Description

The present invention relates to a technique for supporting an online test.

In recent years, ICT (Information and Communication Technology) of education has progressed, and online education has begun to permeate. In particular, in 2020, a request was made to refrain from going out to prevent the spread of infectious diseases, and online education became widespread as a practical means. Taking this opportunity, online education is expected to form a new social foundation.

In online education, students and students may study at home using computers such as personal computers and tablet terminals. In addition, not only taking classes at home, but also taking exams at home. In other words, the exam content provided by the school side is expanded on the computer, the questions included in the exam content are solved, and the in-school test and the mock test are performed in the form of replying the answer.

Japanese Patent Publication No. 2001-510593

However, in online testing (hereinafter referred to as "online testing"), the problem is how to prevent fraud. It is not possible for a teacher (supervisor) to directly supervise each student or student (examinee) as in a normal exam conducted in a school classroom.

Patent Document 1 discloses "a system for controlling the operation of a safe test conducted at a remote test station and remotely supervised". In this example, the examinee is photographed by a video camera and the image is used for fraud prevention. Specifically, personal authentication is performed using the video of the examinee as data showing physical characteristics. This prevents the replacement examination. For other frauds, the video is only recorded and made available to the supervisor to assist the director. Therefore, Patent Document 1 has a problem that the load on the supervisor for preventing cheating and the like is large. In particular, the effort to supervise many examinees alone in a communication environment is large and is likely to be overlooked, unlike the case of direct supervision in a classroom. This leads to the problem that test takers are prone to fraud.

The present invention is an invention completed based on the above-mentioned problem recognition, and a main object thereof is to provide a technique for deterring fraudulent activity in an online test.

The online test support device according to an embodiment of the present invention is an online test support device capable of communicating with a test taker terminal and a supervisor terminal via a network, and the test taker video and audio being tested are transmitted from the test taker terminal. A video / audio receiver that continuously receives, a monitoring unit that detects prohibited objects, fraudulent acts, suspicious acts, or third parties in the examination based on the video and audio of the examinee, prohibited objects, fraudulent acts, It has a warning notification unit that sends a warning notification to the supervisor terminal when a suspicious act or a third party is detected.

According to the present invention, fraudulent activity in online tests can be suppressed. This will enable proper and smooth online testing.

[Embodiment]
FIG. 1 is a network configuration diagram of an online test system.
The online exam system allows you to take exams at home, such as at school or cram school. Students and students who are candidates take the test using a computer such as a notebook personal computer or a tablet terminal at home. Alternatively, you may take the test using the personal computer provided in a shared environment such as a self-study booth. In the following, the computer used by the examinee will be referred to as the examinee terminal 100. FIG. 1 shows how four examinees use the examinee terminals 100a to d (hereinafter, collectively referred to as “examinee terminal 100” when collectively referred to or not particularly distinguished). In the case of an examination conducted on a class-by-class basis, students and students in that class use the examinee terminal 100 in the same manner.

The examinee terminal 100 can connect to the online test server 200 via the Internet. The test questions delivered from the online test server 200 are displayed on the test taker terminal 100, and the test taker solves the test questions and operates the test taker terminal 100 to input the answer.

In addition, the online examination system captures the situation during the examination with video and audio so that the supervisor can supervise each examinee. In a normal examination where examinees gather in a classroom or examination venue, a supervisor will be present to supervise the examinees. However, when taking an examination at home, the supervisor cannot be present at each home, so the supervisor remotely supervises each examinee. Supervisors are, for example, school teachers and cram school teachers.

As the examinee terminal 100, for example, a notebook personal computer having a built-in WEB camera is used so that the examinee can be photographed. Notebook personal computers also have a microphone for inputting ambient sounds.

The video showing the examinee and the surrounding sound are sent from the examinee terminal 100 to the online test server 200. The online test server 200 relays the video and audio and sends them to the supervisor terminal 300. The supervisor terminal 300 used by the supervisor is a computer such as a notebook personal computer or a tablet terminal. Here, it is assumed that a notebook personal computer having a built-in WEB camera is used as the supervisor terminal 300 as in the examinee terminal 100. The supervisor is suspicious of cheating or cheating by the video showing each examinee displayed on the supervisor terminal 300 and the sound during the test output from the speaker of the supervisor terminal 300. Check if any actions have been taken.

