ＲＳ_Ｒ＝（ａ_Ｐ・ＲＳ_Ｐ＋ｂ_Ｐ−ｂ_Ｒ）／ａ_Ｒ …（５）
が得られる。
【００１７】
以下、上述の原理に基づく実施形態について説明する。
図１は上述の体感競技中継装置を実現するための一実施形態の全体の構成を示すブロック図である。
【００１８】
図１において、体感競技中継装置は、競技場１で競技者２が装着する情報取得装置３と中継装置４および家庭５に設置される再生装置６とから構成されている。情報取得装置３と中継装置４との間は近距離の無線通信を通じて行なわれ、中継装置４と再生装置６との間は通常のＴＶ放送によって実現される。
【００１９】
情報取得装置３は周囲の音を集音するマイクロホン３１と、周囲の景色を撮像するビデオカメラ３２と、温度や湿度や風向や風速などの気象情報を測定する気象センサ３３と、実際に体感競技で走行する前に脈拍を検出するための脈拍センサ３４と、これらによって取得された情報を送信するデータ送信機３５とによって構成される。マイクロホン３１とビデオカメラ３２と気象センサ３３は競技環境検出手段を構成し、データ送信機３５とともに競技者が被る帽子に装着することができる。脈拍センサ３４は競技者の耳や手首などに張り付けられ、体感競技前に脈拍や安静脈拍数を検出するが、脈拍数の検出は体感競技では行われない。データ送信機３５からの各種情報の送信は時分割方式など種々考えられる。このような情報取得装置３は視聴者が体感を希望する競技者全員が装着する。
【００２０】
情報取得装置３で取得された情報は競技場１に設置されている中継装置４に個別的に伝送される。中継装置４は受信装置４１、情報抽出装置４２、放送装置４３とから構成されている。受信装置４１は各情報取得装置３から送信されてきた各種情報を受信する。なお、図示しない競技者２の後方から中継車によって捉えられた追跡映像も中継装置４に送信されてきており、情報抽出装置４２は各競技者から送られる視野情報を抽出し、それらを放送装置４３によってＴＶ放送電波で送信可能なフォーマットに変換し、各家庭に放送される。なお、情報抽出装置４２は脈拍センサ３４で検出された脈拍に基づいて運動負荷を算出するとともに各競技者の運動能力係数なども競技に先立って算出する。
【００２１】
一方、家庭５の再生装置６には家庭内受信装置７が設けられている。家庭内受信装置７は放送受信装置７１と視野情報のデコード装置７２と体感提示装置駆動システム７３とユーザモニタ７４とを含む。放送受信装置７１は中継装置４からのＴＶ放送を受信し、視野情報がデコード装置７２に与えられる。視聴者はこのデコード装置７２により注目している競技者の視野情報を選択できる。駆動システム７３は選択された視野情報に基づいて疲労付与手段と競技体験手段を駆動する。
【００２２】
ここで、競技体験手段は視聴者８がその上に乗ってランニングするトレッドミル９と、画像情報に基づいて周囲の映像を表示するモニタディスプレイ１０と、周囲の音を再生するスピーカ１１と、向かい風を送る送風装置１２と、所定の気温および湿度を与える空調装置１３を含む。また、トレッドミル９の速度を速くしたり、送風装置１２による向かい風を強くしたり、空調装置１３による気温および湿度の上昇によって視聴者８に疲労を与えることができ、これらは疲労付与手段を構成している。
【００２３】
なお、視聴者８の後方に別の逆風装置を設置すれば視聴者８に追風を与えることができ、この場合は視聴者８の疲労を軽減できる。
【００２４】
さらに、マラソンに限ることなくトレッドミル９を傾斜させて、登山を想定する場合には、気圧や酸素濃度を変化させて、視聴者に疲労を与えることができる。
【００２５】
また、視聴者８は事前に、耳などに脈拍センサ１４を張り付けて走行を行なうが、競技体感中においては脈拍センサ１４は必要とされない。脈拍センサ１４からの情報は視聴者８が被る帽子に取付けられたデータ送信機１５を介してユーザモニタ７４に伝送される。また、視聴者８の走行状態や生理状態がモニタ用ビデオカメラ１６によって撮像され、ユーザモニタ７４に与えられる。
【００２６】
したがって、この実施形態によれば、モニタディスプレイ１０には競技者２が走行している周囲に見える視野の映像が表示され、モニタスピーカ１１からは競技者２の周囲で聞こえる音などがステレオ音として再生され、送風装置１２からは競技者２の走行速度と競技場の風の状態から推定された風向きと風力の風が送られる。さらに、空調装置１３からは競技場１と同じ温度と湿度の気象条件が与えられる。
【００２７】
その結果、視聴者８は競技場１で走行している競技者２固有の感動や興奮を家庭で体験できる。
【００２８】
なお、図１に示した実施形態では、音はマイクロホン３１で検出し、視野の映像はビデオカメラ３２で撮像し、気象情報は気象センサ３３で検出し、生理情報は脈拍センサ３４で検出するようにしたが、これらは従来から広く知られているものを用いることができる。しかし、競技者２の走行速度については既存の方法では困難である。
