Technical Field

[0004] The present disclosure relates to various methods and systems for diagnosing, monitoring, and treating health conditions and diseases, including ocular and other conditions and diseases. Background Art

[0005] Clinicians routinely use ophthalmic instruments and techniques to diagnose and treat eye-related conditions. Figure 1 An example of a conventional ophthalmic device is shown. As shown, the patient may be positioned in a specific fixed position for the entire duration of the procedure, which may last between a few seconds and several minutes. Such positioning is considered necessary to properly align the patient's eye with the ophthalmic device so that the measurement and / or treatment procedure can be performed on the patient's eye.

[0006] Unfortunately, ophthalmic devices tend to be large, bulky, and expensive devices, and are typically only used in a doctor's office. As a result, the patient may need to make an appointment with an optometrist and see a doctor for any diagnosis or treatment. This can be a delaying factor for many patients, who may delay a visit to the doctor's office for a long time until the condition worsens. If the patient is diagnosed or treated promptly, relief may be easier, but worsening conditions may require even more drastic treatment or surgery to resolve. In addition, the large, bulky nature of most ophthalmic devices forces the patient to be placed in an uncomfortable position for a long time, which in turn may actually increase the risk of misdiagnosis and patient error.

[1456] Various embodiments of the present invention are directed to methods, systems and articles for implementing a user-wearable health system that can be used to perform health-related diagnosis, monitoring and treatment on the user. Various objects, features and advantages of the present invention are described in the detailed description, drawings and claims.

[1457] Various embodiments will be described in detail with reference to the accompanying drawings, and the accompanying drawings are provided as illustrative examples of the present invention so that those skilled in the art can practice the present invention. It is worth noting that the following drawings and embodiments are not meant to limit the scope of the present invention. In the case where some elements of the present invention can be partially or completely implemented using known components (or methods or processes), only those parts of these known components (or methods or processes) necessary for understanding the present invention will be described, and the detailed description of other parts of such known components (or methods or processes) will be omitted so as not to obscure the present invention. In addition, various embodiments include current and future known equivalents of the components mentioned herein by way of illustration.

[1458] Methods and systems for diagnosing and / or treating a patient's health conditions through a user-wearable health system (e.g., a user-wearable ophthalmic device that interacts with the user's eyes) are disclosed. In one or more embodiments, the device may be a head-mounted system capable of executing one or more diagnostic or treatment regimens. In some other embodiments, the device may be fixed (e.g., fixed in a doctor's office). In one or more embodiments, the device may be an augmented reality system that advantageously combines many augmented reality (AR) and / or virtual reality (VR) technologies for health or eye purposes. In some other embodiments, clinicians may wear the device for the purposes of diagnosis and / or simulation and training. The various embodiments described below discuss new paradigms for health systems associated with AR systems, but it should be understood that the technology disclosed herein can be used independently of any existing and / or known AR systems. Therefore, the examples discussed below are for illustrative purposes only and should not be read as limited to AR systems.

[1459] As described above, embodiments of the present invention present a new paradigm in which a user-wearable diagnostic health or health treatment system (generally referred to herein as a 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-related (e.g., eye-related) diseases. In some embodiments, diagnosis and / or treatment may be provided by optics, mechanical structures, processing algorithms, or any combination of the foregoing. In some other embodiments, the health system worn by the patient may further require sensing and / or stimulation capabilities for enhanced treatment or diagnostic purposes. In some embodiments, a head-mounted augmented reality system may be used to provide various health-related (e.g., ophthalmic) measurements, assessments, diagnoses, or treatments.

[1460] Given that the head mounted augmented reality display system interacts with the user's eyes, many applications for eye-related diagnosis and treatment can be envisioned. In addition, many other applications in non-eye diagnosis and treatment can be similarly envisioned. Therefore, the disclosure provided herein is not limited to diagnosing, monitoring, and treating the eyes. The embodiments disclosed herein can also be applied to diagnosing, monitoring, and treating other areas of a user's health, including but not limited to the user's cardiovascular and neurological health.

[1461] Many embodiments of the health system will be discussed with respect to various eye-related and other diseases.Before examining the various embodiments of the health system, the following will briefly discuss the biology of the human eye to provide context for common diseases that may affect patients.

[1462] refer to Figure 2 , depicting a simplified cross-section of the human eye, characterized by the cornea (42), iris (44), lens or "lentisk" (46), sclera (48), choroid (50), epoxies (52), retina (54), and optic nerve pathways (56) to the brain. The epoxies are the center of the retina, used for viewing medium detail; in the center of the epoxies is a portion of the retina called the "fovea," used for viewing the finest detail and containing more photoreceptors than any other part of the retina (approximately 120 cones per degree of vision). The human visual system is not a passive sensor type system; rather, it is configured to actively scan the environment. Rather than being in a constant state of constant response to stimuli, the eye's photoreceptors change in response to changes in stimuli in a manner roughly similar to using a flatbed scanner to capture an image or using fingers to read Braille from paper.

[1463] Thus, movement is required to present the photoreceptor information to the brain (such as a linear scanner array moving across a sheet of paper in a flatbed scanner, or a finger moving over a word of Braille imprinted on paper). In fact, experiments with substances such as cobra venom (which has been used to paralyze eye muscles) have shown that human subjects will experience blindness if their eyes are open, observing a static scene with venom-induced eye paralysis. In other words, in the absence of a change in stimulus, the photoreceptors provide no input to the brain, and blindness is experienced. This is believed to be at least one reason why normal human eyes are observed to jitter back and forth or side to side in so-called "microsaccades."

