Description

  The present invention relates to a mobile body system and a program for the mobile body system, and more particularly to a mobile body system and a program for the mobile body system for performing a practice of riding on the mobile body as if it were a game.

  A skateboard is a sporting equipment with wheels attached to a board on which a player rides, and it can easily slide on the road surface, so it is especially popular among young people. Skateboard players are not interesting just by sliding, so they play while listening to music with headphones stereo, or playing slalom with obstacles arranged at equal intervals.

  In order to be able to get on a skateboard, it is necessary to practice various techniques, such as a slalom that slides while avoiding obstacles, and a switch that switches the direction of travel in the reverse direction.

  However, whether the player has successfully slid or not can only be evaluated by the player himself / herself or the other person can see where he is sliding. Therefore, it was difficult to improve by practice alone, and there was no fun.

  Also, to play slalom, you had to actually prepare obstacles, and you had to secure a large space necessary to line them up.

  Japanese Laid-Open Patent Publication No. 9-234289 (Patent Document 1) discloses an automobile game apparatus installed in an amusement park or the like. In this device, a player rides in a small car for play and competes to travel along a prescribed route while hitting the car. A light source is embedded in the road surface, light from the light source is detected by a sensor attached to the lower surface of the automobile, and the number of times is counted.

  However, in this apparatus, since the light source is embedded in the road surface, the automobile can run only on a dedicated course. Moreover, since it is difficult to change the position of the light source, it is easy to get bored.

  Japanese Laid-Open Patent Publication No. 2002-95856 (Patent Document 2) discloses a game system such as orienteering using a real motorcycle. In this system, a predetermined point is assigned to an area that actually exists, and when the motorcycle enters the area, the predetermined point is added or subtracted.

  However, in this system, the area is limited to what is actually present, and it is only a common thing to compete for scores, so it is also not interesting.

In addition, this applicant has proposed the skateboard which changes music according to an external condition in Japanese Patent Application No. 2004-15201 (related application 1). Further, the present applicant has proposed a skateboard that changes music in accordance with the exercise state in Japanese Patent Application No. 2004-15202 (Related Application 2). Furthermore, the present applicant has proposed a skateboard in which a pair of speakers are attached to a board in Japanese Patent Application No. 2004-15203 (Related Application 3).

  An object of the present invention is to provide a moving body system and a moving body system program capable of making a practice of riding on a moving body like a game.

Means for Solving the Problems and Effects of the Invention

  The mobile system according to the present invention includes motion detection means, motion check means, and result presentation means. The motion detection means detects the motion of the movable body that can be steered according to the weight shift of the player. The movement check means checks whether or not the moving body has moved in a predetermined manner based on the movement of the moving body detected by the movement detecting means. The result presenting means presents the check result from the movement checking means to the player. Here, the moving body can be steered according to the player's weight shift, and includes, for example, a skateboard, a snowboard, a kickboard, skiing, a Segway (registered trademark), and a motorcycle. The movement detection means detects the movement of the moving body based on, for example, the steering angle and speed of the moving body, the player's load on the moving body, and the like. The movement check means determines, for example, whether or not the moving body is bent in order from left to right, or determines whether or not the moving direction of the moving body is reversed. The check result may be perceived by the player using auditory information such as a success sound, a failure sound, and voice, or may be perceived by the player using visual information such as a screen display.

  According to this moving body system, the movement of the moving body is detected, and based on this, it is checked whether or not the moving body has moved in a predetermined manner, and the check result is presented to the player. You can practice riding on a moving object as if you were playing a game.

  Preferably, the motion check unit includes a time measuring unit, a time limit unit, and a motion determination unit. The time measuring means measures the elapsed time. The time limiter determines whether or not the elapsed time measured by the timer is within a predetermined time limit. The movement determination means determines whether or not the movement of the moving body detected by the movement detection means is a predetermined movement when the time limit means determines that the elapsed time is within the time limit.

  In this case, the player has to maneuver the moving body to make the prescribed movement within the time limit, so that the player can practice riding on the moving body more effectively.

  Preferably, the movement check unit further includes an elapsed time reset unit that resets the elapsed time measured by the time measuring unit each time the movement determination unit determines that the movement of the moving body is a predetermined movement.

