[0001] The disclosed invention relates to a sleep management system and a sleep management method.

[0002] Sleep is essential to human health and well-being, playing a variety of roles, including helping the body recover, forming new memories, maintaining concentration, and clearing accumulated brain waste.

[0103] FIG. 3 illustrates configurations of a sleep management system according to one embodiment.

[0104] Referring to FIG. 3, in one embodiment, a user may wear a first wearable device (4) and / or a second wearable device (5) on a part of the user's body.

[0105] For example, the first wearable device (4) and the second wearable device (5) can be worn on both arms, but of course, they can be worn on various parts of the user's body, such as the user's ankles, waist, and neck.

[0106] The smart bed (6) may have a form in which a user can sit or lie down. For example, it may include a bed, a chair, and / or a sofa. However, it is understood that any piece of furniture in which a user can sit or lie down may be adopted as the smart bed (6) according to one embodiment without limitation.

[0107] A plurality of pressure sensors (601) may be installed at locations capable of measuring pressure generated by the user's body (e.g., whole body) depending on whether the user is lying down or sitting.

[0108] For example, if the smart bed (6) corresponds to a bed, a plurality of pressure sensors (601) may be provided on the mattress, which is a portion where pressure is generated by the user's body. The mattress may have a flat polygonal or circular shape, and may include a cover that forms an exterior and has a receiving space, and a pad that is provided in the receiving space of the cover and on which a plurality of pressure sensors (601) are arranged. The mattress may be placed on the floor, a chair, a sofa, or a bed.

[0109] The mattress may further include springs and / or sponges. The springs and / or sponges may be provided in the accommodation space of the cover.

[0110] The structure (e.g., length, arrangement, etc.) of the plurality of pressure sensors (601) may be changed depending on the size of the mattress.

[0111] The positions of the plurality of pressure sensors (601) are not limited to the example shown in FIG. 3, and the plurality of pressure sensors (601) may be installed in various positions capable of measuring the pressure generated by the body of a user lying or sitting on the smart bed (6).

[0112] Figure 4 illustrates a user's posture according to one embodiment.

[0113] Referring to FIG. 4, if a user lies on the smart bed (6) in a side-lying position, one arm may be pressed by the user's upper body. In this case, the blood flow to the pressed arm may be higher than that to the opposite arm. Accordingly, the heart rate measured in the pressed arm may be higher than that measured in the opposite arm.

[0114] For example, the first heart rate data collected by the first wearable device (4) from the arm pressed by the user's upper body may have a greater value than the second heart rate data collected by the second wearable device (5) from the opposite arm.

[0115] For another example, the greater the load applied to the arm by the user's upper body, the greater the difference between the first heart rate data and the second heart rate data may be.

[0116] For another example, referring to FIGS. 3 and 4, the difference between the first heart rate data and the second heart rate data may have a larger value when the user lies on the side than when the user lies upright looking at the ceiling on the smart bed (6).

[0117] FIG. 5 illustrates an example of a flowchart of a sleep management method according to one embodiment. FIG. 6 illustrates a flowchart of transmitting a posture change induction signal based on a difference value between first heart rate data and second heart rate data according to one embodiment.

[0118] The first wearable device (4) can collect first heart rate data (S1 of FIG. 5 and 1000 of FIG. 6). The second wearable device (5) can collect second heart rate data (S2 of FIG. 5 and 1100 of FIG. 6). The first heart rate data may include a heart rate collected at a first location on the user's body, and the second heart rate data may include a heart rate collected at a location different from the first location. The first location and the second location are not fixed locations on the user's body and may change depending on how the user wears the device.

[0119] The first wearable device (4) and / or the second wearable device (5) can transmit the first heart rate data and / or the second heart rate data to the server (2) (S3).

[0120] The server (2) can generate difference value information from the difference value between the first heart rate data and the second heart rate data (S4). The difference value information can include an electrical signal corresponding to the difference value and can include an electrical signal having a size proportional to the difference value.

[0121] The server (2) can decide whether to transmit the difference value information to the user device (3) (S5).

[0122] In one embodiment, the server (2) can determine whether to transmit difference value information generated from the difference value to the user device (3) based on the difference value between the first heart rate data and the second heart rate data.

[0123] For example, the server (2) may decide to transmit difference value information to the user device (3) based on the difference value between the first heart rate data and the second heart rate data being greater than or equal to the first reference value (example 1200 in FIG. 6).

[0124] The server (2) can transmit difference value information to the user device (3) (S6).

[0125] For example, the server (2) may transmit difference value information to the user device (3) based on a determination that the difference value information has been transmitted to the user device (3).

[0126] The user device (3) can generate a posture change induction signal based on the difference value information (S7). The user device (3) can transmit the generated posture change induction signal to the first wearable device (4), the second wearable device (5), and / or an external device (e.g., a smart bed (6)) (S8).

[0127] In one embodiment, the user device (3) may generate a posture change induction signal based on the difference between the first heart rate data and the second heart rate data being less than a second reference value (1300 No in FIG. 6), and transmit the generated posture change induction signal to the first wearable device (4) and / or the second wearable device (5). The second reference value means a value greater than the first reference value.

[0128] In one embodiment, the user device (3) may generate a posture change induction signal based on the difference between the first heart rate data and the second heart rate data being greater than or equal to the second reference value (example 1300 of FIG. 6), and transmit the generated posture change induction signal to the first wearable device (4), the second wearable device (5), and / or an external device (e.g., a smart bed (6)).

[0129] The first wearable device (4), the second wearable device (5) and / or the external device (e.g., smart bed (6)) can perform a predetermined action based on the posture change inducing signal (S9).

