VR – Public Speaking

In this demo, a social anxiety scenario, the participant delivers a speech in front of an audience. The audience attitude can be varied by the experimenter between different states (e.g., friendly, hostile, and indifferent). The number of avatars and room size can be controlled.

Usage Guidelines

This demo is also intended to serve as a tutorial on how to construct a virtual reality experiment. It can be fully modified and has been designed in a modular format with extensive comments to allow reuse of parts in other experiments. Code is written in the Python programming language and extensive support on programming with Python is provided in the software package and user forums. 3D models from the demo can be reused within the VR platform (only).

Objectives

  1. To set up a virtual world where the participant can give a speech in front of a virtual audience.
  2. To record the physiological responses of the participant as parameters like audience behavior, room size and audience size are varied.

Overview

The participant delivers a speech from behind a podium. The speech text is presented on a monitor on the podium and can be scrolled via a joystick. The room size and number of people (and whether the people are present in the room) are conditions set in advance. During the experiment, the researcher can switch the audience state – e.g., make the audience display boredom, disapproval, etc. Audience behavior is defined using avatar animations and is not limited to the animations included with the demo.

Data analysis

The current state of the audience is marked in the physiological data record, which enables automatic scoring of the data.
