The objective of this project is to evaluate the muscle activity and joint net torque in hand, shoulder, and low back during patient transfer using four different engineering controls: a conventional cotton draw sheet, friction-reducing slide sheet, friction-reducing slide board, and air-assisted transfer device. Expected outcome is to determine the most effective patient handling device improving the safety and health of caregivers and patients.
Product Design and Evaluation
The objective is to evaluate the effect of the wearable posture correction sensor on the changes of the behavior of office workers to set up the preferred workstation, and associated biomechanical exposures of the neck while sitting and standing.
The goal of this study is to evaluate the usability and biomechanical stress of the whole body while using the French door refrigerator handle of three doors and four doors models. The expected outcomes are:
- The typical behavior of users to interact with different types of handles (recessed, bar, and showcase)
- Optimal height of the recessed handle and
- Optimal type of the recessed handle (bar, recessed handle with different clearances).

The goal of this study is to provide an ergonomic recommendation by comparing joint angles and subjective comfort measures for guitarists using footstools and/or guitar supports.
Developing Ergonomic Guidelines
The goal of this study is to evaluate the effect of the armrest and backrest support on the head and neck kinematics, gravitational moment, muscle activities, and perceived discomfort on the neck. The expected outcome is to determine the optimal chair condition promoting the neutral postures of the neck while using the smartphone.

The objective of this project is to characterize the biomechanical stresses in the neck and the shoulder, subjective comfort, and usability during AR interactions. We will evaluate reach envelopes and preferred hand gesture patterns in 27 different areas (3 X 3 X 3 cube) during AR interactions. This study will advance the current knowledge on AR interactions and their associated biomechanical exposures.
The objective of this study is to determine the most comfortable and effective vertical location of the virtual scene by assessing the 3D joint angles and muscle activity of the neck and shoulder, subjective discomfort, motion sickness, and task performance.
