Embodiments for Carrying Out the Invention

[0012] Hereinafter, embodiments for carrying out the present technology will be described. The description will be made in the following order. 1. Overview of the entertainment pool system 2. First Embodiment (Example of a personal flowing pool) 3. Second Embodiment (Example of a normal swimming pool) 4. Third Embodiment (Example of a kids' pool) 5. Modification examples

[0013] <1. Overview of the Entertainment Pool System> FIG. 1 is a perspective view showing a configuration example of an entertainment pool system according to an embodiment of the present technology.

[0014] An entertainment pool system according to an embodiment of the present technology is a system that provides an entertaining pool by performing effects such as synchronizing the video of the content with the movement of the swimmer. For example, the entertainment pool system is installed in a leisure facility.

[0015] The entertainment pool system is composed of a pool 1, a display 2, and a control device (not shown).

[0016] As shown in FIG. 1, a plurality of displays 2 are provided on the outer side of the inner wall of the pool 1. For convenience of explanation, FIG. 1 shows a state in which a part of the inner wall of the pool 1 is broken, but in reality, inner walls that form the side surfaces and the front and rear surfaces are also provided at the broken part in the foreground, and the display 2 is provided so as to surround them.

[0017] The side surfaces (side walls) 11, the front and rear surfaces (end walls) 12, and the bottom surface (chassis) 13 that form the inner wall of the pool 1 are each composed of a transparent material such as reinforced acrylic. Touch sensors for detecting contact by the hands and feet of the swimmer are provided at desired positions on the inner wall. Based on the sensor data output by the touch sensors, it is detected that the swimmer has touched the inner wall.

[0018] On the outer side of the inner wall of the pool 1, a plurality of displays 2 are provided with their display surfaces facing the inside of the pool 1. The dashed-line frame shown on the inner wall of FIG. 1 indicates that the display of the display portion of the display 2 provided on the outside can be seen from inside the pool 1 through the inner wall.

[0019] In the example of FIG. 1, four displays 2 are provided side by side vertically and horizontally on the outside of the side surface 11, and two displays 2 are provided side by side vertically on the outside of the front and rear surfaces 12. On the outside (bottom) of the bottom surface 13, three displays 2 are provided side by side. The number of displays 2 provided on the outside of each surface can be appropriately changed according to the size of the pool 1.

[0020] The display 2 is a display device such as an LCD, an organic EL display, or an LED display. The display 2 displays the video of the content according to the control by the control device. The swimmer can view the video displayed on the display 2 from underwater. The display of the video of the content may be performed using a projector.

[0021] Note that the display 2 does not have to be provided on the outside of all the surfaces of the side surface 11, the front and rear surfaces 12, and the bottom surface 13, but may be provided on the outside of at least any one of the side surface 11, the front and rear surfaces 12, and the bottom surface 13. For example, it is possible to provide the display 2 only on the outside of the bottom surface 13, or it is possible to provide the display 2 on the outside of each of the side surface 11 and the bottom surface 13.

[0022] The control device is constituted by, for example, a PC provided in a management room near the pool 1. The control device may be realized by a portable terminal such as a tablet terminal or a smartphone. The control device and each display 2 are connected via wired communication or wireless communication of a predetermined standard. The control device plays the content and controls the display of the video on the display 2.

[0023] Around the pool 1, a camera for photographing the swimmer is also provided. The camera for photographing the swimmer may be provided above the water such as on the pool side or the ceiling surface of the leisure facility, or may be provided underwater.

[0024] Figure 2 is a diagram showing an example of the display of the video of the content. For convenience of explanation, in Figure 2, a pool 1 with a modified configuration such as the number of display stands of the display 2 is shown. Also, the illustration of the display 2 itself is omitted.

[0025] As shown in Figure 2, on the display 2, for example, a video representing the state of the sea with fish, rock fields, etc. is displayed. Instead of the same video being displayed on each display 2, a single video representing the state of the sea is displayed with the entire plurality of displays 2 as one display surface. By connecting the videos of each display 2, one video is constituted.