  In this case, since the player has to steer the moving body and repeat the prescribed movement every time limit, the player can practice riding on the moving body more effectively.

  Preferably, the result presentation unit includes a sound signal output unit and a speaker. The sound signal output means outputs a predetermined success sound signal when the movement determining means determines that the movement of the moving body is a predetermined movement, and the time limiting means determines that the elapsed time is not within the time limit. A predetermined failure sound signal is output. The speaker generates sound based on the sound signal output from the sound signal output means.

  In this case, a success sound is generated from the speaker when it is determined that the movement of the moving body is a predetermined movement, and a failure sound is generated from the speaker when it is determined that the elapsed time is not within the time limit. Therefore, the player can recognize by hearing whether the maneuvering of the moving body has succeeded or failed.

  Preferably, the movement check means further includes an evaluation means for setting a predetermined evaluation value according to the number of times that the movement determination means determines that the movement of the moving body is a predetermined movement. The sound signal output means outputs a predetermined evaluation sound signal corresponding to the evaluation value set by the evaluation means.

  In this case, since the evaluation sound is generated from the speaker according to the number of times that the movement of the moving body is determined to be a predetermined movement, the player can recognize the level at which the moving body has been successfully operated.

  Preferably, the motion detection means is attached to the moving body. The mobile system further includes a wireless transmitter, a portable information terminal, and headphones. The wireless transmitter is attached to the moving body and transmits the movement of the moving body detected by the movement detecting means. The portable information terminal is attached to the player. The headphones are connected to the portable information terminal. The movement check means and the result presentation means are included in the portable information terminal. The portable information terminal includes a wireless receiver that receives the movement of the moving body transmitted from the wireless transmitter. The speaker is included in the headphones. Here, the portable information terminal includes, for example, a PDA (Personal Digital Assistance), a portable music player, a cellular phone, and the like. The headphone includes not only a headphone in a narrow sense that is put on the head with a band or the like, but also an earphone that is inserted into or put on both ears.

  In this case, since the movement of the moving body is wirelessly transmitted from the moving body to the portable information terminal, the player can freely operate the moving body by attaching headphones and the portable information terminal to the body.

  A program for a mobile system according to the present invention includes a motion check step for checking whether or not the mobile body has moved in a predetermined manner based on the motion of the mobile body that can be steered in accordance with the weight shift of the player, A computer executes a result presentation step of presenting a check result of the step to the player.

  According to the mobile system program, it is checked whether or not the mobile body has moved in a predetermined manner based on the movement of the mobile body, and the result of the check is presented to the player. You can practice riding as if you were playing a game.

  Preferably, the movement check step includes a step of measuring an elapsed time, a step of determining whether the measured elapsed time is within a predetermined time limit, and the measured elapsed time being determined to be within the time limit. Determining whether or not the movement of the moving body is a predetermined movement.

  In this case, the player has to maneuver the moving body to make the prescribed movement within the time limit, so that the player can practice riding on the moving body more effectively.

  Preferably, the movement check step further includes a step of resetting an elapsed time measured each time it is determined that the movement of the moving body is a predetermined movement.

  In this case, since the player has to steer the moving body and repeat the prescribed movement every time limit, the player can practice riding on the moving body more effectively.

  Preferably, the result presentation step includes a step of outputting a predetermined success sound signal to the speaker when the movement of the moving body is determined to be a predetermined movement, and a determination that the measured elapsed time is not within the time limit. Outputting a predetermined failure sound signal to the speaker.

  In this case, a success sound is generated from the speaker when it is determined that the movement of the moving body is a predetermined movement, and a failure sound is generated from the speaker when it is determined that the elapsed time is not within the time limit. Therefore, the player can recognize by hearing whether the maneuvering of the moving body has succeeded or failed.

  Preferably, the movement check step further includes a step of setting a predetermined evaluation value according to the number of times that the movement of the moving body is determined to be a predetermined movement. The result presentation step further includes a step of outputting a predetermined evaluation sound signal corresponding to the set evaluation value to the speaker.

