[0002] The present disclosure relates to various methods and systems for diagnosing, monitoring, and treating adverse health conditions and disorders, including eye disorders and other disorders and disorders. [Background technology]

[0003] Ophthalmic instruments and treatments are routinely used by clinicians to diagnose and treat eye-related diseases. An example of a conventional ophthalmic device is shown in FIG. 1. As shown, the patient is seated in a specific seating position for the entire duration of the treatment, and the treatment can be administered continuously anywhere from a few seconds to a few minutes. This seating has been considered necessary to properly align the patient's eye with the ophthalmic device to perform measurements and / or ophthalmic treatments on the patient's eye. Summary of the Invention [Problem to be solved by the invention]

[0004] Unfortunately, ophthalmic devices tend to be large, bulky, and expensive devices, and are typically used exclusively in doctor's offices. Thus, patients must make an appointment with an optometrist and visit the doctor to receive a diagnosis or treatment. This can be a deterrent for many patients, and in some cases a long delay in visiting a doctor's office may pass until the disease worsens, necessitating more drastic therapy or treatment where the disease would have been more easily cured if the patient had been diagnosed or treated in a timely manner. Furthermore, the large and bulky nature of most ophthalmic devices forces patients to sit in uncomfortable positions for long periods of time, which in turn may actually increase the risk of misdiagnosis and patient error.

[0045] Various embodiments of the present invention relate to methods, systems, and articles of manufacture implementing a user-wearable health assessment system that can be used to provide health-related diagnosis, monitoring, and treatment to a user. Various objects, features, and advantages of the present invention are set forth in the detailed description, drawings, and claims.

[0046] Various embodiments are described in detail with reference to the drawings, which are provided as illustrative examples of the present invention so that those skilled in the art can practice the present invention. In particular, the following drawings and examples are not intended to limit the scope of the present invention. When a particular element of the present invention is implemented in part or in whole using known components (or methods or processes), only those parts of such known components (or methods or processes) that are necessary for understanding the present invention will be described, and detailed descriptions of other parts of such known components (or methods or processes) will be omitted so as not to obscure the present invention. Furthermore, various embodiments encompass current equivalents and future equivalents of the components referred to as examples in this specification.

[0047] Disclosed are methods and systems for diagnosing and / or treating a patient's health-threatening illnesses using a user-wearable health diagnostic system, such as a user-wearable ophthalmic device, which interacts with the user's eye. In one or more embodiments, the device can be a head-mounted system capable of implementing one or more diagnostic or treatment regimens. In some other embodiments, the device can be stationary (e.g., stationary in a doctor's office). In one or more embodiments, the device can be an augmented reality system that advantageously combines a number of augmented reality (AR) and / or virtual reality (VR) technologies for health care or eye treatment purposes. In some other embodiments, the device can be worn by a clinician for diagnosis and / or simulation and training. Although various embodiments described below describe a new paradigm of health systems in conjunction with an AR system, it should be understood that the treatment methods disclosed herein can be used independently of any existing and / or known AR system. Thus, the examples described below are merely illustrative and should not be read as being limited to AR systems.

[0048] As described above, embodiments of the present invention present a new paradigm in which a user-wearable health diagnostic or health care treatment system (herein abbreviated as health system), e.g., an ophthalmic instrument, is worn by a patient and can be programmed with one or more applications specific to various health care related diseases, e.g., eye related diseases. In some embodiments, diagnosis and / or treatment may be performed by optical structures, mechanical structures, processing algorithms, or any combination of the above elements. In some other embodiments, the patient-worn health system may be accompanied by sensing and / or stimulation capabilities to enhance treatment or diagnosis. In some embodiments, a head-mounted augmented reality system may be used to perform various health care related measurements, assessments, diagnoses, or treatments, e.g., ophthalmic measurements, assessments, diagnoses, or treatments.

[0049] When the head mounted augmented reality display system interacts with the user's eye, many applications can be envisioned for ophthalmology-related diagnosis and treatment. In addition, many other applications in non-visual diagnosis and treatment can be envisioned as well. Thus, the disclosure presented herein is not limited to eye diagnosis, monitoring, and treatment. The embodiments disclosed herein can also be applied to diagnose, monitor, and treat other areas of a user's health, including, but not limited to, the user's cardiovascular and neurological health.

[0050] Many embodiments of the health system are described in relation to various eye-related disorders and diseases. Before describing the various embodiments of the health system in detail, a brief description of the biological mechanisms of the human eye will be provided below to provide an understanding of common disease conditions that may affect a patient.

[0051] Referring to FIG. 2, a simplified cross-section of the human eye is shown featuring the cornea (42), iris (44), lens or "crystalline lens" (46), sclera (48), choroid layer (50), macula (52), retina (54), and optic nerve pathways (56) leading to the brain. The macula is the center of the retina and is used for seeing moderately fine features; at the center of the macula is a portion of the retina labeled the "fovea," which is used for seeing the finest features and contains more photoreceptors (approximately 120 cone photoreceptors per diopter) than any other part of the retina. The human visual system is not a passive sensor system; it is configured to actively scan the environment. In a manner much like the way a flatbed scanner is used to capture an image, or a finger is used to read Braille from paper, the eye's photoreceptors are activated in response to changes in stimuli rather than constantly responding to a constant stimulus state.

[0052] Thus, motion is required to present the photoreceptor information to the brain (such as the movement of a linear scanner array across a piece of paper in a flatbed scanner, or the movement of a finger across a Braille word imprinted on a piece of paper). Indeed, experiments with substances such as cobra venom that are used to paralyze the eye muscles have shown that human subjects experience blindness when viewing a static scene in an open-eyed position with the eyes paralyzed by snake venom. In other words, in the absence of a change in stimulus, the photoreceptors have no input to the brain, and so blindness is experienced. This is thought to be at least in part due to the fact that normal human eyes have been observed to sway or wobble back and forth while moving side to side in a phenomenon called "microsaccades."

