[0012] As shown in Fig. 1, the mat device 10 includes a mat 12, a light emitting unit 14, a plurality of sensor units 16, and a control device 18. The mat device 10 displays guide positions that indicate positions where the user should place body parts to perform various yoga poses on the mat 12. In this embodiment, an example of displaying guide values ​​for performing yoga poses will be described, but the present invention is not limited to this. The present invention can also be applied to poses for other exercises.

[0013] The mat 12 is a mat on which the user performs exercises including yoga. The mat 12 may be, for example, a known mat.

[0014] The light-emitting unit 14 is provided to display various information on the mat 12. The light-emitting unit 14 is a type of display unit. The light-emitting unit 14 may be, for example, a light-emitting panel that emits various lights. For example, when the light-emitting unit 14 is a light-emitting panel including a display or a light, the translucent, flexible mat 12 may be placed on the light-emitting unit 14. In this case, a positioning marker may be provided on the mat 12 to align the mat 12 with the light-emitting unit 14. The light-emitting unit 14 may be placed on the mat 12. That is, the vertical positional relationship between the mat 12 and the light-emitting unit 14 may be arbitrary. The light-emitting unit 14 displays, for example, a guide position indicating a position where one or more parts of the body are placed to perform various yoga poses according to the control of the control device 18. The light-emitting unit 14 is not limited to a light-emitting panel, and may be composed of other light-emitting bodies and light-emitting devices.

[0015] The sensor unit 16 is provided on the mat 12. The sensor unit 16 is provided, for example, at a plurality of positions on the mat 12. The sensor unit 16 detects an object located above the mat 12. The sensor unit 16 detects the distance between the upper surface of the mat 12 and an object located above the mat 12. The sensor unit 16 may be, for example, an infrared sensor including a light-emitting unit that emits infrared light to an object and a light-receiving unit that receives infrared light reflected from the object. The sensor unit 16 is not limited to an infrared sensor and may be another distance sensor.

[0016] The control device 18 controls the light-emitting unit 14 and the sensor unit 16. The control device 18 is communicatively connected to the light-emitting unit 14 and the sensor unit 16, for example, via a wired or wireless network (not shown). The control device 18 is provided, for example, outside the mat 12. The control device 18 may be provided, for example, inside the mat 12.

[0017] As shown in FIG. 2, the control device 18 includes an input unit 20, a storage unit 22, a communication unit 24, and a control unit .

[0018] The input unit 20 accepts various input operations to the control device 18. The input operations include, for example, an operation for displaying a guide position on the light-emitting unit 14 and an operation for ending the display of the guide position. The input unit 20 is configured using a well-known input device.

[0019] The storage unit 22 is a memory that stores various information such as the contents of calculations and programs of the control unit 26. The storage unit 22 stores, for example, posture information related to the positions of body parts on the mat 12 to assume yoga poses. The storage unit 22 includes, for example, at least one of a main storage device such as a RAM (Random Access Memory) and a ROM (Read Only Memory), and an external storage device such as an HDD (Hard Disk Drive).

[0023] The light emission control unit 30 controls the light emission unit 14. The light emission control unit 30 controls, for example, the light emission unit 14 to emit light. The light emission control unit 30 controls, for example, the light emission unit 14 to emit light and display guide positions indicating positions at which one or more parts of the body are to be positioned to perform various yoga poses. That is, the light emission control unit 30 is a type of display control unit. The light emission control unit 30 acquires, for example, posture information related to yoga poses from the storage unit 22, and controls the light emission unit 14 according to the acquired posture information to display the guide positions. The light emission control unit 30 may acquire posture information from another external device, for example, via the communication unit 24. The posture information includes information related to positions at which parts of the body are to be positioned to perform poses.

[0024] The light-emitting control unit 30 may, for example, control the light-emitting unit 14 to display the guide position in different forms depending on the part of the body. The light-emitting control unit 30 may, for example, control the light-emitting unit 14 to display the guide position in different forms depending on the height of the part of the body from the mat 12.

[0025] The sensor control unit 32 controls the sensor unit 16. For example, the sensor control unit 32 controls the sensor unit 16 to detect an object on the upper surface of the mat 12. For example, the sensor control unit 32 controls the sensor unit 16 to detect a distance between the upper surface of the mat 12 and an object located away from the upper surface of the mat 12.

[0026] The determination unit 34 determines various pieces of information. For example, the determination unit 34 determines various pieces of information based on the detection result of the sensor unit 16. For example, the determination unit 34 determines whether the user has performed a yoga pose corresponding to the guide position displayed by the light-emitting unit 14 based on the detection result of the sensor unit 16.

