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. like 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 , a...

Abstract

The invention provides a visual attention detection method based on eyeball movement and a system thereof. The method comprises the steps that visual attention test content is displayed through firstdisplay equipment; acquiring a plurality of face images when a testee reads the plurality of E-shaped marks, identifying eye images corresponding to the face images according to the plurality of faceimages, and determining pupil position data of the eye images according to the plurality of eye images, based on the pupil position data, determining fixation point position information of the visualattention test content of the testee on the first display equipment, and determining the visual attention level of the visual attention testee according to the fixation point position information andthe visual attention test content. According to the technical scheme, the visual attention of the visual attention testee can be evaluated automatically, so that the evaluation is more objective, andthe defects of an existing clinical visual attention detection technology are overcome.

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...
