Effect analysis of horizontal parallax on 3D images comfortableness using EEG

Gao Qiang; Jin Jie; Shen Lili; Hou Chunping

Horizontal parallax is one of important factors that affect 3D images comfortableness. 3D images of different horizontal parallax were used as stimulate signals, by recording the EEG signals, the ERP waveforms of 3D images were extracted. At the same time, behavioral data of comfort experience of the 3D images was recorded and their comfort detection rate was calculated. EEG analysis result shows that no matter in the case of crossed or uncrossed horizontal parallax, comfort range of 3D images horizontal parallax is within 45'. When horizontal parallax is from 45'to 75', the ERP amplitude of around 280 ms is associated with the discomfort level of crossed parallax 3D images and the amplitude of around 250 ms is related to the discomfort level of uncrossed parallax 3D images; Detection rate curve and subjective evaluation results show that comfort range of 3D images horizontal parallax is within 45'. When horizontal parallax is from 45'to 75', the discomfort degree of 3D images is increased. Results show that EEG analysis, detection rate curve and subjective evaluation conclusion is consistent, so EEG can be used to analyze the effect of 3D images comfortableness on horizontal parallax.

Abstract: Horizontal parallax is one of important factors that affect 3D images comfortableness. 3D images of different horizontal parallax were used as stimulate signals, by recording the EEG signals, the ERP waveforms of 3D images were extracted. At the same time, behavioral data of comfort experience of the 3D images was recorded and their comfort detection rate was calculated. EEG analysis result shows that no matter in the case of crossed or uncrossed horizontal parallax, comfort range of 3D images horizontal parallax is within 45'. When horizontal parallax is from 45'to 75', the ERP amplitude of around 280 ms is associated with the discomfort level of crossed parallax 3D images and the amplitude of around 250 ms is related to the discomfort level of uncrossed parallax 3D images; Detection rate curve and subjective evaluation results show that comfort range of 3D images horizontal parallax is within 45'. When horizontal parallax is from 45'to 75', the discomfort degree of 3D images is increased. Results show that EEG analysis, detection rate curve and subjective evaluation conclusion is consistent, so EEG can be used to analyze the effect of 3D images comfortableness on horizontal parallax.
