记录姿势和运动对于确定工作场所肌肉骨骼损伤的风险非常重要，但现有的运动捕捉系统不适合现场工作。从Kinect的4个0.10米立方体的3-D相对位置的估计进行了比较，从一个Vicon运动捕捉系统的估计，以确定是否硬件传感组件足够灵敏，可用作便携式3-D运动捕捉系统的工作场所人体工程学评估。在x、y和z方向上的均方根误差（SD）分别为0.0065 m（0.0048 m）、0.0109 m（0.0059 m）、0.0057 m（0.0042 m）（x轴向右，y轴远离传感器，z轴向上）。这些数据是在距离设备1.0-3.0 m的范围内收集的，覆盖水平54.0度和垂直39.1度的视场。还考虑了软件、硬件和受试者准备的要求，以确定Kinect在现场的可用性。(C)2011年爱思唯尔有限公司和人体工程学学会。All rights reserved.
Recording posture and movement is important for determining risk of musculoskeletal injury in the workplace, but existing motion capture systems are not suited for field work. Estimates of the 3-D relative positions of four 0.10 m cubes from the Kinect were compared to estimates from a Vicon motion capture system to determine whether the hardware sensing components were sensitive enough to be used as a portable 3-D motion capture system for workplace ergonomic assessments. The root-mean-squared errors (SD) were 0.0065 m (0.0048 m), 0.0109 m (0.0059 m), 0.0057 m (0.0042 m) in the x, y and z directions (with x axis to the right, y axis away from the sensor and z axis upwards). These data were collected over a range of 1.0-3.0 m from the device covering a field of view of 54.0 degrees horizontally and 39.1 degrees vertically. Requirements for software, hardware and subject preparation were also considered to determine the usability of the Kinect in the field. (C) 2011 Elsevier Ltd and The Ergonomics Society.
