Description

  The present invention relates to a question control program and the like.

  In recent years, elementary and junior high school education sites have distributed tablet terminals to students and used them as teaching materials for electronic learning. For example, a teacher registers data of a problem sheet to be a homework in a tablet terminal, and a student takes the tablet terminal home or the like to solve a problem on the problem sheet.

  The use of tablet terminals as described above is generally referred to as “take-out learning”, and the need for take-out learning is increasing with the spread of tablet terminals. In addition, it is important to establish learning habits for children, and it is required to appropriately assign learning tasks at home.

  However, the above-described conventional technique has a problem in that it cannot effectively give a problem according to the user's state.

  For example, in a home environment, it is difficult for children to learn while keeping their concentration and motivation, and as a result, effective take-out learning is not possible.

  In one aspect, an object of the present invention is to provide a question control program, a question control method, and a question control device that can control the difficulty level of questions according to the degree of user concentration.

  In the first plan, the computer executes the following processing. The computer displays the problem on the display unit. The computer measures the concentration of users who input answers to questions. The computer controls the number of questions to be set and / or the difficulty level of the questions to be set according to the measured concentration.

  The difficulty level of the question to be asked can be controlled according to the user's concentration level.

  Embodiments of a question control program, a question control method, and a question control device disclosed in the present application will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  FIG. 1 is a functional block diagram illustrating the configuration of the question control apparatus according to the present embodiment. For example, the question control device 100 corresponds to a PC (Personal Computer), a notebook PC, a tablet terminal, a smartphone, or the like. As illustrated in FIG. 1, the question control apparatus 100 includes a camera 110, a communication unit 120, an input unit 130, a display unit 140, a storage unit 150, and a control unit 160.

  The camera 110 is a camera that captures a moving image in the shooting range. For example, the camera 110 captures a moving image of the face of the user who operates the question control apparatus 100, and outputs information of the captured moving image of the face to the control unit 160. In the following description, information on a moving image of a face photographed by the camera 110 is referred to as face image data.

  The communication unit 120 is a processing unit that performs data communication with other external devices via a network. The communication unit 120 corresponds to a communication device. For example, the communication unit 120 communicates with an external device used by the teacher, and receives a problem table 152 (to be described later), transmits a problem answer table 153, and the like.

  The input unit 130 is an input device for a user such as a student to perform various inputs. The input unit 130 corresponds to a keyboard, a mouse, a touch panel, or the like. For example, the user operates the input unit 130 to answer each question on the question sheet displayed on the display unit 140.

  The display unit 140 is a display device that displays various types of information output from the control unit 160. The display unit 140 corresponds to a liquid crystal display, a touch panel, or the like. For example, the display unit 140 displays problem sheet information output from the control unit 160.

  The storage unit 150 includes a selection criterion table 151, a question table 152, and a question answer table 153. The storage unit 150 corresponds to a semiconductor memory device such as a random access memory (RAM), a read only memory (ROM), and a flash memory, and a storage device such as a hard disk drive (HDD).

  The selection criteria table 151 is a table showing selection criteria related to the difficulty level of the next problem sheet to be presented to the user. FIG. 2 is a diagram illustrating an example of the data structure of the selection criterion table. As shown in FIG. 2, in this selection criterion table 151, the difficulty level of the next question sheet is specified in accordance with the combination of the correct answer rate and the degree of concentration. The correct answer rate indicates the correct answer rate of the current question sheet. The degree of concentration indicates the degree of concentration of the user who answered the current question sheet. For example, the correct answer rate and the degree of concentration are classified as high, medium, or low.

  For example, if the user's concentration is “high”, the difficulty level of the next question sheet is “high difficulty” or “same difficulty” depending on the correct answer rate “high”, “medium”, or “low”. "Degree" and "same difficulty". When the user's concentration level is “medium”, the difficulty level of the next question sheet is “high difficulty level” or “same difficulty level” depending on the correct answer rate “high”, “medium”, or “low”. , "Low difficulty". If the user's concentration level is “low”, the difficulty level of the next question sheet is “same difficulty level” or “low difficulty level” depending on the correct answer rate “high”, “medium”, or “low”. , "Low difficulty".

  In the selection criterion table 151, “high difficulty level” indicates that the difficulty level of the next problem sheet is set to a difficulty level that is one level higher than the difficulty level of the current problem sheet. When the difficulty level of the current problem sheet is “high”, the difficulty level of the next problem sheet is also “high”.

  In the selection criterion table 151, “same difficulty level” indicates that the difficulty level of the next problem sheet is set to the same difficulty level as that of the current problem sheet.

