Description

Technical Field

[0001] The present invention relates to an apparatus for providing perspective visual perception training using virtual reality and visual stimuli, and a method of operating the apparatus.

Background Art

[0002] In recent years, with the development of media, the incidence of myopia, astigmatism, strabismus, etc. is high. There are many studies on the treatment of these diseases, but the research on the factors affecting the development of normal vision is still insufficient.

[0003] Among them, strabismus refers to a state where the visual lines of both eyes are not aligned. Since there is a risk that vision may never recover if not treated early, it must be detected and corrected early in childhood.

[0004] If strabismus appears around the age of 2 to 5, the two eyes of the affected child will see different objects, and as a result, two completely different images will be transmitted to the brain, causing a visual confusion where different objects seem to be seen double. In addition, by feeling the diplopia phenomenon where one image seems to be in different places at the same time, the child will ignore the image coming in from one side in order to eliminate visual confusion and diplopia. As a result, the child will abandon the binocular vision function that makes the child feel objects three-dimensionally, and ultimately give up using the strabismic eye, leading to amblyopia.

[0005] If such symptoms are left untreated, even when an adult wears glasses or lenses or undergoes surgery, the vision cannot be corrected, and the person will be in a state where they can only see with one eye and cannot feel a three-dimensional sense of distance. Therefore, when strabismus appears in a child, early diagnosis and appropriate treatment must be carried out for the sake of vision and quality of life.

[0006] However, when the strabismus angle is small or the fusion ability is good, glasses treatment or visual acuity correction training can be performed, but there are problems such as a long treatment time and a large cost burden.

[0007] Therefore, it is necessary to develop a technology that provides and controls eye movement and visual perception training based on virtual reality in order to improve the visual perception ability including the eye movement ability and stereoscopic sense of a user (test subject).

Summary of the Invention

Problems to be Solved by the Invention

[0008] The present invention has been made in view of the above circumstances, and its object is to provide a virtual reality-based eye movement and visual perception training providing device and method that can prevent further damage to stereoscopic vision due to suppression by providing dichoptic presentation in consideration of the deviation of the user's eyes.

[0009] Another object of the present invention is to change the position of a visual stimulus based on the deviation level and training execution ability of a user to adjust the difficulty level and provide it, so that the user can receive training suitable for his / her own state. Of course, it is to provide a virtual reality-based eye movement and visual perception training providing device and method that can simultaneously perform eye movement (motion) training and visual perception training including recognition of stereoscopic vision.

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The subject to be 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 apparatus according to an embodiment of the present invention.

[0025] FIG. 1 is a diagram for explaining the concept with respect to perspective and training for improving the visual ability and stereoscopic sense of the eyes.

[0026] Strabismus is a visual impairment in which the lines of sight of both eyes do not align and point to different locations. When one eye is looking straight ahead, the other eye is turned inward or outward, or upward or downward. The strabismus may always be misaligned, or there may be moments when the intermittently misaligned line of sight fixes on the front, or when the line of sight fixed on the front is intermittently misaligned.

[0027] Figure 1 shows, as an example, a case where exotropia exists in the right eye of the test subject's eyeballs. When the test subject is looking straight ahead, the left eye is facing forward, but the right eye is facing outward.

[0028] In order to improve the visual ability and stereoscopic perception ability of the eyeballs of such a test subject, training to concentrate the right eye inward, that is, in the center, must be repeatedly performed.

[0029] The present invention enables such eye movement and visual perception training to be performed based on virtual reality.

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

[0031] Referring to Figure 2, a virtual reality-based eye movement and visual perception training providing apparatus (hereinafter referred to as the "training providing apparatus") 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). In particular, when performing wireless communication, it is configured to transmit and receive wireless signals through a communication network using wireless Internet technology.

[0033] As wireless Internet technologies, for example, there are 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), etc. The training providing device 100 will transmit and receive data by at least one wireless Internet technology including even Internet technologies not listed above.

[0034] It is for short-range communication and can support short-range communication by using at least one of Bluetooth (registered trademark) (Bluetooth(registered trademark)), RFID (Radio Frequency Identification), infrared communication (Infrared Data Association; IrDA), UWB (Ultra Wideband), ZigBee (registered trademark), NFC (Near Field Communication), Wi-Fi (registered trademark) (Wireless-Fidelity), Wi-Fi Direct, Wireless USB (Wireless Universal Serial Bus) technologies. At this time, the short-range wireless communication network can be a Wireless Personal Area Networks.

[0035] The input module 130 can acquire a signal corresponding to the input of the subject. For example, the input module 130 can acquire the input of the subject for measurement or training, the response to visual stimuli provided via the display module 150, and the like.

