Question

In a bimanual Fitts' Task, if the right hand moves to a far target, and the left hand moves to a near target, what will the right hand do?

1) speed up to coordinate timing with the left hand
2) follow Fitts' Law
3) slow down to coordinate timing with the left hand

Answer 1

In a bimanual Fitts' Task, each hand moves according to Fitts' Law, which implies that the right hand moving to a far target will act based on the distance and target size without necessarily coordinating timing with the left hand.

Step-by-step explanation:

In a bimanual Fitts' Task, if the right hand moves to a far target, and the left hand moves to a near target, the right hand will follow Fitts' Law.

Fitts' Law predicts the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. In other words, movements to far targets tend to be slower due to increased distance and smaller targets require more precision, thus slowing the movement. Therefore, the right hand will not necessarily speed up or slow down to coordinate timing with the left hand; instead, each hand will move according to the parameters defined by Fitts' Law.