[0053] As explained above, the fovea of ​​the retina contains the greatest density of photoreceptors, and humans usually perceive it as having high-resolution visualization capabilities across the entire visual field, but humans usually only have a small high-resolution center, so humans mechanically move their eyes repeatedly while permanently storing high-resolution information captured at the fovea at the most recent time. In a fairly similar manner, the eye's focal length control mechanism (the ciliary muscle is operatively coupled to the lens such that ciliary relaxation causes the taut ciliary connective fibers to flatten the lens for more distant focal lengths; ciliary contraction relaxes the ciliary connective fibers, allowing the lens to adopt a rounder geometric shape corresponding to closer focal lengths) swings back and forth by about 1 / 4 to 1 / 2 diopters, periodically inducing a small phenomenon called "refractive blur" both near and far from the target focal length; this is utilized by the brain's focus control circuit as a periodic negative feedback that constantly corrects course and helps to keep the retinal image of a fixed object in near focus.

[0054] The visual center of the brain also obtains valuable perceptual information based on the movement of the eyes and their components relative to each other. The convergence movement of the two eyes relative to each other (i.e., moving the pupils toward or away from each other to converge and fixate on an object) is closely related to the focusing action (or "accommodation") of the eye's lenses. Under normal conditions, changing or adjusting the focus of the eye's lenses to focus on an object and at a different distance automatically results in a change in convergence to match the same distance according to a relationship known as the "accommodation-vergence reflex". Similarly, a change in convergence causes a change in accommodation to match under normal conditions. As with most conventional stereoscopic AR or VR configurations, acting against this reflex is known to result in eye muscle fatigue, headaches, or other forms of discomfort for the user.

[0055] Head movements that accommodate the eyes also have a significant impact on object visualization. Humans move their heads to visualize the human ground; humans often enter into a fairly constant state of changing head position and head orientation relative to the object of interest. Furthermore, most humans choose to move their heads when it is necessary to move the human line of sight more than about 20 degrees off center to focus on a particular object (i.e., humans do not typically like to see things "out of the corner of the eye"). Humans also typically move or shift their heads in relation to sound over a certain range to improve the capture of sound signals, taking advantage of the shape of the ears relative to the head. The human visual system can derive powerful depth cues from information called "head motion parallax," which describes the relative motion of objects at different distances as a function of head movement and eye convergence distance (i.e., if a person moves their head from side to side to gaze at an object, objects located farther away from the object will move in the same direction as the head; objects located in front of the object will move in the opposite direction to the head; these are very salient cues when things are spatially located in the environment relative to the person - perhaps as powerful as stereopsis). Head movement is of course also used to view objects above ground.

[0056] Furthermore, head and eye movements keep object image information approximately centered on the retina by coordinating with what is called the "vestibulo-ocular reflex" that stabilizes image information on the retina during head rotation. As the head rotates, the eyes rotate reflexively and proportionally in opposite directions to keep the object fixed on a stable gaze. As a result of this complementary relationship, many people can read a book while shaking their head back and forth (interestingly, the same is not usually true if the head is kept nearly stationary and the book is moved back and forth at the same speed - the person is unlikely to be able to read a moving book; the vestibulo-ocular reflex is a coordination of head and eye movements, and is not usually utilized with hand movements). This paradigm is crucial for patient-worn health systems, because it allows the user's head movements to be relatively directly related to eye movements, and the system is preferably ready to operate with this relationship intact. Therefore, when designing a patient-worn or stationary display-based health system, the characteristics of the human eye, and possibly the limitations of the human eye, are taken into account to provide meaningful virtual reality content so that the virtual reality content works with the natural mechanics of the eye, rather than causing stress. Furthermore, in the context of health-related applications of an augmented reality display system, this can provide various advantages, as disclosed herein. As described above, the display of the health system can be implemented independently of an augmented reality (AR) system, but many of the following embodiments are described only for purposes of illustration in conjunction with an AR system.

[0057] 3A-3D, some general component options are illustrated. While the embodiments of Figures 3A-3D show a head mounted display, it will be appreciated that in some embodiments the same components may also be incorporated into a stationary wellness system.

[0058] As shown in FIG. 3A, a user (60) is shown wearing a patient-worn ophthalmic device that includes a frame (64) structure connected to a display system (62) that is placed in front of the user's eye. Depending on the application of the health system, the frame 64 can be connected to multiple ophthalmic-specific measurement subsystems. Some embodiments can be built for one or more ophthalmic applications, while other embodiments can be general-purpose AR systems that can also be applied to ophthalmic applications. In any case, the following sections describe possible components of a health system or an AR system used for ophthalmic equipment and / or eye treatment.

[0059] In one or more embodiments, the health system is worn by a patient or user. In some other embodiments, the health system may be worn by another person, such as a doctor or clinician, who may use the health system to perform a series of diagnostic tests and / or treatment protocols on a patient other than the wearer of the system. It should be appreciated that any of the following applications may also be used by other persons wearing the health system to perform diagnostic tests and / or treatment protocols on a patient.

[0060] A speaker (66) may be connected to the frame (64) in the configuration shown and may be positioned adjacent the user's ear canal (in one embodiment, another speaker, not shown, is positioned adjacent the user's other ear canal to provide stereo / shaped sound control). A microphone (55) may also be connected to the frame to detect sounds from the user or the world. In some embodiments, another microphone (not shown) may be provided, for example connected to the frame (64) on the right hand side of the user. In one or more embodiments, the wellness system can have a display (62) operably connected (68), for example via a wired lead or a wireless connection, to a local processing and data module (70) that is mounted to the frame (64) in a variety of configurations, for example, secured to the frame (64), secured to a helmet or hat (80) as illustrated in the embodiment of FIG. 3B, embedded in headphones, removably attached to the torso (82) of the user (60) in a backpack-type configuration as illustrated in the embodiment of FIG. 3C, or removably attached to the hips (84) of the user (60) in a belt-type configuration as illustrated in the embodiment of FIG. 3D.

[0061] The local processing and data module (70) may include a power-efficient processing unit or controller and digital memory, such as flash memory, utilizing both of these components to facilitate processing, caching, and storage of data that a) is collected from sensors, such as imaging devices (such as cameras), microphones, inertial measurement units, accelerometers, compasses, GPS units, radios, and / or gyros, which may be operably connected to the frame (64), and / or b) after such processing or retrieval, is acquired and / or processed using a remote processing module (72) and / or a remote data repository (74) for possible delivery to the display system (62). The local processing and data module (70) may be operably connected (76, 78) to the remote processing module (72) and remote data repository (74), for example, via a wired or wireless communication link, such that the remote modules (72, 74) may be operably connected to each other and utilized as resources for the local processing and data module (70).

