(Massage chair operation)
Hereinafter, the operation of the massage chair according to one embodiment of the present invention will be described with reference to the drawings. FIG. 13 is a flowchart showing the operation of the massage chair 100 according to one embodiment of the present invention.

  As shown in FIG. 13, in step 10, the user turns on the massage chair 100.

  In step 30, the massage chair 100 has the backrest 10 so that the angle a formed by the backrest surface 10a (line 10L) and the seating surface 20a (line 20L) is a predetermined initial angle (for example, about 128 °). Change the tilt of.

  In step 50, the massage chair 100 is configured so that the angle c formed by the seating surface 20a (line 20L) and the footrest part 30 (line 30L) is a predetermined initial angle (for example, about 110 °). Change the tilt of.

  In Step 70, the massage chair 100 is configured so that the angle d formed by the footrest 30 (line 30L) and the sole 40 (line 40L) is a predetermined initial angle (for example, about 90 °). The inclination of the unit 40 is changed.

  In step 90, the massage chair 100 is positioned so that the angle b formed by the seat surface 20a (line 20L) and the line 100L substantially parallel to the ground contact surface Sg is a predetermined initial angle (for example, about 30 °). The inclination of the unit 20 is changed. The massage chair 100 finely adjusts the inclination of the seat 20 based on the user's biological information acquired from the remote controller 200. The details of the seating surface angle changing process will be described later (see FIG. 14).

  In step 110, the massage chair 100 starts a massage process. Specifically, the massage chair 100 detects the user's shoulder position in a state where the user is seated on the massage chair 100, that is, in a state where the user's back is supported by the backrest surface 10a.

  In step 130, the massage chair 100 selects a massage course based on the user's biological information acquired from the remote controller 200. For example, as illustrated in FIG. 7, the massage chair 100 selects a massage course according to the difference between the calculated HI power value and the average HI power value.

  In step 150, the massage chair 100 starts the massage course selected in step 130 and massages the user.

  In step 170, the massage chair 100 changes the content of the massage course based on the user's biological information acquired from the remote controller 200. For example, as shown in FIG. 9, the massage chair 100 specifies the psychological state of the user based on biological information such as the amount of change in GSR, the amount of change in skin temperature, and the amount of change in heart rate. Subsequently, as shown in FIG. 10, the massage chair 100 changes the content of the massage course according to the identified psychological state of the user and the type of the massage course selected in step 130.

  In step 190, the massage chair 100 determines the evaluation result of the massage effect given to the user based on the pre-massage biometric information and the post-massage biometric information. For example, as shown in FIG. 12, the massage chair 100 has a massage effect according to the comparison result between the pre-massage HI power value and the post-massage HI power value and the type of the massage course selected in step 130. The evaluation result is determined. In addition, the massage chair 100 displays the massage effect evaluation result on the display unit 230 of the remote controller 200.

  In step 92, the massage chair 100 acquires the user's biological information from the remote controller 200. For example, the massage chair 100 acquires a heart rate as the biological information of the user.

  In Step 93, the massage chair 100 calculates the degree of relaxation of the user based on the user's biometric information acquired in Step 92. For example, the massage chair 100 calculates the HI power value as the degree of relaxation of the user based on the heart rate acquired as the user's biological information.

  In Step 94, the massage chair 100 finely adjusts the inclination of the seat portion 20 to change the angle b formed by the seat surface 20a (line 20L) and the line 100L. Specifically, the massage chair 100 finely adjusts the inclination of the seat portion 20 so that the angle b is reduced by about 1 °.

  In step 95, the massage chair 100 acquires the user's biological information from the remote controller 200 as in step 92.

  In step 96, the massage chair 100 calculates the degree of relaxation of the user based on the user's biometric information acquired in step 95 as in step 93.

  In step 97, the massage chair 100 determines whether or not the degree of relaxation of the user has increased. The massage chair 100 proceeds to the process of step 99 when the degree of relaxation of the user has increased, and proceeds to the process of step 98 when the degree of relaxation of the user has not increased.

  In step 98, the massage chair 100 does not increase the degree of relaxation of the user even if the inclination of the seat 20 is finely adjusted. Therefore, the angle b formed by the seat surface 20a (line 20L) and the line 100L, that is, The inclination of the seat part 20 is restored. Specifically, the massage chair 100 finely adjusts the inclination of the seat 20 so that the angle b increases by about 1 °.

  In step 99, the massage chair 100 determines whether or not the angle b formed by the seat surface 20a (line 20L) and the line 100L has reached a limit value (for example, 25 °). Further, the massage chair 100 ends the seat surface angle adjustment process when the angle b has reached the limit value, and returns to the process of step 94 when the angle b has not reached the limit value.
