A multifunctional myoelectric prosthesis controlled using pattern classification can be used to restore some of the lost motor abilities. However, learning to control an advanced prosthesis can be a challenging task, but virtual and augmented reality (AR) provide means to create an engaging and motivating training.</jats:p>\n              </jats:sec><jats:sec>\n                <jats:title>Methods</jats:title>\n                <jats:p>In this study, we present a novel training framework that integrates virtual elements within a real scene (AR) while allowing the view from the first-person perspective. The framework was evaluated in 13 able-bodied subjects and a limb-deficient person divided into intervention (IG) and control (CG) groups. The IG received training by performing simulated clothespin task and both groups conducted a pre- and posttest with a real prosthesis. When training with the AR, the subjects received visual feedback on the generated grasping force. The main outcome measure was the number of pins that were successfully transferred within 20 min (task duration), while the number of dropped and broken pins were also registered. The participants were asked to score the difficulty of the real task (posttest), fun-factor and motivation, as well as the utility of the feedback.</jats:p>\n              </jats:sec><jats:sec>\n                <jats:title>Results</jats:title>\n                <jats:p>The performance (median/interquartile range) consistently increased during the training sessions (4/3 to 22/4). While the results were similar for the two groups in the pretest, the performance improved in the posttest only in IG. In addition, the subjects in IG transferred significantly more pins (28/10.5 versus 14.5/11), and dropped (1/2.5 versus 3.5/2) and broke (5/3.8 versus 14.5/9) significantly fewer pins in the posttest compared to CG. The participants in IG assigned (mean ± std) significantly lower scores to the difficulty compared to CG (5.2 ± 1.9 versus 7.1 ± 0.9), and they highly rated the fun factor (8.7 ± 1.3) and usefulness of feedback (8.5 ± 1.7).</jats:p>\n              </jats:sec><jats:sec>\n                <jats:title>Conclusion</jats:title>\n                <jats:p>The results demonstrated that the proposed AR system allows for the transfer of skills from the simulated to the real task while providing a positive user experience. The present study demonstrates the effectiveness and flexibility of the proposed AR framework. Importantly, the developed system is open source and available for download and further development.</jats:p>\n              </jats:sec>","lang":"eng"}],"author":[{"full_name":"Boschmann, Alexander","last_name":"Boschmann","first_name":"Alexander"},{"full_name":"Neuhaus, Dorothee","last_name":"Neuhaus","first_name":"Dorothee"},{"full_name":"Vogt, Sarah","last_name":"Vogt","first_name":"Sarah"},{"last_name":"Kaltschmidt","full_name":"Kaltschmidt, Christian","first_name":"Christian"},{"first_name":"Marco","last_name":"Platzner","full_name":"Platzner, Marco"},{"last_name":"Dosen","full_name":"Dosen, Strahinja","first_name":"Strahinja"}],"year":"2021","status":"public","date_created":"2021-02-22T10:43:02Z","citation":{"ama":"Boschmann A, Neuhaus D, Vogt S, Kaltschmidt C, Platzner M, Dosen S.
