Japanese Patent Laid-Open No. 10-309335

  For example, let us consider a case where a motion is described using a moving image of a swimmer.

In the case of using a live-action photograph, there are places where the subject person becomes unclear due to fluctuations caused by waves on the water surface and refraction of light in the water. As a result, it was difficult to understand the movement, and it was particularly difficult to explain to children.
In one aspect, an object of the present invention is to make it easier for a third party to understand the movement of a swimmer during swimming.

  In order to achieve the above object, the disclosed playback device is provided. This playback device includes a storage unit for storing animation videos formed by drawing that simultaneously illustrates the postures of swimmers above and below the surface of the water at the location where the main points of movement during swimming are extracted, and an animation movie And a reproduction unit capable of repetitive reproduction.

  In one aspect, a third person can easily understand the movement of a swimmer during swimming.

It is a figure which shows the tablet terminal device of embodiment. It is a figure explaining a moving image. It is a figure explaining a moving image. It is a figure which shows the hardware constitutions of the tablet terminal device of embodiment.

Hereinafter, a tablet terminal device according to an embodiment will be described in detail with reference to the drawings.
<First Embodiment>
FIG. 1 is a diagram illustrating a tablet terminal device according to an embodiment.
The tablet terminal device (computer) 1 according to the embodiment is a device operated by an instructor at a swimming school, for example.
The tablet terminal device 1 has a waterproof function and can be installed on the pool side.
The tablet terminal device 1 includes a storage unit 2 and an application execution unit 3.

  The storage unit 2 can be realized by a data storage area provided in a RAM (Random Access Memory), an SSD (Solid State Disk Drive), or the like included in the tablet terminal device 1.

  Moreover, the application execution part 3 is realizable with the function with which CPU (Central Processing Unit) which the tablet terminal device 1 has is provided.

  The storage unit 2 stores in advance one or more animation moving image files indicating the swimming method. This animation is not a live-action image, but an animation of a drawing in which the points that are the main points of movement during swimming are illustrated. Therefore, it can be reproduced as a moving image or a single illustration (still image). In addition, a certain number of drawings are secured so that the swimmer does not move unnaturally when played back as a moving image.

In the application execution unit 3, the moving image stored in the storage unit 2 is reproduced and displayed on the display of the tablet terminal device 1 in accordance with the operation of the instructor. Moreover, the application execution part 3 changes the reproduction speed of an animation according to a leader's operation.
Examples of cases in which this moving image file is used include a case where the instructor first shows the student to swim, or a case where the instructor points out the fault of the student.
2 and 3 are diagrams for explaining a moving image.

  The moving images shown in FIG. 2 and FIG. 3 are moving images explaining forward breathing of breaststroke. 2 and 3, functions used for reproducing a moving image, such as an operation reproduction button and a volume, are not shown.

  As shown in FIG. 2, the drawing showing the swimmer's motion is sequentially reproduced from the first motion of breaststroke. In each drawing, parts that are not considered important for explanation of the action such as splashing are omitted so that the characteristic part of swimming can be easily understood. Of course, it is drawn about the part that needs to explain the movement of water.

In this movie, the operation of scratching water once and breathing once is watched twice in one playback. Thereby, for example, the instructor can execute the action of showing the second time for confirmation after explaining the operation at the first time by one reproduction. Moreover, even if a student misses an operation | movement by the 1st reproduction | regeneration, a swimmer's movement can be confirmed by the 2nd reproduction | regeneration. In addition, there is a slight gap between the first reproduction and the second reproduction. Thereby, it can be easily grasped that the second reproduction is started.
A one scene of a moving image is displayed on the display 4 shown in FIG. Mainly the upper body movements are close-up.

  The display 4 displays the surface of the swimmer and the action in the water. In the case of live action, it is difficult to display the posture of the swimmer above and below the surface of the water at the same time due to the wave of the water and the refraction of the light in the water, but this video is an animation of the drawing, The posture of the swimmer above and below the water surface can be displayed simultaneously on the screen in an easy-to-understand manner. For example, in the example shown in FIG. 3, it can be easily grasped that the elbow and the shoulder are on the water surface. In addition, it is possible to easily grasp the position and position of the hand below the surface of the water. In addition, since the moving picture shown in FIG. 3 is for explaining the operation of the upper body, the lower body is not moving. In the case of a live-action shot, it may be difficult to maintain a model position for shooting, but in a drawing animation, the ideal position can be easily maintained by drawing.