[0026] The video displayed on one display 2 provided outside the side surface 11 is enlarged and shown in Figure 3. The video is, for example, a moving image.

[0027] The swimmer in the pool 1 can experience the feeling of swimming in the sea by swimming while watching such a video. By displaying videos of famous diving spots, etc., the swimmer can experience snorkeling and diving without actually going to the sea.

[0028] Videos other than those representing the state of the sea, such as videos representing the state of the night sky or videos of aerial photographs of the city, may be displayed. By swimming in the pool 1 in a state where these videos are being displayed, the swimmer can obtain the feeling of swimming in the air as if.

[0029] <2. First Embodiment (Example of a Personal Flow Pool)> The entertainment pool system of the present technology can be applied, for example, to a flow pool. A flow pool is a pool in which the flow of water in the pool is controlled so that a swimmer can continue swimming without turning.

[0030] Figure 4 is a diagram showing a state where a swimmer U1 is swimming in a personal flow pool.

[0031] The configuration of the pool 1 shown in Fig. 4, which is a personal flowing water pool, is the same as the configuration described with reference to Fig. 2. The white arrow A1 in Fig. 4 represents the direction of water flow. A water outlet for generating water flow is provided at a position near the white arrow A1 on the front and rear surfaces 12.

[0032] The control device of the entertainment pool system detects the swimming speed of the swimmer U1 based on the image captured by the camera, and controls the water flow rate in the pool according to the detected speed.

[0033] For example, the control device controls the water flow speed so that the faster the speed of the swimmer U1, the faster the water flow (strengthen the water flow), and the slower the speed, the slower the water flow (weaken the water flow). A swimmer swimming against the water flow can continue to swim at almost the same position.

[0034] In addition, the control device controls the transition of the video displayed on the display 2 according to the swimming speed of the swimmer U1.

[0035] For example, the control device controls the transition speed of the content video so that the faster the speed of the swimmer U1, the faster the video transition, and the slower the speed, the slower the video transition. On the display 2, a video in which the state of the coastline changes according to the swimming speed of the swimmer U1 will be displayed.

[0036] By swimming in the pool 1 as described above, the swimmer U1 can obtain a feeling as if he is advancing in the sea even though he is actually continuing to swim at the same position in the pool 1.

[0037] ·Configuration of the control device Fig. 5 is a block diagram showing a functional configuration example of the control device 21. At least a part of the functional units shown in Fig. 5 is realized by a predetermined program being executed by the CPU of the PC constituting the control device 21.

[0038] As shown in FIG. 5, the control device 21 is composed of a content input unit 31, a motion detection unit 32, a content playback unit 33, a content storage unit 34, and a water flow rate control unit 35.

[0039] The content input unit 31 receives operations by users such as swimmers and administrators of the entertainment pool system. For example, using the content input unit 31, selection of the content to be played is performed. For the control device 21, for example, content of seas in various places is prepared. The user selects the content of the sea they like and then enters the pool 1 and starts swimming.

[0040] The content input unit 31 outputs operation information, which is information representing the content selected by the user, to the content playback unit 33.

[0041] The motion detection unit 32 detects the motion of the swimmer based on information such as an image captured by a camera provided around the pool 1 and sensor data output by a touch sensor provided on the inner wall of the pool 1. For example, the motion detection unit 32 detects that the swimmer has touched the inner wall as the motion of the swimmer based on the sensor data output by the touch sensor. The motion detection unit 32 has a swimming speed detection unit 51.

[0042] The swimming speed detection unit 51 detects the swimming speed as the motion of the swimmer by analyzing the image captured by the camera. Information representing the swimming speed of the swimmer detected by the swimming speed detection unit 51 is output to the content playback unit 33 and the water flow rate control unit 35.

[0043] The content playback unit 33 acquires the content selected by the user from the content storage unit 34 based on the operation information supplied from the content input unit 31 and plays it back. The content playback unit 33 outputs the video obtained by playing back the content to the display device 22 and causes it to be displayed. The display device 22 corresponds to the display 2 in FIG. 1.

