(Wearable devices as portable electronic devices)
First, as an exercise support device (detection device) used in an exercise support system or the like, for example, a wearable device (list device) as a portable electronic device provided with a pulse wave sensor or a body motion sensor attached to a user's wrist is exemplified. This will be described with reference to FIGS. 1, 2, 3, and 4. FIG. 1 is an external view showing a schematic configuration of a wearable device as a portable electronic device. FIG. 2 is an external view showing an example of wearing a wearable device. FIG. 3 is a cross-sectional view illustrating a configuration example of a wearable device. FIG. 4 is a functional block diagram illustrating a configuration example of the wearable device.

  The wearable device 200 as a portable electronic device includes a pulse wave sensor (optical sensor unit 40) for acquiring pulse wave information as user's biological information and a body motion sensor unit for acquiring user motion information (body motion information). 170 is provided. Further, the wearable device 200 includes a GPS (Global Positioning System) as an example of a positioning system using a position information satellite called a Global Navigation Satellite System (GNSS) that acquires user position information. ) Satellite positioning unit 160 is provided. The wearable device 200 may be a wearable device that is worn on another part of the user such as a neck or an ankle.

  The pulse wave sensor (the optical sensor unit 40) can acquire pulse wave information such as the pulse rate. For example, a photoelectric sensor is used as the pulse wave sensor. In this case, a method of detecting reflected light or transmitted light of light irradiated on the living body with the photoelectric sensor can be considered. Since the amount of light absorbed and reflected by the living body varies depending on the blood flow in the blood vessel, the sensor information detected by the photoelectric sensor becomes a signal corresponding to the blood flow, etc. Information about beats can be acquired. However, the pulse wave sensor is not limited to a photoelectric sensor, and other sensors such as an electrocardiograph and an ultrasonic sensor may be used.

  The body motion sensor unit 170 is a sensor that detects a user's body motion. As the body motion sensor unit 170, as shown in FIG. 4, it may be possible to use an acceleration sensor 55, an angular velocity sensor (not shown), an orientation sensor (geomagnetic sensor) 56, a pressure sensor (atmospheric pressure sensor) 57, or the like. Other sensors may be used.

  GPS is also called a global positioning system, and is a satellite positioning system for measuring the current position on the earth based on a plurality of satellite signals. The GPS satellite positioning unit 160 has a function of performing positioning calculation using GPS time information and orbit information to acquire user position information, and a time correction function in a clock function.

  The satellite positioning unit 160 (see FIG. 4) provided in the wearable device 200 receives radio waves (satellite signals) from GPS satellites, corrects the internal time, and performs positioning calculation to acquire position information. It has a function.

  A GPS satellite is an example of a position information satellite that orbits a predetermined orbit in the sky above the earth. The GPS satellite transmits a high-frequency radio wave on which a navigation message is superimposed, for example, a radio wave having a frequency of 1.57542 GHz (L1 wave) to the ground. In the following description, a radio wave of, for example, 1.57542 GHz on which a navigation message is superimposed is referred to as a satellite signal. The satellite signal is a right-handed circularly polarized wave.

  Currently, there are 32 GPS satellites. In order to identify which GPS satellite the satellite signal is transmitted from, each GPS satellite superimposes a unique pattern of 1023 chips (1 ms period) called a C / A code (Coarse / Acquisition Code) on the satellite signal. In the C / A code, each chip is either +1 or -1, and looks like a random pattern. Therefore, by correlating the satellite signal and the pattern of each C / A code, the C / A code superimposed on the satellite signal can be detected. In this way, it is possible to obtain a satellite number that identifies from which GPS satellite the satellite signal was transmitted.

