I wrote a program that measured repetition rate while alternating key presses between 2 fingers. It would also measure the time it took to press a randomly displayed letter. There was some success in measuring the response times however in analyzing the data it was not sensitive or repeatable enough for fine tuning medication. After reading Janet's post on digitography I think I will revisit my program and data. Dan Parker wrote: > Has somebody written a program to use your PC to measure digitography?