  In the selection criterion table 151, “low difficulty level” indicates that the difficulty level of the next problem sheet is set to the difficulty level one level lower than the difficulty level of the current problem sheet. When the difficulty level of the current problem sheet is “low”, the difficulty level of the next problem sheet is also “low”.

  The question table 152 is a table that holds information on question sheets that are given to the user. FIG. 3 is a diagram illustrating an example of the data structure of the problem table. As shown in FIG. 3, this question table 152 associates a question sheet ID, a required flag, the number of questions, a total score, a difficulty level, a question sheet, and answer data.

  The problem sheet ID is information for uniquely identifying the problem sheet. The essential flag is information indicating whether or not the corresponding question sheet is essential as an answer target. The essential flag of the essential problem sheet is “1”, and the essential flag of the non-essential problem sheet is “0”.

  The number of problems indicates the number of problems included in the corresponding problem sheet. The total score indicates the total score of the corresponding problem sheet. The difficulty level indicates the difficulty level of the corresponding problem sheet. The problem sheet is data of a problem sheet corresponding to the problem sheet ID. The answer data is answer information for each question included in the question sheet.

  The question answer table 153 is a table that holds information on the user's answer result for the question sheet, the user's concentration degree when answering the question sheet, and the correct answer rate. FIG. 4 is a diagram illustrating an example of a data structure of the question answer table. As shown in FIG. 4, the question answer table 153 associates a user ID, a question sheet ID, answer data, the number of blinks, a degree of concentration, and a correct answer rate (%).

  The user ID is information that uniquely identifies the user. The question sheet ID is information that uniquely identifies the question sheet that the user has answered. The answer data is user's answer information for each question on the question sheet.

  The number of blinks indicates the number of blinks of the user during the measurement period. In this embodiment, as an example, the number of blinks is the number of blinks per minute. For example, the start time of the measurement period is set as the time when the answer to the question sheet with the corresponding question sheet ID is started. The end time of the measurement period is the time when the answer to the question sheet with the corresponding question sheet ID is finished.

  The degree of concentration indicates the degree of concentration when the user is answering the question sheet. For example, the degree of concentration is classified into “low”, “medium”, and “high” according to the number of blinks. It is known that when the number of blinks is small, the degree of concentration is high, and when the number of blinks is large, the degree of concentration is low. In this embodiment, as an example, when the number of blinks per minute is “less than 10”, the concentration is set to “high”. When the number of blinks per minute is “11 times or more and less than 20 times”, the concentration is set to “medium”. When the number of blinks per minute is “21 times or more”, the concentration is set to “low”.

  The correct answer rate (%) indicates the correct answer rate of the user's answer to the corresponding question sheet. Although not shown here, the correct answer rate (%) is classified into one of “high”, “medium”, and “low”. For example, when the correct answer rate (%) is “80% or more”, the correct answer rate is set to “high”. When the correct answer rate (%) is “60% or more and less than 80%”, the correct answer rate is set to “medium”. When the correct answer rate (%) is “less than 60%”, the correct answer rate is set to “low”.

  The control unit 160 includes a measurement unit 161, a calculation unit 162, a difficulty level control unit 163, and a display control unit 164. The difficulty level control unit 163 is an example of a control unit. The control unit 160 can be realized by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. The control unit 160 can also be realized by a hard-wired logic such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).

  The measuring unit 161 is a processing unit that measures the degree of concentration based on the user's behavior identification. In this embodiment, as an example, the number of blinks of the user is measured, and the degree of concentration is measured based on the number of blinks.

  An example of processing in which the measurement unit 161 measures the number of blinks of the user will be described. The measuring unit 161 acquires face image data from the camera 110 and compares the face image data with the face template to identify the eye region. The measuring unit 161 determines that the user has open eyes when white eyes or black eyes are detected for the specified eye region. The measuring unit 161 determines that the user has closed the eyes when the white eye or the black eye is not detected for the specified eye region. The measuring unit 161 determines that the eye area blinks once when the eyes of the eye area are “open”, “closed”, and “open” for consecutive frames of the face image data. In addition, the said process is an example and the measurement part 161 may determine a user's blink using the sensor etc. which detect blink.

  The measuring unit 161 counts the number of blinks during the measurement period. The measurement unit 161 sets the disclosure time of the measurement period as the time when the user inputs the answer to the first question included in the question sheet. The measurement unit 161 sets the end time of the measurement period as the time when the answer to the last question for the question sheet is input. For example, the measurement unit 161 is connected to a timer (not shown).

