1 is a diagram schematically illustrating a network environment in which a system for linking video content and a motion chair according to an embodiment of the present invention (hereinafter, simply referred to as a 'linked system') operates.

The interlocking system of the present invention may include the interlocking server 200, and according to the embodiment, the display unit 100 and / or motion chair 300 communicating with the interlocking server 200 through the communication network 400. It may further include. The display unit 100 and the motion chair 300 can operate under the control of the linkage server 200 of the present invention.

The display unit 100 is a component that outputs video content provided through the linkage server 200 to the user, and can be implemented on various terminals. For example, the display unit 100 may be implemented on a fixed terminal or a mobile terminal implemented as a computer device. The terminal may be, for example, a TV, a smart phone, a mobile phone, a navigation device, a computer, a laptop computer, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a tablet PC, etc., but is not limited thereto. Depending on the embodiment, the terminal may be a head mounted display (HMD). The HMD is worn on the head by the user to individually view image content, and the display unit 100 may be implemented on such an HMD. The HMD includes a gyro sensor unit (not shown) capable of determining the posture of the user's head.

The display unit 100 may output video contents stored in the interworking server 200 and/or changed video contents changed by a motion control signal generated by the interlocking server 200 . For example, the video content of the present invention may be a video to which virtual reality (VR) or augmented reality (AR) is applied as content for treating mental disorders such as depression. Vulnerable classes such as the mentally ill or the elderly have a problem in that image treatment using the image contents is virtually difficult due to patient factors such as presbyopia and dizziness. Therefore, in the present invention, it is intended to provide an effective training/treatment method and system in which the motion of video contents and the motion of a motion chair are interlocked so that training/treatment using video contents can be normally performed even in the vulnerable class.

The linkage server 200 may link the video content provided through the display unit 100 and motions provided through the motion chair 300 .

Specifically, the linkage server 200 obtains movement information about movement of one area of video content provided, and provides a motion control signal for inducing a movement corresponding to the movement information to the motion chair 300 so that the movement of the motion chair is interlocked with the movement of the video content. Depending on the embodiment, the interlocking server 200 may acquire user data, generate a change control signal reflecting the user data, provide change video content according to the change, and transmit the change control signal to the motion chair 300 . As another embodiment, the interlocking server 200 obtains biometric response data of the user according to the provided reference data pair of video content and motion control signal or the variable data pair of variable video content and variable control signal, and generates a motion compensation signal reflecting the biometric response data.

The detailed configuration and operation of the interworking server 200 will be described in more detail through related drawings to be described later.

The motion chair 300 has a structure in which a user is seated and provided with motion, and can output motion by a motion control signal, a variation control signal, or a motion compensation signal provided from the linkage server 200 . At this time, the user can receive the movement of the motion chair 300 together while watching the image provided by the display unit 100 .

The communication network 400 may play a role of mediating data transmission and reception between each component of the interlocking system of the present invention. A communication method between the display unit 100, the interlocking server 200, and the motion chair 300 is not limited and may be a wired and/or wireless communication network. For example, the communication network 400 may include wired networks such as LANs (Local Area Networks), WANs (Wide Area Networks), MANs (Metropolitan Area Networks), ISDNs (Integrated Service Digital Networks), wireless LANs, CDMA, Bluetooth, and satellite communication. However, the scope of the present invention is not limited thereto.

Although the display unit 100, the motion chair 300, and the interlocking server 200 are shown as being provided in separate configurations in the drawing, they are only functionally classified according to operations performed by the interlocking system of the present invention. They do not necessarily have to be distinguished independently from each other, and may be implemented by integrating into one module if necessary. Depending on the embodiment, of course, the interlocking system may include other configurations not shown in the drawings.

2 is a block diagram showing some configurations of a configuration of an interlocking system according to an embodiment of the present invention. The apparatus 500 illustrated in FIG. 2 may have a configuration corresponding to any one of the display unit 100, the server 200, and the motion chair 300 of FIG. 1 . Such an apparatus 500 includes a memory 510, a processor 520, and a communication module 530, and may further include an input/output interface 540.

The memory 510 may temporarily or permanently store all types of data processed by each component 100, 200, or 300 having each memory. The memory may include a random access memory (RAM), a read only memory (ROM), and a permanent mass storage device such as a disk drive, but the present invention is not limited thereto.

