Description

Eye Training and Testing System

The present invention relates to a system for eye training and function testing, and more particularly to a system for eye training and function testing through virtual reality technology.

When reading at close range for a long time or using digital multimedia electronic products, the extraocular muscles (medial rectus and lateral rectus) responsible for adjusting visual distance will be in a tense state, causing spasm and inability to relax, resulting in blurred images when looking far away. The refractive state will produce more myopia than normal. This myopia caused by ciliary muscle spasm is called pseudomyopia.

In order to improve the above-mentioned problems, the industry currently provides an eye training device on the market that can be worn on the head by the user. It has two training modules corresponding to the user's eyes respectively. Each training module includes several lenses with different degrees, and an electric displacement mechanism that can be driven to drive one of the lenses to move and align with one of the user's eyes. By switching to provide lenses with different degrees, the eye muscles can be forced to move in accordance with the change in lens degree, thereby allowing the eye muscles to maintain better accommodation. The eye training device can also be used to detect specific eye diseases, such as strabismus detection and fusional breakdown point detection.

However, when using the eye training device, the user must go to a clinic in person for training and testing, and must be assisted by a professional, which is quite inconvenient.

Therefore, an object of the present invention is to provide an eye training and detection system that can improve at least one disadvantage of the prior art.

Therefore, the eye training and testing system of the present invention is suitable for being implemented by software programs and/or electronic circuits in an electronic carrier that can be placed in front of the user's eyes to display images. The eye training and testing system includes a virtual image display unit and an image change control unit.

The virtual image display unit can display a virtual background image group and a virtual target image group on the electronic device in an overlapping manner. The virtual background image group has a left virtual background image and a right virtual background image that can be viewed to produce a visual effect of being in a three-dimensional virtual space. The virtual target image group has a left virtual target image and a right virtual target image that are respectively overlapped and displayed on the left virtual background image and the right virtual background image.

The image change control unit can control the left virtual target image and the right virtual target image to shift left and right in the left virtual background image and the right virtual background image respectively when being operated to start a convergence training mode, so that the left virtual target image and the right virtual target image change in relative displacement between a fusion position and a separation position.

At the fusion position, the left virtual target image and the right virtual target image can be viewed and fused to form a virtual target suspended in the three-dimensional virtual space. At the separation position, the left virtual target image and the right virtual target image can be viewed to generate a left virtual target and a right virtual target spaced apart in the three-dimensional virtual space.

The effect of the present invention is that through the design of the convergence training mode of the image change control unit, the eye training and testing system of the present invention can simulate the visual effect produced by the prism through VR technology, which can facilitate the user to operate by himself to perform muscle strength training of the extraocular muscles of the eyes.

Another object of the present invention is to provide an eye detection system that can improve at least one disadvantage of the prior art.

Therefore, the eye detection system of the present invention is suitable for being implemented by software programs and/or electronic circuits and constructed in an electronic carrier that can be set in front of the user's eyes to display images. The eye detection system includes a virtual image display unit and an image change control unit.

The virtual image display unit can overlay and display a virtual background image group and a virtual target image group on the electronic carrier. The virtual background image group can be viewed to produce a visual effect of being in a three-dimensional virtual space, and the virtual target image group can be viewed to construct a virtual target suspended in the three-dimensional virtual space.

When the electronic vehicle is operated to activate a converged near-point detection mode, the image change control unit can control the virtual target image group to gradually increase from small to large, and simultaneously adjust the coordinate position of the virtual target image group in the virtual background image group, so that the constructed virtual target produces a visual effect of gradually approaching and increasing from a predetermined initial distance position to the user in the three-dimensional virtual space, and synchronously displays a distance value image in the three-dimensional virtual space to indicate the distance of the virtual target in the three-dimensional virtual space, and the image change control unit will be triggered when the electronic vehicle is operated again, and stop controlling the change of the virtual target image group.

Therefore, the eye detection system of the present invention is suitable for being implemented by software programs and/or electronic circuits and constructed in an electronic carrier that can be set in front of the user's eyes to display images. The eye detection system includes: a virtual image display unit and an image change control unit.

The virtual image display unit can overlap and display a virtual background image group and a virtual target image group on the electronic carrier. The virtual background image group has a left virtual background image and a right virtual background image that can be viewed to produce a visual effect of being in a three-dimensional virtual space. The virtual target image group has a left virtual target image and a right virtual target image that are overlapped and displayed on the left virtual background image and the right virtual background image, respectively.

