Attention and visual ability training system and method based on eye tracking and intelligent evaluation technology

Abstract

The invention relates to an attention and visual ability training system and method based on the eye tracking and intelligent evaluation technology. The system includes an eye movement tracking module, an evaluation module, an intelligent training module and a storage module. Firstly, an infrared image of the head of a tested person is collected in real time, and the eye movement tracking module determines the eye movement track of the tested person; the attention and visual ability evaluation module shows visual stimulation used for evaluation, and calculates the user's attention and visualability score according to the obtained eye movement track; according to the score, the disclosed attention and visual ability training method is adopted, the training module is used for targeted eyemovement training of the tested person, according to the eye movement track of the user, the module can adjust the training scheme in real time, and the user's attention and visual ability training effects can be achieved. After the user completes training, the evaluation and training results are stored in the storage module. When the user is trained again, no evaluation needs to be conducted.

Description

technical field [0001] The invention relates to the field of scientific instruments, in particular to an attention and visual ability training system and method using eye movement tracking and intelligent evaluation technology. Background technique [0002] Statistics have found that nearly 30% of children have varying degrees of attention deficit and learning disabilities, which may greatly affect academic performance and even physical and mental development. Attention is a selective concentration of perception leading to an increased level of awareness of local stimuli. Research has shown that poor visual information processing is an important factor in attention deficit and learning disabilities. Visual information processing ability includes attention, eye following, eye saccade and other visual abilities. Sight following ability refers to the ability of the eyes to follow a moving target, and sight saccade ability is reflected in the visual breadth, that is, the abili...

Problems solved by technology

This patent partly mentions the content of attention evaluation and training, but the system and method disclosed in this patent have the following disadvantages: first, when the system calculates the attention score, it is based on the position of the fixation point of the subject and the position of the visual stimulus The distance between them is used as a score, but commercial telemetry eye-tracking systems all have an error within 1 degree of viewing angle (the error is about 10mm when the subject is 600mm away from the screen), so the gaze point position estimated by the eye-tracking device The distance from the position of the visual stimulus is the sum of the distance between the actual fixation position and the visual stimulus plus the error value. Since the error value cannot be obtained in real time, the distance between the actual fixation position and the visual stimulus cannot be obtained in real time. Therefore, the The parameters lack accuracy; secondly, the system pays attention to the cognitive level of the testee, and can only give the cognitive score and total score of each item of the testee, and cannot give the testee's attention level based on the analysis of eye movement patterns. patterns of impairment; finally, due to the lack of pattern analysis for classification of attention disorders and only cognitive level scores, the system is unable to provide targeted eye movement training methods; especially although the patent title contains "Training ", the content of the patent also mentions the text of "guided training", but the full text does not give an implementable training method
