(Exercise support method)
Next, an exercise support method in the exercise support apparatus according to the present embodiment will be described. Here, an exercise support method when the user US performs running as an exercise operation will be described.

  FIG. 3 is a flowchart illustrating an example of an exercise support method in the exercise support apparatus according to the present embodiment. FIG. 4 is a flowchart illustrating an example of arm posture detection processing executed by the exercise support method according to the present embodiment. FIG. 5 is a signal waveform diagram showing an example of sensor data acquired by the exercise support method according to the present embodiment. FIG. 6 is a conceptual diagram showing an arm posture tracking operation (arm swing state detection operation) executed by the exercise support method according to the present embodiment. FIG. 7 is a flowchart illustrating an example of arm swing state determination / support processing executed by the exercise support method according to the present embodiment.

  In the exercise support method according to the present embodiment, as shown in FIG. 3, broadly divided into arm posture detection processing (step S100), arm swing evaluation processing (step S200), and arm swing state determination / support processing (step S300) are sequentially executed. Here, the arm swing state determination / support process (step S300) is the second and subsequent running operations after the arm posture detection process (step S100) and the arm swing evaluation process (step S200) are performed at least once. This is an exercise support operation that is sometimes performed, and is performed in a state where the arm swing angle data until the previous running operation and the evaluation information (label) given to the arm swing angle data are stored in the memory unit 160 It is.

(Arm posture detection processing)
In the arm posture detection process (step S100), first, the terminal 100 and the terminal 200 are activated by the user US operating the power switch of the terminal 100 and the terminal 200 worn on the body. Next, the user US operates the input operation unit 130 of the terminal 100 or the input operation unit 220 of the terminal 200 before or after the start of the running operation, so that the sensing operation in the terminal 100 is started, Various information providing operations in the terminal 200 are started.

  As a result, in the terminal 100 worn by the user US on the upper arm, as shown in the flowchart of FIG. 4, acceleration data during exercise is detected at any time by the acceleration sensor 110, and angular velocity data is detected at any time by the angular velocity sensor 120. Is done. The arithmetic circuit 150 stores these sensor data in association with time data in a predetermined storage area of the memory unit 160 (data memory) as needed (step S101).

  Here, the acceleration data acquired in step S101 is represented by a signal waveform diagram as shown in FIG. FIG. 5A shows a time change of the combined acceleration obtained by combining the acceleration data in the three-axis direction detected by the acceleration sensor 110 with the arithmetic circuit 150. Further, the angular velocity data acquired in step S101 is represented by a signal waveform diagram as shown in FIG. 5B, for example. FIG. 5B shows a temporal change in the combined angular velocity obtained by combining the angular velocity data in the three-axis directions detected by the angular velocity sensor 120 with the arithmetic circuit 150. As is apparent from the signal waveforms shown in FIGS. 5A and 5B, a maximum value and a minimum value appear in a substantially constant cycle in the signal waveform of the combined acceleration and the combined angular velocity applied to the human body during running. The appearance timings of these local maximum values and local minimum values have a close correspondence.

  Next, the arithmetic circuit 150 determines whether or not the user US is running based on the acquired acceleration data (step S102). Specifically, the determination is made based on whether the signal waveform of the resultant acceleration shown in FIG. 5A has a characteristic waveform during running. That is, it is known that a characteristic change having a specific period, intensity, etc. is observed in the signal waveform of the resultant acceleration during running. Therefore, it is possible to accurately determine whether or not the user US is running by observing the acceleration data in three axes and the signal waveform of the combined acceleration. In addition to the above-described method, the running discrimination process registers acceleration data when the user US has run in advance, and the registration data or the signal waveform thereof and the acceleration data acquired in step S101. May be discriminated by comparing.