  GPS satellites are equipped with atomic clocks. The satellite signal includes extremely accurate GPS time information measured by an atomic clock. A slight time error of the atomic clock mounted on each GPS satellite is measured by the control segment on the ground. The satellite signal also includes a time correction parameter for correcting the time error. Wearable device 200 receives a satellite signal (radio wave) transmitted from one GPS satellite, and acquires time information using GPS time information and time correction parameters, which are GPS satellite time information included therein. can do. The satellite signal includes ephemeris (precise satellite orbit information) indicating the position of the GPS satellite in the orbit and almanac.

  Here, the ephemeris (precision satellite orbit information) is a function of time that expresses the position of one satellite with high accuracy, and has more parameters for representing the orbit than almanac, so the accuracy of the orbit is high. Acquisition takes approximately 30 seconds to 1 minute. Almanac also shows the approximate position of all satellites as a function of time. Acquisition takes 10 minutes or more.

  Wearable device 200 can perform positioning calculation using GPS time information and orbit information such as ephemeris (precise satellite orbit information) and almanac. The positioning calculation is performed on the assumption that a certain amount of error is included in the internal time of wearable device 200. That is, in addition to the x, y, and z parameters for specifying the three-dimensional position of wearable device 200, the time error is also an unknown. Therefore, wearable device 200 receives satellite signals (radio waves) transmitted from, for example, three or more GPS satellites, performs positioning calculation using GPS time information and orbit information included therein, and Position information can be acquired.

  As shown in FIG. 5, when the user is moving uphill (uphill slope) after starting workout, the control unit 90 displays a display mode (upstream movement display) related to uphill movement. Then, when the user's movement is changed from the upward movement to the state where the user is moving on the flat ground, the control unit 90 switches the display mode to the flat movement display mode (flat movement display), and further displays from the flat movement. When it changes to the state which is moving on the downhill (downhill slope), it controls to switch to the display mode (display OFF) concerning the downward movement, and instructs the display unit 50. Thereafter, the control unit 90 can similarly control the display until the end of the workout.

  The display control method of this example is a display control method for controlling the display of the display unit 50 according to the movement state of the user, and is based on the atmospheric pressure data acquired by the pressure sensor 57 that measures the atmospheric pressure in the movement path of the user. Depending on whether or not the gradient is within a threshold value, step S109 for determining whether or not the user is moving downward, and if it is determined that the user is moving downward, stop updating the display on the display unit, or Erasing step S115.

  As shown in FIG. 6, first, the control unit 90 measures the atmospheric pressure data related to the point before the user's movement by the pressure sensor 57 (step S101), and stores the first atmospheric pressure data as the initial atmospheric pressure data. Record 180. In addition, the control unit 90 measures the position data before the user's movement by the satellite positioning unit 160 or the acceleration sensor 55 (step S102), and records it in the storage unit 180 as initial position data. Next, the control unit 90 measures the atmospheric pressure data at the point (current location) where the user has moved (step S103), and records the second atmospheric pressure data as the atmospheric pressure data of the current value at the user's moving point in the storage unit 180. . Further, the control unit 90 measures the current position data of the point (current location) where the user has moved by the satellite positioning unit 160 or the acceleration sensor 55 (step S104), and records the current position data in the storage unit 180 as the current position data.

  Next, the control unit 90 receives the position information including the initial position data and the current position data acquired by the satellite positioning unit 160 or the acceleration sensor 55 from the storage unit 180, the first atmospheric pressure data, and the second atmospheric pressure data. Reading, obtaining the user's moving distance from the initial position data and current position data, and obtaining the altitude difference in the user's moving distance from the first atmospheric pressure data (initial value of atmospheric pressure) and the second atmospheric pressure data (current value of atmospheric pressure). . And the control part 90 calculates the gradient (inclination) of the area which the user moved based on a user's moving distance and the height difference in a moving distance (step S105). Then, the control unit 90 compares the calculated gradient with a preset threshold value (step S107), and determines whether or not the change amount of the gradient is within the threshold value (step S109). Note that the first atmospheric pressure data and the second atmospheric pressure data are not necessarily recorded in the storage unit 180, and the gradient (inclination) of the section in which the user has moved is calculated using the measured atmospheric pressure data as it is. Good.