[1464] As mentioned above, the fovea of ​​the retina contains the greatest density of photoreceptors, and while humans typically have the perception of having high-resolution visualization capabilities across the entire visual field, they typically actually only have a small high-resolution center that is being mechanically swept a lot, as well as a persistent memory of the high-resolution information that was recently captured by the fovea. In a somewhat similar manner, the eye's focus control mechanism (the ciliary muscle is operatively coupled to the lens via: eyelash relaxation resulting in tightened eyelash-attached fibers, flattening the lens for farther focal distances; eyelash contraction resulting in relaxed eyelash-attached fibers, which allows the lens to assume a more rounded geometry for closer focal distances) jiggles about 1 / 4 to 1 / 2 of the refractive power back and forth to periodically induce a small amount of so-called "refractive blur" at the near and far ends of the target focal distance; this is used as a looping negative feedback by the brain's accommodation control circuitry, which aids in the ongoing correction process and keeps the retinal image of a fixed object roughly in focus.

[1465] The brain's visualization centers also gain valuable perceptual information from the movement of the eyes and their positions relative to each other. The vergence movement of the eyes relative to each other (i.e., the rolling movement of the pupils toward or away from each other to converge the eyes' line of sight and thus fixate on an object) is closely related to the focusing (or "accommodation") of the lenses of the eyes. Under normal circumstances, changing the focus of the lenses of the eyes, or accommodating the eyes, to focus on objects at different distances will automatically cause matching changes in vergence at the same distance, with a relationship known as the "accommodation-vergence reflex." Likewise, under normal circumstances, changes in vergence will trigger matching changes in accommodation. As with most traditional stereoscopic AR or VR configurations, it is known that working with this reflex produces eyestrain, headaches, or other forms of discomfort to the user.

[1466] Movement of the head, which houses the eyes, also has a critical impact on the visualization of objects. Humans move their heads to visualize the world around them; people often stay in a relatively constant state, repositioning and reorienting their heads relative to objects of interest. In addition, most people like to move their heads when their eye gaze needs to move more than about 20° from center to focus on a particular object (i.e., people generally don't like to see things out of the corner of their eyes). Humans also typically scan or move their heads relative to sound to improve audio signal capture and take advantage of the geometry of the ears relative to the head. The human visual system obtains strong depth cues from so-called "head movement parallax", which is related to the relative movement of objects at different distances as the head moves and the eye vergence distance, i.e., if a person moves their head left and right and keeps it fixed on an object, items far away from the object will move in the same direction as the head; items in front of the object will move opposite to the head; these are very obvious cues where objects are spatially located relative to the person's environment, perhaps as powerful as stereo vision). Of course, head movement is also used to look around objects.

[1467] In addition, the head and eye movements are coordinated with the so-called "vestibulo-ocular reflex", which stabilizes the image information relative to the retina during head rotation, thereby keeping the object image information roughly centered on the retina. In response to the head rotation, the eyes reflexively and proportionally rotate in the opposite direction to maintain a stable fixation on the object. Due to this compensatory relationship, many people can read a book while shaking their heads back and forth (interestingly, if the book is rocked back and forth at the same speed, and the head is roughly stationary, this is usually not the case, and people are unlikely to read a moving book; the vestibulo-ocular reflex is a head and eye movement coordination that is generally not used for manual movement). Since the user's head movement may be relatively directly related to the eye movement, this paradigm may be important for the patient health system, and the system will preferably be prepared to cooperate with this relationship. Therefore, when designing a patient-worn or fixed display-based health system, it is preferred to consider the characteristics of the human eye, and sometimes the limitations of the human eye, to provide meaningful virtual reality content that cooperates with the natural mechanism of the eye, rather than emphasizing it. In addition, in the case of health-related applications of augmented reality display systems, this can provide various advantages as disclosed herein. As described above, the display of the health system can be implemented independently of the augmented reality (AR) system, but for illustration purposes, many of the following embodiments are described with respect to the AR system.

[1468] Reference now FIG. 3A to FIG. 3D , showing some common component options. It should be understood that although FIG. 3A to FIG. 3D A head mounted display is shown, but in some embodiments the same components may also be incorporated into a stationary health system.

[1469] like Figure 3A As shown, a user (60) is depicted wearing a patient-worn ophthalmic device that includes a frame (64) structure coupled to a display system (62) located in front of the user's eyes. Depending on the application of the health system, the frame 64 may be coupled to multiple ophthalmic-specific measurement subsystems. Some embodiments may be constructed for one or more ophthalmic applications, and other embodiments may be general-purpose AR systems that are also capable of ophthalmic applications. In either case, the following paragraphs describe possible components of the health system or AR system used for ophthalmic instrumentation and / or treatment.

[1470] In one or more embodiments, the health system is worn by a patient or user. In some other embodiments, the health system can be worn by another person, such as a physician or clinician, and can be used to perform a set of diagnostic tests and / or treatment plans on a patient who is not the wearer of the system. It should be understood that any of the following applications can be used with a health system worn by another person and used to perform diagnostic tests and / or treatment plans on a patient.