  Next, when it is determined in step S102 that the user US is running (step S102; Yes), the arithmetic circuit 150 detects the landing timing in the running operation (step S103). Specifically, in the signal waveform of the resultant acceleration shown in FIG. 5A, the maximum value (indicated by a circle in the figure) is caused by an impact (landing impact) when the foot of the user US has landed. Since it can be regarded as a thing, the acceleration data detected at any time by the acceleration sensor 110 is tracked by the arithmetic circuit 150, and the timing indicating the maximum value is detected. Here, the detected landing timing is the start timing and the end timing of the operation period for one cycle in the arm posture tracking operation executed in step S107 described later. Further, the arithmetic circuit 150 detects the landing timing to acquire information on the number of steps and the pitch during running, and stores the information in a predetermined storage area of the memory unit 160 (data memory). Here, the number of steps is calculated by counting the number of landing impacts (landing timing), and the pitch is calculated by counting the number of steps per time.

  On the other hand, if it is not determined in step S102 that the user US is running (step S102; No), the observation of acceleration data and composite acceleration is continued. If the landing timing is not detected in step S103 (step S103; No), processing operations after step S107 described later are executed.

  Next, when the landing timing is detected in step S103 (step S103; Yes), the arithmetic circuit 150 calculates the arm swing angle in the tracking operation for one cycle, and calculates the arm swing angle data (arm swing). Angle data) is recorded (step S104). Specifically, in step S109, which will be described later, the arithmetic circuit 150 calculates the maximum value of the difference in the arm posture data from the plurality of arm posture data recorded during the tracking operation period for one cycle. The calculated arm swing angle data is stored in a predetermined storage area of the memory unit 160. The arm swing angle is calculated based on the distance from the shoulder joint (Na shown in FIG. 6) to the angular velocity sensor 120 provided on the terminal 100 and the value of the angular velocity ωt acquired based on the angular velocity data. . Here, the calculation process of the arm swing angle can be conceptually expressed as the following equation (1). That is, in the following equation (1), if the arm posture recorded in step S109, which will be described later, is Ak (k = 1 to n; n is a positive integer) and the calculated arm swing angle is Output, it is arbitrary. An angle angle (Ap, Aq), which is the difference between the direction angles defined by the arm positions in the two arm postures Ap and Aq (p, q = 1 to n), is calculated, and the maximum value ( max) is extracted as the arm swing angle. Expression (1) does not indicate a specific function expression for performing the arm swing angle calculation process, but merely indicates the concept of the process.

  Next, the step count, pitch, and arm swing angle values acquired based on the sensor data acquired at the terminal 100 are displayed as exercise motion information on the display unit 231 of the terminal 200 attached to the forearm (step S105). Specifically, the arithmetic circuit 150 of the terminal 100 extracts the number of steps and pitch calculated in step S103 and the arm swing angle calculated in step S104 from the memory unit 160 and passes through the communication circuit unit 170. Transmit to terminal 200. The arithmetic circuit 240 of the terminal 200 causes the display unit 231 to display exercise motion information including these data received via the communication circuit unit 210 in a predetermined display format.

  Here, in step S105, the value of the arm swing angle displayed as the exercise motion information on the display unit 231 of the terminal 200 is not the value acquired immediately before the display motion, but the arm executed in step S107 described later. In the posture tracking operation, a value acquired at least one cycle before the present time is set. In general, when the user US visually recognizes the display unit 231 of the terminal 200 attached to the forearm, the arm swinging operation is temporarily stopped, the arm swing is reduced, or With different major changes. Therefore, the value when the arm swing is insufficient under the influence is prevented from being displayed.

  Next, the arithmetic circuit 150 initializes tracking data in an arm posture tracking operation executed in step S107 described later (step S106). Specifically, the arithmetic circuit 150 detects the landing timing in step S103, thereby clearing (erasing) the arm posture data acquired by the tracking operation in the previous cycle and performing the tracking operation in the next cycle. The timing for starting is set in correspondence with the landing timing. Here, the start timing of the tracking operation in the next cycle corresponds to the end timing of the tracking operation in the previous cycle (that is, currently executed).

