Analysis of fatigue with 3D TV based on EEG

Fatigue will be induced when people are watching 3D programs on TV. In order to reduce the negative effect, an experiment was conducted to find how3D film can do harm to the health of people. Electroencephalogram (EEG) and electro-oculogram (EOG) were used as an effective method to measure fatigue. When processing EEG signals, we discovered a new method to get blink signals which can also reflect fatigue quite well. This method was firstly used to evaluate the impact after people watching 3DTV. In this study, four segments selected from three 3D films were watched by 8 volunteers. EEG signals were recorded through the whole experiments. The average blink time (the average time people close their eyes when blinking) was calculated by all blink signals extracted from eye movement artifacts in EEG. Independent component analysis (ICA) was used to demonstrate that 3D films with large negative parallax (LNP) and slow displaying speed would induce fatigue easily.
