Learning trends over consecutive experimental blocks during the Fitts’ law trials. (A) Throughput: Subjects using linear regression control demonstrated no significant increase in performance over the course of the experiment for any target complexity, though a possible learning trend was present for 3-DOF targets (p = 0.062). In contrast, subjects using parallel dual-site control exhibited learning for 2- and 3-DOF targets (p = 0.036 and p = 0.003, respectively). (B) Path efficiency: Subjects using linear regression control exhibited learning for 3-DOF targets only (p = 0.015), whereas subjects using parallel dual-site control exhibited learning for both 2- and 3-DOF targets (p = 0.044 and p = 0.037, respectively).
