5 What is VR in Popular Culture?

6 What is VR in Popular Culture?

7 VR in the Real World Expensive Rare Clunky Poor Fidelity but…
Getting Better!

8 What is VR? William Gibson: ‘consensual hallucination’ Jaron Lanier:
‘new post-symbolic paradigm which circumvents representation with a direct experience’

9 Digital Immersive Virtual Environment Technology

12 Defining VR: Virtual Human Avatar

13 Defining VR: Virtual Human Representation

14 Defining VR: Virtual Human Representation

15 Defining VR: Tracking and Rendering

16 Immersive Virtual Environment Apparatus (HMD)

17 Proxemics Studied extensively in the social sciences since 1950’s
Do proxemic patterns hold true with virtual humans? (copresence, social presence)

18 Sample Proxemics Task (Old technology…1999!)

19 Sample Data

20 Mutual Gaze Study: Task

21 Mutual Gaze Study: Conditions

22 Mutual Gaze Study: Results

23 Mutual Gaze Study: Results
Minimum Distance (Virtual Human vs. Control Condition) Meters

24 Virtual Human Representation Study
Agents Independent Variables: Gaze (eyes closed vs. mutual gaze) ‘Soul’ (Agent/Avatar) Avatars

25 Virtual Human Representation: Results
Minimum Distance Meters

26 Approaching Virtual Human Study

27 Virtual Human Approach Results

28 Virtual Human Status/Politeness Effects
Tutor Stranger

29 Application: Virtual Reality and Police Lineups

30 Application: Virtual Reality and Police Lineups
Who Stole the Wallet? Who is the suspect? Currently in US, 90 percent of lineups are from Photographs taken at a single angle (not like the television shows)

31 Application: Virtual Reality and Police Lineups
