[Effect of invention]

According to the present invention, it is possible to provide a dart throwing game device capable of displaying a dart throwing speed, a dart throwing speed display method, and a program.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. In addition, in each figure, the thing attached with the same code|symbol has the same or the same structure.

<Overall configuration> FIG. 1 is an external perspective view of the darts game apparatus according to the embodiment. As shown in FIG. 1, the dart game apparatus 10 is formed in, for example, a vertical rectangular parallelepiped shape. The darts game apparatus 10 provides players with a darts game in which, for example, one player throws three darts continuously in one round or the like. The dart can be a soft dart, a hard dart, or the like, and is not particularly limited.

The dart game device 10 includes a dart board 12 and a display device 14 . The dart board 12 is arranged at an approximate line-of-sight position in the player's standing posture on the front side of the dart game apparatus 10 . The display device 14 displays still images or moving images.

In addition, on the front surface of the dart game apparatus 10, a coin slot, a mode selection switch, and the like are provided. The player puts the fee into the coin slot, presses the mode selection switch, selects the game mode, and plays the darts game. In this dart throwing game, the player stands at a specific position in front of the dart throwing game device 10 and throws darts by aiming at a specific target of the dart board 12 . The front end of the dart reaching the dart board 12 pierces the dart board 12, the coordinate position of the dart pierced is detected, and the score is displayed on the display device 14 according to the pierced position.

FIG. 2 is a front view of the dart board 12 . The speed sensor 16 is installed on the upper left of the dart board 12, measures the speed of the surrounding objects, and outputs speed data indicating the speed of the measured objects. Furthermore, the installation position of the speed sensor 16 is not limited to the position shown in FIG. 2 . Can be installed in any position, as long as the dart speed can be measured.

The disk surface 18 is divided into a plurality of sections with different scores, and a section sensor for detecting which section of the plurality of sections is pressed is installed on the back of the disk surface 18 . The segment sensor is composed of a switch group set for each segment. By pressing the switch corresponding to the segment with the force applied when the dart pierces the segment, the specific dart pierces the segment by pressing the switch corresponding to the segment. section.

On the back of the dart board 12, an impact sensor for detecting the impact applied to the dart board 12 is installed. The impact sensor is used to detect, for example, where on the entire dartboard 12 a dart hits. In the segment sensor, only when the dart hits the disk surface 18 can the dart hit be detected, but if it is an impact sensor, even when the dart hits a position that deviates from the disk surface 18, it will not be detected. Able to detect being hit by a dart.

Furthermore, the dart throwing game device 10 may also be provided with a position detection sensor (it is not required to be provided, and the same is true in the following description), and the position detection sensor includes: a plurality of light sources 24A, which are installed on the dart board The periphery of 12; a plurality of light sensors 24B, which detect the light intensity of the light emitted from the light source 24A; and a processing device, which calculates the position of the disk surface 18 where the dart was pierced based on the light intensity. By having the position detection sensor, the dart game apparatus 10 can determine the position at which the dart pierces the board surface 18 with a more detailed accuracy than the segment unit.

<Hardware Configuration> FIG. 3 is a diagram showing an example of the hardware configuration of the dart game apparatus 10 . The dart game device 10 includes a display device 14 , a speed sensor 16 , an impact sensor 20 , a segment sensor 22 , a light source 24A, a light sensor 24B, an operating device 26 , and a control device 30 . The control device 30 includes a CPU (Central Processing Unit) 32 and a memory 34 that control the entire system.

When the power of the dart game device 10 is turned on, the CPU 32 reads the game program according to the startup program stored in the memory 34 , and outputs the game screen to the display device 14 . In addition, the game mode desired by the player is performed by an input signal from the operation device 26 for inserting coins, an input signal from a selection switch, a game start switch, and the like.

<Configuration of functional block> FIG. 4 is a diagram showing an example of the configuration of a functional block of the dart game apparatus 10 . The dart game device 10 includes a game execution unit 100 , a speed detection unit 102 , a display unit 104 , and a violation detection unit 106 . The game execution unit 100 , the speed detection unit 102 , the display unit 104 , and the violation detection unit 106 can be realized by processing the CPU 32 to execute a program stored in the memory 34 . Also, the program can be stored in a recording medium. The recording medium on which the program is stored may be a non-transitory recording medium readable by a computer. The non-transitory recording medium is not particularly limited. For example, it can be a recording medium such as a USB (Universal Serial Bus) memory and a CD-ROM (Compact Disc-Read Only Memory).

The game execution unit 100 has a function of performing various processes for executing a dart game. Various processes include, for example, performing the game mode selected by the player, determining that the dart hits the dart board 12, determining the position where the dart pierces the board 18, calculating the score, and displaying an animation for playing the dart game.

