[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0027] The key concept of the utility model is that a sensing module is embedded in the balance board, which can sense the three-axis acceleration data of the balance board in real time and transmit it to the device end; so that the device end obtains the change of the three-axis offset and controls the designated object accordingly.

[0028] Please refer to Figure 1 as well as Figure 2 The utility model provides a balance board 100, such as Figure 1 As shown, it includes: a balance board body 101, an elastic member 102 and a sensing module 103; the elastic member 102 is arranged below the balance board body 101; the sensing module 103 is embedded in the balance board body 101;

[0030] From the above description, it can be seen that the beneficial effect of the utility model is that: the balance board provided by the utility model is embedded with a sensing module, which can sense the three-axis acceleration data of the balance board in real time and transmit it to the device end; so that the device end can use the received three-axis acceleration data to calculate and obtain the change of the three-axis offset, and accordingly control the designated object, so as to achieve the effect of the human body performing somatosensory control on the designated object in the device end through the balance board, thereby improving the authenticity and sense of immersion of the somatosensory interaction and increasing the fun of human-computer interaction.

[0031] Furthermore, the main control IC is provided with one or more different communication units; the communication unit is a Bluetooth communication unit, a ZigBee communication unit, an infrared communication unit, a radio frequency communication unit, a cellular mobile communication unit, a wireless local area communication unit or a Z-Wave communication unit.

[0032] From the above description, it can be seen that one or more different communication units can be set in the sensing module to establish a connection relationship with external devices in various wireless communication methods, reduce wiring, and be more convenient and practical; in particular, it can also support multiple wireless connection methods at the same time to better meet the needs of various usage scenarios and improve practicality.

[0033] Further, such as Figure 2 As shown, the sensing module 103 further includes an indicator light 143; the indicator light 413 is connected to the main control IC 133 to indicate the communication connection status of the sensing module.

[0034] It can be seen from the above description that the setting of the indicator light makes it easy for the user to intuitively understand the communication connection status of the sensing module, thereby improving the convenience of operation.

[0035] Furthermore, the three-axis acceleration sensor and the main control IC are connected using an IIC communication protocol.

[0036] From the above description, it can be seen that the IIC communication protocol is used for data communication between the three-axis acceleration sensor and the main control IC. On the one hand, it has the characteristics of simple lines, and the implementation of hardware connection is simpler and more economical; on the other hand, it also has the characteristics of stable and efficient communication, which can reduce errors and interference in data transmission.

[0037] Furthermore, the balance board body is a circular board body or a rectangular board body.

[0041] Furthermore, the sensing module is embedded in the middle of the balance board body.

[0042] From the above description, it can be seen that the design in the center is not only conducive to better establishing the corresponding relationship between the coordinate system of the three-axis acceleration sensor in the sensing module and the coordinate system of the balance board body, but also can reduce the force and increase the life of the sensing module.

[0043] Furthermore, the sensing module is an overall cylindrical structure.

[0044] From the above description, it can be seen that the cylindrical structure design is easier to implement, easier to embed into a conventional balance board, and more versatile.

[0045] Please refer to Figure 3 The utility model provides a somatosensory interaction system based on a balance board, such as Figure 3 As shown, it includes: a device end 200 and the above-mentioned balance board 100; the balance board 100 is connected to the device end 200 through the communication unit 1331.

[0046] Furthermore, the device end is a television, a tablet, a mobile phone or a computer.

[0047] From the above description, it can be seen that the balance board of the present invention senses the three-axis acceleration data of the balance board in real time and transmits it to the device end; so that the device end can use the received three-axis acceleration data to calculate the change of the three-axis offset, and control the designated object accordingly, thereby achieving the effect of the human body performing somatosensory control on the designated object in the device end through the balance board, thereby improving the authenticity and sense of immersion of users in somatosensory interactive applications and increasing the fun of human-computer interaction.

[0048] Please refer to Figure 1 and Figure 2 , Embodiment 1 of the present utility model is:

[0049] This embodiment provides a balance board, such as Figure 1 As shown, it includes a balance board body 100, an elastic member 102 and a sensing module 103; the elastic member 102 is disposed below the balance board body 101; the sensing module 103 is embedded in the balance board body 101;

[0050] like Figure 2 As shown, the sensing module 103 includes a start button 113, a three-axis acceleration sensor 123 and a main control IC 133; the start button 113 and the three-axis acceleration sensor 123 are respectively connected to the main control IC 133; the main control IC 133 is provided with a communication unit 1331; the coordinate system of the three-axis acceleration sensor 123 corresponds to the built-in coordinate system of the main control IC 133.

[0051] In this embodiment, the balance board body is used for the user to press two hands or two feet thereon; the elastic member is used to cooperate with the balance board body to create an imbalance of the balance board body.

[0052] In this embodiment, if Figure 1 As shown, the sensing module 103 is preferably disposed in the middle of the balance board body 101 to ensure that the collected three-axis angle offset change data has a high accuracy.

[0053] In this embodiment, the sensing module needs to be placed in a specified manner when embedded in the balance board body, such as Figure 1 As shown, ensure that the arrow on the sensing module 103 is aligned with the arrow on the balance board body 101, thereby ensuring that the coordinate system of the three-axis acceleration sensor corresponds to the coordinate system of the sensing module and the balance board body, so that when the balance board is angularly offset under the operation of the user, the three-axis acceleration sensor in the sensing module can sense the corresponding changes on the corresponding three axes and collect accurate three-axis acceleration data; thereby ensuring that the user's somatosensory control is accurately linked to the specified object in the device end.

[0054] Specifically, the sensing chip IC in the three-axis acceleration sensor has a positioning point, and the three-axis acceleration sensor is fixed with the direction of the main control IC in the sensing module according to the positioning point. Since the assembly direction of the main control IC in the sensing module is fixed, the X, Y and Z axes of the three-axis acceleration sensor correspond to the X1, Y1 and Z1 directions of the sensing module; accordingly, the outer surface of the sensing module product will also be provided with a positioning point to mark the X1 positive direction of the sensing module. At the same time, the outer surface of the sensing module product also has positive and negative direction marks to mark the Z1 positive direction of the sensing module. Combined with the above two marks of the sensing module, the coordinate axis of the sensing module can be matched with the coordinate axis of the balance board body when the sensing module is embedded in the balance board body. At this point, the coordinate system correspondence between the three-axis acceleration sensor, the sensing module and the balance board is successfully established to ensure that the weight acceleration on the three axes of the three-axis acceleration sensor changes according to the rotation angle of the balance board.

[0055] In this embodiment, the specific way for the user to operate the balance board can be: placing both hands or both feet on the balance board body and seeking balance. During the above operation, the three-axis acceleration sensor in the sensing module will sense the acceleration data of the balance board body on the three axes in real time and transmit it to the device end. The device end can use the received three-axis acceleration data to calculate the change of the three-axis offset, and control the designated object accordingly, so as to achieve the effect of the human body controlling the designated object on the device end through the balance board.

[0056] In this embodiment, the start button is used to wake up the main control IC after being triggered; the three-axis acceleration sensor is used to collect the three-axis angle offset in real time and transmit it to the main control IC; the main control IC is used to establish a communication connection with the device end, and receive the three-axis angle offset of the three-axis acceleration sensor and transmit it to the device end.

[0057] In some specific implementations of this embodiment, the main control IC is provided with one or more different communication units; the communication unit may be a Bluetooth communication unit, a ZigBee communication unit, an infrared communication unit, a radio frequency communication unit, a cellular mobile communication unit, a wireless local area communication unit or a Z-Wave communication unit. In other words, the main control IC communicates with the device end in a wireless manner, which is more convenient to use; and multiple wireless communication units can be configured at the same time to support multiple wireless communication protocols, so that users can flexibly select the best communication method according to the specific usage scenario, which is more diverse and practical.

[0058] In some other specific implementations of this embodiment, the sensing module is further provided with an indicator light, which is connected to the main control IC and is used to indicate the communication connection status of the sensing module. Optionally, the indicator light can be configured to indicate that a communication connection is successfully established with the device end. Optionally, the indicator light is a red and blue dual-color LED indicator light, the red light indicates that the sensing module is working; the blue light indicates the communication connection status with the device end, such as slow flashing if not connected, and fast flashing if successfully connected.

[0059] In some specific implementations of this embodiment, the three-axis acceleration sensor and the main control IC are connected using the IIC communication protocol. Preferably, the main control IC collects the three-axis acceleration data of the three-axis acceleration sensor at a sampling frequency of 20 Hz based on the IIC communication protocol.

[0060] In some other specific implementations of this embodiment, the balance board body can be a circular board body or a rectangular board body or other special-shaped boards to support personalized customization. Optionally, a handle can be provided on both sides of the balance board body, which is more convenient for the user to operate with both hands. It is preferred to directly open two corresponding arc-shaped through holes on both sides of the balance board body, so that the user's four fingers can pass through the arc-shaped through holes to hold the balance board body tightly, thereby reducing the difficulty of operation.

