The system may be designed to provide a high level of flexibility in the configuration of the health assessment subsystems. A customer for the health assessment system may be able to arrange for any combination of assessment subsystems.

In embodiments and in FIG. 3A the systems and methods disclosed herein may comprise a health service facility 300 that may interact with a seated user. The health service facility 300 may comprise a base 301 that supports a carousel sensor suite system 302 configured to deliver selected sensors to the user's eyes at a user interface aperture, which may also be called the examination window 304. The base 301 may comprise the support electronics and dedicated processors, an example of which may be seen in FIGS. 1A and 1B. The carousel 303 may comprise a plurality of suitable sensors 305 in side view, and at 306 in a top view of a rotating wheel system.

In embodiments and in FIG. 2A, the health assessment system sensor modules may comprise a glaucoma sensor 271.

In embodiments and in FIG. 3A, the user may interact with the system via a keyboard 307 and view a display 308 located below the examination window 304. Embodiments Details of the sensor mounting and transport system are shown in FIGS. 4A, 4B, and 5. In embodiments and in FIG. 3B, the sensor suite may be mounted directly to the user interface 327 of the housing 326. In this embodiment, as shown at 325 in FIG. 3B for a sitting user and at 335 in FIG. 3C for a standing user, the suite of sensor(s) 340 may be mounted in juxtaposition to a display screen 350 which may also have a touchscreen for user input, as shown in FIGS. 3B, 3C, and 3D. In embodiments, a computer keyboard 360 may be used for accepting user inputs to the system.

In embodiments, the sensor suite shown at 340 in FIGS. 3B, 3C, and 3D may contain sensors configured for a single specific purpose, such as, but not limited to, auto-refraction or glucose monitoring, or may contain a sensor with multiple capability, depending on the analysis software associated with the problem being addressed. The sensor module may comprise a lens system for focusing on various parts of the eye, an image capture system comprising a Charge Coupled Device (“CCD”) commonly found in digital cameras, and various filters to isolate different wavelengths of light that are germane to the particular analysis of the sensor module. The lens system may be focused on any part of the eye, including the cornea, the aqueous humor liquid between the cornea and the iris, the lens of the eye, the vitreous humor in the interior of the eyeball, and the retina or the macular region of the retina. In embodiments, the lens system of a sensor may be configured for a specific eye part. In embodiments, the lens system of a sensor may be adjustable in order to access any one or more eye part in combination with each other. In embodiments, the dedicated processor may be configured to operate with more than one sensor data collection system and more than one sensor data analysis system. In a non-limiting example, the iris scan and the corneal mapper may use the same sensor to obtain data about the iris and the external surface of the cornea, respectively. In the same manner, the macular condition measurement system and the blood pressure measurement system may be realized with the same optical sensor, but the data obtained may be processed by different applications, while utilizing a shared processor. In embodiments and in FIG. 2A, the blood pressure sensor 274 may examine other parts of the user's face, to capture dynamic variations in skin deformation due to pulsating blood passing through veins and capillaries.

In embodiments and in FIG. 3D, the systems and methods described herein may comprise a user interface with a Direct Access Sensor Suite 340. The sensors in the sensor suite may comprise any or all of the sensors recited in FIG. 1B for vision correction prescription system, or any or all of the sensors recited in FIG. 2B for the health assessment system, or the like. The sensor suite for vision correction may comprise any or all of a contact lens auto-refractor 271, which is shown at 341 in FIG. 3D, a corneal mapper 272, shown at 342, a glasses auto refractor 273 shown at 343, a glasses frame fitter 374, shown at 344, an iris scanner 276 shown at 345, or the like. In embodiments, the sensors deployed in a single or multiple optical access systems, the front of which is shown in FIG. 3D. The number of visible optical access ports may vary according to the implementation of the manufacturer of the kiosk. In embodiments, and in FIG. 2B, the sensor suite for a health assessment system may comprise a glaucoma sensor 271, which may be mounted at 341 in FIG. 3D, a diabetes sensor 272, shown at 342, a macular condition sensor 273, shown at 343, a blood pressure/pulse rate sensor 274, shown at 344, an Alzheimer's sensor 275, shown at 345, or an iris scanner 276, shown at 346. In embodiments, the iris scanner 276 may be located at the top center of the user Interface in FIG. 3D, at 340. In embodiments, an access jack 347 may be incorporated to accommodate external, alternate sensors such as, but not limited to, an electronic stethoscope or a direct blood glucose measurement sensor, not shown.

