Description

Sphere in a box rescue game device for calculating the diameter of a sphere in a box}

The present invention relates to a sphere-in-a-box rescue game device for finding the diameter of a sphere in a box, and more to a sphere-in-a-box rescue game device for finding the diameter of a sphere in a box, which enables students to directly experience the principle of a sphere system, encourages students to actively participate in classes, and supports students to understand the principles of mathematics in a fun way.

The contents described in this part merely provide background information on the present embodiment and do not constitute prior art.

In the past, most of the classes in the mathematics subject were conducted through injection education, and a method of motivating students through external motivation such as a store/penalty point system was mainly applied.

Such extrinsic motivation has a disadvantage in that the intensity must be continuously increased, and it is difficult to continue to induce motivation, such as the disappearance of motivation factors and the need for learning 　mathematics at the same time.

In addition, in the case of injection-type education, it is difficult to induce active participation of students, and learning by simple memorization of mathematics rather than understanding the principles of mathematics has the disadvantage of reducing the efficiency of learning.

In other words, there is a demand for the development of a device capable of supporting students' motivation for learning mathematics and improving their understanding of mathematics through real experience mathematics contents centered on seeing, touching, and feeling, and exploration.

The rescue game device 10 in a box according to some embodiments of the present invention corresponds to a game device for playing a game for finding the diameter of a sphere stored in a box. In the rescue game in the box according to the embodiment, the sphere may be stored in the box so that only a portion of the sphere is exposed to the outside. The box may accommodate the sphere such that a portion of the sphere is exposed to the outside and the other portion is covered by the box. Students (hereinafter referred to as “users”) using the sphere rescue game device 10 in a box according to the embodiment can experience calculating the diameter of a sphere by using a part of the sphere exposed to the outside and a spherical gauge.

Specifically, referring to FIG. 1 , a rescue game device 10 in a box according to some embodiments includes a game board 100, a first box 110, a second box 120, a first sphere system 130, a second sphere system 140, a first sphere 150, a second sphere 160, and a user device 170.

The game board 100 corresponds to a main space in which the rescue game in a box is performed, and other components of the rescue game device 10 in a box may be arranged.

Referring to FIGS. 2 and 3 , the first box 110 and the second box 120 may be disposed on the game board 100 . The game board 100 may be composed of a space for playing games and a table for supporting other components, but is not limited thereto. In addition, the game board 100 may have a flat top plate, and the process of supporting the operation of the first spherical gauge 130 and the second spherical gauge 140 through this flat top plate, illustratively, the process of determining the reference position can be performed.

In the game board 100, areas for arranging other components may be defined. 2 and 3, a first area S1 corresponds to an area where the first spherical system 130 is disposed, a second area S2 corresponds to an area where the second spherical system 140 is disposed, a third area S3 corresponds to an area where an explanation guide for performing a rescue game in a box is disposed, and a fourth area S4 corresponds to an area where the user device 170 is disposed. Components that transmit important information and control the entire game may be disposed in the third area S3 and the fourth area S4 corresponding to the center of the game board 100 . In addition, for easy utilization of the first spherical system 130 and the second spherical system 140, the first area S1 and the second area S2 may be symmetrically disposed with respect to the third area S3 and the fourth area S4. Also, the first box 110 and the second box 120 may be arranged symmetrically with respect to the third region S3 and the fourth region S4.

The first box 110 and the second box 120 may be configured to accommodate the first sphere 150 and the second sphere 160, respectively. The first box 110 may store the first sphere 150 therein, but may accommodate the first sphere 150 so that a portion of the first sphere 150 is exposed to the outside. Here, the exposed portion of the first sphere 150 may correspond to an area to which the first spherical gauge 130 and the second spherical gauge 140 can be applied. In addition, the second box 120 may store the second sphere 160 therein, but may accommodate the second sphere 160 so that a part of the second sphere 160 appears outside. Here, the exposed portion of the second sphere 160 may correspond to an area to which the first spherical gauge 130 and the second spherical gauge 140 can be applied.

