Implementation of a Subjective Visual Vertical and Horizontal Testing System Using Virtual Reality
Abstract
Subjective visual vertical (SVV) and subjective visual horizontal
(SVH) tests can be used to evaluate the perception of verticality and horizontality,
respectively, and can aid the diagnosis of otolith dysfunction in clinical
practice. In this study, SVV and SVH screen version tests are implemented
using virtual reality (VR) equipment; the proposed test method promotes
a more immersive feeling for the subject while using a simple equipment
configuration and possessing excellent mobility. To verify the performance of
the proposed VR-based SVV and SVH tests, a reliable comparison was made
between the traditional screen-based SVV and SVH tests and the proposed
method, based on 30 healthy subjects. The average results of our experimental
tests on the VR-based binocular SVV and SVH equipment were ?0.15?±1.74
and 0.60? ± 1.18, respectively. The proposed VR-based method satisfies the
normal tolerance for horizontal or vertical lines, i.e., a ±3? error, as defined in
previous studies, and it can be used to replace existing test methods.
