The parts of this type of equipment are complex and have a low reuse rate. They cannot directly transmit the parameters that need to be controlled, and there are certain measurement errors. In addition, the motion control of this type of equipment is also relatively complex. Most of them can only achieve rotation in a single direction, and cannot simply and efficiently simulate the complex rotation of the human eye.

[0058] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure.

[0059] The eye simulation device according to an embodiment of the present disclosure is described below with reference to FIG. 1 to FIG. 5 .

[0060] As shown in FIG1 , the eye simulation device includes a simulated eyeball 100 , a first rotating component and a second rotating component. The first rotating component is connected to the simulated eyeball 100 , and the second rotating component is connected to the simulated eyeball 100 .

[0061] The simulated eyeball 100 may be a spherical structure simulating a human eye, and the first rotating component and the second rotating component are both connected to the simulated eyeball 100 to perform transmission to simulate the rotation of a human eye.

[0062] As shown in Figure 3, the simulated eyeball 100 can include an eyeball body 101 and an eyeball bulge 102. The eyeball body 101 can simulate the vitreous structure of the human eye, and the eyeball bulge 102 can be a partial structure of the lens and cornea, that is, the pupil of the simulated eyeball 100 is located at the eyeball bulge 102.

[0063] The size of the simulated eyeball 100 can be adjusted according to different simulation requirements. It can simulate the size of a normal eyeball or the size of an irregular eyeball caused by a disease or other reasons.

[0064] For example, the simulated eyeball 100 has an anterior-posterior diameter of 24 mm, a vertical diameter of 22.6 mm to 23 mm, and a horizontal diameter of 23.4 mm to 24.2 mm.

[0065] In actual implementation, materials that meet the optical properties of the human eye can be selected to prepare the simulated eyeball 100. The preparation materials used for the eyeball body 101 and the eyeball protrusion 102 can be different, which can more realistically simulate the visual characteristics of the human eye.

[0066] In this embodiment, the first rotating component is used to drive the simulated eyeball 100 to rotate in the vertical plane where the first axis is located with the center point of the simulated eyeball 100 as the center of the circle, and the second rotating component is used to drive the simulated eyeball 100 to rotate around the second axis, and the second axis forms an angle with the horizontal plane.

[0067] It should be noted that the first axis and the second axis may be virtual axes, or may be axes of real rotating shafts on the first rotating component and the second rotating component.

[0068] When the first rotating component drives the simulated eyeball 100 to rotate in the vertical plane where the first axis is located with the center point of the simulated eyeball 100 as the center, the position of any point on the simulated eyeball 100 except the center point in the vertical direction changes.

[0069] In this embodiment, the vertical position of the pupil at the eyeball bulge 102 changes, and the pitch angle of the simulated eyeball 100 changes. The simulated eyeball 100 is driven to rotate by the first rotating component, so that the pitch angle of the simulated eyeball 100 can be adjusted.

[0070] It can be understood that the second axis forms an angle with the horizontal plane, the second axis is not an axis in the horizontal direction, and the angle α between the second axis and the horizontal plane has a value range of 0 degrees < α ≤ 90 degrees.

[0071] The second rotating component drives the simulated eyeball 100 to rotate around the second axis. The second axis is the rotation axis of the simulated eyeball 100. Except for the point at the second axis, the horizontal position of any point on the simulated eyeball 100 changes.

[0072] In this embodiment, the horizontal position of the pupil at the eyeball bulge 102 changes, and the azimuth angle of the simulated eyeball 100 changes. The simulated eyeball 100 is driven to rotate by the second rotating component, so that the azimuth angle of the simulated eyeball 100 can be adjusted.

[0073] In actual implementation, the rotation center of the simulated eyeball 100 can be the center point of the simulated eyeball. The first rotating component drives the simulated eyeball 100 to pitch and roll, and the points on the surface of the simulated eyeball 100 move around the center point of the simulated eyeball 100, and its motion trajectory is an arc; the second rotating component drives the simulated eyeball 100 to rotate horizontally. By combining horizontal rotation and pitch movement, the complex rotation of the human eye can be simulated simply and efficiently.

