The cellular phone 1 is a so-called foldable type, and a housing 20 is constituted by a first housing 21 and a second housing 22 that are pivotally supported at one end in a longitudinal direction. 2A shows a state in which the first housing 21 and the second housing 22 are opened (open state), and FIG. 2B shows a state in which the first housing and the second housing 22 are closed. (Closed state). On the inner surface of the first housing 21, operation keys for turning on / off the power, on-hook / off-hook, and operation keys corresponding to numbers 0 to 9 (collectively referred to as operation keys 23) are arranged vertically and horizontally. It is arranged. On the other hand, a liquid crystal display 24 of the display unit 8 which will be described later is disposed on the inner surface of the second housing 22, and an antenna 25 of the transmission / reception unit 2 projects from the distal end portion of the second housing 22 so as to extend and contract. ing.

  A circuit configuration of the mobile phone 1 is shown in FIG. The cellular phone 1 performs signal processing on a transmission / reception unit 2 that transmits and receives a radio signal using radio waves as a medium via an antenna 25, a microphone 3 and a speaker 4, and an audio signal output from the microphone 3, and also receives a reception signal. An audio signal processing unit 5 that processes and sounds a sound from the speaker 4, a modulation / demodulation unit 6 that performs modulation / demodulation processing of the audio signal, an operation input reception unit 7 that receives an operation input by the operation keys 23, a liquid crystal display 24, and its drive A display unit 8 having a circuit; a memory unit 9 including a nonvolatile memory; a state detection unit 10 that detects an open state and a closed state of the housing 20; an infrared communication unit 11 that performs wireless communication using infrared as a medium; , An acceleration detection unit 12 that detects acceleration, and a control unit 13 that controls each unit using a microcomputer as a main component. In addition, although illustration is abbreviate | omitted, the power supply circuit part which produces the operating power supply of each part using a secondary battery as a power supply is also provided.

  The received signal received by the antenna 25 is amplified and frequency-converted by the transmission / reception unit and output to the modulation / demodulation unit 6. The modem 6 demodulates the frequency-converted received signal and outputs it to the audio signal processor 5. The audio signal processing unit 5 decodes the audio signal from the demodulated signal, outputs the audio signal to the speaker 4, and sounds the audio from the speaker 4. On the other hand, the audio signal input from the microphone 3 is encoded by the audio signal processing unit 5, modulated by the modulation / demodulation unit 6, and transmitted from the transmission / reception unit 2 via the antenna 25.

  The control unit 13 includes a call processing function for making a call according to a call number received by the operation input receiving unit 7, an incoming call process function for receiving a call according to a received signal received by the transmission / reception unit 2, and an operation input receiving unit. 7, a display processing function for displaying various information such as the calling number received in 7 and the telephone number stored in the memory unit 9 on the display unit 8, an infrared communication processing function for controlling the infrared communication unit 11 to perform infrared communication, In addition to a conventionally known function such as a power saving processing function for turning on / off the backlight of the display unit 8 according to the detection result of the state detection unit 10, the amount of physical activity of the user is determined from the acceleration detected by the acceleration detection unit 12. It has a calculation processing function for calculating.

  The acceleration detection unit 12 includes, for example, a semiconductor acceleration sensor configured to detect acceleration in the directions of three axes (X axis, Y axis, Z axis) of a three-dimensional orthogonal coordinate system, and detects acceleration for each axis direction. The value is output to the control unit 13. The control unit 13 calculates a variation average (standard deviation value) of acceleration for a certain time tw, and calculates a physical activity intensity (hereinafter abbreviated as activity intensity) wi from the variation average (or an integrated value thereof). Processing.

  The calculation process of the activity intensity wi is a process of calculating according to the relational expression between the oxygen consumption amount measured by changing the mobility intensity by the expiration gas measuring device and the acceleration dispersion value. This calculation process will be described with reference to FIG. A combined value of fluctuations of each axis for a certain fixed time tw [seconds] is calculated. When the time average (standard deviation) of the combined value is Sw, the following formula is obtained.

  Here, axk, ayk, and azk indicate acceleration sampling values at the k-th for a fixed time tw [seconds], and bx, by, and bz indicate average values for a fixed time tw [seconds].

