CAN INTERACTING WITH A VIRTUAL HUMAN MAKE YOU A BETTER PERSON?
BENJAMIN LOK, PH.D.UNIVERSITY OF FLORIDA
ISVC 2011, September 28th, 2011
Goal of Talk
Virtual environments have high fidelity
Flatworlds, USC, ICT
Virtual Iraq, USC, ICT
Ford Vehicle Simulator
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

Can interacting with a virtual human make you a better person?
Dr. Gregory HouseGood with medical knowledgeNot so good with interacting with people
Dr. Doug RossGood with medical knowledgeGood with interacting with people
Dr. Derek ShepherdGood with medical knowledgeGood with interacting with people
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
This talk will focus on
Virtual humans as interaction partners
How can they affect us?
Teach us?
Change us?

Would health profession students treat these virtual human patients differently?

Training
Think of tasks that everyone does almost everyday…
Interact with another person
Yet training for this is very limited.
Humans are social creatures!
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

Training with a VH
Impacts Education (teachers with students) Military (leadership training) Law Enforcement (police officers and suspects)

Benefits of Virtual Humans?
Providing experiences is logistically complex Frequency Standardization Diversity Feedback Resources

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

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

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
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!

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
Repositories
MedEdPORTAL Peer reviewed medical education resource
400 institutions downloads in 10 months
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
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
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
Thank You!