The online test server 200 also performs a process of supporting supervision by an AI (artificial intelligence) function. Specifically, it recognizes the video showing each examinee and the audio during the test, and automatically detects fraudulent acts or suspicious acts that may be fraudulent. When the online test server 200 detects a cheating or suspicious act of a certain examinee, the screen displaying the image of the examinee in a large size and the voice of the examinee are sent to the supervisor terminal 300. .. This allows the supervisor to focus on the examinee's supervision and make the right decisions. In this way, even if it is automatically monitored by the AI function, the examinee has the impression that it is being monitored by the observer. Therefore, the psychology of restraining the examinee works, and cheating such as cheating is naturally suppressed.

FIG. 2 is a screen view showing an example of the test content screen 110.
The test content distributed from the online test server 200 to each test taker terminal 100 includes image data of the test question 112 and structured data of the answer column 114.

The examinee terminal 100 is provided with a browser. The browser of the examinee terminal 100 displays the examination content screen 110, which is a WEB page. Exam questions 112 are displayed on the left side of the exam content screen 110. Exam question 112 is composed of a plurality of questions. On the right side of the test content screen 110, an answer column 114 in which buttons corresponding to the choices of each question are arranged is displayed based on the structured data.

Candidates read and solve each question displayed on the left side. This figure shows an example of a selection-type question that selects the correct answer from 1 to 4 answer candidates. If the examinee thinks that the option "3" is the correct answer for question 1, he / she clicks the box of "3" corresponding to question 1 in the answer column 114. Then, a check mark is displayed in the box, and the selection number "3" for Question 1 is internally retained. The same is true for other problems.

When the test is completed, the internally held answer, that is, the selection number for each question, is transmitted to the online test server 200. This process corresponds to the submission of an answer sheet in a normal examination.

The online test server 200 checks the behavior of each test taker during the test. The WEB camera built into the notebook personal computer is installed toward the user. In other words, the WEB camera shows the state of the examinee who is taking the examination. The video of the examinee taken by the WEB camera is sent to the online test server 200 at any time. The video is a moving image or a periodic still image.

Here, we focus on four types of cheating: "unauthorized absence", "book browsing", "smartphone browsing", and "third-party advice".

"Unauthorized absence" will be explained. It is okay for the examinee to leave the seat after refusing the supervisor and obtaining permission. Therefore, the online testing system can call for permission. The process by which the examinee calls on the supervisor will be described later. If the test taker leaves, he or she can go out of sight of the supervisor to read something or talk to someone, which can lead to fraudulent answers and solutions. Therefore, even if there is no confirmation that the information about the test has been obtained, it will be treated as a fraudulent act. Specifically, when the examinee disappears from the video, it is determined to be "unauthorized departure". That is, a person reflected in the image is detected as an examinee by image analysis, and if the examinee who has been detected up to that point is no longer detected, it is determined to be "unauthorized absence".

"Book browsing" will be explained. Books are, for example, textbooks and reference books. One of the aims of the exam is to confirm the acquisition of knowledge in the textbook, so it is a prerequisite to answer by your own knowledge without looking at the textbook. On the contrary, the act of pretending to have acquired knowledge corresponds to cheating. Specifically, when the video contains a book and the examinee's line of sight is directed toward the book, it is determined to be "book browsing". That is, the book reflected in the image is detected by image analysis, the line-of-sight direction of the examinee is detected, and if the line-of-sight is directed to the position of the book, it is determined to be "book browsing". It is also prohibited for the examinee to possess books during the examination. In other words, if the book appears in the video around the examinee, it will be subject to caution.

"Smartphone browsing" will be explained. Smartphones can store arbitrary data and access external information. Therefore, since it is easy to acquire the knowledge required in the test with a smartphone, viewing the smartphone itself is regarded as cheating. Specifically, the smartphone reflected in the image is detected by image analysis, the line-of-sight direction of the examinee is detected, and when the line-of-sight is directed to the smartphone, it is determined to be "smartphone browsing". It is also prohibited to carry a smartphone during the test. If the smartphone is shown in the image around the examinee, it will be subject to caution.

