  1. Medical Applications of VR Suzanne Weghorst Human Interface Technology Lab University of Washington human interface technology lab

  2. HIT Lab Medical Projects • broad spectrum of medical applications • tools for clinical practice • medical informatics • therapeutic VR/AR • surgical simulation • www.hitl.washington.edu • Medicine Meets VR(www.amainc.com) human interface technology lab

  3. Virtual Retinal Display • high resolution • bright enough for see-through display • small “exit pupil” produces long depth of focus human interface technology lab

  4. Optical Tools for Medicine • True 3D display (Furness/Seibel) • scanned fiber endoscope (Seibel) • optical tomography (Seibel) human interface technology lab

  5. human interface technology lab

  6. Medical Informatics • virtual ER • distributed tumor board • virtual anatomy browser (Campbell) human interface technology lab

  7. Therapeutic Uses of VR • pain distraction • phobia desensitization • perceptual prosthesis (e.g. Parkinson’s Disease) Meredith Bricken, 1990 human interface technology lab

  8. Parkinson’s Disease Kinesia Paradoxa • objects/lines in the subject’s path • transverse lines spaced about one stride-length apart work best • learning/imagining cues doesn’t work human interface technology lab

  9. Virtual Vision Sport human interface technology lab

  10. human interface technology lab

  11. Surgical Simulation • suturing simulation using FFE (fast finite element) methods • ESS (endoscopic sinus surgery) simulator • TURP (trans-urethral resection of the prostate) simulator human interface technology lab

  12. Why Surgical Simulation? • training • credentialing • planning and rehearsal • telesurgery/OR of the future human interface technology lab

  13. See One, Do One, Teach one human interface technology lab

  14. Once is Not Enough human interface technology lab

  15. Big Questions • What is the objective of the simulation? • What do you need to simulate to achieve the objective? human interface technology lab

  16. Core Design Issues • anatomical detail • graphical realism • haptic realism • instrumental realism • bells and whistles • user (proctor) interface • validation human interface technology lab

  17. Anatomical Detail human interface technology lab

  18. in-vivo in-vitro Type 1 Type 2 Type 3 Graphical Realism human interface technology lab

  19. Haptic Realism human interface technology lab

  20. Instrumental Realism human interface technology lab

  21. Bells and Whistles • OR sounds • speech input • intelligent agents • training aids human interface technology lab

  22. System Integration human interface technology lab

  23. Proctor Interface human interface technology lab

  24. Simulator Validation human interface technology lab

  25. Non-MD Junior Resident Senior Resident Staff ENT Simulator Validation human interface technology lab

  26. Collaborators • HIT Lab • Peter Oppenheimer • Jeff Berkley • Chris Airola • Duff Hendrickson • Tim Kowalewsky • UW School of Medicine • Rob Sweet, Jim Porter (Urology) • Dan Berg, Greg Raugi (Dermatological Surgery) • Mika Sinanan (Surgery/CVES) • Others • Chuck Edmond (Madigan Army Hospital - ENT) • Marvin Fried (Montefiore Hospital - ENT) • Rick Satava (Yale Medical School - Surgery) • George Turkiyyah (Civil Engineering) • Mark Ganter (Mechanical Engineering) human interface technology lab
