Graphical summary of myocontrol performance metrics. Metrics of motion-normalized proportional linear discriminant analysis (LDA) and the proposed myoelectric representation learning (MRL) method were obtained from evaluations conducted immediately following calibration (day 1) and after one week of intermission (day 7). Performances achieved by test subjects using the gold standard (GS), i.e. a computer mouse, are included for reference. Markers and error bars represent arithmetic means and standard deviations, respectively, across all 20 test subjects