The processor 520 may perform an operation for overall controlling each component 100, 200 or 300 having each memory 510 using various programs stored in the memory 510. The processor may include processing devices such as a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an application-specific integrated circuit (ASIC), and a field programmable gate array (FPGA), but the present invention is not limited thereto. Operations performed by each of the components 100, 200 or 300 of the system of the present invention may be performed by each processor 520 communicating with the communication module 530 of another configuration. In particular, the operation of the processor 520 of the interworking server 200 will be described in more detail in related drawings to be described later.

The communication module 530 may communicate with various types of external devices or servers according to various types of communication methods. Each communication module 530 of different devices or servers 100, 200, or 300 that may correspond to one device 500 may be connected by a network (not shown) to exchange data with each other.

The input/output interface 540 may be a means for interface with an input/output device according to each configuration. In this case, the input device may include, for example, a device such as a keyboard or a mouse for inputting user data or various sensors for measuring and obtaining user's biological response data. The output device may include a hardware device such as a display for outputting image content or a motion chair for outputting dynamic information such as motion. As another example, the input/output interface 540 may be a means for interface with a device in which functions for input and output are integrated into one, such as a touch screen.

3 is a block diagram showing the configuration of the interworking server 200 according to an embodiment of the present invention in more detail. FIG. 3 shows a processor 220 of the interlocking server 200, and this processor 220 may have a configuration corresponding to the processor 520 described above in FIG. 2 .

The processor 220 may include an image providing unit 221, a motion control signal providing unit 222, and an evaluation unit 223, and may further include a motion compensation signal providing unit 224 according to embodiments. Depending on the embodiment, the processor 220 may further include a variation control signal providing unit 22 . The modules 221 to 224 and 22 are only functionally separated and do not necessarily have to be independently separated from each other. Of course, depending on the embodiment, they may be implemented as separate devices that are physically separated from each other.

The image providing unit 221 provides image content, and may be, for example, image content for training/treatment.

The motion control signal provider 222 obtains movement information about movement of one area of the video content. Thereafter, a motion control signal for inducing a motion corresponding to the motion information may be provided to the motion chair so that the motion of the motion chair is interlocked with the motion of the video content.

The video content of the present invention may be implemented as a three-dimensional movement including movement information of at least one axis among three axis directions. In this case, the motion control signal providing unit 222 may not provide a motion control signal for the motion chair 300 when the movement information includes only first movement information in the first axis direction. For example, the first axis may be in a direction parallel to the direction of the user's field of view or posture, and when the moving direction of the video content coincides with the direction of the user's field of view or posture, a separate motion control signal may not be provided to the motion chair 300. In contrast, when the movement information of video content includes at least one of second movement information in a second axis direction crossing the first axis direction and third movement information in a third axis direction, a motion control signal corresponding to each of the second movement information and the third movement information may be provided. For example, when the movement of video content includes movement information in a direction of going up or down (up and down), left and right, or a combination thereof in the direction of the user's field of view, the motion corresponding to the movement information should be provided to the motion chair 300 to alleviate the user's motion sickness. Accordingly, motion control signals corresponding to the second and third movement information are generated and provided to the motion chair 300 so that the user can feel the 3D motion of the image content at a minimum. In generating the motion control signal, a calculation result of the evaluation unit 223 described later may be used.

The evaluation unit 223 may evaluate the motion control signal generated by the motion control signal providing unit 222 and reflect the evaluation result. The evaluation unit 223 measures the user's first reaction data according to the movement information of the video content in a state where the motion chair 300 does not move. Meanwhile, in a state where the motion control signal is applied to the motion chair 300, the user's second reaction data according to the movement information is measured. Thereafter, the motion control signal generating unit 222 may be controlled to generate a motion control signal so that the width of the second reaction data is smaller than that of the first reaction data.

According to the motion control signal generated by the above-described interaction between the motion control signal providing unit 222 and the evaluation unit 223, the user feels motion offset from the existing movement information of the video content, and can experience relief from motion sickness symptoms.

The motion compensation signal providing unit 224 obtains biological response data of the user according to the above-described video content and the reference data pair of the motion control signal, and generates a motion compensation signal reflecting this. A motion compensation signal may be generated so that the movement of the motion chair 300 is compensated by reflecting the biological response data on the motion control signal. Thereafter, subsequent video contents to which compensation corresponding to the motion compensation signal is applied to the video contents may be provided. In this case, the subsequent video content may include an image in which information about the previous motion of the video content is compensated for, and an image different from the video content.

