Hereinafter, the present invention will be described by way of example of an exercise test service providing apparatus performing a exercise test service providing method according to an embodiment of the present invention, but the present invention is not limited thereto, The inspection service providing method may be performed by a device or two or more devices whose main function is a function other than the exercise test.

Referring to FIG. 1, the exercise test service providing apparatus receives a test result value obtained by performing a test of a predetermined condition (S400).

The examination may be any one of a plurality of examinations preset to be carried out under different conditions, and may be performed in a field or in an indoor exercise device such as a treadmill, It can be a measure of distance.

For example, an examiner or an examinee who conducts the inspection can perform the inspection by selecting any one of "2.4 km Run Test", "12 min Run Test", "M-Bruce Protocol", and "Balke Protocol".

"2.4km Run Test" is a movement test that runs within the shortest distance of 2.4km. It starts at a proper speed on the treadmill when it is examined indoors and adjusts the speed of the subject (or examiner) While measuring the running time of 2.4km.

"12min Run Test" is an exercise test that runs as much distance as possible for 12 minutes. It begins at a proper speed on the treadmill when it is examined indoors, and the subject (or examiner) adjusts the speed to measure the distance depending on the maximum ability of the subject .

On the other hand, the "M-Bruce Protocol" starts running at 11 degrees of inclination at a speed of about 5.3 km / h and measures the time until the subject stops by increasing the stage every minute as shown in Table 1 below .

In addition, the "Balke Protocol" can measure the time until the subject stops until the running speed is fixed at about 5.3 km / h and the slope is increased from 0 degrees to 1 degree per minute.

The test method described above can be selected according to the exercise capacity of the subject. For example, the lower the exercise capacity of the subject is, the more the "2.4 km Run Test", "12 min Run Test", "M-Bruce Protocol" Protocol ".

16, the spare heart rate calculation unit 1230 of the wearable device 1200 acquires information about the age, the stable heart rate, and the maximum heart rate of the wearable device 1200 (step S1510) The user's free heart rate is calculated using the heart rate and the maximum heart rate (step S1610).

For example, the spare heart rate calculation unit 1230 reads the information about the user's stable heart rate and the maximum heart rate from the memory 1240 through the controller 1250 and calculates the maximum heart rate H_max (H_margin) can be calculated by subtracting the age of the user and the stable heart rate (H_stable) from the user's age (Age).

The heart rate measuring unit 1220 measures the current heart rate h of a user wearing the wearable device 1200 (S1530).

For example, the heart rate measuring unit 1220 may measure the user's heart rate continuously in a predetermined cycle using a heart rate measuring sensor provided in the wearable device 1200 so as to be in contact with the user's body (e.g., skin) .

Thereafter, the control unit 1250 displays the exercise intensity of the user based on the current heart rate of the user continuously measured through the heart rate measuring unit 1220 and the spare heart rate of the user calculated by the spare heart rate calculating unit 1230 The color displayed on the display unit 1210 is changed (step S1540).

For example, the controller 1250 calculates a target heart rate using the user's available heart rate (H_margin) and a predetermined exercise intensity, and displays the calculated heart rate on a display unit 1210 ) Can be determined.

Herein, the exercise intensity may be a target exercise intensity selected and set in advance by the user before the exercise, and more specifically, as shown in Table 2 below, a plurality of exercise programs in which the exercise intensity is divided into a plurality of sections May be selected from the user through a user input unit (not shown).

Referring to Table 2, a plurality of exercise programs having different exercise intensities, for example, a "Walking exercise mode", a "Safe exercise mode", a "Diet exercise mode" Training mode ", and the user can select an exercise program according to a desired exercise intensity among a plurality of exercise programs before starting the exercise.

If the Exercise Strength (ES) is set according to the exercise program selected by the user, the user's available heart rate (H_margin), target exercise intensity (ES), and stable heart rate (H_stable) The target heart rate H_target of the user can be calculated.

If the target heart rate (H_target) of the user is calculated using Equation (2) according to the exercise intensity for each exercise program shown in Table 2, the range of the target heart rate H_target for each of the plurality of exercise programs is Can be obtained.