  The control unit 90 controls the display of the display unit 50 based on the magnitude of the gradient, and when it is determined in step S109 that the gradient is within the threshold (Yes in step S109), the control unit 90 determines that the movement is flat and the display unit 50 is flat. Display of information related to movement, for example, display of information in the display mode illustrated in FIGS. 8 and 9 is instructed (step S113) and displayed. Note that the comparison with the threshold value in step S107 may be performed using a change amount of the slope instead of the slope.

  In the display example 2 shown in FIG. 8, the accumulated distance, split time, and pace of the flat movement section are displayed on the display unit 50 of the device main body 18. Note that the pace indicates the time taken per unit distance. The split time indicates the time taken for the flat movement section. In the display example 3 shown in FIG. 9, the accumulated distance of the flat movement section, the pulse rate (heart rate) and the heart rate zone of the flat movement section are displayed on the display unit 50 of the device main body 18.

  The information relating to the flat movement is preferably at least one of a pulse rate, a heart rate, a heart rate zone, a moving speed, and a moving distance. By displaying such information, the user can easily obtain detailed information such as the state of the body (physical condition) and movement status related to flat movement by visually recognizing the display.

  Further, when it is determined in step S109 that the gradient is not within the threshold value, that is, exceeds the threshold value (step S109: No), the control unit 90 determines whether the gradient is negative (−) (step S109). S111), when the gradient is minus (−) (step S111: Yes), it is determined that the movement is a downward movement, and the display update of the display unit 50 is stopped, the display update frequency of the display unit 50 is decreased, or As shown in FIG. 7, the display on the display unit 50 is turned off (turned off) (step S115).

  In addition, when the gradient is not minus (−), that is, plus (+) in the determination in step S111 (step S111: No), the control unit 90 determines that the movement is an upward movement and moves to the display unit 50. For example, the display of information according to the display mode, for example, the display of information in the display mode illustrated in FIGS. 10 and 11 is instructed and displayed (step S117).

  In the display example 4 shown in FIG. 10, the accumulated distance, the pulse rate (maximum value, minimum value, average value, etc.) of the upward movement section, and the gradient of the upstream section are displayed on the display unit 50 of the device body 18. The Further, in the display example 5 shown in FIG. 11, the number of steps up in the building, the split time, and the heart rate zone are displayed on the display unit 50 of the device main body 18.

  In addition, information related to upward movement includes the pulse rate, heart rate, heart rate zone, moving speed, moving distance, accumulated value of the number of steps of the moved staircase, accumulated value of the actually moved floor number, or virtually moved floor. It is preferably at least one of the numbers. By displaying such information, the user can easily obtain it by visually recognizing the display of detailed information such as the state of the body (physical condition) related to the upward movement and the movement status. Here, the information related to uphill movement is not limited to outdoor competitions such as trail run races, but it is also possible to obtain information such as the number of moving floors and steps up and down in the building, so how much in daily life You can see if you have exercised. Note that the cumulative value of the number of virtual floors may be a quotient obtained by dividing the cumulative value of the altitude change accompanying the movement of the user by the height of one floor, for example, 3 meters, or the altitude change is 3 It may be calculated by increasing the number of floors by one each time the meter is reached.

  Note that the threshold value used in the determination in step S107 can be set in advance by the user, and the display content desired by the user can be accurately displayed in each movement state.

  Thereafter, the control unit 90 determines whether or not there is an instruction to end measurement, that is, a workout end from the user (step S119), and when there is an instruction to end measurement (step S119: Yes), the series of procedures is ended. To do. If there is no instruction to end measurement (step S119: No), the control unit 90 returns to step S101 and continues display control according to a series of flows.

