USING VIRTUAL REALITY TO IMPROVE SITTING BALANCE A Master’s Thesis Presented to The Graduate College of Missouri State University TEMPLATE In Partial Fulfillment Of the Requirements for the Degree Master of Natural and Applied Science, Computer Science By Alice K. Barnes December 2017 Copyright 2017 by Alice Kay Barnes ii USING VIRTUAL REALITY TO IMPROVE SITTING BALANCE Computer Science Missouri State University, December 2017 Master of Natural and Applied Science Alice K. Barnes ABSTRACT This thesis focuses on using virtual reality (VR) to enhance sitting balance and core strength. It is a study in how to create a VR exercise program which is interesting enough to keep players/patients motivated, but comfortable to play and not overwhelming to the senses. The software used for this study was written with the hope that a later version of it might be used with occupational/physical therapy patients one day. For this master’s thesis, the initial testing has been done with healthy volunteers. The software incorporates what developers know thus far about designing for VR, and it is hoped that later software developers will benefit from knowing the results of this initial round of testing. All of the 39 test participants agreed that the game was fun, with 82% indicating “strongly agree” in the questionnaire. The enthusiastic responses indicate that the game probably has recreational value beyond therapy patients. KEYWORDS: virtual reality, sitting, balance, benefits, drawbacks, core strength, occupational therapy, physical therapy.

Working through pain and tedium are high on this list. Pain and tedium in turn contribute to the overarching challenge of motivation. Many patients give up doing their exercises before reaching their full potential [1]. This thesis explores using virtual reality (VR) to make occupational/physical therapy and exercise in general more fun and motivating. Some of the programs in the past intended for therapy patients and billing themselves as VR programs have been programs that supply an avatar for the patient and provide interaction with a conventional two-dimensional screen. As an example, if one views an OmniVR demonstration video, it is clear that the patients are working in front of a