  Next, when the landing timing is not detected in step S103 (step S103; No), the arithmetic circuit 150 sequentially integrates the angular velocity data detected by the angular velocity sensor 120 with the above start timing as a base point. An operation for tracking (continuously tracking) the change in the arm posture is started (step S107). This tracking operation is executed in step S103 with a period from one landing timing until the next landing timing is detected, that is, a period of one step of the running operation as one cycle. Every time, tracking data (arm posture data) acquired in the previous cycle is initialized.

In step S107, specifically, information related to arm swing such as the position of the arm during the running operation and the direction of arm swing is acquired based on the signal waveform of the combined angular velocity shown in FIG. That is, by observing the angular velocity data in the three axis directions and the signal waveform of the combined angular velocity, it is possible to accurately grasp the state of the arm swing during the motion motion of the user US. Therefore, based on the integrated value of the three-axis direction angular velocity data detected by the angular velocity sensor 120 by the arithmetic circuit 150, the shoulder joint Na is used as a fulcrum as shown in FIGS. The position of the upper arm AMa and the direction of arm swing are tracked. Here, the angular velocity ωt at the time of arm swing is expressed by the following equation (2) when the angular velocity components in the three axial directions of x, y, and z that are orthogonal to each other are respectively ωx, ωy, and ωz.

  Then, the arithmetic circuit 150 detects the timing at which the angular velocity ω calculated at any time becomes the minimum value (step S108). Specifically, as shown in FIG. 6B, after the upper arm AMa swings to the maximum extent in one direction (for example, the DRa direction in the figure), the arm swing direction changes to the reverse direction (for example, the DRb direction in the figure). At the timing corresponding to the arm swing end, the angular velocity ω becomes a minimum value (≈0). Therefore, the arithmetic circuit 150 detects the timing at which the angular velocity shows a minimum value (indicated by a circle in the figure) in the composite angular velocity signal waveform shown in FIG.

  Next, when the minimum value of the angular velocity ω is detected in step S108 (step S108; Yes), the arithmetic circuit 150 sequentially records the arm posture at the timing (step S109). Specifically, when the arithmetic circuit 150 determines that the angular velocity ω is a minimum value, the arithmetic circuit 150 stores arm posture data including the arm position (direction angle) at the timing in a predetermined storage area of the memory unit 160. . The arithmetic circuit 150 repeatedly executes such processing in steps S108 and S109.

  Here, in steps S108 and S109, when the signal waveform of the composite angular velocity as shown in FIG. 5B is verified in detail, the angular velocity changes finely in the vicinity of the timing at which the angular velocity shows the minimum value. As shown in b), there may be local minimum values not only at the timing corresponding to the arm swing end when the arm swing direction of the user US changes, but also at a plurality of other timings. In such a case, in step S108, it is difficult to determine which local minimum value is caused by a change in arm swing direction (arm swing end) while the angular velocity continuously fluctuates. . Therefore, in the present embodiment, in step S109, arm postures at a plurality of timings (indicated by circles in FIG. 6B) at which the angular velocity has a minimum value are recorded.

  On the other hand, when the minimum value of the angular velocity ω is not detected in step S108 (step S108; No), the user US operates the input operation unit 130 of the terminal 100 or the input operation unit 220 of the terminal 200 to perform the sensing operation. Until the process is terminated or until the power is turned off, the process returns to step S101, and the above-described series of processing operations of steps S101 to S109 are repeatedly executed (step S110; No).

  The inventor of the present application conducted a verification experiment for such an arm posture detection process. The arm swing angle estimated from the running image of the user US and the above-described series of processing operations are attached to the upper arm. The correlation coefficient with the arm swing angle estimated based on the angular velocity data detected by the angular velocity sensor showed an extremely high value exceeding 0.95. Therefore, it has been found that the arm swing angle during running can be obtained with high accuracy by the method according to the present embodiment.