[0062] In some embodiments, the remote processing module (72) may comprise one or more relatively sophisticated processing devices or controllers configured to analyze and process the data and / or image information. In some embodiments, the remote data repository (74) may comprise relatively large digital data storage devices available in a "cloud" resource configuration over the Internet or other network configuration. In some embodiments, all data is stored and all calculations are performed on the local processing and data modules, allowing any remote module to be used completely autonomously.

[0063] Advantageously, a health system similar to the system described in Figures 3A-3D (or an AR system with ophthalmic applications) can have unique access to the user's eyes and head. If the health system interacts with the user's eyes to enable the user to perceive 3D virtual content, and in many embodiments tracks various biometrics related to the user's eyes (such as eye convergence, eye movement, retinal structure, anterior and posterior eye shapes, eye movement patterns, etc.), the resulting tracking data can be advantageously used in health-related applications, as described in more detail herein. This unprecedented access to the user's eyes can be utilized in a variety of health management applications. Depending on the type of health-impairing disease, the health system can image, detect (including measure) and / or stimulate the user's eyes to diagnose and / or treat the disease.

[0064] In one or more embodiments, the augmented reality display system can be used as a patient-worn or user-worn ophthalmic device. Ophthalmic equipment can be used by clinicians to view the inside of a patient's eye to perform medical procedures and / or perform eye examinations on a user. Traditionally, ophthalmic devices are large, bulky, stationary devices that often require a patient to travel to a doctor's clinic where the clinician or doctor performs eye-related examinations on the patient. Typically, the patient is restrained by the ophthalmic instrument (e.g., resting their chin on the chin rest of the ophthalmic device, pushing their head forward, etc.) until the clinician completes a series of examinations. Thus, current approaches have many limitations.

[0065] In addition to using heavy and bulky devices for testing, the conventional approach requires doctor supervision, and the patient must repeatedly return to the clinician's clinic for further testing / progress analysis, and must assume an uncomfortable or constrained position for a long period of time. Furthermore, if the patient is only on the ophthalmic device for a short period of time, the amount of data that the clinician can collect to diagnose or treat the patient is limited. Furthermore, the conventional approach does not take into account the user's behavior and dynamic changes in the user's posture. Many tests performed with the conventional approach generally require the user to be constrained in a specific stationary position. However, when a user is subjected to a visual field test and has a limited gaze range, the user moves the user's head and eyes, which generates noise and, in some cases, leads to inaccurate test results.

[0066] In one or more embodiments, a head-mounted health management (e.g., ophthalmic) device similar to the device shown in FIG. 3A-3D may be used by a patient to track data, identify and cure one or more eye-related diseases, and / or help prevent other health problems. In one or more embodiments, the AR display system may be used as a head-mounted health management (e.g., ophthalmic) device. It will be appreciated that many of the embodiments described below may be implemented as head-mounted embodiments, while other embodiments may be implemented as stationary devices. Furthermore, some embodiments may implement systems and methods using AR technology to diagnose, monitor, and / or treat under medical supervision (e.g., medical safety issues, regulatory issues, etc.), while other embodiments may be implemented as described herein to perform self-diagnosis and / or monitoring using a head-mounted health management device or AR device, or as part of a treatment protocol for a particular disease. For purposes of illustration, the present disclosure focuses primarily on head-mounted health management devices, e.g., wellness systems, and in particular AR devices, but it should be understood that the same principles can be applied to non-head-mounted embodiments.

[0067] In one or more embodiments, the AR display device can be used as a patient-worn health management device, for example, a patient-worn health system. The device can typically be worn on a specific user's head, with the optics aligned to the user's eyes. These configuration steps can be used to help ensure that the user receives an optimal augmented reality experience without causing physiological side effects such as headaches, nausea, discomfort, etc. Thus, in one or more embodiments, the patient-worn health system can be configured (physically and digitally) for each individual user, and a set of programs can be specifically calibrated for the user. In other scenarios, a loose AR device can be used comfortably by a wide variety of users. For example, in some embodiments, the patient-worn health system knows one or more of the following: the distance between the user's eyes, the distance of the head-mounted display and the user's eyes, the curvature of the user's forehead, the distance to the ears, or the height of the nose bridge for proper fit. All of these measurements can be used to provide the correct head-mounted display system to a specific user. In some other embodiments, such measurements are not necessary to perform the eye examination function.

[0068] For example, referring to FIG. 4A-4D, the health system can be customized for each user. As shown in FIG. 4A, in one or more embodiments, the user's head shape 402 can be taken into consideration when wearing the head-mounted patient-worn health system. Similarly, as shown in FIG. 4B, the ophthalmic optics 404 (e.g., optics, structure of optics, etc.) can be rotated or adjusted for user comfort in both horizontal and vertical directions, or rotated for user comfort. In one or more embodiments, as shown in FIG. 4C, the head rotation reference point set with respect to the user's head can be adjusted based on the structure of the user's head. Similarly, as shown in FIG. 4D, the interpupillary distance (IPD) (i.e., the distance between the user's eyes) can be corrected.

[0069] In the context of a patient-worn health system, this form of head-mounted device can be advantageous because the system already maintains a set of measurements of the user's anatomical characteristics (e.g., size, interocular distance, etc.) and other data that can be used to treat and diagnose the patient.

[0070] In addition to various measurements and calibrations performed on the user, the patient-worn health system can be configured to track a set of biometric data on the user to identify the patient and to perform secure communication. For example, the system can perform iris recognition and / or retina matching to identify the patient, track eye movement tracking, eye movement patterns, blink patterns, eye convergence movements, fatigue parameters, eye color changes, focal length changes, and many other parameters that can be used to provide the user with an optical augmented reality experience. For AR devices used in healthcare applications, it can be understood that some of the above-described forms can be part of widely available AR devices, and other features can be incorporated into specific healthcare-related applications.

[0071] Next, referring to FIG. 5, various components of an exemplary patient-worn health management display device will be described. It should be understood that other embodiments may have additional or fewer components depending on the application (e.g., a particular diagnostic tool) for which the system is used. However, FIG. 5 provides a basic idea of ​​some of the various components and types of biometric data that can be collected and stored using a patient-worn health system or AR device. FIG. 5 illustrates a simplified head-worn health system 62 on the right side in block diagram form.