The variation control signal providing unit 22 operates independently of the above-described motion control signal providing unit 222, and both components 222 and 22 may operate together or only one of the two components 222 and 22 may operate. The operation of the variation control signal provider 22 will be described in more detail with reference to FIG. 4 to be described later.

4 is a flowchart illustrating an interworking method according to an embodiment of the present invention. The interlocking method of the present invention may include the steps described below, and may be performed using the display unit 100, the interlocking server 200, and the motion chair 300 described above. It can be described with reference to the above-mentioned drawings together.

In step S100, the interlocking server 200 provides video contents so that the display unit 100 can output them.

In step S200, the motion control signal provider 222 of the interworking server 200 may generate a motion control signal (S201) and provide the motion control signal to the motion chair 300. At this time, movement information regarding the movement of one region of the video content may be acquired, and a motion control signal for inducing a movement corresponding to the movement information may be provided to the motion chair 300 so that the movement of the motion chair 300 may be interlocked with the movement of the video content.

In step S200, the evaluator 223 may evaluate the effect of the motion control signal and reflect it to generate the motion control signal. That is, step S201 of step S200 may include step S230 of evaluating a motion control signal. Here, step S230 will be described using FIG. 5 together. 5 is a flowchart illustrating an evaluation step according to an embodiment of the present invention.

Referring to FIG. 5 , step S230 may be performed by the evaluation unit 223 of the interlocking server 220 described above, and may include steps described below.

First, in step S231, in a state where the motion chair 300 does not move, the user's first reaction data according to the movement information of the video content is measured. Then, in step S232, in a state where the motion control signal is applied to the motion chair 300, the user's second reaction data according to the movement information is measured. Thereafter, in step S233, a motion control signal may be generated so that the width of the second reaction data is smaller than that of the first reaction data. In this way, the evaluation result is reflected in generating the motion control signal so that the motion sickness effect for the user can be minimized.

Referring back to FIG. 4 , steps S300 and S400 will be described as an operation by the variation control signal providing unit 22 of FIG. 3 described above.

In step S300, user data on a user using the video content may be obtained. The user data may include a plurality of indicators including at least one of the user's age, gender, anxiety index (eg, PANAS), and eye-related indexes (eg, eye accommodation, presbyopia, or dry eye index).

In step S400, based on the user data, it is possible to generate a variable control signal varied according to a criterion preset in the motion control signal. Step S400 includes the following steps. A dizziness correlation index is calculated based on the relationship between each of the plurality of indicators and dizziness. Thereafter, with respect to the motion control signal, the variation control signal may be generated by applying a different variation width to the motion control signal according to the value of the dizziness correlation index. In this case, the differential application of the variation range may be, for example, applying different signal strength or application period.

The dizziness correlation index of the present invention may include a first dizziness index according to at least one of age and gender. At this time, the step of generating the variation control signal (S400) may be a step of generating the variation control signal by applying the variation width as the first dizziness index increases. The first dizziness index may include, for example, an SSQ index and an FMS index as dizziness-related questionnaire scales.

Here, the generation of the variation control signal using the first dizziness index will be described using FIG. 6 together. 6 is a diagram for explaining one index for generating a motion control signal according to an embodiment of the present invention.

Referring to FIG. 6 , the horizontal axis of the table represents age group 51 and gender 52 items, and the vertical axis represents the first dizziness index D1 according to these user data items. The D1 index according to each user data item (51, 52) is examined. The larger the index value according to the D1 index, the more severe the dizziness. Looking at each age group (51, 52), it can be seen that as the age increases, each index value increases and the dizziness becomes severe.

Therefore, it is possible to provide variable video content and/or variable control signals in which dizziness is gradually alleviated (with a large fluctuation range) according to age (eg, 10-20 years old, 30 years old, 40 years old or older). That is, as the first dizziness index increases, the variation control signal may be generated by applying a variation range such as the signal strength or application period. In other words, in the case of a user suffering from severe dizziness with regard to existing video content, a variable control signal having a large variation range may be applied to provide a variable video content and/or a variable control signal in which a large amount of motion is corrected. Accordingly, even a user with severe dizziness can stably and effectively receive training/treatment services according to video content.

