Question

Does Fitts's law inherently portray mouse usage as inefficient?

Hotkeys are direct event initiators, mean while using a mouse requires excessive navigation to a event initiator, or does mental processes reduces keyboard efficient due number of keys?

(If someone does end up replying to this please note that I will be citing you in a paper.)

Answer 1

Seems like a rhetorical question. Of course, yes.

Answer 2

So would the number of keys influence whether mouse usage is more or less efficient, or is it always constant?

Answer 3

lol ..bruh

Answer 4

Erm, slight addition, does anyone know how one would calculate variable limitation, or do I just average it in a formula?

Answer 5

> Does Fitts's law inherently portray mouse usage as inefficient?
TL;DR it depends. (And Fitts's law does not apply to keyboard usage at all, but works great in determining when GUI beats keyboard.)

Mouse navigation is concurrent, eyes are locked to one element on screen (the cursor). Keyboards, are slower because one has to find the proper key out of numerous characters. (So technically they are not direct event initiators.)

Speaking that we measure in logarithmic units, as more key binds there are the more complexity there is; however, complexity reduce as the human learns via muscle memory. (And they finally become direct event initiators.)

So in the start humans will benefit from GUI, point-click based navigation, because they lock to one element. However, key binds, (e.g. keyboard navigation) become more efficient as one learns the muscle memory of where things are located on their keyboard.

I am leaving this open if anyone is still interested in contributing anything as the paper is not near being published.