When the image change control unit is operated to start a hidden squint detection mode, the left virtual target formed by the left virtual target image in the three-dimensional virtual space produces a visual effect of moving down by a specific BU prism amount, and the right virtual target formed by the right virtual target image in the three-dimensional virtual space produces a visual effect of moving right by a predetermined BI prism amount relative to the left virtual target. Then, the BI prism amount is gradually changed so that the right virtual target gradually moves left to the upper left of the left virtual target. Then, it gradually moves right and returns to the upper right of the left virtual target. The image change control unit records the BI prism volume corresponding to the position of the right virtual target in the three-dimensional virtual space when the user operates the electronic carrier by moving the right virtual target to be aligned with the left virtual target in the vertical direction.

The effect of the present invention is that through the design of the convergence near point detection mode and the latent strabismus detection mode of the image change control unit, the eye detection system of the present invention can detect the convergence near point and latent strabismus of the eyes through VR technology, and can be convenient for users to operate and use by themselves.

Referring to FIGS. 1 and 2 , an embodiment of the eye training and detection system 200 of the present invention is applicable to an electronic carrier 900 that can display images and can be operated by the electronic carrier 900 to activate functions. In this embodiment, the electronic carrier 900 is a mobile phone or other electronic device that can be set in a VR case 800. The VR case 800 can be operated to control the electronic carrier 900 to activate the function of the eye training and detection system 200. However, in other embodiments of the present invention, the electronic carrier 900 can also be a VR host with image display function. The electronic carrier 900 has a dynamic sensor 901 that can sense its own movement and generate a displacement signal.

Since the VR case 800 can control the electronic carrier 900 to activate the function of the eye training and detection system 200, or the electronic carrier 900 of the VR host type can be operated to activate the function of the eye training and detection system 200, both are existing technologies and are not the focus of improvement of the present invention, and therefore will not be described in detail.

2, 3, 7, and 9, the eye training and detection system 200 includes a virtual image display unit 3, an image change control unit 4, and a motion analysis unit 5, and the eye training and detection system 200 has a built-in virtual background image group 61, a virtual target image group 62, a cursor image group 63, a setting button image group 64, a return button image group 65, and a virtual speed adjustment image 66 for display through virtual reality (VR) technology. The image groups all have two images for being arranged left and right and displayed on the screen 902 (shown in FIG. 1) of the electronic carrier 900, and for the user to watch with both eyes to produce a three-dimensional visual effect.

The virtual background image group 61 includes a left virtual background image 611 and a right virtual background image 612. The virtual target image group 62 includes a left virtual target image 621 and a right virtual target image 622. The cursor image group 63 includes two cursor images 631. The setting button image group 64 includes two setting button images 641. The reset button image group 65 includes two reset button images 651.

The virtual image display unit 3 can display the virtual background image group 61 on the screen 902 of the electronic carrier 900 through virtual reality (VR) technology, so that the left virtual background image 611 and the right virtual background image 612 can be viewed by the user, thereby constructing a visual effect of being in a three-dimensional virtual space 610.

The virtual image display unit 3 can also use virtual reality (VR) technology to overlay and display the virtual target image group 62, the cursor image group 63, the setting button image group 64, the return button image group 65 and the virtual speed adjustment image 66 on the virtual background image group 61 currently displayed by the electronic vehicle 900. The left virtual target image 621 and the right virtual target image 622 of the virtual target image group 62 are available for viewing by the user, thereby constructing a virtual target 620 suspended in the three-dimensional virtual space 610.

The cursor image group 63, the setting button image group 64 and the return button image group 65 are viewable and respectively construct a virtual cursor 630, a virtual setting button 640 and a virtual return button 650 suspended in the three-dimensional virtual space 610. The virtual speed adjustment image 66 is viewable and constructs a virtual speed adjustment screen 660 located in the three-dimensional virtual space 610. The virtual speed adjustment screen 660 displays a moving speed value 663, and has two virtual speed adjustment buttons 661 representing deceleration and acceleration, respectively, and a virtual confirmation button 662.

Since displaying the image groups and images using virtual reality (VR) technology is an existing technology and is not the focus of improvement of the present invention, it will not be described in detail.

The motion analysis unit 5 can analyze the motion signal generated by the dynamic sensor 901 of the electronic vehicle 900 to determine the direction and amplitude of the movement of the electronic vehicle 900, and correspondingly control the virtual cursor 630 to move relative to the virtual setting button 640, the virtual reset button 650 and the virtual speed adjustment screen 660 in the three-dimensional virtual space 610.

The image change control unit 4 has a built-in vergence training mode 41, a convergence near point detection mode 42, and a cryptic strabismus detection mode 43, which can be controlled by the electronic carrier 900 to switch and activate one of the modes.

Referring to 2, 4, 5, and 6, when the image change control unit 4 starts the vergence training mode 41, it controls the virtual image display unit 3 to overlay the left virtual target image 621 on the left virtual background image 611, and overlay the right virtual target image 622 on the right virtual background image 612. Then, the left virtual target image 621 and the right virtual target image 622 are controlled to shift left and right in the left virtual background image 611 and the right virtual background image 612, respectively. In this embodiment, the left-right displacement refers to the left-right constant speed displacement of a predetermined distance away from each other and the left-right constant speed displacement of a predetermined distance towards each other, so that the left virtual target image 621 and the right virtual target image 622 change their relative displacement between a fusion position and a separation position.