Therefore, the value of the activity intensity wi at the predetermined time tw is obtained from the data shown in FIG.
That is, the figure obtained by least square approximation of the points shown on the scatter diagram showing the relation between the points plotted in FIG. 4 (acceleration fluctuation average value) and METs values (activity intensity in units of METs) described later. The relationship of the four straight lines is represented by y = ax + b and the correlation function R = 0.92.
(Y: acceleration fluctuation value x: METs value)
When the acceleration fluctuation value y, that is, the time average value Sw of the above-described composite value is obtained, the activity intensity wi (METs value) for a predetermined time tw is obtained from the following equation.
wi = αSw + β (2)
Here, α and β are coefficients in the relational expression obtained between the oxygen consumption amount measured by changing the luck intensity by the breath gas measuring device and the acceleration dispersion value.

  The value of activity intensity is based on the “METs” value used in the American Sports Medicine Association, which indicates how many times the energy consumption during exercise is greater than the energy consumption during rest.

Moreover, in the said method, 4 to 15 seconds is a suitable value as the fixed time tw. However, in the case where the calculation time width of the activity intensity is increased, for example, when it is set to 1 minute or more, after taking the time average Sw, The activity intensity wi is calculated. Therefore, if the new time width is Tw,
wi = α (ΣSw × (Tw / tw))) + β (2) ′.

  The activity intensity wi may be calculated using the integrated value of the fluctuation average or the time integrated value in a time longer than a predetermined time.

  The control unit 13 stores the obtained activity intensity in the memory unit 9.

  Moreover, the control part 13 is provided with the activity intensity | strength setting function which sets the predetermined optimal activity intensity | strength compared with the activity intensity calculated | required as mentioned above as follows.

  Specifically, the maximum amount of oxygen (ml / kg / min) that can be consumed per minute per kilogram of Japanese body weight determined by the “Ministry of Health and Welfare Exercise Requirements Formulation Committee” established in 1989 Using the estimated value (Table 1) and the maintenance target (Table 2), a predetermined optimum activity intensity is determined as follows.

  Life activity intensity I refers to those who are engaged in office work or similar work, full-time housewives who do not have infants, etc. II is intended for persons engaged in the manufacturing and service industries, and for housewives who take care of infants.

  Thus, based on Table 1 and Table 2, athletic ability levels are determined in three stages (I to III), and predetermined optimum activity intensity (optimum activity intensity Aa) corresponding to each athletic ability level is expressed by the following formula (3 ) The correspondence between the athletic ability level and Tables 1 and 2 is as follows.

Motor ability level I → Living activity intensity I
Motor ability level II → Maintenance target value Motor ability level III → Living activity intensity II
Aa = VO _{i_age} /2/3.5 (3)
VO _{i_age} is the value of the maximum oxygen intake in each age _group of each exercise ability level I to III.

  Next, a method for setting a predetermined optimum activity intensity according to a user (a person to be measured) will be described.

  First, the values in the table (Table 3) determined by the expression (3) are stored in the memory unit 9 in advance on the manufacturer side.

  Next, when the user measures the amount of physical activity using the mobile phone 1, the operation intensity setting mode is set by operating the operation key 23 of the operation input receiving unit 7. In this mode, a screen for the user to input his / her age, gender, and self-reported exercise level is displayed on the liquid crystal display 24 under the control of the control unit 13, and the user confirms this display screen while checking the age and gender. Enter the exercise level. This screen is a screen for selecting each of them, and the age, sex, and exercise level can be selected by operating the operation keys 23.

  When the input is confirmed, the control unit 13 reads the set value corresponding to the corresponding exercise level from the table (Table 3) stored in the memory unit 9 based on the input information. Is registered and set in the memory unit 9 as the optimum activity intensity.

  After the setting, when the user carries the mobile phone 1 of the present embodiment and sets the operation mode to the use mode by operating the operation key 23 of the operation input receiving unit 7, the control unit 13 receives data from the acceleration detection unit 12. The activity intensity calculation is started based on the above formulas (1) and (2), and the calculated activity intensity value is compared with the set activity intensity value. The processing for calculating the duration of the exercise time equal to or higher than the exercise level corresponding to the activity intensity and the accumulated time thereof is performed and stored in the memory unit 9.

