Results VRET Systems

Introduction

On this page you'll find an overview of the VR-systems that are now commercially available for treatment of phobias. It has been constructed through use of a web-based questionnaire and personal communications with developers. The main focus of this study has been to find out what different types of user interfaces have been used in these systems.

Overview

The following table contains mostly data obtained through a web-based questionnaire. Please note that VR-system setups are often flexible and that for the same system sometimes different input and output devices can be used than described here.

* 3DOF indicates a tracker that only measures rotation, 6DOF indicates a tracker that also measures translation

** Control indicates the changes the therapist can make: - Elements : the therapist can alter elements of the VE during the session - Viewpoint : the therapist can change the viewpoint of the patient - Pre-VE modifications : the therapy can make changes to the VE before the session
