Description

Technical Field

[0001] This disclosure relates to the field of biomimetic robotics, and more specifically, to a simulated eye based on a microdisplay. Background Technology

[0002] With continuous breakthroughs in AI, robotics manufacturing, and new materials, the day when humans can create lifelike robots that mimic human behavior and expressions is just around the corner. In this process, the creation and simulation of eyes is a crucial step; one could even say that whether future robots can overcome the uncanny valley effect will largely depend on the effectiveness of eye simulation.

[0003] Currently, in the field of medical bionics, a representative approach to eye simulation and reconstruction involves constructing a retina-like prosthesis. This prosthesis uses photoelectric signal conversion to transmit captured signals to the optic nerve, which then relays the information to the brain for image processing. However, applying this approach to simulation production faces numerous technical challenges and is also extremely costly.

[0004] In the field of humanoid robot and doll manufacturing, the current method mainly involves using mechanical devices to control eye prostheses to mimic the activities of human eyes. A simpler approach even uses a glass sphere-shaped eye prosthesis. Obviously, since the pattern of the eye prosthesis is fixed, controlling its movement using mechanical devices cannot simulate all the real changes in the eye (such as changes in the pupil and iris when light or focal length changes), nor can it simulate real-time effects such as the eye's synchronous tracking of moving objects.

[0005] Overall, in the fields of humanoid robots, bionic robots, physical dolls, robotic pets, and bionic pets, current solutions for simulating eyes are not yet ideal. Utility Model Content

[0016] The angle formed by the first arm and the second arm at the connection point is an acute angle structure. The second arm extends in a direction inclined to the first arm and toward the plane where the end of the cover is located. The other end of the second arm is located near the plane where the end of the cover is located, so that the other end of the second arm can elastically apply a pressure toward the plane where the end of the cover is located.

[0040] In the following description, preferred embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein.

Therefore, the appearance of "in one embodiment" or "in some embodiments" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any way in one or more embodiments.

[0043] Furthermore, the terms "first," "second," etc., used in the specification and claims are used merely for clarity of description to distinguish various objects, and do not limit the size, quantity, or other order of the objects described. Directional terms indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are used solely for the purpose of describing this application, not to indicate or imply that the objects referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application.

[0044] The specific embodiments of this utility model are described in detail below. This utility model provides a simulated eye based on a micro-display screen. This simulated eye can be applied to the manufacturing fields of humanoid robots, bionic robots, physical dolls, robotic pets, and bionic pets. It can not only simulate the physical form of the eye, such as the transparent cornea and the protruding features of the eye, but also simulate the dynamic effects of the eye, such as displaying the iris pattern and color, pupil size, and simulating changes in eye movement.

[0045] As attached Figure 1 As shown, the simulated eye based on a micro-display according to this utility model includes at least one pair of curved bodies that approximate the physical shape of an eye, and an eye simulation unit 20. The curved bodies include a display screen, as shown in the attached figure. Figure 2 As shown, a screen display control unit 10 is provided on the back of the display screen. The screen display control unit 10 includes a light source, a driving circuit, a data input interface, and a packaging structure. The screen display control unit 10 is mainly responsible for converting the received signals into electrical signals that the screen can recognize, thereby accurately controlling the display state of each pixel.

[0046] The eye simulation unit 20 is used for data processing and simulation image generation. The eye simulation unit 20 is connected to the screen display control unit 10, enabling the display screen to show dynamic simulation effects of the eye, such as iris pattern and color, pupil size, and simulated eye movement changes. (See appendix) Figure 2 In use, the input interface of the screen display control unit 10 is connected to the display signal output interface of the eye simulation unit 20 via a data cable.

[0047] In one implementation, as shown in the appendix Figure 3 and 4 As shown, the display screen is a flat panel display screen 30. The shape of the flat panel display screen 30 is not limited to circular, elliptical, or rectangular shapes, and the surface of the display screen has no protrusions. See Appendix. Figure 1 , 5In addition to 6, the curved body also includes a cover 40 with a curved structure. The curvature of the cover 40 can be customized according to actual needs, and the ends of the cover 40 are not limited to circular, elliptical, or rectangular shapes. The cover 40 is detachably fixed to the outside of the flat panel display screen 30, and the main body of the cover 40 is made of transparent material. The transparent cover 40 with a curved structure simulates the physical shape of the eye, such as a transparent cornea and the protruding features of the eye.

