The initial processing of the input data was oriented towards extracting relevant time domain features of the EMG signal. Following the feature calculation, a piecewise modeling of the multidimensional EMG feature dynamics using vector autoregressive models was performed. The next step included the implementation of hierarchical hidden semi\u2010Markov models to capture transitions between piecewise segments of movements and between different movements. Lastly, inversion of the model using an approximate Bayesian inference scheme served as the classifier. The effectiveness of the novel algorithms was assessed versus methods commonly used for real\u2010time classification of EMGs in a prosthesis control application. The obtained results show that using hidden semi\u2010Markov models as the top layer, instead of the hidden Markov models, ranks top in all the relevant metrics among the tested combinations. The choice of the presented methodology for the control of prosthetic hand is also supported by the equal or lower computational complexity required, compared to other algorithms, which enables the implementation on low\u2010power microcontrollers, and the ability to adapt to user preferences of executing individual movements during activities of daily living.<\/jats:p>","DOI":"10.1155\/2018\/9728264","type":"journal-article","created":{"date-parts":[[2018,2,18]],"date-time":"2018-02-18T23:32:07Z","timestamp":1518996727000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Vector Autoregressive Hierarchical Hidden Markov Models for Extracting Finger Movements Using Multichannel Surface EMG Signals"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4821-7666","authenticated-orcid":false,"given":"Neboj\u0161a","family":"Male\u0161evi\u0107","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dimitrije","family":"Markovi\u0107","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gunter","family":"Kanitz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Controzzi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Cipriani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Antfolk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,2,18]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1615\/critrevbiomedeng.v30.i456.80"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/MSP.2012.2203480"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2012.2196711"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1108\/01439910810876364"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1186\/1743-0003-7-42"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2016.2578980"},{"key":"e_1_2_8_7_2","unstructured":"Touchbionics http:\/\/www.touchbionics.com\/."},{"key":"e_1_2_8_8_2","unstructured":"bebionic http:\/\/bebionic.com\/."},{"key":"e_1_2_8_9_2","unstructured":"Michelangelo http:\/\/www.ottobockus.com\/prosthetics\/upper-limb-prosthetics\/solution-overview\/michelangelo-prosthetic-hand\/."},{"key":"e_1_2_8_10_2","unstructured":"Vincent hand http:\/\/vincentsystems.de\/en\/."},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1186\/1475-925X-11-33"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2011.2178039"},{"key":"e_1_2_8_13_2","first-page":"71","article-title":"A novel feature extraction for robust EMG pattern recognition","volume":"1","author":"Phinyomark A.","year":"2009","journal-title":"Journal of Computing"},{"key":"e_1_2_8_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bspc.2007.07.009"},{"key":"e_1_2_8_15_2","doi-asserted-by":"publisher","DOI":"10.1126\/scitranslmed.3008933"},{"key":"e_1_2_8_16_2","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2014.2323576"},{"key":"e_1_2_8_17_2","doi-asserted-by":"publisher","DOI":"10.1080\/03091900512331332546"},{"key":"e_1_2_8_18_2","doi-asserted-by":"crossref","unstructured":"BitzerS.andVan Der SmagtP.