【００２９】
そこで、この発明の実施形態では、走行時の走行速度がピッチに反比例する現象に着目し、このピッチ情報から走行速度を推定する。ここでのピッチとは、走行において足が地面に交互に接地する周期である。特に、この実施形態では、ピッチを直接計測するためのセンサを別に用いることなく、競技者２の視野情報の１つである画像情報からピッチを計測する。これにより、競技者２に装着するセンサが減ることで競技者の機器装着感が改善され、また送信情報の量も低減できる。
【００３０】
図２はこの発明の一実施形態における走行速度計測アルゴリズムを示すフローチャートであり、図３は走行速度を計測する上での画像フレームを示す図である。
【００３１】
競技者２に装着したビデオカメラ３２から得られる画像（図２（ａ））は走行動作に伴って上下に振動している。まず、画像処理によってこのビデオ信号を構成する各フレーム間でその振動の状態が得られる。図３（ａ）に示すようにここでは対象フレームの１フレーム前（ｎ−１）の画像の中央部のイメージが対象フレーム（ｎ）のどの部分に移動したかが調べられる。その結果、図３（ｂ）に示すように、水平移動成分ｄｘと垂直移動成分ｄｙが得られるが、このうちの垂直移動成分ｄｘのみをこのフレームでの振動情報として使用される。これにより、競技者２が走行中に任意の方向を見たとしても、走行に伴う上下の移動情報には影響を及ぼさないために、安定した振動情報の検索ができる。
【００３２】
上述のごとくして得られた時系列振動情報（図２（ｂ））に対してＦＦＴフィルタを作用させると、そのスペクトル（図２（ｃ））から人間の走行ピッチの範囲内でのスペクトルの最大成分がピッチとして取得される。なお、この手順で定まるピッチは離散値であり、離散値のピッチから競技者２の走行特性により求まる推定走行速度もまた離散値となる。この離散値のピッチによって得られた速度をそのままトレッドミル９上で再生してしまうと、僅かなピッチの変化でも急な速度変化が生じてしまい危険となる。このため、ピッチを連続的に変化させる必要があるが、ここではその方法としてスプライン補完を用いて連続値（図２（ｄ））を得ている。
【００３３】
以上の手順により映像からの推定走行速度（図２（ｅ））は連続して得られるが、ＦＦＴのデータ取得のために速度算出処理が映像に対して数秒遅れてしまう。これは中継時に中継装置４内で映像を遅らせる処理によって解決することができる。
【００３４】
走行ピッチの計測例としては、通常の放送の中継映像から画像処理によって計測する方法が既に提案されているが、いずれも別に初期設定が必要であるとともに、時々刻々と変化する撮影条件が変化した場合には、初期設定を再度やり直すなどの手間を必要とするが、この実施形態ではこのような初期設定が不要となる。
【００３５】
次に、競技者と視聴者の疲労感を一致させる動作について説明する。
図４は競技者と視聴者の疲労感を一致させるための運動量の再生を調整する動作を示すブロック図であり、図５はフローチャートであり（ａ）は事前の計測動作を示し、（ｂ）は体感競技の動作を示す。
【００３６】
まず、体感競技を行う前に、図５（ａ）に示すようにステップ（図示ではＳと略称する）Ｓ１において、事前に脈拍センサ３４によって、競技者３と視聴者８の安静時の脈拍数ＰＲｒｅｓｔを計測し、（２２０−年齢）から最高脈拍数ＰＲｍａｘを算出する。そして、ステップＳ２で何通りかの速度Ｖｋ（ｋ＝１〜ｎ）で競技者３と視聴者８とを走らせ、そのときのそれぞれの脈拍ＰＲｋ（ｋ＝１〜ｎ）を計測する。ステップＳ３において、速度Ｖｋ（Ｖｋ＝１〜ｎ）で走ったときの競技者と視聴者の運動負荷ＷＬｋ（ｋ＝１〜ｎ）を、それぞれの最高脈拍数ＰＲｍａとＰＲｋ（ｋ＝１〜ｎ）とから第（１）式により求める。ステップＳ４において速度Ｖｋと運動負荷ＷＬｋとの関係から一次回帰してそれぞれの回帰直線の運動能力係数ａ，ｂを求める。これらの運動能力係数ａ，ｂは、図１に示した体感提示装置駆動システム７３に予め登録される。
【００３７】
体感提示装置駆動システム７３は、状態比較機構７３１と走行速度のスケール変換機構７３２を有している。そして、体感競技において、図５（ｂ）に示すように、状態比較機構７３１には、前述のごとく登録された競技者３の運動能力係数ａ，ｂが与えられていて、状態比較機構７３１はこの登録されている情報を参照しながら、走行負荷のスケール変換機構７３２により、トレッドミル９によって提示する走行負荷のスケール変換を行なう。
【００３８】