[0130] In one embodiment, the first wearable device (4), the second wearable device (5), and / or an external device (e.g., a smart bed (6)) may perform an action to induce a change in posture (1400 of FIG. 6 or 1500 of FIG. 6).

[0131] According to one embodiment of the present disclosure, a user's posture can be determined based on a difference in heart rate data, and a change in the user's posture can be induced through various devices based on the determined user's posture.

[0132] Figure 7 illustrates an example of collecting multiple pressure data.

[0133] Referring to FIG. 7, a plurality of pressure sensors (601) may be positioned at different locations and may include pressure sensors (610) that measure pressure applied by a user's body.

[0134] Each pressure sensor (610) can collect pressure data corresponding to the pressure applied by the user's body.

[0135] The pressure sensor (610) may include an FSR sensor (Force Sensitive Resistor sensor; FSR sensor).

[0136] An FSR sensor is a sensor that detects pressure, weight, or touch by utilizing the principle that resistance value decreases when pressure is applied.

[0137] An FSR sensor may include a semi-conductor layer and an active dot layer.

[0138] When no pressure is applied, the semiconductor does not contact the active dot, and when pressure is applied, the semiconductor contacts the active dot.

[0139] If the semiconductor does not contact the active dot, the FSR sensor outputs an infinite resistance value, and if the semiconductor contacts the active dot, the FSR sensor outputs a resistance value less than the reference resistance value.

[0140] Assuming that a reference resistance value is output through the FSR sensor in response to a reference pressure, when a pressure exceeding the reference pressure is applied by the semiconductor coming into contact with the active dot, the FSR sensor can output a resistance value lower than the reference resistance value.

[0141] As the applied pressure value increases, the area size of the semiconductor in contact with the active dot increases, and the FSR sensor can output a smaller resistance value as the contact area size between the semiconductor and the active dot increases.

[0142] Accordingly, when a plurality of pressure sensors (601) include FSR sensors, the server (2) can transmit information on the difference between the first heart rate data and the second heart rate data to the user device (3) based on a resistance value lower than the reference resistance value among the plurality of resistance values ​​output by the plurality of pressure sensors (601).

[0143] The plurality of pressure sensors (601) may also include piezo sensors.

[0144] A piezoelectric sensor is a sensor that can measure the pressure applied to an object by using the piezoelectric effect.

[0145] A piezoelectric sensor can measure the intensity of pressure by detecting the voltage generated by pressure. Assuming that a piezoelectric sensor outputs a reference voltage in response to a reference pressure, a piezoelectric sensor can output a voltage exceeding the reference voltage when pressure exceeds the reference pressure.

[0146] Accordingly, when the plurality of pressure sensors (601) include piezo sensors, the server (2) can transmit information on the difference between the first heart rate data and the second heart rate data to the user device (3) based on the voltage exceeding the reference voltage among the plurality of voltages output by the plurality of pressure sensors (601).

[0147] In one embodiment, a plurality of pressure sensors (601) may be arranged in a predetermined arrangement.

[0148] For example, a plurality of pressure sensors (601) may be arranged in at least one of the first column (L1), the second column (L2), and the third column (L3). The arrangement of the plurality of pressure sensors (601) is not limited thereto and may be arranged in various arrangements.

[0149] Fig. 8 illustrates an example of a flowchart of a sleep management method according to one embodiment. Fig. 9 illustrates a flowchart of transmitting a posture change induction signal based on a plurality of pressure data and a difference value between first heart rate data and second heart rate data according to one embodiment.

[0151] The smart bed (6) can collect multiple pressure data (S12 of FIG. 8 and 2200 of FIG. 9). For example, multiple pressure sensors (601) can collect multiple pressure data.

[0152] The first wearable device (4) can transmit first heart rate data, the second wearable device (5) can transmit second heart rate data, and the smart bed (6) can transmit multiple pressure data to the user device (3) (S13).

[0155] In one embodiment, the server (2) can determine whether to transmit difference value information generated from the difference value based on the difference value between the plurality of pressure data and the first heart rate data and the second heart rate data to the user device (3).

[0156] For example, the server (2) may detect pressure data exceeding a reference pressure value among a plurality of pressure data (example 2300 of FIG. 9), and may determine to transmit difference value information to the user device (3) based on the difference value between the first heart rate data and the second heart rate data being greater than or equal to the first reference value (example 2400 of FIG. 9).

[0157] The server (2) can transmit difference value information to the user device (3) (S16).

[0158] For example, the server (2) may transmit difference value information to the user device (3) based on a determination that the difference value information has been transmitted to the user device (3).

[0159] The user device (3) can generate a posture change induction signal based on the difference value information (S7). The user device (3) can transmit the generated posture change induction signal to the first wearable device (4), the second wearable device (5), and / or the smart bed (6) (S18).

The second reference value means a value greater than the first reference value.

[0161] In one embodiment, the user device (3) may generate a posture change induction signal based on the difference between the first heart rate data and the second heart rate data being greater than or equal to the second reference value (example 2500 in FIG. 9), and transmit the generated posture change induction signal to the first wearable device (4), the second wearable device (5), and / or the smart bed (6).

[0167] According to one embodiment, the first wearable device (4) can determine at least one of the intensity, number of times, and period of vibration based on the posture change inducing signal, and output vibration according to the determined intensity, number of times, and period of vibration.

[0168] For example, if the posture change induction signal corresponds to the difference between the first heart rate data and the second heart rate data, the first wearable device (4) can determine at least one of the intensity, number of times, and period of vibration in proportion to the difference value between the first heart rate data and the second heart rate data, and output vibration according to the determined intensity, number of times, and period of vibration.

[0169] According to one embodiment, the first wearable device (4) can output vibration according to the intensity, number of vibrations, and cycle set by the user.
