[0004] However, in the system disclosed in Patent Document 1, advice information is notified to the user based on exercise information acquired by a sensor while the user is exercising, so the advice information is notified frequently while the user is exercising, and the user needs to constantly concentrate while exercising. This poses a problem in that the user cannot efficiently acquire advice information, making it difficult for them to exercise in a relaxed manner.

[0005] The present invention has been made in view of the above problems, and has an object to provide a device that can efficiently acquire advice information. [Means for solving the problem]

[0006] In order to solve the above problem, the information providing device of the present invention comprises an acquisition means for acquiring an index value related to the user's body movements based on the body movements during exercise, and an output control means for causing an output unit to output advice for the user's exercise based on the index value, wherein the output control means alternately sets a first interval and a second interval as time intervals while the exercise is being performed, causes the output unit to output the advice during at least a portion of the first interval, and controls the output unit not to output the advice during at least a portion of the second interval. [Effects of the Invention]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] As shown in FIG. 1, the advice providing system 1 includes a motion sensor device 10 as an information providing device, and a wireless earphone 20.

[0011] The motion sensor device 10 is a wearable terminal device that is worn on the user's body (for example, around the waist) during exercise (for example, running). The wireless earphones 20 are audio output devices that are worn on the user's ears during exercise (for example, running), similar to the motion sensor device 10. The wireless earphones 20 are connected to the motion sensor device 10 for communication, for example, wirelessly.

[0012] 2, the motion sensor device 10 includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a storage unit 13, a display unit 14, an operation unit 15, a sensor unit 16, a sound output unit 17, and a communication unit 18. The components of the motion sensor device 10 are connected via a bus 19.

[0013] The CPU (acquisition means, output control means) 11 controls each component of the motion sensor device 10. The CPU 11 reads out a designated program from among the system programs and application programs stored in the storage unit 13, expands it in the RAM 12, and executes various processes in cooperation with the program. The CPU 11 also includes a clock circuit (not shown) and acquires the current time measured by the clock circuit. The RAM 12 is a volatile memory that forms a work area for temporarily storing various data and programs. The storage unit 13 is composed of a flash memory, an EEPROM (Electrically Erasable Programmable ROM), etc. The storage unit 13 stores the system programs and application programs executed by the CPU 11, as well as data required to execute these programs. Examples of data required to execute these programs include a voice database 131 and measurement data 132. The voice database 131 stores voice data of advice and cheering messages used to provide advice to a user about their exercise (e.g., running). The measurement data 132 stores index values ​​relating to various indices that indicate the movement of the user's body while exercising. These index values ​​are sequentially derived by the CPU 11 based on the measurement results measured by the sensor unit 16 while the user is exercising, and are stored in the measurement data 132. The various indices include, for example, pace, time, running time, pitch, stride, stride-to-height ratio, backward inclination of the trunk, vertical movement, vertical movement-to-height ratio, lower back sinking, left / right tilt of the pelvis, pelvic lift, pelvic rotation, pelvic rotation timing, left / right impact, kick-off time, ground contact time, ground contact time rate, landing impact, kick-off acceleration, deceleration amount, stiffness, and the like.

[0014] The display unit 14 is made up of multiple LED lamps and is capable of displaying the power ON / OFF state, data acquisition state (e.g., whether data is being acquired or not), data transmission state (e.g., whether data is being transmitted or not), the GPS receiver ON / OFF state, etc. The operation unit 15 is equipped with a power button (not shown) for switching the power ON / OFF, a start / end button (not shown) for instructing the start / end of exercise, etc., and the CPU 11 controls each unit based on instructions from this operation unit 15.

[0015] The sensor unit 16 includes an acceleration sensor, an angular velocity sensor, a GPS receiver, etc., and outputs the measurement results to the CPU 11. The sensor unit 16 may further include sensors other than those described above. The sound output unit 17 includes a DA converter, an amplifier, a speaker, etc. When outputting sound, the sound output unit 17 converts sound data into analog audio data and outputs it from the speaker. The communication unit 18 is, for example, a communication unit that employs a wireless standard such as Bluetooth (registered trademark), or a wired communication unit such as a USB terminal.

