Abstract

A computer-aided-educational method and system that consider a student'"'"'s concentration level when teaching the student. The system monitors automatically more than once the student'"'"'s concentration-sensitive behavior while the student is working on the study materials. Through monitoring the student'"'"'s volitional or involuntary behavior, the system provides an indication on the student'"'"'s concentration level. Based on the indication, the system could react accordingly. Reactions include, for example, providing rewards, punishments, and stimulation, or changing the study materials. The system can also react by asking the student a question to stimulate the student or to assess the student'"'"'s understanding level. Based on the student'"'"'s response, the system may change to more appropriate study materials, or presentation style.

presenting study materials on the subject to the student through the presenter;

monitoring automatically more than once the student'"'"'s concentration-sensitive behavior through the sensor while the student should be studying the materials;

analyzing the monitored results based on one or more rules; and

providing an indication on the student'"'"'s concentration level based on the analysis, where monitoring more than once increases the accuracy of the indication;

such that the behavior can be monitored with the sensor detached from the student.

2. A computer-aided-learning method as recited in claim 1 wherein for the step of monitoring, more than one type of the student'"'"'s concentration-sensitive behavior is monitored.

3. A computer-aided-learning method as recited in claim 1 wherein for the step of monitoring, the behavior monitored is of the same type.

6. A computer-aided-learning method as recited in claim 5 wherein:

the speed of the student'"'"'s inputs is monitored by the sensor; and

one rule is that if the speed of the student'"'"'s volitional inputs across a predetermined period of time is significantly lower than a reference speed, the student has lost concentration in the study materials.

7. A computer-aided-learning method as recited in claim 6 wherein whether a decrease in speed is significant or not depends on the difficulty level of the study materials.

18. A computer-aided-educational method as recited in claim 17 wherein the behavior includes the size of the student'"'"'s pupils.

19. A computer-aided-learning method as recited in claim 1 further comprising the step of reacting according to the indication provided to prevent the student from losing concentration in the study materials.

20. A computer-aided-educational method as recited in claim 19 wherein the reaction includes punishing the student for losing concentration in working on the study materials.

21. A computer-aided-educational method as recited in claim 19 wherein the reaction includes stimulating the student to re-focus on the study materials if the student has lost concentration in the study materials.

22. A computer-aided-educational method as recited in claim 21 wherein if the student has worked on the study materials for a pre-determined amount of time, the reaction includes allowing a student to play a game and then resuming back to the study materials.

23. A computer-aided-educational method as recited in claim 19 wherein the reaction includes changing to a different study materials to present to the student.

24. A computer-aided-learning method as recited in claim 19 wherein the reaction includes asking the student a question.

25. A computer-aided-learning method as recited in claim 24 wherein the study materials to be presented to the student depends on the student'"'"'s response to the question.

26. A computer-aided-learning method as recited in claim 24 wherein the speed of presenting the study materials to the student depends on the student'"'"'s response to the question.

27. A computer-aided-learning method as recited in claim 1 wherein for the step of monitoring, between two consecutive monitoring of the student'"'"'s concentration-sensitive behavior, the method further comprises the step of analyzing the monitored result based on one or more rules.

28. A computer-aided-learning method as recited in claim 1:

further comprising the step of determining a reference for the student; and