Here, the first sphere 150 may have a first diameter R1, and the second sphere 160 may have a second diameter R2 different from the first diameter R1. The first sphere 150 and the second sphere 160 may have different volumes.

The first box 110 and the second box 120 are externally configured to have the same volume, but since the volumes of the first sphere 150 and the second sphere 160 to be accommodated are different, the configuration and size of the internal space for accommodating them may be different from each other.

The first box 110 and the second box 120 may be configured such that the inside is not visually recognized from the outside. That is, a material constituting the exterior may have an opaque property.

Since the rest of the first sphere 150 except for the portion exposed to the outside is located inside the first box 110, the user cannot check the entire volume of the first sphere 150. In addition, since the rest of the second sphere 160 except for the portion exposed to the outside is located inside the second box 120, the user cannot check the entire volume of the second sphere 160. That is, the user corresponds to a state in which information on which of the first sphere 150 and the second sphere 160 has a larger diameter is currently unknown. The user can check the diameter of the first sphere 150 and the diameter of the second sphere 160 through the first sphere gauge 130 and the second sphere gauge 140 , respectively.

The first spherometer 130 calculates the diameter of the first sphere 150 by using a portion of the first sphere 150 exposed to the outside, or by using a portion of the second sphere 160 exposed to the outside. Corresponds to a device capable of calculating the diameter of the second sphere 160.

4 and 5, the first spherometer 130 is configured at the center of the first tripod 131 and the first tripod 131 and has a straight line distance r with the first tripod 131. It may include a first central pin 132. The first tripod 131 includes three protrusions and may include a support plate connecting the three protrusions. The first central pin 132 is configured to pass through the support plate and may be moved upward or downward based on the support plate. The position where the first center pin 132 is formed corresponds to the position corresponding to the center of the first tripod 131 and the center of the support plate. Here, an equilateral triangle may be defined by three protrusions of the first tripod 131 . That is, the three protrusions may be points corresponding to vertices of an equilateral triangle, and the center of the first tripod 131 may correspond to the midpoint of the equilateral triangle defined by the three protrusions of the first tripod 131 . Since the first center pin 132 corresponds to the midpoint of the equilateral triangle, straight line distances between the protrusions from the first center pin 132 may be the same.

Referring to FIG. 5 , a distance between the first central pin 132 and three protrusions defined through a plane may be defined as a straight line distance r . This straight line distance r may be the shortest distance between the first central pin 132 and the three protrusions of the first tripod 131 . The linear distance r between the first center pin 132 and the three protrusions of the first tripod 131 may be the same because the first center pin 132 corresponds to the midpoint of the equilateral triangle. In addition, the distance between the three protrusions defined through the plane may be defined as the first distance (a). That is, the first distance a corresponds to the length of one side of an equilateral triangle defined corresponding to the first tripod 131 . The first distance (a) may be the shortest distance between the three protrusions.

The first spherometer 130 moves the first center pin 132 to contact the measurement object (sphere) in a state where the first tripod 131 is supported on the measurement object (sphere). It can measure the movement distance information ( h ). That is, the user can calculate the curvature radius and the radius of the measurement object (sphere) through the movement distance information ( h ) of the first center pin 132 and the first distance (a).

Referring to FIG. 6, C1 is a circle showing a sphere corresponding to the measurement target on a plane, A, B, and C are points at which the first tripod 131 is in contact with the measurement target, and D is the first central pin. 132 represents a point in contact with the measurement target. C2 corresponds to a circle corresponding to the first tripod 131 of the first spherometer 130 . B and C may be shown at the same location on a plane. When the radius of the sphere corresponding to the measurement target is defined as R, it is measured as DE = h , EF = 2R - h , and EDA ∝ EAF, so Equation 1 below can be established.

In the triangle AEH, since AE = r, EH = r /2, and AH = a / 2, the following Equation 2 is established.

