<Embodiment>
<Structure>
FIG. 1 is an external view showing the appearance of the fencing mask 100. FIG. 2 is a diagram showing how the fencing mask 100 is attached to the fencing mask 100. Further, FIG. 3 is a pseudo cross-sectional view when viewed from the side surface with the Fencer wearing the mask 100. FIG. 4 is a view of the inside of the mask 100 as viewed from the back surface. In the present embodiment, the mask 100 for fencing will be described with a focus on a configuration different from the conventional one.

As shown in FIG. 1, the fencing mask 100 includes a face guard 101 that protects the front side and a head guard 102 that protects the crown side of the fencer.

As shown in FIGS. 3 and 4, the inside of the face guard 101 is provided with light emitting portions 10a and 10b. The light emitting units 10a and 10b are realized by, for example, LEDs, but are not limited thereto. The light emitting direction of the light emitting portions 10a and 10b faces the internal direction of the mask 100, that is, the fencer who is the wearer who wears the mask 100.

Further, as shown in FIGS. 3 and 4, the inside of the face guard 101 is provided with a power supply unit 20 for causing the light emitting units 10a and 10b to emit light. The power supply unit 20 is realized by, for example, a lithium ion battery, but is not limited thereto.

As shown in FIG. 4, a shock absorbing material is provided inside the mask 100. The shock absorbing material may be realized by, for example, cotton or sponge, but is not limited thereto. As shown in FIG. 3, a shock absorbing material is interposed between the face guard 101 and the fencer, and a gap exists between the shock absorbing material 30 and the face guard 101. The light emitting units 10a and 10b and the power supply unit 20 are provided on the mask 100 so as to exist in this gap. Therefore, although the light emitting units 10a and 10b illuminate the inside of the mask 100, the eyes of the fencer are not directly irradiated with the light, so that the fencer is not dazzled even if the light emitting units 10a and 10b emit light. Then, by irradiating the face of the fencer inside with the light emitting portions 10a and 10b, the face of the fencer can be made to stand out as shown in FIG. 2, and the face of the fencer can be confirmed from the outside.

FIG. 5 is a block diagram showing a configuration example of the mask 100 for fencing. As shown in FIG. 5, it includes a light emitting unit 10a and 10b, a power supply unit 20, a communication unit 11, a detection unit 12, a storage unit 13, a setting unit 14, and a control unit 15. As shown in FIG. 5, each part of the mask 100 is communicably connected to each other. This communication shall be wired or wireless.

The light emitting units 10a and 10b are LEDs that emit light according to instructions from the control unit 15. The emission color by the light emitting units 10a and 10b may be fixed or may be determined by the control unit 15.

The power supply unit 20 is a power source that provides power for driving each unit of the mask 100. The power supply unit 20 may be a rechargeable secondary battery or a commercially available primary battery.

The communication unit 11 is a communication interface having a function of executing communication with an external device. The communication unit 11 receives, for example, the sensing data detected by the sensors provided in each unit of the fencing wear and transmits the sensing data to the control unit 15. Here, the sensor may be a contact sensor, a pressure-sensitive sensor, or another sensor that can determine whether or not the opponent's sword has touched the fencer. The contact sensor is a sensor that outputs a signal indicating that there is contact when something comes into contact with the detection surface at the arranged position. When a contact sensor is used, identification information unique to each contact sensor is given, and information on each contact sensor and its placement position (torso, upper right arm, upper left arm, right thigh, etc.) is stored. By setting it, it is possible to detect which part of the contact was made. In the case of a contact sensor, since it only knows whether there was contact, it is not possible to know whether the contact was due to the sword, so it is separately determined whether the sword touched or a part of the opponent's body touched. There is a need to. The pressure-sensitive sensor is a sensor that detects the place where pressure is applied and the strength of pressure in the detection surface when pressure is applied to the detection surface, and outputs the information. In the case of a pressure-sensitive sensor, depending on whether the pressure is detected by a point, a line, or a surface, sword piercing, sword slashing, and contact with an opponent are detected, respectively. It can be detected separately, and the contacted part can be specified by the position information of the part where the pressure is detected.

The detection unit 12 is a sensor provided on the mask 100, and detects the contact of the opponent's foil (sword) and transmits it to the control unit 15. A contact sensor or a pressure-sensitive sensor can be used as the detection unit 12, but the detection unit 12 is not limited thereto. The detection unit 12 may be provided in various places of the mask 100 and the fencing wear, and each sensor provided in each place is assigned a unique ID.

