Adaptive corrective spectacles, and method for controlling the spectacles

Abstract

In order to control adaptive corrective spectacles, a controller commands, in a first operating mode, on the basis of sensor signals, a change in at least one optical effect of the spectacles in order to correct defective vision. In a second operating mode, the controller commands, on the basis of the same sensor signals, no change or a reduced and / or delayed change in the at least one optical effect of the spectacles and, if a non-stationary state of a wearer of the spectacles is determined, switches from the first operating mode into the second operating mode and / or, if a stationary state of a wearer of the spectacles is determined, switches from the second operating mode into the first operating mode. Additionally or alternatively, the controller comprises a data-processing process based at least partially on machine learning, wherein, in the first operating mode, a change in the at least one optical effect of the spectacles is commanded on the basis of sensor signals which depend on a detection of the surroundings of the spectacles and / or on a detection of a wearer of the spectacles. The invention also relates to adaptive corrective spectacles.

[0003] Description

[0004] Adaptive corrective glasses and methods for controlling the glasses

[0005] The present invention relates to an adaptive corrective lens and a control of the corrective lens.

[0006] Corrective lenses have optical effects to correct refractive errors. With adaptive corrective lenses, these optical effects can be changed reversibly.

[0007] The object of the present invention is to improve adaptive corrective eyeglasses or their use.

[0008] This problem is solved by a method with the features of claim 1 and / or 3. Claim 6 protects an adaptive corrective lens that is controllable according to a method described herein, in particular that is controlled at least temporarily, or that is equipped or used for this purpose, in particular by hardware and / or software, in particular by control or programming technology. The dependent claims relate to advantageous embodiments.

[0009] According to one embodiment of the present invention, in a further development, a control system for adaptive corrective eyewear in a first operating mode, preferably electrically, commands, and in particular causes to effect, a preferably predetermined change in at least one optical effect, in one embodiment refraction or refractive power, (of one or both lenses) of the eyewear for correcting a refractive error, in one embodiment presbyopia and / or ametropia, in particular hyperopia and / or myopia and / or astigmatism, wherein the present invention is particularly advantageous for corrective eyewear (for correcting) presbyopia, without being limited thereto.

[0010] The change can be achieved in particular through electroactivated material of the corresponding spectacle lens and / or an electroactivated actuator for 120772P1423PC 2 / 20 Rodenstock GmbH

[0011] P2320 PCT

[0012] Deformation and / or movement of the corresponding spectacle lens is effected, wherein commanding a change can include commanding corresponding control signals, preferably currents. In one embodiment, the corrective spectacle is an electro-adaptive corrective spectacle.

[0013] According to one embodiment of the present invention, in a further development the control system is commanded, preferably electrically, in a second operating mode, based on, in particular as a result of or when, the same sensor signals are present.

[0014] - no change or

[0015] - a reduced and / or (temporally) delayed change in at least one optical effect of the glasses, whereby the control

[0016] - switches from the first to the second operating mode when, in one implementation by the controller, a non-stationary state of a wearer of the glasses is detected; and / or

[0017] - switches from the second to the first operating mode when, in one version by the control system, a stationary state of a wearer of the glasses is detected.

[0018] This advantageously reduces or avoids changes in the optical effect, particularly high-frequency changes, during changes in the viewing distance or focus of the spectacle wearer, or the like, which could otherwise lead to impairments for the spectacle wearer due to changing (visual impairment) corrections.

[0019] In particular, focusing can occur or the optical power of the glasses can vary in the first operating mode, while no focusing occurs or the optical power of the glasses remains constant in the second operating mode. Switching from the first to the second operating mode can preferably occur if the change in optical power determined based on the sensor signals, which would be required for focusing, remains below a threshold value, in particular below a threshold value of 0.5 diopters or 0.25 diopters, preferably 120772P1423PC 3 / 20 Rodenstock GmbH

[0020] P2320 PCT below a threshold of 0.1 diopters and particularly preferably below a threshold of 0.05 diopters. Advantageously, this prevents constant refocusing due to small variations, even though the user's gaze direction is in a quasi-stationary state.

[0021] Switching from the first to the second operating mode can preferably be accompanied by refocusing, with the focus then remaining constant in the second operating mode. Similarly, switching from the second to the first operating mode can occur if the change in optical effect, determined based on the sensor signals and required for focusing, reaches or exceeds the aforementioned threshold.

[0022] Preferably, the switching from the first to the second operating mode described above can only occur if the aforementioned threshold value is undershot for a predetermined time. Advantageously, this prevents very frequent switching back and forth between the first and second operating modes. The predetermined time can preferably be more than 0.05 s, more preferably more than 0.1 s, more than 0.5 s, or more than 1 s.