By substituting Equation 2 into Equation 1 and rearranging, Equation 3 for calculating the radius R of the sphere to be measured according to the first distance a and the moving distance information h can be derived as follows.

That is, when the user obtains the movement distance information of the center pin for the measurement target using a spherometer, the user uses the acquired distance information and the first distance of the spherometer together to calculate the radius of the sphere corresponding to the measurement target through Equation 3. It can be calculated, and the diameter of the sphere corresponding to the measurement target can also be derived.

Here, the second spherical system 140 may include a second tripod 141 and a second central pin 142 configured at the center of the second tripod 141 and having a straight line distance r with the second tripod 141. The second spherical gauge 140 corresponds to a spherical gauge configured to have a different linear distance from the first spherical gauge 130, and may have the same practical function. The straight line distance between the second tripod 141 and the second center pin 142 in the second spherical system 140 may be different from the straight line distance between the first tripod 131 and the first center pin 132 .

The user may use at least one of the first sphere gauge 130 and the second sphere gauge 140 to calculate the diameter of the first sphere 150 or the second sphere 160 to be measured.

Here, the moving distance of the center pin varies according to the straight line distance. When the same sphere is measured by the first spherometer 130 and the second spherometer 140, the measured movement distance information may be different, and the values used for calculation may be different, but the radius of the sphere derived through calculation may be the same. That is, when the diameter of the first sphere 150 is measured using the first sphere gauge 130 and the second sphere gauge 140, respectively, the user can confirm that the same value is derived.

When the diameter of the first sphere 150 is calculated using the first sphere gauge 130 and the second sphere gauge 140, the user can confirm that the same value is derived. If a different value is obtained when measuring the diameter of the first sphere 150 using the first spherometer 130 and the second spherometer 140, an error in measurement or calculation using the spherometer 140 occurs, and the user may be induced to perform the measurement or calculation again. In this way, the sphere rescue game device 10 in a box for obtaining the diameter of a sphere in a box according to an embodiment of the present invention can support a user to experience the calculation of the diameter of the first sphere and the diameter of the second sphere using the first and second sphere gauges, and can support naturally learning the concept and principle of the sphere gauge.

Through data exchange between the user device 170 and other elements, a user environment capable of further supporting the user to learn the principles and concepts of the spherometer may be provided. That is, the user performs the rescue game in the box through the user environment provided by the user device 170, and is induced to become more immersed in and actively participate in mathematical experiential learning.

Referring to FIG. 7 , a user device 170 includes a communication unit 171 , an input unit 172 , a control unit 173 , a display unit 174 and a storage unit 175 .

The communication unit 171 may exchange data with other elements of the rescue game device 10 in a box through a network. The user device 170 may receive data from other components through the communication unit 171 and transmit a signal or command for controlling the other components based on the received data.

Here, the network may include a network based on wired Internet technology, wireless Internet technology, and short-range communication technology. For example, the network may include at least one of a local area network (LAN), long term evolution (LTE), wireless LAN (WLAN), Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), and ZigBee.

The input unit 172 may receive a user's command. The input unit 172 may be a mouse, keyboard, touch panel, touch screen, or touch pad, but is not limited thereto.

The control unit 173 may control the operation of the main components of the box-in-a-box rescue game device 10 . In some embodiments, the control unit 173 may include at least one processor and may perform calculations and data processing required for operation of main components. The controller 173 may implement a user environment supporting a user to play a rescue game in a box. The user environment may support the user to calculate the diameter of the first sphere 150 and the diameter of the second sphere 160 using the first sphere gauge 130 or the second sphere gauge 140 .

A user environment may be provided to the user through the display unit 174 . The display unit 174 may be a display device displaying the user environment.

The storage unit 175 may store data necessary for implementing a user environment. The storage unit 175 may store data or information necessary for the operation of the control unit 173 or data or information according to an operation performed by the control unit 173 .