[0016] 3, the wireless earphone 20 includes a CPU 21, a RAM 22, a storage unit 23, a display unit 24, an operation unit 25, a sound output unit 26, and a communication unit 27. The various units of the wireless earphone 20 are connected via a bus 28.

[0017] The CPU 21 controls each component of the wireless earphones 20. The CPU 21 reads out a specified program from among the system programs and application programs stored in the storage unit 23, expands it in the RAM 22, and executes various processes in cooperation with the program. The RAM 22 is a volatile memory that forms a work area for temporarily storing various data and programs. The storage unit 23 is configured, for example, with a flash memory, an EEPROM, etc. The storage unit 23 stores the system programs and application programs executed by the CPU 21, as well as data necessary for executing these programs.

[0018] The display unit 24 is composed of multiple LED lamps and is capable of displaying the ON / OFF state of the power supply, the remaining battery level, etc. The operation unit 25 includes a power button (not shown) for switching the power supply ON / OFF, an adjustment button (not shown) for adjusting the level of sound output from the sound output unit 26, etc., and the CPU 21 controls each unit based on instructions from the operation unit 25. The sound output unit (output unit) 26 is composed of a DA converter, an amplifier, a speaker, etc. When outputting sound, the sound output unit 26 converts sound data into analog audio data and outputs it from the speaker. The communication unit 27 is a communication unit that employs a wireless standard such as Bluetooth (registered trademark).

[0019] Next, the operation of the advice providing system 1 will be described. Specifically, the advice providing process executed by the CPU 11 of the motion sensor device 10 will be described. This advice providing process is triggered when the user operates the start / end button (operation unit 15) to instruct the start of running. The advice providing process is terminated when the user operates the start / end button (operation unit 15) to instruct the end of running at a desired timing during the execution of the advice providing process (for example, when 60 minutes have passed since the start of running). In addition, when the advice providing process is executed, five indicators that the user wants to improve (for example, stride, landing impact, vertical movement, pelvic tilt, and trunk backward tilt) are set in advance. Furthermore, these indicators are prioritized in the following order: stride, landing impact, vertical movement, pelvic tilt, and trunk backward tilt. That is, stride is ranked first, landing impact is ranked second, vertical movement is ranked third, pelvic tilt is ranked fourth, and trunk backward tilt is ranked fifth. In the following description, it is assumed that the advice providing process is executed for the first time based on the above settings. In the advice providing system 1, advice on exercise based on the measurement results by the sensor unit 16 of the motion sensor device 10 (audio data corresponding to the advice) is transmitted to the wireless earphone 20 via the communication unit 18. In the following description, it is assumed that the wireless earphone 20 notifies the user of the content of the advice by outputting the advice received by the communication unit 27 from the sound output unit 26. In this case, the communication unit 18 of the motion sensor device 10 corresponds to the output unit.

[0020] 4, when the advice providing process is started, first, the CPU 11 of the motion sensor device 10 moves to an advice section (first section) where advice on running (exercise) is provided to the user (step S1). Next, the CPU 11 executes advice section processing (step S2).

[0021] As shown in FIG. 5, when the advice section processing starts, first, the CPU 11 determines whether the advice section transitioned to in step S1 of the advice providing processing (see FIG. 4) is the first advice section (advice section 1; see FIG. 7) (step S21). If it is determined in step S21 that the advice section is the first advice section (step S21; YES), the CPU 11 acquires an index value related to the first index from the measurement data 132 stored in the storage unit 13 (step S22). Here, the first index is assumed to be an index related to "stride," which has the highest priority preset by the user. Furthermore, acquisition of the index value related to the first index in step S22 is assumed to be performed, for example, every time the user advances 50 m after transitioning to the advice section. In other words, in one acquisition process in step S22, an index value related to the first index derived while the user advances 50 m is acquired.