  By displaying these information on the liquid crystal display 24 in real time, the user's own exercise level can be presented to the user.

  The amount of physical activity obtained by the control unit 13 from the output value of the acceleration detection unit 12 is accumulated in the exercise time for each activity intensity and stored in the memory unit 9. The stored exercise time for each activity intensity is displayed on the liquid crystal display 24 of the display unit 8 as shown in FIGS. 5A to 5C under the control of the control unit 13. The bar graph 100 in FIG. 5 (a) shows an example of displaying exercise time for each activity intensity. For example, the activity intensity is an accumulation of the exercise time of the day in 11 stages from "1" to "11". One scale is shown in 5 minutes. Further, the exercise time of the predetermined optimum activity intensity set is indicated by a bar graph 101, and if the predetermined optimum activity intensity is continued for 5 minutes, for example, it will increase by one scale, and if all the scales are displayed, This means that they have performed a predetermined exercise for 60 minutes. It can be a goal for a predetermined exercise amount of the day. The numbers in the bar graph 100 indicate the time, and whether the time is in the morning, afternoon, or day is displayed in the display field 102.

  The display area 103 displays the upper and lower levels of the optimum activity intensity value determined from the input age, sex exercise level, etc., for example, the “white” scale indicates the upper level as “black”. "Shows the lower level on the scale." The past exercise history is displayed in the bar graph 100 or the bar graph 101 by incrementing or decrementing the exercise date displayed in the exercise date display field 104 by operating a predetermined operation key 23 of the operation input receiving unit 7. It is also possible to use a past history. The display column 105 is a column for displaying energy consumption, the time of performing a predetermined exercise, the number of steps, etc., and the unit is displayed in the display column 104 on the right side. A display column 107 is a display column for the current time, and displays the time measured by the built-in clock function of the control unit 13.

  FIG. 5B shows an example in which a predetermined exercise time is displayed as a bar graph 100 and the accumulated time [minutes] is displayed in the display column 105.

  FIG. 5C shows the activity intensity and exercise time converted into energy consumption, the energy consumption for each hour is displayed as a bar graph 100, and the total energy consumption [kcal] is displayed in the display column 105.

  In both the example of FIG. 5A and the example of FIG. 5B, past history data can be read and displayed by changing the display date of the display column 104 by operating the operation key 23 of the operation input receiving unit 7. it can.

  In the control unit 13, when the operation input receiving unit 7 receives an operation of a specific operation key 23, the modulation / demodulation unit 6 modulates the physical activity amount read from the memory unit 9 and transmits a radio signal from the transmission / reception unit 2. It can be transmitted to the base station, or can be transmitted from the infrared communication unit 11 as an infrared signal.

  Here, when the mobile phone 1 is being used (for example, during a call), the acceleration detected by the acceleration detection unit 12 may be greater than the acceleration due to the user's physical activity. If used and calculated, the measurement accuracy of the amount of physical activity will decrease. In addition, when the case 20 is in an open state other than during a call, there is a high possibility that the user is performing some operation on the mobile phone 1, and in such a case, the measurement accuracy of the amount of physical activity is reduced. There is a fear. Therefore, during a call (a period in which the audio signal processing unit 5 performs signal processing) and in a period in which the state detection unit 10 detects an open state, the control unit 13 uses the acceleration detection value of the acceleration detection unit 12 as the body. It is desirable to improve the measurement accuracy of physical activity amount so that it is not used in the calculation of activity amount.

  In the present embodiment, a foldable mobile phone is illustrated, but it goes without saying that the technical idea of the present invention can be applied to a so-called slide-type mobile phone as shown in FIG. In the slide type mobile phone, as shown in FIG. 6A, the first housing 21 and the second housing 22 are overlapped in the front-rear direction (vertical direction in FIG. 6), and FIG. ), The first housing 21 and the first housing 21 are slidable along the direction intersecting the front-rear direction between the first housing 21 and the open state where part of the second housing 22 does not overlap in the front-rear direction.