In addition, the game execution unit 100 determines the time when the impact sensor 20 detects the impact as the time when the dart hits the dart board 12 . In addition, the game execution unit 100 may detect the time point when any one of the plurality of segments included in the dart board 12 is pressed by the segment sensor 22 regardless of whether the impact sensor 20 detects an impact, or From the time when the position detection sensor receives the notification that the dart has penetrated the board surface 18 , it is determined as the time when the dart hits the dart board 12 . When it is determined that the dart hit the dart board 12, the game execution unit 100 notifies the speed detection unit 102 that it has been determined that the dart hit the dart board 12.

The speed detection unit 102 has a function of detecting the speed of the dart thrown by the player at the dart board 12 using the speed data indicating the speed of the object output from the speed sensor 16 . Here, the speed sensor 16 of the present darts game device 10 may also be a sensor that discretely outputs speed data representing the speed of the object detected by the speed sensor 16 . In this case, the speed detection unit 102 may also set the period from the time when the game execution unit 100 determines that the dart hits the dart board 12 to the time point earlier than the time by a certain time (hereinafter referred to as “specific determination” Period") The speed data received from the speed sensor 16 is detected as the throwing speed.

The display unit 104 has a function of displaying the dart throwing speed detected by the speed detection unit 102 on the display device 14 .

The violation detection unit 106 has a function of determining whether or not the player has committed an illegal act. Specifically, when the game execution unit 100 determines that the dart pierces the board surface 18 and the speed detection unit 102 detects the speed of the dart throw, the violation detection unit 106 determines that the player has not committed an illegal act. In addition, when the game execution unit 100 determines that the dart pierces the board surface 18 and the speed detection unit 102 does not detect the speed of the dart throw, the violation detection unit 106 determines that the player may have committed an illegal act. The illegal behavior by the player is due to the player pressing the segment by himself, although he does not actually throw a dart, but it seems to be throwing a dart, thus causing the misjudgment of the dart game device 10 . It may be set that the game execution unit 100 does not count points when the violation detection unit 106 determines that the player may have committed an illegal act. In addition, when the violation detection unit 106 determines that the number of times the player may have committed an illegal act exceeds a predetermined number of times, the game execution unit 100 may determine that the player has committed an illegal act without counting points.

<Processing Procedure> (About dart throwing speed detection) Next, the concrete processing procedure performed by the dart throwing game apparatus 10 is demonstrated. The speed sensor 16 in the present embodiment is, for example, a Doppler sensor, which is installed on the dart board 12 in a manner of emitting microwaves to the space between the player and the dart throwing game device 10 . The speed sensor 16 detects the speed of the object by using the difference between the frequency of the emitted microwave and the frequency of the microwave reflected by the moving object.

FIG. 5 is a diagram for explaining the processing sequence of detecting the dart throwing speed. As shown in FIG. 5 , the speed sensor 16 discretely outputs speed data representing the speed of the object. The vertical direction of FIG. 5 represents the speed (km/h), and the horizontal direction represents the time (t). P1 to P6 in FIG. 5 are arranged in order of time when the speed detection unit 102 receives the speed data output from the speed sensor 16 .

Here, since the speed sensor 16 cannot determine whether the moving object is a dart throw, the speed data output from the speed sensor 16 not only includes the speed of the dart throw, but also includes the speed detected according to the player's waving of the wrist. data, or velocity data detected by microwaves being reflected by people walking around the darts game apparatus 10 .

Therefore, in order to properly select the speed data corresponding to the dart throwing speed from the speed data received from the speed sensor 16, the speed detection unit 102 may also determine the following speed data as the speed data corresponding to the dart throwing speed: , in the more than one speed data received from the speed sensor 16 during a specific determination period, at the time point closest to the time point when it is determined that the dart hits the dart board 12, the speed sensor 16 receives the data speed data.

Here, the so-called specific determination period refers to the time from the time when the game execution unit 100 determines that the dart hit the dart board 12 (T1 in FIG. 5 ) until a specific time (for example, 1 second or 0.5) has elapsed from the time point. seconds, etc.) between the time points (T2 in Figure 5). Therefore, the speed detection unit 102 determines the measurement data measured when the dart is about to hit the dart board 12 as the speed data corresponding to the speed of the dart throwing, so that it is possible to suppress false detection of the speed based on the player's waving of the wrist. The speed data that is not related to the dart-throwing speed, such as the data, is determined as the speed data corresponding to the dart-throwing speed, so that the dart-throwing speed can be detected with higher accuracy.

In addition, the speed sensor 16 can also determine the speed data with the fastest speed in a specific determination period as the speed data corresponding to the dart throwing speed. In a store where the dart-throwing game device 10 is placed, it is considered that there is generally no object that moves faster than the flying speed of the dart-throwing device, so that it can be suppressed that the speed data corresponding to the object other than the dart-throwing object is erroneously judged as the dart-throwing object. The speed data corresponding to the dart speed, so that the dart speed can be detected with higher accuracy.