[0022] Next, the CPU 11 acquires, from the voice database 131 (see FIG. 2), voice data relating to advice corresponding to the index value relating to the first index (stride) acquired in step S22 (step S23). For example, if the index value relating to the first index (stride) is an index value corresponding to a passing grade, voice data relating to advice such as "Your stride has increased, allowing you to run powerfully" is acquired from the voice database 131. On the other hand, if the index value relating to the first index (stride) is an index value that does not reach the passing grade, voice data relating to advice such as "Increase your stride a little more" is acquired from the voice database 131. Next, the CPU 11 causes the sound output unit 26 of the wireless earphone 20 to output corresponding advice (voice) based on the voice data acquired in step S23 (step S24).

[0023] Next, CPU 11 determines whether a predetermined time (10 minutes) has elapsed since transition to the advice section (step S25). If it is determined in step S25 that the predetermined time (10 minutes) has elapsed since transition to the advice section (step S25; YES), CPU 11 returns the process to the advice providing process (see FIG. 4) and executes the processes from step S3 onwards. If it is determined in step S25 that the predetermined time (10 minutes) has not elapsed since transition to the advice section (step S25; NO), CPU 11 returns the process to step S21 and executes the processes from step S21 onwards.

[0024] Furthermore, if it is determined in step S21 that the advice section is not the first advice section (step S21; NO), that is, if it is determined that the advice section is advice section 2 or advice section 3 shown in FIG. 7, the CPU 11 determines whether the advice target index of the immediately preceding advice section was the first index (stride) (step S26). If it is determined in step S26 that the advice target index of the immediately preceding advice section was the first index (stride) (step S26; YES), the CPU 11 determines whether the improvement degree of the first index (stride) of the immediately preceding advice section was 70% or more (step S27). Here, if an index value related to the first index (stride) derived in the immediately preceding advice section that corresponds to a passing grade is obtained for a period of 7 minutes or more out of the 10 minutes of the advice section, it is determined that the improvement degree of the first index (stride) of the immediately preceding advice section was 70% or more. Note that an index value that corresponds to a passing grade means that a certain index value is larger (or smaller) than a threshold value set for each certain index value. In other words, an index value equivalent to a passing grade is a state in which a certain index value is superior to a threshold value. For example, if the index value of stride is greater than the threshold value, the index value is equivalent to a passing grade, and if the index value of vertical fluctuation is smaller than the threshold value, the index value is equivalent to a passing grade. Therefore, "the improvement rate of the first index is 70% or more" indicates that the index value of the first index is judged to be good relative to the predetermined threshold value for a predetermined percentage of a predetermined period. Therefore, if the index value of the first index (stride) derived in the immediately preceding advice section is not equivalent to a passing grade for a period of 7 minutes or more out of the 10-minute advice section, the improvement rate of the first index (stride) in the immediately preceding advice section is judged to be less than 70%. Note that in the time chart shown in FIG. 7, a circle following the word "improvement rate" indicates that the improvement rate is 70% or more. On the other hand, a cross following the word "improvement rate" indicates that the improvement rate is less than 70%.

[0025] If it is determined in step S27 that the degree of improvement in the first index (stride) in the immediately preceding advice section (e.g., advice section 1 in cases 1 to 4; see FIG. 7) is not 70% or more (step S27; NO), the CPU 11 transitions the process to step S22 and repeatedly executes the processes from step S22 onward. If it is determined in step S27 that the degree of improvement in the first index (stride) in the immediately preceding advice section (e.g., advice section 1 in cases 5 to 6; see FIG. 7) is 70% or more (step S27; YES), the CPU 11 acquires an index value related to the second index from the measurement data 132 stored in the storage unit 13 (step S28). Here, the second index is assumed to be an index related to "landing impact," which has the second highest priority set by the user. The acquisition of the index value related to the second index in step S28 is performed, for example, every 50 m after the user moves forward, similar to the acquisition of the index value related to the first index in step S22. That is, in one acquisition process in step S28, an index value related to the second index derived while the user moves forward 50 m is acquired. After executing the process of step S28, CPU 11 shifts the process to step S23 and repeatedly executes the processes from step S23 onwards.