[1471] A speaker (66) can be coupled to the frame (64) in the depicted configuration and positioned adjacent to the user's ear canal (in one embodiment, another speaker (not shown) is positioned adjacent to the user's other ear canal to provide for stereo / shapeable sound control). A microphone (55) can also be coupled to the frame to detect sounds from the user or the surrounding environment. In some embodiments, another microphone (not shown) can be provided, for example, coupled to the frame (64) on the user's right hand side. In one or more embodiments, the health system can have a display (62) that is operably coupled (68) to a local processing and data module (70), for example, via a wired lead or a wireless connection, which can be mounted in a variety of configurations, for example, fixedly attached to the frame (64), fixedly attached to a helmet or hat (80), such as a headset. Figure 3B As shown in the embodiment of the present invention, the headset is embedded in the headset and can be removably attached to the torso (82) of the user (60) in a backpack-type configuration, such as Figure 3C or removably attached to the hip (84) of the user (60) in a belt-coupled configuration, as shown in the embodiment of Figure 3D As shown in the embodiment.

[1472] The local processing and data module (70) may include a diopter-efficient processor or controller and digital memory such as flash memory, both of which may be used to assist in processing, caching and storing data that is a) captured from sensors (e.g., image capture devices (e.g., cameras), microphones, inertial measurement units, accelerometers, compasses, GPS units, radios and / or gyroscopes) that may be operably coupled to the frame (64); and / or b) acquired and / or processed using a remote processing module (72) and / or a remote data repository (74), possibly transmitted to the display (62) after such processing or retrieval. The local processing and data module (70) may be operably coupled (76, 78) to the remote processing module (72) and the remote data repository (74), such that these remote modules (72, 74) are operably coupled to each other and may serve as resources for the local processing and data module (70), for example, via a wired or wireless communication link.

[1473] In some embodiments, the remote processing module (72) may include one or more relatively powerful processors or controllers configured to analyze and process data and / or image information. In some embodiments, the remote data repository (74) may include a relatively large-scale digital data storage facility, which may be available via the Internet or other network configuration in a "cloud" resource configuration. In some embodiments, all data is stored and all calculations are performed in the local processing and data module, allowing full autonomous use from any remote module.

[1474] Advantageously, similar to FIG. 3A to FIG. 3D Those described, the health system (or AR system with ophthalmic applications) provides unique access to the user's eyes and head. Given that the health system interacts with the user's eyes to allow the user to perceive 3D virtual content, and in many embodiments, tracks various biometrics related to the user's eyes (e.g., eye convergence, eye movement, retinal structure, geometry of the previous eye and the next eye, patterns of eye movement, etc.), the resulting tracking data can be advantageously used in health-related applications, as further described in detail herein. This unprecedented access to the user's eyes implements a variety of health applications. Depending on the type of health disease, the health system can be configured to provide imaging, sensing (including measurement) and / or stimulation of the user's eyes to diagnose and / or treat the disease.

[1475] In one or more embodiments, the augmented reality display system can be used as a patient-worn or user-worn ophthalmic device. Clinicians use ophthalmic instruments to observe the patient's eyes, perform medical procedures and / or examine the user's eyes. Traditionally, ophthalmic devices are large, bulky, fixed devices and often require patients to go to a doctor's office, where a clinician or doctor performs eye-related examinations on the patient. Typically, the patient is confined to the ophthalmic instrument device (e.g., chin on the chin rest of the ophthalmic device, head forward, etc.) until the clinician completes the series of examinations. Therefore, current methods have a number of limitations.

[1476] In addition to using large, bulky devices to perform the examinations, traditional methods require physician supervision, and the patient may need to return to the clinician's office repeatedly for further examinations / progress assessments and may be required to remain in an uncomfortable or restricted position for extended periods of time. Furthermore, given the short duration of patient exposure to the ophthalmic device, the amount of data that the clinician can collect in order to diagnose or treat the patient is limited. Additionally, traditional methods do not account for dynamic changes in the user's behavior and the user's orientation. Many examinations performed under traditional methods require the user to be restricted to a specific, typically stationary position. However, if the user is performing a visual field examination and has a limited attention span, they may move their head and eyes, which may create noise and may result in inaccurate examination results.

[1477] In one or more embodiments, similar to FIG. 3A to FIG. 3D The head-mounted health (e.g., ophthalmic) device shown can be used by a patient to track data, identify and correct one or more eye-related diseases, and / or help prevent other health problems. In one or more embodiments, the AR display system can be used as a head-mounted health (e.g., ophthalmic) device. It should be understood that multiple embodiments described below can be implemented as head-mounted embodiments, while other embodiments can be implemented as fixed devices. In addition, some embodiments may utilize AR technology to implement systems and methods for diagnosis, monitoring and / or treatment through physician supervision (e.g., for medical safety issues, regulatory issues, etc.), while other embodiments may be implemented as self-diagnosis and / or monitoring through a head-mounted health device or AR device, or implemented as part of a treatment plan for a specific disease, as described herein. For purposes of illustration, the present disclosure will focus primarily on head health devices, such as health systems, and particularly AR devices, but it should be understood that the same principles may also apply to non-head-mounted embodiments.