[0048] The flat panel display 30 is either an LCD or an OLED display. The main body of the cover 40 is made of any one of the following materials: glass, crystal, or plastic.

[0049] As attached Figure 6 As shown, at least two elastic buckles 410 are provided at the ends of the cover 40 along its perimeter. Preferably, the two elastic buckles 410 are arranged opposite each other along the perimeter of the cover 40. The cover 40 is detachably fixed to the outside of the flat panel display screen 30 by the elastic buckles 410, thereby constructing a curved body that approximates the physical shape of the eye, so as to achieve the effect of simulating the physical shape of the eye.

[0050] Specifically, see Appendix Figure 6 The elastic buckle 410 includes a first arm 411 and a second arm 412. One end of the first arm 411 is fixed to the cover 40 by being implanted into the cover 40 or adhered to the surface of the cover 40. The first arm 411 extends in a direction perpendicular to the end plane of the cover 40 and away from the cover 40. The other end of the first arm 411 is connected to one end of the second arm 412.

[0051] The first arm 411 and the second arm 412 form an angled structure at the connection point. The angle is an acute angle. The second arm 412 extends in a direction that is inclined to the first arm 411 and toward the plane where the end of the cover 40 is located. The other end of the second arm 412 is located near the plane where the end of the cover 40 is located, so that the other end of the second arm 412 can apply a pressure facing the plane where the end of the cover 40 is located using elasticity. Thus, when the front of the flat panel display 30 is attached to the end of the cover 40, the elastic pressure of the elastic buckle 410 fixes the two together, thereby constructing a curved body that is similar to the physical shape of the eye, so as to achieve the effect of simulating the physical shape of the eye.

[0052] Preferably, the elastic buckle 410 is made of metal. The other end of the second arm 412 applies a pressure to the plane facing the end of the cover 40 by utilizing the elasticity of the metal, so that when the front of the flat panel display 30 is in contact with the end of the cover 40, the elastic pressure of the metal of the elastic buckle 410 will fix the two together.

[0053] In another implementation, as shown in the appendix Figure 7 and 8 As shown, a groove 420 is formed at the end of the cover 40 around the perimeter of the cover 40. The inner diameter of the groove 420 matches the outer diameter of the flat panel display 30, thereby fixing the flat panel display 30 and the cover 40 together through the groove 420, thus constructing a curved body that is similar to the physical shape of the eye, so as to achieve the effect of simulating the physical shape of the eye.

[0054] In another implementation, as shown in the appendix Figure 9 and 10 As shown, the display screen is a curved display screen 50, the curvature of which can be customized according to actual needs. The curved display screen 50 is an OLED display screen or a flexible display screen. The curved display screen 50 with a curved structure directly simulates the physical shape of the eye.

[0055] The eye simulation unit 20 includes hardware and software. The hardware (not shown in the attached diagram) includes a CPU, ROM, RAM, I / O ports, a counter, a communication interface, an analog-to-digital converter (ADC), an interrupt controller, and power management components. The communication interface includes a set of display signal output interfaces, such as a MIPI interface, which are used to connect to the screen display control unit 10 of the display screen.

[0056] In one embodiment, the communication interface further includes a set of serial port data transceiver modules. The serial port data transceiver modules can be used to connect to third-party devices or programs that use serial ports for communication. When using the serial port data transceiver modules, a serial communication cable is required for physical connection.

[0057] In another implementation, the communication interface also includes multiple digital sensor receiving modules, which are connected via I2C or SDI, connect to third-party sensors through physical cables, and collect sensor data.

[0058] In another implementation, the communication interface also includes a set of wireless Wi-Fi signal receiving modules. When using the wireless Wi-Fi signal receiving modules, data can be sent and received by setting a third-party IP address and establishing a communication connection with the third party via the wireless Wi-Fi signal.