すなわち、スケール変換機構７３２は、ステップＳ５で計測された競技者３の走行速度ＲＳ_Ｐから競技者３の感じている運動負荷ＷＬｐを推定し、ステップＳ６でその運動負荷に見合った視聴者の走行速度ＲＳｒを第（５）式から算出し、その実走行速度でトレッドミル９を駆動する。それによって、競技者３が感じる疲労感と視聴者８が感じる疲労度を一致させる走行速度でトレッドミル９を駆動できる。
【００３９】
なお、上述の実施形態では、競技者３がマラソンランナーであり、このマラソンランナーの走行速度を送信し、視聴者８がトレッドミル９の上でランニングする例について説明したが、これに限ることなく競技が自転車競技あるいはボート競技であれば、トレッドミル９に代えてローイングマシンやエルゴメータなどを用いれば、視聴者８が競技者３と同様の体感を得ることができる。この場合、送信する情報としては、走行速度に代えてオールを漕ぐ強度、ペダルを踏みこむ強度などのように物理的に計測可能な情報を用いればよい。
【００４０】
なお、今回開示された実施の形態は全ての点で例示であって、制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。
【００４１】
【発明の効果】
以上のように、この発明によれば、競技者の運動強度情報と予め測定された競技者の運動能力係数とに基づいて運動負荷を推定し、競技者の運動強度から同じ運動負荷を与える視聴者の実運動強度を演算し、その実運動強度で視聴者に疲労を与えるように疲労度付与手段を制御するようにしたので、競技者の競技中における疲労感や苦しさ，辛さなどを一致させて視聴者自身の動きとして体験できる。

BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a bodily sensation relay device, and for example, a player who is actually competing, such as a marathon, a boat race, or a bicycle race, views the tired feeling, the pain, the pain, that is, the feeling of fatigue in a match. It is related with a bodily sensation competition relay device that can be experienced as a person's own exercise.
[0002]
[Prior art]
Currently, there are two ways to enjoy sports: “competition using one's own body” and “watch competitions performed by others”. The former “competition with your own body” is a way to experience the fun of sports directly by actually playing the sport.
[0003]
On the other hand, the latter “watching a competition performed by another person” is a method of indirectly enjoying a sport through watching the competition. The latter can be further classified into two types: watching at a venue where the competition is held, and watching at a remote location such as sports broadcasting such as TV broadcasting. It is the most attractive to experience the atmosphere of the venue by going to the venue directly at the venue, and it is attractive to be able to watch sports broadcasts performed in conventional broadcasting while staying in a remote place . In recent broadcasting, various additional information is added to video and the actual situation, and more detailed relaying is performed.