[1478] In one or more embodiments, the AR display device can be used as a patient-worn health device, such as a patient-worn health system. The device can be generally suitable for a specific user's head, and the optical elements are aligned with the user's eyes. These configuration steps can be used to help ensure that the best augmented reality experience is provided to the user without causing any physiological side effects, such as headaches, nausea, discomfort, etc. Therefore, in one or more embodiments, the patient-worn health system is configured for each individual user (physically and digitally), and a set of programs can be calibrated specifically for the user. In other cases, loosely fitted AR devices can be used comfortably by a variety of users. For example, in some embodiments, the patient-worn health system knows the distance between the user's eyes, the distance between the head-mounted display and the user's eyes, the curvature of the user's forehead, the distance to the ear, or one or more of the height of the bridge of the nose for correct fitting. All of these measurements can be used to provide a suitable head-mounted display system for a given user. In some other embodiments, such measurements may not be necessary to perform ophthalmic functions.

[1479] For example, refer to FIG. 4A to FIG. 4D , the health system can be customized for each user. Figure 4A As shown, in one or more embodiments, the user's head shape 402 can be considered when installing a head-mounted patient-worn health system. Figure 4B As shown, the eyepiece 404 (e.g., optical elements, structures for optical elements, etc.) can be rotated or adjusted horizontally and vertically for the comfort of the user, or rotated for the comfort of the user. Figure 4C As shown, the rotation point of the headset relative to the user's head can be adjusted based on the structure of the user's head. Figure 4D As shown, the interpupillary distance (IPD) (ie, the distance between the user's eyes) may be compensated.

[1480] In the context of a patient-worn health system, this aspect of the head-mounted device can be advantageous because the system already has a set of measurements about the user's physical characteristics (e.g., eye size, head size, distance between eyes, etc.) as well as other data that can be used for treatment and diagnosis of the patient.

[1481] In addition to the various measurements and calibrations performed on the user, the patient-worn health system can be configured to track a set of biometric data about the user for patient identification and secure communication. For example, the system can perform iris recognition and / or retinal matching for patient identification, and the system can track eye movements, eye movement patterns, blink patterns, eye convergence, fatigue parameters, eye color changes, focal length changes, and many other parameters, which can be used to provide an optical augmented reality experience to the user. In the case of an AR device for healthcare applications, it should be understood that some of the above aspects can be part of a general AR device and other features can be combined for specific health-related applications.

[1482] Reference now Figure 5 , various components of an example patient-worn health display device will be described. It should be understood that other embodiments may have more or fewer components depending on the application (e.g., a specific diagnostic tool) in which the system is used. However, Figure 5 A basic idea of ​​some of the various components and types of biometric data that can be collected and stored by a patient-worn health system or AR device is provided. Figure 5 A simplified version of a head-mounted health system 62 is shown in the block diagram to the right for illustration purposes.

[1483] refer to Figure 5 , shows one embodiment of a suitable user display device (62) including a display lens (106) mountable to a user's head or eye by a housing or frame (108) that is similar to frame (64) ( FIG. 3A to FIG. 3D ). The display lens (106) may include one or more transparent reflectors positioned by the housing (108) in front of the user's eye (20) and configured to reflect the projection light (38) into the eye (20) and facilitate beam shaping while also allowing transmission of at least some light from the local environment. As shown, two wide field of view machine vision cameras (16) are coupled to the housing (108) to image the environment surrounding the user; in one embodiment, these cameras (16) are dual-shooting visible light / invisible (e.g., infrared) light cameras.

[1484] Continue to refer Figure 5As shown, a pair of scanning laser shaped wavefront (i.e., for depth) light projector modules with display reflectors and optical elements are configured to project light (38) into the eye (20). The depicted embodiment also includes two miniature infrared cameras (24) paired with infrared light sources (26, such as light emitting diodes "LEDs"), which are configured to track the user's eyes (20) to support rendering and user input. The system (62) is also characterized by a sensor assembly (39), which may include X, Y and Z axis accelerometer capabilities and magnetic compass and X, Y and Z axis gyroscope capabilities, preferably providing data at a relatively high frequency (e.g., 200 Hz). The depicted system also includes a head posture processor (36), such as an ASIC (application specific integrated circuit), FPGA (field programmable gate array) and / or ARM processor (advanced reduced instruction set machine), which can be configured to calculate real-time or near real-time user head posture based on wide field of view image information output from the camera (16).

[1485] A processor (32) is also shown, which is configured to perform digital and / or analog processing to derive posture from gyroscope, compass and / or accelerometer data from the sensor assembly (39). The depicted embodiment is further characterized by having a GPS (37, global positioning satellite) subsystem to assist in posture and positioning analysis. In addition, the GPS can further provide remote-based (e.g., cloud-based) information about the user's environment. This information can be used for diagnostic purposes. For example, if the user is located in an area with high pollen in the surrounding air, the information can be used to diagnose and / or treat a specific disease. Alternatively, in another example, information about air pollution in a specific air can be advantageously used when considering treatment options for a specific user. Other types of information (e.g., pollen count, pollution, demographics, environmental toxins, indoor climate and air quality conditions, lifestyle statistics, proximity to medical providers, etc.) can be similarly used in one or more applications.

