Abstract
An experimental study shows that the classical Fitts' law of motor control, which is claimed to be based on an inappropriate analogy with information theory, yields false estimates for the information capacity of the human motor system. An alternative and rigorous estimation method indicates that the maximum information capacity is about 22–24 bits/sec. for discrete single one-dimensional positioning movements.This publication has 3 references indexed in Scilit:
