The invention will be further illustrated by the following detailed description in conjunction with the accompanying drawings.

detailed description

The somatosensory interaction system provided by the present invention and the somatosensory interaction method using the somatosensory interaction system will be further described below with reference to the accompanying drawings and specific embodiments.

Referring to FIG. 1 , a first embodiment of the present invention provides a somatosensory interaction system 100 that includes a somatosensory control device 10 and an intelligent electronic device 20 that wirelessly communicates with the smart electronic device 20 . Interaction.

The somatosensory control device 10 can sense static azimuth information as well as motion posture information. The somatosensory control device 10 includes an attitude sensing module 12 , a transmission module 14 , and a power module 16 .

The attitude sensing module 12 includes an attitude sensor 120 and an attitude data processor 122 for sensing physical motion posture information. Generally, the motion posture information is embodied in the form of an electrical signal. The posture sensor 120 may include a plurality of sensors for sensing different types of motion posture parameters. In the embodiment of the present invention, the posture sensor 120 may be a nine-axis sensor including a three-axis acceleration sensor and a three-axis gyro sensor. And a three-axis geomagnetic sensor. The nine-axis sensor itself is configured with a three-dimensional coordinate system to acquire acceleration, angular velocity, and magnetic field orientation information of the motion posture in three-dimensional space.

Referring to FIG. 2, the gesture data processor 122 may be a microprocessor (MCU) for receiving and processing motion posture information sensed by the attitude sensor 120 to obtain motion posture data. Specifically, motion posture information as an electrical signal is converted into digital information (the motion posture data). Preferably, the gesture data processor 122 can include a data filtering module 1220, a posture solving module 1222, and a data fusion module 1224 that are sequentially connected. The data filtering module 1220 is configured to filter the motion posture information sensed by the posture sensor 120 to remove noise such as noise. The data filtering module 1220 can be implemented by a commonly used filter, which can be, but is not limited to, Kaman filtering. The attitude solving module 1222 receives the filtered motion posture information and performs solution to obtain initial motion posture data, where the initial motion posture data includes an initial acceleration, an initial angular velocity, and an initial magnetic field orientation. The data fusion module 1224 mutually corrects according to the mutual relationship between the initial motion posture data to obtain secondary motion posture data. The data fusion method may be, but not limited to, an adaptive kalman data fusion algorithm. There are some disadvantages to using a three-axis accelerometer sensor, a three-axis gyro sensor, and a three-axis geomagnetic sensor to detect a motion profile alone. For example, the accelerometer sensor cannot establish absolute or relative heading and is too sensitive to motion. The gyro sensor typically does not provide an absolute reference and its bias will drift over time. The main problem with the triaxial geomagnetic sensor is that it measures all magnetic fields, not only the earth's magnetic field, but the detection results are disturbed. The function of the data fusion module 1224 is to complement the advantages of the three-axis accelerometer sensor, the three-axis gyro sensor, and the three-axis geomagnetic sensor, and adjust the detected data to each other to obtain more accurate motion posture data. Solving the problem that the three-axis gyro sensor has no absolute reference and zero offset drift, for example, by jointly applying the three-axis accelerometer sensor and the three-axis geomagnetic sensor to provide heading, tilting, and scrolling for the three-axis gyro sensor Long-term absolute benchmark.

Further, the gesture data processor 122 can include a data conversion module 1226 to convert the initial motion pose data or the secondary motion pose data into absolute motion pose data relative to the surface.

The attitude data processor 122 is integrated with the attitude sensor 120, that is, the attitude data processor 122 and the attitude sensor 120 are integrally packaged in the same chip to better reduce the volume and reduce power consumption.

Referring to FIG. 1 and FIG. 3 , the transmission module 14 is configured to implement wireless interaction pairing between the somatosensory control device 10 and the intelligent electronic device 20 , and the motion posture data may be implemented. In the example, the absolute motion posture data is transmitted to the intelligent electronic device 20 for recognition processing. The transmission module 14 includes a data transmission module 140 and a data transmission controller 142. The data transmission module 140 is configured to receive the motion posture data output by the attitude sensing module 12 and transmit the motion posture data to the intelligent electronic device 20. The data transfer controller 142 is coupled to the data transfer module 140 to control data transfer by the data transfer module 142. By independently providing the data transmission module 140 with the data transmission controller 140 to control data transmission, data transmission can be realized efficiently and quickly, thereby improving the accuracy and real-time performance of subsequent motion recognition.

The data transmission module 140 can be at least one of a wireless communication module, an infrared module, and a Bluetooth module.

Further, the transmission module 14 includes a data transmission storage module 144 for storing motion posture data transmitted by the attitude sensing module 12. The data transfer book module 144 can be implemented by a flash memory (Flash Ram).

