The present invention relates to a running assist device and a method for instructing an exercise pace in association with music, and more particularly, to a running assist device and method for informing a running pace in real time without relying on a user's vision in connection with music. will be.

Recently, with increasing interest in health, various devices for helping individuals exercise have been developed. In other words, devices are being developed to allow people to achieve their target momentum without getting bored. For example, exercise assistants have been developed to measure individual's health status (eg, heart rate, body temperature, etc.) according to exercise and provide results thereof so that individuals can control their exercise amount while realizing their condition in real time.

In addition, exercise aids have been developed that include portable music players (eg, MP3 players, etc.) that can listen to music during exercise. The exercise assisting apparatus including the music player calculates an exercise amount according to an exercise result or an individual's health state according to the exercise and selects and plays music designated according to the exercise amount.

The conventional exercise assisting device allows the user to adjust the amount of exercise by informing the user of the result of exercise (for example, exercise amount) or the user's physical condition (for example, heart rate, body temperature, etc.) according to the exercise. However, the general user may not know how to effectively control the amount of exercise or the pace of exercise based on the information. In other words, informing the user only of the result of the exercise or the change in the physical condition according to the exercise is not effective for adjusting the exercise amount or the pace of the exercise user.

However, since all of the conventional exercise assisting apparatuses as described above are outputted on the same screen as the display included in the apparatus, the current exercise state or the user's physical state, the user's eyes are moved to the display of the device for reference. There was no choice but to.

However, if your eyes move while running at high speed, there is a risk of safety accidents, and the display can be viewed for a very short time to eliminate such risks. I had to see it again and again.

The present invention provides a running assistance device that can inform the running pace in real time without resorting to time.

1 is a schematic block diagram showing the configuration of the exercise assisting apparatus according to the present invention.

Referring to FIG. 1, the running assistance device 100 according to the present invention includes a speed measuring unit 110, a music storage unit 120, a music player 130, a music output unit 140, and a face storage unit 150. ), And the controller 160.

The speed measuring unit 110 measures the running speed of the user in real time and transmits the same to the controller 160. The speed measuring unit 110 may include, for example, a GPS, an acceleration sensor, a gyro sensor, and the like, but is not limited thereto. In particular, it is desirable to use GPS for accurate speed measurement.

With GPS, distance information from three or more satellites, information about the time at which the distance information was measured, and then the triangulation method is applied to the calculated distance information, so that the latitude, longitude, and Three-dimensional location information according to the altitude can be calculated. Furthermore, since a method of calculating position and time information using three satellites and correcting the error of the calculated position and time information using another satellite is also used, more accurate speed measurement is possible.

The music storage unit 120 is a part in which a music file to be listened to by a user when running is stored. The music file may be an electronic file such as an MP3, and the music storage unit 120 in which the music file is stored may be, for example, a storage device such as an HDD or a flash memory, but is not limited thereto.

The music player 130 is a part where the music file such as the MP3 is played. Typically, the music player is composed of various modules including a codec unit, etc., but the detailed description thereof will be omitted since the present invention uses a conventional music player.

The music output unit 140 is a portion in which music reproduced through the music player 130 is output. The music output unit 140 may be, for example, a speaker or an earphone output unit.

The face storage unit 150 is a part in which a running pace, which is previously designated or planned by a user, that is, a target speed for each section or time is stored. For example, the user may develop a running plan based on time or distance.

Specifically, assuming a user sets a running plan for a total of 20 minutes, for example, 6 km / h for the first 5 minutes, 8 km / h for the next 5 minutes, 10 km / h for the next 5 minutes, and 8 km / h for the last 5 minutes. A plan can be set, and this running plan is stored in the face storage.

In contrast, assuming a user sets a running plan of 4 km in total, for example, the first 1 km is 6 km / h, the next 1 km is 8 km / h, the next 1 km is 10 km / h, and the last 1 km is again 8 km / h. This running plan is stored in the pace storage.

The controller 160 monitors the running speed of the user measured by the speed measuring unit 110 in real time, and compares the running pace of the user with the running pace set by the user and stored in the face storage 150. According to the result, it is a part for adjusting the playback speed of the music played through the music player 130.

Specifically, it will be described on the assumption that the set speed in a specific section (time or distance reference) is x km / h in the face storage unit 150 as described above. If the current speed measured by the speed measuring unit 110 is less than x km / h, the controller 160 causes the user to play the current state by slowing down the playing speed of the music currently being played through the music player 130. Can intuitively indicate that is behind the preset pace. On the contrary, if the current speed exceeds x km / h, the music playback speed can be increased.

More specifically, the present invention is characterized by providing a playback speed adjustment algorithm composed of a multi-step on the basis of the difference between the target pace and the current speed to the target pace.

In reality, since it is impossible to keep the target speed set by the user steadily, it is desirable to provide a margin that does not interfere as much as possible with the user's running or listening to music. Equation (1) below is an expression representing the ratio of the current face to the target face in percentage.

X (%) = {(current velocity)-(target pace)} / (target pace) x 100 --- (1)

Referring to FIG. 2 and Equation (1), in order to maintain a normal playback speed for a small speed change to the user, for example, when the range of X is -10 <X <10%, there is no change in the playback speed, If the range of X is 10 <X <20% or -20 <X <-10%, the playback speed can be set to change to + 10% and -10%, respectively. The numerical values proposed here are exemplary, and the present invention is not limited to these numerical values.