In the above-described arm posture detection process, the case where the timing at which the acceleration data shows the maximum value is set as the landing timing in step S103 has been described, but the present invention is not limited to this method. For example, when the signal waveform of acceleration as shown in FIG. 5A is verified in detail, the acceleration changes finely at timings other than the maximum value of acceleration caused by the landing of the foot, and the maximum is obtained at a plurality of timings. A value may exist. In such a case, for example, the maximum value and the acceleration value are equal to or greater than a predetermined threshold (for example, 40 m / s ² ), or the maximum value and the time change amount (time differential value) of the acceleration are equal to or greater than the predetermined value. The accurate landing timing can be detected by calculating or extracting the timing that satisfies the conditions.

  In step S104, the arm swing angle calculated by the arithmetic circuit 150 is the maximum value of the difference in arm posture data (arm direction angle) at each timing at which the angular velocity ω is minimized in steps S108 and S109. However, the present invention is not limited to this method. For example, the maximum value of the directional angle to the front of the arm (DRa direction shown in FIG. 6A) obtained by integrating the angular velocity data and the backward direction (DRb direction shown in FIG. 6B). An angle corresponding to the difference from the maximum value of the direction angle may be set as the arm swing angle.

  In step S105, when the user US visually recognizes the exercise motion information displayed on the display unit 231 of the terminal 200, the arm swing motion is temporarily stopped, the arm swing is reduced, or As a technique for avoiding the influence on the arm swing angle caused by different large changes, a technique for displaying a value acquired at least one cycle before the present time is shown. However, the present invention is limited to this technique. Is not to be done. For example, by incorporating an acceleration sensor in the terminal 200, the state of the arm when the user US is viewing the display unit is detected, and updating of the display is stopped only when the state is detected. Alternatively, a method of displaying a value acquired one cycle or more before may be applied. Specifically, during the running operation, the magnitude of the vertical acceleration becomes very large. On the other hand, when the user US performs an operation of visually recognizing the display unit 231 of the terminal 200, it is necessary to move the terminal 200 so that at least the forearm is lifted so that the display unit 231 can be visually recognized. Therefore, when the display unit 231 is visually recognized during the running operation, the acceleration in the direction perpendicular to the plane including the display unit 231 increases (operation condition 1). In addition, in this case, since the state where the arm is lifted is temporarily held, the change in the arm posture becomes small, and the magnitude of the angular velocity becomes small (operation condition 2). Therefore, when both states of the operating conditions 1 and 2 are detected at the same time, it is determined that the user US is viewing the display unit 231 of the terminal 200 during the running operation, and the arm swinging in the display unit 231 is performed. Stop updating the angle display.

  Moreover, in step S105 mentioned above, although the method of displaying on the display part 231 of the terminal 200 was demonstrated as a method of providing the user US with exercise | movement motion information containing an arm swing angle, this invention is limited to this. is not. That is, it is only necessary that the exercise motion information is appropriately provided to the user US. For example, in addition to the display on the display unit 231 described above or instead of the display on the display unit 231, the terminal 100 or the terminal 200 The motion operation information may be provided by voice information, alarm sound, or the like from the provided acoustic unit, or may be provided by vibration information from the vibration unit.

  Further, in step S107 described above, the case where the acceleration is set to the landing timing at which the maximum value is set as the timing (or the end timing) for starting the tracking operation of the arm posture change has been described, but the present invention is not limited to this. Is not to be done. That is, it is only necessary that the operation period for one cycle of the tracking operation is a period corresponding to one cycle of the arm swinging operation, for example, any arbitrary time that has deviated (elapsed) from the landing timing by a certain time. The timing may be set to the start timing and end timing of the tracking operation.

(Arm swing evaluation process)
In the arm swing evaluation process (step S200), the arm swing angle obtained by the arm posture detection process described above during the motion and stored in the memory unit 160 of the terminal 100 is displayed on the terminal 200 after the running motion ends. Displayed on the display unit 140 of the terminal 231 or the terminal 100. Here, as for the arm swing angle displayed on the display unit 231 or the display unit 140, the arm swing angle in each cycle acquired by the above-described arm posture detection process is displayed in a list format or a graph format.

