  2. 2. Summary <ul><li>This presentation will focus on: </li></ul><ul><li>VR in Health Care : </li></ul><ul><ul><li>Research showed its potential in behavioral health and rehabilitation </li></ul></ul><ul><ul><li>But its real impact is minimal. Why? </li></ul></ul><ul><li>PC based VR </li></ul><ul><ul><li>VR Hardware is now very cheap: about 3000 US$/2400 € </li></ul></ul><ul><ul><li>But the software is a problem: expensive, and difficult to develop and customize </li></ul></ul><ul><li>The NeuroVR Project </li></ul><ul><ul><li>A virtual reality platform based on open-source software </li></ul></ul><ul><ul><li>NeuroVR Editor to customize 12 pre-developed scenes </li></ul></ul><ul><ul><li>NeuroVR Player for immersive 3D visualization </li></ul></ul><ul><li>Future perspectives </li></ul><ul><ul><li>3d animation and support for PDAs </li></ul></ul><ul><ul><li>Possible collaboration with us </li></ul></ul>
  3. 3. Is VR a promise or a reality for clinicians and rehabilitators?
  4. 4. Virtual Reality Technology <ul><li>VR is usually described as a collection of technological devices : </li></ul><ul><ul><li>a computer capable of interactive 3D visualization, </li></ul></ul><ul><ul><li>a head-mounted display and data gloves , </li></ul></ul><ul><ul><li>equipped with one or more position trackers . </li></ul></ul><ul><li>The trackers sense the position and orientation of the user and report that information to the computer that updates (in real time) the images for display. </li></ul>
  5. 5. Reality: VR in Health Care <ul><li>1989: First VR company (VPL Research) founded </li></ul><ul><li>1991: Virtuality Game System </li></ul><ul><li>1993: Suggested the use of VR in psychological treatment </li></ul><ul><li>1993: Suggested the use of VR in surgical simulation </li></ul><ul><li>1995: First research papers on VR in neuro-psychological assessment and treatment </li></ul><ul><li>1997: First research paper on VR in eating disorders </li></ul><ul><li>2007: more than 1600 papers in MedLine and 1300 in PsycInfo </li></ul>
  6. 6. Promise: VR in behavioral health <ul><li>Research papers show that VR has come of age for clinical and research applications : </li></ul><ul><li>exposure therapy : the patient is gradually confronted with the virtual simulation of feared stimuli while allowing the anxiety to attenuate </li></ul><ul><li>pain distraction : VR reduces acute pain </li></ul><ul><li>body image modification : VR modifies the bodily experience: it may be used in eating disorders </li></ul><ul><li>neuropsychological testing and rehabilitation : </li></ul><ul><li>VR allows to deliver interactive 3D stimuli in a variety of forms and sensory modalities cognitive neuroscience : researchers carry out experiments in an ecologically valid situation, while still maintaining control over all variables </li></ul>
  7. 7. Reality: VR is a research toy <ul><li>VR has the potential for being a poweful tool for behavioral health </li></ul><ul><li>But its real impact in behavioral health is still low: </li></ul><ul><ul><li>The penetration of VR in behavioral health care/research centers is minimal: around 0.5/1% </li></ul></ul><ul><ul><li>The penetration of VR between behavioral health professionals is even lower: less than 0.001% </li></ul></ul><ul><ul><li>WHY? </li></ul></ul><ul><ul><li>Is VR too expensive/difficult to use? </li></ul></ul>
  8. 8. Immersive Tools $2,900 $10,000 $60,000 $500-2,000 $900 $24,000 $1,800 Head Mounted Displays “ Near Eye Immersive Display Systems”
  9. 9. Tracking Tools $1,800 $5,000 $900 $5,000 -15,000
  10. 10. <ul><li>For many years one of the main obstacles to the use of VR was the price of the equipment : a typical VR system in the early ’90s required a costly Silicon Graphic workstation in the range of 250000 US$. </li></ul><ul><li>The significant advances in PC hardware are transforming PC-based VR into a reality . </li></ul><ul><li>A simple immersive VR system now may cost less than 2000 €; a professional one 3000/30000 € </li></ul>VR Hardware: No more problems
  11. 11. <ul><li>Head Mounted Display with tracker Z800 3D Visor : 900 $ </li></ul><ul><li>Intel Core 2 Duo PC with Nvidia GeForce 8800 GTX graphic card: 1900 $ </li></ul><ul><li>Wireless joystick and/or P5 Glove : 100 $ </li></ul><ul><li>Wiimote from Nintendo : 80$ </li></ul>Immersive 3D Hardware: less than 3000 US$
  12. 12. <ul><li>There is a limited number of ready to use solutions for behavioral health </li></ul><ul><li>Their price is higher than the hardware one (5000-15000 US$) </li></ul><ul><li>Limited customization possibilities </li></ul><ul><li>Developing a new VE is expensive and time consuming </li></ul><ul><li>Exchange of VEs is problematic (royalties, copyrights, runtimes) </li></ul>The real problem: software
  13. 13. <ul><li>Easy to use : A rich, interactive, user-friendly interface </li></ul><ul><li>Many different sources : Innovation in assembly of system and sites composed by pulling together features from distributed, independent developers (a kind of &quot;open source&quot; development). </li></ul><ul><li>Network effect : created by an architecture of participation that encourages users to add value to the application as they use it. [ </li></ul>A success story: Web 2.0
  14. 14. Towards VR 2.0: the NeuroVR project
  15. 15.
