Overview l.jpg
Overview

  • What is a digital character?

  • Why do would we want digital characters?

  • Scope of the problem

  • What we want to tackle

  • How we want to tackle it


What is a virtual character l.jpg
What is a Virtual Character?

  • Virtual character - a character who represents an executing system

  • In TRON (1982), humans and humans that represents software interacted within a world that represented the hardware.

What is a Virtual Character

  • We look to to have humans and human the represent software interact in the real world.

Digital characters l.jpg
Digital Characters

  • A new medium to interact with system information

  • Spectrum from the paper clip -> AIBO

  • Examples:

    • Agents (AI, NLP)

    • Robots (Robotics)


Life sized virtual characters l.jpg
Life-Sized Virtual Characters

  • Virtual Characters as a way to interact with information

  • If virtual characters are presented with an adequate level of realism, would people respond to them as they would to other people?

  • Effective Interaction

    • Natural (> than keyboard and mouse)

    • 3D, Dynamic (augmentable)

  • Effective Collaboration

    • Non-verbal communication (60%)

    • High impact?

Digital Characters

  • Advantages:

    • Input: Non-Verbal, privacy

    • Output: Non-Verbal, dynamic

    • Efficacy: Impact, interaction

    • Logistics: Bandwidth, Cost

  • Disadvantages:

    • Input: Non-verbal fidelity

    • Output: Non-verbal fidelity

    • Efficacy: Interaction fidelity

Interaction

  • Each participant in a communication has three stages: perception, cognition, and response

  • Investigate: Display, perception, efficacy

What we plan on studying l.jpg
What we plan on studying

  • There are many components in digital characters

  • We will focus only on interaction

    • Input (perception)

      • How can we have the system capture non-verbal information? (emotion, gestures, eye-gaze, etc.)

      • Proposed solution: Initially straps -> advanced computer vision techniques

    • Output (response)

      • How do we display the digital character?

      • Proposed solution: Evaluate different display technologies

    • Eventually we will look at efficacy (future research)


How we plan on studying it l.jpg
How we plan on studying it

  • Perception:

    • STRAPS: Track head, arms, upper body, and objects (telephone).

    • Develop techniques to transmit eye-gaze and expressions

    • User Studies: Evaluate effectiveness of each component

  • Response:

    • Evaluate the display modality. User Studies:

      • Immersive vs Non-Immersive

      • Life-sized vs. Non-life sized

      • 2D vs 3D

  • Goal: TV + webcams + laptop
