Physiological Responses to Watching 3D on Television with Active and Passive Glasses

Abstract

The aim of this study was to evaluate the relationship between teenager's emotional states while watching 3D on TV using active (shutter) and passive (filter) glasses and specific physiological indices. The physiological measures include electroencephalography (EEG) for beta wave at occipital lobe (O 1 and O 2 regions), electrooculography (EOG) for eye blinking rate from the dominate eye, and subjective evaluation. Eighteen healthy teenager's (9 used active glass and 9 used passive glasses) aged 18.72±0.56 years were participated. The subjects were exposed to 3D visuals for 45 min each. The relative beta band power was comparatively higher while using passive glasses. The eye blink rate was comparatively higher while using passive glasses. Subjective evaluation scores were comparatively higher while using active glasses. The contrary results between physiological responses and psychophysical were observed. Further experiments need to be performed by considering more subjects, higher viewing duration and light weight glasses.

Effects of Viewing Displays from Different Distances on Human Visual System

“…The two independent variables based on the repeated measures or within the subject variable were (C) viewing time (pre-test, T10, T20, T30, T40, T50, T60, and post-test) and (D) movies (Jurassic World, Avengers, San Andreas, and Godzilla). Park et al [5,40] selected the viewing duration to be 45 min; however, Chen et al [41] used 10 min, and Park et al [38] used 1 h as the viewing period. Hence, in this study, it was decided to perform the experiment for 60 min.…”

“…Numerous studies have been conducted to evaluate the visual fatigue caused because of watching 3D displays using electroencephalogram (EEG) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The EEG method is selected as it is the most significant and reliable physiological measure for evaluating mental fatigue [17][18][19][20][21].…”

“…Park et al [5] assessed the connection between the emotional states of a teenager and relative β-band power at occipital lobe region while viewing 3D TV using some active and some passive glasses. The results showed that the relative β-band power was relatively higher while using passive (filter) glasses when compared to using active (shutter) glasses.…”

“…The results showed that the relative β-band power was relatively higher while using passive (filter) glasses when compared to using active (shutter) glasses. Active 3D glasses interact wirelessly with images on a screen to enhance 3D viewing, whereas passive glasses do not [5]. With passive 3D glasses, the TV screen is coated so that light from alternate scan lines is polarized differently.…”

“…Previous studies have focused on spectral variations in the various EEG frequency bands [5][6][7][8][9][10]17,[25][26][27]. It has often been hypothesized that through changes in attention or onset of visual fatigue, the low-frequency waves in the EEG such as δ, θ, and α will increase, while the higher frequency waves such as β will decrease.…”
