Mobile Virtual Reality System for Investigation of Subjective Visual Vertical

Abstract

In this study, a mobile virtual reality (VR) based system to perform subjective visual vertical SVV tilt test was developed. The system is able to perform the following tests: static SVV test, two dynamic SVV tests and “realistic” SVV test. The group of 15 healthy young adult volunteers participated in the evaluation study. The system was evaluated in terms of the preferred control method of VR object, by using System Usability Scale questionnaire, and by visual analog scale to evaluate VR induced dizziness. The mobile virtual reality based system is accurate and applicable in the clinical environment. Gamepad based virtual object control method was preferred by the users, so this method should be used in further testing. No virtually induced dizziness was observed in healthy subjects during the tests.
