Description

TECHNICAL FIELD The present invention relates to a method for determining a motion intention of a user and a motion recognition system for the same,

In recent years, wearable devices that are worn on the wearer's body (head, arm, etc.) have been increasingly used in various fields, for example, by recognizing the motion of the user and using the motion recognition interface for controlling the wearable device itself or controlling other electronic devices .

However, in the case of a keyboard, a mouse, a joystick, etc., it is rare that the user operates only when the user intends to use the device, and does not operate when the user does not intend to use the device.

However, since the motion recognition device using the motion sensor or the camera can recognize all the operations of the user, there is a problem that the user can recognize and process unintentional motion that is not intended by the user.

For example, even if a user performs a game using the motion recognition device and the user touches or scratches his / her head unintentionally regardless of the game motion, the motion recognition device recognizes the motion as a movement instruction of the virtual object displayed on the game screen, Can be moved in the wrong direction that the user does not intend.

Therefore, the motion recognition apparatus accurately determines whether the recognized motion is a motion intended by the user or an unintended motion, and generates an operation signal corresponding only to the motion intended by the user, thereby enhancing the reliability of the motion detection apparatus, You need to minimize it.

1st Example

A first embodiment of the present invention relates to a method of recognizing a user's operation using a motion sensor and an electromyography sensor.

The system to which the motion recognizing method according to the first embodiment is applied includes an operation detecting device 100 for detecting an operation of a user as shown in the configuration of FIG. 1 and a block diagram of FIG. 2, A detection device 200, and a control target device 300 that receives a signal from the motion detection device 100. [

The motion detection device 100 includes a motion sensor 110 and a communication means 130 as a device for the user to hold or wear.

The motion sensor 110 is a sensor for sensing movement of a user carrying or wearing the motion detection device 100. The motion sensor 110 may be a three-axis accelerometer, a three-axis angular velocity sensor, a geomagnetic sensor, . ≪ / RTI >

The motion sensor 110 may include signal processing means for generating an operation signal to be transmitted to the control target device 300 by amplifying and filtering the detection signal. The operation signal may include information on the operation direction, speed, acceleration, and the like.

The electromyographic detection apparatus 200 includes at least one electromyographic sensor 210 for detecting an electromyographic (EMG) signal generated on the surface of a user's muscle and a detected electromyogram signal to the controlled device 300 And communication means (230). The electromyogram sensor 210 may include signal processing means for amplifying and filtering the detection signal.

Each of the communication means 130 and 230 performs wireless communication between the control devices 300. The wireless communication method is not particularly limited and may be a wireless communication method such as Bluetooth, Zigbee, infrared data communication (IrDA), UWB (Ultra Wide Band), NFC (Near Field Communication), WiFi Lt; / RTI >

The reason for using the electromyographic detection apparatus 200 in the first embodiment of the present invention is to accurately determine the operation intention of the user using the motion detection apparatus 100. [

For example, when the user moves the motion detecting device 100 with the intention of controlling the controlled device 300 while holding the motion detecting device 100 in his / her hand, he / she consciously or unconsciously hands the force The electromyogram signal related to the finger motion can be detected through the electromyogram detecting device 200. [

On the other hand, when the user moves the motion detecting device 100 without intention of controlling the controlled device 300 while holding the motion detecting device 100 in his / her hand, the electromyogram detecting device 200 detects the electromyogram The signal is not detected or is detected very weakly.

Accordingly, by using this difference, it can be determined whether the operation of the user who moves the motion detection apparatus 100 is an intentional operation or an unconscious operation.

1, the electromyography detecting apparatus 200 is shown as a wrist-wearing type, but the present invention is not limited thereto. For example, in the case of controlling the control subject device 300 using the motion of the leg, the user can wear the motion detection device 100 on the leg. In this case, in order to detect the EMG signal according to the motion of the leg It is preferable to wear the electromyogram detecting device 200 on the user's calf or ankle.

That is, the mounting position of the electromyography detecting apparatus 200 may vary depending on the body part of the user operating the motion detecting device 100.

The control target device 300 may include a communication unit 310, an operation determination unit 320, a control signal generation unit 330, a display 340, a driving unit 350, and the like.

The communication means 310 communicates with each of the communication means 130 and 230 of the motion detection device 100 and the electromyographic detection device 200 according to a set communication method.

The operation determination means 320 determines whether the operation signal received from the operation detection apparatus 100 is caused by an operation intended by the user or by an unintentional unconscious operation by using the EMG signal.

Specifically, when the characteristics (pattern, intensity, etc.) of the electromyogram signal received from the electromyogram detecting apparatus 200 satisfy the set criteria, it is determined that the operation signal received from the motion detecting device 100 is due to the operation intended by the user do. It is needless to say that it is necessary to previously store the information such as the reference pattern and the reference intensity for comparing with the received EMG signal in the control target device 300 in advance.