In embodiments and in FIG. 3E, a single optical lens system may sense multiple characteristics of the various parts of an eye in a single image and pass the image to a number of different CCD devices for simultaneous analysis according to the principles and methods used for each type of analysis selected. Such analysis may be implemented according to image-splitting and separation methods well-known in the optical arts. In embodiments, fewer optical access modules may be used for data acquisition.

In embodiments, the systems and methods disclosed herein may comprise an assembly for a multiple sensor suite 370. The assembly may comprise an adjustable lens focusing system 371. The adjustable lens focusing system 371 may be controlled by a lens adjustment system 372. The lens adjustment system 372 may receive inputs from a suitable controller processor 352, or a separate processor 351. The assembly may receive inputs from a user's eye 361, or specifically a user's cornea 362. A beam splitter 373 may be used to separate the input received from into multiple components via partially silvered mirrors 380, via well-known techniques in the optical arts. The input is split into 2 separate beams at 382 and 383. The beams may be directed towards CCD sensors for detection and conversion into a digital image, as shown at 374 and 376. The digital image data may then be delivered to special processors 375 and 377 for analysis and rendering. The results may be delivered to the processor 351 for further manipulation, storage in RAM 353 or ROM/HD memory 354. An optional third beam may also be split via the addition of another half silvered mirror, not shown. The third beam may be directed to another CCD device at 378, and its digital image may then be delivered to a suitable processor 379 for analysis and delivery to the processor 351. In embodiments, each sensor may be configured with an internal target for a user to look at. The adjacent cameras may take images of the eye and when the user eyes fit the observational position, indicating that the user is looking at the internal target, the sensor may then be activated to perform its data acquisition process.

In an embodiment, the CCD sensors may have optical filters installed on the surface, to filter for desired wavelengths. These filters, which are located between the beam splitter output and the input to the CCD, not shown, permit detection of desired wavelengths and reduce the amplitude of out-of-band wavelengths. The choice depends of the function of the sensor. Results may be displayed to the user on display 350. The input for sensor selection function may be done via the input control device at 360.

In embodiments, a single sensor may be used for multiple functions. In embodiments, multiple functions for measuring the cornea shape and determining the eyeglasses fitting dimensions may be implemented via a three-dimensional surface scanner system. One such 3D scanner, made by DotProduct, Inc., uses structured light to illuminate a surface such as the cornea, or the face and eyes of a person. The structured light may consist of an array of very small, closely spaced circular dots or other structural elements that impinge on the surface of interest. Typically infrared light is used, and the image capture device has a filter to allow passage of infrared and exclude the rest of the light spectrum. The camera captures the image on the dots on the surface, and via various image-processing techniques involving measurement of the shape of the dot and its size, as well as the spacing between adjacent dots, determines the distance from the structured light source to each dot on the surface. The dot pattern array spacing for a flat surface is known in advance; as such, the X, Y, and Z dimensions of the surface may be calculated based on the deviation of dot locations on an actual, curved surface from the spacing that would have been present on a flat surface. With sufficiently small dot pattern spacing, the cornea can be mapped with enough precision to enable preparation of a contact lens. Similarly, the important parameters for eyeglasses fitting can be determined, such as the spacing between the two eyes, pupil to pupil, the width of the face, the location of the ears, and the like. Close-range 3D scanners are known in the high precision measurement arts for inspection of parts, and the like.

In embodiments, the user's image as captured by the 3D scanner may be displayed for real-time viewing by the user. The user may select a type of frame from a menu displayed on the user interface display screen. The selected frame design and dimensional parameters may be adjusted to fit the dimensions determined by the 3D scanner for the user's face, eye, and ear locations. The selected frame with proper dimensions can be modeled in 3 dimensions, and an image of the selected frames may be displayed to the user. In addition, an image of the frames may be overlaid on the current image of the user as captured in real-time by the scanner, via well-known augmented-reality (“AR”) techniques. In this manner, the user may see exactly how the selected frame will look on his face. The user may move his head around and see the frames from a variety of look angles, exactly as he would see it if he had real frames on while in a store. The AR technique may generate a model of the head as determined from instant samples of the user's head, face, eyes and ears, and generate anchor points for fixing the selected and dimensioned frames to the head model. These anchor points may comprise the pupil of the eye locations, top edge of ear joint to head locations, bridge of nose, or the like or any combination thereof. Once the anchor points are selected, for example, by an algorithm operating in a processor, the head model and the frame model may be joined. Location of the head as determined by the scanner may then be used to determine head position display of the joined model in the display image. Since the frame model is now anchored to the head, the anchored frame image will move with the instant image of the user's head/face, generating the effect of a virtual mirror for eyeglasses fitting.

