TECHNICAL FIELD

[0001] The present application relates to a movement promotion system, a control method, and a computer-readable medium. BACKGROUND

[0002] Patent Literature 1 (Japanese Patent Application Publication No. 2022-65360) discloses a foot pedal exercise device.

[0003] Further, in order to eliminate the daily exercise deficiency accompanying the sedentary work, it is typical to preferably provide a lower limb exercise device under a desk. That is, if the lower limb exercise device is used to perform the lower limb exercise while maintaining the sitting posture as it is in the sedentary work, the daily exercise deficiency can be eliminated without intentionally securing the time for exercise.

[0004] However, merely providing the lower limb exercise device under the desk does not necessarily mean that everyone will perform the lower limb exercise. SUMMARY

[0005] Therefore, an object of the present disclosure is to provide a technology that stimulates the motivation of the lower limb exercise performed in parallel with the work.

[0006] According to a first aspect of the present disclosure, a movement promotion system is provided, including: a work environment providing device that provides a work environment for making a user's work efficient; a movement state detecting section that detects a movement state of a lower limb of the user; and a work environment changing section that changes the work environment provided by the work environment providing device, the work environment changing section changing the work environment in a manner to deteriorate the work environment in a case where the movement state detected by the movement state detecting section does not satisfy a prescribed criterion. According to the above configuration, the motivation of the lower limb exercise performed in parallel with the work can be stimulated.

[0007] It can also be that the work environment changing section changes the work environment in a manner to improve the work environment in a case where the movement state detected by the movement state detecting section satisfies the prescribed criterion after changing the work environment in a manner to deteriorate the work environment. According to the above configuration, the motivation of the lower limb exercise performed in parallel with the work can be further stimulated.

[0008] The movement state not satisfying the prescribed criterion can also mean that the lower limb of the user is not exercised.

[0009] The movement state not satisfying the prescribed criterion can also mean that a state in which the lower limb of the user is not exercised continues for a prescribed time or more.

[0010] The movement state not satisfying the prescribed criterion can also mean that the exercise load of the lower limb of the user is lower than the prescribed criterion.

[0011] Also, the work environment providing device can be a desk, and the work environment changing section can change a state of a top plate of the desk in a manner that the state of the top plate of the desk deviates from an appropriate state, in a case where the motion state detected by the motion state detecting section does not satisfy the prescribed criterion.

[0012] Also, the work environment providing device can be a chair, and the work environment changing section can change a state of a seat surface of the chair in a manner that the state of the seat surface of the chair deviates from an appropriate state, in a case where the motion state detected by the motion state detecting section does not satisfy the prescribed criterion.

[0013] Also, the work environment providing device can be a display, and the work environment changing section can change a state of a display of the display in a manner that the state of the display of the display deviates from an appropriate state, in a case where the motion state detected by the motion state detecting section does not satisfy the prescribed criterion.

[0014] The state of the display of the display can indicate at least any one of a height, a pitch angle, a horizontal angle, an effective area, a brightness, and a contrast of an image display surface of the display.

[0015] According to a second aspect of the present disclosure, there is provided a control method, which is a control method of a motion promotion system that includes a work environment providing device that provides a work environment for making a user's work efficient, in which the motion promotion system detects a motion state of a lower limb of the user, and in which the motion promotion system changes the work environment in a manner that deteriorates the work environment, in a case where the motion state does not satisfy a prescribed criterion. According to the above method, motivation for lower limb motion performed in parallel with work can be stimulated.

[0016] There is provided a program that causes a computer to execute the above method.

[0017] Effects of Invention

[0018] According to the present disclosure, motivation for lower limb motion performed in parallel with work can be stimulated.

[0019] The above and other objects, features and advantages of the present disclosure will be more fully understood from the following detailed description taken in conjunction with the accompanying drawings, which are to be considered illustrative only, and not in a limiting sense.

[0030] Hereinafter, referring to Figures 1-10 An embodiment of the present disclosure will be described.

