Fitts's law: draft of target size W and distance to target D. 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 ...

This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a ...
A pointing stick (or trackpoint, also referred to generically as a nub, nipple or clit) is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice, touchpads or trackballs, operating system software translates manipulation of the device into movements of the ...
In general, ergonomic keyboards are designed to keep the user's arms and wrists in a near-neutral position, which means the slant angle (the lateral rotation angle for the keys in each half relative to the axis of the home row in a conventional keyboard) is approximately 10 to 12.5°, the slope (the angle of the keytop surfaces starting from the front edge closer to the user towards the top of ...
