Research from Dongguk University Reveals New Findings on Sensor Research (Quantitative measurement of eyestrain on 3D stereoscopic display considering the eye foveation model and edge information)

By a News Reporter-Staff News Editor at Journal of Technology -- New research on Sensor Research is the subject of a report. According to news reporting originating in Seoul, South Korea, by VerticalNews journalists, research stated, "We propose a new method for measuring the degree of eyestrain on 3D stereoscopic displays using a glasses-type of eye tracking device. Our study is novel in the following four ways: first, the circular area where a user's gaze position exists is defined based on the calculated gaze position and gaze estimation error."

The news reporters obtained a quote from the research from Dongguk University, "Within this circular area, the position where edge strength is maximized can be detected, and we determine this position as the gaze position that has a higher probability of being the correct one. Based on this gaze point, the eye foveation model is defined. Second, we quantitatively evaluate the correlation between the degree of eyestrain and the causal factors of visual fatigue, such as the degree of change of stereoscopic disparity (CSD), stereoscopic disparity (SD), frame cancellation effect (FCE), and edge component (EC) of the 3D stereoscopic display using the eye foveation model. Third, by comparing the eyestrain in conventional 3D video and experimental 3D sample video, we analyze the characteristics of eyestrain according to various factors and types of 3D video. Fourth, by comparing the eyestrain with or without the compensation of eye saccades movement in 3D video, we analyze the characteristics of eyestrain according to the types of eye movements in 3D video."

According to the news reporters, the research concluded: "Experimental results show that the degree of CSD causes more eyestrain than other factors."
