a Test accuracy confusion matrices before recalibration and after recalibration. The confusion matrix “before recalibration” shows some of the most commonly misclassified gestures after the shift in signal distributions has occurred. The “after recalibration” matrix shows that accuracies are increased after the recalibration phase. b Differences between the initial session and the recalibration session. The mean SNR between the initial session and the recalibration session was not found to be statistically significant. The error bars show 95% confidence intervals for the mean. This shows the test accuracies for the initial dataset, before recalibration, and after recalibration for each participant.