[0026] Furthermore, in step S26, if it is determined that the advice target index of the immediately preceding advice section (for example, advice section 2 in Cases 5 to 6; see FIG. 7) is not the first index (stride) (step S26; NO), that is, if the advice target index of the immediately preceding advice section is the second index (landing impact), the CPU 11 determines whether the degree of improvement of the second index (landing impact) of the immediately preceding advice section was 70% or more (step S29). Here, if an index value related to the second index (landing impact) derived in the immediately preceding advice section and corresponding to a passing grade is obtained for a period of 7 minutes or more out of the 10 minutes of the advice section, it is determined that the degree of improvement of the second index (landing impact) of the immediately preceding advice section was 70% or more. Therefore, if the index value for the second index (landing impact) derived in the immediately preceding advice section is not obtained at least for 7 minutes out of the 10 minutes of the advice section, it will be determined that the improvement in the second index (landing impact) in the immediately preceding advice section is not 70% or more.

[0027] If it is determined in step S29 that the degree of improvement in the second index (landing impact) in the immediately preceding advice section (e.g., advice section 2 in case 6; see FIG. 7) is not 70% or more (step S29; NO), the CPU 11 shifts the process to step S28 and repeatedly executes the processes from step S28 onwards. Also, if it is determined in step S29 that the degree of improvement in the second index (landing impact) in the immediately preceding advice section (e.g., advice section 2 in case 5; see FIG. 7) is 70% or more (step S29; YES), the CPU 11 acquires voice data relating to a cheering message (e.g., "Do your best in the remaining 1 km!") from the voice database 131 (see FIG. 2) (step S30). Then, the CPU 11 shifts the process to step S24 and repeatedly executes the processes from step S24 onwards.

[0028] 4, when the advice section process in step S2 ends, the CPU 11 moves to a refresh section (second section) (step S3) Next, the CPU 11 executes a refresh section process (step S4).

[0029] 6, when the refresh interval process starts, first, the CPU 11 determines whether or not the advice target index of the immediately preceding advice interval was the second index (landing impact) (step S41). If it is determined in step S41 that the advice target index of the immediately preceding advice interval (for example, advice interval 2 in cases 1 to 4; see FIG. 7) is not the second index (landing impact) (step S41; NO), that is, if the advice target index of the immediately preceding advice interval is the first index (stride), the CPU 11 skips steps S42 to S46 and proceeds to the process at step S47. Furthermore, in step S41, if it is determined that the advice target indicator for the immediately preceding advice section (for example, advice section 2 of cases 5 to 6; see Figure 7) is the second indicator (landing impact) (step S41; YES), the CPU 11 determines whether the improvement in the first indicator (stride) for the immediately preceding advice section (for example, advice section 2 of cases 5 to 6; see Figure 7) was 70% or more (step S42).

[0030] If it is determined in step S42 that the degree of improvement in the first index (stride) in the immediately preceding advice section (e.g., advice section 2 in case 5; see FIG. 7) is 70% or more (step S42; YES), the CPU 11 skips steps S43 to S46 and proceeds to step S47. If it is determined in step S42 that the degree of improvement in the first index (stride) in the immediately preceding advice section (e.g., advice section 2 in case 6; see FIG. 7) is not 70% or more (step S42; NO), the CPU 11 acquires an index value related to the first index (stride) from the measurement data 132 stored in the storage unit 13 (step S43). The acquisition of the index value related to the first index in step S43 is performed, for example, every time the user advances 50 m after transitioning to the refresh section. That is, in one acquisition process in step S22, an index value related to the first index derived while the user advances 50 m is acquired.

