This concludes a series of three Medical Physics projects I undertook at University. The project is preceded by the first and second projects.

This project was worth 1/3 of my Masters degree in Physics (4th year). As well as presenting my work in a 30 minute Viva, I produced a 34,500 word dissertation (165 pages), and an additional 1,100 word (8 page) summarised report. The summarised report is published here.

Enhancing Treatment of Visual Vertigo Through Use of Virtual Reality – A Condensed Report

June 15th, 2017

1       Abstract

Virtual environments have been developed to enable treatment of Visual Vertigo (VV) in Virtual Reality (VR). The Oculus Rift DK2 (DK2) is used to view the environments. Tracking data from the headset is recorded for analysis using custom analysis tools. To run the environments, a powerful PC was built with a GTX 1070 and i7-6700.

2       Introduction

This report summarises a full dissertation [1] on treatment of VV through use of VR. For the full context, please see the full dissertation.

The dissertation follows on from previous work, where VR environments were built to facilitate patient treatment inside VR. In this project; existing environments have been modified, analysis tools have been developed to enable compliance testing and data analysis, and custom hardware has been built to run the bespoke software. These events are summarised in this report.

3       Grades

The VR environments contain varying levels of visual stimuli, and are known as grades. A higher grade of environment is more visually stimulating. There are eight grades in a park environment, and eight grades in a beach environment. Visual stimuli is primarily increased with leaves, rain, flying birds; and trees that move in the wind. For full details, please see the dissertation [1]. The current beach environment is shown in Figure 1, and the park environment in Figure 2.
