Claim One:
1. A method comprising: (a) during a first session of a user who utilizes a pointing device for interacting with a computerized service, monitoring on-screen movements of an on-screen pointer; (b) analyzing the on-screen movements of the on-screen pointer to derive from them estimated dynamics and gestures of the pointing device as utilized by said user; (c) defining a sensorimotor control loop model by utilizing at least a function that takes into account at least (A) a first trajectory parameter indicating current velocity of pointing device movement, and (B) a second trajectory parameter indicating translation error; (d) by analyzing the estimated dynamics and gestures of the pointing device, determining (AA) at least one sensorimotor control loop parameter that characterizes utilization of said pointing device by said user, and (BB) at least one parameter corresponding to a noise characteristics of the sensorimotor control loop that characterizes utilization of said pointing device by said user; wherein said determining comprises: generating a function that describes the sensorimotor control loop model that causes said on-screen movements of said on-screen pointer; (e) differentiating between (i) said user and (ii) one or more other users, based on (AA) said at least one sensorimotor control loop parameter that characterizes utilization of said pointing device by said user, and (BB) said at least one parameter corresponding to the noise characteristics of the sensorimotor control loop that characterizes utilization of said pointing device by said user.
