Description

[Technical field]

[0001] The present invention relates to a virtual reality-based eye movement and visual perception training providing device and method, and more particularly to a virtual reality-based eye movement and visual perception training providing device and method that enables training to improve eye movement ability and visual perception ability including stereoscopic sensation based on virtual reality. [Background technology]

[0002] In recent years, with the development of media, the incidence of myopia, astigmatism, strabismus, etc. has increased. Although there are many studies on the treatment of these diseases, there is still a lack of research on the factors that affect the development of normal vision.

[0003] Strabismus is a condition in which the eyes do not line up. If not treated early, there is a risk of vision being lost forever, so it must be detected and corrected early in childhood.

[0004] If strabismus appears around the age of 2-5, the child's eyes will see different objects, and as a result, two completely different images will be transmitted to the brain, causing visual confusion in which completely different objects are seen in double. In addition, because the child experiences the phenomenon of double vision, in which one image appears to be in two different places at the same time, the child will ignore the image coming from one side in order to resolve the visual confusion and double vision. As a result, the child will abandon the function of binocular vision that allows the child to perceive objects in three dimensions, and will eventually give up using the affected eye, leading to amblyopia.

[0005] If these symptoms are left untreated, the child will become an adult and will be unable to correct their vision even with the use of glasses or lenses or through surgery, and will end up seeing with only one eye and losing the sense of three-dimensional distance. Therefore, when strabismus appears in children, it is important to diagnose it early and treat it appropriately for the sake of their vision and quality of life.

[0006] However, if the angle of strabismus is small or the fusion ability is good, eyeglass treatment or orthoptic training can be performed, but there are problems in that the treatment takes a long time and is costly.

[0007] Therefore, there is a need to develop technology that provides and controls eye movement and visual perception training based on virtual reality in order to improve the user's (subject's) eye movement ability and visual perception ability, including stereoscopic sensation. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has been made in consideration of the above circumstances, and its object is to provide an apparatus and method for providing virtual reality-based eye movement and visual perception training that takes into account the deviation of the user's eyes and provides a dichoptic presentation, thereby preventing further damage to stereoscopic vision due to suppression.

[0009] Another object of the present invention is to provide a virtual reality-based eye movement and visual perception training device and method that allows a user to receive training suited to his or her own condition by adjusting the difficulty level by changing the position of visual stimuli based on the user's deviation level and training ability, as well as to simultaneously train eye movement (movement) and visual perception, including stereoscopic perception.

[0012] Meanwhile, a method for providing virtual reality-based eye movement and visual perception training according to an embodiment of the present invention includes a step of outputting a first image and a second image including a visual stimulus (dichoptic presentation) for inducing binocular disparity to each of a plurality of first displays and a plurality of second displays provided in the device, the first display and the second display being respectively disposed at positions corresponding to the eyes of a test subject, a step of receiving a response of the test subject to the visual stimulus, a step of acquiring visual information regarding the test subject based on the response, and a step of controlling the training provided to the test subject by changing only the visual stimulus of the image output corresponding to the eyeball having strabismus among the first image and the second image based on the acquired visual information, the visual information including information regarding the presence or absence of strabismus regarding the left and right eyes of the test subject, and a strabismus angle and stereoscopic information which are information regarding the degree of strabismus.

[0024] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. A subject referred to in the following description refers to a user who performs eye movement and visual perception training using a virtual reality-based eye movement and visual perception training providing device according to an embodiment of the present invention.

[0025] FIG. 1 is a diagram explaining the concept of strabismus and training for improving the visual ability and stereoscopic perception of the eyes.

[0026] Strabismus is a visual disorder in which the eyes do not line up and look at different points. When one eye looks straight ahead, the other eye looks inward or outward, or up or down. Strabismus can be constant, but it can also occur intermittently, with the eyes shifting to stare straight ahead at one moment, or shifting from staring straight ahead to staring intermittently.

[0027] Figure 1 shows an example in which the subject's right eye has exotropia. When the subject looks straight ahead, the left eye faces straight ahead, while the right eye faces outward.

[0028] In order to improve the visual and stereoscopic abilities of the eyes of such a subject, the subject must repeatedly undergo training to focus the right eye inward, i.e., toward the center.