[0072] Referring to FIG. 5, one embodiment of a suitable user display device (62) is shown, which includes a display lens (64) that can be mounted on the user's head or eyes via a housing or in a frame (108) corresponding to the frame (64) (FIGS. 3A-3D). The display lens (106) is disposed in front of the user's eyes (20) via the housing (108) and can include one or more transparent mirrors configured to bounce the projected light (38) back to the eyes (20) to facilitate beam shaping and allow transmission of at least some rays of light from the local environment. As shown, two wide-field machine vision cameras (16) are connected to the housing (108) to image the environment around the user; in one embodiment, the cameras (16) are dual capture visible / non-visible (e.g., infrared) cameras.

[0073] Continuing with reference to FIG. 5, a pair of light projection modules are shown with viewing mirrors and optics configured to project light (38) into the eyes (20) and wavefront shaping (i.e., for depth adjustment) by a scanning laser. The illustrated embodiment also includes two miniature infrared cameras (24) paired with infrared light sources (26, such as light emitting diodes "LEDs") configured to track the user's eyes (20) to support rendering and user input. The system (62) further features a sensor assembly (39) that includes X, Y, and Z axis accelerometer functionality as well as magnetic compass and X, Y, and Z axis gyro functionality, thereby enabling data to be provided at a relatively high frequency, such as preferably 200 Hz. The depicted system also includes a head pose processing unit (36), such as an ASIC (application specific integrated circuit), FPGA (field programmable gate array), and / or ARM processing unit (advanced reduced instruction set machine), which can be configured to calculate real-time, or near real-time, user head pose from the wide FOV image information output by the imaging device (16).

[0074] Also shown is a processing unit (32) configured to perform digital and / or analog processing to derive attitude based on gyro, compass, and / or accelerometer data from the sensor assembly (39). The illustrated embodiment also features a GPS (37, Global Positioning Satellite) subsystem to assist with attitude and positioning analysis. The GPS can also provide remote (e.g., cloud-based) information about the user's environment. This information can be used for diagnostic purposes. For example, if the user is in an area with a high density of pollen in the surrounding atmosphere, this information can be useful for diagnosing and / or treating a particular illness. Or, in another example, information about air pollution in a particular atmosphere can be advantageously used when considering treatment options for a particular user. Other types of information (e.g., pollen counts, pollution, demographics, environmental toxins, indoor climate and air quality conditions, lifestyle statistics, proximity to medical facilities, etc.) can be used for one or more applications as well.

[0075] The illustrated embodiment may also include a rendering engine (34), which may feature hardware that executes software programs configured to enable rendering of information about the location of the user to facilitate the operation of the scanner and imaging of the inside of the user's eyes so that the user can view the ground. The rendering engine (34) is operably connected (105, 94, 100 / 102, 104; i.e., via wired or wireless connections) to the sensor pose processor (32), image pose processor (36), eye tracking camera (24), and projection subsystem (18) so that the rendered light is projected using the scanning laser device (18) in a manner similar to a retinal scanning display. The wavefront of the projected light beam (38) is curved or focused to match the desired focal length of the projected light.

[0076] A camera (24) (e.g., a miniature infrared camera) may be used to track the eyes to support rendering and user input (if the user is looking to see what depth he or she is focusing at; eye convergence may be used to estimate focal depth, as described below). A GPS (37), gyro, compass, and accelerometer (39) may be used to provide a coarse estimate and / or fast pose estimation. The camera (16) images and pose may be used in conjunction with data from associated cloud computing resources to create a ground map of the scene to share the user view with others and / or virtual or augmented reality communities and / or medical institutions. In one or more embodiments, the camera (16) may be used to analyze the food, drugs, nutrients, and toxins consumed by the user as part of a comprehensive health care and / or wellness or health care monitoring system.

[0077] Continuing to refer to FIG. 5, the display device (62) can include a drug delivery module (21) for delivering a drug to a user. The drug delivery module (21) can include one or more outlets (22) and at least one drug container (23), which can be a reservoir that contains a drug and releases it through the outlet (22). The outlet (22) can be connected to the container (23) through one or more flow paths (22a), which can deliver a drug (e.g., a liquid or gas) from the container (23) to the outlet (22). In some embodiments, the outlet (22) can simply be an opening in the frame (108), or can be a nozzle attached to or integral with the frame (108). In some embodiments, the nozzle can be a sprayer. In some embodiments, the flow paths (22a) are formed by openings in the frame (108) and / or tubing.

[0078] In one or more embodiments, the display device can include a light emitting module (27) that selectively projects light onto the wearer, such as to treat the wearer's eyes according to a treatment protocol. The light emitting module (27) can include light sources, including light emitters that emit polychromatic polarized light, lasers, light emitting diodes, fluorescent lamps, dichroic lamps, full spectrum light sources, and the like. In some embodiments, one light emitting module (27) can be provided for each eye. In some other embodiments, the display device can include multiple light emitting modules (27), with each eye having at least one light emitting module configured to direct light to that eye.

[0079] While most of the hardware of the display system 62, the features of which are depicted in Figure 5, are shown directly connected to the display 106 and the housing 108 adjacent the user's eye 20, the illustrated hardware components may be mounted on or contained within other components, such as a belt-mounted member, as shown in Figure 3D, for example. Additionally, as described herein, a number of sensors and other functional modules are illustrated grouped together for clarity of illustration and description. However, it will be understood that some embodiments may include only one or only a portion of these sensors and / or modules.

[0080] In one embodiment, all of the components of system (62) featured in Figure 5 are directly connected to the display housing (108), with the exception of the image pose processor (36), the sensor pose processor (32), and the rendering engine (34), and communication between the latter three components and the remaining components of the system may be by wireless communication, such as ultra-wideband communication, or by wired communication. The illustrated housing (108) is preferably mountable and wearable on the head of a user. The system may also feature speakers, such as speakers that may be inserted into the user's ears and utilized to project sound to the user (e.g., speaker (66), Figures 3A-3D).

[0081] With regard to projecting light 38 into the user's eye 20, in some embodiments, a camera 24 can be used to measure where the center of the user's eye 20 is geometrically close, which typically corresponds to the focal position or "focal depth" of the eye 20. The three-dimensional surface of where the eye is close is called the "horopter." The focal distance can have a finite number of different depths, or it can vary infinitely. Light projected from the convergence distance appears to be in focus on the test eye 20, with light in front of or behind the convergence distance being blurred.

