1 to 3, the technology training support system 10 for a sledding event includes a sled push characteristic acquisition unit 100, a sled speed calculation unit 110, a virtual environment providing unit 120, and a database unit 130. ).

The technical training support system for a sled event according to the embodiments may have an aspect that is entirely hardware, or partially hardware and partially software. For example, the technical training support system for sledding events of the present specification and each unit included therein may collectively refer to a device for sending and receiving data of a specific format and content in an electronic communication method, and software related thereto. In this specification, terms such as "unit", "module", "server", "system", "device" or "terminal" refer to a combination of hardware and software driven by the hardware. Is intended to be. For example, the hardware here may be a data processing device including a CPU or other processor. In addition, software driven by hardware may refer to an executing process, an object, an executable file, a thread of execution, a program, and the like.

In addition, each unit constituting the technical training support system for the sledding event is not intended to refer to a separate component that is physically separated. In FIG. 1, the sled push characteristic acquisition unit 100, the sled speed calculation unit 110, the virtual environment providing unit 120, and the database unit 130 are shown as separate blocks, but this is a description of the sled type. The devices constituting the training support system are merely functionally classified by the actions performed by the device. Therefore, depending on the embodiment, the sleigh push characteristic acquisition unit 100, the sleigh speed calculation unit 110, the virtual environment providing unit 120, and the database unit 130 may be partially or fully integrated into the same single device. One or more may be implemented as separate devices that are physically separated from other units, or may be components connected to each other to communicate with each other in a distributed computing environment.

The sled push characteristic acquisition unit 100 provides an environment in which at least one user can push while running a sled. In addition, the sled push characteristic acquisition unit 100 may acquire a force acting on the sled as the one or more users push the sled. The user can push the sled 101 for a preset time or a preset distance, and the sled push characteristic acquisition unit 100 the user's force acting on the sled 101 during the time or while moving the distance. Can be obtained.

Specifically, as shown in FIG. 2, the sled push characteristic acquisition unit 100 includes a sled 101, a push member 102, a tread mill 103, and a force sensor (not shown).

The sled 101 may have the same appearance and size as a sled used in an actual sled event, and may also include an internal space in which a user can board. For example, the sled 101 may be a sled applied to a bobsled, skeleton, or luge event. The sled push characteristic acquisition unit 100 may provide a related environment so that a user corresponding to the sport can experience and train the sled.

The sled 101 may be fixed to the lower panel 104 so that it does not advance even if the user provides force. However, the connection member 105 connecting the lower panel 104 on which the sled 101 is disposed and the floor can be used to move the sled 101 in 6 degrees of freedom (movement in the X-axis direction, movement in the Y-axis direction, and Z-axis). It can be configured as a structure that can move according to movement in the direction, rotation about the X axis, rotation about the Y axis, and rotation about the Z axis. That is, while the user experiences and trains a track section to be described later, the sled push characteristic acquisition unit 100 may be configured to provide the user with a motion corresponding to the track section.

The push member 102 is connected to the sled 101 so that at least one user can push the sled 101. The push member 102 may be connected to the sled 101 in a form that enables users to easily push the sled 101. For example, the push member 102 may have a push-bar shape protruding from the sled 101 in one direction, but is not limited thereto. The push member 102 may be connected to the sled 101 in correspondence with the maximum number of people who can experience or train the sled 101 of the corresponding sport. Illustratively, when the sled 101 is a bobsled sled, the maximum number of users is four, so four push members 102 may be connected to the sled 101. At least one or more users may provide a force for accelerating the sled 101 to the sled 101 through the push member 102. That is, the user may provide a force for accelerating the sled 101 while the push member 102 is gripped. The force for accelerating the sled 101 is provided in a state in which the user runs, and the tread mill 103 provides an environment in which the user can run.

The treadmill 103 may be located on the lower panel 104 to which the sled 101 is fixed so that at least one user can run in place. The treadmill 103 may be positioned adjacent to the sled 101 to provide an environment in which at least one user can run. The treadmill 103 may be positioned on the lower panel 104 to correspond to a location where actual athletes are positioned to accelerate the sled in the start section of the sledding event, but is not limited thereto. The position of the lower panel 104 on which the treadmill 103 is installed may be changed according to a user's selection. The treadmill 103 may be provided to correspond to the maximum number of people who can experience or train the sled 101 of the corresponding sport. For example, when the sled 101 is a bobsled sled, since the maximum number of users is four, four treadmills 103 may be provided around the sled 101. As described above, the sled 101 is in a fixed state, and the user can push the push member 102 on the fixed sled 101 by running in place on the treadmill 103. Here, the user running in place on the treadmill 103 may be the same as running in a straight section. Therefore, pushing the push member 102 of the fixed sled 101 as the user runs in place on the treadmill 103 is the sled 101 for acceleration of the sled 101 in the start section of the sled event. May be substantially the same as pushing. As the user pushes the push member 102 of the fixed sled 101 by running in place on the treadmill 103, the user can feel the same sensation as dragging the sled and training the start section.

The force sensor measures the overall force provided to the sled 101 through the push member 102 as the user runs in place on the treadmill 103. The force sensor may be a sensor that detects a deformation amount that measures a mechanical, optical, or electrical change according to the force provided to the sled 101, but is not limited thereto. The force sensor may be a sensor that measures a physical effect (piezoelectric effect, magnetostrictive effect) according to the force provided to the sled 101. That is, through the force sensor, the sled push characteristic acquisition unit 100 may acquire a force acting on the sled 101 as at least one user pushes the sled 101. Data measured over time may be stored in the database unit 130 and may be provided to the sled speed calculator 110.

