EEG based comparative measurement of visual fatigue caused by 2D and 3D displays

Abstract

Visual fatigue is a very important issue of display market to implementing more comfortable display device in terms of human factor. This study is performed in order to measure the visual fatigue using objective evaluation method (i.e., EEG) in 3D display environment. We performed the difference of visual fatigue using a subjective method and compared it to an objective measure. As a result, the 3D content affected the power of brain wave in the beta frequency (14-25 Hz). Beta power was more strong at the viewing the 3D contents. Also, subjective result also showed more strong visual fatigue in the 3D condition than in the 2D condition. We found that visual fatigue significantly appeared amount of power in the beta band between stereoscopic (3D) image and 2D image. © 2011 Springer-Verlag.