In the case shown in Table 3, the heart rate between 96 and 109 per minute is set as the target exercise intensity range when the user selects the "walking mode" among the plurality of exercise programs, and 109 to 122 The heart rate between 122 and 148 is set as the target exercise intensity range, and when the "cardiopulmonary function mode" is selected, the heart rate between 148 and 147 is set as the heart rate Can be set to the target intensity range.

In the above description, the plurality of exercise programs selectable by the user and the exercise intensity corresponding thereto are set in advance. However, the present invention is not limited to this, and the user may select his or her own exercise program (Custom) mode "can be set directly.

In this case, the control unit 1250 controls the display unit 1210 to display the color displayed on the display unit 1210 according to whether the current heart rate of the user is within the target exercise intensity range corresponding to the specific exercise program (for example, the exercise program selected by the user) You can decide.

FIG. 16 is a flowchart illustrating a first embodiment of a method of changing a hue representing the user's exercise intensity in step S1540 of FIG.

Referring to FIG. 16, the controller 1250 calculates the target heart rate using the available heart rate and the target exercise intensity calculated by the spare heart rate calculator 1230 (step S1610).

For example, the controller 1250 calculates the minimum heart rate / maximum heart rate (H_margin) of the user, the minimum and maximum values of the target exercise intensity (ES) of the exercise program selected by the user, and the heart rate The range of the target heart rate H_target can be obtained from the target heart rate H_stable and the range of the target heart rate H_target can be defined as the minimum value h1 and the maximum value h2.

Thereafter, the controller 1250 checks whether the current heart rate h of the user measured through the heart rate measuring unit 1220 is within the range of the target heart rate h1 to h2 calculated in step S1610 (step S1620) ).

If the current heart rate h of the user is within the range of the target heart rate h1 to h2, the control unit 1250 causes the display unit 1210 to display the first color in operation S1630.

For example, when the current heart rate h of the user is within the range (h1 to h2) of the target heart rate, the controller 1250 controls the display 1250 so that "blue" The control unit 1210 can be controlled.

If the current heart rate h of the user is not within the range of the target heart rate h1 to h2, the controller 1250 determines that the current heart rate h of the user is smaller than the minimum h1 of the target heart rate range (Step S1640).

If the current heart rate h of the user is smaller than the minimum value h1 of the target heart rate range, the controller 1250 causes the display unit 1210 to display the second color in operation S1650.

For example, when the current heart rate h of the user is smaller than the minimum h1 of the target heart rate, the controller 1250 controls the display unit 1210 to display (or blink) the color "green" Can be controlled.

On the contrary, if the current heart rate h of the user is greater than the maximum value h2 of the target heart rate range, the controller 1250 causes the display unit 1210 to display the third color in operation S1650.

For example, when the current heart rate h of the user is larger than the maximum value h2 of the target heart rate, the controller 1250 controls the display unit 1250 so that "red" (1210).

When the user selects "diet exercise mode" among a plurality of exercise programs shown in Tables 2 and 3 and performs a running exercise, the target heart rate range is set to 122 to 148 cycles per minute according to the target exercise intensity range .

In this case, when the current heart rate h of the user measured continuously through the heart rate measuring unit 1220 is within the range of 122 to 148 per minute, the user can see through the display unit 1210 as shown in FIG. 17 (a) "Blue" may be displayed.

On the other hand, when the user's current heart rate h measured through the heart rate measuring unit 1220 falls below 122 per minute, the color displayed on the display unit 1210 is " Green ".

The wearable device 1200 according to an embodiment of the present invention further includes a vibration generating unit (not shown) or a voice output unit (not shown) so that the user's current heart rate is outside the target exercise intensity range Out of range), the user can be notified by vibration or voice.

For example, when the current heart rate h of the user measured through the heart rate measuring unit 1220 falls below 122 per minute, the color displayed on the display unit 1210 as shown in FIG. 17 (b) The sound is changed to "green ", a vibration is generated to warn that the current exercise intensity is weaker than the target exercise intensity and the heart rate is lowered, or a voice containing the warning message may be output.

