Stereoscopic display visual fatigue detection system based on electrocardiosignals

Abstract

The invention provides a stereoscopic display visual fatigue detection system based on electrocardiosignals. The system comprises a stereoscopic display device used for displaying stereoscopic video, an eye parameter acquisition module used for acquiring stereoscopic vision functions of users and selecting the users participating in experiments, a visual fatigue subjective evaluation module used for acquiring various fatigue symptom values, before and after the users watch the stereoscopic video, of the experimental users, electrocardiosignal acquisition equipment used for acquiring electrocardiosignals, T minutes before the users watch the stereoscopic video and during whole video watching, of the users, a data processing module used for preliminarily judging whether fatigue exists or not according to the fatigue symptom values, carrying out one-way analysis of variance on all indexes and time of the electrocardiosignals and judging that the users are in fatigue when the result judged according to the fatigue symptom values and the result judged according to the electrocardiosignals are identical. According to the system, the subjectively judged result is combined with the judged result based on the electrocardiosignals, and the visual fatigue degree caused by watching stereoscopic display can be easily, rapidly and quantitatively detected.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional stereoscopic display, and in particular relates to a visual fatigue detection system for stereoscopic display based on electrocardiographic signals. Background technique [0002] At present, stereoscopic display technology has been applied more and more in many fields. However, due to technical and cost constraints, the development of stereoscopic display technology is hindered by many obstacles. Among them, a very important factor is that there is a conflict between the imaging principle of stereoscopic display based on binocular parallax and the convergence and adjustment mechanism of human eyes, which makes users experience visual fatigue symptoms such as dizziness and eye pain when watching such stereoscopic videos. The existence of these problems greatly limits the promotion and application of 3D display, and will cause physiological discomfort to users, especially for the elderly ...
