This is a project I did a number of years ago which I continue to use with my students now. Thank you to all of the volunteers and their altruism


  • 1.Altruistic Avatars: volunteering in the 3D virtual world Evelyn McElhinney aka Kali Pizzaro

2. Discuss the use of 3D virtual worlds for Clinical Simulation Describe the process involved in recruiting, training and working with volunteers in the 3D virtual world Feedback mechanisms for students and volunteers Results from exploratory study of volunteers experience 3. What are 3D virtual worlds? 3D social networking multi user environment (MUVE) Learner control - Users create a digital representation of self (avatar) Immersive - immersed in the environment, subjective feeling of presence and social presence, Sharable user generated digital contents Viewer required or web interface (de Frietas 2008) 4. Users create avatars Digital representation driven by humans (Blascovich and Bailenson 2011). Pictures Andy Whiteford 5. WHY? Learn diagnostic history taking No space in CSL lab Part time students - competing demands on time Difficult to ensure 'protected learning time' in clinical area Already using VW for PBL scenario 6. Solution Practise in class when able - scripted patient nurse (student) - student (simulating patient) Remote practise in 3D virtual world lab with scripted patient - nurse (student) - student (simulating patient) Remote practise via automated bot - Remote practise with remote 7. An exploratory study to determine volunteers experience of engaging in sharing their real life health history with nurses in a virtual world 8 Volunteers 4 in the pilot Age range 32 74 All male 8. Ethical challenges To pay or not to pay, that is the question? Are they volunteering? Keeping safe in the 3D virtual world 9. Recruitment 10. Practical challenges Must have access to computers that can run the virtual world to teach volunteers You must know how to use the 3D VW Create simple guide or video Volunteers must have home access to a newish computer and broadband (so must you)! Provide headsets for voice 11. Take volunteer history remove diagnostic indicators Ensure student/volunteer available Provide support via private instant Message Feedback from volunteer to student via voice Feedback to you refine scenario Setting up the scenario 12. Student feedback Did this session feel any more authentic than your previous scripted session which was played by an actor ? If so why? Student 1: It was good to speak to a patient with real symptoms and able to take a real history. There were no scripted answers. Also he had a number of problems which is good as patients in hospitals can be complex Student 2: I can see where this could be an issue for others, but having experienced both a facilitator and a practice patient I find no difference in authenticity. When Im taking a history in second life, it is easy for me to immerse myself in the experience 13. Virtual Patient Feedback Anonymity I think generally, unless you are seeing the student face to face, that this kind of technique works better anonymously 14. Immersion/Presence Important area was authentic, however all would have preferred consulting room as opposed to ward area It added to the realism of the situation It could be adapted to a Health Visitors room or a GPs surgery depending on the student cohort 15. Avatar identity Embodiment Volunteer - All commented that they did not change their avatar. However, noted that they did not look like default avatars Nurse no requirement for nurse to be in uniform, could not remember what the nurse was wearing 16. Feelings about sharing history Enjoyed being involved, no problem sharing health history Happy to help, no qualms at all. No different to going to a new nurse 17. Communication Via text or Voice Preference for text due to SL voice problems and deafness 18. Support Important that Module Leader available to trouble shoot any student or volunteer issues To facilitate any queries with use of SL or dialogue with student. Important to reflect what happens in real lab 19. Time to get comfy with 3D VW Average = 4 hours Volunteers practise on their own and together by distance with or without module leader 20. What happened next Recruited more volunteers including international from within the VW Increased diversity of disorders Volunteers for inter-professional scenarios and collaboration with international colleagues Students are given feedback at the end of the session include feedback after reflection 21.
