An EEG-based stereoscopic research of the PSD differences in pre and post 2D&3D movies watching

•It was aimed to analyze the moment of transition from Watching to Relax and from Watching to Rest.•We need to emphasize that this is initial research and a preliminary study of our hypothesis.•When people fall asleep, we can claim that they will lose perception of depth, in which there may be a sudden transition from 3D to 2D. Capturing this important moment is main goal.•Our hypothesis is the loss of 3D depth information in fatigue and sleepy situations.•In short, the next research will focus on the transition from 2D to 3D and from 3D to 2D and hopes to see a major change in the driving sector in early detection of the moment of falling asleep and development of alarm systems.
