Judge whether the posture is standing or sitting.
FIG. 9 is a schematic view showing the above processing flow.

As shown in FIG. 9, in this embodiment, the process of measuring the inclination and the acceleration using the gyro sensor and the acceleration sensor is repeated at predetermined time intervals (steps S110 to S710). In this embodiment, the predetermined time is 200 milliseconds. Also, use the gyro sensor and acceleration sensor that the smartphone has.

When the number of times of the measured inclination and acceleration satisfies a certain number (S210), the present embodiment executes a process of determining the posture of the user using the number of times of the measured inclination and acceleration (S220). In this embodiment, the fixed number is set to 32.

If the posture of the user cannot be determined in step S220, the process of steps 410 to S620, which will be described later, is not performed, and the process of steps S110 to S710 is performed again after step S710 (step S310). In this way, in the present embodiment, the measurement-discrimination process is repeated until the posture of the user can be discriminated.

On the other hand, when it is determined that the posture of the user is walking, standing, or sitting, the processes of steps S410 to S620 are performed.

In this case, it is determined whether or not the task is executed as a foreground task of the smartphone (step S410), and in the case of the foreground task, the posture determined in step S220 is the immediately preceding determination result, that is, the step in the process of the previous steps S110 to S710. It is compared whether or not it is the same as the determination result of S220 (step S420). If the result is not the same as the previous determination result, the subsequent steps S510 to S620 are not performed, and the process of the next steps S110 to S710 is repeated through step S710 (step S420). In the present embodiment, the comparison in step S420 is performed only when the determination result in S220 is standing or sitting. That is, in the determination of the standing position or the sitting position in the present embodiment, when the posture is executed as the foreground task of the smartphone, the posture of the user is determined when it can be determined that the posture is the same two or more times in a row. Confirmed as.

When the posture is confirmed, or when it is not a foreground task, that is, when it is executed as a background task, it is determined whether or not the time point is within the working hours of the user, and if it is outside the working hours, step S110. The processing of ~ S710 is completed (steps S510 and S520).

Next, when the present embodiment is executed as a background task of the smartphone, the program is stopped for a predetermined period (steps S610 and S620), and the process of the next steps S110 to S710 is repeated through step S710.

FIG. 10 is a conceptual diagram showing a detailed processing flow of step S220 in FIG. As shown in FIG. 10, in step S220, it is determined whether or not the user holds the smartphone, that is, holds it in his / her hand, from the inclination of the smartphone measured in step S110 (step S810).

Next, in step S820, the sum and variance of the horizontal acceleration and the sum and variance of the gravity direction acceleration are obtained by calculation from the acceleration measured in step S110, respectively. Depending on the value of the acceleration sensor used in the calculation, the above calculation may be subjected to various processing. For example, when using an accelerometer that acquires a negative value as the measured acceleration value, when calculating the sum, first obtain the absolute value of the accelerometer value, and then calculate the sum of the absolute values. You may ask. In the present embodiment, since the posture is determined every 32 times of measurement in step S110 as described above, in step 820, the sum and variance are calculated from the measured values for the 32 times.

After acquiring the value to be determined in steps S810 and S820 described above, the processes of steps S831 to S891 for determining whether the user is in a walking, standing, or sitting posture are performed. Steps S831 to S891 include a first determination process (steps S831, S841), a second determination process (steps S841, S842), a third determination process (steps S861, S862), and a fourth determination process. It is composed of (steps S871 and S872) and a five-step determination process of the fifth determination process (steps S881 to S891).

The first determination process is a process of determining whether or not the user is walking from the sum of the horizontal acceleration and the gravitational acceleration. Specifically, when the sum of the horizontal acceleration and the sum of the gravitational acceleration both exceed a predetermined threshold value, it is determined to be a walking posture (steps S831 and S832). In this embodiment, 2 (unit is gravitational acceleration) is used as the threshold value.

If the first determination process described above does not determine walking, the second determination process determines whether or not the user is in a sitting posture. Specifically, the sitting posture is determined when both the dispersion of the horizontal acceleration and the dispersion of the gravity direction acceleration are less than a predetermined threshold value (steps S841 and S842). In this embodiment, 0.0000003 is used as the threshold value.

If the posture of the user cannot be determined by the above-mentioned first and second determination processes, the posture of the user cannot be determined depending on whether or not the horizontal acceleration is within a predetermined range in steps S851 and S852. Judge whether or not. In this embodiment, −0.1 to 0.1 (unit is gravitational acceleration) is used as the predetermined range, and if the acceleration measured in step S110 is outside the above range, it is determined that the posture cannot be determined. ..

If it is not determined that the determination is impossible in step S851 described above, it is determined by the third determination process whether or not the user is in the sitting posture. Specifically, when the sum of the horizontal acceleration and the sum of the gravitational acceleration are less than a predetermined threshold value, the user determines that the posture is in the sitting position. In this embodiment, 0.05 is used as the threshold value for horizontal acceleration and 0.28 is used as the threshold value for gravitational acceleration (both units are gravitational acceleration).