[0044] The content playback unit 33 controls the display of the content video on the display device 22 according to the information supplied from the motion detection unit 32. As described above, the speed of video transition is controlled according to the swimming speed of the swimmer. In this way, the content playback unit 33 functions as a playback control unit that controls the playback of the content and the display of the video.

[0045] Also, the content playback unit 33 causes the sound obtained by playing the content to be output from the speaker 23. The output of the content sound is performed in accordance with the display of the video.

[0046] For example, the speaker 23 is constituted by an underwater speaker provided on the inner wall of the pool 1 or the like. The speaker 23 may be configured as a headset and worn on the swimmer's head.

[0047] The speaker 23 may be configured as a full-face type headphone worn on the swimmer's head. By using the full-face type headphone, it may be possible to talk to a person outside the pool 1.

[0048] The content storage unit 34 is constituted by a non-volatile memory, an HDD, or the like. The content storage unit 34 stores in advance content that can be selected by the user.

[0049] The water flow speed control unit 35 controls the water flow speed in the pool 1 as described above based on the information supplied from the swimming speed detection unit 51.

[0050] ·Operation of the control device With reference to the flowchart of FIG. 6, the processing of the control device 21 having the above configuration will be described.

[0051] In step S1, the content input unit 31 receives the selection of the main content by the user. For example, content expressing scenes such as a coral sea, a night sea, and a deep sea is selected by the user.

[0052] Hereinafter, among the content reproduced during swimming as appropriate, the content reproduced as the main content is referred to as the main content. The main content includes at least the data of the video to be displayed on each display 2.

[0053] Also, the content temporarily reproduced to perform an effect-based production is referred to as effect content. For example, the effect content includes the data of the video to be displayed superimposed on the video of the main content. The effect content may be reproduced together with the main content, or may be reproduced alone.

[0054] In step S2, the motion detection unit 32 detects that the swimmer has started swimming. In response to the swimmer starting to swim, the detection of the swimming speed and the like is started by the swimming speed detection unit 51. Also, the detection of the swimmer's motion is started by the motion detection unit 32. The information representing the swimmer's motion detected by the motion detection unit 32 is appropriately supplied to the content reproduction unit 33.

[0055] In step S3, the content reproduction unit 33 acquires the main content selected in step S1 from the content storage unit 34 and starts displaying the video of the main content.

[0056] In step S4, the water flow speed control unit 35 controls the water flow speed of the pool 1 according to the swimming speed of the swimmer detected by the swimming speed detection unit 51. Also, the content reproduction unit 33 controls the transition speed of the video of the main content.

[0057] In step S5, the content playback unit 33 determines whether a predetermined condition is satisfied. For example, when the swimmer touches the inner wall of pool 1, or when the distance the swimmer has swum reaches a predetermined distance, it is determined that the predetermined condition is satisfied. The distance the swimmer has swum is calculated by the motion detection unit 32 based on, for example, the speed at which the swimmer swims and the time elapsed while swimming.

[0058] If it is determined in step S5 that the predetermined condition is satisfied, then in step S6, the content playback unit 33 plays the effect content and causes the display device 22 to display the video of the effect content.

[0059] For example, when a video representing the sea is being displayed as the video of the main content, a video of the effect content such as sharks or whales popping out is displayed. At this time, the content playback unit 33 causes the speaker 23 to output a sound effect corresponding to the display of the effect content.

[0060] After the video of the effect content is displayed, the process proceeds to step S7. Even if it is determined in step S5 that the predetermined condition is not satisfied, the process of step S6 is skipped and the process proceeds to step S7.

[0061] In step S7, the content playback unit 33 determines whether the swimming has ended based on the motion of the swimmer detected by the motion detection unit 32. For example, when the swimmer emerges from the water, it is determined that the swimming has ended.

[0062] If it is determined in step S7 that the swimming has not ended, the process returns to step S4 and subsequent processing is performed. That is, until the swimming ends, the display of the video of the main content continues, and the video of the effect content is displayed as appropriate.

[0063] On the other hand, if it is determined in step S7 that the swimming has ended, the process ends.