  According to the display control method described above, when it is determined that the movement state of the user is a downward movement based on the atmospheric pressure data in the movement path of the user measured by the pressure sensor 57, the update of the previous display is stopped, or Control is performed so that the display on the display unit 50 is turned off. In other words, in this mode, the power that has been wasted due to the display being performed or the display being updated, even in the case of a downward movement in which the user rarely runs while looking at the display screen, is displayed in the downward movement in this aspect. The power consumption can be reduced because the display is turned off or the display update is stopped. As described above, since the speed is easily increased, it is possible to reduce the power consumption related to the display at the time of the downward movement that is less likely to run while looking at the screen.

  Note that if the controller 90 determines that the gradient has fallen within the threshold and the downlink movement has ended from the state of the downlink movement, the control unit 90 determines that the display of the display by the user has become possible, and the performance information of the section related to the downlink movement Is preferably displayed. Here, when it is determined that the downlink movement has ended, the case where the downlink movement state has ended and the user has stopped, or the case where it has been determined that the downlink movement state has shifted to a flat movement or an uplink movement state. In other words.

  As described above, when it is determined that the state has shifted from the down movement state to the flat movement or the up movement state, it is determined that the display can be visually recognized by the user, similarly to the case where it is determined that the down movement has ended. The performance information of the section related to the downlink movement (hereinafter referred to as “downlink section”) can be displayed. In this way, it is necessary to increase the motivation of the user while suppressing the power consumption by displaying the performance information of the downlink section in the state where the downlink movement is finished and the user can visually recognize the display. Information can be output. Here, the performance information can indicate an average moving speed, a maximum moving speed, a gradient, a height difference, the number of steps, a descent rate per step, and the like.

  The control unit 90 preferably displays a reward screen if there is personal best information, for example, personal best record update information, in the performance information described above. The reward screen here may include, for example, displays such as “best record update”, “target achievement”, “GOOD”, “VERY GOOD”, and the like. When such a display is performed and a user in a stable moving state visually recognizes, the user's motivation can be further improved.

  According to the wearable device 200 described above, when the control unit 90 that controls the display determines that the movement state of the user is a downward movement based on the atmospheric pressure data measured by the pressure sensor 57 in the movement path of the user, Turn off the display (display OFF), stop the display update, or lower the display update frequency. In other words, conventionally, the user has not only run while looking at the screen, but also controls the display during dangerous down movement, that is, in this mode, the display update is stopped or the display update frequency is reduced during down movement. Alternatively, power consumption can be reduced by stopping the power supply to the display unit 50 and turning off the display. At the same time, it is possible to make it a habit for users not to see the display when moving down, so it can not only improve safety in moving down, but also contribute to improving performance because it can concentrate on walking. .

  Also, according to the wearable device 200, the display is automatically switched depending on the movement state. For example, when moving up, a display mode (uphill movement display) related to the uphill movement is displayed and moving on a flat ground. When the state is changed, the display mode (flat movement display) related to the flat movement is automatically displayed. This eliminates the need for a display switching operation and allows the user to concentrate on the race. In other words, it is possible to suppress distraction of the user's attention. Furthermore, information useful to the user can be accurately provided according to the situation. In addition, since the display is automatically switched, it is particularly effective in a sport where it is difficult to manually switch the display due to the fact that both hands are blocked, such as mountain bikes and bicycle races, and the user can easily obtain information. Can do.

(Modification of display control method)
<Modification 1>
Next, Modification 1 of the display control method by the control unit 90 of the wearable device 200 will be described with reference to FIGS. 12 and 13. FIG. 12 is a flowchart illustrating a first modification of the display control method according to the movement state of the user. FIG. 13 is a plan view showing a display example 6 displayed according to the movement state of the user.