[0031] A case in which a user U seated on a chair 1 uses a desk computer 2 to perform a sedentary work is shown in Figure 1 A pedal exercise device 4 is provided below a table 3. In this configuration, the user U is enabled to perform a pedal exercise using the pedal exercise device 4 in the sedentary work. The pedal exercise device 4 is one specific example of a lower limb exercise device. As the lower limb exercise device, a pedal exercise device is also considered in addition to the pedal exercise device 4.

[0032] The table 3 includes a top plate 3a and a lifting device 3b. The lifting device 3b supports the top plate 3a, and raises and lowers the top plate 3a based on an external instruction. The lifting device 3b is typically configured by a linear actuator.

[0033] The chair 1 includes a seat surface la, a backrest lb, and a lifting device lc. The lifting device lc supports the seat surface la and the backrest lb, and raises and lowers the seat surface la and the backrest lb based on an external instruction. The lifting device lc is typically configured by a linear actuator.

[0034] A liquid crystal display 5 is provided on a top plate 3a of the table 3. The liquid crystal display 5 has an image display surface 5a and a support mechanism 5b. The support mechanism 5b supports the image display surface 5a, and adjusts the height, the pitch angle, and the horizontal angle of the image display surface 5a based on an external instruction. Here, the height of the image display surface 5a of the liquid crystal display 5 is typically a relative height with respect to the line of sight of the user U. The pitch angle of the image display surface 5a of the liquid crystal display 5 is an angle formed by a horizontal plane and an imaginary line orthogonal to the image display surface 5a of the liquid crystal display 5. The horizontal angle of the image display surface 5a of the liquid crystal display 5 is an orientation determined when the image display surface 5a of the liquid crystal display 5 is viewed from above. The support mechanism 5b is typically composed of a linear actuator and a rotary actuator.

[0035] A movement promoting device 7 is provided at the rear of the desk computer 2. The movement promoting device 7 is configured to motivate the user U, and to cause the user U to moderately perform a pedaling movement using the pedaling movement device 4 in a sedentary work.

[0036] The pedaling movement device 4 has a pair of pedals 4b supported by a pair of crank arms. The pair of pedals 4b are rotatably supported by the pair of crank arms. The pair of crank arms are connected to a crank shaft rotatably supported by the movement device main body 4a. Thus, the pair of pedals 4b are linked to each other. A load device that applies a load to the rotation of the crank shaft is mounted on the movement device main body 4a. The load device is typically an electromagnetic brake. The movement device main body 4a also has a crank shaft angle sensor 4c that detects the crank shaft angle of the crank shaft. The crank shaft angle sensor 4c transmits crank shaft angle data indicating the detected crank shaft angle to the movement promoting device 7.

[0037] The support mechanism 5b, the lifting device 1c, and the lifting device 3b are electrically connected to the movement promoting device 7. The movement promoting device 7 controls the operation of the support mechanism 5b, the lifting device 1c, and the lifting device 3b by outputting a control signal to the support mechanism 5b, the lifting device 1c, and the lifting device 3b.

[0038] The chair 1, the table 3, and the liquid crystal display 5 are provided to make the work of the user U efficient. That is, the chair 1, the table 3, and the liquid crystal display 5 assist the work of the user U. Therefore, the chair 1, the table 3, and the liquid crystal display 5 provide a work environment for making the work of the user U efficient. The work environment provided by the chair 1 is to achieve a sitting posture of the user U. The work environment provided by the table 3 is to support an input device such as a keyboard 8 used by the user U at an appropriate height. The work environment provided by the liquid crystal display 5 is to achieve a reasonable head posture and to display an image with less visual load.

[0039] InFigure 2 A functional block diagram of the exercise promoting device 7 is shown in FIG. 9. As shown in FIG. 9, the exercise promoting device 7 is provided with a CPU 7a (Central Processing Unit) as a central arithmetic processor, a RAM 7b (Random Access Memory) which is freely read and written, and a ROM 7c (Read Only Memory) which is read only. Further, the CPU 7a reads out a control program stored in the ROM 7c and executes it, whereby the control program causes the CPU 7a and the like to function as the exercise state detecting section 10 and the work environment changing section 11. Figure 2

[0040] The exercise promoting device 7 receives crank angle data from the crank angle sensor 4c of the pedal exercise device 4, for example, at every second. The exercise promoting device 7 receives image signals from the desk computer 2. Further, the exercise promoting device 7 outputs the received image signals to the liquid crystal display 5.

