Fitts' throughput and the speed-accuracy tradeoff

  title={Fitts' throughput and the speed-accuracy tradeoff},
  author={I. Scott MacKenzie and Poika Isokoski},
We describe an experiment to test the hypothesis that Fitts' throughput is independent of the speed-accuracy tradeoff. Eighteen participants used a mouse in performing a total of 5,400 target selection trials. Comparing nominal, speed-emphasis, and accuracy-emphasis conditions, significant main effects were found on movement time (ms) and error rate (%), but not on throughput (bits/s). In the latter case, failure to reject the null hypothesis of "no significant difference" (i.e., .05 < p < 1… CONTINUE READING