The dizziness correlation index of the present invention may include a second dizziness index related to a correlation between an anxiety index and an eyeball-related index, respectively, and dizziness. At this time, the step of generating the fluctuation control signal (S400) may be a step of generating the fluctuation control signal by applying the fluctuation range as the second dizziness index is smaller.

Here, the generation of the variation control signal using the second dizziness index will be described using FIG. 7 together. 7 is a diagram for explaining another index for generating a motion control signal according to an embodiment of the present invention.

Referring to FIG. 7, the horizontal axis of the table is the aforementioned first dizziness index (eg, SSQ, FMS) and the second dizziness index (D2) calculated based thereon, and the vertical axis is the anxiety index 61 and the eye-related index 62 items. As the D2 index P according to the user data items 61 and 62, the second dizziness index D2 is an index representing the correlation between the anxiety index and the eyeball-related index, respectively, and dizziness.

The anxiety index 61 may be, for example, a PANAS index related to positive emotion and negative emotion scales. The eye-related index 62 (Near point of convergence, Near point of accommodation) may be, for example, an eye-accommodative index. At this time, the smaller the D2 index value, the higher the correlation between the user data items 61 and 62 and the first dizziness indexes SSQ and FMS, meaning that dizziness is severe. In other words, the more severe the presbyopia or the more severe the dry eye syndrome, the easier it is to feel dizziness due to the provision of image content.

Accordingly, similarly, as the second dizziness index D2 is reduced, the variable image content and/or the variable control signal in which dizziness is alleviated may be provided. That is, as the second dizziness index is smaller, the variation control signal may be generated by applying a larger range of variation such as the signal strength or application period. In other words, in the case of a user suffering from severe dizziness with regard to existing video content, a variable control signal having a large variation range may be applied to provide a variable video content and/or a variable control signal in which a large amount of motion is corrected.

Hereinafter, an example of providing a variable control signal and variable video content by reflecting user data of one user will be described using FIGS. 8 and 9 . 8 and 9 are exemplary diagrams for explaining video content generated by an interworking method according to an embodiment of the present invention.

Referring to FIG. 8 , video content provided to a user by the video providing unit 210 is illustrated. An output image 71 at one point in time and an output image 72 at a later point in time are shown to indicate the movement of video content. In each of the output images 71 and 72, coordinate information for identifying a specific point may be indexed. Point P1 of the 71 image and point P2 of the 72 image are indexed with the same type of coordinate information, so the processor 220 can recognize the points P1 and P2 of the two viewpoints as the same point. At this time, the processor 220 may calculate the change speed of each of the coordinate information P1 and P2, and calculate first speed information as movement speed information of a specific point of the image content based on the change speed.

Referring to FIG. 9 , video content according to FIG. 8 and variable video content reflecting user data receiving a training service according to a corresponding motion control signal are shown. Similarly, an output image 81 at one point in time and an output image 82 at a point in time after the point in time are shown to indicate the movement of the variable image content. In each of the output images 81 and 82, coordinate information for identifying a specific point may be indexed for each specific point. Point P1 of the 81 image and point P3 of the 82 image are indexed with the same type of coordinate information, so the processor 220 can recognize the points P1 and P3 of the two viewpoints as the same point. At this time, the processor 220 generates the variable video content so that the 82 video is output as the second speed information whose value is changed compared to the aforementioned first speed information.

Depending on the dizziness index value calculated based on the user data of one user, a variable control signal may be generated by applying a larger variation range to a patient with severe dizziness. For example, in FIGS. 8 and 9, when the patient is evaluated as having severe dizziness (e.g., as the value of D1 increases or the value of D2 decreases), the movement speed from P1 to P3 in FIG. 9 is more reduced than the movement speed from P1 to P2 in FIG.

In the above, it has been described as an example of step S400, but the provision of video contents according to FIGS. 8 and 9 can also be applied to the provision of motion compensation signals and/or subsequent video contents corresponding thereto by the motion compensation signal provider 224 described above according to the same principle.

Embodiments according to the present invention described above may be implemented in the form of a computer program that can be executed on a computer through various components, and such a computer program may be recorded on a computer-readable medium. In this case, the medium may store a program executable by a computer. Examples of media may include magnetic media such as hard disks, floppy disks and magnetic tapes, optical recording media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, and those configured to store program instructions, including ROM, RAM, flash memory, and the like.
