Problems solved by technology

However, the camera has high requirements on the light. If the desk lamp is turned on at night, it cannot be recognized well; if the student is not facing the camera directly, the facial feature information cannot be collected accurately; and the collection of image information is very easy to leak the privacy of the students, to the lawbreakers. Molecules have an opportunity

Embodiment 1

[0056] When students advance from primary school to junior high school, or from junior high school to high school, the knowledge points they learn continue to become more and more difficult, especially when they need to face the high school entrance examination and college entrance examination. Students often need to accept heavy homework burdens. However, homework is usually set according to the teacher's course progress rather than the student's ability level, and it is difficult to teach students in accordance with their aptitude. And when students are faced with assignments that are too difficult, they will feel that repetition is meaningless and they will not be interested. When the difficulty is too high, you will feel that the topic is too difficult to write and get stuck on a certain question for a long time. Although the difficulty of many assignments is arranged in order of difficulty, for specific students, due to the different proficiency of the knowledge points th...

Embodiment 2

[0069] When a student has a short time, does not want to do homework, and is scribbling on paper, the correlation index must be less than the threshold. At this time, the student is judged to be in a distracted state. If the number of times or the duration exceeds a certain period of time, the status will be pushed through the control terminal to inform the parents. . At this time, in order to avoid misjudgment, turn on the blood oxygen concentration sensor to detect the blood oxygen concentration value of the student. If the blood oxygen concentration value is greater than the threshold value, it means that the student is in a good state of mind and just does not want to do homework; if the blood oxygen concentration value is lower than the threshold value, it is determined The students are in a state of fatigue. At this time, parents need to arrange for the students to do some activities or take a rest before doing homework.

Embodiment 3

[0071] If a student's efficiency in doing questions suddenly drops and they are stumped by a certain question, although the answering handwriting, marking handwriting, and draft handwriting are related to the question, the time to do the question usually far exceeds the average time to do the question. If it is a daily homework, in the case of a lot of homework, it is best to mark this question and put it down first, and then think about it after other questions are finished. Points for intensive training and interpretive analysis.

[0072] This application method uses a smart pen to obtain answer handwriting, marked handwriting, and draft handwriting, and obtains a correlation index through the logical correlation between the above handwriting and the topic, and analyzes the learning status of students writing homework independently through the correlation index and time data. The application method has a high recognition rate and a high judgment accuracy rate, and does not i...

Abstract

The invention discloses a learning state detection method based on a smart paper pen. The method comprises the following step that handwriting currently written by a student and writing actions thereof are collected through a smart pen; according to the questions recorded on the homework paper, handwriting characteristics of each question in the starting and ending time t are counted according to question types, and actions in the starting and ending time t comprise answer handwriting, mark handwriting, draft handwriting and idle time; logic relevance among the answer handwriting, the mark handwriting, the draft handwriting and the question is analyzed to obtain a relevance index; and the control end sends a reminding notice or pushes the state to the parent end. According to the method, the answer handwriting, the mark handwriting and the draft handwriting are obtained through the smart pen, the relevance index is obtained through the logic relevance between the handwritings and the questions, the learning state of the student writing homework alone is analyzed through the relevance index and the time data, and the method is high in recognition rate, high in judgment accuracy, meanwhile, personal privacy of students is not involved, and use is safer.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a learning state detection method based on smart pen and paper. Background technique [0002] In order to improve school safety and facilitate management, monitoring equipment is installed in many classrooms to monitor students' learning or examination conditions. Although the monitoring equipment is suspected of violating the privacy of students, it is convenient for teachers to fully understand the learning situation of students, and it is also convenient for parents to fully understand the learning situation of students. It can also be used as important evidence in case of accidents. [0003] With the reduction of the cost of digital monitoring equipment, many families will also install monitoring equipment to monitor the safety of the home. However, many parents are very busy and cannot accompany their children to urge students to study hard, so various learning monitoring...
