The user's target information may be acquired through the second device 200 that is a smart phone or the third device 300 that is a laser output device and stored in the memory.

In the following description, the athletic activity will be described with running as an example, but the physical activity is not limited thereto, and the user's speed (and/or speed) including cycling, marathon, canter, hurdles, triathlon, etc. It may be applied to sports, games, play and/or recreation related to

The user's status information may include, for example, one or more of the user's biometric information, the user's current moving speed, or the elapsed time of the activity. The user's biometric information may include age, height, weight, body fat mass, muscle mass, and the like.

The elapsed activity time may mean running time from the time when the user starts running to the current time that the user is running, and may be acquired by the timer of the second device 200 or the third device 300 .

According to various embodiments, if the difference between the target moving speed and the current moving speed is within the first threshold range, the processor 110 sets the length of the laser to be output as the first length and/or the angle at which the laser is emitted. Output information of the laser (and/or the third device 300 and/or the laser output device) may be generated to be output at one angle. The laser output information generated in this way may be transmitted to the third device 300 which is a laser output device through the transceiver 130 , and the third device 300 may output the laser at a first length and/or a first angle. can

According to various embodiments, when the value obtained by subtracting the current moving speed from the target moving speed exceeds the maximum value of the first threshold range, the processor 110 may output the laser in a second length longer than the first length. Laser output information can be generated. In addition, if the value obtained by subtracting the current movement speed from the target movement speed exceeds the maximum value of the first threshold range, the processor 110 determines that the angle at which the laser is fired is greater than (or less than) the first angle. It is also possible to generate output information of the laser (and/or the third device 300 and/or the laser output device) so that it can be output as a . The laser output information generated in this way is transmitted to the third device 300 which is a laser output device through the transceiver 130 , and the third device 300 may output the laser at a second length and/or a second angle.

According to various embodiments, when the value obtained by subtracting the current moving speed from the target moving speed is less than the lowest value of the first threshold range, the processor 110 outputs the laser so that the laser is output in a third length shorter than the first length. information can be generated. Also, if the value obtained by subtracting the current movement speed from the target movement speed is less than the lowest value of the first threshold range, the processor 110 outputs the laser beam as a third angle with a smaller (or larger) value than the first angle. output information of the laser (and/or the third device 300 and/or the laser output device) may be generated. The laser output information generated in this way is transmitted to the third device 300 which is a laser output device through the transceiver 130 , and the third device 300 may output the laser at a third length and/or a third angle.

Exemplarily, the first length may be 4 [m], the second length may be 8 [m], and the third length may be 2 [m], and the color of the laser may be set to green as a default value. Also, the first angle may be an angle such that a distance to a point where a laser emitted from the third device 300 and/or a laser output device is displayed on the stadium floor and/or road corresponds to the first length, and the second The angle may be such that the distance to the point where the laser emitted from the third device 300 and/or the laser output device is displayed on the stadium floor and/or road corresponds to the second length, the third angle being the second length. 3 It may be an angle such that the distance to the point where the laser emitted from the device 300 and/or the laser output device is displayed on the stadium floor and/or the road corresponds to the third length.

The first threshold range may be directly input by the user. Alternatively, an appropriate candidate range may be pre-stored in the memory according to the target moving speed input by the user, and the first threshold range may be determined by the user selecting one of the appropriate candidate ranges. For example, it is assumed that the target moving speed of the user is 5 [km/h] and the first critical range is 0.1 [km/h]. That is, the lowest value of the first threshold range may be (-)0.1, and the maximum value may be (+)0.1.

For example, if the current moving speed of the user obtained through the speed sensor of the second device 200 or the third device 300 is 4.92 [km/h], the difference between the target moving speed and the current moving speed is the first Since it is within the critical range of 0.1 [km/h], the laser may be output at 4 [m] through the third device 300 .

As another example, if the user's current moving speed is 4.5 [km/h], a value obtained by subtracting the current moving speed from the target moving speed is 0.5. Since this exceeds 0.1, which is the maximum value of the first critical range, the laser may be output at 8 [m] through the third device 300 . That is, by visually recognizing the laser output longer than the first length, the user can recognize that the user's current moving speed is less than the target moving speed, and thus the pace can be adjusted by himself/herself.