[0064] By the above processing, while the swimmer is swimming, the video of the main content and the video of the content for effects are continuously displayed according to the movement of the swimmer. The swimmer can continue swimming without getting bored while watching the transitioning videos.

[0065] Note that the history of the distance the swimmer has swum may be managed by the control device 21 and presented to the swimmer. The presentation of the history is also performed using the display device 22 (display 2).

[0066] For example, when content including a video of the sea between "Ishigaki Island" and "Miyako Island" is used for playback, in response to the end of swimming, text such as "You swam up to here today between Ishigaki Island and Miyako Island" is displayed. Also, a map showing the positional relationship of each of the starting point "Ishigaki Island", the destination "Miyako Island", and the position corresponding to the cumulative distance the swimmer has swum is displayed.

[0067] By presenting such a history, it becomes possible to provide entertainment value for swimming a long distance.

[0068] <3. Second Embodiment (Example of a Normal Swimming Pool)> The entertainment pool system of this technology can be applied to, for example, a normal swimming pool.

[0069] The normal swimming pool referred to here is a pool without a water flow control function as described with reference to FIG. 4. A plurality of displays 2 are also provided outside the inner wall of the pool 1 which is a normal swimming pool.

[0070] FIG. 7 is a block diagram showing an example of the functional configuration of the control device 21. In FIG. 7, the same configurations as those of the control device 21 in FIG. 5 are denoted by the same reference numerals. Redundant explanations are appropriately omitted. The same applies to FIG. 10 described later.

[0071] The configuration of the control device 21 shown in FIG. 7 is different from the configuration described with reference to FIG. 5 in that the reciprocation detection unit 101 is provided in the motion detection unit 32 and the water flow rate control unit 35 is not provided.

[0072] The reciprocation detection unit 101 of the motion detection unit 32 detects that the swimmer has swum back and forth in the pool 1 based on the image captured by the camera, the sensor data output by the touch sensor, etc. The information indicating that the swimmer has reciprocated in the pool 1 detected by the reciprocation detection unit 101 is output to the content reproduction unit 33.

[0073] The content reproduction unit 33 controls the display of the content video on the display device 22 according to the information supplied from the motion detection unit 32. For example, every time the swimmer reciprocates in the pool 1, the content reproduction unit 33 switches the content to be reproduced. The content to be reproduced is switched from the content being reproduced to another content. Note that the transition speed of the content video may be controlled according to the swimming speed of the swimmer.

[0074] The processing of the control device 21 will be described with reference to the flowchart of FIG. 8.

[0075] The processing of steps S21 to S23 is the same as the processing of steps S1 to S3 in FIG. 6. That is, in response to the swimmer starting to swim, the display of the video of the main content selected by the user is started.

[0076] In step S24, the content reproduction unit 33 determines whether the swimmer has made one round trip in the pool 1 based on the information supplied from the reciprocation detection unit 101.

[0077] If it is determined in step S24 that the swimmer has made one round trip, in step S25, the content reproduction unit 33 switches the main content to be reproduced. For example, the main content to be reproduced is switched from the content representing the state of the coral sea to the content representing the night sky.

[0078] After the content to be regenerated is switched, the process proceeds to step S26. Even if it is determined in step S24 that the swimmer has not completed one round trip, the process of step S25 is skipped and the process proceeds to step S26.

[0079] The processes of steps S26 and S27 are the same as the processes of steps S5 and S6 in FIG. 6. That is, according to a predetermined condition, the video of the content for effect is displayed on the display device 22.

[0080] In step S28, the content playback unit 33 determines whether the swimming has ended.

[0081] If it is determined in step S28 that the swimming has not ended, the process returns to step S24 and the subsequent processes are performed. That is, until the swimming ends, every time the swimmer completes one round trip, the main content is switched. Also, appropriately, the video of the content for effect is displayed.

[0082] On the other hand, if it is determined in step S28 that the swimming has ended, the process ends.