  In this case, since the evaluation sound is generated from the speaker according to the number of times that the movement of the moving body is determined to be a predetermined movement, the player can recognize the level at which the moving body has been successfully operated.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

  Referring to FIG. 1, a skateboard system 10 according to an embodiment of the present invention includes a skateboard 12, a PDA (Personal Digital Assistance) 14, and stereo headphones 16. The player 18 wears the headphones 16 and rides on the skateboard 12 while listening to music transmitted from the PDA 14.

  Referring to FIG. 2, the skateboard 12 includes an oval board 20 and wheels 22 and 24 attached to the front and rear thereof. The skateboard 12 has a power source and can be self-propelled. Specifically, the motors 26 and 28 are built in the front and rear wheels 22 and 24. When the motors 26 and 28 are driven by the motor drivers 30 and 32, the front and rear wheels 22 and 24 rotate, and the skateboards. 12 is self-propelled. The detailed structure is disclosed in Japanese Patent Application Nos. 2004-15201, 2004-15202, and 2004-15203, the disclosure of which is incorporated herein.

  The skateboard 12 includes a master MCU (Motor Control Unit) 34 that controls the motor 28 in the rear wheel 24, and a slave MCU 36 that controls the motor 26 in the front wheel 22. The master MCU 34 includes a CPU (Central Processing Unit) 38, a motor driver 32 that drives the motor 28 in the rear wheel 24, and a current sensor 40 that detects a current supplied to the motor 28 in the rear wheel 24. The slave MCU 36 includes a CPU 42, a motor driver 30 that drives the motor 26 in the front wheel 22, and a current sensor 44 that detects a current supplied to the motor 26 in the front wheel 22. The slave MCU 36 is connected to the master MCU 34 via a CAN (Controller Area Network) bus 46.

  The skateboard 12 further includes a steering sensor 48 that detects the steering angle of the front wheel 22, a load sensor 50 that detects a load applied to the front wheel 22, a steering sensor 52 that detects the steering angle of the rear wheel 24, and the rear wheel 24. A load sensor 54 for detecting the load. The steering sensors 48 and 52 and the load sensors 50 and 54 are all connected to the master MCU 34, and the master MCU 34 receives the steering angle detected by the steering sensors 48 and 52 and the load detected by the load sensors 50 and 54.

  The skateboard 12 further includes an encoder 56 that detects the number of rotations of the rear wheel 24 and a wireless transmitter 58 that uses short-range wireless communication (such as Bluetooth (registered trademark)). The encoder 56 is also connected to the master MCU 34, and the master MCU 34 receives the rotational speed of the rear wheel 24 detected by the encoder 56, and calculates the speed of the skateboard 12 based on this. The wireless transmitter 58 is also connected to the master MC 34, and the master MCU 34 transmits data signals such as steering angle, load, and speed to the PDA 14 by the wireless transmitter 58. The data signal transmission cycle is, for example, 1 to 100 milliseconds.

  Referring to FIG. 3, the PDA 14 includes a CPU 60, a memory 62 such as a RAM (Random Accesses Memory), a ROM (Read Only Memory), and a hard disk, a wireless receiver 64 paired with a wireless transmitter 58, an LCD ( A display 66 such as a liquid crystal display), a touch panel 68 that receives an input in accordance with the operation of the player, and an audio output circuit 70 are provided.

  The wireless receiver 64 receives data signals such as steering angle, load, and speed transmitted from the wireless transmitter 58. The headphones 16 are connected to a sound output circuit 70 and generate various sounds such as sound, music, and sound effects based on sound signals.

  Next, an operation method and operation of the skateboard system 10 will be described.

  If the skateboard system 10 is used, the slalom shown in FIGS. 4 and 5 and the switch shown in FIG. 6 can be evaluated.

  For example, as shown in FIG. 4, when a player 18 starts a slalom on the skateboard 12 and turns to the left and then turns to the left, a series of movements are repeated several times. And a predetermined success sound is heard from the headphones 16.

  On the other hand, as shown in FIG. 5, when turning right and not turning left within a predetermined time limit, or conversely turning left and turning right within a predetermined time limit, the evaluation score is A predetermined failure sound is heard from the headphones 16 without being given.

