Problems solved by technology

The two measurement methods have their own advantages and disadvantages. Among them, the subjective method is greatly affected by individual differences, and there is no unified quantitative standard, but it is convenient to collect and relatively simple to analyze; the objective measurement data is more accurate and can reflect the physiological and psychological changes of the subjects. It is troublesome to measure and the data analysis is more complicated

Embodiment Construction

[0046] In order to make those skilled in the art understand better, the following in conjunction with the attached figure 1 And attached image 3 This method is further described in detail. Using this method to assess visual fatigue of a stereoscopic movie, the process mainly includes four stages: setting up the environment, practicing demonstration, watching and measuring, and data processing.

[0047] 1. Setting up the environment

[0048] The viewing environment mainly includes a 23-inch polarized glasses-type stereoscopic display, physiological signal measurement equipment, a rotatable mobile seat and a host. The brightness, contrast and other parameters of the display are set to recommended values ​​(ITU-R BT.500). The physiological signal measurement device is placed on the desktop on the left hand side of the user. On the ground at a distance of 3 times the screen height (87 cm) from the plane where the stereoscopic display is located, mark the seat position with a...

Abstract

The invention discloses a three-dimensional display visual fatigue evaluation system and method based on electrocatdiogram and electrooculogram signals. The system comprises a three-dimensional display device, a subjective visual fatigue continuous scoring device, a physiological signal measurement device and a data processing unit, wherein the subjective visual fatigue continuous scoring device is used for collecting a user visual fatigue score value SS when the user watches three-dimensional display resources on the three-dimensional display device; the physiological signal measurement device is used for collecting ECG and EOG when the user watches three-dimensional display resources on the three-dimensional display device; and the data processing unit is used for calculating physiological feature data of the user according to the collected ECG and EOG, modeling according to the physiological feature data and the SS to obtain a three-dimensional visual fatigue prediction model, and evaluating the visual fatigue data of target three-dimensional display resources to the user i according to the physiological feature data when the user i watches the three-dimensional display resources and the three-dimensional visual fatigue prediction model.

Description

technical field [0001] The invention belongs to the field of three-dimensional display evaluation, and in particular relates to a three-dimensional display visual fatigue evaluation system and method based on electrocardiogram and electrooculogram signals. Background technique [0002] With the development of stereoscopic display technology, stereoscopic display products have been widely used in many industries, and are very popular because they can bring more immersion and presence to users. However, due to the conflict between the imaging principle of the stereoscopic display technology itself and the working mechanism of human vision, the side effects of 3D display cannot be ignored. For example, watching stereoscopic images or videos for a long time will make the viewer feel eye fatigue, dizziness, vomiting and other discomforts. There are even studies showing that viewing stereoscopic displays may have long-term effects or irreversible damage to people's health. These...