The data transmission module 140, the data transmission controller 142, and the data transmission storage module 144 are preferably integrated in the same chip to reduce the size and power consumption. In the embodiment of the present invention, the data transmission module 140, the data transmission controller 142, and the data transmission storage module 144 are an integrated circuit chip.

Referring to FIG. 1 and FIG. 4 , the power module 16 is connected to the attitude sensing module 12 and the transmission module 14 , and supplies power to the attitude sensing module 12 and the transmission module 14 . The power module 16 can include a battery 160, a charging circuit 162, and a power management circuit 164. The battery 160 supplies power to the attitude sensing module 12 and the transmission module 14. The kind of the battery is not particularly limited, and is preferably a secondary battery such as a lithium ion battery. More preferably, it is a micro secondary battery such as a coin battery.

The charging circuit 162 is used to charge the battery 160. The power management circuit 164 is used to control the power supply and charging process of the battery 160. In addition, the power management circuit 164 can adjust external power supply of the battery 160 according to the usage environment and working conditions of the somatosensory control device 10, thereby implementing different power consumption modes, such as when the motion control device 10 is in standby mode. The power management circuit 164 controls the somatosensory control device 10 to enter a low power consumption mode, thereby effectively extending the use time and life of the battery 160.

The attitude sensing module 12, the transmission module 14 and the power module 16 can be integrated with the somatosensory control device 10 disposed on the flexible circuit board to form a miniature. Since the size of the body control device 10 can be small and the volume can be in the range of 2 cm 3 to 7 cm 3 , it is easy to apply to various environments in which a motion posture is required to be sensed.

The prompting device may be at least one of a vibrator, a sounder, and an indicator light.

Referring to FIG. 5 , the somatosensory control device 10 can further include a body 18 as a package structure for encapsulating each module in the somatosensory control device 10 . Preferably, the body 18 can be a wearable structure such as a wristband, a toe ring, a wristband or a finger ring. The somatosensory control device 10 in the embodiment of the present invention is a wristband. In addition, the body 18 can also be a patch structure, such as a sticker.

The somatosensory control device 10 can be carried by a carrier, which in turn can sense the static and dynamic motion posture of the carrier. Any carrier that involves an action or movement may be suitable for use in the present invention. The carrier can be, but is not limited to, an organism as well as a sports equipment. The manner in which the somatosensory control device 10 is carried by the carrier may be, but not limited to, worn, attached, or inlaid. In the embodiment of the present invention, the carrier is a human body, and the user can wear, attach or hold the somatosensory control device 10 to detect the motion posture of the user.

The posture control processor 10 provided by the present invention specifically processes the motion posture data sensed by the attitude sensor 122, and the data transmission controller 142 exclusively processes and controls the data transmission module. 140 and the transmission of the motion posture data greatly improve the motion attitude data sensing, calculation, and data transmission speed, and reduce the inaccuracy rate of motion recognition caused by the delay, thereby improving the sensing motion of the motion sensing device 10. The sensitivity of the gesture and the real-time nature of the motion recognition greatly improve the user experience.

The smart electronic device 20 and the somatosensory control device 10 are physically separate and independent devices. The independent of each other means that the smart electronic device 20 and the somatosensory control device 10 can be used independently to perform respective functions. The somatosensory control device 10 can be mounted or carried on a motion carrier that monitors or processes motion pose data of the motion carrier sensed by the somatosensory control device 10.

The electronic device controller 26 converts the received motion posture data into a motion recognition parameter corresponding to the motion parameter format, and compares the preset motion parameter to identify the motion, and queries the corresponding motion according to the identified motion Operation instructions.

Further, the smart electronic device 20 includes an orientation sensor 28 to sense the orientation of the smart electronic device 20 itself. The orientation sensor 28 can be used in conjunction with the attitude sensor 120 to obtain a relative position between the somatosensory control device 10 and the intelligent electronic device 20. The orientation sensor may be at least one of a position sensor (such as a geomagnetic sensor), a GPS, and a network communication module. The smart electronic device 20 is preferably a portable electronic device, which may be, but is not limited to, a mobile phone, a smart TV, a tablet or a notebook computer.

Referring to FIG. 7, the somatosensory interaction system 100 may further include a plurality of the somatosensory control devices 10, which may be disposed on different carriers or at different locations of the same carrier. The plurality of the somatosensory control devices 10 can be paired with the smart electronic device 20 through the respective transmission modules 14 respectively, so that the motion posture data identification sensed by the plurality of the somatosensory control devices 10 can be realized simultaneously or sequentially.

