2. What is Virtual Reality?

3. Virtual Reality is
Experiencing things through high-
performance computers that don’t
really exist.

4. How about this?

5. Virtual Reality is actually

13. How does Virtual Reality Work?

14. Organism VR Hardware
Surrounding Physical World
Stimulation
Tracking
A Virtual Reality System
• Hardware + Software ≠ Complete VR system
• The organism and its interaction with the hardware are equally important
• Interactions with the surrounding physical world continue to occur during a VR experience