  After measuring the number of blinks during the measurement period, the measurement unit 161 calculates the number of blinks per minute by dividing the number of blinks by the measurement period (minutes). The measurement unit 161 registers the number of blinks per minute in the question answer table 153 in association with the user ID and the question sheet ID. Further, the measuring unit 161 classifies the degree of concentration into “low”, “medium”, or “high” according to the number of blinks per minute, and the divided results are set as a user ID and a problem sheet ID. Correspondingly, it is registered in the problem answer table 153.

  It is assumed that the measurement unit 161 acquires information on the current problem sheet ID from the display control unit 164. Further, when answering the question sheet, the user operates the input unit 130 to input his / her user ID to the question control apparatus 100.

  The calculation unit 162 is a processing unit that calculates the correct answer rate of the user for the current question sheet. The calculation unit 162 acquires information about the current problem sheet ID from the display control unit 164. The calculation unit 162 acquires answer data corresponding to the current question sheet ID from the question table 152. The calculation unit 162 calculates the correct answer rate (%) by referring to the question answer table 153 and comparing the answer data corresponding to the current question sheet ID with the answer data. The calculation unit 162 registers the correct answer rate as a calculation result in the question answer table 153 in association with the user ID and the question sheet ID.

  The difficulty level control unit 163 is a processing unit that controls the difficulty level of the next question sheet based on the user's concentration level and correct answer rate with respect to the current question sheet. The difficulty level control unit 163 acquires information on the current problem sheet ID from the display control unit 164. For example, the difficulty level control unit 163 outputs information on the difficulty level of the next problem sheet to the display control unit 164.

  The difficulty level control unit 163 acquires information on the user's concentration level and correct answer rate with respect to the current question sheet from the question answer table 153. In addition, the difficulty level control unit 163 compares the concentration level and the correct answer rate with the selection criterion table 151 to determine which of the “high difficulty level”, “same difficulty level”, and “low difficulty level” is applicable. Determine.

  The difficulty level control unit 163 determines the difficulty level of the current problem sheet based on the current problem sheet ID and the problem table 152. When the difficulty level of the current problem sheet is “high” and the information obtained from the selection criterion table 151 is “high difficulty level”, the difficulty level control unit 163 sets the difficulty level of the next problem sheet to “high”. Is determined. When the difficulty level of the current problem sheet is “medium” and the information obtained from the selection criterion table 151 is “high difficulty level”, the difficulty level control unit 163 sets the difficulty level of the next problem sheet to “high level”. Is determined. When the difficulty level of the current problem sheet is “low” and the information obtained from the selection criterion table 151 is “high difficulty level”, the difficulty level control unit 163 sets the difficulty level of the next problem sheet to “medium”. Is determined.

  When the difficulty level of the current problem sheet is “high” and the information obtained from the selection criterion table 151 is “same difficulty level”, the difficulty level control unit 163 sets the difficulty level of the next problem sheet to “high”. Is determined. When the difficulty level of the current problem sheet is “medium” and the information obtained from the selection criterion table 151 is “same difficulty level”, the difficulty level control unit 163 sets the difficulty level of the next problem sheet to “medium”. Is determined. When the difficulty level of the current problem sheet is “low” and the information obtained from the selection criterion table 151 is “same difficulty level”, the difficulty level control unit 163 sets the difficulty level of the next problem sheet to “low”. Is determined.

  When the difficulty level of the current problem sheet is “high” and the information obtained from the selection criterion table 151 is “low difficulty level”, the difficulty level control unit 163 sets the difficulty level of the next problem sheet to “medium”. Is determined. When the difficulty level of the current problem sheet is “medium” and the information obtained from the selection criterion table 151 is “low difficulty level”, the difficulty level control unit 163 sets the difficulty level of the next problem sheet to “low”. Is determined. If the difficulty level of the current problem sheet is “low” and the information obtained from the selection criterion table 151 is “low difficulty level”, the difficulty level control unit 163 sets the difficulty level of the next problem sheet to “low”. Is determined.

  The display control unit 164 is a processing unit that acquires problem sheet information corresponding to the difficulty level acquired from the difficulty level control unit 163 from the problem table 152 and causes the display unit 140 to display the acquired problem sheet information. The display control unit 164 outputs information on the current problem sheet ID being displayed on the display unit 140 to the measurement unit 161, the calculation unit 162, and the difficulty level control unit 163.