  As shown in FIG. 6, when the player 18 is moving forward on the skateboard 12, when the traveling direction is switched to the reverse direction and the back is started, a predetermined evaluation score is given and a predetermined success sound is generated. I hear it from the headphones 16.

  In order to realize such a practice game, a skateboard system program as shown in FIG. 7 is installed in the PDA 14. Specifically, the skateboard system program is recorded in the memory 62, and the CPU 60 executes predetermined information processing according to the skateboard system program.

  Referring to FIG. 7, the PDA 14 first checks whether or not the skateboard 12 has slalomed in a predetermined manner based on the steering angle of the skateboard 12 detected by the steering sensors 48 and 52. (S1), and then a switch check process is performed to check whether or not the traveling direction has been switched to the reverse direction based on the speed of the skateboard 12 detected by the encoder 56 and the master MCU 34 (S2), Next, sound output processing for outputting sound according to the check results is executed (S3). The PDA 14 repeats the slalom check process, the switch check process, and the sound output process every time a predetermined time (for example, 50 milliseconds) elapses after the sound output process ends (S4). Details of the slalom check processing are shown in FIGS. 8A to 8C, details of the switch check processing are shown in FIG. 9, and details of the sound output processing are shown in FIG.

  With reference to FIGS. 8A to 8C, the PDA 14 determines whether or not the step counter is 0 (S101). The step counter counts the number of turns to the right or left, and is first initialized to 0, and then incremented in steps S103, S114, S119, S123, and S128 described later, and in steps S106 and S132 described later. Reset to zero.

  If the step counter is 0 (YES in S101), the PDA 14 determines whether or not the skateboard 12 is turned to the right based on the steering angle of the skateboard 12 received by the wireless receiver 64 (S102). . Here, if the determination as to whether or not the skateboard 12 is bent is made based only on the steering angle, it may be determined that the skateboard 12 is bent even though the skateboard 12 is stopped. Therefore, it is preferable to determine whether or not the skateboard 12 is bent based on the steering angle only when the speed of the skateboard 12 is not zero or is equal to or higher than a predetermined speed.

  If the skateboard 12 is turned to the right (YES in S102), the PDA 14 increments the step counter, that is, counts up from 0 to 1 (S103). Then, the PDA 14 sets a predetermined time limit α in the timer counter (S104), and ends the present slalom check process (S1). The timer counter measures the elapsed time from when the skateboard 12 turns right or left to the left or right, and is set to the time limit α in steps S104, S115, S120, S124, S129, and S133. After that, it is decremented in steps S117, S121, S126, S130, and S135. On the other hand, if the skateboard 12 is not turned to the right (NO in S102), the PDA 14 skips steps S103 and S104 and ends the present slalom check process (S1).

  On the other hand, if the step counter is not 0 (NO in S101), the PDA 14 determines whether or not the timer counter is 0 (S105). When the timer counter is 0 (YES in S105), the PDA 14 resets the step counter to 0 because the player 18 cannot turn right again within the time limit α after the player 18 turns right ( After the failure sound flag is set (S106), the present slalom check process (S1) is terminated. The failure sound flag indicates whether or not a failure sound should be output. The failure sound is a predetermined sound for notifying the player 18 of the failure of the slalom.

  On the other hand, if the timer counter is not 0 (NO in S105), since the time limit α has not yet elapsed since the player 18 turns to the right, the PDA 14 has any one of the step counters 1 to 5. Is determined (S108 to S112).

  If the step counter is 1 (YES in S108), since the player 18 is first turned to the right, the PDA 14 determines whether or not the skateboard 12 is turned to the left (S113). If the skateboard 12 is turned to the left (YES in S113), the PDA 14 increments the step counter, that is, increments from 1 to 2 (S114). The PDA 14 again sets the time limit α in the timer counter (S115) and sets the evaluation sound flag to 1 (S116), and then ends the present slalom check process (S1). The evaluation sound flag indicates an evaluation sound to be output. The evaluation sound is a predetermined sound for informing the player 18 of the number of times of success in a series of movements of turning right and then turning left. In this embodiment, the evaluation sound is output as a success sound. On the other hand, if the skateboard 12 is not turned to the left (NO in S113), the PDA 14 decrements the timer counter, that is, counts down by 1 (S117), and then ends the present slalom check process (S1).