[0041] The exercise state detecting section 10 detects the exercise state of the user U on the basis of the crank angle data received from the crank angle sensor 4c of the pedal exercise device 4. The exercise state can include the presence or absence of the exercise using the pedal exercise device 4 by the user U, the load of the exercise using the pedal exercise device 4 by the user U, and all other states related to the exercise performed by the user U using the pedal exercise device 4.

[0042] The work environment changing section 11 changes the work environment provided by the chair 1, the desk 3, and the liquid crystal display 5. Specifically, the work environment changing section 11 changes the work environment in such a manner as to deteriorate the work environment in the case where the exercise state detected by the exercise state detecting section 10 does not satisfy a prescribed criterion. Then, the work environment changing section 11 changes the work environment in such a manner as to improve the work environment in the case where the exercise state detected by the exercise state detecting section 10 satisfies the prescribed criterion after the work environment is changed in such a manner as to deteriorate the work environment. According to the above-described configuration, in the case where the exercise state does not satisfy the prescribed criterion, the work environment for the sedentary work deteriorates and it becomes difficult to perform the sedentary work, so the user U continues or restarts the pedal exercise using the pedal exercise device 4, so that the work environment for the sedentary work does not deteriorate. In this way, the user U is motivated to perform the exercise in parallel with the sedentary work, so that the original purpose of eliminating the daily exercise deficiency can be achieved.

[0043] Next, the operation of the exercise promoting device 7 will be described with reference to Figures 3-10 Figure 3 The operation flow of the exercise promoting device 7 is shown in FIG. 10.

[0044] ​​S100:

[0045] First, the motion state detecting section 10 detects the motion state of the lower limbs of the user U on the basis of the crank angle data received from the crank angle sensor 4c of the pedal exercise device 4.

[0046] S110:

[0047] Next, the work environment changing section 11 determines whether or not the motion state of the lower limbs of the user U detected by the motion state detecting section 10 satisfies a prescribed criterion. In the case where the motion state of the lower limbs of the user U detected by the motion state detecting section 10 satisfies the prescribed criterion (S110: YES), the work environment changing section 11 returns the processing to S100. On the other hand, in the case where the motion state of the lower limbs of the user U detected by the motion state detecting section 10 does not satisfy the prescribed criterion (S110: NO), the work environment changing section 11 advances the processing to S120.

[0048] The work environment changing section 11, for example, determines that the motion state of the lower limbs of the user U detected by the motion state detecting section 10 satisfies the prescribed criterion in the case where it is possible to detect that the user U is exercising using the pedal exercise device 4, and determines that the motion state of the lower limbs of the user U detected by the motion state detecting section 10 does not satisfy the prescribed criterion in the case where it is not possible to detect that the user U is exercising using the pedal exercise device 4.

[0049] Further, the work environment changing section 11, for example, determines that the motion state of the lower limbs of the user U detected by the motion state detecting section 10 satisfies the prescribed criterion in the case where it is possible to detect that the user U is exercising using the pedal exercise device 4, and determines that the motion state of the lower limbs of the user U detected by the motion state detecting section 10 does not satisfy the prescribed criterion in the case where it is not possible to detect that the user U is exercising using the pedal exercise device 4 for a prescribed time or more.

[0050] Further, the work environment changing section 11, for example, determines that the motion state of the lower limbs of the user U detected by the motion state detecting section 10 satisfies the prescribed criterion in the case where the crank speed of the pedal exercise device 4 exceeds a prescribed speed, and determines that the motion state of the lower limbs of the user U detected by the motion state detecting section 10 does not satisfy the prescribed criterion in the case where the crank speed of the pedal exercise device 4 is lower than the prescribed speed.

[0051] In this way, the "prescribed criterion" is used to determine whether or not the user U is exercising using the pedal exercise device 4 without slacking. That is, it is assumed that the prescribed criterion is satisfied if the user U is exercising using the pedal exercise device 4 without slacking.

