This study examined the right to left symmetry of the displacement of three-dimensional movement of the human face.
Displacement data on 42 subjects was collected and analyzed with the Expert Vision Motion Analysis System. Right and left three-dimensional facial displacements were quantified.
Significantly greater left than right three-dimensional displacement across the whole face was measured. The three-dimensional displacement difference ranged from 0.48 mm to 2.28 mm between the right and left sides of the face. The 2-cm inferior pupil markers during the nose wrinkle expression had significantly greater left than right displacement.
The ranges of displacement differences, along with the mean three-dimensional displacement measures, must be accounted for in the creation of a baseline of the range of normal facial movement.
本研究检测了人类面部三维运动位移的左右对称性。
收集42名受试者的位移数据，并使用专家视觉运动分析系统进行分析。对左右面部的三维位移进行量化。
测量发现，整个面部的三维位移显著左大于右。面部左右两侧的三维位移差异在0.48毫米至2.28毫米之间。在皱鼻表情期间，瞳孔下方2厘米处的标记点位移显著左大于右。
在建立正常面部运动范围的基线时，必须考虑位移差异范围以及平均三维位移测量值。