  In the first modification of the display control method described here, it is determined whether or not the user's visual operation is performed based on the detection data of the acceleration sensor 55 as in the above-described embodiment, and depending on the determination result. The display on the display unit 50 is switched. That is, when it is determined that the user's visual operation is being performed, the performance information of the section of the downward movement is displayed. That is, when it is determined that the user is performing a visual operation by the operation of the wrist of the user to which the wearable device 200 is attached, the performance information of the downward movement section is displayed. It should be noted that the performance information of the downward movement section can be displayed when the determination of the end of the downward movement due to the change of the gradient and the determination that the user is performing the visual movement are made. Hereinafter, Modification Example 1 of the display control method will be described, but description of steps similar to those in the above-described embodiment will be omitted. The configuration of wearable device 200 will be described using the same configuration names and symbols as described above.

  The display control method of the first modification is a display control method for controlling the display of the display unit 50 according to the movement state of the user, and is based on the atmospheric pressure data acquired by the pressure sensor 57 that measures the atmospheric pressure in the movement path of the user. Based on whether or not the gradient is within the threshold value, step S109 for determining whether or not the user is moving downward, and when it is determined that the user is moving downward, updating the display on the display unit 50 is stopped. Step S115 for reducing the display update frequency of the display unit 50 or turning off the display of the display unit 50, and Steps S121 and S131 for determining whether or not the user's visual operation has been performed based on the detection data of the acceleration sensor 55. If it is determined in step S121 or step S131 that the user's visual operation has been performed, Step S123 of displaying a scan information, including a step S133, the.

  First, similarly to the step described above with reference to FIG. 6, the control unit 90 measures the atmospheric pressure data related to the point before the user's movement by the pressure sensor 57 from step S101 to step S103, step S105, step S107, step. S109 and step S111 for determining whether or not the gradient is minus (−) are sequentially practiced.

  Similar to the above-described embodiment, the control unit 90 determines that the movement is flat when the gradient is determined to be within the threshold value in step S109 (step S109: Yes). Then, the control unit 90 determines whether or not the visual operation of display by the user has been performed (step S131), moves the wrist to which the wearable device 200 is attached so that the user performs the visual operation, and the acceleration sensor 55. When it is determined that the visual motion is detected (step S131: Yes), the performance information of the downstream section is displayed in the display mode as shown in the display example 6 of FIG. 13 (step S133).

  In the display example 6 shown in FIG. 13, the accumulated distance of the down movement section, the average moving speed, and the gradient of the down section are displayed on the display unit 50 of the device body 18 as an example of the performance information of the down section. . Note that the performance information in the downlink section is information including an average moving speed, a maximum moving speed, an inclination, a height difference, the number of steps, a decrease rate per step, and the like of the user in the downlink section.

  After displaying the performance information of the downlink section, the control unit 90 determines whether or not a predetermined time for displaying the performance information of the downlink section has elapsed (step S135). When determining that the predetermined time has elapsed in step S135 (step S135: Yes), the control unit 90 switches the display of the display unit 50 and displays information related to the flat movement (step S113). In addition, when it is determined that the predetermined time has not elapsed in Step S135 (Step S135: No), the control unit 90 continues to display the performance information of the downstream section. The predetermined time used in the determination in step S135 can be set in advance by the user.

  If it is determined in step S109 that the gradient is not within the threshold value (step S109: No), the control unit 90 proceeds to step S111 where it is determined whether or not the gradient is negative (−). And similarly to the above-mentioned form, when the gradient is minus (−) in Step S111 (Step S111: Yes), the control unit 90 determines that the movement is a downward movement and stops updating the display of the display unit 50. Or turn off the display on the display unit 50 (step S115).

  Then, when the control unit 90 determines in step S111 that the gradient is not minus (−), that is, the downward movement is finished or is not in the downward movement state (step S111: No), the next procedure is performed. Then, it is determined whether or not the display visual operation by the user has been performed (step S121).

  When determining that the gradient is minus (−) in the determination in step S111 (step S111: Yes), the control unit 90 determines that the movement is a downward movement, and stops updating the display on the display unit 50. The display update frequency of the unit 50 is decreased or the display of the display unit 50 is turned off (turned off) (step S115).