  Next, the user US browses the arm swing angle displayed on the display unit 231 or the display unit 140, and subjective evaluation information (label) such as the condition of the running motion, for example, with respect to the arm swing angle. ). Then, the arithmetic circuit 150 of the terminal 100 stores the evaluation information in a predetermined storage area of the memory unit 160 in association with the arm swing angle. In addition to the above-described subjective evaluation information, objective evaluation information such as the temperature and wind speed at the time of running and the road surface condition may be given.

(Arm swing state judgment / support processing)
The arm swing state determination / support processing (step S300) is an operation performed during the second and subsequent running operations as described above. As shown in the flowchart of FIG. 7, the above-described arm posture detection processing (see FIG. 4). As in steps S101 to S104 shown in FIG. 1, first, when the user US activates the terminal 100 and the terminal 200, acceleration data during exercise is detected as needed by the acceleration sensor 110, and angular velocity data is detected by the angular velocity sensor 120. Is detected as needed (step S301). Next, based on the acquired acceleration data, it is determined whether or not the user US is running (step S302). If it is determined that the user US is running (step S302; Yes), the landing timing is determined. It is detected (step S303). Here, the detected landing timing is the start timing (or end timing) in the arm posture tracking operation executed in step S309 described later. Next, when the landing timing is detected in step S303 (step S303; Yes), in step S311 described later, the arm posture data is obtained from a plurality of arm posture data recorded during the tracking operation period for one cycle. The arm swing angle that is the maximum value of the difference is calculated, and the calculated arm swing angle data is stored in the memory unit 160 (step S304).

  Next, the arm swing angle obtained in step S304 is compared with the arm swing angle evaluated by the user US in the above-described arm swing evaluation process and stored in the memory unit 160, and the arm swing is good. It is determined whether or not (step S305). When it is determined that the acquired arm swing angle is equal to or equivalent to the arm swing angle evaluated as being good and the current arm posture is good (step S305; Yes), the terminal 100 The number of steps and pitch acquired based on the acquired sensor data and the value of the arm swing angle described above are displayed as exercise motion information on the display unit 231 of the terminal 200 attached to the forearm (step S306).

  On the other hand, when it is determined in step S305 that the acquired arm swing angle does not match or is not equivalent to the arm swing angle evaluated to be good and the current arm posture is not good (step S305; No) The arithmetic circuit 150 provides the user US with exercise support information for optimizing the determination result and the current arm posture together with the acquired arm swing angle (step S307). Specifically, for example, when the acquired arm swing angle is smaller than the arm swing angle evaluated as being good in the arm swing evaluation process, the arithmetic circuit 150, for example, “ In order to induce a message (judgment result) such as “the swing is small” or to increase the arm swing angle and to guide the current arm posture to an appropriate state (good arm posture), for example “ A message such as “Please shake” (exercise support information such as warnings and cautions) is displayed on the display unit 231 of the terminal 200 and provided to the user US.

  Here, as a method of displaying exercise motion information and exercise support information in steps S306 and S307, one or more preset information may be displayed on the display unit 231 simultaneously or sequentially. It may be a thing. Further, desired information may be displayed simultaneously or sequentially by the user US operating the input operation unit 220. Furthermore, as a method of providing exercise motion information and exercise support information, in addition to the display on the display unit 231 or in place of the display on the display unit 231, the audio unit 232 provides audio information, alarm sound, and the like. Alternatively, vibration information may be provided by the vibration unit 233.

  Next, the arithmetic circuit 150 initializes tracking data in an arm posture tracking operation executed in step S309 described later (step S308). Thereby, the arm posture data acquired by the tracking operation in the previous cycle is cleared, and the timing for starting the tracking operation in the next cycle is set as the landing timing.