[0074] In this embodiment, the first rotating component and the second rotating component are directly connected to the simulated eyeball 100 to realize transmission, and the parameters controlled by the simulated eyeball 100 can be directly transmitted to the first rotating component and the second rotating component, thereby realizing precise movement control of the simulated eyeball 100.

[0075] For example, the current pitch angle of the simulated eyeball 100 is 0 degrees, and the pitch angle of the simulated eyeball 100 needs to be adjusted to 30 degrees upward. The corresponding control parameters are directly transmitted to the first rotating component, and the first rotating component is transmitted so that the first axis is 30 degrees upward.

[0076] For another example, the simulated eyeball 100 is looking straight ahead, and the current azimuth angle is 0 degrees. The azimuth angle of the simulated eyeball 100 needs to be adjusted to 20 degrees to the left, and the corresponding control parameters are directly transmitted to the second rotating component, and the second rotating component can be driven to rotate 20 degrees around the second axis.

[0077] For another example, the simulated eyeball 100 is looking straight ahead, and the current pitch angle and azimuth angle of the simulated eyeball 100 are both 0 degrees. A tracking point in space is located diagonally in front of the simulated eyeball 100. If you want to look at the tracking point, you need to adjust the azimuth angle of the simulated eyeball 100 to 20 degrees to the left and the pitch angle to 30 degrees upward. The control parameters of the two angle adjustments are transmitted to the first rotating component and the second rotating component respectively. The first rotating component drives the first axis upward 30 degrees, and the second rotating component drives the second axis to rotate 20 degrees, so that the simulated eyeball 100 looks at the tracking point.

[0078] In related technologies, most test equipment that simulates the human eye uses connecting rods or gears for transmission to simulate the rotation of the human eye. The parts of this type of equipment are complex and have a low reuse rate. They cannot directly transmit the parameters that need to be controlled, and there are certain measurement errors. In addition, the motion control of this type of equipment is relatively complex. Most of them can only achieve rotation in a single direction, and cannot simply and efficiently simulate the complex rotation of the human eye.

[0079] The disclosed embodiment drives the simulated eyeball 100 to perform pitch motion through the first rotating component, and drives the simulated eyeball 100 to rotate through the second rotating component. The first rotating component and the second rotating component are directly connected to the simulated eyeball 100 to realize transmission, and the spatial rotation of the simulated eyeball 100 is realized by rotating in the horizontal and vertical directions. The device has a simple structure and high scalability. The parameters that need to be controlled can be directly transmitted to the first rotating component and the second rotating component, effectively reducing the test error. The size, rotation range and movement mode of the real eyeball can be accurately simulated. At the same time, when the distance from the center point of the simulated eyeball 100 to the anterior pole of the eyeball is guaranteed, the simulation of irregular eyeball movements can also be realized.

[0080] According to the eye simulation device provided by the embodiment of the present disclosure, the first rotating component and the second rotating component drive the simulated eyeball 100 to perform pitch motion and horizontal rotation, thereby realizing the spatial rotation effect of the eyeball. The structure is simple, and the control parameters can be directly transmitted to the rotating components, which can simply and efficiently simulate the complex rotation of the human eye.

[0081] In some embodiments, the first axis and the second axis intersect at the center point of the simulated eyeball 100.

[0082] It should be noted that the first axis and the second axis intersect at the center point of the simulated eyeball 100. When the distance from the center point of the simulated eyeball 100 to the anterior pole of the eyeball is determined, the rotation of the simulated eyeball 100 is not restricted by the shape of the eyeball, and normal eyeballs and irregular eyeballs caused by lesions or other reasons can be simulated. The first rotating component drives the simulated eyeball 100 to rotate in the vertical plane where the first axis is located, and the second rotating component drives the simulated eyeball 100 to rotate horizontally around the second axis.

[0083] In this embodiment, the first axis and the second axis intersect at the center point of the simulated eyeball 100. The rotation center of the simulated eyeball 100 is the center point of the simulated eyeball. The first rotating component drives the simulated eyeball 100 to move around the center point of the simulated eyeball 100; the second rotating component drives the simulated eyeball 100 to rotate horizontally around the second axis where the center point of the simulated eyeball 100 is located. By controlling the horizontal rotation and pitch movement, the complex rotation of the human eye can be simulated simply and efficiently.