[1486] The depicted embodiment may also include a rendering engine (34), which may have hardware running a software program configured to provide local rendering information to the user to facilitate manipulation of the scanner wavefront and imaging within the user's eye for the user to view the world. The rendering engine (34) is operatively coupled (105, 94, 100 / 102, 104; i.e., via a wired or wireless connection) to the sensor gesture processor (32), the image gesture processor (36), the eye tracking camera (24), and the projection subsystem (18) so that the rendered light is projected using a scanned laser setup (18) in a manner similar to a retinal scanning display. The wavefront of the projected beam (38) may be bent or focused to coincide with a desired focal length of the projected light.

[1487] A camera (24) (e.g., a small infrared camera) can be used to track the eyes to support rendering and user input (i.e., where the user is looking, the depth being focused; as described below, the eye edges can be used to estimate depth of focus). GPS (37), gyroscopes, compasses, and accelerometers (39) can be used to provide coarse and / or fast pose estimates. Camera (16) images and poses can be combined with data from associated cloud computing resources to map the local world and share the user's view with others and / or a virtual or augmented reality community and / or medical providers. In one or more embodiments, the camera (16) can be used to analyze food, medications, nutrients, and toxins ingested by the user as part of an integrated health and / or wellness system or health monitoring system.

[1488] Continue to refer Figure 5 , the display device (62) may include a drug dispensing module (21) for delivering a drug to a user. The drug dispensing module (21) may include one or more outlets (22) and at least one drug container (23), which may be a reservoir for storing the drug dispensed through the outlet (22). The outlet (22) may be connected to the container (23) by one or more channels (22a), which transfer the drug (e.g., liquid or gas) from the container (23) to the outlet (22). In some embodiments, the outlet (22) may be simply an opening in the frame (108), or may be a nozzle attached to or integral with the frame (108). In some embodiments, the nozzle may be an atomizer. In some embodiments, the channel (22a) is formed by an opening and / or a conduit in the frame (108).

[1489] In one or more embodiments, the display device may include a light module (27) for selectively delivering light to the wearer, for example, for treating the wearer's eyes based on a treatment regimen. The light module (27) may include a light source, which may include a light emitter that emits polychromatic polarized light, a laser, a light emitting diode, a fluorescent lamp, a dichroic lamp, a full-spectrum light source, etc. In some embodiments, one light module (27) may be provided for both eyes. In some other embodiments, the display device may include multiple light modules (27), and each eye may have at least one light module configured to direct light to that eye.

[1490] Although Figure 5 Most of the hardware in the display system (62) shown in FIG. 1 is depicted as being directly coupled to the housing (108) adjacent to the display (106) and the user's eye (20), but the depicted hardware components may be mounted to or housed within other components, such as a belt-mounted component, such as, for example. Figure 3DAs shown. In addition, as described herein, for ease of illustration and description, multiple sensors and other functional modules are shown together. However, it should be understood that some embodiments may include only one or a subset of these sensors and / or modules.

[1491] In one embodiment, in addition to the image gesture processor (36), the sensor gesture processor (32), and the rendering engine (34), Figure 5 All components of the system (62) shown in FIG. 1 are directly coupled to the display housing (108), and communication between the image gesture processor (36), the sensor gesture processor (32), and the rendering engine (34) and the rest of the system can be performed by wireless communication (e.g., ultra-wideband), or by wired communication. The housing (108) depicted is preferably head-mountable and wearable by a user. It may also have a speaker (e.g., speaker (66), FIG. 3A to FIG. 3D ), for example, a speaker that can be inserted into a user's ear and used to provide sound to the user.

[1492] With respect to projecting light (38) into the user's eye (20), in some embodiments, the camera (24) can be used to measure the location at which the center of the user's eye (20) is geometrically directed, which generally coincides with the focal location or "depth of focus" of the eye (20). The three-dimensional surface of all points that the eye is directed toward is called the "binocular view". The focal length can take a finite number of depths, or can be infinitely variable. Light projected from a convergence distance appears to be focused on the subject's eye (20), while light before or after the convergence distance is blurred.

[1493] Furthermore, without being limited by theory, it has been found that spatially coherent light having a beam diameter of less than about 0.7 mm is correctly resolved by the human eye regardless of where the eye is focused; given this understanding, to create the illusion of proper depth of focus, eye vergence can be tracked with a camera (24), and a rendering engine (34) and projection subsystem (18) can be used to render all objects on or near the focused horopter and all other objects at varying degrees of defocus (i.e., using intentionally created blur). Preferably, the system (62) is presented to the user at a frame rate of about 60 frames per second or greater. As described above, preferably, the camera (24) can be used for eye tracking, and the software can be configured to capture not only convergence geometry, but also focus position cues for use as user input. Preferably, such a display system is configured with brightness and contrast suitable for daytime or nighttime use.

[1494] In some embodiments, the display system preferably has a latency of less than about 20 milliseconds for visual object alignment, an angular alignment of less than about 0.1°, and a resolution of about 1 arc per minute, which, without being limited by theory, is believed to be approximately the limitation of the human eye. The display system (62) can be integrated with a positioning system that can involve GPS elements, optical tracking, compasses, accelerometers, and / or other data sources to assist in position and posture determination; local information can be utilized to facilitate accurate rendering when the user views the relevant world (e.g., such information will help the glasses know their position relative to the real world). Since common components of some embodiments of user-worn health systems (e.g., ophthalmic systems) have been described, additional components and / or features related to healthcare and diagnosis will be discussed below. It should be understood that some of the features described below will be common to various embodiments of user-worn health systems or many embodiments of AR systems for health purposes, while others will require more or fewer components for health diagnostic and treatment purposes.

