Ergonomics of Total Knee Arthroplasty
… demands. Robotic platforms may alter this load, but their ergonomic impact is unclear. We compared biomechanical strain and workload during conventional versus robotic-assisted TKA. Methods Two surgeons and two scrub nurses each performed conventional and robotic TKA (three cases per …

An Investigation into Locomotion Techniques for Use in Virtual Reality Games
… Usability Scale Questionnaires, and overall workload measured from the NASA Task-Load Index Questionnaire. We also found that RSRT and World Grab were least preferred overall and performed measurably worse in terms of time, number of falls in a section designed to measure precision and accuracy, …

The Effect of Crosswind and Turbulence in Mental Workload and Pilot Tracking Performance
… effect of crosswind and turbulence on mental workload and pilot tracking performance. Based on previous research, it was believed that as the amount of crosswind and turbulence is increased, mental workload would increase and tracking performance would decrease. The objective was to estimate the …

Performance study of flight deck interface systems for air traffic control-pilot data link communications (CPDLC)
… that there was little difference in performance (task processing time, accuracy and efficiency) among the four interface configurations in simple communication tasks. However, as the level of difficulty of these tasks increases, a dual interface configuration with separate functionality on each …

The Effects of Mindfulness on Anxiety and Cognitive Load in Prelicensure Nursing Learners During Simulation-Based Learning
… induces anxiety, which can increase cognitive load and hinder learning. Evidence suggests mindfulness-based activities (MBAs) reduce anxiety and cognitive load, potentially improving memory retention and knowledge application. This study explores the effect of MBAs on anxiety and cognitive load …
