  For example, when there is a proportional relationship between the measured momentum and the X (second index) of the music to be selected, the X (second index) of the music to be selected when the momentum is large has a small momentum. A relatively large value may be set in comparison with X (second index) of the music to be selected.

  Also, for example, the amount of exercise is classified into a plurality of categories such as very small, small, medium, large, and very large, and the amount of X-second table defining the X (second index) range of the music to be selected for each category. May be prepared.

  The value associated with the pulse is set in Y (first index) 230 to have a predetermined relationship (for example, a functional relationship) between the pulse and the Y (first index) 230 value of the selected music.

You may make it keep.

  In the present embodiment, as shown in FIG. 2A, a virtual music space is set in which the X axis indicates activity, the Y axis indicates excitement, and the Z axis indicates time. Based on the values of the added indexes X, Y, and Z, the music is arranged in the music space.

  FIG. 2 (B) shows the relationship between X (activity (correlation with momentum)), Y (excitation (correlation with pulse)) and user's “mood” in the XY plane of the music space (this implementation) This relationship is estimated in the form of That is, assuming that 0 is a normal momentum (X-axis) pulse (Y-axis), a region I where momentum (X)> normal momentum (0) and pulse (Y)> normal pulse (0) is: Estimate that “user is exercising” 310. The region II where the momentum (X)> normal momentum (0) and pulse (Y) <normal pulse (0) is estimated to be “the user is tired” 320. The region III where the momentum (X) <normal momentum (0) and pulse (Y)> normal pulse (0) is estimated to be “the user is frustrated” 330. The region IV where the momentum (X) <normal momentum (0) and pulse (Y) <normal pulse (0) is estimated to be “user resting state” 340.

  FIG. 2C is a diagram showing the relationship between time and the mood of the user. In this embodiment, the time and the mood pattern of the user can be set in advance. For example, it is possible to specify a time zone for one day and set the user's mood as “UP” or “DOWN” according to the time zone. In this way, it is possible to select a music piece that reflects the “mood” set by the user according to the time.

  FIG. 3 shows an example of the composition of music data stored in the music data storage unit. Each piece of music data 250 is stored corresponding to the music identification ID 210, and X (second index) 220, Y (first index) 230, and Z (third index) 240 are added to the music data. Has been.

  Here, the X (second index) 220 of each music piece is an index that evaluates the music piece corresponding to the element (for example, tempo, rhythm, genre, etc.) extracted from the viewpoint of the relationship with the amount of exercise. Is set.

  In addition, the Y (first index) 230 of each musical piece is set with an index that evaluates the musical piece corresponding to the element (for example, tempo, rhythm, genre, etc.) extracted from the viewpoint of the relationship with the pulse. Yes.

  In addition, the Z (third index) 240 of each music corresponds to the music elements (for example, tempo, rhythm, genre, etc.) extracted from the viewpoint of the relationship with the user's mood set corresponding to the time. An index for evaluating the music is set.

  FIG. 4 is a flowchart showing the music selection process of the present embodiment.

  First, a setting input for the relationship between the time and the user's mood is received, and a time condition that defines the relationship between the time and the value of the third index to be extracted is set based on the setting input (step S10).

  Next, when contact with the pressing portion for acquiring pulse information is detected, the processing of steps S20 to S60 is performed (step S20).

  Next, the pulse group is measured based on the information acquired through the pressing unit (step S30).

  In step S40, the amount of exercise measured at the timing of acquiring the pulse group is acquired.

  Next, the measurement date and time of the pulse group is acquired (step S50).

  Then, the first, second, and third index values to be the target range are determined according to the pulse, the amount of exercise, the time and the extraction conditions set in relation to the time, and the index values belonging to the determined target range Is extracted and reproduced (step S60).

  FIG. 5 is a flowchart showing detailed processing of music selection according to this embodiment.

  First, the first, second, and third index values that are the center points of the target range in each of the extraction conditions set in relation to the pulse, the momentum, and the time are determined (step S110).

Next, a predetermined range including the center point is determined as the target range, and the music having the closest position determined by the X, Y, and Z values of the center point and the music is selected and reproduced from the determined target range. (Step S120).
Here, when an input of a cancel key from the user is accepted, another music piece belonging to the target range is selected and reproduced (steps S130 and S140).

When the input of the cancel key from the user is accepted again, the center point is changed to a position rotated by a predetermined angle with respect to the origin 0, and the processing from step S110 is repeated (steps S150 and S160).
The center point may be changed to a position rotated by a predetermined angle with respect to the origin 0. For example, the center point may be inverted symmetrically with respect to the origin 0, or may be inverted with respect to a predetermined axis. Or may be rotated by a predetermined angle unit within a plane including the center point and the origin 0.

