Investigating generalization of low-risk ergonomic positioning across tasks after AI-generated video feedback

Principal Investigator: Dr. Nicole Gravina, Department of Psychology at the University of Florida

Work-related musculoskeletal disorders (WRMSDs) affect millions of Americans. Prolonged risky ergonomic positioning is a significant factor in the development of WRMSDs, and systematically decreasing this risk is of critical importance. Previously, AI-generated video feedback has been demonstrated to increase low-risk neck positioning during an analog work task. This study seeks to extend this research by examining generalization across analog work tasks: can we train safe ergonomic positioning in one context and expect those effects to generalize to other contexts, or do we need to provide video feedback for each context to promote safe posture?

The use of Artificial Intelligence (AI) in ergonomic measurement and intervention is a recent development in occupational safety. This research will further our understanding of the potential and limitations of AI in ergonomics.

I joined the Ergonomics in the Workplace project in January 2023. Since then, I have facilitated participant sessions, collected ergonomic data using AI software, collected informed consent, completed exit interviews, analyzed data, and presented findings at the Florida Undergraduate Research Conference and UF Psychology Graduate Student Organization Undergraduate Research Forum. Within this line of research, I have assisted in studies related to the efficacy of AI-generated video feedback in improving neck positioning, as well as the maintenance of improved posture over time.