  Next, in step S303, when the landing timing is not detected (step S303; No), the arithmetic circuit 150 integrates the angular velocity data detected by the angular velocity sensor 120, thereby completing the period of one step of the running operation. The arm posture change corresponding to one cycle is tracked (step S309). When the arithmetic circuit 150 detects the timing at which the angular velocity calculated at any time becomes the minimum value (step S310; Yes), the arm posture data including the arm position (direction angle) at the timing is sequentially recorded. (Step S311). The arithmetic circuit 150 repeatedly executes such processing in steps S310 and S311.

  On the other hand, when the minimum value of the angular velocity is not detected in step S310 (step S310; No), the process returns to step S301 until the user US ends the sensing operation in the terminal 100 or until the power is turned off. The series of processing operations in steps S301 to S311 described above are repeatedly executed (step S312; No).

  In steps S304 and S305 described above, the method for determining whether or not the arm posture is good based on the acquired arm swing angle has been described. However, the present invention is not limited to this. For example, the temporal change of the arm swing angle during the running operation is obtained, and the change is determined based on whether or not the change of the arm swing angle is within a predetermined range in which the arm posture is evaluated in advance. There may be. In this case, when the change in the current arm swing angle deviates from the predetermined range, as described above, exercise support information such as a warning and a caution is provided to the user US.

  As described above, in the present embodiment, first, based on the sensor data detected by the acceleration sensor 110 and the angular velocity sensor 120 built in the terminal 100 attached to the upper arm of the human body, the user's operation state is running. It is determined whether or not. When it is determined that the vehicle is running, a process for tracking a change in arm posture (that is, angular velocity) is executed with the timing at which the foot landing is detected as a start timing. Thereby, the arm posture at each timing when the angular velocity becomes the minimum value is recorded, and the evaluation information is obtained with respect to the arm swing angle which is the maximum value of the difference of the arm posture data in the period corresponding to one cycle of the arm swing operation. Is granted. Then, based on the arm swing angle to which the evaluation information is given, the arm swing angle acquired in the next and subsequent exercise motions is compared, and based on the comparison result, the arm posture is guided to an appropriate state. Exercise support information is provided to the user.

  Therefore, according to the present embodiment, it is possible to output an index that can accurately determine how much the arm is swinging during an exercise operation such as running. The state can be appropriately transmitted, and exercise support for inducing the state to an appropriate movement state can be performed.

  In particular, during an exercise operation such as running, the arm swing angle is updated as needed every time a foot landing is detected. Therefore, the motion operation state including the arm swing angle is estimated in real time, Can be provided. As a result, changes in arm swing angle and arm posture over time, whether or not stable arm swing is achieved (that is, whether the swing angle of the arm swing is large or small), differences from arm swing in good condition, etc. In addition to being able to grasp and judge in real time, it is possible to quickly provide an improvement method (for example, enlarging the arm swing) for realizing an appropriate motion state.

  In this embodiment, since the terminal for providing exercise motion information and exercise support information to the user has a wristwatch type external shape worn on the forearm (wrist) of the human body, the user can exercise Even during movement, exercise motion information including the number of steps, pitch, and arm swing angle can be favorably acquired without making the user particularly aware. In such a terminal, even when an operation of visually recognizing the display unit is performed, for example, a value acquired at least one cycle before the present time is provided, so that the change in the arm swing state is an exercise. It does not affect movement information or exercise support information.

<Second Embodiment>
Next, a second embodiment of the exercise support apparatus according to the present invention will be described.
In the exercise support apparatus shown in the first embodiment described above, at the terminal 100 attached to the upper arm of the human body, the exercise motion of the user US is based on the sensor data acquired by the acceleration sensor 110 and the angular velocity sensor 120. The configuration has been described in which the exercise motion state including the inner arm swing angle is grasped and the exercise motion information and exercise support information based on the exercise motion information are provided to the user US in the terminal 200 attached to the forearm. In the second embodiment, in a single terminal attached to the upper arm part or the forearm part, the movement operation state including the arm swing angle during the movement operation of the user US is grasped, and the movement operation information and the exercise support information are obtained. It has the structure provided to the user US.