Here, it is assumed that the speed data output from the speed sensor 16 does not reach the speed detection unit 102 within a specific determination period due to some factors, so that the speed detection unit 102 cannot detect the dart throwing speed. In order to cope with such a situation, the speed detection unit 102 may also determine that the dart hits the dartboard 12 after the time when the speed detection unit 102 does not receive the speed data from the speed sensor 16 within a specific determination period. The speed data received from the speed sensor 16 is determined as the speed data corresponding to the throwing speed. More specifically, when the speed detection unit 102 does not have the speed data received from the speed sensor 16 within a specific determination period, it can also be determined at the time when the dart hits the dartboard 12 ( The speed data received from the speed sensor 16 during the period from T1) in FIG. 5 to a time point (T3 in FIG. 5) after a specific time has elapsed is determined as the speed data corresponding to the dart throwing speed. Even if the speed data output from the speed sensor 16 is delayed due to some factors and does not reach the speed detection part 102, the speed detection part 102 can still detect the dart throwing speed.

(Correction of dart throwing speed) The speed sensor 16 detects the dart throwing speed using the Doppler effect. Here, in the case of using the Doppler effect to detect the velocity, if the microwave emission direction and the moving direction of the object to be detected are not on the same axis, the object velocity will be detected as low, resulting in a measurement error.

Fig. 6 is a diagram showing an angular difference between the microwave emission direction and the moving direction of the dart. A1 represents the position where the player throws the dart, and B1 and B2 represent the position where the dart pierces the board surface 18 . The track O1 represents an example of the track where the player throws a dart from the position of A1 and pierces into B1, and the track O2 represents an example of the track where the player throws a dart from the position of A1 and pierces into B2. In addition, L1 represents an example of the estimated position where the microwave emitted from the speed sensor 16 collides with the dart and is reflected. When the dart is flying along the track O1, the angle difference between the traveling direction of the microwave and the moving direction of the dart is set as θ ₁ , and when the dart is flying along the track O2, the angle between the traveling direction of the microwave and the moving direction of the dart is set as θ 1 . The difference is set to θ ₂ . In the case of FIG. 6 , since θ ₁ <θ ₂ , the measurement error of the dart-throwing velocity becomes larger when the dart flies along the track O2 than when the dart flies along the track O1.

Here, the dart-throwing trajectory from when the dart is thrown until the dart pierces the board surface 18 varies according to the position where the player throws the dart, the dart-throwing speed, and the position where the dart pierces the board surface 18 . However, if the position where the player throws the dart is fixed, the trajectory of the dart can be estimated based on the speed of the dart and the position where the dart pierces the board surface 18 . In addition, the angle formed by the direction of the microwave emission and the direction of the movement of the dart to be detected can be estimated by preliminarily setting the position estimated to be the reflection of the microwave on the trajectory of the dart to be fixed.

Therefore, in this embodiment, in order to simplify the process of correcting the dart throwing speed, the position where the player throws the dart (A1 in FIG. 6 ) and the position where the dart collides with the microwave can also be estimated (L1 in FIG. 6 ) ) is set to fixed. In this state, the speed detection unit 102 can also calculate the speed based on the speed data determined as the speed data corresponding to the dart throwing speed from the speed data received from the speed sensor 16 and the position where the dart pierces the disk surface 18 . The angle difference between the traveling direction of the microwave and the moving direction of the dart throw is used to correct the value of the speed data by using the calculated angle difference, so as to detect the corrected dart throw speed. Furthermore, when the segment sensor 22 detects the position where the dart pierces the disk surface 18, the speed detection unit 102 can also regard the position where the dart pierces the disk surface 18 as the center of the segment. In addition, when detecting the position where the dart pierces the disk surface 18 by the position detection sensor, the speed detection unit 102 can also set the position detected by the position detection sensor itself as the position where the dart penetrates the disk surface 18 .

Also, as another method, the dart-throwing speed, the position where the dart-throwing pierces the disk surface 18, and the amount of change in the dart-throwing speed due to the angle difference between the microwave traveling direction and the dart-throwing direction can also be correlated. A table (speed correction table) is stored in the memory 34 or the like in advance. In addition, the speed detection unit 102 can also retrieve the table by using the speed data received from the speed sensor 16 and the position where the dart pierces the disk surface 18 as a key, so as to obtain the variation of the speed of the dart, and use the data as a key. The obtained variation is multiplied by the speed data obtained from the speed sensor 16, thereby detecting the dart throwing speed. In this table, the position where the dart pierces the disk surface 18 is located in the disk surface 18, and can be divided into sections or more detailed units than sections.

(Modification) In this embodiment, instead of the Doppler sensor, a speed sensor using a stereo camera mounted on the dart board 12 may be used as the speed sensor 16 . A speed sensor using a stereo camera, for example, two cameras are used to photograph the darts flying toward the dart board 12, thereby measuring the distance between the dart board 12 and the darts, and based on the movement of the darts obtained from the results of the multiple measurements Distance and travel time to calculate dart throwing speed.

The elements included in the embodiment and their arrangement, materials, conditions, shapes, dimensions, etc. are not limited to those illustrated, and can be appropriately changed.

In addition, the function of one "part" or device may be realized by two or more physical mechanisms or devices, and the function of two or more "parts" or devices may be realized by one physical mechanism or device.
