The time needed to reach a target of width located at distance varies as a logarithmic or power function of the quotient of /. The received, strong version of Fitts' law requires isochrony-the invariance of across different / conditions with the same quotient-but there is room for a weaker, yet nontrivial version of Fitts' law where s...More
