Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Human motion in general, that is, basic motions such as walking, running, and swimming, or cooperative motions with an exercise tool such as throwing, kicking, and receiving a ball are recorded on a video and reproduced on a monitor. A visual training technique that allows a motor operator to visually recognize his / her form and improve the form. In particular, the present invention relates to visual training in swimming competitions, in which visual training has been difficult.

[0002]

2. Description of the Related Art Human athletic movement training covers basic movements such as exercise training for infants or exercise rehabilitation for handicapped persons, from learning advanced cooperative movements such as athlete's athletic movements. There are many things, even things.

[0003] In order to master the exercise in a short period of time, a practice method that appeals to the sight is considered effective. That is, the first step is to visually recognize one's own motion form using a mirror or a video even in baseball batting or golf swing practice.

For example, Japanese Patent Laid-Open No. 7-289676, "Analog waveform display control device and collection device" (Hitachi, Ltd.)
In practice, when practicing a golf swing, a user's own swing image and an analog waveform related to athletic motion such as an electromyogram are displayed in synchronism, and the self-form and the power distribution are recognized by looking at the synchronized image.

[0005] Following such self-awareness, the basic process of training would be to repeat the process of finding differences from the example by comparing it with the example form of an advanced person and improving it. That is, the process is “self-awareness” → “model comparison” → “difference discovery” → “improvement”.

[0006] The basic training process includes speed and gymnastics competitions such as track and field racing, walking, swimming, skiing, skating and cycling, animal racing such as horse racing and dog racing, and speed racing athletes using vehicles such as cars and motorcycles. Training and ball games such as baseball and golf.

In any case, for the first half of the basic training process, "self-awareness" and "model comparison", a practice method that appeals to the sight using a mirror, a photograph or a video is effective.

[0008] Furthermore, in training, "presentation of results" of training, such as "existence of a race opponent" and records during training, is a great encouragement. This encouragement can also be visually provided to the trainee by the numerical value of the record or the like.

[0009] For example, Japanese Patent Application Laid-Open No. Hei 8-1 for bicycles
41127 "Bicycle competition simulation device" (Matsushita Electric Works), JP-A-7-250919 "Cycling simulation system" (Matsushita Electric Works), Japanese Patent Publication 6-7
873 "Training bicycle device" (Mitsuno).

[0010] These are images of statues and scenes of virtual "competitors" for cycling or cycling.
It is displayed visually to the trainee in synchronization with the operation status of the training bicycle with the idling roller. That encourages training.

However, in swimming and swimming, such visual training has not been carried out very much. The reason is that the swimmer wears goggles or the like and has a certain level of vision in the water, but has a narrow field of view. In addition, he is unable to respond to visual information because he concentrates his attention on breathing. In addition, displaying images in water is not easy.

In such a situation, Japanese Patent Laid-Open Publication No. Hei 8-1
There has been proposed a device such as 73587 "Display system for swimming competition" (Seiko Denshi) which displays the swimming distance and the lap time in the middle of a long-distance race underwater for the convenience of the swimmer.

[0013] However, the visual training process of “self-awareness” and “model comparison” for the swimmer is effectively performed, and the existence of the “competitor” is made conscious, and the difference in the record with the competitor is presented. Encouraging training was not possible with conventional technology. The present invention makes this possible.

In recent years, communication technology, especially internet technology, has been developed and spread. 2. Description of the Related Art A remote competition (telecompetition) has been proposed in which a home and a game center, homes and game centers are connected to each other using the Internet, and the same game is virtually performed between competitors at communication points separated from each other.

[0015] Regarding the remote competition, see JP-A-7-2034.
54 "Race-type game and multi-player type game system using the same" (NAMCO).

However, such a remote competition is not a virtual game, but is applied to a competition in which a competitor actually performs an athletic movement, or a remote competition is used to encourage a trainee. (To provide an incentive) has not been proposed before. In particular, the present invention enables a remote swimming competition and provides an effective training technique using the swimming.

