The weight of a loaded belt can range from ~25–35 lbs. Such loading can lead to overexertion and associated injuries (e.g., low back pain) as well as reduced officer performance leading to injuries from violence. In addition, the distribution of the load can compromise officer balance, leading to slips and falls. The objective of this research was to identify design issues with current duty belts and to develop a design framework for police department use in creating custom ergonomic configurations of equipment on a belt. The study was divided into three phases: a literature review, a field study, and design of the ergonomic belt configuration. The resulting design framework for duty belt equipment configuration may serve as a design guideline for police departments and may reduce the incidence of officer musculoskeletal injuries.}, journal={ADVANCES IN PHYSICAL ERGONOMICS & HUMAN FACTORS}, author={White, Melissa Mae and Kaber, David B. and Deng, Yulin and Xu, Xu}, year={2019}, pages={3–15} }

Physical characteristics of upper-extremity exoskeletal orthotics, used in stroke rehabilitation, were evaluated in terms of performance of activities of daily living (ADL), perceived exertion, and muscle load. Simulated orthotic weight distributions, with total extremity loads of 0.81 kg, 1.25 kg and 2.27 kg, were evaluated along with a 0 kg control condition. Response measures included average shoulder/elbow muscle surface electromyography (sEMG) signal amplitude, quality of task completion and total rest time during performance, and Borg CR-10 scale ratings. Device weight distribution, or imposed shoulder moment, was found to have a significant effect on biceps brachii and anterior deltoid activation levels, percent task completion, total rest time, and perceived exertion ratings. Results suggest that heavier upper-extremity orthotics could cause undesirable effects in terms of muscle loading, performance and exertion; such adverse effects could potentially lead to lack of use during patient’s rehabilitation.}, journal={APPLIED ERGONOMICS}, author={White, Melissa M. and Morejon, Olivia N. and Liu, Shijing and Lau, Mei Y. and Nam, Chang S. and Kaber, David B.}, year={2017}, month={Jan}, pages={190–197} }

Three types of response measures were captured to assess the control schemes, including learnability, performance, and cognitive workload. Prior research has applied performance and cognitive workload metrics for evaluation of prosthetics; however, workload measures applied in these studies (e.g., heart rate, electroencephalography, and respiration rate) have many limitations. This study used eye tracking to compare cognitive load implications of the different control schemes for a two degrees-of-freedom myoelectric prosthesis. In total, 12 participants were assigned to either control condition (six persons each) or perform a clothespin relocation task. Results revealed the PR scheme to be more intuitive for users and superior to DC across all response measures. We observed a lower learning percentage (i.e., greater learning potential), lower cognitive load, and greater productivity in task performance. This preliminary study illustrates efficacy of using eye-tracking-based measures of cognitive load and standardize test paradigms for assessment of upper limb prosthetic usability and supports PR prosthetic device control as an intuitive alternative to DC.}, number={6}, journal={IEEE TRANSACTIONS ON HUMAN-MACHINE SYSTEMS}, author={White, Melissa Mae and Zhang, Wenjuan and Winslow, Anna T. and Zahabi, Maryam and Zhang, Fan and Huang, He and Kaber, David B.}, year={2017}, month={Dec}, pages={1146–1157} }

Different from existing clinical evaluations involving dual-task performance, pupillography measured with an eye-tracking system was used to quantitatively assess user cognitive workload in using a 2 degree-of-freedom prosthesis for a clothespin task. Test results revealed the PR control to produce superior task performance and to require lower cognitive load than demanded of participants under the DC condition. This study provided evidence of both performance and workload advantages of PR control over DC control. PR control was more intuitive to the prosthesis user and, therefore, required less cognitive effort. Furthermore, the study identified a new effective measure of cognitive workload in upper limb prosthesis use via pupillography.}, booktitle={Ieee international conference on systems man and cybernetics conference}, author={Zhang, W.
