Fitts' Law

Fitts' Law is a principle in human-computer interaction that predicts how quickly a person can move to a target, like a button on a screen. It states that the time it takes to reach a target depends on the distance to the target and its size. Smaller or farther targets take longer to reach, while larger or closer targets are easier and quicker to hit. This law helps designers create intuitive interfaces by ensuring important buttons are appropriately sized and positioned for efficient interaction, enhancing user experience and productivity.