  If the step counter is 2 (YES in S109), the PDA 14 has made a succession of a series of movements in which the player 18 turns right and then turns left, so the PDA 14 checks whether the skateboard 12 is turned right. It is determined whether or not (S118). If the skateboard 12 is turning to the right (YES in S118), the PDA 14 increments the step counter, that is, counts up from 2 to 3 (S119). The PDA 14 again sets the time limit α in the timer counter (S120), and then ends the present slalom check process (S1). On the other hand, if the skateboard 12 is not turned to the right (NO in S118), the PDA 14 decrements the timer counter (S121), and then ends the present slalom check process (S1).

  If the step counter is 3 (YES in S110), the player 18 turns right and then turns right again after making a series of movements such as turning right and then turning left. It is determined whether the vehicle is turning left (S122). When the skateboard 12 is turned to the left (YES in S122), the PDA 14 increments the step counter, that is, counts up from 3 to 4 (S123). The PDA 14 again sets the time limit α in the timer counter (S124) and sets the evaluation sound flag to 2 (S125), and then ends the present slalom check process (S1). On the other hand, if the skateboard 12 is not turned to the left (NO in S122), the PDA 14 decrements the timer counter (S126), and then ends the present slalom check process (S1).

  If the step counter is 4 (YES in S111), the PDA 14 determines whether the skateboard 12 is turned to the right because the player 18 has succeeded twice in a series of movements to the right and then to the left. It is determined whether or not (S127). If the skateboard 12 is turned to the right (YES in S127), the PDA 14 increments the step counter, that is, counts up from 4 to 5 (S128). The PDA 14 again sets the time limit α in the timer counter (S129), and then ends the present slalom check process (S1). On the other hand, if the skateboard 12 is not turned to the right (NO in S127), the PDA 14 decrements the timer counter (S130), and then ends the present slalom check process (S1).

  If the step counter is 5 (YES in S112), the player 18 turns to the right and then turns to the left, and then turns right again, so the PDA 14 It is determined whether or not the vehicle is turning left (S131). If the skateboard 12 is turned to the left (YES in S131), the PDA 14 resets the step counter to 0 (S132). The PDA 14 again sets the time limit α in the timer counter (S133) and sets the evaluation sound flag to 3 (S134), and then ends the present slalom check process (S1). On the other hand, if the skateboard 12 is not turned to the left (NO in S131), the PDA 14 decrements the timer counter (S135), and then ends the present slalom check process (S1).

  After the end of the slalom check process (S2), the PDA 14 starts the switch check process (S2) shown in FIG. Referring to FIG. 9, the PDA 14 determines the current traveling direction of the skateboard 12 based on the speed of the skateboard 12 received by the wireless receiver 64 and the traveling direction when the previous switch check process (S2) was performed. To determine whether the current traveling direction is the same as the previous traveling direction (S201).

  If the current traveling direction is not the same as the previous traveling direction (NO in S201), since the traveling direction of the skateboard 12 has been switched to the reverse direction, the PDA 14 sets a switch sound flag (S202). The switch sound flag indicates whether a switch sound should be output. The switch sound is a predetermined sound for informing the player 18 that the switching of the traveling direction has been successful.

  After setting the switch sound flag, the PDA 14 stores the current traveling direction as the previous traveling direction in the memory 62 (S203), and then ends the switch check process (S2). The saved traveling direction is referred to in step S201.

  On the other hand, if the current traveling direction is the same as the previous traveling direction (YES in S201), the traveling direction of the skateboard 12 is not switched to the reverse direction, so the PDA 14 skips step S202 and proceeds to step S203.

  After the switch check process (S2) ends, the PDA 14 starts the sound output process (S3) shown in FIG. Referring to FIG. 10, the PDA 14 determines whether or not the failure sound flag is set (S301). When the failure sound flag is set (set in S301), since the player 18 has failed in the slalom, the PDA 14 generates a failure sound signal and outputs it to the headphones 16, and the headphones 16 are based on the failure sound signal. A failure sound is generated (S302). The player 18 can recognize that the slalom has failed by listening to the failure sound. On the other hand, when the failure sound flag is not set (reset in S301), the PDA 14 skips step S302.