The first box 110 may include a first storage unit 111 in which the first sphere 150 is stored, a first opening/closing control unit 112 for controlling opening and closing of the first storage unit 111, and a first communication unit 113 for exchanging data with the user device 170 through a network.

In the embodiment, whether the first storage unit 111 of the first box 110 is opened or closed may be determined through the first opening and closing control unit 112. When the first storage unit 111 is in an open state, the storage state of the first sphere 150 may be released, and the first sphere 150 may be separated from the first storage unit 111 . When the first storage unit 111 is in a closed state, the storage state of the first sphere 150 may continue to be maintained, and the first sphere 150 is continuously stored in the first storage unit 111 and only a portion thereof corresponds to a state exposed to the outside. The first opening/closing control unit 112 may selectively control the open state and the closed state of the first storage unit 111 . The first open/close control unit 112 may control the open/close state of the first storage unit 111 in response to a command provided from the user device 170 through the first communication unit 113 .

In the embodiment, whether the second storage unit 121 of the second box 120 is opened or closed may be determined through the second opening and closing control unit 122. When the second storage unit 121 is in an open state, the storage state of the second sphere 160 may be released, and the second sphere 160 may be separated from the second storage unit 121 .

The second opening/closing control unit 122 may control the opening/closing state of the second storage unit 121 in response to a command provided from the user device 170 through the second communication unit 123 .

The user device 170 may provide movement distance information provided through the first spherometer 130 or the second spherometer 140 to the user through the user environment. The user may calculate the radius of the sphere corresponding to the measurement target in consideration of the distance information provided through the user environment and the straight line distance of the spherometers, and multiply the radius by 2 to calculate the diameter. Here, the user environment may provide an interface for the user to input the calculated diameter of the sphere (first sphere or second sphere) corresponding to the measurement target. The user may input the calculated value into the interface, and the control unit 173 of the user device 170 may determine whether the value input by the user is correct. If the value input by the user is correct, the control unit 173 may send a command for controlling the opening/closing control unit to open the storage unit storing the sphere corresponding to the measurement target.

8 to 10 show a process of calculating the diameter of the first sphere 150 through the first spherometer 130 and checking whether the calculated result is correct. The process described later in relation to FIGS. 8 to 10 may also be applied to the process of calculating the diameter of the second sphere 160 through the first spherometer 130 and checking whether or not the calculated result is correct, and the same can be applied to the process of calculating the diameter of the first sphere 150 or the second sphere 160 through the second spherometer 140 and checking whether the calculated result is correct or not.

Referring to FIG. 8 , a method for experiencing a sphere rescue game in a box according to an embodiment of the present invention includes measuring first distance information of a first center pin with respect to a first sphere (S100), measuring second distance information of a first center pin with respect to a game board (S200), inputting a diameter of a first sphere calculated according to specification information, first location information, and second location information of a first sphere meter (S300), and inputting a diameter of a first sphere Controlling opening and closing of the first storage unit according to whether or not the answer is correct (S400) is included.

Although steps S100 and S200 have been described sequentially, the order of operations is not limited to the described order. In some embodiments, step S200 may be performed prior to step S100.

Figure 9 shows the detailed process of step (S100).

In an embodiment, the user environment may provide an interface capable of generating a measurement command for operating the first spherometer 130 . The user may select the interface through the input unit 172 to generate a first measurement command and transmit it to the first spherometer 130 (S110). The third controller 133 of the first spherometer 130 receives the first measurement command through the third communication unit 134 and proceeds with a process for operating the first center pin 132 .

First, the third controller 133 may recognize that the first tripod 131 has contacted the first sphere (S120). The user may bring the first tripod 131 of the first spherometer 130 into contact with an externally exposed portion of the first sphere 150, which is a target to be measured. The third controller 133 may recognize contact between the protrusion and another component (exposed part of the first sphere) through a contact sensor configured on the protrusion of the first tripod 131 .

