Virtual Environment Fidelity Flatworlds, USC, ICT
5
Goal of Talk Virtual environments have high fidelity Flatworlds, USC, ICT Virtual Iraq, USC, ICT Ford Vehicle Simulator
6
Goal of Talk I propose the next area of VR and computer graphics research will focus on virtual humans How virtual humans affect people How people are using virtual humans Research directions of virtual humans Motivate you to explore virtual humans in your own research Image courtesy of Skip Rizzo, University of Southern California

Example Virtual Human Interaction Video courtesy of Skip Rizzo, University of Southern California
8
Can interacting with a virtual human make you a better person? Dr. Gregory House Good with medical knowledge Not so good with interacting with people Dr. Doug Ross Good with medical knowledge Good with interacting with people Dr. Derek Shepherd Good with medical knowledge Good with interacting with people
9
Expanding applicability of simulation Humans are social creatures Virtual humans impact us in a fundamentally differently way than virtual environments Virtual humans enable computer graphics and virtual reality to be applied to new areas
10
This talk will focus on Virtual humans as interaction partners How can they affect us? Teach us? Change us?
11
Deployment - Continuum of Experiences Virtual Worlds Immersive Interaction Video Conference Chat Web Browser Instant Message Mobile Deployment Immersion Images from www.virtualpatientsgroup.com Fidelity, Learning efficacy

Pixels mean different things What do you see?
21
Training Think of tasks that everyone does almost everyday… Interact with another person Yet training for this is very limited. Humans are social creatures!
22
How do people train to interact with others? Lectures Human resources training Case studies Videos Role-play With other students, instructors, actors Actors -> gold standard for many fields Medicine Military
23
Training with a VH Impacts Education (teachers with students) Military (leadership training) Law Enforcement (police officers and suspects) Justine Cassell – Carnegie Mellon University, USC ICT
24
Real change in behavior
25
Would you be influenced more by? Baylor & Plant 2005
26
Benefits of Virtual Humans? Providing experiences is logistically complex Frequency Standardization Diversity Feedback Resources Military Version Sexual Assault Patient Prototype Image courtesy of Skip Rizzo, University of Southern California
27
Benefits of Virtual Humans? Abnormal findings
28
New research areas Visual realism Haptics Cognition Personality What would it take to make people care VR notions of presence and immersion do not directly apply Image courtesy of Justine Cassell, Carnegie Mellon University
29
Future Implications Revolutionize interpersonal training – Culture – Communication Skills Help people with communication skills deficiencies – Fear of public speaking – Social phobias (e.g. paranoia) – Autism – Bias Images courtesy of Sabarish Babu – Clemson University

31
So Can Virtual Humans Make You a Better Person? If you want them to, we know they can Affect you You can learn from interacting them Change your behavior
32
We can do a better job to Expose others to our new findings and technology How many people have tried out your innovations? There is a hunger out there!
33
Virtual People Factory www.virtualpeoplefactory.com www.virtualpeoplefactory.com Web-based interface to virtual humans Deployed Early 2008 56 active developers 2700 users 105,000 utterances Demo Demo
34
Mobile Distribution of Simulation Deploy simulations via mobile platforms Android app, released December 2010, over 4600 downloads In Android Market, search for “Virtual Patient” Image from www.virtualpatientsgroup.com
35
Museum of Science and Industry Science museum in Tampa, FL Integrate a VH interaction Public health literacy Research About 4000 people per year enter our exhibit About n=~400 per year are usable datapoints for studies
36
Repositories MedEdPORTAL Peer reviewed medical education resource 400 institutions downloads in 10 months
37
Play Video Games Wii mote, Kinect, 3D Displays, Large displays, smartphones People are leveraging VR technologies They would benefit from our research We must be willing to adapt
38
Social Network, Read Engadget Embrace these communities Or risk obsolescence Our students already are, our collaborators are beginning to Leverage social networks distributions E.g. Johnny Lee wiimote (15 million views) How many google citations are a “seminal paper” Rendering equation – google scholar 1480. Justin Bieber – 630 million views
39
I hope this talk motivated you to… Explore virtual humans in your research As a community, have more people interact with your research Embrace the new wave of technology to interact and distribute Inspire people outside this room
