Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bodily sensation relay device, and more particularly, to a bodily sensation that allows a player who is actually competing, such as a marathon, boat race, or bicycle race, to experience the movement as a viewer's own movement. It relates to a competition relay device.

[0002]

2. Description of the Related Art At present, there are two methods of enjoying sports, namely, "competition using one's own body" and "watching a competition performed by another person". The former method of “competing using one's own body” is a way to directly experience the enjoyment of sports by actually playing the sports.

On the other hand, the latter case of "watching a game performed by another person" is a method of indirectly enjoying a sport through watching a game. The latter can be further classified into two types: watching at a venue where a competition is being held, and watching at a remote place, such as sports broadcasting such as TV broadcasting. The biggest attraction of watching games at the venue is to go directly to the venue and experience the atmosphere of the venue, and the most attractive point is that you can watch sports broadcasts that are traditionally broadcasted while staying at a remote location . In recent relays, more detailed relays are performed by adding various types of additional information to images and live broadcasts.

[0004]

However, since all of the methods are based on watching the game from an objective viewpoint of a third party,
Even if the excitement and appearance of the venue can be conveyed, it is difficult to convey the feelings of the competitors and the pleasure of playing sports.

[0005] Therefore, a main object of the present invention is to provide a bodily sensation relay device that allows a viewer to experience the bodily sensation of a real athlete playing sports.

[0006]

The invention according to claim 1 is
A relay system for detecting a degree of fatigue of an athlete and providing the viewer with the detected fatigue, the fatigue level detecting means for detecting the degree of fatigue of the athlete, and transmitting information on the detected degree of fatigue. A transmitting unit, a receiving unit that receives the transmitted fatigue level information, a fatigue providing unit for giving the viewer fatigue, and a control unit that controls the fatigue providing unit based on the received fatigue level information. It is composed.

[0007] The invention according to claim 2 further comprises a competition environment detecting means for detecting a competition environment of the competitor, a competition experience means for experiencing the same competition as the competitor, and a competition detected by the competition environment detection means. Means for transmitting environmental information;
A means for receiving the transmitted competition environment information and a means for controlling the competition experience means based on the received competition environment information are included.

[0008] In the invention according to claim 3, the fatigue level detecting means according to claim 1 detects at least one of body temperature, heart rate, breathing and sweating of the competitor.

In the invention according to claim 4, the fatigue imparting means according to claim 1 changes a game pitch.

According to a fifth aspect of the present invention, the fatigue imparting means of the first aspect detects at least one of wind, temperature, humidity, atmospheric pressure, and oxygen concentration.

[0011] In the invention according to claim 6, the competitor is a marathon runner, and the competition experience means includes a treadmill on which the viewer runs.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an immersion game relay device according to an embodiment of the present invention is provided in which a viewer watches a game from a player's standpoint, so that the viewer can experience the actual state of the game up close.
At the same time, they try to feel the excitement and excitement unique to the players. As a result, the viewer can experience the excitement and excitement peculiar to the competitor as if he were at the competition venue from the position of the target competitor.

Here, in the following description, all senses of the athlete that the viewer experiences as a player's position are collectively defined as "broad field of view". For example, the feeling of running, the tension of the game, and the like. The main examples are the sensations of the body (movement, balance, acceleration, fatigue, etc.), the "view in a narrow sense" seen around, and the sounds heard around. However, athletes' “broad perspective” varies depending on the type of sport. In the following description, a case will be described in which the present invention is applied to a marathon in which reproduction of a “broad field of view” is relatively easy.

Table 1 shows an example of the "view in a broad sense" felt by an athlete who is actually running and presenting the view to a remote viewer.

[0015]

[Table 1]

FIG. 1 is a block diagram showing the overall configuration of an embodiment for realizing the above-mentioned physical experience relay device.

In FIG. 1, the sensation sports relay device includes an information acquisition device 3 and a relay device 4 that are worn by an athlete 2 in a stadium 1.
And a playback device 6 installed in the home 5. The communication between the information acquisition device 3 and the relay device 4 is performed through short-range wireless communication, and the communication between the relay device 4 and the reproduction device 6 is realized by ordinary TV broadcasting.

