Method and device for dynamic presentation of vr test questions based on counter and brain waves

Abstract

This application discloses a method and device for dynamically presenting VR test questions based on counters and brain waves. The first counter is activated to collect the first brain wave data; a real-time pupil image is obtained; if the gaze is focused on the beginning of the first VR test question, Then activate the second counter to collect the second brain wave data; if the eyes focus on the end of the first VR test question, activate the third counter to collect the third brain wave data; call the standard brain wave data; get the last brain wave data. The time point of electric wave frequency fluctuation; intercept the reference brain wave data segment; calculate the similarity value; if the similarity value is greater than the similarity threshold, activate the fourth counter and continuously collect the fourth brain wave data; Input the data, the second reading, the second brain wave data, the third reading, the third brain wave data, the fourth reading and the fourth brain wave data into the time prediction model to obtain the jump time point; perform the test question jump operation, A second VR test question is presented.

Description

technical field [0001] This application relates to the field of computers, in particular to a method, device, computer equipment and storage medium for dynamically presenting VR test questions based on counters and brain waves. Background technique [0002] In the application of VR technology in the field of education, it has unique advantages in teaching and testing. For example, using VR technology to test the level of students can effectively prevent cheating. Among them, the traditional solution will adopt the way of automatic jumping of test questions in the display process of VR test questions to realize, but different testees need to spend different time on different test questions (there are many reasons, such as human's natural physiological reasons, natural different habits (such as reading speed, way of thinking, etc.) Defects such as waste of time (if the testee does not manually jump or cannot manually jump, he needs to wait) or the amount of data processing in...

Problems solved by technology

Among them, the traditional solution will adopt the method of automatic jumping of test questions in the display process of VR test questions, but different testees need to spend different time on different test questions (there are many reasons, such as human's natural physiological reasons, natural different habit (such as reading speed, way of thinking, etc.) Defects such as waste of time (if the testee does not manually jump or cannot manually jump, he needs to wait) or the amount of data processing increases (need to increase the manual jump mechanism)