In the fused position, the left virtual target image 621 and the right virtual target image 622 can be viewed and fused to form the virtual target 620 suspended in the three-dimensional virtual space 610, as shown in Figure 4. In the separated position, the left virtual target image 621 and the right virtual target image 622 can be viewed to generate a left virtual target 623 and a right virtual target 624 spaced apart in the three-dimensional virtual space 610, as shown in Figure 6.

In addition, when the image change control unit 4 activates the convergence training mode 41, it will also control the virtual image display unit 3 to overlap and display the cursor image group 63 and the setting button image group 64 in the virtual background image group 61, so that the cursor image group 63 and the setting button image group 64 can be viewed to respectively constitute the virtual cursor 630 and the virtual setting button 640.

5 , 7 , and 8 , when the user wants to adjust the displacement speed of the left virtual target image 621 and the right virtual target image 622 , the user can rotate the head to drive the electronic carrier 900 (shown in FIG. 1 ) to move, and the motion analysis unit 5 will correspondingly control the virtual cursor 630 to move relative to the virtual setting button 640 in the three-dimensional virtual space 610 . When the virtual cursor 630 overlaps with the virtual setting button 640 and the electronic vehicle 900 is operated, the image change control unit 4 drives the virtual image display unit 3 to overlap and display the virtual speed adjustment image 66 on the virtual background image group 61, thereby constructing a virtual speed adjustment screen 660 for viewing.

When the user continues to turn his head, the motion analysis unit 5 will control the virtual cursor 630 to move relative to the virtual speed adjustment screen 660 in the three-dimensional virtual space 610. The image change control unit 4 will be triggered when the virtual cursor 630 and one of the virtual speed adjustment buttons 661 are overlapped and the electronic vehicle 900 is operated, and will adjust the motion speed value 663 displayed on the virtual speed adjustment screen 660 accordingly, and will be triggered when the virtual cursor 630 and the virtual confirmation button 662 are overlapped and the electronic vehicle 900 is operated, and will store the currently adjusted motion speed value 663. When the image change control unit 4 is operated again to start the convergence training mode 41, it controls the speed of the left virtual target image 621 and the right virtual target image 622 moving left and right in the left virtual background image 611 and the right virtual background image 612 respectively according to the currently set moving speed value 663.

The present invention can control the change of the left virtual target image 621 and the right virtual target image 622 at the fusion position and the separation position when the image change control unit 4 starts the vergence training mode 41, which can be used to automatically simulate the horizontal vergence prism training effect, and can use the destruction of fusion image to stimulate the contraction and relaxation of the lateral rectus and medial rectus muscles in the extraocular muscles, so as to achieve the purpose of training the strength of the extraocular muscles.

2, 9, and 10, when the converged near point detection mode 42 is activated, the image change control unit 4 controls the virtual image display unit 3 to overlay and display the virtual target image group 62 on the virtual background image group 61. The image change control unit 4 controls the virtual target image group 62 to gradually increase from an initial size, and simultaneously adjusts the coordinate position of the virtual target image group 62 in the virtual background image group 61, so that the virtual target 620 in the three-dimensional virtual space 610 produces a visual effect of gradually approaching the user from a predetermined initial distance position and gradually increasing in size.

At the same time, the image change control unit 4 will also control the virtual image display unit 3 to display a distance numerical image 67 superimposed on the virtual background image group 61, and when controlling the virtual target 620 to move closer to the user, the distance numerical image 67 will be synchronously driven to indicate the distance of the virtual target 620 relative to the user in the three-dimensional virtual space 610.

When the user sees the virtual target 620 gradually approaching him/herself and the virtual target 620 splits from one into two, the user can immediately operate the electronic carrier 900 (shown in FIG. 1 ), and the image change control unit 4 will be triggered to stop controlling the change of the virtual target image group 62, that is, to stop the displacement of the virtual target 620. At this time, the distance indicated by the distance value image 67 is the user's near point of convergence (NPC) distance, which can be used for medical personnel to refer to and judge the near point fusion ability of the user's eyes.

When the converged near point detection mode 42 is activated, the image change control unit 4 will simultaneously control the virtual image display unit 3 to display the cursor image group 63 and the return button image group 65 on the virtual background image group 61, so that the user can view and construct the virtual cursor 630 and the virtual return button 650 in the three-dimensional virtual space 610. When the user wants to reset the virtual target 620 to the predetermined initial distance position, the user can rotate the head to drive the electronic carrier 900 to move, and the movement analysis unit 5 will control the virtual cursor 630 to move relative to the virtual return button 650 in the three-dimensional virtual space 610 accordingly. The image change control unit 4 is triggered when the virtual cursor 630 and the virtual return button 650 overlap and the electronic carrier 900 is operated, and adjusts the size and coordinate position of the virtual target image group 62 to restore the virtual target 620 to the visual state of the predetermined initial distance position in the three-dimensional virtual space 610.

