Figure 4From: An experimental evaluation of the incidence of fitness-function/search-algorithm combinations on the classification performance of myoelectric control systems with iPCA tuningAcquired signal with the sequence of movements from 1 to 11. Signals illustrated correspond to channel 3 during trials 6 to 8 and user 1. Dotted lines indicate the held time for the contraction (4 s). Note that the movements were evaluated in sequential ascending order for all trials.Back to article page