[0052] S120:

[0053] Next, the work environment changing section 11 changes the work environment in a manner to deteriorate the work environment.

[0054] Figure 4 A case in which the work environment changing section 11 deteriorates the work environment is shown. In this case, the work environment changing section 11 transmits a control instruction to the lifting device 3b of the table 3 to raise the top plate 3a by 10 cm. The lifting device 3b of the table 3 raises the top plate 3a of the table 3 by 10 cm based on the received control instruction. As a result, the top plate 3a of the table 3 is raised, and as a result, the work environment is deteriorated. That is, in this case, the height of the top plate 3a of the table 3 is higher than the appropriate height by 10 cm. Figure 4 Figure 4

[0055] In this case, the elbows of the user U protrude forward, and thus, the muscles around the shoulders such as the trapezius muscle are easily fatigued. At the same time, the height of the image display surface 5a of the liquid crystal display 5 is higher than the appropriate height, and thus, the line of sight is directed upward to induce dry eye, and the head is tilted backward, and thus, the trapezius muscle is easily fatigued. In addition, the head of the user U cannot be included in the angle of view of the image display surface 5a of the liquid crystal display 5, and thus, the actual contrast of the image display surface 5a is deteriorated.

[0056] Figure 5 A case in which the work environment changing section 11 deteriorates the work environment is shown. In this case, the work environment changing section 11 transmits a control instruction to the support mechanism 5b of the liquid crystal display 5 to raise the image display surface 5a of the liquid crystal display 5 by 10 cm and to direct the image display surface 5a upward by a prescribed amount of angle. The support mechanism 5b of the liquid crystal display 5 raises the image display surface 5a of the liquid crystal display 5 by 10 cm and directs the image display surface 5a upward by a prescribed amount of angle based on the received control instruction. As a result, the image display surface 5a of the liquid crystal display 5 is raised and directed upward, and as a result, the work environment is deteriorated. That is, in this case, the height of the image display surface 5a of the liquid crystal display 5 is higher than the appropriate height by 10 cm, and the pitch angle of the image display surface 5a is increased by a prescribed amount of angle toward the upward side. Figure 5 Figure 5

[0057] In this case, the height of the image display surface 5a of the liquid crystal display 5 is higher than the appropriate height, and thus, the line of sight is directed upward to induce dry eye, and the head is tilted backward, and thus, the trapezius muscle is easily fatigued. In addition, the head of the user U cannot be included in the angle of view of the image display surface 5a of the liquid crystal display 5, and thus, the actual contrast of the image display surface 5a is deteriorated.

[0058] Figure 6 A case in which the work environment changing section 11 deteriorates the work environment is shown. In this case, the work environment changing section 11 transmits a control instruction to the support mechanism 5b of the liquid crystal display 5 to raise the image display surface 5a of the liquid crystal display 5 by 10 cm and to direct the image display surface 5a upward by a prescribed amount of angle. The support mechanism 5b of the liquid crystal display 5 raises the image display surface 5a of the liquid crystal display 5 by 10 cm and directs the image display surface 5a upward by a prescribed amount of angle based on the received control instruction. As a result, the image display surface 5a of the liquid crystal display 5 is raised and directed upward, and as a result, the work environment is deteriorated. That is, in this case, the height of the image display surface 5a of the liquid crystal display 5 is higher than the appropriate height by 10 cm, and the pitch angle of the image display surface 5a is increased by a prescribed amount of angle toward the upward side. Figure 6 ​​​​In one example, the work environment change unit 11 sends a control command to the lifting device 1c of chair 1, causing the seat 1a of chair 1 to lower by 10 centimeters. Based on the received control command, the lifting device 1c of chair 1 lowers the seat 1a of chair 1 by 10 centimeters. As a result, the seat 1a of chair 1 lowers, and consequently, the work environment deteriorates. That is, in Figure 6 In this case, the height of the seat 1a of chair 1 is 10 cm lower than the appropriate height.

