Fitts’s Law
Fitts's Law is a rule in interface design that helps predict how quickly a person can move a pointer, like a mouse or finger, to a target on a screen. When designing menus or buttons, placing important actions at the edges or corners of the screen can make them faster to reach, because the pointer can stop moving as soon as it hits the edge. This means that making buttons bigger or putting them in easy-to-reach spots can help people use interfaces more quickly and with fewer mistakes. Designers use Fitts's Law to decide where to put things like toolbars and action buttons so that people can work faster and feel more comfortable using digital products.
