Additional Titles

Quote: the amount of information needed to perform a targeting task is proportional to log(tolerance/amplitude)

Quote: if amplitude and tolerance are fixed, response time is proportional to the information per response

Quote: when measured in information units, the performance capacity of the human motor system is relatively constant over a considerable range of task conditions; 10-12 bits/sec over much of the range from 1 to 10 bits/response
