According to Fitts Law, how does the width of a target affect accuracy?

• A. Wider targets increase accuracy
• B. Narrower targets increase accuracy
• C. Width of target has no effect on accuracy
• D. Wider targets decrease accuracy

Answer: (A)

Fitts' Law describes the relationship between the distance to a target and the width of that target in determining the time it takes to complete a movement toward it. According to this law, wider targets are associated with increased accuracy because they provide a larger area for the individual to aim at, making it easier to successfully hit the target. This increased target width reduces the precision required in initiating a movement and allows for more successful attempts as there is less need for fine motor control. When targets are wider, the likelihood of successfully engaging with them increases, as there is more room for error in aligning one’s movements, leading to a higher success rate in tasks requiring accuracy. In contrast, narrower targets make it more challenging to achieve the desired outcome as they require more precise movements and finer motor skills. Thus, a wider target effectively enhances accuracy in performance tasks, which is a fundamental aspect of Fitts' Law.
