Virtual reality (VR) offers a new way to treat public speaking anxiety. This study introduces a novel VR environment using Image Based Rendering (IBR) and chroma-key technology for more realistic and controllable exposure therapy.

Area of Science:

  • Psychology
  • Computer Science
  • Virtual Reality Technology

Background:

  • Public speaking anxiety is a prevalent social phobia.
  • Virtual reality (VR) is increasingly used for exposure therapy.
  • Existing VR methods (model-based, movie-based) lack realism and individual control.

Purpose of the Study:

  • To present a novel virtual environment for treating fear of public speaking.
  • To overcome limitations of current VR treatment methods.
  • To enhance realism and user control in VR exposure therapy.

Main Methods:

  • Development of a virtual environment using Image Based Rendering (IBR).
  • Integration of chroma-key technology for individual control of virtual audience members.
  • Implementation of real-time capture techniques for interactive environments.

Main Results:

  • The IBR method creates realistic panoramic virtual environments from digital photos.
  • Chroma-key technology allows for individualized control over virtual audience elements.
  • Real-time capture enables interactive spoken communication within the VR setting.

Conclusions:

  • The combined IBR and chroma-key approach offers a more realistic and controllable VR solution for public speaking anxiety.
  • This technology enhances the potential for effective virtual reality exposure therapy.
  • Future applications may include personalized and interactive therapeutic interventions.