2 , 11 , and 12 , when the hidden squint detection mode 43 is activated, the image change control unit 4 controls the virtual image display unit 3 to display the virtual target image set 62 superimposed on the virtual background image set 61 . Then, the image change control unit 4 will shift the left virtual target image 621 relative to the left virtual background image 611, and shift the right virtual target image 622 relative to the right virtual background image 612, so that the left virtual target 623 formed by the left virtual target image 621 in the three-dimensional virtual space 610 will produce a visual effect of moving downward by a specific BU prism amount, and at the same time, the right virtual target image 624 formed by the right virtual target image 622 in the three-dimensional virtual space 610 will produce a visual effect of moving right by a predetermined BI prism amount relative to the left virtual target 623.

In this embodiment, the left virtual target image 621 generates a 6 BU prism, and the right virtual target image 622 generates a 12 BI prism. However, the implementation is not limited to this.

Next, the BI prism amount is gradually reduced, for example, the BI prism amount is changed by 2 BI per second, so that the right virtual target 624 gradually moves to the left to the upper left of the left virtual target 623, and then the BI prism amount is gradually increased, for example, the BI prism amount is changed by 2 BI per second, so that the right virtual target 624 gradually moves to the right to the upper right of the left virtual target 623. In the above process of shifting the right virtual target 624, the user can operate the electronic carrier 900 when observing and judging that the right virtual target 624 and the left virtual target 623 are aligned vertically. The image change control unit 4 is triggered by the electronic carrier 900 to record the BI prism corresponding to the position of the right virtual target 624 in the three-dimensional virtual space 610, and two BI prism values are obtained.

In order to maintain binocular single vision, normal people will keep their eyes in the right position under fusion control. However, when the eyes are too tired, they may not be able to maintain the right position, and a latent strabismus will be generated. The present invention can use VR imaging technology to simulate the change of prism visual effect without using prisms, and quickly detect the latent strabismus of the user, which can be used by medical staff to judge whether the strength of the binocular oblique muscles of the user is balanced.

In summary, through the design of the vergence training mode 41, the convergence near point detection mode 42 and the occult strabismus detection mode 43 of the image change control unit 4, the eye training and detection system 200 of the present invention can simulate various visual effects produced by prisms through VR technology, and can be used for muscle strength training of the extraocular muscles of the eyes, detection of the convergence near point, and detection of occult strabismus. Moreover, the eye training and detection system 200 can also be loaded on the electronic carrier 900 in the form of APP (mobile application), and can be operated and used by the user himself without the assistance of a professional optometrist, which is quite convenient and practical. Therefore, the eye training and detection system 200 of the present invention can indeed achieve the purpose of the present invention.

However, the above is only an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.

The eye detection system includes: A virtual image display unit that can overlap and display a virtual background image group and a virtual target image group on the electronic carrier, the virtual background image group has a left virtual background image and a right virtual background image that can be viewed to produce a visual effect of being in a three-dimensional virtual space, and the virtual target image group has a left virtual target image and a right virtual target image that are overlapped and displayed on the left virtual background image and the right virtual background image respectively; and An image change control unit can, when the electronic vehicle is operated to activate a hidden squint detection mode, make the left virtual target formed by the left virtual target image in the three-dimensional virtual space produce a visual effect of moving down by a specific BU prism amount, and make the right virtual target formed by the right virtual target image in the three-dimensional virtual space produce a visual effect of moving right by a predetermined BI prism amount relative to the left virtual target, and then After that, the BI prism volume is gradually changed, so that the right virtual target gradually moves to the left to the upper left of the left virtual target, and then gradually moves to the right to the upper right of the left virtual target. The image change control unit will record the BI prism volume corresponding to the position of the right virtual target in the three-dimensional virtual space when the user operates the electronic vehicle by moving the right virtual target to align with the left virtual target up and down. An eye detection device as described in claim 8, wherein the image change control unit, when activating the strabismus detection mode, causes the left virtual target to move downward by 6 BU prism amount, and causes the right virtual target to gradually reduce the BI prism amount from the 12 BI prism amount relatively located at the upper right of the left virtual target, so that the right virtual target gradually moves leftward to the upper left of the left virtual target, and then gradually increases the BI prism amount, so that the right virtual target gradually moves rightward and returns to the upper right of the left virtual target. An eye detection device as described in claim 9, wherein the image change control unit moves the right virtual target left and right at a speed of adjusting 2 BI prism volume per second.