Several systems and methods for fitting an eyeglasses frame to a user exist in the art and are commercially available. One such product is the MVTec Software GmbH/Munich HALCON software image processing for eyeglasses system. The MVTec Software allows for sample-based identification, 3D surface comparison, 3D object processing, and photometric stereo surface inspection. Other methods known to the art can be found in US 2009/0051871 “Custom Eyeglass Manufacturing Method” by Dreher et al., which analyzes multiple images captured from a digital camera in order to identify the relation of specific points of interest on a frame to outfit eye glasses. This patent application is incorporated by reference herein, in its entirety. The '871 uses an image processer to determine pupil position relative to a spectacle frame captured in front and side images. Another method for fitting an eyeglasses frame to a user is provided by U.S. Pat. No. 6,682,195 “Custom Eyeglass Manufacturing Method” by Dreher et al., which utilizes a wavefront measuring device with multiple cameras directed at a user's face and applies the measurements to a mold of a patient's head. The images are then processed by a computer to determination the location of key measurements such as pupils, center of pupils, pupil distance, width of face, ear location, distance of corneal apex from the wavefront machine, and others. These methods and systems may be incorporated into a system as described herein to provide eyeglass fitting capability and the entire disclosure of each is incorporated by reference herein, in its entirety.

In embodiments, the 3D scanner may be used as an indicator of relative head positioning, via eye detection. The multiple centering cameras shown in FIG. 5 at 511 may be replaced by a single 3D scanner which can determine where the user's head/face is relative to a sensor that has been selected, and guidance indicators as shown at 411 in FIG. 4A can be used to help the user move his head into a proper position for the examining sensor. Often the examining sensor will have additional indicators built into the main sensor element 410 to indicate when the user has properly positioned his head. In embodiment and in FIG. 6A and FIG. 6B, the control system for the transport mechanisms may perform additional fine-adjustments to achieve the alignment needed.

The 3D scanner may be located at any of the locations cited and shown in FIG. 3B, 3C, or 3D. The only information required in order to coordinate and calibrate measurements will thus be the spatial relationships between the 3D scanner and the various other sensor systems. In embodiments, the 3D scanner may be a separate module installed in the carousel system as well.

In embodiments the assessment systems may be integrated with a plurality of subsystems. For example, in embodiments, a contact lens prescription generator may be supplied, along with a corneal mapping unit, to provide both the correction prescription and a surface map of the cornea to aid the making of a contact lens that fits the user properly. The original map may be reduced to a mathematical model via various methods shown in the literature. Such mathematical models may enable a custom-made lens to be produced on a mold made from the mathematical model. Optionally, an eyeglass prescription generator may be included, or may be offered independently in a separate stand-alone system. Optionally, an eyeglass frame fitting analyzer may be included with the eyeglass prescription generator. Options for frame choice may be shown on a user display. In embodiments, the system may generate prescriptions for bifocals, trifocals, continuously variable corrections, sunglasses, and the like. Measurements of body parameters for eyeglasses fittings may be obtained from images of the user's face and head, taken by cameras that may also be used for sensor alignment to the user's eyes. Examples of the functionality of the prescription generator may include, but is not limited to, dispensing a printed prescription for the user or forwarding the prescription directly to a contact lens provider. The user may make a payment for all services via a credit card reader system or other payment system known to the art, as installed in the main housing. One such payment system is the VenTek International Corp., which may provide PCI (Payment Card Industry) certified payment systems with automated pay stations and PCI PA-DSS (Payment Application Data Security Standard) compliant revenue collection from the vision and health assessment systems disclosed herein. Payment Cards may include both credit cards and other kinds of cards as may be issued by insurance companies, such as those which provide coverage for health assessment screening and/or vision prescription and other forms of vision care. In addition to various embodiments of point of sale payment systems, which are incorporated herein by reference in their entirety, payment system management programs may also be incorporated. One such management system is the venVUE, which is a web-based platform. It provides real-time pay station status, remote active and passive monitoring, remote pay station configuration and report generation for status, operational statistics, revenue collection and reconciliation.

In embodiments, the sensor suite may comprise a contact lens auto-refractor. The auto-refractor may be any one of the several auto-refractors known to the art and commercially available, such as, but not limited to, The Canon RK-F1 Full Auto Refractor-Keratometer, the Marco Nidek ARK 530A Auto Refractor Keratometer, the Tomey RT-7000 Auto Refractor/Topographer, the Right Medical Speedy-K Auto Refractor Keratometer, and the like. Several eyeglasses auto-refractors are also known to the art. Once such auto-refactor is the CHAROPS CRK7000 Autorefractor/Keratometer. The CRK7000 uses two mire rings and two LEDs to provide corneal curvature radius and corneal refractive power.

