Description

  The present invention relates to a “time trial” for competing for time required for answering a quiz problem or clearing a predetermined face of a game in an event or game.

  Currently, services such as events and games in which a plurality of users participate via a network are provided. In an event or game, a “time trial” is often performed to compete for time required for answering a quiz problem or clearing a predetermined face of the game. Participating users expect this time trial to be performed fairly.

  On the other hand, in the case of via a network, the communication time enters before and after the time when the “time trial” is desired. For this reason, an unfair impression is given to the user. The prizes obtained by the “time trial” winners are provided by the user paying a participation fee or sponsored by the sponsor. Therefore, it is required that more users participate by making a fair decision.

  To deal with this communication time problem, for example, in Patent Document 1, a prize program is incorporated in a prize drawing information, a timer program is incorporated into the prize information, the answer time is counted at the user's terminal, and the answer time is compared to determine the winning. Depending on the communication time, time trials were conducted.

  However, in the time trial method as described above, the user may change the clock of the terminal. For this reason, the user cannot hesitate the impression that fraud is performed and hesitates to participate.

On the other hand, it is conceivable to perform a time trial with fairness by making a determination after considering the communication time on the server, but it is necessary to prepare a communication means that guarantees a certain communication quality. For example, the threshold is high for the user. This is also a problem for managers who want many users to participate.

  Since the counter check program operates on the client terminal, the time required for communication via the network is not included in the input time, and the user can participate without worrying about the difference in the communication environment.

Embodiment 2. FIG.
In the first embodiment described above, the counter check program is transmitted from the server and executed by the client terminal, thereby making it difficult to modify the counter. On the other hand, the second embodiment is an embodiment in which the server checks the counter of the client terminal using communication when the server and the client terminal can periodically communicate during the period from participation to result determination. It is. The system configuration of the embodiment is the same as that of the first embodiment shown in FIG.

FIG. 5 shows the operation of the server and the client terminal in such a case. S1-S6 are the same as FIG. 4 which shows operation | movement of Embodiment 1. FIG. FIG. 5 is characterized by a loop portion surrounded by a broken line.

(2) Further, the server 1 periodically transmits a counter check request (counter value acquisition request) to the participating client terminal 2A until a time trial result is obtained (enclosed by a broken line in FIG. 5). Loop part).

(3) Upon receiving the counter check request (S204), the client terminal 2A acquires the counter value by the counter check program (S205), and transmits the counter value to the server 1 (S206).

  When the server 1 receives the counter value (response counter value) (S208), the client counter check unit 12 refers to the counter information DB to determine whether the counter value (response counter value) is an expected value (S209). . If this determination fails, or if no response is received for a predetermined time in response to the counter check request, the participation qualification of the client terminal is deleted.

  As described above, by checking the counter value at the server other than at the start of input and at the end of input, the trouble of counter modification is complicated and it is difficult to perform fraud.

Embodiment 3 FIG.
In the above embodiment, the counter provided in the client terminal is used, but the third embodiment is an embodiment in which the client terminal uses an external counter. The system configuration of the third embodiment is the same as the configuration of the first embodiment shown in FIG.

  FIG. 6 is a configuration diagram of a client terminal in such an embodiment.

  In FIG. 6, a client terminal 4 is a terminal used by a user participating in a time trial. The count device 5 is a device for connecting to the client terminal 4 and acquiring a count value. FIG. 7 shows an example of the appearance of the client terminal 4. In FIG. 7, a mobile phone 55 is shown as an example of the client terminal 4. In FIG. 7, the counting device 5 connected to the mobile phone 55 has a card shape.

  The counting device 5 includes a counter 51, a correction recording memory 52 (change history storage unit) that holds a change record of the counter value from the outside, a counter value input / output unit 53 that corrects the counter value and acquires the counter value, Is provided. When the counter value is corrected from the outside, the counter value input / output unit 53 corrects the counter 51 and rewrites the content of the correction recording memory 52 to a value different from that before correction.

  Next, the operation will be described with reference to FIG. Compared to FIG. 4 showing the first embodiment, S304, S308, S314, and S317 in FIG. 8 are characteristic.

  Similarly to the first embodiment, the client terminal 4 receives the counter check program from the server 1 (S302), and acquires the “counter type” and the “counter value” from the counting device 5 using the counter check program (S302). ). Further, the client terminal 4 acquires a counter correction record from the counting device 5 (S304), and transmits it to the server 1 together with the counter type and the counter value (S305).

  Receiving this information (S306), the server 1 determines participation qualification (S307) and holds the counter value and the counter correction record (S308). S309 to S312 are the same as S7 to S11 of FIG.

  When the client terminal 4 obtains the counter value at the end of input (S313), the client terminal 4 obtains a counter correction record from the counting device 5 (S314), and the server 1 together with the answer data, the input start counter value, and the input end counter value. (S315).

  When the server 1 receives the answer data (S316), it confirms the counter correction record (S317), and confirms that there is no change from the time when the participation determination is made. Thereafter, it is determined whether or not the answer data is correct, and the counter value at the start of input and the counter value at the end of input are held (S318) (S318 to S323 are the same as in FIG. 2).

  As described above, when the counter value is corrected, the counter value is corrected during the time trial period by acquiring the counter value by using a counting device having a correction recording memory that rewrites the value before the correction. It is difficult to provide the user with fairness. In the third embodiment, it is not always necessary to communicate during the period from the determination of participation qualification to the end of input, which also leads to easier participation of more users.

  In addition, it is easy to improve the reliability of the counter value by creating the counting device 5 of the third embodiment as a device that takes time and effort for disassembly, or by protecting the contents of the correction recording memory 52.

Embodiment 4 FIG.
In the above embodiment, the client terminal can display the user input screen immediately after receiving the “input data”. However, for example, when solving a puzzle, after a user solves a puzzle at a client terminal, the user participates from another client terminal, and fraud is performed as if the user was able to answer in a short time. There is. As one means for preventing this, an embodiment in which user input can be performed at the same time in any client terminal (an embodiment in which no user can input until a certain time) will be described. The configuration of the fourth embodiment is the same as that of the first embodiment shown in FIG.

  FIG. 9 is a configuration diagram of a server in such an embodiment. In addition to the configuration of the server 1 shown in FIG. 1, a newly opened counter value determining unit 65 (specific counter value determining unit) is added.
