6 hours ago Fitts’s Law is about how long it takes to move your hand to an object. This Law states exactly how the time it takes is a function of the combination distance to the object and its size.

8 hours ago FittsLaw 351 With ID in bits and MT in seconds, TP has units bits per second or bits/s.A central thesis in Fitts’ work is that throughput is independent of movement amplitude and target width, as embedded in ID.In other words, as ID changes (due to changes in A or W), MT changes in an opposing manner and TP remains more‐or‐less constant. Of course, throughput is expected to be

1. Most treatments of Fitts' Law say WHAT is true, but not WHY. However, if one understands why it is easier to predict where it will hold and where fail. Whilst Fitts' original paper uses an analogy with Shannon and Weaver's information theory, it does little more than postulate some neurological information rate. In fact it is easier to understand Fitts' Law if one considers the control task of hand-eye coordination. This is an interaction - one moves the mouse (or other pointer), the eyes see the movement, you correct etc. This all happens in a fraction of a second. Timing is critical as the delay between seeing something, the processing to be done in your brain and the signal to get down your arm to your muscles is between 150 and 200 milliseconds. Your arms moves a long way in that time, typically 70-90% of the way to the target. This is rather like controlling one of those Mars robots where the transmission delay can be 20 minutes or even more when Mars is further away. You could...

### How do you use Fitts' law in tapping?

The participant taps between two targets of varying width (W) and with varying amplitude between them (A), attempting to move as rapidly as possible while keeping the number of target misses to a minimum. Fitts' Law states that MT is constant whenever the ratio of the movement amplitude ( A) to target width ( W) remains constant.