[0027] The communication control unit 36 ​​controls the communication unit 24 to perform communication between the light emitting unit 14 and the control device 18. The communication control unit 36 ​​controls the communication unit 24 to perform communication between the sensor unit 16 and the control device 18.

Guide positions G42B and G43B indicating the guide positions of the right hand and left to be placed on the mat 12 are displayed as guide positions with a coloring.

[0054] In the first to third modes, the size of each guide position may be changed according to the size of the body part to be placed. Also, the position at which each guide position is displayed may be changed according to the height of the user. In this case, height information on the height of the user may be stored in the storage unit 22, and the position at which each guide position is displayed may be changed based on the height information.

[0055] Returning to FIG. 3, the determination unit 34 determines whether or not to determine that the user has taken a pose (step S14). Specifically, the determination unit 34 determines to determine that the user has taken a pose when, for example, an input is made to the input unit 20 to perform a process of determining that the user has taken a pose. If it is determined that the user has taken a pose (step S14; Yes), the process proceeds to step S16. If it is not determined that the user has taken a pose (step S14; No), the process proceeds to step S20. Note that, if it is not determined that the user has taken a pose, the mat device 10 does not need to include the sensor unit 16, the sensor control unit 32, and the determination unit 34.

[0056] If the result of the determination in step S14 is Yes, the determination unit 34 determines whether or not a pose has been taken (step S16). Specifically, the determination unit 34 determines whether or not a pose has been taken based on the detection result of the positions of each part of the user's body by the sensor unit 16. If it is determined that a pose has been taken (step S16; Yes), the process proceeds to step S18. If it is not determined that a pose has been taken (step S16; No), the process of step S16 is repeated.

[0057] If the answer to step S16 is Yes, the light emission control unit 30 determines whether or not a predetermined time has elapsed since the determination unit 34 determined that the user paused (step S18). The predetermined time after the pause may be predetermined according to the pause, or may be arbitrarily set by the user. If it is determined that the predetermined time has elapsed after the pause (step S18; Yes), the process proceeds to step S22. If it is not determined that the predetermined time has elapsed after the pause (step S18; No), the process of step S18 is repeated.

[0058] If it is determined No in step S14, the light emission control unit 30 determines whether or not a predetermined time has elapsed after the guide position is displayed (step S20). The predetermined time after the guide position is displayed may be determined in advance according to the displayed guide position, or may be arbitrarily set by the user. If it is determined that the predetermined time has elapsed after the guide position is displayed (step S20; Yes), the process proceeds to step S22. If it is not determined that the predetermined time has elapsed after the guide position is displayed (step S20; No), the process of step S20 is repeated.

[0059] If it is determined that the answer is Yes in step S18 or Yes in step S20, the light emission control unit 30 makes the guide position non-displayable (step S22), and then ends the processing in FIG.

[0060] As described above, in the first embodiment, guide positions indicating positions for positioning body parts for posing in yoga or the like are displayed on the mat 12. This allows the user to understand positions for positioning body parts on the mat 12. As a result, in the first embodiment, the user can appropriately pose by following the guide positions displayed on the mat 12.

[0061] [First Modification of the First Embodiment] The processing contents of the control device according to the first modified example of the first embodiment will be described with reference to Fig. 9. Fig. 9 is a flowchart showing an example of the flow of processing of the control device according to the first modified example of the first embodiment. As shown in Fig. 9, in the first modified example of the first embodiment, guide positions may be displayed in different colors depending on the part of the body.

[0062] The processes in step S30 and steps S34 to S42 are the same as those in step S10 and steps S14 to S22 shown in FIG. 3, and therefore will not be described.

[0063] After step S30, the light-emission control unit 30 displays the guide position in a different color depending on the part (step S32). Specifically, the light-emission control unit 30 controls, for example, the light-emission unit 14 to display the guide position in a different color depending on the part based on the posture information acquired in step S30.

[0064] A method of displaying the guide position in different colors depending on the part will be described with reference to Fig. 10. Fig. 10 is a diagram for explaining a method of displaying the guide position in different colors depending on the part. Fig. 10 shows, as an example, a method of displaying the guide position of the first pose in different colors depending on the part.