If the electromyogram signal is not received or the characteristics of the received electromyogram signal does not satisfy the set criterion, it is determined that the operation signal received from the motion detection device 100 is due to an operation that the user does not intend.

When it is determined that the operation signal received from the operation detecting device 100 is caused by the user's intended operation, the control signal generating means 330 controls the operation of the control target device 300 using the operation signal As shown in Fig.

The control signal may include various types of information depending on the specific object to be controlled.

For example, when the object displayed on the display 340 is the object to be controlled, the control signal may include information about the position, movement direction, movement speed, acceleration, rotation direction, and rotational angular velocity of the object.

As another example, when the driving means 350 such as an actuator that operates all or a part of the control target device 300 is the object to be controlled, it may include information necessary for the operation of the driving means 350. [

Hereinafter, a method for determining the user's operation in the motion recognition system according to the first embodiment of the present invention will be described with reference to the flowchart of FIG.

First, it is assumed that the user grasps and uses the motion detection device 100 with the motion sensor 110 as shown in FIG. In this case, it is preferable that the electromyogram detection device 200 is worn on the user's wrist as described above.

In this state, when the user performs an arbitrary operation, the motion detection device 100 sends out the motion signal generated by the motion sensor 110, and when the communication means 310 of the control subject device 300 receives the motion signal (ST11)

The operation determination unit 320 of the control target device 300 determines whether an EMG signal is received from the EMG detection device 200. If the EMG signal is not received, It is determined that the operation is not performed and the corresponding operation signal is ignored. (ST12)

If the EMG signal is received, it is determined whether or not the characteristic (pattern, intensity, etc.) of the EMG signal is compared with the stored characteristic to meet the setting criterion, and if the setting criterion is not satisfied, the corresponding operating signal is ignored. (ST13)

If the received electromyogram signal satisfies the setting criterion, the operation determination means 320 determines that the received operation signal is due to the operation intended by the user, and in response, the control signal generation means 330 receives And controls the operation of the control target device (300) by generating a control signal based on the received operation signal. (ST14)

On the other hand, in step ST12, it is necessary to set in advance a criterion to be processed by the control subject device 300 when the operation signal and the EMG signal are received at different points in time. When the operation signal and the EMG signal are received with a time lag which is too large, it is difficult to accurately determine the user's operation intention using the EMG signal.

For example, the following criteria can be selectively set. First, if the operation signal and the EMG signal are received at the same time, it is determined that the EMG signal has been received and step ST13 can be performed. Second, when the operation signal is received first, it is determined that the EMG signal has been received within the set time from the reception time of the operation signal, and the ST13 step can be performed. Thirdly, when the EMG signal is received first, it is determined that the EMG signal has been received only within a predetermined time from the reception of the EMG signal, and the ST13 step can be performed. However, these criteria are examples only, so other criteria may apply.

It is also necessary to set a criterion for determining at what point the control operation is terminated after the control of the control target device 300 is started by the user's intended operation.

As an example, the control subject device 300 may perform a control operation while receiving the EMG signal, and may set the control operation to be terminated if the EMG signal is not received.

As another example, when the control subject device 300 receives the electromyogram signal of a specific pattern, the control subject device 300 can perform a control operation for a set period and end the control operation when the period elapses.

As another example, when the control subject device 300 receives the electromyogram signal of a specific pattern, it is possible to terminate the control operation for a set period and automatically perform the control operation when the period elapses.

As another example, when the control subject device 300 receives the EMG signal of the first pattern, the control operation proceeds, and when the EMG signal of the second pattern is received, the control operation can be terminated.

Second Example

The first embodiment of the present invention is based on the premise that the operation detecting device 100 having the motion sensor 110 and the electromyography detecting device 200 having the electromyogram sensor 210 are separate devices.

However, the motion sensor and the electromyogram sensor can be included in one apparatus, and the second embodiment of the present invention relates to a method of recognizing an operation using such a system.

As shown in the configuration of FIG. 4 and the block diagram of FIG. 5, the system to which the motion recognition method according to the second embodiment of the present invention is applied includes a wearable device 500 for detecting a user's motion and an electromyogram, And a control target device 300 that receives a signal of the apparatus 500. [

The wearable device 500 is a device that generates a predetermined control signal while the wearer wears the body. Although the figure is shown as being worn on the wrist, it is not particularly limited and may be worn on other parts of the body such as the forearm, leg, ankle, waist, neck, head and the like of the user.

The wearable device 500 may include a motion sensor 510, an electromyogram sensor 520, an operation intention determining means 530, a storage means 540, a communication means 550, and the like.

The configuration and functions of the motion sensor 510 and the electromyogram sensor 520 are the same as those of the first embodiment, and thus description thereof is omitted. The electromyogram sensor 520 is preferably exposed to the inner surface of the wearable device 500 so as to be in contact with the user's skin.