The storage unit 13 is a storage medium having a function of storing various data and programs for driving the mask 100. The storage unit 13 stores the setting information 600 and the emission color information 610. Details of the setting information 600 and the emission color information 610 will be described later. Further, the storage unit 13 may hold information on which part of the body of the fencer the sensor corresponds to, and the ID assigned to each sensor is associated with each part. It may be the information given.

The setting unit 14 sets the competition event performed by the fencer wearing the mask 100. In the case of fencing, there are foil, épée, and saber events, each with different effective aspects. The effective surface is the part of the human body where the attack is judged to be effective. In the case of foil, the effective surface is "chest, abdomen, back", in the case of Epe, the effective surface is "whole body", and in the case of saber, the effective surface is "slightly above the waist to the entire upper body". Therefore, since the place where the attack is effective differs depending on the sport, the setting unit 14 may accept the input of the setting via the communication unit 11, or the mask 100 may be provided with a DIP switch or the like. You may accept the input of the setting. The setting unit 14 transmits the information of the set competition event to the control unit 15.

The control unit 15 is a processor that controls each unit of the mask 100 according to a program stored in the storage unit 13. The control unit 15 causes the light emitting units 10a and 10b to emit light based on the sensing data transmitted from the communication unit 11 or the detection unit 12. At this time, the control unit 15 may change the emission color depending on whether or not the attack from the opponent received by the fencer is effective, and the location where the attack is received.

The above is an example of the functional configuration of the mask 100.

<Data>
FIG. 6A is a data conceptual diagram showing a configuration example of the setting information 600. The setting information 600 is information indicating a place where the attack is effective for each sport, and is information that can identify a detection unit (sensor) provided at the place where the attack is effective.

As shown in FIG. 6A, the setting information 600 is information in which the competition item 601, the effective surface 602, and the corresponding sensor ID 603 are associated with each other.

The competition item 601 is information that can identify the competition item, and here, the name of the competition item is shown. If the competition item 601 can uniquely identify the competition item, the identification information (ID) assigned to the competition item may be used instead of the competition item.

The effective surface 602 is information indicating the surface on which the attack is effective in the corresponding sport 601. The effective surface is defined as a rule of the competition.

The corresponding sensor ID 603 is identification information of a sensor that can uniquely identify the detection unit 12 (sensor) arranged on the fencing wear or the mask 100 on the corresponding effective surface 602.

In the example shown in FIG. 6A, for example, when the sport is "foil", the effective surface is "chest, abdomen, back", and the sensor provided corresponding to the effective surface is "foil". It can be understood that "S0012, S0013, ...". The above is the description of the setting information 600.

FIG. 6B is a data conceptual diagram showing a configuration example of the emission color information 610. As shown in FIG. 6B, the emission color information 610 is information that defines the emission color that causes the light emitting units 10a and 10b to emit light according to the state of the fencer in the game.

As shown in FIG. 6B, the emission color information 610 is information in which the state 611 and the emission color 612 are associated with each other.

The state 611 is information indicating the state of the fencer, and is information indicating whether or not the attack has been made, and if the attack has been made, whether or not the attack is effective. In FIG. 6 (b), the “normal time” when not under attack, the “effective time” when the attack is effective after being attacked, and the case where the attack is not effective after being attacked. 3 examples of "when not valid" are shown.

The emission color 612 is information that defines the emission color that causes the light emitting units 10a and 10b to emit light in the state indicated by the corresponding state 611. The emission color setting may be arbitrary.

In the example shown in FIG. 6B, for example, when an attack is received and the attack is effective, the light emitting units 10a and 10b are made to emit light in pink. The above is the description of the emission color information.

<Operation>
FIG. 7 is a flowchart showing an operation example of the mask 100 for fencing. The flowchart shown in FIG. 7 shows the control contents by the control unit 15.

The setting unit 14 of the mask 100 accepts the setting of the competition item from the fencer (step S701). The setting unit 14 transmits the received setting contents to the control unit 15.

The control unit 15 causes the light emitting units 10a and 10b to emit light in a specified color (step S702). As an example, as normally shown in the emission color information 610, the emission is made in white.

The control unit 15 determines whether the sensing data has been received from the detection unit 12, that is, whether the detection unit 12 has detected the contact (step S703). The sensing data includes a sensor ID. If the sensing data is not received from the detection unit 12 (NO in step S703), the process proceeds to step S707.

When the sensing data is received from the detection unit 12 (YES in step S703), it is specified which part of the fencer was attacked based on the sensor ID included in the sensing data (step S704).

Then, based on the specified part (sensor ID) and the set competition item, the setting information 600 is referred to to specify whether or not the attack is effective. Then, depending on whether or not the attack is effective, the emission color is specified with reference to the emission color information 610 (step S705).