  FIG. 6 is a functional block diagram for explaining the configuration of the pulse measurement unit of the present embodiment.

  You may make it comprise the pulse measurement part of this Embodiment as a switch with a built-in sensor. The sensor built-in switch 110 includes a switch 120 that detects contact with the pressing unit and outputs a contact detection signal 128, and a pulse measuring unit (50, 40, 30) that measures the pulse of the target that has touched the pressing unit.

  The pulse measurement unit (50, 40, 30) includes a sensor 130 disposed at a position where a physical quantity, a chemical quantity or a physical / chemical property necessary for measuring given information of a target can be detected, The biological information of the human body is measured using the contact detection signal 128 to the pressing unit (switch) as a start trigger.

  The sensor 130 may be any sensor that senses human pulse information, and may be, for example, a photodetector or a photosensor.

  Measuring the pulse information information of the human body using the contact detection signal as a start trigger may be, for example, when the sensor itself is turned on by the contact detection signal to perform sensing, or the sensor itself is always sensing, There may be a case in which a measurement range is determined using the detection result of the sensor based on the detection signal.

  The pressing unit may be configured to be operated by a user's finger, and the sensor may be configured to measure a pulse of the finger that has touched the pressing unit.

  In the case where the sensor 130 is a light detection type, a disturbance prevention unit 140 may be included to prevent disturbance due to external light entering through the gap between the finger and the pressing unit.

  Further, the sensor 130 and a circuit necessary for driving the sensor (sensor auxiliary device 150) may be incorporated in the switch.

According to the present embodiment, since the sensor is inside the switch, even if an unnatural action such as placing a finger on the sensor is not performed, it is possible to “push” the switch. There is an effect that the necessary pulse measurement can be performed in the meantime.

  By measuring at the timing when the switch is pressed, it can be ensured that the target is present at a position where sensing is possible, so that it is guaranteed that correct measurement is being performed.

  FIG. 7 is a diagram for explaining an example of the configuration of the pulse measuring unit.

  The pulse measurement sensor built-in switch 220 that functions as a biological information measurement unit includes a photosensor 130, an LED 150 that functions as a sensor auxiliary device, and a disturbance light prevention rubber 140 that functions as a disturbance prevention device.

  The LED 150 is connected to an LED driving power source 152 and is disposed at a position where light can be irradiated to a target (here, a human finger 200) in contact with the surface of the switch.

  LED150 functions as a light irradiation part which irradiates the light for a detection with respect to the target which is contacting the pressing part.

  The photosensor 130 is connected to a photosensor power supply 132 and is disposed at a position where it can receive reflected light from a target (here, a human finger 200) that is in contact with the surface of the switch.

  The pressing part 122 (the part touched by the finger on the surface of the switch) of the pulse measuring sensor built-in switch 220 is configured to be operated by the user's finger 200, and the sensor (here, the photo sensor 130) The light reflected on the hemoglobin 210 of the touched finger 200 is sensed.

  A light passing part 124 is provided between the pressing part 122 and the sensor (here, the photo sensor 130). The photo sensor 130 receives the light that has passed through the light passing part 124, and comes into contact with the pressing part 122 based on the amount of light received. Measure the finger pulse.

  Here, a disturbance prevention unit (disturbance light prevention rubber 140) for preventing external light (disturbance light 142) from entering the light passage part 124 from the gap between the finger 200 and the pressing unit 122 may be included.

  The disturbance prevention unit can be realized by arranging an elastic body such as rubber around the pressing unit in order to prevent external light (disturbance light 142) from entering the light passage unit 124, for example.

  For example, the light 154 may be emitted from the LED by a contact detection signal generated when the pressing unit 122 is pressed. The light 154 that has passed through the light passage part 124 is reflected when it hits the hemoglobin 210 contained in the blood of the finger 200 placed on the pressing part 122, and the reflected light 156 passes through the light passage part 124 again, and this reflected light is reflected. The photo sensor 130 receives the light 156. The photosensor is activated by a contact detection signal, detects the amount of reflected light received for a given period, and calculates a pulse as a measurement value from the amount of received light.

  Here, for example, the light irradiation unit (here, the LED 150) may emit near infrared rays, and the photosensor 130 may receive near infrared rays. However, in this case, ambient light tends to pass through the finger.

  The light irradiation unit (here, LED 150) may emit blue light, for example, and the photosensor 130 may receive blue light. As described above, the sensor includes a light irradiation unit that irradiates the target that is in contact with the pressing unit, and the sensor is configured to receive reflected light of the light irradiated from the light irradiation unit with respect to the target. In this case, if the light irradiating unit emits blue light as detection light, the light irradiating unit is less susceptible to disturbance light.