[0017]

According to the present invention, a moving image of a swimmer during swimming is photographed by a photographing system as shown in FIG. 3 in the figure is a video camera, 4 is a videotape for analog,
For digital, it is a removable small-capacity image data recording medium such as a floppy disk, magneto-optical disk, or flash memory card. The fact that 4 is indicated by a dotted line indicates that it is not essential.

In FIG. 1, reference numeral 5 denotes a fixed large-capacity image data recording medium and a recording device, and reference numeral 6 denotes an image reproducing device and a communication network terminal (Internet terminal). Reference numeral 10 denotes an image monitor. Reference numeral 6 excluding the communication function is referred to as a “synchronous playback device” of an image, and reference numeral 5 excluding a recording medium is referred to as a “moving image recording device”.

According to the above definition, the present invention provides a "moving image recording apparatus" for storing moving image data of athletic motion in a storage medium.
And a "synchronous playback device" that displays moving images on the monitor screen
It is characterized by having: A further feature is that a “time timing cue” is added to the moving image data.

The time timing queue is 1 in FIG. In the case of swimming, 1 is the start time of the competition. This applies to other track and field races, walking, skiing, skating, cycling, horse racing, dog racing, automobiles, motorcycles, and the like.

As shown in FIG. 2, the time timing queue 1
Is stored in the first storage location of the image frame data of the moving image. Subsequently, moving images of a series of competitions are recorded as image frames. Therefore, if a moving image of the same game to which 1 has been added is added, when the 1 is added at the time of reproduction, a reproduced image virtually played simultaneously can be obtained.

Even if there is a difference in the recording period of the moving image, that is, how many frames are recorded in one second, the difference may be corrected. For example, if there are a moving image of 12 frames / second and a moving image of 6 frames / second, the former is played back by half of every two frames,
Second frames may be copied and reproduced synchronously at 12 frames / second. Similar correction is easy even if there is a difference in other recording periods.

2 in FIG. 2 is the image frame data of the goal touch described for the purpose of explanation, and the horizontal axis of the figure is the time axis.
The image data is data of the same sporting event, and indicates from 1 indicating a start time to a goal image 2 on a unified time axis after the above-described recording cycle correction.

In FIG. 2, the shortest time 30 is the moving image data during the competition when the world record is established, 31 is the moving image data during the competition when the Japan (domestic) record is established, and 32 is the competition when the best record is established. This is the moving image data in the middle.

Here, it is assumed that the swimmer performs the same competition as in FIG. 2 in training or racing, and shoots a video using the present system. Then, 33 to which the time timing queue 1 is added is recorded.

FIG. 3 shows an example of an image reproduced on the monitor 10, which shows 32 self-best images 40 and 33 current images 41.
It is a comparison image with. As shown in this figure, at the same time, that is, at 1:01:09 after the start, a comparison between the form at the time of personal best and the present form, and the movement deviation due to the difference in the pitch of the stroke (a series of repetitive movements of the limbs) are apparent at a glance. You can recognize yourself.

The higher the level of swimmers, the more self-awareness of such form and pitch of strokes is important in training. The operation deviation due to the pitch difference can be more accurately understood if one image is reproduced forward and backward by frame.

Specifically, as shown in FIG.
The same stroke state occurs in the image 42 of 1 minute 09 seconds 59 sent five seconds ahead. Therefore, in this competition 33, 1
It can be seen that there was a 0.5 second stroke movement delay in swimming per minute 09 seconds.

Further, the present system makes it possible to make an important "model comparison" in training. That is, as shown in FIG. 5, the difference between the form and the stroke at the same time after the start of the world record swimmer and himself / herself can be understood. The image on the right in FIG. 5 is an image when WR (world record) is established.

The fact that a competition image with an international-level player can be seen virtually even in the case of "comparison of examples"
More than that, it is a good stimulus to the players and the training effect is improved.

Further, in the present invention, it is possible to learn not only the general swimming form as described in the swimming instruction book, but also the "style" of the swimming that changes little by little from the start to the finish. More specifically, the style is the difference in pitch, the distribution of the pace, and how the race runs. This is especially important for long-distance races, but it has been difficult to learn in the past.

