[0051] When the distance between the cheating detection device 13 and the coil 23 of the examinee P1 is equal to or less than a predetermined distance and a magnetic field is formed by the coil 23, a current flows through the coil 37 due to the magnetic field. On the other hand, when the coil 37 is connected to the power supply 22 and a current flows through the coil 37, a magnetic field is formed around the coil 37.

[0055] (Example of test taker device usage) Assume that examinee P1 enters an examination hall with earphones 24 inserted into his ears, coil 23 attached to his body, and examinee terminal 11 in his possession. When examinee P1 photographs the examination questions with camera 40, the image is stored in auxiliary storage device 18 by processor 16. When examinee P1 inputs the examination questions into microphone 41, the audio is also stored in auxiliary storage device 18 by processor 16. Examinee P1 may transmit the image and audio from examinee terminal 11 to helper terminal 12 by operating operation device 19.

[0056] The helper terminal 12 is operated by a helper who helps the examinee P1. The helper may create answers to the test questions obtained from the examinee terminal 11 and send the answers from the helper terminal 12 to the examinee terminal 11. The answers to the test questions may include image and sound information. When the examinee terminal 11 obtains the answers from the helper terminal 12, it stores the answers in the auxiliary storage device 18. The examinee P1 may operate the operation device 19 to display the images included in the answers on the display device 20.

[0057] The examinee P1 may also operate the operating device 19 to output sound information contained in the answer from the earphone 24. The processor 16 then controls the electric circuit connected to the power source 22 to supply power to the coil 23. When a current flows through the coil 23, a magnetic field is formed around the coil 23, causing the permanent magnet 24A of the earphone 24 to vibrate in accordance with the strength of the magnetic field. As a result, the examinee P1 can hear the sound information output from the earphone 24 through his or her skull.

[0058] (Example of use of fraud detection device) 4 shows an example of how the cheating detection device 13 is used. In step S10, the cheating detection device 13 may determine whether the distance between the cheating detection device 13 and the examinee P1 at the examination site A1 is equal to or less than a predetermined distance. The predetermined distance is a threshold value stored in the auxiliary storage device 28, and corresponds to, for example, the range of the magnetic field formed by energizing the coil 37. The cheating detection device 13 can make the determination in step S10 based on the current position of the cheating detection device 13 at the examination site A1 and the position of the seat 51 of the examinee P1.

[0059] The current location of the cheating detection device 13 can be determined based on, for example, the strength of the radio signals received from multiple repeaters 52A, the difference in arrival time of the radio signals from the multiple repeaters 52A to the cheating detection device 13, a floor plan of the testing site A1, etc. The current location of the cheating detection device 13 at the testing site A1, i.e., the current location of the supervisor P2, is its position within the floor plan of the testing site A1.

[0060] If the fraud detection device 13 determines Yes in step S10, it determines in step S11 whether fraud is being committed using the examinee terminal 11, etc. A magnetic field is formed by the coil 23 of the examinee terminal 11, and when the coil 37 enters the area of ​​the magnetic field (electromagnetic induction wave) formed by the coil 23, a current flows through the coil 37 due to the principle of electromagnetic induction. The current sensor 31 detects the current in the electric circuit 38 connected to the coil 37 and outputs a signal, and the voltage sensor 32 detects the voltage of the electric circuit 38 and outputs a signal.

[0061] The fraud detection device 13 may determine "Yes" in step S11 if one or more of the values ​​of the current flowing through the electric circuit 38 or the voltage of the electric circuit 38 exceeds a threshold value stored in the auxiliary storage device 28. If the fraud detection device 13 determines "Yes" in step S11, it may perform a notification process in step S12 to notify the user that fraudulent activity is occurring.

[0062] The notification process performed by the fraud detection device 13 includes a process of displaying on the display device 30 that fraudulent activity is occurring. The notification process performed by the fraud detection device 13 includes a process of turning on or blinking the lamp 33. The notification process performed by the fraud detection device 13 includes a process of outputting sound information from the sound information output device 34.

[0063] Furthermore, in step S12, the cheating detection device 13 may analyze the current flowing through the electric circuit 38 to reproduce sound information, that is, the answer to the test question, and output the sound information from the sound information output device 34.

[0064] Furthermore, if the cheating detection device 13 determines Yes in step S11, it may perform processing to disrupt cheating in step S13. Disrupting cheating may also mean preventing cheating. The processing to disrupt cheating includes supplying power from the power supply 36 to the coil 37 and causing the coil 37 to generate a magnetic field. When the earphone 24 is present within the area of ​​the magnetic field formed by the coil 37, the permanent magnet 24A vibrates. Therefore, even if the permanent magnet 24A vibrates due to the magnetic field formed by the coil 37, sound information of answers to the test questions is not output from the earphone 24. Therefore, sound information of answers to the test questions transmitted from the helper terminal 12 to the examinee terminal 11 can be prevented from being output from the earphone 24.

[0065] Furthermore, in step S13, the fraud detection device 13 may control the power supplied to the coil 37 so that the permanent magnet 24A vibrates suddenly and with a large amplitude. In other words, the sudden vibration of the permanent magnet 24A with a large amplitude will surprise the examinee P1, which will serve as an indirect warning to the examinee P1.

[0066] Furthermore, cheating detection device 13 may make a decision in step S12 or step S13 to identify the name and examinee number of examinee P1 who is committing cheating, based on the current position of cheating detection device 13 in testing site A1 and the distance between cheating detection device 13 and examinee P1. Furthermore, cheating detection device 13 may store the name and examinee number of examinee P1 who is committing cheating in auxiliary storage device 28.

[0067] Furthermore, the cheating detection device 13 may transmit the name and examinee number of the examinee P1 who is committing cheating to the management computer 50. If there are multiple cheating detection devices 13 at the testing site A1, the processor 26 of the management computer 50 may determine the current location of each cheating detection device 13 in real time and store the determination results in the auxiliary storage device 55.

[0068] It should be noted that fraud detection device 13 may execute the process of step S12 and the process of step S13 at the same time. Furthermore, fraud detection device 13 may execute the process of step S12 after executing the process of step S13.

[0069] If the fraud detection device 13 determines No in step S10, it ends the routine of Fig. 4 without performing the processes of steps S11, S12, and S13. On the other hand, if the fraud detection device 13 determines No in step S11, it ends the routine of Fig. 4 without performing the processes of steps S12 and S13. The processing example shown in Fig. 4 is repeatedly executed at predetermined time intervals.

[0070] (Effects of this embodiment) The cheating detection device 13 can detect cheating using the examinee terminal 11 and notify the supervisor P2. The cheating detection device 13 can also hinder cheating using the examinee terminal 11.

[0071] Furthermore, the cheating detection device 13 can employ a routine that proceeds to step S11 if it determines "Yes" in step S10, and proceeds to step S14 if it determines "No" in step S10. This allows the cheating detection device 13 to avoid performing the processes of steps S12 and S13 in an environment where external disturbances occur. This prevents current from flowing through the coil 37 due to external disturbances. In other words, it prevents power from the power supply 36 from being inadvertently supplied to the coil 37 in a situation where it cannot be determined whether or not cheating is occurring using the examinee terminal 11, etc.
