Abstract
Input force applied on a pointing device (51) having outputs (x,y) is related to the velocity of a cursor on a video screen according to a transfer function (FIG. 2) substantially described by a parabolic sigmoid function, thus resulting in adapting the force/velocity relationship to accommodate human perception and motor control limitations and task specific coordination problems.