For the convenience of the user, the user can set the values corresponding to the x-axis (X) and y-axis (regeneration rate change rate) of Figure 2 through a separate interface (not shown) provided to the exercise assisting device 100 It is desirable to be able to set accordingly.

For example, the user may set various settings suitable for the user's characteristics such as setting the playback speed to change by ± 5% whenever the range of X changes by ± 5%.

In addition, the present invention is characterized by providing a running assistance device that can reflect the slope present in the actual road or trail. That is, the user who enjoys jogging or running does not necessarily exercise only on a flat track or playground (inclination degree = 0 °), it is preferable to reflect the inclination of the actual road. This is because when running with a constant force, the running speed decreases on the uphill slope, and on the contrary, the running speed increases on the downhill slope.

To this end, the running assistance device 100 according to the present invention may further include an inclination measuring unit 170.

The inclination measuring unit 170 is for measuring the inclination of a road or a trail, and the like, and the inclination measuring unit may use, for example, a GPS or a gyro sensor. In the case of using GPS, the position coordinates of the user are received and compared with the map data to measure the inclination of the current position. In this case, the map data may be stored in advance in a storage unit (not shown) of the running assistance device 100, or may be transmitted from a specific server using an internet network in real time. In addition, in the case of using a gyro sensor, the posture change of the running assistance device 100 including the gyro sensor is sensed in real time to measure the current inclination.

Specifically, according to the present invention, the running speed is slowed in the uphill section, and in contrast, the running speed is adjusted in the downhill section, so that the music playback speed is adjusted.

For example, if the slope (θ) of the current downhill is -2 ° <θ <2 °, the slope is not taken into account and 10% when -5 ° <θ <-2 °, or 2 ° <θ <5 ° By assigning a weight of, the playback speed is set so that the playback speed does not change even if the current speed is 10% faster or slower than the target pace, respectively. The graph shown in FIG. 2 explains that the reproduction speed changes in the case of electrons (−2 ° <θ <2 °). In this case, the slope is not reflected.

The graph shown in FIG. 3 is a graph for explaining the case of downhill slope (for example, -5 ° <θ <-2 °). In this case, the running speed is normal, so it provides a margin of 10%. That is, in this case, the set speed is increased by 10%. Thus, even if the current running speed is 15% faster than the set value, there is no change in the music playback speed, which is different from the example shown in FIG.

On the other hand, the graph shown in FIG. 4 is a graph for explaining the case of the uphill slope (eg 2 ° <θ <5 °). In this case, since the running speed is normal, the setting speed is reduced by 10%. Therefore, even if the current running speed is 15% slower than the set value, there is no change in the music playback speed, which is different from the example shown in FIG. Numerical values provided herein are exemplary, and it is obvious that the user can freely select the inclination and the weight according to the embodiment shown in FIG. 2 described above.

Therefore, according to the present invention, the user can comfortably move at a target pace by correcting an error in speed due to acceleration or deceleration naturally occurring due to the inclination.

In addition, the running assistance device according to the present invention may include a display unit (not shown).

The display unit may be a display device such as an LCD or an LED, and is preferably a touch screen having a touch sensor and capable of touch input.

The display unit may display various information such as music information to be played, current speed information, road surface slope information, current location information, section target pace, current section and pace information, and the like.

In addition, the running assistance device 100 may further include a location measuring unit 180 to display the current location information on the map. The location measuring unit 180 may measure a current location using a GPS or a wireless communication network. When the position measuring unit 180 is configured with GPS, speed measurement and tilt measurement may be simultaneously performed as described above.

In this case, it is possible to provide an exercise report to the user by synthesizing the running route, the running distance and the time in conjunction with the map information.

According to another aspect of the present invention, the present invention provides a running assistance method using the above-described running assistance device.

4 is a schematic flowchart illustrating a running assistance method according to the present invention.

Referring to Figure 4, the running assistance method according to the present invention comprises the first step (S200) of setting the running pace, the second step (S210) of selecting and playing music to listen to the running, monitoring the running speed in real time A third step (S220), a fourth step (S230) for monitoring the inclination of the road surface, and a fifth step (S240) for adjusting the playback speed of the reproduced music according to the running speed.

The first step is to set the running pace (S200), wherein the running pace is preferably set to include one or more of the running time, running distance, running speed. Detailed description of the setting of the running face is the same as described above, and thus will be omitted.

In addition, by monitoring the current running speed in real time (S220) in the third step, if the current speed is faster than the speed set in the first step, music is played quickly, and the current speed is set in the first step. If it is slower than one speed, it can play slowly, so that the current running state can be intuitively conveyed to the user. Since the mechanism for changing the music reproduction speed according to the running speed is as described above, a detailed description thereof will be omitted.

In addition, in the fourth step, by monitoring the slope of the current road surface in real time (b230), even if the current speed becomes faster on the downhill slope, on the contrary, even if the current speed decreases on the uphill slope, the play speed of the music is not affected. desirable. The mechanism for measuring the inclination of the road surface and the music reproduction speed change in consideration of the inclination is as described above, and thus a detailed description thereof will be omitted.

According to the present invention, the user can intuitively recognize the current running speed or pace without looking at a separate terminal, so that the user can enjoy jogging, running, and the like safely on a road, a trail, or the like.
