  3. Consortium Overview • Started in Spring 2004 • Four universities • 32-person team including • Computer Science • Medicine • Education • Psychology • 53 active members

  4. Consortium Overview • Experiences • Immersive: 567 • Online: 1000+ • Public exhibits and demos: 100s • 24 scenarios • Publications: 9 journal, 16 conference, 18 abstracts • Awards: • IEEE VR 2008 Best Paper • Research and Clinical Abstract Awards (Georgia ACS) • $2.8 million in funding (NSF, NIH, and ASE)

  5. Publicity • www.virtualpatientsgroup.com • www.virtualpeoplefactory.com • Virtual Patients Webpage

  6. Experiences with Virtual Patients • Students practice communication + diagnostic skills • Scenarios can be: • Repeatable • Standardized • Feedback • Longitudinal learning • Abnormal findings • Diverse virtual patients • Tailored for each student

  7. Scripts (24) http://vpf.cise.ufl.edu/wiki/index.php/VPF_Script_Tracking • Anesthesia • Pre-op OSA (UF) • Conscious sedation (UF) • Cancer • Abnormal mammogram (UF) • BRCA Pedigree (UCF) • Clinical breast exam (UF/MCG) • Melanoma (MCG) • Pain • Abdominal Pain (UF) • Chest pain (UF) • Gallstones (UCF) • Lower back pain (UF) • Lower back pain (PCOM) • Psychiatry • Failure to thrive (UF) • Depression (MCG) • Bi-polar (MCG) • General • Breaking bad news (MCG) • Cranial Nerve (UF) • Dyspepsia – Pharmacy (UF) • Gastro-Band (UF) • GI Hemorrhage (UF) • Meningitis (PCOM) • Patient-Centered Counseling (USF) • Post Operative Hemorrhage (UF) • Sexually Transmitted Diseases (UF) • Contraceptive Counseling (UF)

  8. Continuum of Experiences Web Browser Instant Message Video Conference Chat Second Life Immersive Interaction

  9. Developing Virtual Character Cognition • Virtual People Factory • Web-based interface • End-user creation of content • Pharmacy patient • In one year • Over 2000 interactions • 24 end-user created scenarios • End-user created scripts can reach 85% accuracy

  10. NERVE: The Neurological Examination Rehearsal Virtual Environment • Virtual multi-tool interface to VH • Single input device (Wii Remote) controls multiple virtual tools used in eye exam • Gestural and tool input, in addition to speech • Medical students can • Learn how to use neurological tests to diagnose a patient with a vision disorder • Receive additional exposure to patients with abnormal findings (e.g. double vision, lazy eye)

  11. Physical Examinations of Virtual Human Patients • Mixed reality humans • Passive-haptic interface to life-sized virtual human • Applications • Clinical breast exam • Prostate exam (upcoming) • Medical students can • Practice merging physical examination and communication skill sets • Get real-time feedback of exam performance • E.g. coverage, pressure

  12. Developing a learning experience • Short term • Faculty member leads medical students to use Virtual People Factory • Test with students • Publish and demo • Long term • Develop a deployable teaching unit • Integrate into curricula at UF • Federal funding (e.g. NIH, NSF)

  13. After-Action Review by Students • IPSViz • Web-based interface • Students received email with link (automated) • Sample student (Brent/45169) • Self-directed review of content, video, and feedback • Each student can review their performance and compare with experts

  14. After-Action Review by Educators • IPSVizn • Web-based interface • Educators can review completed student interactions • Data from study • Filter based on user background • Level of expertise • Gender • Educator-defined metrics • Experts can • Identify trends (mean of class) • Identify outliers

  15. Experiences • 24 Patient-Doc scenarios • Intimate Exams • Abnormal Findings (Neurological Exam) • Conscious Sedation (VP+IPS) • Audiology Testing • After-Action Reviews • You, M.D. • Bias studies: Pain perception

  16. Video Conference with a VP • All VPF scripts can be experienced video-conference style • Interact with 3D VPs using a webcam and typing • Enables study of distributed medicine

  17. Audiologycollaboration with Mark Billinghurst (NZ) • Students administer audiology exams to VP • Exams include: • History • VP visual examination • Hearing screen • Testing speech understanding • Highlights • Procedure and communications skills • VP presenting abnormal conditions

  18. Pain Perception • PI: Mike Robinson • Video vignettes of VPs expressing low or high levels (FACS) of pain • VPs varied in gender, age, and ethnicities • Doctors, nurses, and dentists evaluate perceived levels of pain • Identifies variables and weighting of variables that affect healthcare provider’s pain perception

  19. Sponsors • Current support • Prior Support

  20. Consortium Expertise • University of Florida • Technology development • Scenario development • Abnormal findings • Medical College of Geogia • Intimate Exmas • University of Georgia • Patient-centered experiences • University of Central Florida • Assessment • Curricular integration