  FIG. 8 is a schematic configuration diagram illustrating an exercise support apparatus according to the second embodiment. Here, FIG. 8A is a schematic diagram showing a state (first example) in which the exercise support device according to the present embodiment is mounted on the upper arm of a human body, and FIG. 8B is a diagram illustrating the present embodiment. It is the schematic which shows the state (2nd example) with which the exercise | movement assistance apparatus which concerns on was mounted | worn with the forearm part of the human body. FIG. 9 is a functional block diagram illustrating a configuration example of the exercise support apparatus according to the present embodiment. Here, the same reference numerals are assigned to the same processes as those in the first embodiment described above, and the description thereof is simplified. FIG. 10 is a conceptual diagram showing an arm posture tracking operation (arm swing state detection operation) executed by the exercise support method according to the present embodiment.

  As shown in FIG. 8A, the exercise support apparatus according to the first example of this embodiment is similar to the above-described first embodiment (see FIG. 1B), and has an upper arm attachment type (or Arm terminal type) and has only terminal 100 attached to the upper arm of user US. Further, as shown in FIG. 8B, the exercise support apparatus 200 according to the second example of the present embodiment is attached to the forearm as in the first embodiment (see FIG. 1C) described above. It has a type (or wristwatch type) external shape, and has only a terminal 200 to be attached to the forearm (wrist) of the user US.

  Specifically, for example, as shown in FIG. 9, the terminal 100 or 200 roughly includes an acceleration sensor (detection unit) 110, an angular velocity sensor (detection unit) 120, an input operation unit 130, and a display unit (information provision). Unit) 141, acoustic unit (information providing unit) 142, vibration unit (information providing unit) 143, and arithmetic circuit (operation state determining unit, arm swing angle calculating unit, arm swing state determining unit, information providing unit) 150. And a memory unit 160 and a power supply unit 180. That is, each of the terminals 100 and 200 according to the present embodiment, in an apparatus having one housing, grasps and determines the exercise operation state including the arm swing angle in the terminal 100 described in the first embodiment described above. And a function of providing both exercise function information and exercise support information in the terminal 200 to the user US. Although not shown, the terminals 100 and 200 may include a communication circuit unit for transmitting / receiving predetermined data to / from an external electronic device by wired or wireless communication.

  Also in the exercise support apparatus having such a configuration, as shown in FIGS. 10A to 10D, similarly to the exercise support method described in the first embodiment, the shoulder joint Na is used as a fulcrum. Based on the angular velocity data, the timing corresponding to the arm swing end when the arm swing direction changes to the reverse direction (for example, DRb direction in the figure) after the upper arm AMa swings to the maximum in one direction (for example, the DRa direction in the figure). It is determined based on the change in the angular velocity ω calculated in the above. Then, during the tracking operation period for one cycle, the maximum value of the difference between the arm posture data is obtained from the plurality of arm posture data acquired at the timing at which the angular velocity ω becomes the minimum value (≈0). Is obtained as the arm swing angle.

  Accordingly, in the present embodiment as well, as in the first embodiment described above, it is possible to accurately grasp and determine how much the arm is waving during an exercise operation such as running, so that the user can The exercise operation state including the swing angle can be appropriately transmitted, and exercise support for guiding to an appropriate exercise operation state can be performed.

  In particular, in the present embodiment, a single terminal is provided with a function for determining and exercising an exercise operation state including an arm swing angle during an exercise operation of the user, exercise operation information and exercise support information to the user US. Since the configuration has both functions, the number of devices to be mounted on the human body can be reduced, and the troublesomeness at the time of mounting and input operation can be reduced.