Referring to FIG. 8, a second embodiment of the present invention further provides a somatosensory interaction method using the somatosensory interaction system 100, and the method includes the following steps:

S1, pairing the somatosensory control device 10 and the smart electronic device 20;

S2, the somatosensory control device 10 senses motion and acquires motion posture data;

S3, the motion posture data is transmitted to the smart electronic device 20;

S4, sensing orientation data of the smart electronic device 20;

S5, correcting the motion posture data according to the orientation data to obtain relative motion posture data of the somatosensory control device 10 with respect to the smart electronic device 20;

S6, the smart electronic device 20 identifies an actual action according to the relative motion posture data, and

S7. The intelligent electronic device 20 issues a corresponding instruction according to the identified actual action to perform a corresponding operation.

In the above step S1, the somatosensory control device 10 and the smart electronic device 20 can perform connection and identification pairing through Bluetooth, infrared, wireless network, and the like.

The step S2 may further include:

S21, the somatosensory control device 10 senses the motion posture information through the attitude sensor 120;

S22, the attitude data processor 122 obtains the second motion posture data by filtering, posture solving, and data fusion.

S23. Convert the secondary motion posture data into absolute motion posture data with respect to the ground surface.

In the above step S22, both the motion posture information and the secondary motion posture data are data obtained based on the three-dimensional coordinate axis established by the posture sensor 120 in the three-dimensional space with itself as the origin. The absolute motion pose data with respect to the ground surface can be obtained by the data conversion of step S23. The motion pose data with higher accuracy and precision can be obtained by data fusion. The filtering, attitude solving and data fusion methods can be implemented for commonly used motion data processing algorithms. The motion posture data in the embodiment of the present invention is absolute motion posture data.

In the above step S2, the motion posture data corresponds to the type of the posture sensor 120. As described above, in the embodiment of the present invention, the motion posture data includes acceleration, angular velocity, and geomagnetic orientation of the somatosensory control device 10 in a three-dimensional space.

In the above step S2, a plurality of pieces of the motion posture data may be further detected, and then the plurality of pieces of data are integrated to determine the final motion posture data. In the embodiment of the present invention, up to 100 strokes of the motion posture data can be acquired per second.

After receiving the motion posture data, the step S3 may further include the step of filtering, by the smart electronic device 20, the motion posture data. The filtering of the intelligent electronic device 20 can further filter out noise to obtain higher-precision motion posture data.

In the above step S4, the smart electronic device 20 can sense the orientation of the smart electronic device 20 by using the orientation sensor 28 to obtain the orientation data.

The purpose of the above step S5 is to acquire the relative position between the somatosensory control device 10 and the intelligent electronic device 20, thereby acquiring the relative motion posture data of the somatosensory control device 10 with respect to the smart electronic device 20. In the embodiment of the present invention, the relative motion posture data includes a relative motion direction, a relative acceleration, and a relative angular velocity. Since the acceleration and the angular velocity are both vector data, the acceleration and the direction of the angular velocity are corrected by the orientation data of the intelligent electronic device to obtain the relative acceleration and the relative angular velocity. The relative motion attitude data can be used to guide the relative position of the user (carrier) of the somatosensory control device 10 to the intelligent electronic device 20, thereby improving the user experience and the sensitivity and accuracy of data processing. .

The above step S6 further includes:

S61. Convert the relative motion posture data into a motion recognition parameter corresponding to the motion parameter format.

S62, reading the preset action parameter and a preset action corresponding to the preset action parameter;

S63. Compare the motion recognition parameter and the preset motion parameter to obtain an action output result, and

S64. The actual action is identified according to the action output result.

Since the relative motion attitude data is information such as angular velocity, acceleration, and geomagnetic orientation, for example, in some cases, these are merely actions for reflecting a certain force in a certain direction. Therefore, the purpose of data conversion in step S61 is here. The motion recognition parameter may be a multi-dimensional array comprising a plurality of different types of motion definition criteria, such as the multi-dimensional array including direction and velocity. The motion recognition parameter has a special purpose of a specific application, and the motion recognition parameter may be different according to the purpose.

The smart electronic device 20 stores preset action command parameters and preset action or action execution criteria corresponding to the action command parameters. By comparing the motion recognition parameter and the preset motion parameter, an actual action or action standard (action output result) corresponding to the motion recognition parameter, such as a velocity size, may be obtained.

In the above step S7, the smart electronic device 20 can issue a corresponding instruction to perform a corresponding operation according to the corresponding action or action standard. The instructions may perform actions for hardware or software that invokes the smart electronic device 20, such as the smart electronic device 20 executing or displaying corresponding program instructions or actions (eg, games, fitness, rehabilitation applications), mouse, Keyboard, touch screen control. Correspondingly, the operations may be mouse operations, keyboard operations, touch screen operations, application operations, game operation displays.

