# A Virtual Coach to Enhance Surgical Training using Human-Centric Modeling and Adaptive Haptic Guidance > **NIH NIH R01** · UNIVERSITY OF TEXAS AT AUSTIN · 2021 · $308,003 ## Abstract PROJECT SUMMARY We aim to reduce surgical robotic errors by developing novel technology to coach experienced practitioners by using real-time data-driven predictive models of operator behavior, task difficulty, and expertise levels during complex surgical training tasks. This technology could increase the effectiveness of simulation-based training, particularly for practicing clinicians, as the predictive models will inform the design of adaptive and personalized feedback for the surgeon. Surgical training typically involves didactic learning, skills labs, and practice on live patients. Safety concerns asso- ciated with training on patients has led to significant developments in simulation-based technology; however, existing simulators may lack the ability promote mastery of skills for practicing providers. Improved training is important for both the provider and the patient. An estimated 100,000 death per year occur due to preventable medical errors. In robotic surgeries, the majority of patient injuries can be attributed to inexperience and lack of technical competence of the attending surgeon. These errors could potentially be avoided through personalized and adaptive coaching. In general, robotic systems can sense and adapt to their environment, even act autonomously to complete a task. However, the majority of surgical robots used today are “teleoperated systems". These systems only perform tasks directly commanded by the human operator, possibly with some scaling or tremor cancellation. There is a missed opportunity to leverage the intelligence of robotic systems to sense and interpret the movements of the surgeon and to enable some form of adaptive feedback for personalized coaching. Our prior work in human-centric modeling could hold the key to the technical challenge of integrating intelligent methods into existing surgical robotic training platforms by better understanding the technical strengths and weaknesses of the practicing surgeon in a data-driven manner. The long-term goal of this project is to improve surgical training outcomes by developing a personalized and adaptive surgical robotic coach capable of providing meaningful feedback to the practicing provider to optimize learning and skill transfer. The specific aims of the proposal include: (1) evaluate the ability of human- centric models to characterize surgeon performance using motion and video data, (2) design adaptive haptic or visual guidance cues to provide learners with real-time feedback and to optimize learning, and (3) evaluate the effectiveness of the adaptive technology coach through end-user validation using procedural-specific training models for general surgery, urology, and gynecologic oncology. This project could significantly improve provider training in robotic surgery. The project could also improve provider training for laparoscopic and open surgery as the models used to develop the virtual coach are inherently human-centric and not tied to any specific surgic... ## Key facts - **NIH application ID:** 10265456 - **Project number:** 5R01EB030125-02 - **Recipient organization:** UNIVERSITY OF TEXAS AT AUSTIN - **Principal Investigator:** Ann Majewicz Fey - **Activity code:** R01 (R01, R21, SBIR, etc.) - **Funding institute:** NIH - **Fiscal year:** 2021 - **Award amount:** $308,003 - **Award type:** 5 - **Project period:** 2020-09-18 → 2024-06-30 ## Primary source NIH RePORTER: https://reporter.nih.gov/project-details/10265456 ## Citation > US National Institutes of Health, RePORTER application 10265456, A Virtual Coach to Enhance Surgical Training using Human-Centric Modeling and Adaptive Haptic Guidance (5R01EB030125-02).