Then, the control unit 15 causes the light emitting units 10a and 10b to emit light with the specified emission color (step S706).

If the power of the mask 100 is turned off (YES in step S707), the process is terminated, and if it is not turned off (NO in step S707), the process returns to the process of step S701. The above is a description of the operation of the mask 100.

<Summary>
As described above, the mask 100 includes a light emitting unit that emits light toward the inside thereof. Therefore, when the mask 100 is worn by the fencer, the light emitting unit also illuminates the face of the fencer. As a result, it is difficult to see the face of the fencer inside the mask 100 from the outside when nothing is done, but the light emitting portions 10a and 10b emit light to brighten the inside of the mask 100. , Fencer's face can be visually recognized as if it emerges on the face guard 101. In addition, by changing the emission color of the light emitting part, it is possible to confirm at a glance whether or not the attack received by the fencer in the competition is effective.

<Supplement>
Needless to say, the apparatus according to the above embodiment is not limited to the above embodiment, and may be realized by other methods. Hereinafter, various modification examples will be described.

(1) In the above embodiment, the communication unit 11, the detection unit 12, the storage unit 13, and the control unit 15 are not indispensable configurations, and the fencing mask 100 simply illuminates the face of the fencer with light emitting units 10a and 10b. It may be configured to include only the power supply unit 20 and the power supply unit 20.

(2) In the above embodiment, an example of changing the emission color emitted by the light emitting units 10a and 10b depending on the attack and whether or not the attack is effective is shown, but the trigger for changing the emission color is It is not limited to this.

For example, in order to clarify which part was attacked, the emission color may be changed for each part. Alternatively, while Foil and Epe are effective only for piercing, in the case of Sabure, piercing and slashing are also effective, so the emission color may be changed according to the type of attack. ..

Further, when a pressure sensor or the like is used as the detection unit 12, the effectiveness of the attack may be determined according to the strength of the pressure. For example, if the pressure detected by the pressure sensor is equal to or higher than a predetermined threshold value, the attack may be enabled, and if it is less than the threshold value, it may be determined to be invalid, and the emission color may be changed.

(3) In the above embodiment, an example in which two light emitting units, that is, a light emitting unit 10a and 10b, is provided as the light emitting unit is shown, but the number of light emitting units is not limited to two. It may be one, or three or more may be provided. Further, at that time, if the light emitting portion can be configured to illuminate the inside of the mask 100 so that the face of the fencer emerges on the face guard 101 and does not directly irradiate the eyes of the fencer, the position shown in FIG. 1 or the like. It may be arranged in a part other than the above. As an example, the light emitting portion may be provided on the side surface of the mask 100 at a position corresponding to the position of the cheek of the fencer.

(4) In the above embodiment, the mask 100 changes the emission color depending on whether or not the fencer wearing the mask 100 has been attacked by an opponent and whether or not the attack is effective. However, the trigger for changing the emission color is not limited to the presence or absence of an attack. The mask 100 may change the emission color depending on the position of the fencer, for example.

FIG. 8A is a schematic diagram showing an overview of a fencing match. As shown in FIG. 8A, fencing is a competition in which fencers compete against each other on a fixie 800. The pist 800 is an area having a width of 1.5 m to 2 m and a length of 14 m, and a battle is performed in this area. The width of the fix 800 varies depending on the content of the competition. The central portion of the pist 800 shown in FIG. 8A is defined as a center line, and a position 7 m to the left and right of the drawing from the center line is defined as a rear limit line or a rear boundary line. If the fencer crosses this rear boundary with both feet, points will be added to the opponent. That is, in the example of FIG. 8A, if the player on the right side crosses the rear boundary line on the right side of the drawing with both feet, the player on the left side will be scored, and conversely, the player on the left side will be scored. If both feet cross the rear boundary on the left side of the drawing, a dot will be placed on the player on the right side.

Therefore, the mask 100 may be configured to change the emission color of the light emitting units 10a and 10b so that the position of the fencer can be known depending on the distance to the rear boundary line. That is, the mask 100 may be configured so that the emission color changes as the fencer approaches the rear boundary line.

As an example for realizing this configuration, transmitters 810 are provided at both ends of the pist 800 at positions that do not get in the way even if the fencer retracts and emit a predetermined radio wave behind each rear boundary line. .. The transmitter 810 is a communication device that transmits a predetermined radio wave at a predetermined cycle (for example, every 0.1 seconds). The radio wave includes an identification number unique to each transmitter 810 for identifying the transmitter 810. Then, the communication unit 11 of the mask 100 receives the radio wave from the transmitter 810.