[0084] In some embodiments, the eye simulation device is used to control at least one of the first rotating component and the second rotating component to drive the simulated eyeball to rotate based on the tracking point coordinate information of the target tracking point, so that the simulated eyeball looks at the target tracking point.

[0085] In this embodiment, based on the tracking point coordinate information of the target tracking point, the control parameters required for the simulated eyeball 100 to rotate from the current position to the position of gazing at the target tracking point are calculated, and the first rotating component and the second rotating component drive the simulated eyeball 100 to rotate according to their respective control parameters, so that the simulated eyeball 100 gazes at the target tracking point.

[0086] For example, the current pitch angle of the simulated eyeball 100 is 0 degrees. According to the tracking point coordinate information of the target tracking point, it is calculated that if the simulated eyeball 100 is to look at the target gaze point, the pitch angle of the simulated eyeball 100 needs to be adjusted to 30 degrees upward. The corresponding control parameters are directly transmitted to the first rotating component. The first rotating component drives the simulated eyeball 100 upward 30 degrees, and the second rotating component does not rotate, so that the simulated eyeball 100 looks at the target tracking point.

[0087] For another example, the current pitch angle and azimuth angle of the simulated eyeball 100 are both 0 degrees. According to the tracking point coordinate information of the target tracking point, it is calculated that if the simulated eyeball 100 is to look at the target gaze point, the azimuth angle of the simulated eyeball 100 needs to be adjusted to 20 degrees to the left and the pitch angle needs to be adjusted to 30 degrees upward. The control parameters of the two angle adjustments are transmitted to the first rotating component and the second rotating component respectively. The first rotating component drives the simulated eyeball 100 upward 30 degrees, and the second rotating component drives the simulated eyeball 100 to rotate 20 degrees, so that the simulated eyeball 100 looks at the target tracking point.

[0088] In some embodiments, the tracking point coordinate information is input by a user.

[0089] In this embodiment, the user inputs tracking point coordinate information, and the eye simulation device controls the rotation of the first rotating component and the second rotating component according to the tracking point coordinate information input by the user, so that the simulated eyeball 100 gazes at the target tracking point.

[0090] In actual implementation, the user input corresponding to the tracking point coordinate information can be a touch operation, including but not limited to click operations, sliding operations and pressing operations of the eye simulation device or other terminal devices connected to the eye simulation device; it can also be physical button input or voice input.

[0091] Of course, in other embodiments, the user input corresponding to the tracking point coordinate information may also be in other forms, including but not limited to character input, etc., which can be determined according to actual needs and is not limited in this embodiment of the present disclosure.

[0092] In some embodiments, the tracking point coordinate information is obtained by the eye simulation device based on image recognition of the target tracking point.

[0093] In this embodiment, the eye simulation device identifies the target tracking point based on the image and obtains the tracking point coordinate information of the target tracking point, thereby achieving full automation of simulating the eyeball 100 gazing at the target tracking point.

[0094] The structures of the simulated eyeball 100, the first rotating component and the second rotating component are respectively introduced in detail below.

[0095] In some embodiments, the first rotating assembly includes a connecting rod 210 and a first driving assembly.

[0096] The connecting rod 210 is a transmission component, and the first driving assembly is a component that can output power to rotate the connecting rod 210 in a vertical plane where the first axis is located.

[0097] In this embodiment, one end of the connecting rod 210 is connected to the simulated eyeball 100 at a first connection point, and the line connecting the first connection point and the center point of the simulated eyeball 100 is the first axis; the other end of the connecting rod 210 is connected to the first driving assembly, and the first driving assembly is used to drive the connecting rod 210 to rotate in the vertical plane where the first axis is located with the center point of the simulated eyeball 100 as the center of the circle.

[0098] It should be noted that the connecting rod 210 is directly connected to the simulated eyeball 100, and the angle of rotation of the connecting rod 210 on the vertical plane is directly transmitted to the simulated eyeball 100. The simulated eyeball 100 also rotates the same angle on the vertical plane, which can effectively ensure the direct transmission of the control effect of the first rotating component.

[0099] For example, as shown in Figure 2, the connecting rod 210 is directly connected to the simulated eyeball 100, one end of the connecting rod 210 is connected to the simulated eyeball 100 at a first connection point, and the other end of the connecting rod 210 is connected to the first driving component. The other end of the connecting rod 210 rotates upward 30 degrees under the drive of the first driving component, and the simulated eyeball 100 rotates downward 30 degrees accordingly.