[1495] In some embodiments, the health system worn by the user is configured to display one or more virtual images based on the adaptive adjustment of the user's eyes. Unlike previous 3D display methods that force the user to focus on the location of the projected image, in some embodiments, the health system worn by the user is configured to automatically change the focus of the projected virtual content to allow more comfortable viewing of one or more images presented to the user. For example, if the user's eyes have a current focus of 1m, the image can be projected to coincide with the user's focus. Alternatively, if the user moves the focus to 3 meters, the image is projected to coincide with the new focus. Therefore, some embodiments of the user-worn health system or AR display system allow the user's eyes to operate in a more natural manner without forcing the user to be at a predetermined focus.

[1496] Such a user-worn health system can eliminate or reduce the occurrence of eyestrain, headaches, and other physiological symptoms typically observed with virtual reality devices. To achieve this, various embodiments of the patient-worn health system are configured to project virtual images at varying focal lengths through one or more variable focus elements (VFEs). In one or more embodiments, 3D perception can be achieved through a multi-plane focusing system that projects images on a fixed focal plane away from the user. Other embodiments employ a variable plane focus, where the focal plane moves back and forth in the z-direction to coincide with the user's current focus state.

[1497] In multi-plane focus systems and variable plane focus systems, the health system worn by the patient can use eye tracking to determine the vergence of the user's eyes, determine the user's current focus, and project the virtual image at the determined focus. In other embodiments, the health system worn by the user includes a light modulator that variably projects light beams of different focal points in a raster pattern on the retina through a fiber optic scanner or other light generating source. Therefore, the ability of the health system display to project images at different focal lengths is not only easy to adjust the patient's viewing of 3D objects, but can also be used to compensate for the patient's eye abnormalities, as will be described in further detail below. In some other embodiments, the spatial light modulator can project images to the user through various optical elements. For example, as further described below, the spatial light modulator can project images onto one or more waveguides and then transmit these images to the user.

[1498] Reference now Figure 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 vergence of the user's eyes through an eye tracking system. At 604, the system can estimate the current focus of the user's eyes based on the determined vergence. It should be understood that other embodiments of the AR system (or health system) may not require the use of eye tracking and can display images in rapid sequence to give a 3D perception. Therefore, Figure 6 The process flow should not be considered limiting and is for illustration purposes only.

[1499] If the health system utilizes a multi-depth plane display system (i.e., light is projected on multiple fixed depth planes), the system can determine a focal plane that is closest to the estimated focus based on eye vergence and accommodation at 608. It should be appreciated that accommodation can be measured, for example, 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 at the determined focal plane.

[1500] If the health system utilizes a variable depth flat display system (i.e., one or more focal planes onto which virtual content is projected can be moved back and forth in the z-direction), then at 612, the focus of the system is varied by the VFE to coincide with the estimated focus. At 614, the health system can project at least a portion of the image on the focal plane. Likewise, other embodiments of the health system can use other 3D image generation techniques to provide the user with comfortable, accommodative, reflection-friendly projection of virtual objects.

[1501] Although in some embodiments, images are displayed based on projecting light associated with the virtual image into the user's eyes, any wavelength of light may similarly be projected into the user's eyes. In addition to visible light, infrared light or other forms of light may also be similarly projected through the patient-worn health system. This aspect of the patient-worn health system may also be similarly used to compensate for health anomalies, as described below.

[1502] It should also be understood that although various embodiments are described in which one or more of the various embodiments project light into the user's eye, the health system can also receive light emitted from the user's eye. In one or more embodiments, the light source for 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, etc.). Likewise, other light sources (e.g., OLED, DLP, LCD, etc.) can be similarly used in other embodiments of the health system. In addition to projecting light, in one or more embodiments, the FSD can receive the emitted light. The same optical fiber that projects the light can be used to receive the light. In this mode, the health system can be used as a multi-depth scanner that multiplexes the output modulated light waves with the sensed or captured light waves. In some embodiments, the fiber optic scanner can be used in conjunction with a camera (24) ( Figure 5 ) can be used in conjunction with or in place of the camera, for example, to track or photograph the user's eyes. In one or more embodiments, rather than the FSD being configured to receive light, the health system can have a separate light receiving device to receive light emitted from the user's eyes and collect data associated with the emitted light. Thus, in one or more embodiments, the emitted light and corresponding data can be analyzed to diagnose or treat an abnormality, as will be discussed below.

[1503] Now refer to FIG. 28A to FIG. 28C , discusses various details of the fiber-optic scanning display device. Fig.28A , shows a gradient index or "GRIN" lens 354 fused to the end of a single mode optical fiber. An actuator 350 (eg, a piezoelectric actuator) is coupled to an optical fiber 352 and can be used to scan the optical fiber tip.

[1504] refer to Fig.28B , the multi-core optical fiber 362 can be scanned (e.g., by a piezoelectric actuator 368) to produce a set of beamlets with multiple angles of incidence and intersection points, which can be relayed by a waveguide (370) to the eye 58. Thus, in one embodiment, a collimated light field image can be injected into the waveguide and the light field display can be directly translated to the human eye without any additional refocusing elements.