Explain "third party advice". A third party refers to a person other than the examinee and the supervisor, such as a family member, a friend, or a tutor. If you get the knowledge of another person and answer, you do not confirm the knowledge of the person. Therefore, obtaining knowledge and hints from a third party is equivalent to cheating. Specifically, voice recognition recognizes the voice input to the microphone, detects the voice of a person other than the examinee, and the words are related to the exam question or answer (for example, "gravity" or "No. 1"). ", Etc.) is included, it is judged as" advice of a third party ".

In addition to these fraudulent acts, possession of prescribed items is prohibited. For example, possession of "books" and "smartphones" is prohibited. The predetermined article is detected by image recognition. Furthermore, the presence of "third parties" is prohibited. Third parties are also detected by image recognition. A person who has different facial characteristics from the examinee, a person who has different body shape characteristics from the examinee, and a person who has different clothes characteristics from the examinee are judged to be a third party.

It also detects suspicious acts that are suspected of being fraudulent. For example, when the sound of turning paper is detected by voice recognition, it is determined that the act is suspicious because the page of the book may be turned. When the line of sight of the examinee deviates from the screen of the examinee terminal 100 and detects a movement of reciprocating left and right by image recognition, it is determined that the act is suspicious because it may be reading a sentence. In addition, if it is determined by image recognition that the examinee's line of sight deviates from the screen of the examinee terminal 100 and stays in the same place for a predetermined time or longer, it is determined that the examinee is suspicious because he / she may be looking at a smartphone or a memo. do.

The horizontal and back directions of the notebook computer are not taken by the built-in WEB camera. Therefore, books placed next to or behind a laptop computer cannot be detected. Therefore, the reflection image of the pupil of the examinee may be analyzed to detect an article or a person in the lateral direction or the back direction of the notebook computer. Specifically, a reflected image is extracted from the image of the examinee's pupil, and image recognition is performed on the reflected image. If a "book" or "smartphone" is detected from the reflected image of the examinee's eyes, it corresponds to possession of prohibited items. It also corresponds to fraudulent acts such as "book browsing" and "smart browsing". If a third party is detected in the reflected image of the examinee's eyes, it is also subject to caution.

As described above, when a prohibited item, fraudulent activity, suspicious activity or a third party is detected, a notification urging the supervisor to be alert is sent to the supervisor terminal 300. The supervisor terminal 300 outputs the content of the alert by voice or display. For example, a notification of the message "The first examinee has detected a smartphone that is prohibited from possession. Please be careful." Is sent, and the supervisor terminal 300 outputs this message by voice or screens. Display on. In addition, the video and audio of the examinee to be watched are also sent to the supervisor terminal 300. The image of the examinee to be watched is enlarged and displayed on the supervisor terminal 300. This screen is called the examinee enlargement screen. The examinee enlargement screen will be described later in relation to FIG. 3 (B). On the examinee's enlarged screen, it is possible to play back the video and audio that were the source of detection of prohibited items. It is also possible for the supervisor and the examinee to make a call with video.

In the event of a toilet or poor physical condition, the examinee may leave the seat with the permission of the supervisor. Candidates may also ask the supervisor if they have any questions about the exam questions or answer columns. In order to deal with such a case, the online test server 200 also detects a call from the examinee to the supervisor. For example, if a predetermined word such as "I'm sorry", "teacher" or "I have a question" is recognized by voice recognition, it is determined that the supervisor has been called. In addition, the image recognition raises the examinee's hand, determines that the examinee's line of sight is facing the examinee terminal 100, and makes some voice (for example, "that" or "yes"). Is detected, it is determined that the supervisor has been called.

When the act of calling from the examinee to the supervisor is detected, the video and audio of the called examiner are sent to the supervisor terminal 300. The image of the test taker who called is enlarged and displayed as a test taker enlarged screen on the supervisor terminal 300. In addition, the supervisor and the examinee can make a call with a video.