[0029] The present invention provides such eye movement and visual perception training based on virtual reality.

[0030] FIG. 2 is a block diagram showing a configuration of a virtual reality-based eye movement and visual perception training providing device according to an embodiment of the present invention.

[0031] Referring to FIG. 2, a virtual reality-based eye movement and visual perception training provision device (hereinafter referred to as the "training provision device") 100 according to an embodiment of the present invention includes a communication module 110, an input module 130, a display module 150, a memory 170 and a control module 190.

[0032] The communication module 110 performs wired or wireless communication with at least one external device (such as a server) and transmits and receives wireless signals through a communication network based on wireless Internet technology.

[0033] Examples of wireless Internet technologies include WLAN (Wireless LAN), Wi-Fi (registered trademark) (Wireless-Fidelity), Wi-Fi (Wireless Fidelity) Direct, DLNA (registered trademark) (Digital Living Network Alliance), WiBro (Wireless Broadband), WiMAX (registered trademark) (World Interoperability for Microwave Access), HSDPA (High Speed ​​Downlink Packet Access), HSUPA (High Speed ​​Uplink Packet Access), LTE (Long Term Evolution), LTE-A (Long Term Evolution-Advanced), and the training provision device 100 will send and receive data using at least one of the wireless Internet technologies, including Internet technologies not listed above.

[0034] The short-range communication may be supported using at least one of Bluetooth (registered trademark), RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee (registered trademark), NFC (Near Field Communication), Wi-Fi (registered trademark), Wi-Fi Direct, and Wireless Universal Serial Bus (Wireless USB) technologies. In this case, the short-range wireless communication network may be a Wireless Personal Area Network.

[0035] The input module 130 can acquire signals corresponding to inputs from the subject, such as inputs from the subject for performing measurements or training, responses to visual stimuli provided via the display module 150, etc.

[0036] In this case, the input module 130 may include a keyboard, a keypad, a button, a jog shuttle, a wheel, etc. Also, the input of the test subject in the input module 130 may be, for example, a button press, a touch, a drag, etc.

[0037] The input module 130 may be configured as a separate module connected wirelessly or by wire to the training providing device 100. For example, the training providing device 100 may provide the subject with an image for performing measurement or training via the display module 150 mounted and attached to the subject's head, and may receive a response from the subject via the input module 130, which is a separate module attached to the subject's hand.

[0038] The display module 150 outputs a video or image. For example, the display module 150 may include an LCD, an OLED, an AMOLED, etc.

[0039] The display module 150 may include a plurality of first and second displays corresponding to the eyes (left and right eyes) of the subject, respectively. Here, the first display may output a first image, and the second display may output a second image. At this time, the first and second images are for expressing a visual stimulus (dichoptic presentation) for inducing binocular disparity, and may be any one of the same image, images that at least partially overlap each other, and images that do not overlap each other. Here, the visual stimulus is a frame and a sinusoidal grating visual stimulus having a certain shape, and includes a reference stimulus and a target stimulus.

[0040] Here, the display module 150 may include a first display and a second display that are physically separated from each other, or may be configured to be divided into a left region and a right region of a single display.

[0041] The memory 170 stores various data (information) as well as at least one data (information) and at least one process required for providing virtual reality-based eye movement and visual perception training. For example, the memory 170 may store a program for performing training, at least one piece of subject information (personal information, visual information, response information, training results, etc.), various reference values ​​that serve as a basis for measuring the strabismus angle and / or stereoscopic effect, measurement images, training images, etc. In addition, the memory 170 stores various commands, algorithms, etc. for performing the virtual reality-based eye movement and visual perception training providing method.

[0042] Also, the memory 170 may include at least one type of storage medium among flash memory type, hard disk type, multimedia card micro type, card type memory (e.g., SD or XD memory, etc.), Random Access Memory (RAM), Static Random Access Memory (SRAM), Read-Only Memory (ROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), Programmable Read-Only Memory (PROM), magnetic memory, magnetic disk, and optical disk. Also, the memory 170 may store information temporarily, permanently, or semi-permanently, and may be provided as a built-in or removable type.