[0065] As shown in FIG. 10, the light-emitting control unit 30 controls the light-emitting unit 14, for example, to display guide positions G1C, G2C, G3C, and G4C. Guide position G1C indicates a position for placing the palm of the left hand. Guide position G2C indicates a position for placing the palm of the right hand. Guide position G3C indicates a position for placing the sole of the left foot. Guide position G4C indicates a position for placing the sole of the right foot. For example, the light-emitting control unit 30 displays guide positions G1C and G2C in the same color. For example, the light-emitting control unit 30 displays guide positions G3C and G4C in the same color. For example, the light-emitting control unit 30 displays guide positions G1C and G2C, and guide positions G3C and G4C in different colors. For example, the light emission control unit 30 displays guide positions G1C and G2C in a relatively light color, and displays guide positions G3C and G4C in a relatively dark color. For example, the light emission control unit 30 displays guide positions G1C and G2C in red, and displays guide positions G3C and G4C in blue. That is, the difference in color between guide positions G1C and G2C and guide positions G3C and G4C may be arbitrary.

[0066] As described above, in the first modified example of the first embodiment, guide positions of different colors are displayed on the mattress according to the body parts. This makes it easier for the user to understand the body parts to be positioned when posing in the first modified example of the first embodiment.

[0067] [Second Modification of the First Embodiment] The processing contents of the control device according to the second modified example of the first embodiment will be described with reference to Fig. 11. Fig. 11 is a flowchart showing an example of the flow of processing of the control device according to the second modified example of the first embodiment. As shown in Fig. 13, in the second modified example of the first embodiment, guide positions may be displayed in different colors depending on the height at which the body part is placed.

[0068] The processes in step S50, steps S54 to S56, and steps S60 to S64 are the same as the processes in step S10 and steps S14 to S22 shown in FIG. 3, and therefore will not be described.

[0069] After step S50, the light-emission control unit 30 displays a guide position of a different color according to the height at which the body part is placed and a level bar indicating the height (step S52). Specifically, the light-emission control unit 30 controls, for example, the light-emission unit 14 to display a guide position of a different color according to the height at which the body part is placed based on the posture information acquired in step S50.

[0070] A method of displaying the guide position in a different color depending on the height at which the body part is arranged will be described with reference to Fig. 12A and Fig. 12B. Fig. 12A and Fig. 12B are diagrams for explaining a method of displaying the guide position in a different color depending on the height at which the body part is arranged. Fig. 12A and Fig. 12B show, as an example, a method of displaying the guide position of the third pose in a different color depending on the height at which the body part is arranged.

[0071] 12A, the light-emission control unit 30 controls the light-emitting unit 14, for example, to display guide positions G41C, G42C, G43C, G44C, and a level bar LB. Guide position G41C indicates the position where the left hand is placed horizontally above the mat 12. Guide position G42C indicates the position where the palm of the right hand is placed. Guide position G43C indicates the position where the knee of the left foot is placed. Guide position G44C indicates the position where the right foot is placed horizontally above the mat 12. The level bar LB indicates the correspondence between the color of each guide position and the height above the mat 12.

[0072] The light emission control unit 30, for example, displays the guide position G41C and the guide position G44C in the same color. The light emission control unit 30, for example, displays the guide position G42C and the guide position G43C in the same color. The light emission control unit 30, for example, displays the guide position G41C and the guide position G44C, and the guide position G42C and the guide position G43C in different colors. The light emission control unit 30, for example, displays the guide position G41C and the guide position G44C in a relatively light color, and displays the guide position G42C and the guide position G43C in a relatively dark color. The light emission control unit 30, for example, displays the guide position G41C and the guide position G44C in red, and displays the guide position G42C and the guide position G43C in blue. That is, the difference in color between the guide position G41C and the guide position G44C, and the guide position G42C and the guide position G43C may be arbitrary. Specifically, as long as there is a correspondence relationship with the height from the mat 12 indicated by the level bar LB, the difference in color between the guide positions G41C and G44C and the guide positions G42C and G43C may be arbitrary.

[0073] 12B, the light emission control unit 30 may not display, for example, the level bar LB. That is, the light emission control unit 30 may display, for example, only guide position G41C, guide position G42C, guide position G43C, and guide position G44C, each of which changes color according to height.

[0074] In step S52, the light-emission control unit 30 may display the absolute value of the target height from the mat 12 as the height, or may display the relative value of the height of the part with respect to the target height as the height. For example, when displaying the relative value of the height of the part with respect to the target height as the height, the light-emission control unit 30 may display the distance between the height of the part detected by the sensor unit 16 and the target height as a relative value.

[0075] If it is determined as Yes in step S56, the light emission control unit 30 makes the level bar LB invisible (step S58). That is, after it is determined that the user has correctly performed the yoga pose, the light emission control unit 30 proceeds to step S60.