[0082] Further, without being bound by theory, it has been found that spatially coherent light having a beam diameter of less than about 0.7 millimeters is accurately resolved by the human eye, regardless of where the eye is focused. Given this understanding, to create the proper illusion of depth of focus, eye convergence can be tracked by the camera (24) and the rendering engine (34) and projection subsystem (18) can be utilized to focus all objects on or near the horopter, and all other objects can be blurred to various degrees of focus (i.e., with intentional blur). Preferably, the system (62) renders to the user at a frame rate of about 60 frames per second or greater. As explained above, the camera (24) can be utilized to perform eye tracking, and software can be configured to detect convergence geometry as well as focus cues to serve as user input. Preferably, such a display system is configured with brightness and contrast suitable for daytime or nighttime use.

[0083] In some embodiments, the display system preferably has a latency of less than about 20 milliseconds when aligning a viewed object, an angular alignment accuracy of less than about 0.1 degrees, and an angular resolution of about 1 minute, which are believed to be close to the limits of the human eye, without being bound by theory. The display system 62 may be integrated with a location system that may include a GPS element, optical tracking, a compass, an accelerometer, and / or other data sources to aid in knowing position and orientation; the location information may be utilized to facilitate accurate rendering of a user's view of an associated ground surface (e.g., such information may facilitate recognition of where a user is located relative to the real ground surface through eye wear). Having described the general components of some embodiments of a user-wearable health diagnostic system, e.g., an ophthalmic system, further components and / or features related to health care and diagnosis are described below. It should be understood that some of the features described below are common to various embodiments of user-wearable health assessment systems or many embodiments of AR systems used for health, while other features require additional components or a fewer number of components to perform health assessment and treatment.

[0084] In some embodiments, the user-wearable health examination system is configured to display one or more virtual images based on the focus of the user's eyes. Unlike conventional 3D display methods that force the user to focus on where the image is projected, in some embodiments, the user-wearable health examination system is configured to automatically change the focus of the projected virtual content to allow the user to more comfortably view one or more images presented to the user. For example, if the current focus of the user's eyes is 1m, the image is projected to match the user's focus. Alternatively, if the user shifts the focus to 3m, the image is projected to match the new focus. In this way, rather than forcing the user to adjust to a predetermined focus, the user-wearable health examination system or AR display system of some embodiments allows the user's eyes to function in a more natural way.

[0085] Such a user-wearable health assessment system can eliminate or reduce the occurrence of eye strain, headaches, and other physiological symptoms typically observed with virtual reality devices. To achieve this, various embodiments of the patient-wearable health system are configured to project virtual images at various focal distances via one or more variable focus elements (VFEs). In one or more embodiments, the 3D perception can be achieved by a multi-plane focus system that projects the image onto a fixed focal plane away from the user. Other embodiments use a variable focal plane that moves the focal plane back and forth in the z-direction to match the user's current focus state.

[0086] In both the multi-plane focus system and the variable plane focus system, the patient-worn health system can use eye tracking to determine the convergence of the user's eyes, learn the user's current focus, and project the image at the learned focus. In other embodiments, the user-wearable health examination system includes a light modulator that projects light beams of various focuses via a fiber scanner or other light emitting source in a raster pattern across the retina in a diopter variable manner. In this manner, the health system display's ability to project images at various focal lengths not only facilitates adjustments for the patient to view objects in 3D, but can also be used to correct ocular abnormalities in the patient, as described in more detail below. In some other embodiments, the spatial light modulator can project the image to the user through various optical components. For example, as described in more detail below, the spatial light modulator can project the image to one or more waveguides, which then transmit the image to the user.

[0087] Next, referring to FIG. 6, an exemplary process flow for projecting one or more virtual images based on a user's accommodation reflex will be briefly described. At 602, the system can determine the convergence of the user's eyes via an eye-tracking system. At 604, the system can estimate the current focus of the user's eyes based on the determined convergence. It should be understood that other embodiments of the AR system (or wellness system) do not necessarily utilize eye tracking, but can sequentially display images at a rapid rate to provide a 3D perception. Thus, the process flow of FIG. 6 should not be considered limiting, but is presented for illustrative purposes only.

[0088] If the health system uses a multiple visual depth plane display system (i.e., light is projected onto multiple fixed visual depth planes), the system can determine 608 a focal plane that is closest to the estimated focus based on eye convergence and accommodation. It will be appreciated that accommodation can be measured, for example, by using an autorefractor or other device compatible with the display system. At 610, the health system can project at least a portion of the image onto the determined focal plane.

[0089] If the wellness system utilizes a variable depth plane display system (i.e., one or more focal planes onto which the virtual content is projected can be moved back and forth in the z-direction), then at 612 the focus of the system is changed via the VFE to match the estimated focus. At 614, the wellness system can project at least a portion of the image onto the focal plane. Similarly, other embodiments of the wellness system can use other 3D image generation methods to provide a comfortable, adjustable, reflective projection of the virtual object to the user.

[0090] In some embodiments, the image is displayed by projecting light associated with the virtual image into the user's eye, although any wavelength of light may be similarly projected into the user's eye. In addition to visible light, infrared light or other forms of light may also be similarly projected using the patient-worn health system. This form of patient-worn health system may also be similarly used to treat health conditions, as described below.

[0091] Also, while various embodiments are described in which light is projected into the user's eye, it should be understood that in one or more embodiments, the health system can also receive light emitted from the user's eye. In one or more embodiments, the light source of the health system can be a fiber scanning device (FSD) that projects light into the user's eye in various patterns (e.g., raster scan, spiral scan, Lissajous scan, etc.). Similarly, other light sources (e.g., OLED, DLP, LCD, etc.) can be used in other embodiments of the health system as well. Besides projecting light, the FSD can receive the emitted light in one or more embodiments. The same fiber that projects the light can be used to receive the light. In this mode, the health system can function as a multi-dimensional depth scanner that multiplexes the modulated light waves output with the light waves that are detected or captured. In some embodiments, the fiber scanner can be used in conjunction with a camera (24) (FIG. 5) or in place of the camera (24) to, for example, track or image the user's eye. In one or more embodiments, rather than the FSD being configured to receive light, the health system may have a separate light receiving element that receives light emitted from the user's eye and collects data related to the emitted light. Thus, in one or more embodiments, the emitted light and corresponding data may be analyzed to diagnose or treat abnormalities, as described below.

[0092] Various details of the fiber scanning display device will now be described with reference to Figures 28A-28C. Referring to Figure 28A, a gradient index lens or "GRIN" lens 354 is shown fused to the end face of a single mode optical fiber. An actuator 350 (such as a piezoelectric actuator) is coupled to the fiber 352 and can be used to scan the fiber tip.