  When the instructor plays a video when teaching a student, the instructor can switch to an arbitrary playback speed. For example, for the first student, the video is played at a slow speed. In addition, for students who have become more proficient, videos are played at normal speed. The necessary points of movement are illustrated, so you can add explanations as stop motions at the point where it becomes a point, and it is easy for children to understand with the point.

  Also, by showing the video before swimming, there is an advantage that students can easily grasp the image of swimming. This is particularly effective at a beginner level where the image of swimming is not made.

In addition, by repeatedly playing the moving image, the moving image can be repeatedly shown to the students. Thereby, for example, by installing the tablet terminal device 1 in the repeat playback state near the practice place and practicing, it is possible to continue showing the video to the student while waiting for the turn even during the practice.
In addition, since the tablet terminal device 1 has a waterproof function, it can be brought not only into the pool side but also into the pool to show a moving image.

  In addition, in the case of an unstable and fast moving event such as underwater or in the air, there may be a case where blurring occurs even in slow playback in live-action and the visibility is poor. Since the moving image is an animation of drawing, even if it is slow-played, there is no blurring, and the points when swimming can be illustrated.

  In addition, when the instructor himself / herself shows a sample, it is extremely difficult to explain in words while swimming, but the instructor can explain points simultaneously while showing a video on the tablet terminal device 1.

  In addition, when the instructor himself / herself shows a sample in the water, the student must try to dive in the water, but in the case of the tablet, the student can show a sample of the underwater movement even if the student does not dive. In the present embodiment, a moving image when viewed from the water is illustrated, but a moving image when viewed from the water can be easily created and stored in the storage unit 2.

The tablet terminal device 1 also has a moving image shooting function using a camera. Using the video shooting function, students can watch their own swim as they swim, making it easy to correct self-image and actual swim. In addition, since the instructor only has to tell what is different from the video that was shown once, the instructions are easy to be specific, and the student can be understood.
Using the video shooting function of the tablet terminal device 1, the student can check the progress of swimming.

In addition, since the animation moving image is formed of a plurality of still images, it can also be used as a still image. In this case, there is an advantage that an image having no blur can be displayed on the display 4 as compared with a real image.
Next, a hardware configuration of the tablet terminal device according to the embodiment will be described.
FIG. 4 is a diagram illustrating a hardware configuration of the tablet terminal device according to the embodiment.

The tablet terminal device 1 according to the second embodiment has a point selection mode and a point zoom mode.

  In the point selection mode, the application execution unit 3 displays a point selection button on the display 4 together with the animation movie when reproducing the animation movie.

  When playing an animated movie, for example, at a point where the leader thinks that an important point in the swimming movement (for example, a posture of a part of the body, etc.) Touch the corresponding part of the displayed animation with your finger.

Then, the application execution unit 3 associates the playback time (for example, “9.1 seconds from the start of animation”) with which the location is touched with the touched location (for example, absolute coordinates in animation drawing). Information is created and stored in the storage unit 2 in association with the animation movie.
In the point zoom mode, the application execution unit 3 displays an image captured by the camera 106 on the display 4.

For example, when an instructor touches an arbitrary part of the display 4, the application execution unit 3 temporarily stores an image captured by the camera 106 and displays the image on the display 4 in a still image state. The animation drawing is also displayed on the display 4 based on the point information stored in.
The application execution unit 3 zooms the portion touched by the instructor and compares it with the corresponding portion of the animation drawing.
In addition, instead of illuminating, each of them may be displayed on two screens.

  As described above, the tablet terminal device 1 according to the second embodiment detects and zooms at a point where the tablet terminal device 1 automatically zooms, not by the instructor (photographer). This allows students to visually understand the differences between the two.