[0036] At this time, the input module 130 can include a keyboard, a keypad, buttons, a jog shuttle, and a wheel, etc. Also, the input of the subject in the input module 130 can be, for example, button pressing, touching, and dragging, etc.

[0037] The input module 130 can be composed of a separate module that is wirelessly or wiredly connected to the training providing device 100. For example, the training providing device 100 provides an image for measurement or training to the subject via the display module 150 attached to the subject's head, and can receive a response from the subject via the input module 130 consisting of a separate module given to the subject's hand.

[0038] The display module 150 outputs images and images. For example, the display module 150 can include an LCD, an OLED, an AMOLED display, etc.

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

[0040] Here, the display module 150 may physically separate the first display and the second display, or may be set by dividing each into a left region and a right region of one display.

[0041] The memory 170 stores various data (information), including at least one piece of data (information) and at least one process necessary for providing virtual reality-based eye movement and visual perception training. For example, programs for training, at least one piece of subject information (personal information, visual information, response information, training results, etc.), various reference values serving as references for measuring the angle of squint and / or stereoscopic effect, measurement videos, training videos, etc. can be stored as data. In addition, the memory 170 stores various command words, algorithms, etc. for performing a virtual reality-based eye movement and visual perception training method.

[0042] Also, the memory 170 can 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.), RAM (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory), magnetic memory, magnetic disk, and optical disk. Further, the memory 170 can store information temporarily, permanently, or semi-permanently, and can be provided in a built-in type or a detachable type.

[0043] The control module 190 is for controlling the components within the training providing apparatus 100 or processing and calculating various information, and controls such that virtual reality-based eye movement and visual perception training are performed based on at least one process stored in the memory 170.

[0044] The control module 190 outputs a first video and a second video that represent dichoptic presentations for inducing binocular disparity on each of the first display and the second display, and acquires visual information about the subject based on the subject's response to the visual stimuli received via the input module 130. Thereafter, the control module 190 controls such that training is performed by changing only the visual stimuli of the video output corresponding to the eye with a squint among the first video and the second video based on the acquired visual information. At this time, the first video and the second video represent the same visual stimuli, and the video output corresponding to the eye with a squint has a visual deviation according to the acquired visual information.

[0045] That is, the control module 190 outputs a first video and a second video that represent visual stimuli to the left eye and the right eye of the subject, leaves the video output corresponding to the eye without a squint among the two videos unchanged, and controls such that movement training of the eye is performed by applying a change only to the video output corresponding to the eye with a squint. That is, training is performed to concentrate the eye with a squint among the two eyes of the subject in a specific direction.

[0046] On the other hand, the visual information can include at least one of squint presence / absence information regarding the left eye and the right eye of the subject and information regarding the degree of squint, i.e., the squint angle and stereoscopic information.

[0047] The control module 190 can measure the perspective angle of the subject by inducing the control module 190 to combine the respective visual stimuli included in the first video and the second video into one image and measuring the moving distance of the subject's line of sight. Further, the control module 190 receives a response to the stimulus with a sense of three-dimensionality among the first display and the second display with respect to the visual stimulus, and receives a response to whether the direction of the three-dimensionality is concave or convex with respect to the stimulus with a sense of three-dimensionality, thereby measuring the three-dimensional sense of the subject.

[0048] The control module 190 can be realized by software, hardware, and combinations thereof. For example, in terms of hardware, the control module 190 can be implemented by an FPGA (Field Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), a semiconductor chip, or various other forms of electronic circuits. Also, for example, in terms of software, the control module 190 can be implemented by a logic program performed by the above-described hardware, various computer languages, and the like.

[0049] Unless otherwise mentioned in the following description, the operations of the training providing apparatus 100 can be understood to be performed under the control of the control module 190.

[0050] The training providing apparatus 100 according to an embodiment of the present invention can include various devices capable of performing arithmetic processing. For example, the training providing apparatus 100 can include a desktop PC, a mobile phone, a smart phone, a laptop computer, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), a slate PC, a tablet PC, an ultrabook, a wearable device, and the like.

[0051] On the one hand, the training providing device 100 can include a head-mounted device such as an HMD (Head Mounted Display), smart glasses, or smart goggles that are worn on the subject's head to display images, or a display device such as a mobile phone that can be placed on the head-mounted device for use.

