title = "Visual fatigue evaluation of stereoscopic display based on heart rate asymmetry and ordinal pattern statistics",
abstract = "3D display has extensive application potential in the field of virtual reality. However, viewing 3D display for long time tends to induce users' visual fatigue such as headache, dizziness, etc. In order to improve the quality of 3D display and its user-friendliness, it's necessary to uncover the effective metrics which can detect and assess visual fatigue quantitatively and objectively. In order to solve the above-mentioned problem, a fatigue evaluation system is designed in which electrocardiogram (ECG) is studied with the analysis of heart rate asymmetry and ordinal pattern statistics. Subjects being evaluated are asked to watch 3D display for a given period of time and their ECGs are recorded in real time. The analysis of ECG shows that certain physiological indicators change significantly, the state of heart rate of the subjects watching 3D display is different from those without watching any 3D content and the distribution of ordinal pattern statistics reflects the state of visual fatigue.",