[1505] Display systems have been created in the past that use eye or gaze tracking as input, and save computing resources by creating only a high-resolution rendering for where a person is looking at that time, but a lower resolution is presented to the rest of the retina; in this configuration, the position of the high-resolution portion relative to the low-resolution portion can be dynamically dependent on the tracked gaze position, which may be referred to as a "foveated rendering display."

[1506] Improvements to this configuration may include a scanning fiber display with a pattern spacing that can be dynamically slaved to the tracked eye gaze. For example, by operating a typical scanning fiber display in a spiral pattern, such as Fig.28C As shown ( Fig.28C The leftmost portion 510 of the image in FIG. 5 shows a helical movement pattern of a scanning multi-core optical fiber 514 ; Fig.28C The rightmost portion 512 of the image in FIG. 5 shows the helical movement pattern of a scanned single optical fiber 516, for comparison), the constant pattern pitch providing uniform display resolution.

[1507] It should be understood that in addition to displaying images or acting as an imager, the display system can provide illumination for imaging the eye or its surrounding tissue. In one or more embodiments, the health system may include an optical scanning or optical sensing module to allow the device to scan the anterior and inner portions of the eye using known visible and invisible light spectroscopy techniques, including visible light imaging, photorefraction, optical coherence tomography (OCT), and light field microscopy (LFM). In one or more embodiments, the ophthalmic system may also include a light field imaging module to simultaneously capture multiple images of the eye at different focal lengths. It should be understood that the display (e.g., FSD) can be advantageously configured so that multiple frequencies of light can be emitted simultaneously by the display. For example, the FSD may include a single-core optical fiber or may include a multi-core optical fiber, which can advantageously emit multiple frequencies of light simultaneously.

[1508] In the context of healthcare and diagnostics, the type, frequency, color scheme, location, etc. of one or more images presented to a user may be advantageously manipulated for the purpose of diagnosing and treating one or more conditions. For example, certain diseases may require strengthening one eye relative to the other. To this end, a treatment regimen may be designed to "train" the weak eye by providing increased stimulation to the weak eye compared to the strong eye. Or, in another example, due to macular degeneration, a particular portion of the retina may have reduced sensitivity; to combat this, the image may be modulated or reformatted and projected to the periphery of the retina, thereby compensating for the user's reduced field of view. Thus, as will be described in further detail below, the ability of a health system to modulate multiple parameters related to the projection of virtual images may be used to diagnose and / or treat certain health abnormalities.

[1509] In addition, using the various principles outlined above, health systems can be designed to provide diagnosis using a stimulus-response-measurement analysis process. For example, these devices can be used by clinicians, or in other embodiments, certain diseases can simply be "diagnosed" or have symptoms recognized by patients (e.g., eye fatigue, dry eyes, high blood pressure, stroke or epileptic seizures, etc.). This may greatly help users actively control their health and prevent the occurrence of diseases by actively paying attention when certain symptoms begin. Such diagnosis can be performed by analyzing contemporaneous data using historical data related to one or more tracked biometric parameters and environmental changes. In one or more embodiments, the health system can also be configured to provide information prompts, send alerts to users and / or doctors or others, or assist with other response means.

[1510] It should be understood 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 from a clinician or other person) or semi-autonomous (i.e., some degree of input or control from 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 network or fully remote (e.g., cloud-based) implementation (e.g., a software-controlled implementation) of a health system for diagnosing, monitoring, or treating a user, or in an implementation in which a clinician wears the health system to examine a patient.

[1511] As about Figure 5 As discussed, in one or more embodiments, the health system can be designed with many additional health-related sensors. The health system can include many sensors (e.g., accelerometers, gyroscopes, temperature sensors, pressure sensors, light sensors, non-invasive blood glucose sensors, ETCO2, EEG and / or other physiological sensors, etc.) to monitor one or more physiological responses of the user.

[1512] As described herein, in one or more embodiments, the health system includes an eye tracking module. The eye tracking module can be configured to determine the vergence of the user's eyes in order to determine appropriate normal eye accommodation for projecting one or more virtual images (through a direct relationship between vergence and eye accommodation), and can also be configured to track one or more eye-related parameters (e.g., eye position, eye movement, eye chart, etc.). This data can be used for several health-related diagnostic and therapeutic applications, as described below.

[1513] It is obvious from the description herein that the health system can be used for diagnosis, monitoring and treatment, which may include eye-related diagnosis, monitoring and treatment. In such eye-related applications, the health system may be referred to as an ophthalmic system. It is also obvious from the description herein that the user (or wearer) of the device may be referred to as a patient, wherein the user is diagnosed, monitored and treated by the device. In some other embodiments, the user may be a clinician, and the patient is a third party, which may be evaluated and treated by the user. It will also be understood that diagnosis and monitoring may generally be referred to as health analysis.

[1514] Myopia / hyperopia / astigmatism

[1515] Having described various components of the ophthalmic system in the context of healthcare diagnosis and treatment, embodiments of using the ophthalmic system to compensate for common eye-related diseases will be described below. It should be understood that the following embodiments are for illustrative purposes only and should not be viewed under limited light. For example, the embodiments described herein may also be applied to other non-ophthalmic systems.

