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 use a controlled stimulus presentation where the participant is exposed to environments with different stimuli.
  2. To record the physiological responses.

For example, in the study of addictions, this paradigm could be used to investigate the relationship between craving, physiological response, and the way the stimulus is presented in the environment.

Overview

The participant is exposed to a sequence of rooms along a corridor that contain different stimulation environments. Four neutral environments and four smoking environments are included, and the environment can be expanded. The number of rooms as well as the objects in the rooms can be modified. The participant does not actively navigate the environment.

Data analysis

Digital markers in the physiological record indicate when the participant is exposed to what condition, which allows for automated data analysis.

Smelling your Emotional State Our sense of smell delivers important information to our brains, such as whether or not food is bad, or reminding us of a pleasant memory (crisp, fall air, anyone?). This fMRI-based study recorded PPG using a Photoplethysmograph Transducer for MRI connected to a PPG100C-MRI Amplifier. A differential pressure transducer continuously recorded variations in […]