In the present invention, even at long distances, images of excellent swimmers at arbitrary distances can be compared with images of their own form in images as shown in FIGS. It is easy to decipher the difference in pitch, pace distribution, and the timing of the race in the middle of a long distance race. Moreover, since you can see it after you swim the same distance during training, you can immediately reflect on your next self-improvement and the training effect is outstanding.

In FIGS. 3 to 5, one monitor screen is a multi-screen monitor for displaying a plurality of images. However, as shown in FIG. 6, a plurality of single image monitors 10A may be arranged.

FIG. 7 is a diagram relating to a remote competition (telecompetition). Reference numerals 7A, 7B, and 7C denote communication network terminal connection portions of the stadium A, the stadium B, and the stadium C, respectively. This is called a "hub" on the Internet. Reference numeral 8 denotes a part of the communication network.

A moving image recording apparatus 5 is connected to a communication network terminal 6 (also an image synchronous reproduction apparatus), and a moving picture of a movement with a time timing cue added from a communication point separated via a communication network 8. Receive image data. This allows a "virtual competition" to be performed at a different place and time, compared to a game that was conventionally performed at the same time and place.

That is, the stadium B receives the competition image with the time timing and cue performed on the previous day at the stadium A, and the real-time competition of the stadium B and the competitor of the stadium A can perform a virtual competition.

Still further, as long as the start time timings are matched, any athlete member can play the virtual competition image at any time, which is convenient.

With this system, it is possible to practice virtually simultaneously with overseas trainees using the international nature of the Internet. There is a time difference abroad, but with this system there is no problem even if you do not compete at the same time, it is only necessary to synchronize the timing. These international practice exercises are a great encouragement for monotonous and demanding trainees.

BEST MODE FOR CARRYING OUT THE INVENTION

Particularly in swimming training, an image monitor for a swimmer is preferably provided for each course of the pool so that the swimmer on the course can observe the monitor image. This is shown in FIG. It may be preferable to place a monitor near the starting platform as shown.

For example, in a repetitive practice such as interval training, it is preferable that the swimmer visually recognize his or her own swimming style on the monitor screen during the repetitive rest time and reflect it in the next repetition.

【Example】

The swimming pool is a harsh environment for a monitor with built-in electronic components. In addition to water intrusion, the temperature of the outdoor pool in summer is over 50 degrees Celsius, so cooling that is waterproof is essential.

Therefore, as shown in FIG. 8, a water cooling pipe 14 is connected from a water tap 11 at a poolside to a water tank 12.
May be attached to the water-cooled casing 13 of the monitor 10 and circulated or drained to a pool.

By the way, as shown in FIG. 8, it is inconvenient for a swimmer to lean to the floor level by the pool to view the monitor image of the pool. If there is a monitor near the surface of the pool, it is convenient because you do not need to embark. However, it is difficult to install a monitor near the surface of the water because of the risk of water intrusion.

Therefore, an optical system for shifting the image light of the monitor to near the water surface level of the pool is added to the monitor.
The optical system may be any optical waveguide made of an optical fiber.

Further, a periscope optical system 15 using a combination of a prism that refracts light as shown in FIG. 9 or a mirror that reflects light may be used. 17 and 18 in the figure are the poolside and water surface levels, respectively.

Further, a part of the housing of the periscope optical system is
When the folding means which can be extended and contracted is provided, it does not hinder the turning operation. This is shown in FIG. This has a bellows-type folding mechanism 19 attached to the optical system 15. 20 refracts the monitor image real image light at the poolside level,
This shows a virtual image formed by reflection.

[0047]

As described above, the visual training process in which the swimmer performs "self-recognition" and "model comparison" of the form can be easily performed. Even if they are separated from each other, even if they are not at the same time, it is possible to encourage the training by making them aware of the existence of the competitor in the "remote competition" and comparing and recognizing the difference from the competitor with images.

The system of the present invention is not limited to swimming, but is applicable to general human athletic movement training. In other words, there are many applications, from those that learn advanced cooperative movements such as athlete's athletic movements to those that are aimed at basic movements such as exercise training for young children or exercise rehabilitation for handicapped persons.