[0083] Through the above processes, while the swimmer is swimming, every time the swimmer makes a round trip in the pool 1, the main content is switched and the video is displayed. The swimmer can continue swimming without getting bored while watching the video that is switched every time one round trip is completed.

[0084] <4. Third Embodiment (Example of a Kids' Pool)> The entertainment pool system of the present technology can be applied to, for example, a kids' pool. A kids' pool is a pool for children provided in a leisure facility or the like.

[0085] FIG. 9 is a diagram showing an example of video display in a kids' pool.

[0086] A display 2 is also provided on the outer side of the inner wall of the pool 1 in FIG. 9, which is a kids' pool. In the kids' pool, for example, an effect of a shallow sea is presented.

[0087] By playing content representing the state of a shallow sea, as shown in FIG. 9, a video representing the movement of objects of marine organisms in the shallow sea and the state of a rocky beach is displayed. A child as a swimmer can experience playing in the shallow sea.

[0088] FIG. 10 is a block diagram showing a functional configuration example of the control device 21.

[0089] The configuration of the control device 21 shown in FIG. 10 is different from the configuration described with reference to FIG. 5 in that a child position detection unit 151 is provided in the motion detection unit 32 instead of the swimming speed detection unit 51, and the water flow speed control unit 35 is not provided.

[0090] The child position detection unit 151 of the motion detection unit 32 detects the position of a child in the pool 1 based on an image captured by a camera. Contact of a child with the inner wall of the pool 1 is also appropriately detected by the motion detection unit 32.

[0091] Information representing contact of a child with the inner wall and information representing the position of the child, detected by the motion detection unit 32 including the child position detection unit 151, are output to the content reproduction unit 33.

[0092] The content reproduction unit 33 controls the display of the content video on the display device 22 according to the information supplied from the motion detection unit 32. For example, the content reproduction unit 33 controls the movement of the objects included in the content video according to the position of the child.

[0093] In addition, the content playback unit 33 controls the transition of the content video. For example, when the child touches the inner wall of the pool 1, the content playback unit 33 causes a video of a different scene of the sea, following the currently displayed sea scene, to be displayed. When the child touches the inner wall of the pool 1, a sea scene different from the currently displayed one may be displayed, or the types of objects such as plants and fish may be changed so that a sea scene with a changing season is displayed.

[0094] With reference to the flowchart of FIG. 11, the processing of the control device 21 will be described.

[0095] In step S41, the content input unit 31 receives the selection of the main content by the user.

[0096] In step S42, the content playback unit 33 acquires the main content selected in step S41 from the content storage unit 34 and starts displaying the video of the main content on the display device 22.

[0097] In step S43, the content playback unit 33 controls the movement of the objects included in the video of the main content according to the position of the child detected by the child position detection unit 151. For example, when the child approaches a school of fish included in the video as an object, the content playback unit 33 changes the movement of the object so that the school of fish escapes.

[0098] In step S44, the content playback unit 33 determines whether a predetermined condition is satisfied. For example, when the child touches the bottom surface 13 of the pool 1, it is determined that the predetermined condition is satisfied.

[0099] If it is determined in step S44 that the predetermined condition is satisfied, in step S45, the content playback unit 33 plays the effect content and causes the video of the effect content to be displayed on the display device 22.

[0100] For example, when a video showing the shallows of the sea is being displayed as the main content video, a video of the content for the effect where crabs come out from the rock shadow is displayed. At this time, the content playback unit 33 outputs a sound effect corresponding to the display of the content for the effect.

[0101] After the video of the content for the effect is displayed, the process proceeds to step S46. Even when it is determined in step S44 that the predetermined conditions are not satisfied, the process in step S45 is skipped and the process proceeds to step S46.

[0102] In step S46, the content playback unit 33 determines whether swimming has ended (whether the play in pool 1 has ended). For example, when the child gets out of pool 1, it is determined that swimming has ended.

[0103] If it is determined in step S46 that swimming has not ended, the process returns to step S43 and the subsequent processes are performed. That is, until swimming ends, the movement of the objects included in the video of the main content and the display of the video of the content for the effect are controlled according to the movement of the child.

