Fitts's law

Fitts's law is a way to measure how easy or hard it is to click on something on a computer screen or a device. It says that the easier it is to click on something, the less time it will take you to do it. It also says that the bigger something is, the easier it will be to click on it. So if you have a button on a computer screen that you want to click, make sure it is big enough for you to click on easily!