In embodiments, the sensor suite may comprise corneal topography and imaging sensors in order to examine a user's corneas to verify that the user may be fitted with a contact lens. The corneal topography and imaging sensor may be one of the several technologies known to the art and commercially available. In embodiments, the sensor suite may include a sensor such as, but not limited to, the Scout Keratron Corneal Topographer, from Eyequip, which is a portable topographer for corneal topography and imaging. The Scout Keratron may be adapted to function as an affixed component of a sensor suite. Alternatively, in embodiments, the sensor suite may comprise the Orbscan Hz Corneal Analysis System by Bausch & Lomb, which is a multidimensional diagnostic topography system that maps and analyzes elevation and curvature measurements of the entire anterior and posterior surfaces of the cornea. The Orbscan II corneal topography system may also perform pachymetry measurements to determine the thickness of the cornea in a non-contacting method. Such a method may be useful for glaucoma testing. In other embodiments, the sensor suite may comprise the Pentacam, manufactured by Oculus, which is a combined device using a slit illumination system and a Scheimpflug camera which rotates around the eye. In embodiments, the systems and methods disclosed herein may comprise software configured to assess the health of the cornea and the likelihood that a user's eye(s) may be fitted with a suitable contact lens. This software is designed to detect anomalies in the shape or surface or interior of the cornea. Once the cornea is judged to be able to accept a contact lens, the auto-refractor can determine the proper correction prescription. A prescription can be written for any kind of contact lens, including the two most popular types: rigid gas permeable (hard) and silicone hydrogels (soft).

In embodiments, a specialized sensor may be employed to measure and map the cornea so that the anterior surface of a contact lens can be custom-made to fit each eye. For example, a three dimensional scanners such as the above mentioned DotProduct, though not limited to such products, may be used to measure and map a cornea for contact lens customization.

In embodiments, a specialized sensor may be employed for diabetes testing. There are several products and methods known to the art and commercially available for diabetes testing. One such product is the CLEARPATH DS-120, a non-invasive instrument for measuring the level of blood glucose in the fluids and structures of the eye. The product recently was approved by the Food and Drug Administration of the U.S. Government with a 510(k) clearance and is available from Freedom Meditech, Inc. It identifies levels of elevated Advanced Glycosoloated End Products [“AGEs”] by measuring the intensity of fluorescence and scattering of light in the lens during a brief scan. In embodiments, other sensors to determine glucose non-invasively may be used. One such sensor is the Dione bidirectional sensor, produced by Lein Applied Diagnostics. The Dione is a bidirectional sensor which is a compact and affordable source/detector module that can be used as a scanning or static device, using confocal micrology technology. The Lein technology may be used to determine distance and position, thickness, as well as refractive power.

In embodiments, a specialized sensor may be employed for blood pressure and pulse rate detection. Such methods are readily known to the art. One such method is provided by Poh et al. in their article “Non-contact, automated cardiac pulse measurements using video imaging and blind source separation,” printed in Optics Express, Vol. 18, Issue 10, pp. 10762-10774 (2010). Poh et al. used automatic face tracking along with blind source separation of color channels into independent components, then used Bland-Altman and correlation analysis to correctly predict physiological readings from a user's facial movements.

In embodiments, a sensor may be employed to determine macular condition of a user's retina. Such sensors and methods are readily known to the art. One such sensor is the SECO International Inc. EasyScan zero-dilation retina. This camera may provide an image of the retina based on Scanning Laser Opthalmoscope technology (“SLO”). SLO uses horizontal and vertical scanning mirrors to scan a specific region of the retina and create raster images that may be viewable.

In embodiments, sensors may be employed to determine retinal circulatory physiology. Such sensors and methods are known the art. The EasyScan and the abovementioned CLEARPATH DS-120 may also be used to image blood vessels in the retina. Analysis of these images by a suitable program can identify abnormalities in the size and shape of the blood vessels, which may indicate existence of a number of physiological readings, such as hypertension.

In embodiments, the health assessment system may be configured to provide additional testing subsystems as described herein. These additional testing subsystems may be added any configuration for vision screening, supplied individually, or used in combination with other subsystems.

In embodiments, eye examination sensors for the various assessment subsystems may each be mounted on a carousel wheel that may be rotated to present a particular assessment subsystem sensor to the face of the user. The wheel may be located behind a viewing panel that opens to the user when activated. The particular assessment subsystem senor is extended from the wheel so that it may be brought closer to the user's face, and available directly to the user's eyes. In another embodiment, the sensors may be stored in a file-cabinet like structure, and conveyed from that structure to the front of the housing, where the sensor may be positioned by automatic sensing of the user's face and eye locations. Other embodiments for storage and retrieval are also feasible.