[0004]
[Problems to be solved by the invention]
However, since each method is a watching from an objective point of view of a third party, even though the excitement and state of the venue can be transmitted, it is difficult to convey the feeling of the competitors and the enjoyment of sports.
[0005]
Accordingly, the inventors of the present application have proposed a “physical competition relay device” in Japanese Patent Application No. 11-155534. In this bodily sensation competition relay device, when a marathon relay is taken as a specific example, a camera that shoots a video viewed from the player's viewpoint is attached to the player's head, and the video and information such as the player's running position and speed are displayed. In addition, it is relayed to the home, and a movement sensation generating device and a large screen are arranged on the home side, so that the impression that the subject has experienced the race more actively than the conventional relay can be obtained. In this device, the belt is moved in synchronization with the running speed of the player as a movement sensation generating device, and the viewer simply runs passively on the belt. However, if the athletes and viewers have different athletic abilities, the pain and pain that they feel should be different.
[0006]
Therefore, the main purpose of the present invention is not that the viewer exercises in accordance with the athlete's exercise intensity, but the player's feeling of fatigue, pain, and pain during competition, that is, fatigue and viewer's fatigue. It is an object of the present invention to provide a sensory competition relay device that can match the above.
[0007]
[Means for Solving the Problems]

It is characterized by comprising control means for calculating the actual running speed of the viewer for giving the corresponding exercise load and controlling the exercise load applying means so as to give the viewer the exercise load corresponding to the actual running speed. To do.
[0008]
Preferably, the first athletic ability coefficient is a coefficient for associating the athlete's running speed with the athlete's exercise load by linear regression, and the second athletic ability coefficient is the viewer's actual running speed. Is a coefficient for associating the viewer's exercise load with linear regression.
According to another aspect of the present invention, there is provided a sensible competition relay device that allows the viewer to experience an exercise that matches the exercise load of the running athlete and the exercise load of the viewer, and the exercise load is predetermined. Defined by the ratio of the difference between the pulse rate during exercise and the pulse rate at rest relative to the difference between the predicted maximum pulse rate derived from age and the pulse rate at rest derived from the given relational expression. Exercise intensity detection means for detecting speed, audiovisual information about the scenery and sound surrounding the athlete, and competition environment detection means for obtaining weather information about temperature, humidity, wind direction and wind speed around the athlete And transmitting the exercise intensity information corresponding to the running speed detected by the exercise intensity detection means and the audio-visual information detected by the competition environment detection means and the information of the competition environment corresponding to the weather information An image corresponding to the audiovisual information and allowing the viewer to perform an exercise having an exercise load based on the exercise intensity information, and receiving means for receiving the exercise intensity information and the competition environment information transmitted by the transmission means And a competition experience means for reproducing the sound and reproducing the temperature, humidity, wind direction and wind speed corresponding to the weather information for the viewer to experience, the competition experience means provides the viewer with the instructed exercise load.

[0009]
DETAILED DESCRIPTION OF THE INVENTION
First, the principle of the present invention will be described before describing the sensation game relay apparatus according to an embodiment of the present invention. The present invention is to allow the viewers to compete in the player's standpoint so that the actual competition can be experienced up close, and at the same time, the fatigue of the players and viewers can be matched. Here, even if it is said to be fatigue, physiological and mental definitions are multiple, and it is generally difficult to directly measure and control the fatigue itself.
[0010]
Therefore, the present invention is characterized in that the control is performed via an exercise load that is a factor of fatigue. The exercise load is an index indicating how much work the person is performing with respect to the maximum work ability of the exercise of the person. And it is thought that fatigue is accumulated and strengthened by continuing exercise with a certain exercise load. In other words, if the exercise load of the competitor and the viewer is measured and the amount of exercise is controlled so that the two match, the result is thought to result in a sense of fatigue.
[0011]
In the present invention, an exercise load measuring means using a pulse is used for the convenience of measurement. The exercise load (WL: Work Load) is an index indicating the current exercise load with respect to the maximum exercise load of the individual. Here, the exercise load WL is obtained by the following equation from the pulse rate PR (Pulse Rate) during exercise, the pulse rate PRrest at the time of stability, and the maximum pulse rate PRmax.
