Performance of these control interfaces is commonly quantified using offline classification accuracy, despite researchers having shown that this metric is a poor indicator of usability. Several attempts have been made to find alternative training metrics that better correlate with online performance. Moderate correlations have been identified in some cases; however, the relationship between offline training and online usability has yet to be fully defined in the literature. The following work attempts to bridge this information divide by exploring combinations of offline training metrics capable of predicting myoelectric control usability. The results indicate that linear combinations of three offline training metrics provide superior predictive power of future online performance. Additionally, the role of feedback presented to the user during training is explored to determine its effect on performance and predictability. The results of this study suggest that properly designed feedback mechanisms can influence both the quality of the training metrics and the predictive ability of the developed linear models.text/xmlxvi, 116 pageselectronicen-CAhttp://purl.org/coar/access_right/c_abf2master thesis2023-03-01Scheme, ErikEnglehart, KevinElectrical and Computer Engineering
