AHFE Open AccessAssessment of visual discomfort during watching 3D and 2D televisions using electroencephalography analysis
Abstract
Three-dimensional (3D) television (TV) is becoming more popular and used for entertainment than the conventional two-dimensional (2D) TV. This study conducted to examine the effect of 3D TV watching on the subjective visual fatigue and EEG data. Thirty male healthy participants (aged 31.4 + 7.1) recruited from the community. We conducted pre- and post- EEG signal collection on participants who watched the same 2D/3D movie content. Additionally, we administered a subjective visual fatigue questionnaire to the participants following the viewing task. The two-way ANOVA was used to verify significant interaction effects of 2D and 3D on before and after watching. A paired-samples t-test was performed for the mean values of subjective questionnaires results to identify significant differences between after watching 2D and 3D movie. Compared with watching 2D TV, 3D TV viewing will cause more fatigue and discomfort. A new evaluation model for 3DTV with beta waveband parameters in seven regions was established, according to the result from EEG data analysis.
