Fitts’ Throughput Vs Empirical Throughput: A Comparative Study
AbstractEvery time a user taps on an element on a screen, she provides some “information”. Classically, Fitts’ law accounts for the speed accuracy trade-off in this operation, and Fitts’ throughput provides the “rate of information transfer” from the ...