[0059] In another implementation, the communication interface also includes a set of Bluetooth signal receiving modules. When using the Bluetooth signal receiving modules, data is sent and received by setting a third-party device ID and establishing a connection with the device via the Bluetooth wireless protocol.

[0060] Among them, as attached Figure 11As shown, the software of the eye simulation unit 20 includes an operating system, device drivers, and applications. The applications include a third-party data processing module, an eye dynamic simulation core algorithm module, and a display screen image correction algorithm module.

[0061] The third-party data processing module converts the received third-party data into a unified standard format based on the different third-party data receiving modules. For example, it converts data received from a serial port into parameters such as distance, orientation, object size, and light intensity.

[0062] The core algorithm module for dynamic eye simulation calculates display information such as sclera color, iris pattern color and style, pupil size, iris and pupil display position, and corneal reflectivity based on raw parameters input from a third-party data processing module or default simulation scene parameters, combined with distance, orientation, object size, light intensity, and pre-set biochemical parameters of the simulated object. Each frame of the displayed image contains this information; by continuously calculating the frame display information, the real-time effect of a simulated eye can be simulated.

[0063] The display screen image correction algorithm module is used to convert the frame display data calculated by the core algorithm of eye dynamic simulation into the final image to be displayed on the display screen, based on the pre-set transparent curved body or the curvature and reflection parameters of the flexible curved display screen 50, so that the simulated eye looks more natural and realistic.

[0064] In one embodiment, the software of the eye simulation unit 20 also includes other auxiliary modules, which include some basic program modules for maintaining the normal operation and maintenance management of the bionic eye, such as a default simulation library, a software update management module, and a display screen image correction parameter setting auxiliary module.

[0065] When simulating eyes, the aforementioned simulated eye, by default, displays a style without a fixed task, based on a pre-set simulation library in the eye simulation unit MCU. Examples include a blank stare mode, a gazing-in-the-distant mode, etc. When the eye simulation unit MCU is connected to an external input device (or data), it continuously controls the display of the eye's state in real time according to the input data or commands, simulating the current eye's activity state. Examples include adjusting the eyeball position, simulating the eye looking directly at someone being talked to, or simulating the eye tracking a moving object.

[0066] The simulated eye described above operates in two modes: a default mode and an external control mode. In the default mode, no interface with third-party devices or programs is required; the simulation automatically begins after the eye simulation unit MCU is powered on. In the external control mode, a connection is established using one of the communication connection methods described for the eye simulation unit MCU, and then the simulation begins once the eye simulation unit MCU and the connected external system are started.

[0067] The simulated eye based on a micro-display provided by this utility model has the advantages of good simulation effect, low cost, easy use and easy integration.

[0068] This simulated eye boasts excellent simulation effects, not only mimicking the physical appearance of the eye, such as the transparent cornea and convex features, but also simulating its dynamic effects, such as displaying iris pattern and color, pupil size, and simulating changes in eye movement.

[0069] This simulated eye separates the simulation of eye activity from external image recognition, motion capture, focus tracking, and other functional modules that require the support of sensors and specialized AI algorithms. It can be used independently for eye activity simulation, or it can be connected to third-party systems through the interface reserved in the eye simulation unit to further improve the simulation effect.

[0070] The scalability of this simulated eye is reflected in the fact that the application in the MCU of the eye simulation unit can be upgraded to meet different display needs, such as adding simulated blue eyes, brown eyes, or special state styles that need to be matched with certain emotions or expressions.

[0071] It should be noted that the features or combinations of features described above according to the present utility model, as well as the features and combinations of features mentioned and / or shown only in the accompanying drawings, can be used not only in the given combinations, but also in other combinations or individually, without departing from the scope of the present utility model.

[0072] This utility model has been described through the above embodiments. However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit this utility model to the scope of the described embodiments. Those skilled in the art should understand that many more changes and modifications can be made based on the teachings of this utility model, and all such changes and modifications fall within the protection scope of this utility model.