[0104] On the other hand, if it is determined in step S46 that swimming has ended, the process ends.

[0105] Through the above processes, while the child is in pool 1, the video of the main content and the video of the content for the effect continue to be displayed according to the movement of the child. The child can experience playing in the sea or the like while seeing the objects that move according to his or her own movement.

[0106] Note that the picture of the fish drawn by the child may be captured as an image, and an effect may be performed in the entertainment pool system such that the fish drawn by the child swims along the inner wall of pool 1.

[0107] FIG. 12 is a diagram showing the flow of the effect where the fish drawn by the child swims.

[0108] As shown by arrow A11 in FIG. 12, the control device 21 captures the picture of the fish drawn by the child as an image. Then, as shown by arrow A12, the control device 21 causes the captured image to be displayed on the display 2 and performs an effect such that the picture of the fish is swimming in the water.

[0109] Note that an effect such as outputting a sound effect from the speaker 23 or recording a score may be performed by the entertainment pool system in response to the child touching an object such as a crab or a shell.

[0110] <5. Modification Example> · Regarding the system configuration In the above, the PC constituting the control device 21 is provided near the pool 1, but all or part of the functions of the control device 21 may be realized in a server device on the network.

[0111] FIG. 13 is a diagram showing another configuration example of the entertainment pool system.

[0112] The entertainment pool system shown in FIG. 13 is configured by connecting a server device 201 that performs video display, sound output, water flow rate control, etc. to each device such as the display 2 provided around the pools 1-1 to 1-3 via a network such as the Internet.

[0113] The server device 201 is provided with all or part of the configuration of the control device 21 described with reference to FIGS. 5, 7, or 10. In this way, it is possible to realize the functions of the control device 21 in the server device 201 provided outside the facility where the pool 1 is provided.

[0114] The distribution of the content for the pool 1 may be performed by the server device 201. In this case, the control device 21 that controls the video of each pool 1 receives and plays back the content distributed from the server device 201.

[0115] ·Variation of the personal flow pool FIG. 14 is a diagram showing a configuration example of a personal flow pool.

[0116] Among the configurations of the pool 1 shown in FIG. 14, the same configurations as those described with reference to FIG. 4 and the like are denoted by the same reference numerals. Redundant descriptions will be omitted as appropriate.

[0117] A display 2 is provided outside the bottom surface 13 of the pool 1 which is a personal flow pool. The dashed-line frame shown on the bottom surface 13 in FIG. 14 indicates that the display of the display 2 provided outside the bottom surface 13 can be seen from inside the pool 1.

[0118] The pool 1 shown in FIG. 14 is a flow pool in which the display 2 is provided outside not the entire bottom surface 13 but a part of the bottom surface 13. The display 2 may be provided outside the entire bottom surface 13.

[0119] As described above, the swimmer U1 continues to swim at the same position by swimming against the water flow. In other words, the swimmer U1 continues to swim while adjusting the speed and the like so as to stay at the same position without hitting the inner wall. In the pool 1, a position serving as a standard for continuing to swim without hitting the inner wall is set in advance as a basic position. The swimmer U1 can continue to stay at the same position by swimming, for example, near directly above the basic position set on the bottom surface 13 so that his / her head does not leave, that is, so that the basic position comes directly below his / her face.

[0120] In the example of FIG. 14, the display 2 is provided in a range including the basic position located near directly below the face of the swimmer U1 who is swimming without hitting the inner wall. A target T which is a mark representing the basic position is displayed on the display 2. In FIG. 14, the target T is represented by a circle, but it is possible to display marks of various shapes and patterns as targets so that the swimmer U1 can recognize the basic position.

[0121] By looking at the target T displayed on the display 2, the swimmer U1 can confirm the position where he / she is swimming.

[0122] FIG. 15 is a cross-sectional view showing an example of the internal configuration of a flowing water pool.

[0123] The bottom surface 13 is composed of a transparent member such as reinforced plastic or acrylic resin.