[0043] The control module 190 controls the configuration within the training providing device 100 or processes and calculates various information, and controls the virtual reality-based eye movement and visual perception training to be performed based on at least one process stored in the memory 170.

[0044] The control module 190 outputs a first image and a second image expressing a visual stimulus (dichoptic presentation) for inducing binocular disparity to the first display and the second display, respectively, and acquires visual information on the subject based on the subject's response to the visual stimulus received via the input module 130. Then, the control module 190 controls so that training is performed by changing only the visual stimulus of the image outputted corresponding to the eyeball having strabismus among the first image and the second image based on the acquired visual information. At this time, the first image and the second image express the same visual stimulus, and the image outputted corresponding to the eyeball having strabismus has a visual deviation according to the acquired visual information.

[0045] That is, the control module 190 outputs a first image and a second image expressing visual stimulation to the left and right eyes of the subject, respectively, and controls so that the image output corresponding to the eyeball without strabismus is left as is and only the image output corresponding to the eyeball with strabismus is changed to train the movement of the eyeball. That is, the eyeball with strabismus is trained to focus in a specific direction.

[0046] Meanwhile, the visual information may include at least one of information on the presence or absence of strabismus regarding the left and right eyes of the subject, and information on the angle of strabismus and stereoscopic effect, which are information on the degree of strabismus.

[0047] The control module 190 can measure the strabismus angle of the test subject by inducing the respective visual stimuli included in the first image and the second image to be combined into one image and measuring the moving distance of the test subject's gaze. In addition, the control module 190 can measure the three-dimensional effect of the test subject by receiving a response to a stimulus that gives a three-dimensional effect from among the first display and the second display with respect to the visual stimulus, and receiving a response as to whether the three-dimensional effect direction is concave or convex with respect to the stimulus that gives a three-dimensional effect.

[0048] The control module 190 can be realized by software, hardware, or a combination thereof. For example, the control module 190 can be realized by hardware such as a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), a semiconductor chip, or other various types of electronic circuits. For example, the control module 190 can be realized by software such as a logic program executed by the above-mentioned hardware, various computer languages, etc.

[0049] In the following description, unless otherwise specified, it can be understood that the operation of the training providing device 100 is performed under the control of the control module 190.

[0050] The training providing device 100 according to an embodiment of the present invention may include various devices capable of performing computational processing. For example, the training providing device 100 may include a desktop PC, a mobile phone, a smart phone, a laptop computer, a personal digital assistant (PDA), a portable multimedia player (PMP), a slate PC, a tablet PC, an ultrabook, a wearable device, and the like.

[0051] Meanwhile, the training provision device 100 may include a head-mounted device such as an HMD (Head Mounted Display) that is worn on the subject's head to display images, smart glasses, smart goggles, or a display device such as a mobile phone that can be attached to a head-mounted device and used.

[0052] Meanwhile, the training providing device 100 shown in Fig. 2 is merely one embodiment and is not limited thereto. For example, when the display module 150 is realized as a touch screen, the display module 150 may also function as the input module 130. In this case, a separate input module 130 may not be provided or an input module 130 having limited functions such as a volume control, a power button, and a home button may be provided according to a selection. Also, the display module 150 may be provided in the form of a video output port that transmits video information to an external display device.

[0053] Fig. 3 is a diagram showing an example of an image outputted through a display module of the virtual reality-based eye movement and visual perception training providing device according to an embodiment of the present invention, showing a case where a test subject having exotropia in the right eye is controlled to perform training. Fig. 3 also shows a display module that can be seen when the test subject wears the training providing device 100, and includes a first display 151 arranged in an area corresponding to the test subject's left eyeball and a second display 152 arranged in an area corresponding to the test subject's right eyeball.

[0054] As described above, the visual stimuli include a reference stimulus and a target stimulus, and the visual stimulus included in the image outputted corresponding to the eyeball having strabismus among the first image and the second image is arranged at a position determined based on the strabismus angle in the corresponding image, and is provided such that there is a difference between the central axis of the reference stimulus and the central axis of the target stimulus in the corresponding image. Meanwhile, the visual stimulus included in the image outputted corresponding to the eyeball having no strabismus among the first image and the second image is arranged based on the center of the corresponding image, and is provided such that the central axis of the reference stimulus and the central axis of the target stimulus are arranged on the same line in the corresponding image.