  The display control unit 164 selects the first problem sheet by executing the following process. The display control unit 164 refers to the question table 152 and selects a question sheet from the question sheets whose essential flag is “1”. The display control unit 164 proceeds to the selection of the question sheet according to the degree of concentration / accuracy rate after all the questions whose essential flag is “1” have been issued. If the difficulty level of the problem sheet that the user can solve for the first time is set in advance, the problem sheet having the set difficulty level and the required flag “1” is selected.

  The display control unit 164 asks the required flag “1” for the problem sheet to be selected after the second time, and if the required flag “1” has no problem with the corresponding difficulty level, the corresponding difficulty with the required flag “0”. Choose a degree problem. As described above, the display control unit 164 selects information on the problem sheet corresponding to the difficulty level acquired from the difficulty level control unit 162 from the problem table 152. If there are a plurality of problem sheets to be selected, one of the unselected problem sheets is selected. When all the problem sheets to be selected are selected, the display control unit 164 ends the process of selecting and displaying the problem sheet.

  For example, it is assumed that the display control unit 164 acquires the difficulty level “high” from the difficulty level control unit 163 when selecting the problem sheet from the second time. In this case, the display control unit 164 selects the problem sheet corresponding to any one of the problem sheet IDs “8, 9” with reference to the problem table 152 shown in FIG. Display on the unit 140.

  If any one of the problem sheet IDs “8, 9” has been selected, the display control unit 164 selects the problem sheet corresponding to the unselected problem sheet ID and causes the display unit 140 to display the problem sheet. When both of the problem sheet IDs “8, 9” have been selected, the display control unit 164 ends the display of the problem sheet. It is assumed that the display control unit 164 holds the selected problem sheet ID.

  When the display of the question sheet is terminated, the display control unit 164 generates scoring result information and causes the display unit 140 to display it. FIG. 5 is a diagram illustrating an example of scoring result information. For example, information on the number of correct answers, the score, and the degree of concentration is displayed in the scoring result. The display control unit 164 may generate a scoring result for each question sheet. For example, when the “next sheet” button is pressed, scoring result information corresponding to another question sheet is displayed. .

  By the way, the above-described difficulty level control unit 163 determines the difficulty level of the next question sheet based on the concentration level and the correct answer rate, but is not limited thereto. For example, the difficulty level controller 163 may control the number of problem sheets according to the degree of concentration. In this case, the difficulty level control unit 163 determines that the higher the degree of concentration, the larger the number of questions. For example, when the degree of concentration is “high”, the difficulty level control unit 163 causes the display control unit 164 to answer all questions on the problem sheet. When the degree of concentration is “medium”, the difficulty level control unit 163 causes the display control unit 164 to issue 80% of the problems on the problem sheet. When the degree of concentration is “low”, the difficulty level control unit 163 causes the display control unit 164 to issue 50% of the problems on the problem sheet. The ratio shown here may be appropriately set by a teacher or the like.

  Next, an example of a processing procedure of the question control apparatus according to the present embodiment will be described. FIG. 6 is a flowchart illustrating the processing procedure of the question control apparatus according to the present embodiment. As shown in FIG. 6, the display control unit 164 of the question control apparatus causes the display unit 140 to display information on the question sheet whose essential flag is “1” (step S <b> 101).

  The question control apparatus 100 starts accepting answers to the current question sheet (step S102). The measuring unit 161 of the question control unit 100 measures the number of blinks (step S103). The question control apparatus 100 ends acceptance of the answer to the current question sheet (step S104).

  The calculation unit 162 of the question control apparatus 100 calculates the correct answer rate of the current question sheet (step S105). The measuring unit 161 of the question control apparatus 100 specifies the concentration degree based on the number of blinks (step S106).

  When the selection of all question sheets has been completed (step S107, Yes), the display control unit 164 displays information on the scoring results (step S108). On the other hand, if the selection of all question sheets has not been completed (No at Step S107), the display control unit 164 proceeds to Step S109.

  The difficulty level control unit 163 of the display control unit 164 determines the difficulty level of the next question sheet based on the selection criterion table 151, the correct answer rate, and the concentration level (step S109). The display control unit 164 determines whether there is an unquestioned question sheet corresponding to the difficulty level (step S110). If there is no unselected problem sheet corresponding to the degree of difficulty (No at Step S110), the display control unit 164 proceeds to Step S108.

  On the other hand, if there is an unselected question sheet corresponding to the degree of difficulty (Yes in step S110), the display control unit 164 proceeds to step S111. The display control unit 164 selects and displays one question sheet from unselected question sheets corresponding to the difficulty level (step S111), and proceeds to step S102.