The third control unit 133 operates the first central pin 132 when it is recognized that all three protrusions of the first tripod 131 come into contact with a portion exposed to the outside of the first sphere 150. The first central pin 132 of the first spherometer 130 may be set to a specific position in a state before being operated, and may be controlled by the third control unit 133 to return to this position when the measurement is completed. The position of the first central pin 132 is defined as an initial position. When the third control unit 133 recognizes that all three protrusions of the first tripod 131 come into contact with a portion exposed to the outside of the first sphere 150, the first center pin 132 is moved downward from the initial position (S130). This movement continues until the first center pin 132 contacts the first sphere 150. When the first center pin 132 comes into contact with a part exposed to the outside of the first sphere 150, the third control unit 133 generates first distance information for which the first center pin 132 has moved from the initial position (S140). By such an operation process through the third control unit 133 of the first spherometer 130, the user can be supported to generate the first distance information using the first spherometer 130, and the generation of accurate first distance information is supported. The third controller 133 may transmit the generated first distance information to the user device 170 through the third communication unit 134 (S150).

10 shows a detailed process of step S200.

The user may select an interface for generating a measurement command through the input unit 172, generate a second measurement command, and transmit the second measurement command to the first spherometer 130 (S210). The third controller 133 of the first spherometer 130 receives the second measurement command through the third communication unit 134 and proceeds with a process for operating the first center pin 132 .

First, the third controller 133 may recognize that the first tripod 131 has contacted the game board 100 (S120). The user may bring the first tripod 131 of the first spherometer 130 into contact with the flat or flat portion of the game board 100, which is a target to be measured. The third controller 133 may recognize a contact between the protrusion and another configuration (a flat area of the game board) through a contact sensor configured on the protrusion of the first tripod 131 .

When it is recognized that all three protrusions of the first tripod 131 are in contact with the game board 100, the third controller 133 moves the first center pin 132 downward from the initial position (S230). This movement is continued until the first center pin 132 contacts the game board 100 . When the first center pin 132 contacts the game board 100, the third control unit 133 generates second distance information about the movement of the first center pin 132 from the initial position (S240). By such an operating process through the third control unit 133 of the first spherometer 130, the user can be supported to generate the second distance information using the first spherometer 130, and the generation of accurate second distance information is supported. The third controller 133 may transmit the generated second distance information to the user device 170 through the third communication unit 134 (S250).

In step S300, first distance information and second distance information may be respectively provided to the user through the user environment. In addition, the user environment may further provide specification information (first distance a) of the first spherical system and principle information of the spherical system. The spherical system principle information corresponds to information for explaining the spherical system principle for calculating the diameter of the first sphere using the first distance (a) and the moving distance information ( h ), which is the difference between the first distance information and the second distance information. The user may calculate the diameter of the first sphere using this information, and may input an interface for inputting the diameter of the first sphere.

In step S400, the control unit 173 may determine whether the input diameter of the first sphere is correct, and may control opening and closing of the first storage unit 111 according to whether or not the input diameter of the first sphere is correct. When the input diameter of the first sphere is correct, the control unit 173 may provide the control unit 112 with a control command to open the first storage unit 111 storing the first sphere 150 when the value input by the user is correct. The opening/closing control unit 112 opens the first storage unit 111 in response to such a control command so that the first sphere 150 escapes to the outside. That is, if the user correctly calculates the diameter of the sphere and gives the correct answer, the sphere trapped in the box is rescued and the user can check the real object of the rescued sphere.

The sphere-in-a-box rescue game device for obtaining the diameter of a sphere in a box according to an embodiment of the present invention can support a user to experience calculating the diameter of the first sphere and the diameter of the second sphere using the first and second spherometers, and can support naturally learning the concept and principle of the spherometer.

In addition, the sphere-in-the-box rescue game device for finding the diameter of the sphere in the box according to the embodiment of the present invention can provide a user environment that can further support the user in learning the principles and concepts of the spherometer, and can induce the user to be more immersed in and actively participate in mathematical experiential learning.