[0031] Next, the CPU 11 acquires audio data related to advice corresponding to the index value related to the first index (stride) acquired in step S43 from the audio database 131 (see FIG. 2) (step S44). Subsequently, the CPU 11 causes the sound output unit 26 of the wireless earphone 20 to output corresponding advice (audio) based on the audio data acquired in step S44 (step S45). Note that audio data related to a cheering message may be acquired from the audio database 131 in step S44, and the cheering message (audio) may be output from the sound output unit 26 of the wireless earphone 20 following the advice (audio) in step S45.

[0032] Next, CPU 11 determines whether a first predetermined time (2 minutes (e.g., the first 2 minutes of refresh interval 2 in case 6; see FIG. 7)) has elapsed since the transition to the refresh interval (step S46). If it is determined in step S46 that the first predetermined time (2 minutes) has not elapsed since the transition to the refresh interval (step S46; NO), CPU 11 returns the process to step S43 and executes the subsequent processes. Also, if it is determined in step S46 that the first predetermined time (2 minutes) has elapsed since the transition to the refresh interval (step S46; YES), CPU 11 determines whether a second predetermined time (10 minutes) has elapsed since the transition to the refresh interval (step S47).

[0033] If it is determined in step S47 that the second predetermined time (10 minutes) has not elapsed since the transition to the refresh section (step S47; NO), the CPU 11 repeatedly executes the determination process of step S47 until the second predetermined time has elapsed. Furthermore, if it is determined in step S47 that the second predetermined time (10 minutes) has elapsed since the transition to the refresh section (step S47; YES), the CPU 11 returns the process to the advice providing process (see FIG. 4) and executes the processes from step S1 onward. Here, after the determination process of step S46, if it is determined in step S47 that the second predetermined time (10 minutes) has elapsed since the transition to the refresh section, the CPU 11 has controlled the sound output unit 26 of the wireless earphone 20 not to output advice during at least a part of the refresh section (second section) (for example, the latter 8 minutes of refresh section 2 in case 6; see FIG. 7).

[0034] Note that if the improvement in the first indicator (stride) is 70% or more in all advice intervals during one run, i.e., in the example of FIG. 7, in all advice intervals 1 to 3 (in other words, if the improvement in the first indicator is 70% or more consecutively in the three advice intervals 1 to 3. However, the improvement in the second indicator (landing impact) is not 70% or more consecutively in all advice intervals 1 to 3), then in the advice providing process for the next run, the first indicator to be advised will shift to "landing impact" and the second indicator to "vertical movement." Also, if the improvement in each of the first indicator (stride) and second indicator (landing impact) is 70% or more in all advice intervals 1 to 3, then in the advice providing process for the next run, the first indicator to be advised will shift to "vertical movement" and the second indicator to "lateral tilt of the pelvis."

[0035] As described above, the CPU 11 of the motion sensor device 10 of this embodiment acquires an index value related to the user's body movement based on the body movement (running form) while the user is running (exercising), and outputs advice for the user's exercise to the output unit (the sound output unit 26 of the wireless earphone 20) based on the index value. Furthermore, while the user is running, the CPU 11 sets advice intervals (first intervals) and refresh intervals (second intervals) that are time intervals (intervals having a predetermined time length) in an alternating manner, outputs advice to the sound output unit 26 of the wireless earphone 20 during at least part of the advice interval, and controls the sound output unit 26 of the wireless earphone 20 not to output advice during at least part of the refresh interval (for example, the last 8 minutes of refresh interval 2 in Case 6; see FIG. 7 ). Therefore, according to the motion sensor device 10, by setting advice intervals and refresh intervals in an alternating manner, the user can efficiently obtain advice information during the advice intervals and can perform relaxed exercise during the relax intervals.

[0036] Furthermore, the CPU 11 causes the sound output unit 26 of the wireless earphone 20 to output advice according to a first index value (index value related to the first index) designated in advance among the multiple types of index values ​​during the advice section, and if the first index value satisfies a predetermined condition during the advice section (if the improvement in the first index is 70% or more), causes the sound output unit 26 of the wireless earphone 20 to output advice according to a second index value (index value related to the second index) designated in advance among the multiple types of index values ​​during the next advice section (for example, advice section 2 in Cases 5 to 6; see FIG. 7). Therefore, according to the motion sensor device 10, by shifting the target of advice from the first index to the second index, it is possible to let the user know that the improvement in the first index has increased, thereby increasing the user's motivation to improve their running form.