  Next, effects of the question control apparatus 100 according to the present embodiment will be described. The question control device 100 displays a question sheet, measures the concentration of the user, and determines the difficulty level and / or the number of questions of the next question sheet based on the measured concentration, Control the difficulty level of questions based on concentration. Thus, the difficulty level of questions can be controlled according to the user's concentration level. For example, users with high concentration can solve many problems with high difficulty, and users with low concentration can solve problems with low difficulty so that problems suitable for the user's condition can be solved. You can ask questions by degree and number of questions.

  The question control apparatus 100 measures the number of blinks of the user, determines that the degree of concentration decreases as the number of blinks increases, and controls the number of questions to be raised according to the decrease in the degree of concentration. Thereby, a user's concentration degree can be measured with a sufficient precision and the measurement according to the concentration degree can be performed. In addition, when the degree of concentration is low, control to reduce the number of problems or control to simplify the difficulty is performed, so that difficult problems and many problems can be prevented from being answered when the user is not concentrated. .

  The question control device 100 determines the difficulty level of the next question sheet based on the user's degree of concentration and the correct answer rate regarding the current question sheet. Therefore, it is possible to adjust the number of problems and the difficulty level based on the concentration level and the correct answer rate of the latest user.

  By the way, although the measurement part 161 of the question control apparatus 100 measured the user's degree of concentration using the number of blinks in the measurement period as the behavior characteristic, it is not limited to this. For example, the measurement unit 161 may measure the degree of user concentration based on behavior identification other than the number of blinks. For example, the measurement unit 161 may use a user's line of sight, answer content, answer time, speed, number of taps in a predetermined time, number of scrolls, and the like as action characteristics.

For example, when measuring the degree of concentration with the user's line of sight, the time during which the line of sight is directed to the display 203 is measured, and the longer the time that the line of sight is directed, the higher the degree of concentration can be determined.
Further, when the concentration level is measured based on the answer contents, it can be determined that the concentration level is lower as the number of writing mistakes and the number of rewrites increases. Further, when the concentration level is measured by the answer time and the speed, it can be determined that the higher the answer time and the speed of inputting the answer, the higher the concentration level. Further, when the degree of concentration is measured by the number of taps in a predetermined time, it can be determined that the degree of concentration is low because the larger the number of taps, the more unnecessary input is considered. Further, when the concentration level is measured by the number of scrolls, it can be determined that the greater the number of scrolls, the more useless operations, and the lower the concentration level. Note that the measurement and determination criteria of the concentration level based on these behavior characteristics are examples, and any behavior characteristics and criteria may be used as long as the user's concentration level can be determined.

  By determining the concentration level based on such behavioral characteristics, it is possible to measure the concentration level according to the user's implementation environment. For example, when learning is performed on a tablet terminal, the degree of concentration can be determined based on behavioral characteristics unique to operations on the tablet terminal.

  Next, an example of a hardware configuration of a computer that realizes the same function as the question control apparatus 100 shown in the above embodiment will be described. FIG. 7 is a diagram illustrating an example of a hardware configuration of a computer that implements the same function as the question control apparatus.

  As illustrated in FIG. 7, the computer 200 includes a CPU 201 that executes various arithmetic processes, an input device 202 that receives input of data from a user, and a display 203. The computer 200 also includes a reading device 204 that reads a program and the like from a storage medium, and an interface device 205 that exchanges data with another computer via a wireless network. The computer 200 has a camera 206. The computer 200 also includes a RAM 207 that temporarily stores various types of information and a hard disk device 208. The devices 201 to 208 are connected to the bus 209.

  The hard disk device 208 includes a measurement program 208a, a calculation program 208b, a difficulty level control program 208c, and a display control program 208d. The CPU 201 reads out the measurement program 208 a, the calculation program 208 b, the difficulty level control program 208 c, and the display control program 208 d and develops them in the RAM 207.

  The measurement program 208a functions as a measurement process 207a. The calculation program 208b functions as a calculation process 207b. The difficulty level control program 208c functions as the difficulty level control process 207c. The display control program 208d functions as a display control process 207d.

  The process of the measurement process 207a corresponds to the process of the measurement unit 161. The process of the calculation process 207 b corresponds to the process of the calculation unit 162. The processing of the difficulty level control process 207c corresponds to the processing of the difficulty level control unit 163. The process of the display control process 207d corresponds to the process of the display control unit 164.

  Note that the programs 208a to 208d are not necessarily stored in the hard disk device 208 from the beginning. For example, each program is stored in a “portable physical medium” such as a flexible disk (FD), a CD-ROM, a DVD disk, a magneto-optical disk, and an IC card inserted into the computer 200. Then, the computer 200 may read and execute the programs 208a to 208d.