As another example, if the user's current moving speed is 5.5 [km/h], a value obtained by subtracting the current moving speed from the target moving speed is (-)0.5. Since this is smaller than (−)0.1, which is the lowest value of the first critical range, the laser may be output as 2 [m] through the third device 300 . That is, by visually recognizing the laser output shorter than the first length, the user recognizes that he or she is running faster than the target moving speed, and reduces the speed to enable pace control.

The values of the length of the laser and the first threshold range are exemplary, the second length and the third length may be set to a plurality of values, and the first threshold range may also be set to a plurality of values. For example, the first threshold range may be set in plurality, such as 0.1 [km/h] and 0.2 [km/h], and accordingly, the second length and the third length are also set in plurality, so that the user's speed changes according to the user's speed change. The length of the laser may be output to become shorter or longer. When a plurality of laser lengths are set according to the plurality of first critical ranges, the user can grasp his/her own pace in real time, thereby enabling more efficient pace control.

According to various embodiments, the processor 110 may acquire the elapsed time of the user's activity through the timer of the second device 200 or the third device 300 .

For example, it is assumed that the target movement time of the user is 2 hours [hour]. The processor 110 continuously receives the elapsed time of the user's activity through the transceiver 130, and when the elapsed time of the activity exceeds 2 hours, the processor 110 transmits the laser output information so that the color of the laser is changed. can create For example, the processor 110 may generate output information such that the default color is changed from green to red. When the laser output through the third device 300 changes from green to red, the user recognizes that he is running longer than the target time, and can adjust the pace by increasing the running speed.

According to various embodiments, the processor 110 may acquire the user's location information through the GPS function of the second device 200 or the third device 300 . The processor 110 may generate new laser output information based on the fact that the linear distance between the user's arrival location stored in the memory 120 and the user's location information acquired through the transceiver 130 is within a second threshold range. . The new laser output information may be, for example, information output by blinking a laser at an interval of 2 seconds, or information output by changing the color of the laser from the default green to blue. The second threshold range may be, for example, 1 [km]. That is, while the user is running, the laser light blinks every 2 seconds or the color changes to blue, so that the user recognizes that he or she is within 1 [km] of the arrival location and recognizes that he has almost arrived at the target point. can do.

An operation method of the present system 1 will be described in more detail with reference to FIGS. 3 to 7 . 3 is an example of the third device 300, that is, a laser output device. The laser output device may include a strap 310 and a main body 320 that can be attached around the user's body, for example, the chest, and the main body 320 is a laser output unit 330 that outputs a laser. ) and an angle adjusting unit 340 for adjusting the angle of the laser output (and/or emitted) from the laser output unit 330 . The laser output through the laser output unit 330 is based on laser output information obtained from the first device 100 through the network 10 . The laser output through the laser output unit 330 is output as shown in FIG. 4 and can be visually recognized by the user. The angle adjusting unit 340 may include at least one of a means for moving the position of the laser output unit 330 and a means for changing an angle.

Referring to FIG. 5 , the first device 100, which is a server for assisting physical activity, receives target information of the user (S510), receives the user's status information (S520), and displays the target information and the status information. By comparison (S530), laser output information may be generated (S540). The laser output information is information that causes the third device 300 to output a laser, and may include the length of the laser, the color of the laser, and/or whether the laser is flickering.

6 shows the length of the laser longer than the first length when the value obtained by subtracting the current movement speed from the target movement speed exceeds the maximum value of the first threshold range, that is, when the user's current movement speed is lower than the target movement speed by a certain level. This is an example of outputting 2 lengths. Also, FIG. 6 may show an example in which a laser is output at a second angle from the third device 300 and/or the laser output device. In this case, the user may recognize his/her own pace and increase the speed by visually recognizing the length of the laser output (and/or the laser displayed at a position far from the user's position).

7 is a third length shorter than the first length of the laser when the value obtained by subtracting the current movement speed from the target movement speed is smaller than the lowest value of the first threshold range, that is, the user's current movement speed is higher than the target movement speed by a certain level. This is an example of outputting as . Also, FIG. 7 may show an example in which a laser is output at a third angle from the third device 300 and/or the laser output device. In this case, the user may recognize his/her pace and reduce the speed by visually recognizing the length of the laser output (and/or the laser displayed close to the user's location).
