Embodiment Construction

[0035] In order to explain the overall concept of the present application more clearly, the following detailed description will be given by way of examples in combination with the accompanying drawings.

[0036] An eye movement-based visual attention detection method and system provided in the embodiment of the present application evaluates the tester's visual attention level through the tester's eye movement information, realizes automatic evaluation of people's visual attention level, and improves visual attention. The objectivity of level evaluation makes up for the deficiency of visual attention detection in existing clinical practice.

[0037] figure 1 It is a schematic diagram of an eye movement-based visual attention detection system provided by an embodiment of the present invention. Such as figure 1 As shown, the above eye movement-based visual attention detection system includes: an eye-tracking device 110 , a first display device 120 , a second display device 130 ...

Abstract

Embodiments of the present application provide a method and system for visual attention detection based on eye movement, the method comprising: displaying visual attention test content through a first display device. Obtain several facial images of the tester when reading multiple E-marks, identify the eye images corresponding to each facial image according to the several facial images, and determine the pupil position data of each eye image according to the several eye images. Based on the pupil position data, determine the tester's fixation point position information on the visual attention test content on the first display device. According to the location information of the fixation point and the content of the visual attention test, the visual attention level of the visual attention tester is determined. Through the above technical solution, the visual attention of the visual attention tester can be evaluated in an automated manner, making the evaluation more objective, thereby making up for the deficiency of the existing clinical visual attention detection technology.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a visual attention detection method and system based on eye movement. Background technique [0002] Eyes are an important way for human beings to obtain external information, and human beings obtain 80%-90% of external information through eyes. During the normal reading process of human beings, even though our eyes are always moving, the fonts we see always remain static, which is mainly related to the visual attention guided by human conscious perception prediction. Eye movement is an important part of neuro-ophthalmology. It needs to be maintained by normal nerve function. It has a series of special functions: it can fix the target of interest on the most sensitive central fovea of ​​the retina, and it can maintain the vision of both eyes. Coordinate the movement and position of the head and body. Eye movements in a broad sense include eye rotation, vergence, accommodation, eye...