  Here, in the first example, as shown in FIGS. 8A, 10A, and 10B, since the terminal 100 is mounted on the upper arm AMa, the acquired arm swing angle is When the information providing method for displaying the exercise motion information including the exercise support information based on the exercise motion information and the exercise support information is applied to the display unit 141, it may be difficult or difficult for the user US to visually recognize the display unit 141 during the exercise operation. There is a case. In such a case, in the present embodiment, in addition to the display on the display unit 141 or in place of the display on the display unit 141, sound information, an alarm sound, or the like is generated from the acoustic unit 142. Further, by generating vibration information from the vibration unit 143, the above-described exercise motion information and exercise support information can be appropriately provided to the user US.

  Further, in the second example, as shown in FIGS. 8B, 10C, and 10D, the terminal 200 including the acceleration sensor 110 and the angular velocity sensor 120 is connected to the shoulder joint Na. Since it is attached to the forearm AMb connected via the upper arm AMa and the elbow joint Nb, as shown in the first embodiment and the first example of the present embodiment, it is directly connected to the shoulder joint Na. The estimation accuracy of the arm swing angle may be lower than when detecting the position (direction angle) and angular velocity of the upper arm AMa to be connected. In such a case, in this embodiment, a component specific to the arm swinging motion of the forearm during a running motion such as running is measured or estimated in advance, and the detected directional angle and angular velocity are corrected appropriately. Thus, the arm swing angle can be estimated with relatively high accuracy, and appropriate motion information and exercise support information can be provided to the user.

Functions as an interface. In addition to the function of transmitting / receiving exercise data and evaluation data to / from the terminal 100 or 200, the communication circuit unit 310 has a function of connecting to a network 400 such as the Internet or a LAN (Local Area Network).

Note that the control program executed in the arithmetic circuit 340 may be stored in the memory unit 350 or may be incorporated in the arithmetic circuit 340 in advance.

  The input operation unit 320, the display unit 330, and the power supply unit 360 are respectively the input operation units 130 and 220 of the terminals 100 and 200 and the display units 140, 141, and 231 described in the above embodiments. Since it has the same function as the power supply units 180 and 260, the description thereof is omitted.

  The network server 500 is connected to a network 400 to which the terminals 100 and 200 are connected directly or via the information communication apparatus 300 described above so that data can be transmitted and received. Specifically, for example, as shown in FIG. 12B, the network server 500 generally includes a communication circuit unit 510, an input operation unit 520, a display unit 530, an arithmetic circuit 540, a memory unit 550, A power supply unit 560. Here, the communication circuit unit 510 has a function of connecting to the network 400, and exercise data transmitted from the terminal 100 or 200 is directly transmitted via the network 400 or via the information communication apparatus 300 and the network described above. It functions as an interface for receiving. Further, the communication circuit unit 510 functions as an interface when transmitting the evaluation data read from the memory unit 550 to the terminal 100 or 200 via the network 400.

Since it has the same function as the power supply units 180 and 260, the description thereof is omitted.

  In the exercise support apparatus having such a configuration, as illustrated in FIG. 11, in the configuration in which the terminal 100 or 200 is connected only to the information communication apparatus 300 by wired or wireless communication, the terminal 100 or 200 is exercising. The acquired sensor data and the motion data such as the number of steps, the pitch, and the arm swing angle calculated based on the sensor data are transmitted to the information communication device 300 and stored in the memory unit 350. By displaying the exercise data stored in the information communication device 300 on the display unit 330, the user US assigns evaluation information indicating whether the condition is good or bad to the arm swing angle included in the exercise data.

It is not limited to this. That is, according to the present invention, the above acceleration data may be acquired by attaching a terminal incorporating an acceleration sensor to the trunk of a human body such as the chest and waist. According to this, the posture change is less likely to occur compared to the case where it is worn on the upper arm or the forearm, and the acceleration near the center of gravity of the human body during exercise can be stably acquired. Thus, it is possible to detect an accurate acceleration that is not affected, and to appropriately determine the state of the motion operation and set one cycle of the detection operation.
