Fitt's Law
Commented on:

Paul M. Fitt's law is has been remarkably true for many different applications. The law, which models human movement, predicts the time it takes to reach a position. The target time to reach a target location is calculated by the following equation(formulated differently than presented in paper):


T: average time of movement
a: start/stop time of device
b: inherent speed of device
D: Distance from starting point to target
W: width of target

Overall, the law states that the time it takes to reach a target area is proportionate to the distance of width of the target. So, it would take the same amount of time, given the correct ratio, to reach a destination, if the target was a wide, but the distance of was long, or the target was narrow and the distance was short. This law has been proven to hold true to many things, and I think is pretty fascinating.
