Research Achievements in Construction Ergonomics
As the rapid development and extensive applications of motion capture technology in the past few years, advances in WMSD assessment have been made in the construction research field, especially on the posture-oriented assessment. Among them, vision-based studies and wearable sensor systems are two main ongoing streams and the details are discussed respectively. Table 4 provides a state-of-the-art overview in achievements of a variety of works in construction in terms of sensors, focused risks, and data processing.

Vision-Based Methods
The vision-based method is a marker-less assessment method. It relies on depth sensors or multiple cameras to achievement 3D reconstruction of objects. Computer vision methods are applied for skeleton extraction and motion tracking. In terms of the evaluation of the performance of vision-based methods, the accuracy of the captured motion data (e.g., rotation angles, joint angles, position vector, and movement direction) is fundamental in the body part tracking and post motion analysis.
 Kinect
As an emerging vision-based human kinematics assessment tool, Microsoft Kinect has been applied in capturing 3D information of the human body since it was first introduced in 2010 (Ning and Guo 2013; Goetsch and Goetsch 2003; Ray and Teizer 2012; Han et al. 2013). Significant research efforts have been invested in action machine learning and unsafe action detection (Han et al. 2012;…
