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.