[0061] In some other specific implementations of this embodiment, the elastic member may be an arc-shaped hemisphere, a sphere, or an elliptical sphere, and the number of the elastic member may be one or more, and personalized customization is also supported. Preferably, the elastic member is disposed directly below the balance board body to cooperate with the balance board body to provide the user with the best experience of controlling the balance board.

[0062] Please refer to Figure 3 , Embodiment 2 of the present utility model is:

[0063] like Figure 3 As shown, this embodiment provides a somatosensory interaction system based on a balance board, including a device end 200 and the balance board ( Figure 3 The balance board is connected to the device end 200 via the communication unit 1331 therein.

[0064] In this embodiment, the device end 200 can be any intelligent terminal device such as a television, a tablet, a mobile phone or a computer that can establish a communication connection relationship with the balance board.

[0065] Preferably, the APP pre-loaded in the device side may be any somatosensory human-computer interaction application related to the sense of balance, such as game applications related to surfing, skiing, etc.

[0066] The working principle of the somatosensory interaction system based on the balance board provided in this embodiment is as follows: after the main control IC 133 of the sensing module 103 in the balance board is awakened by the start button 113, the sensing module 103 will enter the broadcast state and wait for connection with the APP in the device end 200, and after the connection is successful, the main control IC 133 uses the IIC method to communicate data with the three-axis acceleration sensor 123, specifically collects the three-axis acceleration data of the three-axis acceleration sensor 123 at a certain sampling frequency, and then uploads it to the APP of the device end 200 according to the customized wireless / wired communication protocol; the APP converts the received three-axis acceleration data to obtain the corresponding three-axis angle offset change, that is, the Euler angle of the balance board; then, the APP applies the obtained three-axis angle offset change to the specific somatosensory interaction game, so as to achieve the effect of human body controlling the specified object in the APP through the balance board, thereby improving the authenticity and sense of immersion of the somatosensory interaction and adding fun to human-computer interaction.

[0067] In some specific implementations of this embodiment, after the balance board sends the collected three-axis acceleration data ACCX, ACCY and ACCZ to the device end via wired or wireless means, the app application in the device end will calculate and obtain the offsets of the X-axis, Y-axis and Z-axis based on the three-axis acceleration data ACCX, ACCY and ACCZ; then, the corresponding quaternion quaternion is obtained based on the calculated offset, and then substituted into the interface function to continuously update the quaternion of the specified three-dimensional object in the APP and approach the quaternion, so that the specified object in the screen has the same movement trend as the human body on the balance board, thereby achieving the effect of somatosensory control.

[0068] The specific calculation process of obtaining the corresponding three-axis offset based on the three-axis acceleration data ACCX, ACCY and ACCZ is as follows:

[0069] (1) First calculate the square root SQRT1 of ACCY and ACCZ: SQRT1 = sqrt(ACCY*ACCY+ACCZ*ACCZ);

[0070] (2) Find the arc tangent of the quotient of ACCX and the square root SQRT1, that is, the X-axis radian α: α = atan(SQRT1);

[0071] (3) Calculate the pitch angle using the formula (angle = radians * 180 / π): pitch = α * 180 / π;

[0072] (4) First calculate the square root SQRT2 of ACCX and ACCZ: SQRT2 = sqrt(ACCX*ACCX+ACCZ*ACCZ);

[0073] (5) Find the arc tangent of the quotient of ACCY and the square root SQRT2, that is, the X-axis radian β: β = atan(SQRT2);

[0074] (6) Calculate the roll angle roll using the formula (angle = radian * 180 / π): roll = β * 180 / π;

[0075] (7) Normalize the roll angle roll to obtain the X-axis offset Axisx, which has a value range of [-1, 1];

[0076] (8) Normalize the pitch angle pitch to obtain the Y-axis offset AxisY, which has a value range of [-1, 1];

[0077] (9) Considering the yaw angle yaw as 0, the Euler angles (yaw, pitch, roll) are obtained by combining the normalized roll angle roll and pitch angle pitch;

[0078] (10) The Euler angle is converted into a quaternion, and then substituted into the interface function so that the quaternion of the specified three-dimensional object in the APP is continuously updated and approaches the quaternion, so that the specified object in the screen has the same movement trend as the human body on the balance board, thereby achieving the effect of somatosensory control.

[0079] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
