what is a virtual character
What is a Virtual Character?
  • Virtual character - a character who represents the state of a system
  • In TRON (1982), humans and humans that represents software interacted within a world that represented the hardware.

virtual character research
Virtual Character Research
  • Mostly
    • Rendering
    • Animation
    • Artificial Intelligence
  • Newer approaches
    • Affective power
    • Human response to VCs
  • Clinical Psychology
    • Fear of public speaking
motivation
Motivation
  • “Doctor, I have a pain in my side!”
  • What you do next depends on:
    • Age
    • Gender
    • Ethnicity
    • Visual Cues
    • Audio Cues
motivation1
Motivation
  • Current methodologies
    • Books
    • Standardized Patients (actors)
  • Restricted in:
    • Training frequency
    • Scenario variety
    • Immediate feedback
  • Affects medical student preparedness
  • Provide additional training opportunities
solution
Solution
  • Interactive Virtual Characters
    • Life-Sized
    • Computer Generated
    • Natural Interaction
    • Responds to User
    • Responses based on accepted medical procedure
  • COTS Equipment:
    • Projectors
    • Laptops
    • Web cameras
    • Tablet PC
why do we want virtual characters
Why Do We Want Virtual Characters?
  • Propose: Digital Characters as a new (meta-) medium to interact with information
  • Effective Interaction
    • Better than keyboard and mouse for certain tasks
    • Dynamic
    • 3D
    • Natural interaction
    • Low Bandwidth
  • Effective Collaboration
    • Controlled conveyed visual information
    • Non-verbal communication (60%)
let s look at interaction

Responding

Perceiving

Let’s look at interaction
  • Each participant in a communication has three stages: perception, cognition, and response
  • Define interaction as both the input and output