[0012]
WL = (PR−PRrest) / (PRmax−PR rest ) × 100 (1)
For the highest pulse, for example, the predicted highest pulse rate of (220-age) is used.
[0013]
In the following description, the marathon relay is targeted as an athletic competition, and the description will be applied to an athlete running at a certain speed. The running speed is applied as the exercise intensity in running. The traveling speed RS and the pulse rate PR have a relationship in which the traveling speed and the pulse rate increase approximately proportionally from a moderate load such as light running to a heavy load that runs violently. For this reason, a linear section as shown in FIG. 6 is also present in the relational expression between the exercise load WL and the running speed RS in the first equation (1) obtained from the pulse during exercise and constants (maximum pulse rate, safe vein rate). appear. Therefore, as shown in the formula (2), a characteristic straight line that associates the traveling speed RS and the exercise load WL by linear regression can be defined.
[0014]
WL = a · RS + b (2)
Here, a and b can be regarded as definitions representing individual characteristics by coefficients for obtaining the exercise load WL from the running speed RS. If these can be measured in advance, any exercise load can be calculated using the expression (2). Can be calculated. This straight line is defined as a characteristic line of athletic ability, and the coefficients a and b are referred to as athletic ability coefficients.
[0015]
In the following description, the speed of the athlete is referred to as “virtual speed”, and the converted speed at which the viewer actually travels is referred to as “real speed”. Now, the relationship between the running speed and the exercise load of the competitors and viewers is shown in Equation (3). Note that the subscripts P and R indicate the variables of the competitor and the viewer.
[0016]

Here, it is a condition that the exercise load matches, so
WL _P = WL _R (4)
It becomes. Therefore, substituting the expression (3) into the expression (4) and transforming it,
RS _R = (a _P · RS _P + b _P −b _R ) / a _R (5)
Is obtained.
[0017]
Hereinafter, an embodiment based on the above-described principle will be described.
FIG. 1 is a block diagram showing the overall configuration of an embodiment for realizing the above-described sensation game relay device.
[0018]
In FIG. 1, the bodily sensation competition relay device includes an information acquisition device 3 worn by a player 2 in a stadium 1, a relay device 4, and a playback device 6 installed in a home 5. The information acquisition device 3 and the relay device 4 are performed through short-range wireless communication, and the relay device 4 and the playback device 6 are realized by normal TV broadcasting.
[0019]
The information acquisition device 3 includes a microphone 31 that collects ambient sounds, a video camera 32 that captures the surrounding scenery, a weather sensor 33 that measures weather information such as temperature, humidity, wind direction, and wind speed, and a physical experience competition. It is comprised by the pulse sensor 34 for detecting a pulse before driving | running | working, and the data transmitter 35 which transmits the information acquired by these. The microphone 31, the video camera 32, and the weather sensor 33 constitute a competition environment detection means, and can be mounted on the hat worn by the athlete along with the data transmitter 35. The pulse sensor 34 is attached to the athlete's ear, wrist, etc., and detects the pulse and the vena cava rate before the bodily sensation competition, but the detection of the pulse rate is not performed in the bodily sensation competition. Various kinds of information transmission from the data transmitter 35 can be considered, such as a time division method. Such an information acquisition device 3 is worn by all the players who want the viewer to experience.
[0020]
Information acquired by the information acquisition device 3 is individually transmitted to the relay device 4 installed in the stadium 1. The relay device 4 includes a receiving device 41, an information extracting device 42, and a broadcasting device 43. The receiving device 41 receives various information transmitted from each information acquisition device 3. In addition, the tracking image captured by the relay vehicle from the rear of the player 2 (not shown) is also transmitted to the relay device 4, and the information extracting device 42 extracts the field-of-view information sent from each player and transmits them to the broadcasting device. 43 is converted into a format that can be transmitted by TV broadcast radio waves and broadcast to each home. The information extracting device 42 calculates the exercise load based on the pulse detected by the pulse sensor 34 and calculates the athletic performance coefficient of each athlete prior to the competition.