[0093] 28B, the multicore fiber 362 can be scanned (e.g., by a piezoelectric actuator 368) to generate a series of beamlets with multiple angles of incidence and intersection points, which can be relayed to the eye 58 via a waveguide (370). Thus, in one embodiment, a collimated light field image can be injected into the waveguide, and the light field representation can be converted to be directly visible to the human eye, without the need for any additional refocusing optics.

[0094] Display systems have been built in the past that use eye tracking or gaze tracking as input and conserve computational resources by simply providing a high-resolution rendering corresponding to where the person is currently looking, while a lower-resolution rendering is applied to the remainder of the retina; the position of the high-resolution portion relative to the low-resolution portion can dynamically follow the tracking gaze position in such a configuration, which can be described as a "foveated display."

[0095] An improved version of such a configuration can include a scanning fiber display with a pattern pitch that can dynamically follow the gaze of the tracked eye. For example, as shown in Fig. 28C, when a typical scanning fiber display operates in a spiral pattern (the leftmost portion 510 of the image in Fig. 28C shows the spiral motion pattern of the scanning multi-core fiber 514; the rightmost portion 512 of the image in Fig. 28C shows the spiral motion pattern of the scanning single fiber 516 for comparison), the constant pattern pitch provides a uniform display resolution.

[0096] It will be appreciated that in addition to displaying an image or acting as an imaging device, the display system can provide illumination to image the eye or tissues around the eye. In one or more embodiments, the health system includes an optical scanning or detection module that allows the device to scan the front and interior of the eye using known visible and non-visible light spectrum techniques, which may include visible light imaging devices, light refraction, optical coherence tomography (OCT), and light field microscopy (LFM). In one or more embodiments, the ophthalmic system can further include a light field imaging module that simultaneously captures multiple images of the eye at different focal lengths. It will be appreciated that the display, e.g., the FSD, is advantageously configured to allow multiple frequencies of light to be emitted from the display simultaneously. For example, the FSD can include a single-core fiber, or a multi-core fiber that is advantageously capable of emitting multiple frequencies of light simultaneously.

[0097] In health care and diagnostic situations, the type, frequency, color scheme, arrangement, etc. of one or more images presented to a user can be advantageously manipulated to diagnose and treat one or more disorders. For example, certain diseases require strengthening one eye relative to the other. To this end, treatment protocols can be envisioned that "train" the weaker eye, for example by providing stronger stimulation to the weaker eye relative to the stronger eye. Or, in another example, certain parts of the retina may have reduced sensitivity due to macular degeneration; to address this, images can be modulated or reformatted and projected to the periphery of the retina to correct the user's reduced visual function. Thus, as described in more detail below, the health system's ability to modulate multiple parameters associated with virtual image projection can be used to diagnose and / or treat certain health abnormalities.

[0098] Furthermore, using the various principles outlined above, the health system can be designed to perform diagnosis using a stimulus-response measurement analysis process. Devices such as these devices can be used by a clinician, or in other embodiments, a particular disease can simply be "diagnosed" by the patient, or the patient can recognize it as a symptom (e.g., eye muscle fatigue, dry eye, high blood pressure, onset of stroke, or attack). This allows the user to take greater active control over his / her health, and to prevent the onset of disease by proactively treating the disease at the onset of certain symptoms. Such diagnosis can be performed by analyzing data acquired simultaneously with one or more tracked biometric parameters and historical data related to environmental changes. In one or more embodiments, the health system can also be configured to provide information clues to alert the user and / or a doctor or others, or to facilitate other response measures.

[0099] It should be appreciated that the health system can be configured to be autonomous (i.e., provide results directly to a user or other person or entity without input or control by a clinician or other person) or semi-autonomous (subject to some degree of input or control by a clinician or other person). In other embodiments, the health system can be fully controlled by a clinician or other person, for example in a networked or remote (cloud-based) manner (e.g., with software control of the health system diagnosing, monitoring, or treating the user), or with the health system worn by a doctor to test the patient.

[0100] 5, in one or more embodiments, the wellness system may be designed with multiple additional health-related sensors. The wellness system may include a number of sensors (e.g., acceleration sensors, gyroscopes, temperature sensors, pressure sensors, light sensors, non-invasive blood glucose sensors, ETCO2, EEG, and / or other physiological sensors) that monitor one or more physiological responses of the user.

[0101] As described herein, in one or more embodiments, the health system includes an eye tracking module that can be configured to determine the convergence of the user's eyes to determine proper normal focusing when projecting one or more virtual images, and can be further configured to track one or more eye-related parameters (e.g., eye position, eye movement, eye patterns, etc.). This data can be used for several health-related diagnostic and treatment applications, as described below.

[0102] As will be apparent from the description herein, the health system can be used for diagnosis, monitoring, and treatment, which can include eye-related diagnosis, monitoring, and treatment. In such eye-related applications, the health system can be referred to as an ophthalmic system. Also, as will be apparent from the description herein, the user (or wearer) of the device can be referred to as a patient when diagnosis, monitoring, and treatment are performed by the device on the user. In some other embodiments, the user can be a clinician and the patient can be a third party who is diagnosed or treated by the user. It will also be appreciated that diagnosis and monitoring can be generally referred to as health status analysis. Myopia / Hyperopia / Astigmatism

[0103] Having described various components of an ophthalmic system in the context of medical diagnosis and treatment, an embodiment is described below in which an ophthalmic system is used to treat common eye-related ailments. It should be understood that the following embodiments are illustrative only and should not be taken in a limiting sense. For example, the embodiments described herein are applicable to systems other than ophthalmic systems.