[0076] As described above, in the second modified example of the first embodiment, guide positions of different colors are displayed on the mattress according to the spatial height at which the body is positioned on the mattress. This makes it easier for the user to grasp the spatial height at which the body is positioned when posing in the second modified example of the first embodiment. Also, in the second modified example of the first embodiment, the level bar LB makes it easier to grasp whether the pose is correct or not.

[0077] [Third Modification of the First Embodiment] The processing contents of the control device according to the third modified example of the first embodiment will be described with reference to Fig. 13. Fig. 13 is a flowchart showing an example of the flow of processing of the control device according to the third modified example of the first embodiment. As shown in Fig. 13, in the third modified example of the first embodiment, a guide position including directional information related to the direction in which the body is moved may be displayed.

[0078] The processes in step S70 and steps S74 to S78 are the same as those in step S10 and steps S14 to S18 shown in FIG. 3, and therefore will not be described.

[0079] After step S70, the light-emission control unit 30 displays a guide position including directional information (step S72). Specifically, the light-emission control unit 30 controls, for example, the light-emission unit 14 to display a guide position indicating a direction in which to move a body part based on the posture information acquired in step S70.

[0080] A method for displaying a guide position including directional information will be described with reference to Fig. 14. Fig. 14 is a diagram for explaining a method for displaying a guide position including directional information. Fig. 14 shows, as an example, a method for displaying a guide position including directional information of the third pose.

[0081] As shown in FIG. 14, in the first mode, the light-emission control unit 30 controls the light-emission unit 14, for example, to display guide positions G41D, G42D, G43D, and G44D. The guide position G41D indicates the position where the left hand is placed horizontally above the mat 12. The guide position G42D indicates the position where the palm of the right hand is placed. The guide position G43D indicates the position where the knee of the left foot is placed. The guide position G44D indicates the position where the right foot is placed horizontally above the mat 12. As shown in FIG. 14, the light-emission control unit 30 displays the guide positions G41D and G44D with arrows. The direction indicated by the arrow is the direction in which the body is moved. That is, the guide position G41D indicates the direction in which the left hand is moved, and the guide position G44D indicates the direction in which the right foot is moved.

[0082] As shown in FIG. 14, in the second mode, the light emission control unit 30 controls the light emission unit 14 to display guide positions G41E, G42E, G43E, and G44E, for example. Guide position G41E indicates the position where the left hand is placed horizontally above the mat 12. Guide position G42E indicates the position where the palm of the right hand is placed. Guide position G43E indicates the position where the knee of the left foot is placed. Guide position G44E indicates the position where the right foot is placed horizontally above the mat 12. The light emission control unit 30 displays the guide positions G41E and G44E with arrows. That is, guide position G41E indicates the direction in which the left hand moves, and guide position G44E indicates the direction in which the right foot moves.

[0083] As shown in FIG. 14, in the third mode, the light emission control unit 30 controls the light emission unit 14 to display guide positions G41F, G42F, G43F, and G44F, for example. Guide position G41F indicates the position where the left hand is placed horizontally above the mat 12. Guide position G42F indicates the position where the palm of the right hand is placed. Guide position G43F indicates the position where the knee of the left foot is placed. Guide position G44F indicates the position where the right foot is placed horizontally above the mat 12. The light emission control unit 30 displays guide positions G41F and G44F with arrows. That is, guide position G41F indicates the direction in which the left hand moves, and guide position G44F indicates the direction in which the right foot moves.

[0084] That is, when a pose is taken, the light emission control unit 30 displays the guide positions corresponding to the body parts to be moved including directional information, and displays the guide positions corresponding to the other body parts in the normal manner.

[0085] Returning to Fig. 13, if it is determined that the answer is Yes in step S78 or Yes in step S80, the light emission control unit 30 makes the guide position including the direction information non-display (step S82), and ends the processing in Fig. 13.

[0086] As described above, in the third modified example of the first embodiment, when it is necessary to move a body part when taking a pose, a guide position including information on the movement is displayed on the mattress. This makes it easier for the user to understand the body movements to be made when posing in the third modified example of the first embodiment.

[0087] [Fourth Modification of the First Embodiment] The processing contents of the control device according to the fourth modified example of the first embodiment will be described with reference to Fig. 15. Fig. 15 is a flowchart showing an example of the flow of processing of the control device according to the fourth modified example of the first embodiment. As shown in Fig. 15, in the first embodiment, characters may be displayed together with the guide position.

[0088] The processes in step S90 and steps S94 to S98 are the same as those in step S10 and steps S14 to S18 shown in FIG. 3, and therefore will not be described.