FIG. 3A is a screen view showing an example of the supervision screen 310.
The supervisor terminal 300 includes a browser. The browser of the supervisor terminal 300 displays the supervisor screen 310, which is a WEB page. The supervision screen 310 is provided with a display area for each examinee (hereinafter referred to as “examinee display area 312”), and the video received from each examinee terminal 100 is expanded in each examinee display area 312. In this example, the examinee display area 312 having 4 rows × 5 columns is provided. That is, 20 test takers are taking the test at the same time. The voice of each examinee is also output from the speaker of the supervisor terminal 300 all at once. The supervisor monitors the situation of everyone on the supervisor screen 310.

FIG. 3B is a screen view showing an example of the examinee enlarged screen 320.
For example, when a prohibited item, fraudulent activity, suspicious activity, or a third party is detected and a situation is set in which a certain examinee is warned, the supervisory screen 310 is switched to the examinee enlargement screen 320. The examinee enlargement screen 320 is provided with an enlarged display area 322, and the image received from the examinee terminal 100 of the examinee to be watched is enlarged and displayed.

If the supervisor wants to check the video that is the source of detection such as prohibited items, click the play button 324. Then, the image that is the detection source is enlarged and displayed in the enlarged display area 322. The video that is the detection source is recorded in the online test server 200. If the supervisor determines that there is no problem, he / she clicks the close button 328 to close the examinee enlargement screen 320 and switch to the supervisor screen 310.

If the supervisor wants to hear the test taker or pay attention to the test taker, he / she clicks the call button 326. Then, the examinee and the supervisor can make a call with a video. When the call is finished, the close button 328 is clicked to close the examinee enlargement screen 320 and switch to the supervisory screen 310.

Further, even when a call from a certain examinee is detected, the supervisory screen 310 is switched to the examinee enlargement screen 320. In the enlarged display area 322, the image received from the examinee terminal 100 of the called examinee is enlarged and displayed. When responding to the call, immediately start a video call between the examinee and the supervisor. Therefore, the play button 324 and the call button 326 may be omitted.

The video / audio storage unit 290 stores video and audio in which possession prohibited objects, third parties, fraudulent acts or suspicious acts are detected.

FIG. 5 is a data structure diagram of the examinee master.
The test taker master has a record for each test taker. The record contains the examinee number, the examinee's name, and the examinee's account (login ID and password).

FIG. 6 is a sequence diagram of an online test.
Candidates taking the online test enter the URL for the test taker notified in advance into the browser. Then, the browser of the examinee terminal 100 accesses the URL for the examinee (S10).

When the access reception unit 252 of the online test server 200 receives the access to the URL for the examinee from the examinee terminal 100, the login screen transmission unit 232 transmits the data of the login screen to the examinee terminal 100 (S12). ..

When the examinee terminal 100 receives the data on the login screen, the browser of the examinee terminal 100 displays the login screen (S14). The login screen includes an input area for a login ID and a password. Candidates enter the login ID and password notified in advance. The browser of the examinee terminal 100 accepts the input of the login ID and the password (S16), and sends the input login ID and the password, that is, the account to the online test server 200 (S18).

When the account receiving unit 254 of the online test server 200 receives the login ID and password, the login processing unit 212 executes a login process for authenticating the examinee (S20). If the received login ID and password match any pair of login ID and password registered in the examinee master, the examinee is identified and the authentication succeeds. On the contrary, if none of the login ID and password pairs match, the authentication fails. If authentication fails, the following processing is not performed. If the authentication is successful, the shooting guide screen transmission unit 234 transmits the data on the shooting guide screen to the examinee terminal 100 (S22).

When the examinee terminal 100 receives the data of the photography guide screen, the browser of the examinee terminal 100 displays the photography guide screen (S24). On the shooting guide screen, the content that prompts you to shoot the surroundings by clicking the shooting start button is described. The perimeter is, for example, the surface of the desk, under the desk, around the desk, or above the desk. When the shooting start button is clicked (S26), the built-in camera is activated, shooting is started, and voice is input to the microphone. The browser of the examinee terminal 100 starts shooting and transmits the shot video and audio to the online test server 200 (S28). This shooting and transmission of video and audio will continue until the test is completed. The examinee photographs the surroundings (S30) according to the instructions on the photographing guide screen, and the photographed image is sent to the online test server 200.