The information acquisition device 3 includes a microphone 31 for collecting surrounding sounds and a video camera 3 for capturing surrounding scenery.
2, a weather sensor 33 for measuring weather information such as temperature, humidity, wind direction and wind speed, a physical condition sensor 34 for detecting physical condition such as heart rate, respiratory temperature, and perspiration, and data transmission for transmitting information obtained by these. Machine 35. The microphone 31, the video camera 32, and the weather sensor 33 constitute a competition environment detecting means, and can be mounted together with the data transmitter 35 on a hat worn by the competitor. The physical condition sensor 34 constitutes a degree of fatigue detection means, and is attached to the chest, neck, wrist, or the like of the competitor. The transmission of various information from the data transmitter 35 can be variously conceived, such as a time division method. Such an information acquisition device 3 is worn by all competitors whose viewers want the physical experience.

The information acquired by the information acquiring 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 acquiring device 3. A tracking image captured by the relay vehicle from behind the athlete 2 (not shown) is also transmitted to the relay device 4, and the information extraction device 42 extracts the visual field information sent from each athlete and transmits them to the broadcasting device. The data is converted into a format that can be transmitted by TV broadcast radio waves by 43 and broadcast to each home.

On the other hand, the playback device 6 of 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 the TV broadcast from the relay device 4, and the visual field information is provided to the decoding device 72. The viewer can select the visual field information of the competitor of interest by 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.

Here, the competition experience means includes a treadmill 9 on which the viewer 8 rides and runs, and a monitor display 10 for displaying surrounding images based on image information.
And a speaker 11 for reproducing surrounding sounds, a blower 12 for sending a head wind, and an air conditioner 13 for applying a predetermined temperature and humidity. In addition, the load on the treadmill 9 is increased, the headwind from the blower 12 is increased, and the temperature and humidity of the air conditioner 13 increase the viewer 8.
Can provide fatigue, and these constitute a fatigue imparting means.

If another headwind device is installed behind the viewer 8, a tailwind can be given to the viewer 8, and in this case, fatigue of the viewer 8 can be reduced.

Further, in the case where mountain climbing is assumed by inclining the treadmill 9 without limiting to a marathon, the viewer can be tired by changing the air pressure and the oxygen concentration.

The viewer 8 has a physical condition sensor 14 on his chest or the like.
And run. Information from the physical condition sensor 14 is transmitted to the user monitor 74 via the data transmitter 15 attached to the cap worn by the viewer 8. Also,
The running state and physiological state of the viewer 8 are captured by the monitor video camera 16 and provided to the user monitor 74.

Therefore, according to this embodiment, the monitor display 10 displays an image of the field of view that can be seen around the player 2, and the monitor speaker 11 emits sounds that can be heard around the player 2. It is reproduced as a stereo sound, and the wind direction and the wind of the wind estimated from the running speed of the competitor 2 and the wind condition of the stadium are sent from the blower 12. Further, weather conditions of the same temperature and humidity as those of the stadium 1 are given from the air conditioner 13.

As a result, the viewer 8 can experience the excitement and excitement inherent in the athlete 2 running in the stadium 1 at home.

In the embodiment shown in FIG. 1, the sound is detected by the microphone 31 and the image of the visual field is detected by the video camera 3.
2, the weather information is detected by the weather sensor 33, and the physiological information is detected by the physical condition sensor 34, but any of those widely known can be used. However, the running speed of the player 2 is difficult with the existing method.

Therefore, in the embodiment of the present invention, attention is paid to a phenomenon that the traveling speed during traveling is inversely proportional to the pitch, and the traveling speed is estimated from the pitch information. Here, the pitch is a cycle in which the foot alternately touches the ground during running. In particular, in this embodiment, the pitch is measured from the image information, which is one of the visual field information of the athlete 2, without using a separate sensor for directly measuring the pitch. This reduces the number of sensors worn by the athlete 2, thereby improving the athlete's feeling of wearing the device and reducing the amount of transmitted information.

FIG. 2 is a flowchart showing a running speed measurement algorithm according to an embodiment of the present invention, and FIG. 3 is a view showing an image frame for measuring the running speed.

An image (FIG. 2A) obtained from the video camera 32 mounted on the athlete 2 vibrates up and down with the running operation. First, the state of the vibration is obtained between the frames constituting the video signal by the image processing.
As shown in FIG. 3A, here, it is checked 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, a horizontal movement component dx and a vertical movement component dy are obtained, but only the vertical movement component dx is used as vibration information in this frame. Thereby, even if the competitor 2 sees an arbitrary direction during the running, it does not affect the information on the vertical movement during the running, so that the stable vibration information can be searched.