[0089] After step S90, the light emission control unit 30 displays the guide position and text (step S92). Specifically, the light emission control unit 30 controls, for example, the light emission unit 14 to display the guide position based on the attitude information acquired in step S90, and also displays text at the guide position.

[0090] A method for displaying the guide position and characters will be described with reference to Fig. 16. Fig. 16 is a diagram for explaining a method for displaying the guide position and characters. Fig. 16 shows a method for displaying the guide position and characters for the fifth pose.

[0091] As shown in FIG. 16, in the first mode, the light emission control unit 30 controls the light emission unit 14 to display, for example, guide positions G51, G52, G53, G54, and the letter L. The guide position G51 indicates a position for raising the left hand. The guide position G52 indicates a position for raising the right hand. The guide position G53 indicates a position for placing the sole of the left foot. The guide position G54 indicates a position for placing the sole of the left foot. For example, the light emission control unit 30 displays the letter L adjacent to the guide positions G51 and G52. The letter L is, for example, the letter "UP". The letter L indicates the movement of the hand at the positions of the guide positions G51 and G52. That is, the light emission control unit 30 displays the letter including the information indicating the movement of the body part adjacent to the guide position.

[0092] 16, in the second mode, the light-emission control unit 30 controls the light-emission unit 14, for example, to display guide positions G51A, G52A, G53A, G54A, and the letter L.

Guide position G53A indicates the position for placing the sole of the left foot. Guide position G54A indicates the position for placing the sole of the left foot. For example, the light-emission control unit 30 displays the letter L adjacent to guide position G51A and guide position G52A.

[0093] As shown in Fig. 16, in the third mode, the light-emission control unit 30 controls the light-emitting unit 14, for example, to display guide positions G51B, G52B, G53B, G54B, and the letter L. Guide position G51B indicates the position for raising the left hand. Guide position G52B indicates the position for raising the right hand. Guide position G53B indicates the position for placing the sole of the left foot. Guide position G54B indicates the position for placing the sole of the left foot. For example, the light-emission control unit 30 displays the letter L adjacent to guide positions G51B and G52B.

[0094] Returning to Fig. 15, if it is determined as Yes in step S98, the light emission control unit 30 makes the guide position and the characters non-displayable (step S102), and ends the processing in Fig. 15.

[0095] As described above, in the fourth modified example of the first embodiment, when it is necessary to move a body part, text information indicating the body movement is displayed adjacent to the guide position corresponding to that body part. This makes it easier for the user to grasp the body movement to be placed when posing in the fourth modified example of the first embodiment.

[0124] The projection device 40 projects light L onto the mat 12. For example, the projection device 40 displays each guide position on the surface of the mat 12 by projecting the light L onto the mat 12 according to the control of the control device 18A. Note that, in FIG. 23, the projection device 40 is described as projecting the light L from the upper surface of the mat 12, but the present invention is not limited to this. For example, the projection device 40 may be arranged to project the light L from the side of the mat 12. For example, the projection device 40 may be arranged at a position where the light L is not blocked by a user posing on the mat 12. In this embodiment, the surface of the mat 12 is a kind of display unit. The projection device 40 is, for example, configured with a well-known projector. In the second embodiment, the mat 12 may be a well-known one, or the upper surface of the mat 12 may be covered with a material that can project light like a projector screen. In this embodiment, a positioning marker may be provided on the mat 12 to align the position where the projection device 40 projects the light.

[0125] As shown in FIG. 24, a control unit 26A of a control device 18A differs from the control device 18 shown in FIG.

[0126] The projection control unit 38 controls the projection device 40. The projection control unit 38 controls, for example, the projection device 40 to project light. The projection control unit 38 controls, for example, the projection device 40 to project light, and displays guide positions on the surface of the mat 12, which indicate positions at which one or more parts of the body should be positioned to perform various yoga poses. That is, the projection control unit 38 is a type of display control unit. The projection control unit 38 acquires, for example, posture information related to yoga poses from the storage unit 22, and controls the projection device 40 according to the acquired posture information to display the guide positions on the upper surface of the mat 12.

[0127] The projection control unit 38 may, for example, control the projection device 40 to project light and display the guide values ​​on the mat 12 in different forms depending on the part of the body. The projection control unit 38 may, for example, control the projection device 40 to project light and display the guide values ​​on the mat 12 in different forms depending on the height of the part of the body from the mat 12.

[0128] As described above, in the second embodiment, the projection control unit 38 controls the projection device 40 to perform the same processing as in the first embodiment. That is, in the present invention, the light emitting unit 14 provided on the mat 12 or the projection device 40 that projects light onto the mat 12 is controlled to display a guide position that guides posing.