The operation intention determining means 530 uses the electromyogram signal detected by the electromyogram sensor 520 to determine whether the operation signal detected by the motion sensor 510 is caused by an operation intended by the user or an unintentional unconscious operation Or not. Since the specific function is the same as the operation determination means 320 of the control target device 300 in the first embodiment, the description is omitted.

In the second embodiment of the present invention, the operation determination means 530 is provided in the wearable device 500, and thus the wearable device 500 does not need to transmit the EMG signal to the control target device 300 , It is possible to increase the signal processing speed of the control subject device 300 since only the operation signal intended by the user is transmitted to the control subject device 300. [

However, the present invention is not necessarily limited to this, and thus the operation-intention determining means 530 in the wearable apparatus 500 may be omitted. In this case, the wearable device 500 must transmit both the operation signal detected by the motion sensor 510 and the electromyogram signal detected by the electromyogram sensor 520 to the control target device 300, It may be determined whether or not the operation is performed.

In addition, since the wearable device 500 according to the second embodiment of the present invention does not require the user to grip the motion detection device, it is possible to generate various patterns of EMG signals using the user's finger, There is an advantage that the operation of the control subject device 300 can be controlled in a more various manner.

The control target device 300 may include a communication means 310, a control signal generating means 330, a display 340, a driving means 350, and the like.

The control signal generating means 330 generates a control signal for controlling the operation of the control target device 300 by using the operation signal received from the wearable device 500. If the control target device 300 includes the operation determination means, the control signal generation means 330 generates the control signal only when the received operation signal is determined to be the result of the intended operation of the user.

The communication means 310, the display 340, the driving means 350, and the like are the same as those described in the first embodiment.

Hereinafter, a method for determining the user's operation in the motion recognition system according to the second embodiment of the present invention will be described with reference to the flowchart of FIG.

4, it is assumed that the user wears a wearable device 500 having a motion sensor 510 and an EMG sensor 520 on his / her wrist.

In this state, when the user performs an arbitrary operation, the motion sensor 510 detects the user's operation and generates an operation signal. (ST21)

When an operation signal is generated in the motion sensor 510, the operation determination means 530 checks whether the electromyogram signal is detected in the electromyogram sensor 520. If the electromyogram signal is not detected, Determines that the operation signal detected by the user is due to an operation that is not intended by the user, and ignores the operation signal. (ST22)

In the above step, when the EMG signal is detected, the operation intention determining means 530 judges whether or not the characteristic (pattern, intensity, etc.) of the EMG signal satisfies the setting criterion in comparison with the stored characteristic, If it is not satisfied, the operation signal is ignored. (ST23)

If the detected electromyogram signal satisfies the setting criterion, the operation determination means 530 determines that the operation signal detected by the motion sensor 510 is due to the operation intended by the user. Subsequently, the control means (not shown) transmits the operation signal detected through the communication means 540 to the control target device 300. (ST24)

Then, the control signal generating means 330 of the control target device 300 generates a control signal based on the received operation signal and controls the operation of the control target device 300. [ (ST25)

In the second embodiment of the present invention, similarly to the first embodiment, when the operation signal and the EMG signal are detected at different points in time, the reference to be processed by the wearable device 500 needs to be set in advance.

For example, the following criteria can be selectively set. First, if the operation signal and the EMG signal are detected at the same time, it is determined that the EMG signal is detected and the ST23 step can be performed. Secondly, when the operation signal is detected first, it is determined that the electromyogram signal is detected within the set time from the detection time of the operation signal, and the step ST23 can be performed. Thirdly, if the EMG signal is detected first, it is determined that the EMG signal has been detected within a predetermined time from the detection time of the EMG signal, and step ST23 can be performed. However, since these criteria are merely examples, other criteria may be applied as described above.

Third Example

A third embodiment of the present invention relates to a method of recognizing a user's operation using an operation detecting camera and an EMG sensor.

7, the system to which the motion recognizing method according to the third embodiment is applied includes an operation detecting camera 600 for detecting an operation of a user, an electromyographic detection device 200 mounted on a user's body, And a control target device 300 controlled in accordance with an operation signal detected by the motion detection camera 600.

The motion detection camera 600 may be installed in the control target device 300 or may be installed in a set-top box connected to the control target device 300 as shown in the figure, and detects information about a user's body motion.

The electromyographic detection device 200 and the control subject device 300 are as described in the first embodiment.

Hereinafter, a method for determining the user's operation in the motion recognition system according to the third embodiment of the present invention will be described with reference to the flowchart of FIG.

First, the user is positioned in front of the motion detection camera 600 while wearing the electromyogram detection device 200.