When the FFT filter is applied to the time-series vibration information (FIG. 2 (b)) obtained as described above, the spectrum (FIG. 2 (c)) can be used within the range of the human running pitch. Is obtained as the pitch. Note that the pitch determined in this procedure is a discrete value, and the estimated running speed obtained from the running characteristics of the player 2 from the discrete value pitch is also a discrete value. If the speed obtained by the discrete value pitch is reproduced on the treadmill 9 as it is, even a slight change in pitch causes a sudden change in speed, which is dangerous. For this reason, it is necessary to change the pitch continuously. In this case, a continuous value (FIG. 2D) is obtained by using spline interpolation.

According to the above procedure, the estimated traveling speed from the video (FIG. 2E) is continuously obtained, but the speed calculation processing is delayed by several seconds with respect to the video due to the acquisition of the FFT data. This can be solved by a process of delaying the video in the relay device 4 at the time of relaying.

As an example of measuring the running pitch, a method of measuring a broadcast image of a normal broadcast by image processing has already been proposed. However, any of these methods requires an initial setting, and the photographing conditions which change every moment. In the case where is changed, it is necessary to perform the initial setting again and the like, but in this embodiment, such initial setting becomes unnecessary.

By the way, since the sports athlete performs reinforced training exclusively, if the amount of exercise of the athlete 2 is reproduced on the body of the viewer 8 as it is, the physical burden (fatigue) compared with the athlete 2 ) May increase. Therefore, it is required to implement a function for providing an experience tailored to the viewer 8. In order to realize this, in the embodiment of the present invention, the reproduction of the exercise amount is adjusted by comparing the sweating and the heart rate of the athlete 2 and the viewer 8.

FIG. 4 is a block diagram showing the operation of adjusting the reproduction of the momentum. As shown in FIG. 1, the playback device 6 is provided with a monitor video camera 16 for capturing the running state of the viewer 8 and a physical condition sensor 14 for detecting a physiological state. Based on the image output of the video camera 16, the running position and running pitch information of the viewer 8 on the treadmill 9 are measured. This measurement is performed by the user monitor 74 of FIG. Specifically, for example, Japanese Patent No. 2923493
As proposed in the above issue, the position of the toe of the viewer 8 is detected, and based on the detected position of the toe, the stance time from when the toe lands on the walking surface to when the toe leaves is measured. The pedestrian's running speed based on the pedestrian is detected.

The physical condition sensor 14 constantly measures the fatigue caused by the running motion of the viewer 8. On the other hand, the sensation presentation device driving system 73 shown in FIG.
And a scale conversion mechanism for the traveling speed. The state comparison mechanism 731 determines the running state, heart rate,
It monitors physical condition information such as breathing, and compares the information with the running state and physical condition information of the viewer 8. The state comparison mechanism 731 has registered therein personal information such as the age and the athletic ability of the viewer 8, and refers to the registered information while referring to the running load scale conversion mechanism 7.
At 32, the scale conversion of the running load presented by the treadmill 9 is performed. Thereby, the degree of fatigue of the viewer 8 can be reduced or increased. Of course, when the viewer 8 detects a dangerous state such as a fall or an excessively fatigued state, the viewer 8 is immediately advised and the treadmill 9 is stopped.

In the above embodiment, the present invention has been described with respect to an example in which the competitor 2 is a marathon runner and the viewer 8 runs on the treadmill 9. However, the present invention is not limited to this. In the case of cycling or boating, the viewer 8 can obtain the same physical experience as the player 2 by using a rowing machine or an ergometer instead of the treadmill 9.

Further, in the embodiment shown in FIG. 1, the surroundings and images are acquired by the information acquisition device 3 by the microphone 31 and the video camera 32 in the stadium 1, and they are displayed by the monitor 5 and the speaker 11 in the home 5.
But it is not limited to this.
May be controlled so as to give the viewer 8 the same fatigue as the competitor 2.

In a more preferred embodiment of the present invention, the degree of fatigue of the viewer is also detected, and the fatigue imparting means is controlled in consideration of the degree of fatigue.

Further, more preferably, the fatigue imparting means is controlled in consideration of the personal information of the viewer.

Further, in a more preferred embodiment, the walking speed is determined by measuring the standing time from when the viewer's toe lands on the walking surface until the viewer separates, and the speed of the treadmill is calculated based on the walking speed. Adjusted.

It should be noted that the embodiment disclosed this time is an example in all respects and is 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.

[0043]

As described above, according to the present invention, the fatigue level of an athlete is detected, the detected fatigue level information is transmitted, and the fatigue level information is received to reduce fatigue of the subject. Since it is provided, for example, at home, the viewer can play the game while having the same experience as the player who is playing in the stadium.
