Definitions

  • the present invention relates to an electronic competition system and method for playing an electronic competition among a plurality of competitors, and more particularly, to an electronic competition system and method for playing a shooting competition in which a plurality of competitors compete in score which is calculated according to a strike point of each light bullet discharged to a target through manipulations on a light-beam gun, in place of a real bullet firing competition which uses real bullets.
  • the light-beam gun when the light-beam gun is connected to a computer through an electric wire, the electric wire can subtly affect the senses of competitors, which are well-sharpened, to damage the mental tranquil and concentration. Therefore, there is a need for eliminating the connection of the light-beam gun with the computer through the electric wire.
  • the light-beam gun is also required to provide a competition level of accuracy for detecting a strike point of laser light emitted therefrom in an optical system, and is also required to ensure the safety because the laser light is emitted therefrom.
  • the light-beam gun is further required to improve the exactitude and speed of competition score counting processing on top of the foregoing requirements fully satisfied.
  • FIG. 1 is a diagram illustrating an exemplary configuration of a conventional electronic competition system which uses a laser gun which emits laser light for shooting.
  • the prior art example comprises laser gun 115 which is operated by a competitor for discharging an light bullet 162 implemented by laser light; strike point detector 116 which has a target board 117 removably mounted thereon, which receives light bullet 162 discharged from laser gun 115 , for detecting a strike point of light bullet 162 on target board 117 ; competitor PC 114 installed near a shooting seat for displaying a resulting strike detected by strike point detector 116 ; and a switching unit 101 for connecting strike point detector 116 with competitor PC 114 .
  • Switching unit 101 comprises a switching hub for LAN 141 of 10BASE-T.
  • FIG. 2 is a diagram for describing how a competition is played in the electronic competition system illustrated in FIG. 1.
  • a plurality of strike point detectors 116 shown in FIG. 1 are disposed in correspondence to a plurality of shooting boxes, each of which is defined by two partition boards 142 . While FIG. 2 shows five sets of shooting boxes and strike point detectors 116 by way of example, the number of the sets is not limited.
  • One shooting box and one strike point detector 116 are in one-to-one correspondence with respect to position as well as competition, so that in principle, light-beam guns will never discharged from a single shooting box to a plurality of strike point detectors 116 .
  • square or circular target board 117 is mounted on the front face of each strike point detector 116 .
  • a common plane 151 is formed by the front faces of respective target boards 117 , while each shooting box is formed with common permissible shooting plane 152 .
  • Common plane 151 and common permissible shooting plane 152 are in parallel with each other, and are both vertical planes.
  • the distance between common plane 151 and common permissible shooting plane 152 is shown to be 10 m or 25 m, by way of example, based on a particular play item.
  • the shooting box has a lateral width on common permissible shooting plane 152 set at 1 m when one gun is corresponded to one target, but is variably defined when one gun is corresponded to n targets.
  • the lateral width of the strike point detector 116 is shown to be 30 cm, by way of example, and two adjacent strike point detectors 116 has a center-to-center distance illustratively set at 1 m.
  • a light source for use in generating light bullet 162 discharged from laser gun 115 is, for example, a semiconductor laser oscillation device.
  • strike point detector 116 transmits a conical beam 161 , generated by an infrared LED, toward the shooting box, so that the competitor is not allowed to discharge light bullet 162 unless conical beam 161 transmitted from strike point detector 116 is not received by laser gun 115 , i.e., unless laser gun 115 is not oriented to target board 117 within the shooting box, thereby ensuring the safety of the competition.
  • target board 117 is involved in generating a signal which constitutes a sufficient condition for permitting the competitor to discharge light bullet 162 from laser gun 115 , the competition is not driven by the gun but by the target, thereby resulting in an impartial competition system in which the will of the competition host (judge) is respected.
  • each conical beam 161 emitted from strike point detector 116 only reaches the opposing shooting box and does not reach two shooting boxes in principle. Further, in this system, since laser gun 115 need not transmit information to the outside except for light bullet 162 , laser gun 115 need not be connected to competitor PC 114 through a wire.
  • Light bullet 162 discharged from the muzzle of laser gun 115 travels straight in a direction in which laser gun 115 is oriented, as is the case with a real bullet discharged from a real bullet gun.
  • Light bullet 162 discharged from the muzzle of laser gun 115 has a signal uniquely corresponding to laser gun 115 .
  • Light bullet 162 has high parallel convergence and therefore strikes on target board 117 in the shape of light spot.
  • strike point detector 116 As light bullet 162 discharged from laser gun 115 strikes on target board 117 mounted on strike point detector 116 , the strike point is detected by strike point detector 116 which transmits information on the detected strike point to competitor PC 114 through switching unit 101 .
  • strike point detector 116 has an adjustment function for increasing an electric, mechanical and optical accuracy of an optical device for detecting the position, the strike point of the laser light can be detected at a competition level of accuracy.
  • Competitor PC 114 calculates a score for shooting based on the strike point information transmitted from strike point detector 116 , and displays the calculated score. Since competitor PC 114 has previously registered with information which can identify a competitor such as a registration number of the competitor, as well as information such as the number of times the competitor has so far shot laser gun 115 , competitor PC 114 displays, simultaneously or with a delay, the registration number of the competitor, a bullet number, a score associated with the bullet number, a total score, a strike point of light bullet 162 on target board 117 .
  • a plurality of light bullets 162 are discharged from laser gun 115 in response to a single triggering operation.
  • scores of respective light bullets 162 can be averaged, but also a score can be found for each light bullet 162 .
  • Such a score counting method can give a score difference based on subtle vibrations of a hand after the trigger is pulled, evaluate characteristics such as swinging of the body of the competitor, and accordingly provide a new competition implementation which has not been so far available in a single real bullet shooting competition.
  • Light bullet 162 also includes a strike point detection signal for use in detecting a strike point, and an light bullet distinguishing signal for distinguishing this light bullet from others.
  • the strike point detection signal is transmitted to target board 117 even when the competitor is not triggering laser gun 115 , thereby permitting strike point detector 116 to detect the strike point. In this way, strike points of a plurality of light bullets 162 from single laser gun 115 can be traced as a continuous dot train.
  • a competitor In real bullet shooting, a competitor first confirms the feeing of the gun before starting a competition, and during the competition, shoots laser gun 115 on a trial basis not intended for getting a score before serious shooting intended for getting a score.
  • the electronic competition system also provides a serious shooting mode and a trial shooting mode for operation modes.
  • the competitor first confirms the feeling of laser gun 115 which is not conditioned to discharge light bullet 162 in a preparatory period before the start of a competition, switches the operation mode to the trial shooting mode after the competition is started for trial shooting not intended for a score, and again switches the operation mode to the serious shooting mode after completion of trial shooting for serious shooting intended for a score.
  • the electronic competition system available in recent years is safer than the real bullet shooting and has a high applicability in regard to the manner in which competitions are performed.
  • the electronic competition system as described above, it is anticipated that the population of competitors will take wing in the future as a general competition from the advantages mentioned above. It is also anticipated that the competition will be expanded to such an extent that competition meetings will take place on a national scale or on a global scale in the future.
  • the electronic competition system as described above is required to communicate the progress and result of a competition to competitors who participate in the competition, and spectators who watch the competition in a readily understandable way and in a variety of representations.