[0059] In this situation, the user U's elbows protrude forward, causing muscles around the shoulders, such as the deltoids, to easily fatigue. Simultaneously, the image display surface 5a of the liquid crystal display 5 is positioned higher than appropriate, causing the user to look upwards and inducing dry eye, and causing the head to tilt backwards, thus easily fatigued the trapezius muscles. Furthermore, the user U's head cannot be positioned within the field of view of the image display surface 5a of the liquid crystal display 5, resulting in a deterioration in the actual contrast of the image display surface 5a.

[0060] exist Figure 7 A suitable display example of the image display surface 5a of the liquid crystal display 5 is shown. Figure 7 In the illustrated example, the entire image display surface 5a of the liquid crystal display 5 is the effective area, and the image is displayed across the entire image display surface 5a. Furthermore, the brightness and contrast of the image display surface 5a of the liquid crystal display 5 are also at appropriate values.

[0061] In response, Figures 8-10 The following example is shown: The working environment modification unit 11 deteriorates the working environment associated with the LCD 5 by processing the image signal received from the desktop computer 2 and outputting it to the LCD 5.

[0062] exist Figure 8 In this configuration, only the narrow central area 12 of the image display surface 5a of the liquid crystal display 5 is considered the effective area, while the other areas 13 are designated as ineffective areas. That is, in... Figure 8 In this case, the image that should have been displayed on the entire image display surface 5a is reduced in size and displayed in area 12. As a result, the text displayed in area 12 on the image display surface 5a becomes smaller, which can easily cause eye strain.

[0063] exist Figure 9 In this case, the brightness of the image display surface 5a of the liquid crystal display 5 is higher than the appropriate brightness. This can cause eye strain due to glare.

[0064] exist Figure 10 In this case, the contrast of the image display surface 5a of the liquid crystal display 5 is lower than an appropriate contrast. As a result, the text displayed on the image display surface 5a becomes difficult to read, leading to eye strain.

[0065] S130:

[0066] return Figure 3 Next, the motion state detection unit 10 detects the motion state of the user U's lower limbs based on the crankshaft angle data received from the motion device body 4.

[0067] S140:

[0068] Next, the work environment modification unit 11 determines whether the movement state of the user U's lower limbs detected by the motion state detection unit 10 meets the prescribed benchmark. If the movement state of the user U's lower limbs detected by the motion state detection unit 10 meets the prescribed benchmark (S140: Yes), the work environment modification unit 11 moves the process to S150. On the other hand, if the movement state of the user U detected by the motion state detection unit 10 does not meet the prescribed benchmark (S140: No), the work environment modification unit 11 returns the process to S130.

[0069] S150:

[0070] Next, the work environment change unit 11 changes the work environment in a way that improves the work environment.

[0071] That is, in Figure 4 In one example, the work environment change department 11 sends a control command to the lifting device 3b of table 3, such as lowering the top plate 3a by 10 centimeters.

[0072] In addition, Figure 5 In the example, the working environment change unit 11 sends a control command to the support mechanism 5b of the liquid crystal display 5, which lowers the image display surface 5a of the liquid crystal display 5 by 10 centimeters and makes the image display surface 5a face downward at a specified angle.

[0073] In addition, Figure 6 In one example, the work environment change unit 11 sends a control command to the lifting device 1c of chair 1, such that the seat 1a of chair 1 rises by 10 centimeters.

[0074] In addition, Figures 8-10 In one example, the image signal received from the desktop computer 2 is output to the liquid crystal display 5 without any processing.

[0075] Thus, by restoring a suitable working environment for continuing the work, user U can focus on the work and eliminate daily lack of exercise.

[0076] Chair 1, table 3, and LCD monitor 5 are specific examples of equipment provided for the work environment. For example... Figure 2 As shown, the work environment providing equipment, the motion status detection unit 10, and the work environment modification unit 11 constitute the motion promotion system 50. Figure 1The lower limb motor system 51 shown includes a motor promotion system 50 and a foot pedal exercise device 4.

[0077] The embodiments of this disclosure have been described above, and the above embodiments have the following features.