[0100] In some embodiments, the first driving assembly includes: an angle stage 220 .

[0101] The angle table 220, also called an angle adjuster, can rotate the components connected to the angle table 220 around a fixed angle center. The angle table 220 can also be displayed with a scale to indicate the angle of rotation.

[0102] In this embodiment, the output end of the angle table 220 is connected to the other end of the connecting rod 210, and the angle table 220 is used to drive the connecting rod 210 to swing in the vertical plane where the first axis is located with the center point of the simulated eyeball 100 as the center of the circle.

[0103] It should be noted that the connecting rod 210 connected to the angle table 220 is not retractable. When the angle table 220 drives the connecting rod 210 to swing in the vertical plane where the first axis is located, the motion trajectory of the other end of the connecting rod 210 is an arc, and the center of the arc trajectory is the center point of the simulated eyeball 100.

[0104] The center point of the simulated eyeball 100 is the swing angle center of the angle platform 220 , and the angle platform 220 drives the connecting rod 210 to rotate up and down around the swing angle center to achieve adjustment of the pitch angle.

[0105] It can be understood that the connecting rod 210 is directly connected to the simulated eyeball 100, and the angle table 220 serves as the first driving component, which can effectively ensure the direct transmission of the control effect of the first rotating component and accurately control the up and down rotation angle of the simulated eyeball 100.

[0106] In actual implementation, an appropriate angle platform 220 may be selected according to the angle range of the simulated eyeball 100 rotating up and down in the vertical direction.

[0107] In some embodiments, the connecting rod 210 is a telescopic rod, one end of which is connected to the simulated eyeball 100 , and the first driving assembly includes: a first driving device.

[0108] In this embodiment, the output end of the first driving device is connected to the other end of the telescopic rod, and the first driving device is used to drive the telescopic rod to rotate in the vertical plane where the first axis is located with the center point of the simulated eyeball as the center of the circle.

[0109] It can be understood that the first driving device can be a driving motor that provides vertical movement for the other end of the telescopic rod. Under the drive of the first driving device, the other end of the telescopic rod moves in the vertical direction. The movement trajectory of the other end of the telescopic rod is a straight line. The length of the telescopic rod changes during movement, and the telescopic rod as a whole rotates in the vertical plane where the first axis is located with the center point of the simulated eyeball as the center of the circle.

[0110] In actual implementation, when the telescopic rod is placed horizontally, its length is the shortest; when the other end of the telescopic rod moves upward or downward from a horizontal position under the drive of the first driving device, its length gradually becomes longer; the telescopic length range of the telescopic rod can be determined according to the angle range of the simulated eyeball 100 rotating in the vertical plane where the first axis is located.

[0111] In some embodiments, the range of rotation of the simulated eyeball 100 in the vertical plane where the first axis is located is ±45 degrees.

[0112] In this embodiment, an angular table 220 or other first driving component with a rotation range of ±45 degrees can be selected, so that the first rotating component can drive the simulated eyeball 100 to rotate a total of 90 degrees in the vertical plane where the first axis is located, that is, it can be rotated upward to a position with an angle of 45 degrees with the horizontal plane, and it can also be rotated downward to a position with an angle of 45 degrees with the horizontal plane.

[0113] It should be noted that the real human eye can rotate 60 degrees upward and 75 degrees downward, a total of 135 degrees. The comfort angle of the human eye is 60 degrees in total. The simulated eyeball 100 can rotate up and down a total of 90 degrees, which can ensure full coverage of the comfort angle range.

[0114] In some embodiments, the eye simulation device may further include: a simulated eyeball fixation frame 310 .

[0115] In this embodiment, the simulated eyeball fixing frame 310 is used to fix the simulated eyeball 100. The simulated eyeball 100 is installed in the simulated eyeball fixing frame 310. The center of the simulated eyeball fixing frame 310 coincides with the center of the simulated eyeball 100 (i.e., the center point).