  In addition, the control unit 90 moves the wrist on which the wearable device 200 is attached so that the user performs a visual operation of the display in step S121, that is, the user performs the visual operation, and the acceleration sensor 55 detects the visual operation. If it is determined that it has been performed (step S121: Yes), the performance information of the downstream section is displayed in the display mode as shown in display example 6 of FIG. 13 (step S123).

  As described above, when the control unit 90 determines that the downward movement is finished (step S111: No), and then determines that the user's visual operation is performed on the detection data of the acceleration sensor 55 (step S121: Yes), The performance information of the downlink section is displayed (step S123). Therefore, it is possible to display the performance information of the down section and make it visible to the user when it detects that the user himself can see the display after detecting that the down movement has ended Become.

  In addition, the control unit 90 determines in step S121 that the visual operation of the display by the user is not performed, that is, the user does not move the wrist to which the wearable device 200 is attached so as to perform the visual operation (step S121). : No), the display unit 50 is instructed to display information related to uplink movement, for example, display of information in the same display mode as exemplified in FIGS. 10 and 11 (step S127).

  After displaying the performance information of the downlink section in step S123, the control unit 90 determines whether or not a predetermined time for displaying the performance information of the downlink section has elapsed (step S125). When the control unit 90 determines that the predetermined time has passed in step S125 (step S125: Yes), the control unit 90 switches the display of the display unit 50, and displays information related to the upward movement, for example, illustrated in FIGS. 10 and 11. The display of the information in the same display mode is instructed and displayed (step S127). If it is determined that the predetermined time has not elapsed in step S125 (step S125: No), the control unit 90 continues to display the performance information of the downstream section. Note that the predetermined time used in the determination in step S125 can be set in advance by the user.

  Thereafter, the control unit 90 determines whether or not there is an instruction to end measurement, that is, a workout end from the user (step S119), and when there is an instruction to end measurement (step S119: Yes), the series of procedures is ended. To do. If there is no instruction to end measurement (step S119: No), the control unit 90 returns to step S101 and continues display control according to a series of flows.

  According to the display control method according to the modified example 1 described above, when an operation that is caused by determining that the user can see the display is detected, the performance information of the downlink section performed the previous time is displayed. The user can view it. Therefore, the user can visually recognize the display in a situation where stable movement is possible, that is, a safer situation.

<Modification 2>
Next, a second modification of the display control method by the control unit 90 of the wearable device 200 will be described with reference to FIG. FIG. 14 is a flowchart showing a second modification of the display control method according to the movement state of the user.

The update frequency is lowered or the display on the display unit 50 is turned off (turned off) (step S115). If it is determined that the predetermined time has not elapsed in step S145 (step S145: No), the control unit 90 continues to display the performance information of the downstream section. The predetermined time used in the determination in step S145 can be set in advance by the user.

  In addition, when the gradient is not minus (−), that is, plus (+) in the determination of step S111 (step S111: No), the control unit 90 determines that the movement is an upward movement and moves to the display unit 50. For example, the display of information according to the display mode, for example, the display of information in the display mode illustrated in FIGS. 10 and 11 is instructed and displayed (step S117).

  After step S113, step S115, and step S117, the control unit 90 determines whether or not there is an instruction to end measurement, that is, a workout end from the user (step S119), and when there is an instruction to end measurement (step S119: Yes), a series of procedures is terminated. If there is no instruction to end measurement (step S119: No), the control unit 90 returns to step S107 and continues display control according to a series of flows.

  According to the display control method according to the modified example 2 described above, when the user wants to see the screen and performs a visual operation such as moving his arm, the performance information of the descending section performed last time is displayed. It becomes possible for the user to visually recognize and usability can be improved. The displayed performance information of the down section includes a pulse rate, a pulse zone, a descending speed, and the like.
