Threshold of classification. The figures represent, left to right, the intraclass speed classification for the mean (f 1) and the interclass speed classification for the SD (f 2) of the hand instantaneous velocity. The intraclass figure was made by superimposing the figure from each subject and computing thresholds using the average values of each subject threshold. The two dashed lines point to the two valleys in the figure, and their x-axis values are the used thresholds.