The somatosensory interaction system 100 provided by the first and second embodiments of the present invention and the somatosensory interaction method implemented by the somatosensory interaction system 100, the motion posture data is sensed by the somatosensory control device 10, and the somatosensory control device is established by Correcting the motion posture data by the relative positional relationship of the intelligent electronic device 20 can avoid the use of the motion posture data due to the error caused by the orientation change or even the wrong motion recognition, thereby obtaining more accurate motion attitude sensing. The data, and thus the smart electronic device 20, can obtain a more accurate action according to the relative motion posture data, improve the accuracy of the motion recognition of the somatosensory interaction system 100, and additionally, the somatosensory is always established in the system and the interaction method. The relative position of the control device 10 and the smart electronic device 20 allows the user of the somatosensory control device 10 to operate and recognize the operation on the basis of the smart electronic device 20, thereby improving the user experience of the user.

Referring to FIG. 9, a third embodiment of the present invention further provides a somatosensory interaction method using the somatosensory interaction system 100, and the method includes the following steps:

B1, pairing the somatosensory control device 10 and the smart electronic device 20;

B2, defining an initial orientation, comprising: directing the somatosensory control device 10 to a predetermined orientation, and sensing orientation information of the somatosensory control device 10 in the predetermined orientation as initial orientation data sensed by the attitude data, and transmitting to the Intelligent electronic device 20;

B6, the smart electronic device 20 identifies an actual action according to the relative motion posture data, and

B7, the intelligent electronic device 20 issues a corresponding instruction according to the identified actual action to perform a corresponding operation.

The somatosensory interaction method of the third embodiment of the present invention is basically the same as the somatosensory interaction method of the second embodiment, except that the method performs motion recognition for the smart electronic device 20 without the orientation sensor.

In the above step B2, the setting of the initial orientation is set according to the location of the smart electronic device 20, so that the relative position of the somatosensory control device 10 and the smart electronic device 20 can be subsequently established. Preferably, the predetermined orientation is an orientation towards the smart electronic device 20. More preferably, the predetermined orientation is opposite the smart electronic device 20.

In the above step B2, the initial orientation data may be sensed according to the geomagnetic orientation sensor of the somatosensory control device 10 itself. Further, the somatosensory control device 10 converts the initial orientation data into orientation data relative to the surface.

In the above step B5, when the initial orientation is the orientation of the smart electronic device 20, the step can obtain the relative position between the somatosensory control device 10 and the smart electronic device 20, The interaction between the somatosensory control device 10 and the smart electronic device 20 provides for a better convenience and a better experience.

The steps in the third embodiment of the present invention are substantially the same as the steps in the somatosensory interaction method of the second embodiment. Specifically, the step B1 is the same as the step S1, the step B3 is the same as the step S2, and the step B4 and the step are the same. S3 is the same, and steps B6-B7 are the same as steps S6-S7. I will not repeat them here.

The somatosensory interaction method provided by the third embodiment of the present invention can prevent the simple use of the motion posture data due to the orientation change by establishing the initial orientation and correcting the motion posture data of the subsequent somatosensory control device 10 due to the motion. The error or even the wrong action recognition effectively improves the accuracy of the motion recognition of the smart electronic device 20. Further, since the relative position of the somatosensory control device 10 and the initial orientation is always established in the interaction method, the user of the somatosensory control device 10 can perform the operation and the recognition operation based on the initial orientation. Improve the user experience of the user. Finally, by establishing the initial orientation, the intelligent electronic device 20 also achieves accurate recognition of the motion without any orientation sensor, greatly expanding the selection range of the intelligent electronic device 20.

Referring to FIG. 10, a fourth embodiment of the present invention further provides an alerting method for preventing the smart electronic device 20 from being lost by using the somatosensory control device 10, including the following steps:

In the above step C1, the wireless connection pairing may be a Bluetooth connection or an infrared connection as described above. In the embodiment of the present invention, the wireless pairing connection is a Bluetooth connection. The Bluetooth and infrared generally have a certain connection pairing distance range. If the range is exceeded, the connection will be automatically disconnected. The connection predetermined distance L _{th is} a maximum distance range that can be connected between the somatosensory control device 10 and the smart electronic device 20.

In the above step C2, when the first predetermined distance L _{1 is} close to and smaller than the connection predetermined distance L _th so that the somatosensory control device 10 and the smart electronic device 20 are about to be disconnected, the somatosensory control device 10 may prompt the user that the distance from the smart electronic device 20 has exceeded the safe range, prompting the user whether to forget to carry the smart electronic device 20. The relationship between the first predetermined distance L ₁ and the connection predetermined distance L _th may preferably be: L ₁ : L _th = 6 - 9.5: 10.