[0116] In actual implementation, the simulated eyeball fixing frame 310 can limit the angular range of the simulated eyeball 100 rotation. For example, the simulated eyeball fixing frame 310 is used to limit the rotation range of the simulated eyeball 100 in the vertical plane where the first axis is located to ±45 degrees.

[0117] In actual implementation, the inner surface of the simulated eyeball fixing frame 310 matches the outer surface shape of the simulated eyeball 100, and the inner surface of the simulated eyeball fixing frame 310 and the outer surface of the simulated eyeball 100 have the same spherical structure, which can ensure that after the simulated eyeball 100 is placed in the simulated eyeball fixing frame 310, the center of the simulated eyeball fixing frame 310 coincides with the center of the simulated eyeball 100 (i.e., the center point).

[0118] The simulated eyeball fixing frame 310 can not only ensure the free up and down rotation of the simulated eyeball 100, but also limit the eyeball rotation range through the boundary of the simulated eyeball fixing frame 310 to meet the different rotation range requirements of the simulated eyeball 100.

[0119] In some embodiments, the simulated eyeball fixing frame 310 is provided with a limiting structure 320 in the direction of the line of sight of the simulated eyeball 100 , and when the simulated eyeball 100 is at the maximum rotation angle, the limiting structure 320 stops at the simulated eyeball 100 .

[0120] As shown in Figure 5, the simulated eyeball fixing frame 310 is provided with a limiting structure 320 in the direction of the line of sight of the simulated eyeball 100. When the simulated eyeball 100 is at the maximum rotation angle, that is, rotated 45 degrees upward or 45 degrees downward, the limiting structure 320 stops at the simulated eyeball 100, limiting the rotation range of the simulated eyeball 100.

[0121] In actual implementation, a plurality of limiting structures 320 may be provided along the circumferential direction of the simulated eyeball fixation frame 310 .

[0122] In some embodiments, the simulated eyeball fixing frame 310 may also be provided with a limiting structure 320 in the direction of sight emission of the simulated eyeball 100 , and when the simulated eyeball 100 is at the maximum rotation angle, the limiting structure 320 stops at the simulated eyeball 100 .

[0123] In this embodiment, a limiting structure 320 is provided on the simulated eyeball fixing frame 310 away from the line of sight emitting direction of the simulated eyeball 100. When the simulated eyeball 100 is at the maximum rotation angle, the simulated eyeball 100 or the connecting rod 210 interferes with the limiting structure 320, and the limiting structure 320 stops at the simulated eyeball 100, limiting the rotation range of the simulated eyeball 100.

[0124] In some embodiments, the simulated eyeball fixing frame 310 includes a first fixing frame 311 and a second fixing frame 312 . The flange of the second fixing frame 312 is nested in the first fixing frame 311 , and the limiting structure 320 is provided at the edge of the first fixing frame 311 .

[0125] As shown in Figure 4, the second fixed frame 312 is provided with a flange on the side facing the first fixed frame 311, and the flange of the second fixed frame 312 is nested in the first fixed frame 311. After the first fixed frame 311 and the second fixed frame 312 are installed together, their inner surfaces have the same spherical structure as the outer surface of the simulated eyeball 100.

[0126] The first fixed frame 311 is a frame that simulates the direction of sight of the eyeball 100 , and the limiting structure 320 is disposed at an edge of the first fixed frame 311 .

[0127] In some embodiments, the simulated eyeball fixing frame 310 may include two or more fixing frames, which are connected to form the simulated eyeball fixing frame 310 .

[0128] For example, the simulated eyeball fixing frame 310 includes two fixing frames, which are upper and lower structures and are connected together by connecting components such as screws and bolts.

[0129] In some embodiments, the simulated eyeball 100 can rotate around the second axis in a range of 360 degrees.

[0130] In this embodiment, the simulated eyeball 100 can rotate around the second axis in a full range of 360 degrees, and a second rotating component that can rotate 360 ​​degrees can be selected.

[0131] It should be noted that the horizontal rotation range of a real human eye can be 95 degrees outward (away from the other eye) and 60 degrees inward (toward the other eye). The overlapping field of view of the two eyes is 120 degrees, and the comfort angle is 60 degrees.

[0132] In this embodiment, the simulated eyeball 100 can rotate 360 ​​degrees around the second axis, which can ensure full coverage of the left and right eye movement ranges and simplify the structure of the second rotating component without the need for additional limiting devices.