[0021]
On the other hand, the playback device 6 in the home 5 is provided with a home receiving device 7. The home receiving device 7 includes a broadcast receiving device 71, a visual field information decoding device 72, a sensation presentation device driving system 73, and a user monitor 74. The broadcast receiving device 71 receives a TV broadcast from the relay device 4, and visual field information is given to the decoding device 72. The viewer can select the visual field information of the player who is paying attention by using the decoding device 72. The drive system 73 drives the fatigue imparting means and the competition experience means based on the selected visual field information.
[0022]
Here, the competition experience means includes a treadmill 9 on which a viewer 8 rides and runs, a monitor display 10 that displays surrounding images based on image information, a speaker 11 that reproduces surrounding sounds, and a headwind And an air conditioner 13 that gives a predetermined temperature and humidity. Further, it is possible to increase the speed of the treadmill 9, to increase the head wind by the blower 12, and to give the viewer 8 fatigue by increasing the temperature and humidity by the air conditioner 13. doing.
[0023]
In addition, if another head wind device is installed behind the viewer 8, the viewer 8 can be given additional wind. In this case, the viewer 8 can be less fatigued.
[0024]
Further, when the treadmill 9 is inclined without being limited to the marathon and mountain climbing is assumed, the viewer can be fatigued by changing the atmospheric pressure or the oxygen concentration.
[0025]
In addition, the viewer 8 travels with the pulse sensor 14 attached to the ear or the like in advance, but the pulse sensor 14 is not required during a game experience. Information from the pulse sensor 14 is transmitted to the user monitor 74 via the data transmitter 15 attached to the hat worn by the viewer 8. Further, the running state and physiological state of the viewer 8 are captured by the monitor video camera 16 and given to the user monitor 74.
[0026]
Therefore, according to this embodiment, the monitor display 10 displays an image of a visual field that can be seen around the player 2 running, and the sound heard from the monitor speaker 11 around the player 2 is a stereo sound. The air blower 12 sends the wind direction and wind force estimated from the running speed of the competitor 2 and the wind condition of the stadium. Further, the air conditioner 13 gives the same weather conditions of temperature and humidity as the stadium 1.
[0027]
As a result, the viewer 8 can experience the excitement and excitement unique to the player 2 running in the stadium 1 at home.
[0028]
In the embodiment shown in FIG. 1, the sound is detected by the microphone 31, the visual field image is captured by the video camera 32, the weather information is detected by the weather sensor 33, and the physiological information is detected by the pulse sensor 34. However, those well known in the art can be used. However, it is difficult for the competitor 2 to travel with the existing method.
[0029]
Therefore, in the embodiment of the present invention, attention is paid to a phenomenon in which the traveling speed during traveling is inversely proportional to the pitch, and the traveling speed is estimated from this pitch information. Here, the pitch is a period in which the feet alternately touch the ground during running. In particular, in this embodiment, the pitch is measured from image information that is one of the visual field information of the player 2 without using a separate sensor for directly measuring the pitch. As a result, the number of sensors attached to the player 2 is reduced, so that the player's feeling of wearing the equipment is improved, and the amount of transmission information can be reduced.
[0030]
FIG. 2 is a flowchart showing a traveling speed measurement algorithm in one embodiment of the present invention, and FIG. 3 is a diagram showing an image frame for measuring the traveling speed.
[0031]
An image (FIG. 2A) obtained from the video camera 32 attached to the player 2 vibrates up and down with the running operation. First, the vibration state is obtained between each frame constituting the video signal by image processing. As shown in FIG. 3A, it is examined here to which part of the target frame (n) the image at the center of the image (n-1) one frame before the target frame has moved. As a result, as shown in FIG. 3B, a horizontal movement component dx and a vertical movement component dy are obtained, and only the vertical movement component dx is used as vibration information in this frame. As a result, even if the player 2 sees an arbitrary direction during running, the vertical movement information accompanying the running is not affected, so that stable vibration information can be searched.