The sled speed calculation unit 110 converts the force acting on the sled 101 to calculate an expected speed of the sled 101 as one or more users push the sled.

The sled 101 is in a fixed state, but the expected speed of the sled 101 may be calculated based on the force transmitted to the sled 101. The sled speed calculation unit 110 may calculate the expected speed of the sled as shown in Equation 1 below.

Considering that the speed of the start section in the actual sledding event influences the overall result, the estimated speed at the start section (

Repeating the training to increase) can be very important to the user (athlete). Also, the estimated speed (

), and when the speed of the sled is slow, the user feels the sled heavy, and when the speed of the sled is high, the user can feel the sled lightly. Accordingly, a practice or experience environment that is closer to the real world may be provided to the user.

Here, the sled speed calculation unit 110 according to the present embodiment may measure the pressure applied to the push member 102 by the user. When there are a plurality of users and a plurality of push members 102 corresponding to the user, the sled speed calculation unit 110 may measure the pressure applied to each push member 102, respectively. The push member 102 may include a pressure sensor for providing a pressure value to the sled speed calculating unit 110, and the pressure sensor may sense a pressure acting on the push member 102 while the user runs. Exemplarily, the sled speed calculation unit 110 in FIG. 2 may include a pressure sensor (not shown), respectively, the four push members 102 connected to the illustrated sled, and the sled speed calculation unit 110 is each The pressure acting on the push member can be measured from the pressure sensor.

The sled speed calculation unit 110 may evaluate individual push training for the one or more users based on the pressure applied to the push member. That is, the pressure applied to the push member corresponds to the force that the user pushes the sled, and it may be possible to evaluate the magnitude of the individual user's force acting on the sled. In addition, since the pressure applied to the push member while moving a specific time or a specific distance is measured, whether or not the individual user's force is uniformly maintained can be evaluated. In addition, it may be evaluated whether a plurality of users are providing power to the sled 101 together at the same timing. That is, the sled speed calculation unit 110 may provide various evaluations to individual users based on the pressure measured by the push member 102.

The virtual environment providing unit 120 may provide a virtual environment of a sled event to at least one or more users. The virtual environment providing unit 120 may be a head-mounted display (HMD) worn by one or more users, but is not limited thereto. The virtual environment providing unit 120 may provide a virtual environment of a sled event corresponding to the sled push characteristic acquisition unit 100 to a user. For example, when the sled 101 included in the sled push characteristic acquisition unit 100 is a bobsled, the virtual environment providing unit 120 may provide a virtual environment configured based on a bobsled game to the user. That is, the virtual environment providing unit 120 may provide a user with various sleds and various track courses. Users can experience as if they are playing a sledding event in the provided virtual environment.

The virtual environment of the sled event provided by the virtual environment providing unit 120 includes a start section and a track section. The virtual environment providing unit 120 may provide a virtual screen corresponding to a start section of a sled event and a straight section for accelerating the sled in a stopped state to a user as a start section. The start section may correspond to a push time or a push distance of the sled 101 by the sled push characteristic acquisition unit 100. After the user pushes the sled 101 in response to the start section, the user can board the sled, and the track section while boarding the sled enters and can experience the track section.

The virtual environment providing unit 120 may provide the user with a virtual screen that changes as the sled moves along the track after the start section as a track section. The user can experience the sense of speed according to the change of the virtual screen in the track section, and as described above, the sled 101 can move in 6 degrees of freedom corresponding to the track section. Can be provided. That is, the user can experience or train a sledding event in a more realistic sense through the virtual environment providing unit 120.

The database unit 130 may be a space in which data measured by the sled push characteristic acquisition unit 100 and data generated by the sled speed calculation unit 110 are stored. In addition, it is also possible to provide a temporary memory or the like in which the above-described operations can be performed.

Here, the sleigh push characteristic acquisition unit 100 may further include a boarding sensor (not shown) that senses whether at least one user is boarding a sleigh. The boarding sensor can sense the boarding status and boarding time of all users.

The sled speed calculation unit 110 may evaluate individual boarding training for the user based on the boarding time of at least one user from the boarding sensor. In a sledding event, since the boarding time of the sled after the start section, the boarding sequence and boarding time of a plurality of players have a large effect on the overall performance, training not only for the start section but also for the boarding itself is necessary. The system 10 for supporting technical training of a sledding event according to an embodiment of the present invention may provide not only training for the start section of the sledding event, but also training for sledding.

The system 10 for supporting technical training of a sledding event according to an embodiment of the present invention supports specialized technical training and experience in the start section of the sledding event through a sled push characteristic acquisition unit. In addition, through the sled speed calculation unit, various evaluations of the start section are provided to the user so that efficient technical training is performed.

A virtual screen corresponding to a start section of a sled event and a straight section for accelerating the sled in a stopped state may be provided to the user as the start section. While experiencing the start section of the virtual screen, the user may perform in-place running on the treadmill 103 and push the push member 102.

The force sensor measures the overall force provided to the sled 101 through the push member 102 as the user runs in place on the treadmill 103. That is, through the force sensor, the sled push characteristic acquisition unit 100 may acquire a force acting on the sled 101 as at least one user pushes the sled 101.