[0133] In some embodiments, the second rotating component includes a rotating turntable 410 .

[0134] In this embodiment, the simulated eyeball 100 is disposed on a rotating turntable 410 , the rotation center of the rotating turntable 410 coincides with the center point of the simulated eyeball 100 , and the rotation range of the rotating turntable 410 is 360 degrees.

[0135] In actual implementation, an optical rotation turntable 410 may be used to ensure rotation accuracy.

[0136] In some embodiments, the eye simulation device may further include a first lifting structure.

[0137] In this embodiment, the first rotating assembly is installed on the first lifting structure, and the first lifting structure is used to drive the first rotating assembly to move up and down.

[0138] In actual implementation, the vertical height of the first rotating component can be adjusted according to different test eyeballs.

[0139] For example, the first rotating component includes a connecting rod 210 and an angle platform 220, and the first lifting structure is an angle platform lifting connecting plate 222. The angle platform 220 is fixed to the angle platform lifting connecting plate 222 through an angle platform fixing plate 221. The angle platform lifting connecting plate 222 can be lifted and lowered by structures such as gears, racks or threads.

[0140] It can be understood that the first rotating assembly is connected to the simulated eyeball 100, and when the height of the first rotating assembly is adjusted through the first lifting structure, the height of the simulated eyeball 100 is also adjusted accordingly.

[0141] In some embodiments, the eye simulation device may further include an eyeball support 110 .

[0142] In this embodiment, the simulated eyeball 100 is mounted on an eyeball support 110 , which is a liftable support.

[0143] The eyeball support 110 is used to support the simulated eyeball 100. The eyeball support 110 is a liftable support that can adjust the height of the simulated eyeball 100 synchronously when the first lifting structure adjusts the height of the first rotating component.

[0144] In actual implementation, the eyeball support 110 can be a telescopic rod, a sleeve or other structures.

[0145] In some embodiments, the eye simulation device may further include a component connection structure.

[0146] In this embodiment, the component connection structure is connected to the second rotating component, and the first rotating component is installed on the component connection structure.

[0147] Among them, the component connection structure is a structure connecting the first rotating component and the second rotating component. The component connection structure can enable the second rotating component to drive the simulated eyeball 100 to rotate around the second axis and drive the first rotating component to rotate around the second axis synchronously.

[0148] For example, the component connection structure is a rotating turntable connecting plate 420, which is connected to the upper end of the rotating state. The angle table 220 is fixed to the angle table lifting connecting plate 222 through the angle table fixing plate 221, and the angle table lifting connecting plate 222 is installed on the rotating turntable connecting plate 420. When the rotating turntable 410 rotates, the simulated eyeball 100, the angle table 220, the angle table fixing plate 221 and the angle table lifting connecting plate 222 are driven to rotate together through the rotating turntable connecting plate 420.

[0149] A specific embodiment is described below.

[0150] As shown in Figure 1, the simulated eyeball 100 is placed in the simulated eyeball fixing frame 310. The simulated eyeball 100 is directly connected to one end of the connecting rod 210, and the other end of the connecting rod 210 is connected to the angle platform 220. The angle platform 220 drives the simulated eyeball 100 to perform up and down swing motion with the center point of the simulated eyeball 100 as the center of the circle.

[0151] The corner platform fixing plate 221 is used to fix the corner platform 220 and connect the corner platform lifting connecting plate 222; the corner platform lifting connecting plate 222 connects the corner platform 220 and the rotating turntable connecting plate 420, which can be adjusted up and down.

[0152] The rotating turntable 410 provides rotational motion, and the center of rotation coincides with the center point of the simulated eyeball 100. The eyeball bracket 110 of the simulated eyeball 100 is installed on the rotating turntable connecting plate 420, driving the simulated eyeball 100 to rotate. The rotating turntable connecting plate 420 is also connected to the angle platform lifting connecting plate 222, driving the angle platform 220 to rotate together.

[0153] In this embodiment, the rotating turntable 410 drives the simulated eyeball 100 to rotate horizontally, and the angular position table 220 drives the simulated eyeball 100 to tilt up and down. The simulated eyeball 100 moves in three-dimensional space, realizing the real rotation effect of simulating the human eye. It can achieve 360-degree rotation in the horizontal direction and 90-degree arc movement in the vertical direction. The structure is simple, and the control parameters can be directly transmitted to the rotating components, which can simply and efficiently simulate the complex rotation of the human eye.

