t)
includes three 2-dimensional variables x(t), v(t) and a(t).
This model is a second order model that is appropriate to describe the

MODEL OF THE PEN TIP
The model that we are currently using is a second order model that
is appropriate to describe the dynamics of a point object moving on a plane.
The following figures shows the differential equations that describe the
output of the model y(t) is the estimated position of the pen