In this case, the wearable device 1200 reduces the period of the vibration caused by the vibration generator (not shown) or the period of the sound generated by the voice output unit (not shown) .

When the user's current heart rate h measured through the heart rate measuring unit 1220 exceeds 148 per minute, the color displayed on the display unit 1210 is " Red ", and a vibration may be generated to warn that the current exercise intensity exceeds the target exercise intensity and the heart rate is excessively high, or a voice including the warning message may be output.

In this case, the wearable device 1200 increases the period of the vibration generated by the vibration generator (not shown) or the period of the sound generated by the voice output unit (not shown), thereby inducing the user to run more slowly It is possible.

In the above description, an embodiment of the present invention has been described by way of example in which the current exercise intensity of the user is indicated as "moderate", "weak" and "excessive" by using "blue" , The present invention is not limited to this, and the hues according to the current exercise intensity may be changed or arbitrarily set by the user.

FIG. 18 is a flowchart showing a second embodiment of a method for changing the hue representing the exercise intensity of the user in step S1540 of FIG.

18, the control unit 1250 calculates the current exercise intensity using the spare heart rate calculated in the spare heart rate calculation unit 1230 and the current heart rate of the user measured through the heart rate measurement unit 1220 (S1810: ).

For example, the controller 1250 may calculate the current exercise intensity ES from the current heart rate h, the stable heart rate H_stable, and the spare heart rate H_margin, as shown in Equation 3 below.

Thereafter, the controller 1250 changes the color displayed on the display unit 1210 according to the current exercise intensity calculated in step S1810 (step S1820).

There are a plurality of exercise programs divided into a plurality of exercise intensity intervals so as to have different exercise intensities and a plurality of different colors corresponding to each of the plurality of exercise programs may be preset.

In this case, the controller 1250 identifies the exercise program including the current exercise intensity of the user calculated in the step S1810 among the plurality of exercise programs, and displays the color corresponding to the confirmed exercise program on the display unit 1210 Can be controlled.

Taking a plurality of exercise programs having different exercise intensities shown in Table 2 as an example, when the current exercise intensity ES of the user is within the range of 20 to 30%, as shown in FIG. 19 (a) Quot; white "indicating that the user is exercising in the" walking mode "having the strength can be displayed.

On the other hand, when the current exercise intensity ES of the user is within the range of 30 to 40%, "green" as a color indicating that the user is exercising in the "safe mode" is displayed as shown in FIG. 19 (b) Quot; diet mode ", as shown in Fig. 19 (c), if the current exercise intensity ES of the user is within the range of 40 to 60%.

When the current exercise intensity ES of the user is within the range of 60 to 80%, as shown in (d) of FIG. 19, the color of the heart in the "cardiopulmonary function mode" "Red" may be displayed.

As described above, by allowing the wearable device 1200 to display the hue corresponding to the current exercise intensity of the user through the display unit 1210, the user can easily visually confirm the intensity of the current exercise.

Meanwhile, when the color displayed on the display unit 1210 changes according to the current exercise intensity of the user, the wear intensity of the exercise intensity is measured through a vibration generator (not shown) or a sound output unit (not shown) The user may be provided with a vibration or voice to inform the user of the change of the voice.

In the above description, one embodiment of the present invention has been described by way of example showing the change of the current exercise intensity of the user by using "white", "blue", "green" and "red", but the present invention is not limited thereto , The hues according to the current exercise intensity may be changed or arbitrarily set by the user.

According to yet another embodiment of the present invention, the intensity that the user is currently exercising can be visualized and displayed in color, based on the target motion velocity calculated based on the cardiopulmonary ability of the user in the wearable device and the current velocity of the user .

FIG. 20 is a block diagram of a wearable device according to another embodiment of the present invention. The wearable device 1200 includes a display unit 1210, a velocity measurement unit 1260, a target velocity calculation unit 1270 ), A memory 1240, and a controller 1250. [

The description of the configurations of the wearable device 1200 shown in FIG. 20 and the operations thereof that are the same as those described with reference to FIG. 14 to FIG. 19 will be omitted below.