If the posture of the user cannot be determined by the third determination process described above, it is determined by the fourth determination process whether or not the user is in a standing posture (steps S871 and S872). In steps S871 and S872, in addition to the sum of the horizontal and gravitational accelerations, the determination result of step S810, that is, whether or not the user is holding the smartphone is used to determine whether or not to stand. .. In the present embodiment, the total horizontal acceleration exceeds the threshold value of 0.08 (unit is gravitational acceleration), and the total sum of gravitational acceleration is less than the threshold value of 0.2 (unit is gravitational acceleration). If there is, and the user is not holding the smartphone, it is determined to be standing.

If the posture of the user cannot be determined by the fourth determination process described above, the present embodiment determines the posture of the user by the fifth determination process (steps S881 to S891). The fifth determination process branches depending on the determination result in step S810 described above, that is, whether or not the user holds the smartphone (step S881).

The determination process when the user is holding the smartphone is steps S882 to S888. When the user is holding the smartphone, it is first determined whether or not the previous determination result is walking (S882). When the previous determination result is walking, it is determined that the user is in the sitting posture (S883).

On the other hand, when the previous determination result is not walking, the sum of the horizontal acceleration and the sum of the gravitational acceleration are compared with a predetermined threshold value to determine whether or not the user is in the sitting posture (step S884). , S885). In the present embodiment, the sum of horizontal acceleration is less than the threshold value of 0.2 (unit is gravitational acceleration), and the sum of gravity direction acceleration is the threshold value of 0.22 (unit is gravitational acceleration). ), It is judged that the user is in the sitting position.

If it cannot be determined to be in the sitting position in step S884 described above, the sum of the horizontal acceleration and the sum of the gravitational acceleration are compared with a predetermined threshold value to determine whether or not the user is in a standing position. (Steps S886 to S888). In the present embodiment, the total horizontal acceleration is larger than the threshold value of 0.16 (unit is gravitational acceleration), and the total sum of gravitational acceleration is 0.26 (unit is gravitational acceleration). If it is less than, it is judged to be standing, and if it cannot be judged to be standing, it is judged to be undecidable.

If the user is not holding the smartphone, the posture of the user is determined by the processes of steps S889 to S891. In this case, if this embodiment is executed as a foreground task of a smartphone, it is determined that the posture determined last time is continued, and if it is executed as a background task, it cannot be determined. Judge.

The above is the flow of the process for determining the posture of the user in this embodiment. In the present embodiment, the posture of the user is determined only by using the inclination measured by the gyro sensor and the acceleration measured by the acceleration sensor, but even if a value measured by another device is added to this. Good. In addition, the above-mentioned threshold value may be appropriately selected depending on the usage status of the smartphone, the behavior pattern of the user, and the like.

In the program according to the present embodiment, the amount of activity in each posture is measured as calories burned based on the set value input on the setting screen W21 and the posture determined by the above-mentioned processing. The measured calorie consumption is displayed in the posture area 310 as a value in METS units, and the cumulative value of calories burned during working hours is displayed in the total calorie consumption area 320 as a value in kilocalories.

In the present embodiment, the above-mentioned activity amount is measured only based on the posture, but in carrying out the present invention, complex activity amount measurement may be performed using information other than this. For example, a beacon device capable of wireless communication with a smartphone is placed in advance in a place where it is expected that the person is in a posture or exercise other than walking, standing, or sitting, such as a specific room or stairs. When the beacon device is detected, the activity amount may be measured based on the location of the beacon device. In this case, the beacon device is preferably a Bluetooth® device.

Further, in the program according to the present embodiment, the display of the CoST area 330 and the performance level area 340 changes based on the time during which one posture is continued. When the sitting posture is continued, the duration is displayed as CoST in the CoST area 330. At this time, if the duration exceeds a predetermined threshold value, the warning icon 333 is displayed. The time during which the sitting or standing position is continued is used for measuring the performance level described later.

The calorie graph screen W41 is a screen that displays the calorie consumption of the user during working hours in a graph format, and is a screen that transitions by tapping or the like from the activity amount screen W31 to the total calorie consumption area 320. As shown in FIG. 5, the calorie graph screen W41 is composed of a date area 410 and a graph area 420.

The date area 410 is an area for displaying which date the graph displayed in the graph area 420 is the measurement result of which date, and the date label 411, the previous day button 412, and the next day button 413 are displayed.

The date label 411 is a label indicating which date the measurement result of the graph displayed in the graph area 420 is. The graph displayed in the graph area 420 can be changed by pressing the previous day button 412 or the next day button 413.

The graph area 420 is a screen for displaying the measurement result of the day displayed in the date area 420, and is a calorie graph 421, a target value 422, a posture graph 423, a sitting icon 424, a sitting time 425, a standing icon 426, and a standing position.