In this state, when the user performs an arbitrary operation, the motion detection camera 600 generates and transmits an operation signal corresponding to the motion of the user to the control subject device 300. In the control subject device 300, (ST31)

The operation determination unit 320 of the control target device 300 determines whether or not an EMG signal is received from the EMG detection device 200. If the EMG signal is not received, One operation signal is determined to be due to an operation that is not intended by the user, and the operation signal is ignored. (ST32)

In the above step, when the EMG signal is received, it is determined whether or not the characteristics (pattern, intensity, etc.) of the EMG signal are compared with the stored characteristics to determine whether or not the EMG signal satisfies the setting reference. . (ST33)

If the received electromyogram signal satisfies the setting criterion, the operation determination means 320 determines that the received operation signal is due to the operation intended by the user, and in response, the control signal generation means 330 receives And controls the operation of the control target device (300) by generating a control signal based on the received operation signal. (ST34)

On the other hand, in step ST32, when the operation signal of the motion detection camera 600 and the EMG signal are received at different times, the control target device 300 can be processed by applying the criteria described in the first embodiment.

Fourth Example

The system to which the motion recognition method according to the fourth embodiment of the present invention is applied includes an operation detection device 100a for detecting an operation of a user and sending out an operation signal as shown in the configuration of Fig. 9 and the block diagram of Fig. 10, And a control target device 300 that receives an operation signal.

The operation recognition system according to the fourth embodiment of the present invention differs from the first to third embodiments in that an electromyogram sensor is not used.

The motion detection device 100a includes a motion sensor 110, an intention detection means 120, a communication means 130, a storage means 140, an operation determination means 150, And the like.

The intention detecting means 120 is for detecting the intention of the user, and may be an input means such as a button, a switch, a touch key or the like exposed to the outside of the motion detecting device 100a, It may be a pressure sensor.

The operation intention determining unit 150 determines whether the operation signal detected by the motion sensor 110 is based on the user's intention using the signal input through the intention detecting unit 120.

Hereinafter, a method for determining the user's operation in the motion recognition system according to the fourth embodiment of the present invention will be described with reference to the flowchart of FIG.

First, it is assumed that the user grasps and uses the motion detection device 100a in which the motion sensor 110 is embedded, as shown in FIG.

In this state, when the user performs an arbitrary operation, the motion sensor 110 detects a user operation and generates an operation signal. (ST41)

When an operation signal is generated in the motion sensor 110, the operation intention determining means 150 determines whether a predetermined signal is detected through the intention detecting means 120. If the input signal is not detected, It determines that the operation signal is due to an operation that the user does not intend and ignores the operation signal. (ST42)

If a predetermined input signal is detected through the intention detecting means 120, the operation intention determining means 150 determines that the operation signal detected by the motion sensor 110 is due to an operation intended by the user. Subsequently, the control means (not shown) transmits the operation signal detected through the communication means 130 to the control target device 300. (ST43)

Then, the control signal generating means 330 of the control target device 300 generates a control signal based on the received operation signal and controls the operation of the control target device 300. [ (ST44)

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments.

For example, in the above-described embodiment, the operation signal of the user is detected using the motion sensor 110 or the motion detection camera 600, and the control target device 300 is controlled. However, In a case where the operation mode is various, it may be difficult to select all of the various operation modes by only the operation signal detected by the motion sensor 110 or the motion detection camera 600. [

In this case, the characteristics (pattern, intensity, and the like) of various EMG signals corresponding to the various operation modes are stored in advance and the user's intention of the operation is determined using the detected EMG signal pattern or intensity, It is also possible to set the operation mode to be determined.

As another example, in the first to third embodiments of the present invention, the degree of operation is determined using the user's EMG. However, depending on the specific application field, other types of biological signals, for example, brain waves EOG), electrocardiogram (EOG), eye conduction (EOG), body temperature, blood pressure, pulse, and the like.

Specifically, when a head mount device is used, movement of muscles around the eye can be confirmed by using an EOG sensor, and movement of the pupil can be confirmed using an eye movement monitoring sensor such as a camera. In addition, EEG can be easily detected using an EEG sensor. Therefore, the operation signal detected by the motion sensor can be transmitted to the control target device only when the setting criterion is met in comparison with the setting criterion, such as the strength or pattern of the safety degree, the motion or flicker of the pupil, the intensity or pattern of the brain waves, .

Meanwhile, the type of the control target device 300 is not particularly limited. For example, the control target device 300 may be a personal computer such as a computer and its peripheral devices, a game device, a virtual reality (VR) device, an augmented reality (AR) device, Home appliances, electronic door locks, vehicle mounted devices, medical devices, industrial robots, and medical robots, which are used in home appliances such as air conditioners, audio, video, refrigerators, washing machines and vacuum cleaners, heating devices, lighting devices, communication devices, .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventive concept as defined by the appended claims. I will do it.