[0104] Vision defects such as myopia (e.g., nearsightedness), hyperopia (e.g., hyperopia), astigmatism, etc. are quite common in the general population. Often, these defects are corrected with corrective lenses. In one or more embodiments, the optics of the ophthalmic system can be modulated to naturally correct the user's vision defects. In one or more embodiments, the ophthalmic system can be configured to automatically or interactively determine the user's optical prescription (e.g., during a set-up procedure or thereafter) and incorporate the optical prescription into the optical ancillary components of the ophthalmic system. The optical prescription can be determined during initialization of the ophthalmic system, during calibration of the system, as part of an ophthalmic prescription configurator program (e.g., for a horopter described herein or for other vision tests), or at any time during use of the ophthalmic system. Biometric data can be used to identify the user and the associated optical prescription. In various embodiments, the wavefront of light projected to the user's eye can be modified based on the determined prescription. In other embodiments, alternatively or in combination, the wavefront of ambient light in front of the user, e.g., light from the ground in front of the user through the ophthalmic system to the user's eye, is modified to provide optical correction. Thus, the user's optical prescription and modifications thereto can be used to modify the user's input light field in real time, and the optical prescription and modifications thereto can be configured to correct one or more optical defects or aberrations. One non-limiting advantage of the embodiments described herein is that the ophthalmic system can be configured to dynamically correct vision defects as the user's vision changes over time, e.g., 2, 3, 4, 6, or more times per year, without the need to replace or replace components in the system. Instead, components can be dynamically reconfigured electronically in real time based on the user's vision changes (e.g., based on the optical prescription) while the ophthalmic device is in use.

[0105] For example, in the case of myopia, light associated with one or more objects is not imaged on the retina, but in front of the retina, as shown in Figure 7A. This causes the objects to appear out of focus. Now, referring to Figure 7B, a concave lens can be used to correct the defect, changing the nature of the incoming light and allowing it to be imaged onto the retina.

[0106] In one or more embodiments, once a user's optical prescription is determined, the user's optical prescription can be modified by generating a desired output spherical wavefront curvature (e.g., a negative output spherical wavefront curvature) by encoding it into the optics of the ophthalmic system. For example, the phrase "encode into the optics" can refer to applying a predetermined voltage to electrodes of an adaptive optics system (e.g., in an embodiment using adaptive optics), where the voltage is applied to the electrodes and the voltage applied to the electrodes is determined based on the desired modified wavefront to correct a refractive error of the eye. Alternatively, in a waveguide stack embodiment, the phrase "encode into the optics" can refer to selectively designating predetermined waveguides to direct light to the correct focal depth corresponding to a particular portion of the eye to generate a modified wavefront to correct a refractive error of the eye. In some embodiments, a negative output spherical wavefront can be encoded into the optics of the ophthalmic system to correct low order aberrations (e.g., defocus) of the user, for example, to correct myopia. In an augmented reality display system, such corrections can be applied to ambient light from the ground, e.g., in front of the user, in a manner similar to eyeglasses. Alternatively, in some embodiments, either in combination or separately, corrections can be applied by correcting the image projected from the ophthalmic system's display (e.g., from the ophthalmic system's processing unit) to the user's eye with an appropriate negative spherical wavefront. In this way, the phase of the projected image can be corrected so that it appears in focus and corrected based on the optical prescription.

[0107] In hyperopia, light associated with one or more objects is not imaged on the retina, but behind the retina, as shown in Figure 8A. This causes the objects to appear out of focus. Now, referring to Figure 8B, a convex lens can be used to correct the defect.

[0108] In one or more embodiments, once the optical prescription is determined, a corrective spherical wavefront (e.g., a positive output spherical wavefront) can be generated by encoding it into the optics of the ophthalmic system. In some embodiments, a positive output spherical wavefront can be generated by encoding it into the optics of the ophthalmic system to correct low order aberrations (e.g., defocus) of the user, for example to correct hyperopia. Such correction can be applied to ambient light from the ground surrounding the user, for example, in front of the user. Alternatively, as described above, the processor can apply the corrected wavefront to correct the image projected from the ophthalmic system based on the determined prescription, so that the projected image appears in focus and is corrected based on the optical prescription. Again, a combination of both encoding and processor correction techniques can be used in the augmented reality system.

[0109] Astigmatism is a condition in which light entering the eye is improperly or partially imaged on the retina. As illustrated generally in FIG. 9A, the shape of the eye may be distorted (usually caused by an irregularly shaped cornea), causing the resulting image to be out of focus and distorted. For example, the curvature along the principal meridian may be different from the curvature along the perpendicular principal meridian. Now, referring to FIG. 9B, an ophthalmic device may correct the astigmatism by applying an appropriate compensatory wavefront curvature correction, for example, along an appropriate transverse axis of the principal meridian.

[0110] More specifically, in various embodiments, once a suitable optical prescription is determined, a suitable compensatory wavefront compensation can be encoded into the ophthalmic optics. A wavefront (e.g., a 4D wavefront) incident on the optics of the ophthalmic system can be modified by the optics (e.g., changing the phase of the incident wavefront) to generate a compensatory wavefront that is incident on the user's eye and corrects the ocular defect. In other words, the optics of the ophthalmic system (e.g., adaptive optics, described below) can be configured to change the focus and / or wavefront of light reaching the user's eye based on, for example, the refractive error of the eye, the shape of the user's eye, such as the shape of the eye's cornea and / or lens, the length of the user's eye (e.g., the eye's natural light transmission length to the retina), etc. In some embodiments, the compensatory wavefront can modulate the phase of a wavefront incident on the optics of the ophthalmic device.

[0111] In some embodiments, higher order aberrations may be difficult to compensate for by spherical wavefront correction, as described above. Thus, in some embodiments, multiple independently controllable lenses may be controlled by an ophthalmic system to form a compound lens capable of correcting higher order aberrations, as described below. In other embodiments, alternatively or in combination, the ophthalmic system may be configured to retrieve a known aberration pattern based on a user's prescription and apply this pattern to an image stored in the ophthalmic system for presentation to the user's eye.

[0112] For example, the Ophthalmic system may store one or more images that may be retrieved by the Ophthalmic system. In some embodiments, the images may be preloaded or generated by the Ophthalmic system. In some embodiments, the images may be part of a dynamic image (e.g., video). In other embodiments, the images may be provided from another source external to the Ophthalmic system (e.g., a remote data repository (72)). In other embodiments, alternatively or in combination, the images may be acquired based on ambient light in front of the Ophthalmic system, as described herein. The images may be projected by the Ophthalmic system to the user and may be modified by software included in the Ophthalmic system. The Ophthalmic system may generate and present one or more 2D images to the user's eye, and the system may be configured to modify the images based on the user's optical prescription before projecting the images. In some embodiments, different image contents projected at different focal depths may provide the user with a 3D perception of the image, as described below for an embodiment of an Ophthalmic system with a waveguide stack. In this manner, each image may be a 2D representation of an image at a different focal depth. Each image can be individually modified by software contained in the ophthalmic system, for example, the pattern or collection of pixels forming each image can be modified to counteract, cancel or reduce the effects of errors caused by the eye.