[0124] Below the bottom surface 13, a space 251 having a predetermined width is provided. The display 2 is provided at a position corresponding to the basic position within the space 251. In the example of FIG. 15, the display 2 is provided at a position closer to the front surface 12-1 with reference to the center of the bottom surface 13.

[0125] Also, below the bottom surface 13, a water channel in which devices such as a propeller 252 for generating a water flow are provided is formed by piping or the like. A discharge port is formed in the front surface 12-1 of the inner wall, and a discharge port is formed in the rear surface 12-2.

[0126] The water in the pool 1 is discharged from the discharge port provided in the rear surface 12-2 as shown by the white arrow A51, and after passing through a filtering device (not shown), it is returned into the pool 1 from the discharge port as shown by the white arrow A52. When water is discharged from the discharge port on the front surface 12-1, a water flow is generated in the pool 1.

[0127] For example, in the control device 21, based on an image captured by a camera provided around the pool 1, the position of the head of the swimmer U1 is detected. The display of the video on the display 2 is controlled according to the detected position of the head.

[0128] FIG. 16 is a diagram showing an example of control of the video of the content in the flowing water pool.

[0129] For example, as shown by arrow A61 on the left side of FIG. 16, when the position of swimmer U1 is shifted to the right with respect to the front, as shown on the right side of FIG. 16, using the video of the content, the presentation in the correct direction is performed. The correct direction is the direction from the shifted position of the user towards the position directly above the basic position.

[0130] FIG. 17 is a diagram showing an enlarged view of the video of the content.

[0131] For example, when the head of swimmer U1 is at the position directly above the basic position, on display 2, together with the video of the main content, target T is displayed as shown on the left side of FIG. 17.

[0132] When the position of swimmer U1 is shifted to the right, on display 2, as shown by the white arrow A62 on the right side of FIG. 17, a video in which a shark as an object attacks swimmer U1 towards the left is displayed, thereby performing the presentation in the correct direction.

[0133] Swimmer U1 can return to the position where he / she is swimming by moving to the left to avoid the shark. Every time the position is shifted, by presenting the correct direction through such a video, swimmer U1 can continue swimming while staying in the same position. Similarly, when the position of swimmer U1 is shifted in other directions, a video for guiding swimmer U1 in the direction opposite to the shifted direction is displayed by the movement of the object.

[0134] Note that instead of the shark, the presentation in the correct direction may be performed by other objects such as fish included in the video of the main content. For example, by performing control to change the swimming direction of the fish, the presentation in the correct direction is performed.

[0135] Here, with reference to the flowchart of FIG. 18, the processing of the control device 21 for presenting the correct direction using the video of the content will be described. Descriptions that overlap with the above-described explanations will be omitted as appropriate. Note that the configuration of the control device 21 is the same as the configuration shown in FIG. 5.

[0136] In step S101, the content input unit 31 receives the selection of the main content by the user.

[0137] In step S102, the motion detection unit 32 detects that the swimmer has started swimming. In response to the swimmer starting to swim, the detection of the swimming speed, etc. is started by the swimming speed detection unit 51. Also, based on the image captured by the camera provided around the pool 1, the detection of the position of the swimmer's head is started by the motion detection unit 32.

[0138] The processes of steps S103 and S104 are the same as the processes of steps S3 and S4 in FIG. 6. That is, the display of the video of the main content is started, and the flowing water speed and the video transition speed are controlled according to the swimming speed of the swimmer.

[0139] In step S105, the content playback unit 33 determines whether the position of the swimmer has deviated. For example, when the distance from the position directly above the basic position to the center position of the head is greater than or equal to a threshold distance, it is determined that the position of the swimmer has deviated.

[0140] If it is determined in step S105 that the position of the swimmer has deviated, in step S106, the content playback unit 33 plays the content for effect according to the position of the swimmer, and causes the video of the content for effect to be displayed on the display device 22.

[0141] For example, a video of the content for effect such as a shark attacking as described above is displayed. The content playback unit 33 outputs a sound effect from the speaker 23 in accordance with the display of the content for effect.

