(A) Changes as the experimental sessions progressed. For 1-DOF targets, no significant trend was observed in throughput for either control system. For targets requiring use of 2- or 3-DOFs, throughput increased throughout the course of the experiment when subjects used parallel dual-site control (p<0.05) but remained stable throughout the experiment for pattern recognition control. Note changes in y-axis. (B) Comparison during last experimental block. In the last session of the experiment, throughput in 2- and 3-DOF targets was greater for parallel dual-site control than for pattern recognition control. When using parallel dual-site control, throughput was 10% and 26% greater for 2- and 3-DOF targets, respectively, than when using pattern recognition control (p<0.05, for 3-DOF targets).