[0052] On the other hand, the training providing device 100 shown in FIG. 2 is only one example and is not limited thereto. For example, when the display module 150 is realized by a touch screen, the display module 150 can also serve as the input module 130. In this case, an additional input module 130 may not be provided according to the selection, or an input module 130 that performs limited functions such as volume adjustment, power button, and home button can be provided. Also, the display module 150 can 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 output via the display module of the virtual reality-based eye movement and visual perception training providing device according to an embodiment of the present invention, and shows a case where the subject having exotropia in the right eye is controlled to perform training. Also, FIG. 3 shows the display module seen when the subject wears the training providing device 100, and includes a first display 151 arranged in a region corresponding to the left eye of the subject and a second display 152 arranged in a region corresponding to the right eye of the subject.

[0054] As described above, visual stimuli include a reference stimulus and a target stimulus. However, the visual stimuli included in the video output corresponding to the eye with a perspective among the first video and the second video are arranged at positions determined based on the perspective angle in the corresponding video, and are arranged and provided so as to have a difference between the central axis of the reference stimulus and the central axis of the target stimulus in that video. On the other hand, the visual stimuli included in the video output corresponding to the eye without a perspective among the first video and the second video are arranged based on the center of the corresponding video, and the central axis of the reference stimulus and the central axis of the target stimulus in that video are arranged on the same line and provided.

[0055] Referring to FIG. 3, the first video 10 is output via the first display 151 corresponding to the eye without a perspective, and the second video 20 is output via the second display 152 corresponding to the eye with a perspective.

[0056] At this time, both the first video 10 and the second video 20 express visual stimuli, include a heart-shaped object as a reference stimulus, and include a star-shaped object as a target stimulus. However, the first video 10 corresponding to the left eye without a perspective arranges the visual stimulus at the center of the corresponding video, while the second video 20 corresponding to the right eye with a perspective arranges the visual stimulus at a position reflected based on the perspective angle of the subject. Also, the central axis C (coinciding with the central axis of the first video 10) of the first reference stimulus 11 and the central axis D of the first target stimulus 12 expressed in the first video 10 are arranged on the same line, while the central axis C of the second reference stimulus 21 and the central axis D of the second target stimulus 22 expressed in the second video 20 are arranged so as to have a difference.

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

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

[0059] As shown in FIG. 3, the test subject is provided with the first video 10 and the second video 20 simultaneously via the first display 151 and the second display 152, respectively, to induce the combination of the two visual stimuli into one image, whereby the test subject can confirm a visual stimulus such as the third video 30. As a result, the test subject does not feel a three-dimensional effect through the third target stimulus 32, but can feel a three-dimensional effect through the third reference stimulus 31.

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

[0061] Output a first video and a second video including a dichoptic presentation for inducing binocular disparity to each of a plurality of first displays and second displays provided in the training providing apparatus 100, and provide them to the test subject (S210), and receive a response from the test subject to the visual stimulus (S230).

[0062] Acquire visual information about the test subject based on the response (S250), and control the training provided to the test subject by changing only the visual stimulus of the video output corresponding to the eye with a perspective among the first video and the second video based on the acquired visual information (S270).

[0063] Specifically, when controlling the training, while moving the central axis of the target stimulus among the reference stimulus and the target stimulus included in the video output corresponding to the eye with a perspective toward the reference stimulus, control the test subject to perform training on the corresponding eye.

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

[0065] Among the steps of FIG. 5 described above, through the step of acquiring visual information, the training providing apparatus 100 can acquire a perspective angle and stereoscopic effect information as visual information of the subject. Among them, the stereoscopic effect information can be acquired according to the response of the subject.

[0066] Specifically, the training providing apparatus 100 receives a response from the subject to a stimulus in which a stereoscopic effect is felt among the first display and the second display (S251), and receives a response to whether the direction of the stereoscopic effect is concave or convex with respect to the stimulus in which the stereoscopic effect is felt (S253). Thereby, the training providing apparatus 100 can measure the stereoscopic effect of the subject.

[0067] Steps of a method or algorithm described in connection with embodiments of the present invention can be implemented directly in hardware, in a software module executed by hardware, or in a combination thereof. The software module can also always exist in a RAM (Random Access Memory), ROM (Read Only Memory), EPROM (Erasable Programmable ROM), EEPROM (Electrically Erasable Programmable ROM), flash memory, hard disk, removable disk, CD-ROM, or any form of computer-readable recording medium well-known in the technical field to which the present invention pertains.

[0068] As described above, embodiments of the present invention have been described with reference to the accompanying drawings. However, those of ordinary skill in the technical field to which the present invention pertains can understand that the present invention can be implemented in other specific forms without changing its technical idea and essential features. Therefore, the embodiments described above should be understood as being exemplary in all aspects and not restrictive.
