The basic plot for this effort is an optimization-based approach, where we believe that different human performance measures govern different tasks. The underlying problem is characterized by the calculation (or prediction) of the human performance measure in such a way as to accomplish a specified task. In this work, we have not limited the number of degrees of freedom associated with the model. Each task has been defined by a number of human performance measures that are mathematically represented by cost functions that evaluate to a real number. Cost functions are then optimized, i.e., minimized or maximized, subject to a number of constraints, including joint limits. The formulation is demonstrated and validated. We present this computational formulation as a broadly applicable algorithm for predicting postures using one or more human performance measures.<\/jats:p>","DOI":"10.1017\/s0263574708004992","type":"journal-article","created":{"date-parts":[[2008,8,11]],"date-time":"2008-08-11T13:53:53Z","timestamp":1218462833000},"page":"607-620","source":"Crossref","is-referenced-by-count":29,"title":["Optimization-based posture prediction for human upper body"],"prefix":"10.1017","volume":"27","author":[{"given":"Zan","family":"Mi","sequence":"first","affiliation":[]},{"given":"Jingzhou (James)","family":"Yang","sequence":"additional","affiliation":[]},{"given":"Karim","family":"Abdel-Malek","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2009,7,1]]},"reference":[{"key":"S0263574708004992_ref18","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-8352(97)00184-8"},{"key":"S0263574708004992_ref19","first-page":"472","volume-title":"Evaluation of Human Work","author":"Porter","year":"1990"},{"key":"S0263574708004992_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/0169-8141(95)00106-9"},{"key":"S0263574708004992_ref14","doi-asserted-by":"publisher","DOI":"10.1016\/0169-8141(95)00080-1"},{"key":"S0263574708004992_ref8","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(96)00028-0"},{"key":"S0263574708004992_ref13","doi-asserted-by":"publisher","DOI":"10.1016\/0169-8141(94)00088-K"},{"key":"S0263574708004992_ref7","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1115\/1.4011045","volume":"77","author":"Denavit","year":"1955","journal-title":"J.
