The electronic dart board 100 may include a dart plate 200 and a dart pin (not shown) for providing a first dart game mode. Here, the first dart game mode is a general dart game mode, and when the user actually throws the dart pin toward the dart plate 200, the score may be calculated according to the position where the dart pin is inserted into the dart plate 200.

The electronic dart board 100 may further include a display 210 on which the virtual dart board 200 is output to provide a second dart game mode. Here, the virtual dartboard may be an image or image identical to or similar to the actual dartboard 200 output on the display 210. The size and location of the virtual dartboard may change based on the difficulty of the dart game, the user's rating, and the user's age.

The present invention provides a first dart game mode and a second dart game mode at the same time, so that users of various ages can utilize the dart game for various purposes (eg, play, therapy, exercise, etc.).

As will be described later, the display 210 may further output a first score calculated in the first dart game mode and a second score calculated in the second dart game mode.

In the second dart game mode, the electronic dart board 100 recognizes the motion of the user throwing the dart through a sensor provided on the dart plate 200, and displays whether the dart is hit and the score even if the user does not actually throw the dart pin. It may be a method of displaying at (210).

Specifically, in the second dart game mode, when a user holds the mobile terminal 110 functioning as a virtual dart, presses a specific button of the mobile terminal 110 or performs an operation of throwing a dart pin while pressing a specific button, The electronic dart board 100 may recognize a user's motion and output an image and a score on which the virtual dart pin is inserted into the virtual dart board on the display 210.

The electronic dart board 100 may help train children and the elderly who require education and rehabilitation through darts, and beginner users starting a dart game.

The electronic dart board 100 may further include a motion detection sensor 220 that detects a user's motion in the second dart game mode. Here, the motion detection sensor 220 may be an infrared sensor for obtaining distance data.

Specifically, the motion detection sensor 220 may measure the position and distance of the hand using triangulation and a time delay measurement method.

Specifically, the time-of-flight method is a method of restoring distance information by measuring the return time after shooting a specific light wave, and measuring the return time of the laser pulse with a digital count or measuring the return time of the received pulse. A method of measuring time using the phase difference can be used. In this case, in order to create different phase differences, a method of adjusting an exposure section in one pixel or designating a different section time in an adjacent pixel can be applied.

The electronic dart board 100 calculates a first score based on the position where the dart pin is inserted in the dart board 200 in the first dart game mode, and calculates a second score based on the user's motion in the second dart game mode. It may further include a control unit 230 for calculating.

The electronic dart board 100 includes a standard posture including at least one of a user's position, hand motion, hand position, and hand speed, and a database 240 that stores a score table including a plurality of scores according to similarity with the standard posture. It may further include.

For a moment, referring to FIG. 4, the score table shows, for example, 100 points when the user's motion has a similarity of 90% to 100% with a standard posture, 90 points and 0% to 10% when the user's motion is between 90% and 90%. If it is, it may be 0 points.

Referring back to FIGS. 1 to 3, the controller 230 may extract at least one of a user's position, a hand motion, a hand position, and a hand speed from the user's motion in the second dart game mode.

The controller 230 may derive a degree of similarity between the user's posture and the standard posture based on at least one of the extracted user's position, hand motion, hand position, and hand speed.

The control unit 230 may adjust a criterion of a degree of similarity to a standard posture based on, for example, the difficulty level of the dart game, the user's grade, and the user's age.

For example, when the difficulty of the dart game is high, the control unit 230 may increase the standard of similarity, and if the difficulty of the dart game is low, the standard of similarity may be lowered. For another example, when the user is younger, the controller 230 may increase the similarity criterion, and when the user is older, the similarity criterion may be lowered.

The controller 230 may derive a score corresponding to the similarity derived from the score table as the second score. The controller 230 may adjust a score according to the similarity level described in the score table based on, for example, the difficulty level of the dart game, the user's grade, and the user's age.

For example, if the user's grade is high, the control unit 230 may lower the score according to the similarity, and if the user's grade is low, the control unit 230 may increase the score according to the similarity.

According to an embodiment, the controller 230 may derive a score by inputting at least one of the extracted user's position, hand motion, hand position, and hand speed into a pre-learned artificial intelligence model, for example.

Here, the artificial intelligence model minimizes the difference between the score derived by inputting the motion according to at least one of the user's position, hand motion, hand position, and hand speed, and the actual dart score when the actual dart pin is thrown with the corresponding motion. It may be learned to do.

The mobile terminal 110 has a shape that is easy for a user to grasp and functions as a virtual dart. For example, when the user holds the mobile terminal 110 and throws a dart pin, the electronic dart board 100 may recognize the user's motion. In this case, the display 210 may provide an effect similar to that of a real dart game by outputting an image in which the virtual dart pin is inserted into the virtual dart board.

The mobile terminal 110 may include at least one button for receiving a user's input. The mobile terminal 110 may transmit a start command for initiating the second dart game mode to the controller 230 based on a user's input through at least one button.

In this case, after receiving the start command, the controller 230 may start the second dart game mode.

The game server 120 may manage at least one of a dart game including a first dart game mode and a second dart game mode, information of a plurality of users, a community related to a dart game, and a ranking of a plurality of users.

Although not shown, the motion recognition-based smart electronic dart system may further include a media server that provides and manages promotional images and real-time broadcasting.

The gesture recognition-based smart electronic dart system may further include an EMG sensor (not shown) attached to the user's body and transmitting the user's EMG signal to the controller 230.

The control unit 230 transmits the user's EMG signal to the game server 120 in the second dart game mode, and the game server 120 derives an electrical waveform based on the user’s EMG signal at the end of the second dart game mode. I can.
