An electroencephalogram (EEG) is a test that measures and records the
electrical activity of brain. Special sensors (electrodes ) are attached to the head and
hooked by wires to a computer. EEG measures voltage fluctuations resulting from
ionic current flows within the neurons of the brain. With technology growing every
day, and stereoscopic 3D televisions becoming commercially available, a question
arises: what kind of effect do 3D movies have on the brain activity and brain signals?
The objective of this project is to have an attempt at answering this question as very
little research has been done in this field. An EEG study was conducted on 30 healthy
participants while watching a series of clips in 2D, stereoscopic 3D using active
glasses and stereoscopic 3D using passive glasses. Their brain activity was recorded,
and analyzed by writing a code in MATLAB to compare between the brain signals in
terms of power, coherence and phase. We focused on the activity in theta and beta
frequency bands. This paper shows that the results revealed a decrease in
concentration in stereoscopic 3D compared to 2D, as well as higher learning behavior
in 2D