Additional details of the mounting and transport systems 111 and 211 in FIG. 1A and FIG. 2A respectively are shown in FIGS. 4A, 4B, and 5. In embodiments and in FIG. 4A, the systems and methods disclosed herein may comprise a mounting and transport system for conveying various sensors to the examination window and in proximity to the user's eyes. The overall system is referred to as the Visual System User Interface Assembly 400. The system may comprise a wheel box with the sensor suite contained therein, at 401. The system may further comprise a height adjuster 402 to bring the selected sensor into alignment with the location of the user's eyes. A depiction of a user's head is shown at 413 and 414, showing different height elevations for different users. Elevation may be controlled by the control system 155 for the prescription system of FIG. 1A or 255 for the health assessment system of FIG. 2A. The height adjustment may be accomplished manually by user input to the user input system 120 or 220. It may also be accomplished automatically by use of cameras and software configured to look for eye shapes as the elevation adjust 402 moves upwards from a rest position. The range of vertical motion of the wheel box 401 is shown at 403. The wheel box 401 comprises a rotating platter on which various sensors are affixed as shown at 407 and 409. In embodiments the system may comprise multiple sensors 408. The system may comprise is a main sensor 410 for performing the analysis. The system may comprise two cameras at 409, camera 1 and camera 2, which may be used to locate the user's eyes and create a feedback system of indicators around the periphery of the main sensor 410 to indicate when the user has positioned his eye in the proper place. Such eye alignment sensors 411 may be incorporated with each separate testing sensor in the sensor suite 407 as may be desired or necessary. When the desired sensor for a particular function is selected, the wheel may rotate to bring the selected sensor into proper position at the examination window 405. The sensor system may be extended from its location on the wheel, to bring the sensor into closer proximity with the user's eye[s] as shown at 412. In embodiments, the system may comprise a head supporting system, which may extend from the face of the housing in a recessed position or in an extended position 406, permitting the user to rest their chin on the support system, and get into proper position for a chosen sensor to examine their eyes.

The systems and methods disclosed herein may provide for corneal topography and imaging, such as before any auto-refracting is done, where the user's corneas are examined and where it is verified that they can be fitted with a contact lens. Software may be configured to assess the health of the cornea and the likelihood that the user's eye(s) can be fitted with a suitable contact lens. This software may be designed to detect anomalies in the shape or surface or interior of the cornea. Once the cornea is judged to be able to accept a contact lens, the auto-refractor can determine the proper correction prescription. A prescription may be written for a variety of different kinds of contact lens, such as including the two most popular types: rigid gas permeable (hard) and silicone hydrogels (soft).

The systems and methods disclosed herein may provide for corneal mapping for the contact lens' anterior surface, where a corneal spline generator may utilize a spline surface algorithm for reconstruction of the corneal topography from a video keratographic reflection pattern, or an iteratively re-weighted bi-cubic spline representation of corneal topography. Using a comparison to standard models, corneal shaping for adequate tear flow and hydration, and the like may be implemented. Additional software may be used to modify the first estimate of the corneal shape and spline rendering, to accommodate the need for proper tear flow and eliminate any pockets that would preclude irrigation of the cornea by tears. A corneal topography system may also perform pachymetry measurements to determine the thickness of the cornea in a non-contacting method.

Several corneal mapping sensors and methods are available to measure the anterior surface of a user's cornea for several purposes, such as for contact lens prescription. One such method is detailed by Mark A. Halstead et al. in their paper “A Spline Surface Algorithm for Reconstruction of Corneal Topography from a Videokeratographic Reflection Pattern.” Halstead's method uses an iterative algorithm in order to output a piecewise polynomial description of a simulated corneal surface in order to recover the three dimensional shape of a cornea from a videokeratograph image. Another method known to the art is by Zhu et al., detailed in their paper “Iteratively re-weighted bi-cubic spline representation of corneal topography and its comparison to the standard models.” Zhu's method represents the corneal anterior surface using radius and height data taken from a TMS-2N topographic system and simulates visual performance using a general quadratic function, a higher order Taylor polynomial approach, and an iteratively re-weighted bi-cubic spline method.” Similarly, U.S. Pat. No. 5,452,031 “Contact lens and a method for manufacturing contact lens” teaches a method of manufacturing a contact lens using computer implemented spline approximation of corneal topology. This method uses piecewise polynomials in order to generate a smooth measuring surface. Additional software may be used to modify the first estimate of the corneal shape and spline rendering, to accommodate the need for proper tear flow and eliminate any pockets which would preclude irrigation of the cornea by tears