[0055] Referring to FIG. 3, a first image 10 is output through a first display 151 corresponding to an eyeball that does not have strabismus, and a second image 20 is output through a second display 152 corresponding to an eyeball that has strabismus.

[0056] At this time, the first image 10 and the second image 20 both display visual stimuli, but include a heart-shaped object as a reference stimulus and a star-shaped object as a target stimulus. However, the first image 10 corresponding to the left eye, which does not have strabismus, has the visual stimulus placed in the center of the image, whereas the second image 20 corresponding to the right eye, which has strabismus, has the visual stimulus placed in a position reflected based on the strabismus angle of the subject. In addition, the central axis C (which coincides with the central axis of the first image 10) of the first reference stimulus 11 displayed in the first image 10 and the central axis D of the first target stimulus 12 are arranged on the same line, whereas the central axis C of the second reference stimulus 21 and the central axis D of the second target stimulus 22 displayed in the second image 20 are arranged to have a difference.

[0057] Meanwhile, when the training providing device 100 provides eye movement and visual perception training for the test subject, the central axis D of the second target stimulus 22 may be gradually moved toward the central axis C of the second reference stimulus 21 by a preset distance over a preset time period so that the test subject may perform training. Here, the preset distance and the preset time period are set based on visual information regarding the test subject, and may be changed and set according to the training ability or need of the test subject.

[0058] FIG. 4 is a diagram showing an example of a third image in which visual stimuli from the first and second images are combined, induced by a virtual reality-based eye movement and visual perception training providing device according to an embodiment of the present invention.

[0059] 3, the subject is induced to combine two visual stimuli into one image by simultaneously providing the first image 10 and the second image 20 through the first display 151 and the second display 152, respectively, so that the subject can see a visual stimulus such as the third image 30. As a result, the subject cannot sense a three-dimensional effect through the third target stimulus 32, but can sense a three-dimensional effect through the third reference stimulus 31.

[0060] FIG. 5 is a flow chart illustrating a method for providing virtual reality-based eye movement and visual perception training according to an embodiment of the present invention.

[0061] A first image and a second image including a visual stimulus (dichoptic presentation) for inducing binocular disparity are output to each of a plurality of first displays and a plurality of second displays provided in the training provision device 100, and provided to the subject (S210), and a response to the visual stimulus is received from the subject (S230).

[0062] Based on the response, visual information about the subject is acquired (S250), and based on the acquired visual information, only the visual stimuli of the first and second images output corresponding to the eyeball with strabismus are changed to control the training provided to the subject (S270).

[0063] Specifically, when controlling the training, the central axis of the target stimulus, which is one of the reference stimulus and target stimulus contained in the image output corresponding to the eyeball with strabismus, is moved toward the reference stimulus, thereby controlling the subject to train the corresponding eyeball.

[0064] FIG. 6 is a flowchart showing a process of measuring a stereoscopic effect among visual information related to a test subject in order to provide virtual reality-based eye movement and visual perception training according to an embodiment of the present invention.

[0065] 5, the training providing device 100 can obtain the strabismus angle and stereoscopic information as the visual information of the test subject through the visual information obtaining step, in which the stereoscopic information can be obtained based on the test subject's response.

[0066] Specifically, a response to the stimulus from which a three-dimensional effect is felt from the first display or the second display is received from the test subject (S251), and a response as to whether the three-dimensional effect is concave or convex with respect to the stimulus from which a three-dimensional effect is felt is received (S253). In this way, the training providing device 100 can measure the three-dimensional effect of the test subject.

[0067] The steps of a method or algorithm described in connection with the embodiments of the present invention may be implemented directly in hardware, in software modules executed by hardware, or in a combination thereof. The software modules may be present in a Random Access Memory (RAM), Read Only Memory (ROM), Erasable Programmable ROM (EPROM), Electrically Erasable Programmable ROM (EEPROM), Flash Memory, a hard disk, a removable disk, a CD-ROM, or any other form of computer readable storage medium known in the art to which the present invention pertains.

[0068] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art will understand that the present invention can be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, the above-described embodiments should be understood as illustrative and not restrictive in all respects.