[0142] After the video of the content for the effect is displayed, the process proceeds to step S107. If it is determined in step S105 that the position of the swimmer is not misaligned, the process of step S106 is skipped and the process proceeds to step S107.

[0143] In step S107, it is determined whether the swimming has ended. Until it is determined in step S107 that the swimming has ended, the display of the video of the main content and the content for the effect continues.

[0144] Through the above processing, the control device 21 can guide the position of the swimmer U1 in the correct direction.

[0145] The swimmer U1 can adjust his own position while enjoying watching the video. If the correct direction is presented by an image of an arrow or the like, a sense of incongruity will occur when the image of the arrow is displayed together with the video in the sea, and the sense of immersion will be impaired, but it is possible to prevent such a situation. Of course, it is also possible to present the correct direction by an image of an arrow or the like.

[0146] In the above, it is assumed that whether the position of the swimmer is misaligned is determined based on the position of the swimmer's head, but it may be determined based on the positions of other parts such as the position of the hand, the position of the foot, and the position of the torso.

[0147] Also, although it is assumed that the display of the video for guiding the direction of the swimmer is performed in the flowing water pool, it may be performed in a normal pool that is not a flowing water pool.

[0148] ·Regarding the headset A communication unit that performs wireless communication with an external device such as the control device 21 may be provided in the headset worn by the swimmer. For example, a wireless communication module compliant with Bluetooth (registered trademark) is provided in the headset as the communication unit. Various data such as audio data is transmitted and received between the external device and the headset.

[0149] FIG. 19 is a diagram showing a configuration example of the headset.

[0150] The headset 261 as the speaker 23 is configured integrally with the snorkel 262 and the mask 263. A communication unit 264 is provided at the upper end portion of the snorkel 262 that is located above the water when swimming while wearing the headset 261.

[0151] Wireless communication by Bluetooth becomes unstable in water. By providing the communication unit 264 in a portion located above the water, it becomes possible to stabilize the wireless communication.

[0152] ·Regarding the detection of the swimmer's operation A touch sensor is provided on the inner wall of the pool 1, and the operation of the swimmer is detected by the touch sensor. However, it may be detected by analyzing an image captured by a camera. When it is detected based on the image that the swimmer's hand has approached the inner wall, the display of the content video is controlled as described above.

[0153] ·Projection using a projector The display of the content video may be performed using a projector. For example, the video is projected with the bottom surface 13 as the projection surface. In this case, the bottom surface 13 is made of an opaque material, not a transparent material.

[0154] ·Control of lighting The lighting provided on the inner wall or around Pool 1 may be controlled in accordance with the display of the video content. For example, when displaying a video of content depicting a sunset, the control device 21 controls the lighting to emit orange light. Also, when displaying a video of content depicting diving towards the bottom of the sea, the control device 21 controls the lighting to become darker according to the depth of the sea represented by the content.

[0155] · Control of Video The video of the content may be enlarged or reduced according to the water depth of Pool 1. For example, the deeper the water depth of Pool 1, the larger the video of the content is displayed.

[0156] The video of the content may be enlarged or reduced according to the depth at which the swimmer is swimming.

[0157] Also, the deeper the water depth of Pool 1, the slower the transition speed of the video of the content may be. By performing such display control, a video experience with less discomfort can be provided.

[0158] · Control of Video for Backstroke For a swimmer doing backstroke, a display different from Display 2 may be further arranged above Pool 1 to display content corresponding to the movement of the swimmer. For example, a starry sky or the like may be displayed on the display. Regarding this display as well, a target indicating the basic position may be displayed in the same manner as Display 2.

[0159] · Example of Vehicle FIG. 20 is a diagram showing a vehicle equipped with an entertainment pool.

[0160] In the vehicle 271 shown in FIG. 20, a pool 1 and various devices such as a display 2 provided around the pool 1 are mounted. The control device 21 is provided inside the vehicle 271. The control device 21 may be provided outside the vehicle 271 and connected to each device provided around the pool 1 via the Internet or the like. In this way, the pool 1 having the above configuration may be installed in the loading part of the vehicle.
