This　paper　presents　a　new　technique　for　retargeting　the　sign　language　data　captured　from　motion　capture　device　to　different　characters　with　different　sizes　and　proportions.　Realistic　and　natural　animations　can　be　produced　to　express　similar　meanings　to　the　original.　The　proposed　method　first　defines　many　sensitive　points　on　the　human　body　and　selects　the　key　sensitive　points　through　analyzing　the　importance　of　the　sensitive　points.　Next　a　novel　mapping　method　based　on　relative　position　is　presented　to　adapt　the　original　sensitive　points　to　the　target　sensitive　points.　Finally　we　utilize　an　IK　solver　to　realize　the　retargeting　problem.　Experimental　results　show　that　the　proposed　method　dramatically　improves　the　recognition　rate　about　30%.　Copyright　UNION　Agency　-　Science　Press.