20, the speed measuring unit 1260 measures the speed of the user and transmits the measured speed to the controller 1250. The target speed calculator 1230 calculates a target speed using the at least one value indicating the cardiopulmonary capacity of the user, Calculate the appropriate target speed of motion.

The value representing the cardiopulmonary capacity of the user may be the maximum oxygen capability VO2max and the maximum oxygen capability VO2max of the user may be calculated based on the test result value measured by the user performing the test of a certain condition.

For example, the user's maximum oxygen capability (VO2max) may be determined based on a time or a distance measured by a user at a certain distance or time in the indoor exercise device, according to the exercise test method as described with reference to Figs. . ≪ / RTI >

The method of converting the maximum oxygen capability VO2max of the user into the kinetic velocity may be as described with reference to Figs. 1 to 11, and a detailed description thereof will be omitted below .

Information on the maximum oxygen capability VO2max of the user is stored in the memory 1240 in advance and information on the user's target motion velocity calculated by the target velocity calculator 1230 is also stored in the memory 1240 .

The control unit 1250 displays the exercise intensity of the user based on the current speed of the user continuously measured through the speed measuring unit 1260 and the target exercise speed calculated through the target speed calculator 1270 The color displayed on the display unit 1210 is changed.

Next, another embodiment of a method of displaying intensity of motion in wearable device 1200 in color will be described in more detail with reference to FIGS. 21 to 24.

FIG. 21 is a flowchart illustrating a method of displaying an exercise intensity in a wearable device according to another embodiment of the present invention. The exercise intensity display method shown in FIG. Will be described with reference to a block diagram showing the configuration of the first embodiment.

21, the target speed calculator 1270 of the wearable device 1200 acquires information on the maximum oxygen capability VO2max of the user (step S2110), and acquires the maximum oxygen capability VO2max (Step S2120). The target motion velocity of the user is calculated using the motion velocity of the user.

For example, the target speed calculator 1270 reads information on the maximum oxygen capability VO2max of the user from the memory 1240 through the controller 1250, The maximum oxygen capability (VO2max) of the user can be converted into the optimum exercise speed according to the exercise test method.

The speed measuring unit 1260 wears the wearable device 1200 and measures the current speed v of the user in motion (S2130).

For example, the speed measuring unit 1220 can continuously measure the speed of the user at a preset cycle using a motion measurement sensor provided in the wearable device 1200.

The control unit 1250 then calculates the exercise intensity of the user based on the current speed of the user continuously measured through the speed measuring unit 1260 and the target exercise speed of the user calculated by the target speed calculator 1270 And changes the hue displayed on the display unit 1210 (Step S2140).

For example, the controller 1250 may determine the color displayed on the display unit 1210 according to a result of comparing the target speed calculated from the maximum oxygen capability VO2max with the current speed of the user.

In this case, the controller 1250 can determine the color displayed on the display unit 1210 according to whether the current speed v of the user is within the target exercise intensity range including the target exercise speed V_target.

FIG. 22 is a flowchart showing an embodiment of a method of changing the hue representing the exercise intensity of the user in step S2140 of FIG.

Referring to FIG. 22, the controller 1250 determines whether the current velocity v of the user measured through the velocity measuring unit 1220 is within a range (v1 to v2) of the target motion velocity (step S2210).

The range of the target motion velocity v1 to v2 is defined as a minimum value v1 and a maximum value v2 having a predetermined error range centered on the target motion velocity V_target converted from the maximum oxygen capability VO2max of the user .

For example, when the target motion velocity V_target converted from the maximum oxygen capability VO2max of the user is '10.1 km / h ', the range (v1 to v2) of the target motion velocity ranges from 9 to 11 km / h '.

If the current speed v of the user is within the range of the target motion speed v1 to v2, the control unit 1250 causes the display unit 1210 to display the first color in step S2220.

For example, when the current velocity v of the user is within the range (v1 to v2) of the target motion velocity, the controller 1250 controls the controller 1250 to display (or blink) "blue" The display unit 1210 can be controlled.