[0037] Furthermore, if the first index value (index value related to the first index) does not satisfy a predetermined condition in an advice section (if the degree of improvement of the first index is less than 70%), the CPU 11 causes the sound output unit 26 of the wireless earphone 20 to output advice according to the first index value (index value related to the first index) in the next advice section (for example, advice section 2 in cases 1 to 4; see FIG. 7). Therefore, according to the motion sensor device 10, if the degree of improvement of the first index does not improve, advice targeted at the first index is output again, thereby encouraging improvement of the first index.

[0038] Furthermore, if the first index value (index value related to the first index) satisfies a predetermined condition (if the degree of improvement of the first index is less than 70%) in an advice section (e.g., advice section 2 in Case 6; see FIG. 7) in which advice related to the second index value (index value related to the second index) is output, the CPU 11 causes the sound output unit 26 of the wireless earphone 20 to output advice related to the first index value (index value related to the first index) in a predetermined length of time (first predetermined time; see FIG. 6) in a section other than at least a part of the refresh section set immediately after the advice section (e.g., the first two minutes of refresh section 2 in Case 6; see FIG. 7). Therefore, according to the motion sensor device 10, if the degree of improvement of the first index improves and then decreases, the motion sensor device 10 can follow up on the improvement of the first index by again outputting advice targeted at the first index using the predetermined length of time of the refresh section.

[0039] The description in the above embodiment is merely an example of the information providing device, the information providing method, and the program according to the present invention, and the present invention is not limited to this. For example, in the above embodiment, if it is determined in step S25 of the advice section processing (see FIG. 5) that a predetermined time (10 minutes) has elapsed since the transition to the advice section (step S25; YES), CPU 11 may derive an evaluation score for the advice target index (e.g., the first index (stride)) for the advice section, and output a sound notifying the derived evaluation score (e.g., "The evaluation score for stride is 75 points") from sound output unit 26 of wireless earphones 20. In this way, providing the user with feedback on the evaluation score derived in the advice section can lead to an improvement in running form in the next advice section and increase the user's motivation to further improve their running form.

[0040] In the above embodiment, the advice section and the refresh section are each described as having a duration of 10 minutes. However, the durations of the advice section and the refresh section may be different. The durations (lengths) of the advice section and the refresh section may be variably set depending on the user's running (exercise) situation and environment. Specifically, at the beginning of a run, the refresh section may be set to a duration longer than the usual 10 minutes (for example, 12 minutes), and the advice section may be set to a duration shorter than the usual 10 minutes (for example, 8 minutes). Then, when the improvement in the first indicator (for example, stride) reaches a predetermined percentage (for example, 50%), the durations of the subsequent advice sections may be gradually lengthened. When running a circular course or running in rainy weather, the advice section may be set to a duration longer than the usual 10 minutes (for example, 14 minutes) to help maintain motivation for running. Whether the user is running a circular course may be determined based on a movement trajectory, which is a positioning result obtained by a GPS receiver included in the sensor unit 16. When the CPU 11 determines that the user is running on a circular course, the CPU 11 may automatically adjust the length of the advice section. Whether or not it is raining may be determined using the detection results of the barometric pressure sensor or raindrop sensor provided in the sensor unit 16. This allows advice information to be acquired efficiently without requiring user operation. When running on a scenic course, the refresh section may be set to a time longer than the usual 10 minutes (for example, 14 minutes) to prioritize refreshing the user. When running in a relatively noisy area such as an urban area, the advice may be difficult to hear, so the advice section may be set to a time shorter than the usual 10 minutes (for example, 6 minutes). Whether the course is scenic or in the urban area may be determined by estimating the user's position on the map based on the positioning results of the GPS receiver and map data stored in the memory unit 13. The positions of the scenic course and the urban area may be set in advance in the memory unit 13. This allows advice information to be acquired efficiently without requiring user operation.Furthermore, when running during times when traffic volume is relatively low, such as early morning or night, advice tends to be easier to hear, so the advice section may be set to a length longer than the usual 10 minutes (for example, 12 minutes). Also, if the degree of improvement in the advice target index during the advice section is steadily increasing, the advice section thereafter may be gradually lengthened and the refresh section gradually shortened.

