Medical Applications of VR Suzanne Weghorst Human Interface Technology Lab University of Washington human interface technology lab
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
Virtual Retinal Display • high resolution • bright enough for see-through display • small “exit pupil” produces long depth of focus human interface technology lab
Optical Tools for Medicine • True 3D display (Furness/Seibel) • scanned fiber endoscope (Seibel) • optical tomography (Seibel) human interface technology lab
Medical Informatics • virtual ER • distributed tumor board • virtual anatomy browser (Campbell) human interface technology lab
Therapeutic Uses of VR • pain distraction • phobia desensitization • perceptual prosthesis (e.g. Parkinson’s Disease) Meredith Bricken, 1990 human interface technology lab
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
Virtual Vision Sport human interface technology lab
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
Why Surgical Simulation? • training • credentialing • planning and rehearsal • telesurgery/OR of the future human interface technology lab
See One, Do One, Teach one human interface technology lab
Once is Not Enough human interface technology lab
Big Questions • What is the objective of the simulation? • What do you need to simulate to achieve the objective? human interface technology lab
Core Design Issues • anatomical detail • graphical realism • haptic realism • instrumental realism • bells and whistles • user (proctor) interface • validation human interface technology lab
