Since the LMC is marker-less, portable, easy-to-use and low-cost, it is rapidly being adopted in healthcare services. This paper demonstrates the comparison of finger kinematic data between the LMC and a gold-standard marker-based motion capture system, Qualisys Track Manager (QTM). Both systems were time synchronised, and the participants performed abduction\/adduction of the thumb and flexion\/extension movements of all fingers. The LMC and QTM were compared in both static measuring finger segment lengths and dynamic flexion movements of all fingers. A Bland\u2013Altman plot was used to demonstrate the performance of the LMC versus QTM with Pearson\u2019s correlation (r) to demonstrate trends in the data. Only the proximal interphalangeal joint (PIP) joint of the middle and ring finger during flexion\/extension demonstrated acceptable agreement (r = 0.9062; r = 0.8978), but with a high mean bias. In conclusion, the study shows that currently, the LMC is not suitable to replace gold-standard motion capture systems in clinical settings. Further studies should be conducted to validate the performance of the LMC as it is updated and upgraded.<\/jats:p>","DOI":"10.3390\/s21051750","type":"journal-article","created":{"date-parts":[[2021,3,3]],"date-time":"2021-03-03T20:33:57Z","timestamp":1614803637000},"page":"1750","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Comparison of the Performance of the Leap Motion ControllerTM with a Standard Marker-Based Motion Capture System"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4093-1101","authenticated-orcid":false,"given":"Amartya","family":"Ganguly","sequence":"first","affiliation":[{"name":"Optimization, Robotics and Biomechanics, Institute of Computer Engineering, Heidelberg University, 69120 Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"Rashidi","sequence":"additional","affiliation":[{"name":"Optimization, Robotics and Biomechanics, Institute of Computer Engineering, Heidelberg University, 69120 Heidelberg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1353-0943","authenticated-orcid":false,"given":"Katja","family":"Mombaur","sequence":"additional","affiliation":[{"name":"Canada Excellence Chair in Human-Centred Robotics and Machine Intelligence, University of Waterloo, Waterloo, ON N2L 3G1, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Cheng, L.L., and Liu, H.B.