[0113] For example, defects in the retina of the user's eye may cause errors in terms of intensity, shape, magnification, or color seen by the user. In various embodiments, the wavelength of light or the intensity of light of the image projected by the ophthalmic system may be modulated to treat color blindness of the user's eye. For example, the wavelength of light presented to the user may be altered based on a color blindness prescription to correct for color blindness. In some embodiments, modification of the 2D image (e.g., each 2D image of the 2D images may be a 2D representation of an image with a different focal depth) may be used to correct dead spots or weak spots in the eye. For example, by mapping the eye to identify dead spots / weak spots, the light intensity of the projected image may be increased in response to the identified areas of the eye or retina having dead spots or weak spots. Thus, in some embodiments, the image may be modified by altering the intensity of one or more portions of the presented image. For example, a fiber scanning display or spatial light modulator included in the ophthalmic system may vary the intensity while generating the image.

[0114] Another example of correcting an image is to modify the intensity pattern of the image. For example, if the image viewed by the user is known to exhibit radial distortion (e.g., barrel, pincushion, or mustache distortion), a compensating distortion can be applied to the image to correct such distortion. The distortion to be corrected is either the result of a refractive error caused by the eye or the result of a refractive error caused by the optics of the ophthalmic system, and is therefore known by the optical prescription or the ophthalmic system. In this way, the ophthalmic system can correct the refractive error by modifying the intensity pattern of the projected image. For example, if the user's eye causes pincushion distortion in the image, the ophthalmic system can be configured to modify the intensity pattern of the image projected to the user through the display to introduce a predetermined amount of barrel distortion to cancel or reduce the amount of pincushion distortion in the image on the retina that is the inverse of the pincushion distortion. Similarly, the ophthalmic system can be configured to correct the image if the user's eye causes barrel distortion by adding pincushion distortion to the intensity pattern that constitutes the image on the display. In some embodiments, image rectification can be performed to correct for fisheye distortion by modifying the image presented by the display by applying inverse angle and amount distortions.

[0115] In various applications, a combination of wavefront correction and modification of the image produced by the ophthalmic system (e.g., modifying the intensity pattern that makes up the image) can be used to compensate for astigmatism or other imperfections in a user's eye.

[0116] In some embodiments, the ophthalmic system may be a patient-worn ophthalmic device, as shown in FIGS. 3A-3D and 5, where the patient-worn ophthalmic device may be provided to correct vision defects such as myopia, hyperopia, and astigmatism. The ophthalmic device includes a display device (62) including a light source (18) configured to project light (38) that is directed to a user's eye within a display lens (106) of the display device (62). The ophthalmic device may also direct ambient light from the ground, e.g., from the ground in front of the user, to the user's eye through the display lens (106). The display device (62) also includes one or more adaptive optics (e.g., a variable focus element or VFE, an electrically reconfigurable reflective or refractive optical element, etc.). Such adaptive optics may be included in the display lens (106), or may be located between the display lens (106) and the light source (18), or may be located between the display lens (106) and the eye, or elsewhere in the optical path of the eye. The adaptive optics or VFE is an optical element that can be dynamically altered, for example, by applying an electrical signal to the optical element to change the shape of a wavefront incident on the optical element. The adaptive optics may be a reflective optical element, such as a deformable mirror, or a transmissive optical element, such as a dynamic lens (e.g., a liquid crystal lens, an electroactive lens, a conventional refractive lens with a movable element, a mechanically deformable lens, an electrowetting lens, an elastic lens, or multiple fluids with different refractive indices). By altering the shape or other properties of the adaptive optics, the wavefront incident on the optical system may be altered to provide optical correction, for example, by changing the focus of the wavefront as described herein.

[0117] In various embodiments, the ophthalmic device includes an outward-facing camera configured to capture ambient light from the environment surrounding the user. For example, the ophthalmic device may include one or more wide-field machine vision cameras (16) operably connected to the local processing module (70). These cameras may be configured to capture the environment around the user. In one embodiment, these cameras (16) are dual capture visible / infrared cameras. Images captured by the cameras (16) are stored in a digital memory of the ophthalmic device and retrieved for subsequent processing. The images are then retrieved by the ophthalmic device, which may then re-render the captured images to the user by projecting the images via the display device (62).

[0118] In various embodiments, the ophthalmic device may include a biofeedback system configured to determine a user's comfort level when viewing an object or image. For example, if the user's eyes are moving, changing focus, changing pupil size, changing convergence, etc., these may be indicators that the user is unable to comfortably view the object or image. In some embodiments, the change in focus or focus-related behavior may be expressed as erratic and random fluctuations, instability, and / or wobble in the focus or behavior of the eye. Instability or wobble in the focus or focus-related behavior may be an indication that the user is struggling to focus on the object or image or to focus so that the object or image is visible. Thus, the biofeedback system may receive input regarding the state or characteristics of the user's eye in real time.

[0119] In various embodiments, the ophthalmic device includes one or more eye-tracking cameras or other cameras or imaging systems that track one or more eyes of a user. For example, some embodiments may utilize a camera (24) (e.g., an infrared light camera) paired with a light source (26) (e.g., an infrared light source), where the camera (24) is configured to monitor and track the user's eyes. These cameras and light sources may be operably connected to a local processing module (70). Such a camera and / or imaging system may monitor eye orientation, eye pupil size, eye convergence, and the direction corresponding to the gaze of each eye. As described below in connection with horopter technology, the camera (24) may be configured to determine the focusing of the user's eyes. In some embodiments, the camera (24) may be configured to determine the convergence point of the eyes, as described above with reference to Figures 5 and 6.

[0120] In some embodiments, the ophthalmic device includes a gyroscope sensor, an accelerometer, other sensors, or a combination thereof to monitor changes in head position, head pose, or head orientation. In some embodiments, the display device (62) can include a sensor assembly (39) configured to detect the movement of the display device (62) caused by the user's head movement and the orientation of the display device (62). The biofeedback system can be configured to receive the detected head movement, and if the frequency and / or magnitude of the movement exceeds a threshold, the system can be configured to determine that the user is unable to comfortably view the image. For example, constant head movement can indicate that the person is searching for a comfortable viewing position for the image. If such symptoms appear and indicate that the person may not be focusing well, the ophthalmic system can warn the user that such...
