Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human–computer interaction and ergonomics. The law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. [1]
The impairment in force production is muscle specific. During dynamic exercise, the old group requires more time to reach a target velocity and is less able to attain high velocities. The slowing of voluntary contractile speed with age seems to play a role in the loss of dynamic torque.

Force control is the control of the force with which a machine or the manipulator of a robot acts on an object or its environment. By controlling the contact force , damage to the machine as well as to the objects to be processed and injuries when handling people can be prevented.
Command and control (abbr. C2) is a "set of organizational and technical attributes and processes ...[that] employs human, physical, and information resources to solve problems and accomplish missions" to achieve the goals of an organization or enterprise, according to a 2015 definition by military scientists Marius Vassiliou, David S. Alberts, and Jonathan R. Agre.
The Active Denial System (ADS) is a non-lethal directed-energy weapon developed by the U.S. military, [2] designed for area denial, perimeter security and crowd control. [3] Informally, the weapon is also called the heat ray [4] since it works by heating the surface of targets, such as the skin of targeted human beings.

Stopping power is the ability of a weapon – typically a ranged weapon such as a firearm – to cause a target (human or animal) to be incapacitated or immobilized. Stopping power contrasts with lethality in that it pertains only to a weapon's ability to make the target cease action, regardless of whether or not death ultimately occurs.