Further, the storage unit 13 of the mask 100 may store the emission color information 820 as shown in FIG. 8B. The emission color information 820 shown in FIG. 8B is information in which the emission color that causes the light emitting units 10a and 10b to emit light corresponding to the radio wave intensity and the specified radio wave intensity are associated with each other. In the example of FIG. 8B, when the radio wave intensity is weak, the emission color becomes white when the distance from the transmitter 810 is long. Further, the fact that the radio wave strength is strong means that the distance from the transmitter 810 is short, it means that the rear boundary line is close, and the emission color is orange because there is a possibility of a goal for the fencer. Here, the radio field strength is expressed as strong, medium, and weak, but this does not have to be in these three stages, and may be in two stages of strength and weakness, and the strength of the radio wave strength. It may emit light with a corresponding gradation. Further, although the radio wave intensity is expressed as strong, medium and weak here, this may be expressed by a threshold value or a range of the decibel value.

FIG. 9 is a flowchart showing an operation example of the process of changing the emission color according to the position of the fencer by the mask 100. As shown in FIG. 9, the communication unit 11 of the mask 100 receives the radio wave transmitted from the transmitter 810 (step S901). When the received radio wave is a radio wave from a predetermined transmitter 810 (transmitter 810 arranged behind the fencer), the communication unit 11 measures the reception strength thereof (step S902). The reception intensity may be measured by using the prior art. The communication unit 11 transmits the measured radio field strength to the control unit 15.

The control unit 15 identifies the strength, medium and weakness of the radio wave intensity from the transmitted radio wave intensity, and specifies the emission color using the emission color information 820 (step S903). Then, the control unit 15 causes the light emitting units 10a and 10b to emit light in the specified emission color (step S904). If the power of the mask 100 is turned off (YES in step S905), the process is terminated, and if it is not turned off (NO in step S905), the process returns to the process of step S901. The above is a description of the operation of the mask 100.

The processes shown in FIGS. 7 and 9 may be executed in parallel, or only one of them may be executed. The process shown in FIG. 9 may be a process for determining the emission color that constantly illuminates the inside of the mask 100, and when the processes shown in FIGS. 7 and 9 are executed in parallel, the emission color may be changed at the same time. If it occurs, the process of FIG. 7 is prioritized, the emission color determined in FIG. 7 is emitted for a predetermined time (for example, 2 seconds), and then the emission color is switched to the emission color determined in the process of FIG. It may be configured in.

Further, the method of specifying the position of the fencer is not limited to the example described with reference to FIGS. 8 and 9. If the position of the fencer can be specified, another method may be used. For example, a distance sensor is installed instead of the transmitter 810, and the distance sensor calculates the distance to the fencer. As the distance sensor, an ultrasonic sensor or a radar sensor can be used. An ultrasonic sensor calculates a distance based on the time required to emit a sound wave and receive the reflected wave. Further, the radar sensor calculates the distance based on the time required for emitting a light wave and receiving the reflection thereof. Then, the distance sensor transmits the calculated distance to the mask 100. The mask 100 may calculate the distance detected by the distance sensor and the distance from the position where the distance sensor is arranged to the rear boundary line, and switch the emission color according to the distance.

Alternatively, a pressure-sensitive sensor may be provided on the entire surface under the fixie 800, and the position of the fencer may be specified by the pressure position detected by the pressure-sensitive sensor.

In this way, various methods may be used to specify the distance from the fencer to the rear boundary line and switch the emission color. This allows the fencer to roughly know how far he is now to the rear border and can be the information he refers to when considering the match.

(5) Further, in the above embodiment, as a method of causing the light emitting unit in the mask for fencing to emit light, the processor (control unit) of the apparatus executes a program or the like to emit light. It may be realized by a logic circuit (hardware) or a dedicated circuit formed in an integrated circuit (IC (Integrated Circuit) chip, LSI (Large Scale Integration)) or the like in the apparatus. Further, these circuits may be realized by one or a plurality of integrated circuits, and the functions of the plurality of functional units shown in the above embodiment may be realized by one integrated circuit. LSI may be referred to as VLSI, super LSI, ultra LSI, or the like depending on the degree of integration.

Further, the above program may be recorded on a recording medium readable by the processor, and the recording medium may be a "non-temporary tangible medium" such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like. Can be used. Further, the program may be supplied to the processor via any transmission medium (communication network, broadcast wave, etc.) capable of transmitting the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the walking teaching program is embodied by electronic transmission.

The above program can be implemented using, for example, a script language such as C ++, ActionScript, JavaScript (registered trademark), an object-oriented programming language such as Objective-C, Java (registered trademark), and the like.

(6) The various examples shown in the above embodiments and supplements may be combined as appropriate.