[1516] Vision defects such as myopia (e.g., nearsightedness) and hyperopia (e.g., farsightedness), astigmatism, etc. are very common in the general population. Typically, these defects are corrected by corrective lenses. In one or more embodiments, the optical elements of the ophthalmic system can be modulated to naturally compensate for the user's vision defects. In one or more embodiments, the ophthalmic system can be configured to automatically or interactively determine (e.g., during or after the installation process) the user's optical prescription and incorporate the optical prescription into the optical subcomponents of the ophthalmic system. The optical prescription can be determined as part of an eye prescription configurator program (e.g., a comprehensive refraction tester or other vision test described herein) during the initialization of the ophthalmic system, the calibration of the system, or at any time when the ophthalmic system is used. Biometric data can be used to identify the user and the associated optical prescription. In various embodiments, the wavefront of the light projected into the user's eyes can be modified based on the determined prescription. In other embodiments, alternatively or in combination, the wavefront of the ambient light in front of the user (e.g., light transmitted to the user's eyes from the surrounding environment in front of the user through the ophthalmic system) is modified to provide optical correction. Thus, the user's optical prescription and changes thereto can be used to make real-time changes to the user's incident light field and 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 requiring replacement or substitution of parts incorporated into the system. Rather, components can be electrically reconfigured dynamically in real-time during use of the ophthalmic device based on changes made to the user's vision (e.g., optical prescription).

[1517] For example, in the case of myopia, light associated with one or more objects is focused in front of the retina, e.g. Fig. 7A This causes objects to appear out of focus. Figure 7B , a concave lens can be used to compensate for the discomfort, change the properties of the incoming light, and focus the light on the retina.

[1518] In one or more embodiments, once the user's optical prescription has been determined, a desired power spherical wavefront curvature (e.g., a negative power spherical wavefront curvature) may be encoded into an optical element of an ophthalmic system to correct the user's optical prescription. For example, the phrase "encoded into an optical element" may refer to applying a voltage to an electrode of an adaptive optical element (e.g., in an embodiment employing an adaptive optical element), wherein the voltage applied to the electrode and the voltage to be applied to the electrode are determined based on a desired compensating wavefront to correct a refractive error in the eye. Alternatively, in an embodiment of a waveguide stack, the phrase "encoded into an optical element" may refer to selectively addressing a waveguide to direct light to an appropriate depth of focus for a portion of the eye to produce a compensating wavefront to correct a refractive error in the eye. In some embodiments, a negative power spherical wavefront is encoded into an optical element of an 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 correction may be applied to ambient light from the surrounding environment, e.g., light in front of the user, similar to a pair of glasses. Alternatively, in some embodiments, in combination or alternatively, correction may be applied by modifying the image projected to the user's eye by a display in the ophthalmic system using an appropriate negative spherical wavefront (e.g., by a processor of the ophthalmic system.) The phase of the projected image may thus be modified so that the projected image appears focused and corrected based on the optical prescription.

[1519] In the case of hyperopia, light associated with one or more objects is focused behind the retina, e.g. Fig. 8A This causes objects to appear out of focus. Figure 8B , a convex lens can be used to compensate for the anomaly.

[1520] In one or more embodiments, once the optical prescription has been determined, a compensating spherical wavefront (e.g., a positive power spherical wavefront) may be encoded into the optical elements of the ophthalmic system. In some embodiments, a positive power spherical wavefront is encoded into the optical elements of the ophthalmic system to correct low-order aberrations (e.g., defocus) of the user, for example, to correct hyperopia. This correction may be applied to modify ambient light from the world around the user, for example, in front of the user. Alternatively, as described above, the processor may apply the corrected wavefront to modify the image projected by the ophthalmic system based on the determined prescription so that the projected image appears to be focused and corrected based on the optical prescription. Again, a combination of the two may be used in an augmented reality system.

[1521] Astigmatism is a condition in which light entering the eye is incorrectly or partially focused onto the retina. Fig.9A As schematically shown in , the shape of the eye may be distorted (usually caused by an irregularly shaped cornea), which causes the resulting image to be out of focus and distorted. For example, the curvature along a meridian may be different from the curvature along a perpendicular meridian. Now referring to Fig. 9B , an ophthalmic device can correct astigmatism by applying an appropriate level of wavefront curvature correction compensation, for example, along an appropriate transverse axis of the meridian.

[1522] More specifically, in various embodiments, once an appropriate optical prescription has been determined, appropriate compensatory wavefront corrections may be encoded into the optical elements of the ophthalmic system. A wavefront (e.g., a 4D wavefront) incident on an optical element of the ophthalmic system may be modified by the optical element (e.g., modifying the phase of the incident wavefront) to produce a compensatory wavefront incident on the user's eye, thereby correcting defects in the eye. In other words, the optical elements of the ophthalmic system (e.g., an adaptive optical element as described below) may 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 (e.g., the shape of the cornea and / or lens in the eye), the length of the user's eye (e.g., the length of the eye's natural optical transmission to the retina), etc. In some embodiments, the compensatory wavefront may modify the phase of the wavefront incident on the optical element of the ophthalmic device.

[1523] In some embodiments, higher order aberrations may be difficult to compensate for by spherical wavefront correction as described above. Therefore, in some embodiments, multiple independently controllable lenses may be controlled by the ophthalmic system to form a composite lens that can correct for higher order aberrations, as described below. In other embodiments, alternati...