[0032]
When the FFT filter is applied to the time-series vibration information obtained as described above (FIG. 2B), the spectrum within the range of the human running pitch is calculated from the spectrum (FIG. 2C). The maximum component is acquired as the pitch. Note that the pitch determined by this procedure is a discrete value, and the estimated traveling speed obtained from the running characteristics of the player 2 from the discrete pitch is also a discrete value. If the speed obtained by the discrete pitch is reproduced on the treadmill 9 as it is, a sudden speed change may occur even if the pitch is slightly changed. For this reason, it is necessary to continuously change the pitch, but here, a continuous value (FIG. 2D) is obtained using spline interpolation as the method.
[0033]
Although the estimated traveling speed (FIG. 2 (e)) from the video is continuously obtained by the above procedure, the speed calculation process is delayed for several seconds with respect to the video in order to acquire the FFT data. This can be solved by delaying the video in the relay device 4 at the time of relay.
[0034]
As examples of running pitch measurement, methods have been proposed to measure from broadcast images of normal broadcasts by image processing, but each requires initial settings, and the shooting conditions that change from moment to moment have changed. In this case, the initial setting is required again, but this initial setting is not necessary in this embodiment.
[0035]
Next, an operation for matching the feeling of fatigue of the athlete and the viewer will be described.
FIG. 4 is a block diagram showing an operation for adjusting the reproduction of the momentum for matching the feeling of fatigue between the player and the viewer, FIG. 5 is a flowchart, (a) shows a pre-measurement operation, and (b) Indicates the action of the sensation competition.
[0036]
First, before performing the bodily sensation competition, as shown in FIG. 5A, in step (abbreviated as S in the figure) S1, the pulse rate at the time when the athlete 3 and the viewer 8 are at rest by the pulse sensor 34 in advance. PRrest is measured, and the maximum pulse rate PRmax is calculated from (220-age). In step S2, the athlete 3 and the viewer 8 are run at several speeds Vk (k = 1 to n), and the respective pulses PRk (k = 1 to n) at that time are measured. In step S3, the athlete's and viewer's exercise load WLk (k = 1 to n) when running at the speed Vk (Vk = 1 to n) is set to the maximum pulse rate PRma and PRk (k = 1 to n). ) And the following equation (1). In step S4, linear regression is performed from the relationship between the velocity Vk and the exercise load WLk, and the exercise ability coefficients a and b of the regression lines are obtained. These athletic ability coefficients a and b are registered in advance in the sensation presentation device drive system 73 shown in FIG.
[0037]
The sensation presentation device drive system 73 includes a state comparison mechanism 731 and a travel speed scale conversion mechanism 732. In the bodily sensation competition, as shown in FIG. 5B, the state comparison mechanism 731 is provided with the athletic ability coefficients a and b of the player 3 registered as described above. With reference to the registered information, the travel load scale conversion mechanism 732 performs scale conversion of the travel load presented by the treadmill 9.
[0038]
That is, the scale conversion mechanism 732 estimates the exercise WLp feels athletes 3 from the traveling speed RS _P competitor 3 measured in step S5, the running of the viewer commensurate with the exercise in step S6 The speed RSr is calculated from the expression (5), and the treadmill 9 is driven at the actual traveling speed. Accordingly, the treadmill 9 can be driven at a running speed that matches the fatigue feeling felt by the player 3 and the fatigue feel felt by the viewer 8.
[0039]
In the above-described embodiment, an example has been described in which the athlete 3 is a marathon runner, the running speed of the marathon runner is transmitted, and the viewer 8 runs on the treadmill 9, but the present invention is not limited thereto. If the competition is a bicycle competition or a boat competition, the viewer 8 can obtain the same sensation as the athlete 3 by using a rowing machine or an ergometer instead of the treadmill 9. In this case, as information to be transmitted, information that can be physically measured may be used, such as strength for rowing instead of traveling speed, strength for stepping on a pedal, and the like.
[0040]
It should be understood that the embodiment disclosed this time is illustrative in all respects and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

【The invention's effect】
As described above, according to the present invention, an exercise load is estimated based on the athlete's exercise intensity information and the athlete's athletic ability coefficient measured in advance, and viewing that gives the same exercise load from the athlete's exercise intensity. The player's actual exercise intensity is calculated, and the means of giving fatigue level is controlled so that the viewer is fatigued with the actual exercise intensity, so the athlete's feeling of fatigue, difficulty, and pain during the competition match. You can experience it as a viewer's own movement.