[0154] The following is a detailed introduction to the motion patterns that can be simulated by the eye simulation device.

[0155] In some embodiments, the simulated movement pattern of the eyeball 100 includes at least one of up and down movement, left and right movement, multi-line smooth scanning, saccade, gaze with small movement, convergence and divergence, and convergence and divergence.

[0156] For the up and down movement mode, the first rotating component drives the simulated eyeball 100 to rotate within a certain angle range in the vertical plane where the first axis is located with the center point of the simulated eyeball 100 as the center of the circle; for the left and right movement mode, the second rotating component drives the simulated eyeball 100 to rotate within a certain angle range around the second axis.

[0157] For a multi-line smooth scanning motion pattern, the second rotating component can drive the simulated eyeball 100 to rotate at a constant speed around the second axis within a certain angle range. At the end of each line, the first rotating component drives the simulated eyeball 100 to rotate within a certain angle range in the vertical plane where the first axis is located with the center point of the simulated eyeball 100 as the center of the circle, and then changes to the next line.

[0158] For the movement pattern of saccade, the rotation angle of the simulated eyeball 100 driven by the first rotating component and the second rotating component can be any angle.

[0159] For the gaze movement pattern with slight movement, the angle of rotation of the simulated eyeball 100 driven by the first rotating component and the second rotating component can be any angle. After the simulated eyeball 100 looks at a certain point, the first rotating component and the second rotating component drive the simulated eyeball 100 to move slightly.

[0160] It is understandable that the two movement modes of convergence and divergence can be realized by setting up two eye simulation devices.

[0161] For the convergence-divergence movement pattern, the simulated eyeballs 100 of the two devices rotate inwards, and the second rotating component drives the simulated eyeballs 100 to rotate around the second axis within a certain angle range.

[0162] For the convergence and divergence movement pattern, the simulated eyeballs 100 of the two devices rotate outward, and the second rotating component drives the simulated eyeballs 100 to rotate within a certain angle range around the second axis.

[0163] The eye simulation device of the disclosed embodiment drives the simulated eyeball 100 to rotate in both horizontal and vertical directions through the first rotating component and the second rotating component, thereby achieving the eyeball spatial rotation effect, and can simply and efficiently simulate the complex rotation of different types of human eyes.

[0164] The disclosed embodiment also provides an eye tracking method.

[0165] Among them, the eye tracking method can be applied to the above-mentioned eye simulation device, controlling the first rotating component and the second rotating component to drive the simulated eyeball 100 to perform pitch movement and horizontal rotation, thereby realizing the spatial rotation effect of the eyeball, and can simply and efficiently simulate the complex rotation of the human eye.

[0166] The eye tracking method provided in the embodiments of the present disclosure may be executed by an electronic device or a functional module or functional entity in the electronic device that can implement the eye tracking method. The electronic devices mentioned in the embodiments of the present disclosure include but are not limited to mobile phones, tablet computers, computers, cameras, and wearable devices. The eye tracking method provided in the embodiments of the present disclosure is described below using an electronic device as an example of the execution entity.

[0167] As shown in FIG6 , the eye tracking method includes: step 610 and step 620 .

[0168] Step 610: Obtain tracking point coordinate information of the target tracking point.

[0169] The target tracking point is the point that the eye simulation device needs to track and fixate on.

[0170] In this step, the tracking point coordinate information of the target tracking point is obtained. A coordinate system can be established with any point on the eye simulation device to obtain the tracking point coordinate information, or a coordinate system can be established with any point in space to obtain the tracking point coordinate information.

[0171] It can be understood that obtaining the tracking point coordinate information of the target tracking point is used to calculate the position difference between the simulated eyeball 100 and the target tracking point. In this step, the coordinate information of the simulated eyeball 100 can be obtained at the same time to calculate the position difference between the simulated eyeball 100 and the target tracking point.

[0172] In actual implementation, a coordinate system may be established with the center point of the simulated eyeball 100 , with the coordinate information of the simulated eyeball 100 as the origin coordinate information, and then the tracking point coordinate information of the target tracking point may be obtained.