The video / audio receiving unit 256 of the online test server 200 continuously receives video and audio from the examinee terminal 100. The monitoring unit 216 checks before the test whether there are any prohibited belongings or a third party based on the video / audio (S32). The monitoring unit 216 recognizes the article, the posture of the examinee, the line of sight of the examinee, and the voice and noise of the person by the AI function. For example, if a book such as a textbook or a reference book, a notebook or a memo, or a prohibited item such as a smartphone or a tablet terminal is shown, it is judged to be inappropriate. It is also judged to be inappropriate when a third party other than the examinee is shown or when the voice of the third party is recognized. If it becomes inappropriate, a warning is notified to the supervisor terminal 300 so that the examinee and the supervisor can talk online. Alternatively, the message transmitting unit 242 may send a message instructing the examinee terminal 100 to remove the prohibited items or a message instructing the exit of a third party.

Move on to the sequence shown in FIG.
The standby screen transmission unit 236 of the online test server 200 transmits the data of the standby screen to the examinee terminal 100 (S34).

When the examinee terminal 100 receives the data on the standby screen, the browser of the examinee terminal 100 displays the standby screen (S36). The standby screen shows the waiting time until the test start time.

At the time when the test starts, the test content distribution unit 238 of the online test server 200 distributes the test content including the image data of the test question 112 and the structured data of the answer column 114 to the test taker terminal 100 of each test taker ( S38). A program that instructs the OS (operating system) so that the browser occupies the entire screen is added to the test content.

When the examinee terminal 100 receives the examination content, the browser of the examinee terminal 100 displays the image of the examination question 112 and the answer column 114 by the examination content (S40). The browser of the examinee terminal 100 further executes a program attached to the test content, and instructs the OS that the browser occupies the entire screen. This spreads the browser across the screen and hides other windows. Therefore, it is possible to prevent cheating due to information browsing using the examinee terminal 100.

The browser of the examinee terminal 100 accepts the answer input to the answer column 114 (S42). The accepted answer is retained as internal data of the browser.

When the test is started, the monitoring unit 216 of the online test server 200 starts the monitoring process for the examinee (S44). In the monitoring process, as described above, prohibited items, fraudulent acts, suspicious acts or third parties are detected.

When the monitoring unit 216 of the online test server 200 detects a prohibited object, a third party, a fraudulent act or a suspicious act, the monitoring unit 216 records the video and audio as the detection source. Specifically, the video / audio storage unit 290 stores the video and audio from a predetermined time (for example, 5 seconds) before the video showing the prohibited object to be captured until the prohibited object disappears.

When the end time is reached, the notification transmission unit 240 of the online test server 200 transmits the end notification to each examinee terminal 100 (S46).

When the examinee terminal 100 receives the end notification, the browser of the examinee terminal 100 transmits the answer data to the online examination server 200 (S48). Then, the browser of the examinee terminal 100 ends the shooting and the video transmission, and finishes the whole process (S50). A program for transmitting answer data to the online test server 200 when the end notification is received is added to the test content, and the browser of the test taker terminal 100 executes this program.

When the answer data receiving unit 258 of the online test server 200 receives the answer data, the answer data storage unit 288 stores the received answer data in association with the examinee number (S52). Then, the monitoring unit 216 ends the monitoring process (S54).

8 and 9 are flowcharts showing a processing process related to supervisor support in the online test server 200.
When the login processing unit 212 receives access to the URL for the supervisor from the supervisor terminal 300, the access reception unit 252 executes a login process for authenticating the supervisor, as in the case of the examinee (S60). ). If the supervisor's authentication fails, no further processing is performed.

If the supervisor authentication is successful, the supervisor screen generation unit 214 generates the supervisor screen 310. Specifically, the video of each examinee sent from the examinee terminal 100 is developed in the examinee display area 312 corresponding to the examinee. Then, the supervisor screen transmission unit 246 transmits the data of the supervisor screen 310 to the supervisor terminal 300 together with the voice transmitted from the examinee terminal 100 (S62). The generation and transmission of the supervision screen 310 are continuously performed. The supervisor screen 310 is displayed on the browser of the supervisor terminal 300, and the voice of each examinee is output from the speaker.