  After outputting the failure sound (S301) or when the failure sound flag is not set (reset in S301), the PDA 14 determines one of the evaluation sound flags from 1 to 3 (S303 to S305).

  When the evaluation sound flag is 1 (YES in S303), the PDA 14 generates an evaluation sound signal and outputs it to the headphones 16, and the headphones 16 generate an evaluation sound ES1 based on the evaluation sound signal (S306). By listening to the evaluation sound ES1, the player 18 can recognize that a series of movements of turning right and then turning left is successful once.

  If the evaluation sound flag is 2 (YES in S304), the PDA 14 generates another evaluation sound signal and outputs it to the headphone 16, and the headphone 16 generates the evaluation sound ES2 based on this evaluation sound signal ( S307). By listening to the evaluation sound ES2, the player 18 can recognize that the series of movements of turning right and then turning left is successful twice.

  If the evaluation sound flag is 3 (YES in S305), the PDA 14 generates another evaluation sound signal and outputs it to the headphone 16. The headphone 16 generates the evaluation sound ES3 based on this evaluation sound signal. (S308). By listening to the evaluation sound ES3, the player 18 can recognize that a series of movements of turning right and then turning left is successful three times.

  When the evaluation sound flag is not any of 1 to 3, that is, when the evaluation flag remains 0 (default) (NO in S305) or after the evaluation sound is output (S306 to S308), the PDA 14 It is determined whether the sound flag is set (S309).

  When the switch sound flag is set (set in S309), since the player 18 has succeeded in the switch, the PDA 14 generates a switch sound signal and outputs it to the headphone 16, and the headphone 16 is based on this switch sound signal. Switch sound is generated (S310). The player 18 can confirm that the switch has succeeded by listening to the switch sound. After outputting the switch sound signal, the PDA 14 ends this sound output processing (S3).

  On the other hand, when the switch sound flag is not set (reset in S309), the PDA 14 skips step S310 and ends this sound output process (S3).

  As described above, according to this embodiment, the movement of the skateboard 12 is detected, and based on this, whether or not the skateboard 12 has slalomed as determined in advance is checked and switched. It is also checked whether or not. Since the check result is notified to the player 18 by an evaluation sound (success sound) or a failure sound, the player 18 can practice riding on the skateboard 12 as if it were a game.

  In addition, since the player 18 must make a series of movements of maneuvering the skateboard 12 and turning right and then turning left within the time limit, the player 18 can practice riding on the skateboard 12 more effectively. Moreover, since the player 18 has to repeat a series of movements of maneuvering the skateboard 12 and turning right and then turning left every time limit, the player 18 can practice riding on the skateboard 12 more effectively. .

  Also, since the evaluation sound ES1, ES2 or ES3 is generated from the headphones 16 according to the number of times of success in a series of movements of turning right and then turning left, the player 18 succeeds in maneuvering the skateboard 12. Can be recognized.

  In addition, it is not necessary to actually prepare obstacles for practicing slalom, so it is not necessary to secure a large space.

  Also, if music is played back on the PDA 14, the player 18 can practice skateboarding while listening to music through the headphones 16.

  In the above embodiment, a series of movements from the first turn to the right and the right turn to the left is checked, but the first turn to the left, the left turn and then the right turn. You may make it check.

  In the above embodiment, the time from turning right or left to turning left or right is limited. However, a series of movements of turning left or right after turning right or left. It is possible to limit the time for performing the movement once, or limit the time for performing this series of movements a predetermined number of times.

  In the above embodiment, the time limit is provided only for the slalom, but the time limit may be provided only for the switch, or the time limit may be provided for both the slalom and the switch.

  The headphones 16 may be connected to the PDA 14 wirelessly instead of wired. Further, speakers may be attached to the left and right sides of the skateboard 12 instead of the headphones 16.

  Moreover, in the said embodiment, although the evaluation sound is output as a success sound, you may make it output a success sound separately from an evaluation sound. For example, a success sound may be output when all of the slalom and the switch are successful.