[0173] Step 620: Based on the tracking point coordinate information, control at least one of the first rotating component and the second rotating component to rotate the simulated eyeball 100 so that the simulated eyeball 100 looks at the target tracking point.

[0174] In this embodiment, based on the tracking point coordinate information of the target tracking point, the control parameters required for the simulated eyeball 100 to rotate from the current position to the position of gazing at the target tracking point are calculated, and the first rotating component and the second rotating component are controlled to drive the simulated eyeball 100 to rotate according to their respective control parameters, so that the simulated eyeball 100 gazes at the target tracking point.

[0175] For example, the current pitch angle of the simulated eyeball 100 is 0 degrees. According to the tracking point coordinate information of the target tracking point, it is calculated that if the simulated eyeball 100 is to look at the target gaze point, the pitch angle of the simulated eyeball 100 needs to be adjusted to 30 degrees upward. The corresponding control parameters are directly transmitted to the first rotating component. The first rotating component drives the simulated eyeball 100 upward 30 degrees, and the second rotating component does not rotate, so that the simulated eyeball 100 looks at the target tracking point.

[0176] For another example, the current pitch angle and azimuth angle of the simulated eyeball 100 are both 0 degrees. According to the tracking point coordinate information of the target tracking point, it is calculated that if the simulated eyeball 100 is to look at the target gaze point, the azimuth angle of the simulated eyeball 100 needs to be adjusted to 20 degrees to the left and the pitch angle needs to be adjusted to 30 degrees upward. The control parameters of the two angle adjustments are transmitted to the first rotating component and the second rotating component respectively. The first rotating component drives the simulated eyeball 100 upward 30 degrees, and the second rotating component drives the simulated eyeball 100 to rotate 20 degrees, so that the simulated eyeball 100 looks at the target tracking point.

[0177] According to the eye tracking method provided by the embodiment of the present disclosure, by obtaining the tracking point coordinate information of the target tracking point, the first rotating component and the second rotating component are controlled to drive the simulated eyeball 100 to perform pitch movement and horizontal rotation, thereby realizing the spatial rotation effect of the eyeball. The structure is simple, and the control parameters can be directly transmitted to the rotating component, which can simply and efficiently simulate the complex rotation of the human eye.

[0178] In some embodiments, step 610, obtaining tracking point coordinate information of the target tracking point, may include:

[0179] Get the tracking point coordinate information entered by the user.

[0180] In this embodiment, the user inputs tracking point coordinate information, and the rotation of the first rotating component and the second rotating component is controlled according to the tracking point coordinate information input by the user, so that the simulated eyeball 100 gazes at the target tracking point.

[0181] In actual implementation, the user input corresponding to the tracking point coordinate information can be a touch operation, including but not limited to click operations, sliding operations and pressing operations of the eye simulation device or other terminal devices connected to the eye simulation device; it can also be physical button input or voice input.

[0182] Of course, in other embodiments, the user input corresponding to the tracking point coordinate information may also be in other forms, including but not limited to character input, etc., which can be determined according to actual needs and is not limited in this embodiment of the present disclosure.

[0183] In some embodiments, step 610, obtaining tracking point coordinate information of the target tracking point, may include:

[0184] Acquire the image of the target tracking point, perform image recognition, and obtain the tracking point coordinate information.

[0185] In this embodiment, the target tracking point is identified based on the image of the target tracking point to obtain the tracking point coordinate information of the target tracking point, thereby achieving full automation of simulating the eyeball 100 gazing at the target tracking point.

[0186] In some embodiments, step 620, controlling at least one of the first rotating component and the second rotating component to rotate the simulated eyeball 100 based on the tracking point coordinate information, may include:

[0187] Based on the tracking point coordinate information and in accordance with the target motion pattern, at least one of the first rotating component and the second rotating component is controlled to drive the simulated eyeball 100 to rotate.

[0188] Among them, the target movement mode is one of the movement modes that can be achieved by the simulated eyeball 100, and the movement modes of the simulated eyeball 100 include at least one of up and down movement, left and right movement, multi-line smooth scanning, saccade, gaze with small movement, convergence and divergence, and convergence and divergence.