[0041] Furthermore, in the above embodiment, the advice target indicators in the advice providing process (see FIG. 4) are two, a first indicator (e.g., stride) and a second indicator (e.g., landing impact), but three or more types of indicators may be used as the advice target indicators. In such a case, for example, advice corresponding to each of two or more types of indicators may be output in one advice interval. Specifically, the maximum number of pieces of advice that can be output in subsequent advice intervals may be changed depending on the index value of the first indicator in the first advice interval. Furthermore, as described above, when the duration of the advice interval is variably set, the maximum number of pieces of advice that can be output in the advice interval may be changed depending on the length of the advice interval, for example, by increasing the maximum number of pieces of advice in longer advice intervals and decreasing the maximum number of pieces of advice in shorter advice intervals. Furthermore, the type and number of advice target indicators may be changed depending on the temporal position of the advice interval (e.g., advice interval 1, advice interval 2, advice interval 3; see FIG. 7). Specifically, in the first half of the advice interval, the advice target indicator may be changed to one with a higher level of difficulty, or the number of advice target indicators may be increased. In addition, in the latter advice section, the advice target index may be changed to one with a lower level of difficulty, or the types of advice target index may be reduced.

[0042] In the above embodiment, in case 6 of FIG. 7 , the index value is acquired and advice is output during the first predetermined time (2 minutes) in refresh interval 2. However, this is not limited to this. If the acquired index value is detected as being good a predetermined number of times in succession, the first predetermined time may be shortened. The first predetermined time may also be set according to the priority of the index for which advice is being provided. For example, the first predetermined time may be set to 3 minutes if the priority is first, 2 minutes 45 seconds if the priority is second, or 2 minutes 30 seconds if the priority is third. The first predetermined time may also be set according to the temporal position of the refresh interval. For example, the first predetermined time may be set to 3 minutes if the priority is first, 2 minutes 45 seconds if the priority is second, or 2 minutes 30 seconds if the priority is third.

[0043] Furthermore, the motion sensor device 10 may be any wearable terminal device that is worn on the user's body during exercise (for example, running), and may be, for example, a smartphone that is worn on the user's wrist, a smart watch that is worn on the user's wrist, etc. When the motion sensor device 10 is the above-mentioned smart watch, the sensor unit 16 may further include a heart rate sensor (pulse wave sensor).

[0044] In addition, in the above embodiment, in the advice providing process (see Figure 4), the advice is output from the sound output unit 26 of the wireless earphone 20, but the advice may also be output from the sound output unit 17 of the motion sensor device 10, for example.

[0045] Furthermore, although the advice providing system 1 in the above embodiment is configured from the motion sensor device 10 and the wireless earphones 20, this is not limiting. The detection results detected by the sensor unit 16 of the motion sensor device 10 may be received by a communication unit (not shown) included in the information processing device 30 (not shown). In this case, the information processing device 30 may output information related to advice corresponding to the received sensor detection results to the wireless earphones 20 via the communication unit of the information processing device 30. Therefore, according to the above configuration, it is sufficient that the control unit (not shown) included in the information processing device 30 executes the processes shown in the flowcharts of FIGS. 4 to 6. The information processing device 30 is, for example, a smartphone.

[0046] Furthermore, it goes without saying that the detailed configurations and operations of the components of the motion sensor device 10 and the wireless earphone 20 in the above-described embodiment can be modified as appropriate without departing from the spirit of the present invention.