[0078] That is, the motion promotion system 50 includes: a work environment providing device (e.g., table 3) that provides a work environment that optimizes the user U's work efficiency; a motion state detection unit 10 that detects the motion state of the user U's lower limbs; and a work environment modification unit 11 that modifies the work environment provided by the work environment providing device. If the motion state detected by the motion state detection unit 10 does not meet a predetermined standard, the work environment modification unit 11 modifies the work environment in a way that deteriorates the work environment. Based on the above configuration, it is possible to stimulate the motivation for lower limb movements that occur concurrently with work.

[0079] Furthermore, after the work environment modification unit 11 changes the work environment in a way that would worsen it, if the motion state detected by the motion state detection unit 10 meets a prescribed benchmark, the work environment modification unit 11 changes the work environment in a way that would improve it. Based on this configuration, the motivation for lower limb movements performed concurrently with work can be further stimulated.

[0080] In addition, the failure of the exercise state to meet the specified benchmarks means any one of the following: user U's lower limbs are not moving, the user's lower limbs are not moving for more than a specified time, or the user's lower limb exercise load is lower than the specified benchmarks.

[0081] Alternatively, if the motion state detected by the motion state detection unit does not meet the prescribed benchmark, the work environment change unit 11 may change the state of the table top plate in a way that moves the state of the table top plate away from the appropriate state.

[0082] Furthermore, when the work environment providing device is a chair 1, if the motion state detected by the motion state detection unit 10 does not meet the prescribed benchmark, the work environment modification unit 11 changes the state of the seat surface 1a of the chair 1 in a manner that deviates from the appropriate state. In this case, typically, the work environment modification unit 11 makes the height of the seat surface 1a of the chair 1 higher or lower than the appropriate height. The work environment modification unit 11 may also make the pitch posture of the seat surface 1a of the chair 1 tilt forward or backward than the appropriate posture. The work environment modification unit 11 may also make the lateral tilt posture of the seat surface 1a of the chair 1 tilt to the right or left than the appropriate posture.

[0083] Furthermore, when the operating environment providing device is a liquid crystal display (LCD) 5, if the motion state detected by the motion state detection unit 10 does not meet the prescribed benchmark, the operating environment modification unit 11 changes the display state of the LCD 5 in a manner that causes the display state of the LCD 5 to deviate from the appropriate state. The display state of the LCD 5 is at least one of the following: height, tilt angle, horizontal angle, effective area, brightness, and contrast of the image display surface 5a of the LCD 5. The support mechanism 5b of the LCD 5 can increase or decrease the height, tilt angle, and horizontal angle of the image display surface 5a of the LCD 5.

[0084] Furthermore, the control method of the motion promotion system 50, which provides a work environment providing equipment for improving the work efficiency of user U, includes the following steps: the motion promotion device 7 of the motion promotion system 50 detects the motion state of user U's lower limbs (S100); and if the motion state does not meet the prescribed benchmark, the work environment is changed in a manner that deteriorates the work environment (S120). According to the above method, the motivation for lower limb movement that is performed in parallel with the work can be stimulated.

[0085] Programs can be stored and provided to a computer using any type of non-transitory computer-readable medium. Non-transitory computer-readable media include any type of tangible storage medium. Examples of non-transitory computer-readable media include: magnetic storage media (e.g., floppy disks, magnetic tapes, hard disk drives, etc.), optical-magnetic storage media (e.g., magneto-optical disks), CD-ROM (compact disc read-only memory), CD-R (compact disc recordable), CD-R / W (compact disc rewritable), and semiconductor memories (e.g., mask ROM, PROM (programmable ROM), EPROM (erasable PROM), Flash ROM, RAM (random access memory), etc.). Programs can also be provided to a computer using any type of transient computer-readable medium. Examples of transient computer-readable media include electrical signals, optical signals, and electromagnetic waves. Transient computer-readable media can provide programs to a computer via wired communication lines (e.g., electrical wires and optical fibers) or wireless communication lines.

[0086] As will be apparent from the present disclosure as described herein, embodiments of the present disclosure may be varied in many ways. Such variations should not be considered as departing from the concept and scope of the present disclosure, and it will be apparent to those skilled in the art that all such modifications are intended to be included within the scope of the claims.
