How can you apply Fitts law in your daily life?

Fitts' law is widely applied in user experience (UX) and user interface (UI) design. For example, this law influenced the convention of making interactive buttons large (especially on finger-operated mobile devices)—smaller buttons are more difficult (and time-consuming) to click.

What are some implications of Fitts law?

The most obvious implication of Fitts's law is: make targets big. Fitts's law clearly says that people will be faster to click, tap, or hover on bigger targets. Not only that, but error rates go down as target sizes increases.

Does Fitts law apply to touch screens?

Fitt's law originated with physical controls. Touchscreens are proto-physical so it applies the same way.