If the current speed v of the user is not within the range v1 to v2 of the target exercise speed, the controller 1250 determines that the current speed v of the user is less than the minimum value v1 of the target heart rate range It is checked again whether it is small (step S2230).

If the current speed v of the user is smaller than the minimum value v1 of the target speed range, the controller 1250 causes the display unit 1210 to display the second color in step S2240.

For example, when the current speed v of the user is smaller than the minimum value v1 of the target motion speed, the controller 1250 controls the display unit 1250 to display (or flash) the color "green" 1210).

On the contrary, if the current speed v of the user is greater than the maximum value v2 of the target speed range, the controller 1250 causes the display unit 1210 to display the third color in operation S2250.

For example, when the current speed v of the user is larger than the maximum value h2 of the target motion speed, the controller 1250 controls the display 1250 to display (or flash) the color "red " The control unit 1210 can be controlled.

According to another embodiment of the present invention, the target motion velocity may be set to a plurality of motion programs respectively corresponding to a plurality of exercise programs having different exercise intensity.

For example, as described above with reference to Figs. 1 to 11, a plurality of (including, for example, the " beginner exercise mode ", "intermediate exercise mode ", and" Exercise programs may be offered to the user.

In this case, the target motion velocities corresponding to the " beginner's motion mode ", "intermediate velocity mode ", and" Motion mode ", the target motion velocity can be gradually increased.

When the user selects the " intermediate exercise mode "among the plurality of exercise programs and performs the running exercise, the target exercise velocity is calculated as 10.1 km / h according to the maximum oxygen capability VO2max of the user, The range (v1 to v2) may be set to 9 to 11 km / h.

In this case, when the current speed v of the user continuously measured through the speed measuring unit 1260 is within the range of 9 to 11 km / h, the display unit 1210 "Blue" may be displayed.

On the other hand, when the current speed v of the user measured through the speed measuring unit 1260 drops below 9 km / h, the color displayed on the display unit 1210 as shown in FIG. 23 (b) It can be changed to "green ".

The wearable device 1200 according to an embodiment of the present invention further includes a vibration generator (not shown) or a voice output unit (not shown) so that the user's current speed is outside the target exercise intensity range Speed range), the user can be notified by vibration or voice.

For example, when the user's current velocity v measured by the heart rate measuring unit 1220 falls below 9 km / h, the user's current velocity v is displayed on the display unit 1210 as shown in FIG. 23 (b) A color may change to "green ", vibration may be generated to warn that the current exercise intensity is weaker than the target exercise intensity, or a voice containing the warning message may be output.

In this case, the wearable device 1200 reduces the period of the vibration caused by the vibration generator (not shown) or the period of the sound generated by the voice output unit (not shown) .

When the user's current speed v measured by the speed measuring unit 1260 exceeds 11 km / h, the color displayed on the display unit 1210 as shown in FIG. 23 (c) May be changed to "red ", vibration may be generated to warn that the current exercise intensity exceeds the target exercise intensity and the speed is excessively high, or a voice including the warning message may be output.

In this case, the wearable device 1200 increases the period of the vibration generated by the vibration generator (not shown) or the period of the sound generated by the voice output unit (not shown), thereby inducing the user to run more slowly It is possible.

On the other hand, the controller 1250 identifies an exercise program corresponding to the current speed v of the user among a plurality of exercise programs having different exercise intensities, and displays a color corresponding to the confirmed exercise program on the display unit 1210).

For example, if the current speed v of the user is within the range of 6 to 9 km / h, it indicates that the user is exercising in the "beginner mode" having the weakest exercise intensity as shown in FIG. 24 (a) The color "white" may be displayed.

On the other hand, when the current speed v of the user is within the range of 9 to 11 km / h, "green" which is a color indicating that the user is exercising in the "intermediate mode" is displayed as shown in (b) .

When the current speed v of the user is within the range of 11 to 13 km / h, as shown in (c) of FIG. 24, "Blue" may be displayed.

As described above, by allowing the wearable device 1200 to display the color corresponding to the current exercise intensity of the user through the display unit 1210, the user can visually recognize the intensity of the current exercise considering his or her maximum oxygen capability VO2max As shown in FIG.
