Abstract :
We compare two different models that can be used to describe velocity profiles of a handwritten stroke. The theoretical analysis and performance comparison on the fitting data figures and the mean square error clearly reflects the superiority of the delta lognormal model over the minimum jerk model to describe the velocity profile characterizing rapid movements.