[0023] Preferably, switching from the second operating mode to the first operating mode can occur if the aforementioned threshold is reached or exceeded for a predetermined time. Particularly during rapid head movements, the sensor signals can cause the control unit to change the focus at short intervals by the threshold or a multiple thereof, which can lead to a distracting focus change for the user. Especially during head movements and rapid changes in the user's gaze direction, the glasses may remain in the second operating mode, as the user's visual experience in these cases is not based on a focused image of the surroundings. The predetermined time can also preferably be more than 0.05 s, more preferably more than 0.1 s, more than 0.5 s, or more than 1 s. 120772P1423PC 4 / 20 Rodenstock GmbH

[0025] In one embodiment, in a further development, the non-stationary state of the wearer of the glasses comprises a state in which a distance to a viewed or focused area of ​​the environment ("viewing distance") or focus of the wearer of the glasses changes, in particular at least with a predetermined minimum rate of change, and / or the stationary state of the wearer of the glasses comprises a state in which a viewing distance or distance to a viewed or focused area of ​​the environment or focus of the wearer of the glasses does not change, in particular at least for a predetermined minimum time, or changes at most with a predetermined maximum rate of change, which is preferably less than the minimum rate of change, or a state in which the wearer of the glasses fixes an area of ​​the environment, in particular for at least a predetermined minimum time and / or at most with a predetermined maximum rate of change, or is determined accordingly.

[0026] Additionally or alternatively, the non-stationary state in one embodiment may comprise a state, in a further development, in which the wearer of the glasses moves, in particular their head and / or eye(s), at least at a predetermined minimum speed and / or minimum acceleration, and / or an environment (of the wearer) of the glasses changes at least at a predetermined minimum rate of change, and / or the stationary state may comprise a state, in a further development, in which the wearer of the glasses does not move, in particular for at least a predetermined minimum time, or moves at most at a predetermined maximum speed or acceleration, which is preferably less than this minimum speed or acceleration, and / or an environment (of the wearer) of the glasses does not change or changes at most at a predetermined maximum rate of change, which is preferably less than this minimum rate of change.As can be seen particularly from this, the stationary state can also be a quasi-stationary state.

[0027] By determining the stationary state, when a viewing distance or distance to a viewed or focused area or focus of the eyeglass wearer does not change for at least a specified minimum time or 120772P1423PC 5 / 20 Rodenstock GmbH

[0028] In the P2320 PCT, if the eye position is changed at most with a predefined maximum rate of change, or if the wearer of the glasses fixates on an environmental area for at least a predefined time with at most a predefined maximum variation, adaptation during a gaze shift can be suppressed in one implementation. Additionally or alternatively, a time delay can also be implemented, particularly through a correspondingly predefined minimum time, or adaptation can only occur after a kind of latency period following a gaze shift.

[0029] In one implementation, the non-stationary state and / or the stationary state is based on

[0030] - a determined eye position and / or movement of one or both eyes; and / or

[0031] - a determined eyelid position and / or movement of one or both eyes; and / or

[0032] - a determined head position and / or movement; and / or

[0033] - a determined pupil position and / or movement of one or both eyes; and / or

[0034] - a determined pupil size and / or pupil size change of one or both eyes; and / or

[0035] - a determined gaze direction and / or change in gaze direction of one or both eyes; and / or

[0036] - a determined eye focus and / or eye focus change of one or both eyes; of the wearer; and / or based on

[0037] - determined by the glasses' detection of an environment and / or changes in the environment.

[0038] These parameters, preferably a combination of two or more of them, allow for a particularly advantageous, especially quick, precise, and / or reliable determination of a wearer's (in)stationary state of the glasses. 120772P1423PC 6 / 20 Rodenstock GmbH

[0039] P2320 PCT

[0040] In addition to or as an alternative to the aspect of the second operating mode, according to one embodiment of the present invention, the control system comprises data processing that is at least partially based on machine learning and, in the first operating mode, and in a further development also in the second operating mode, commands a change in the at least one optical effect of the glasses based on sensor signals which depend on the detection of an environment of the glasses and / or the detection of a wearer of the glasses.

[0041] By means of data processing or control based at least partially on machine learning in conjunction with sensor signals that depend on the detection of a wearer of the glasses or, particularly advantageously, on the detection of the environment of the glasses, and most advantageously in conjunction with sensor signals that depend on both the detection of the environment of the glasses and the detection of a wearer of the glasses, a particularly advantageous, in particular fast, precise and / or reliable, adaptation of the corrective glasses can be realized.

[0042] In one version, sensor signals are included on the basis of which the control in the first and / or second operating mode commands a change in at least one optical effect of the glasses and / or determines the non-stationary and / or stationary state of the wearer of the glasses:

[0043] - Sensor signals from at least one optical sensor, in particular one arranged on the glasses, in particular at least one camera and / or at least one brightness sensor; and / or

[0044] - Sensor signals from at least one acoustic sensor, in particular one arranged on the glasses; and / or

[0045] - Sensor signals from at least one acceleration and / or position sensor, in particular one arranged on the glasses; and / or

[0046] - Sensor signals from at least one distance sensor, in particular one arranged on the glasses and / or contactless; and / or

[0047] - Sensor signals from at least one electromyographic sensor, in particular one arranged on the glasses; and / or depend on 120772P1423PC 7 / 20 Rodenstock GmbH

[0048] P2320 PCT

[0049] - a determined eye position and / or movement of one or both eyes; and / or

[0050] - a determined eyelid position and / or movement of one or both eyes; and / or

[0051] - a determined head position and / or movement; and / or

[0052] - a determined pupil position and / or movement of one or both eyes; and / or

[0053] - a determined pupil size and / or pupil size change of one or both eyes; and / or

[0054] - a determined gaze direction and / or change in gaze direction of one or both eyes; and / or

[0055] - a determined eye focus and / or eye focus change of one or both eyes; of the wearer; and / or

[0056] - a detection of an environment and / or environmental change by the glasses.

[0057] These sensor signals, preferably a combination of two or more of them, can be used to control a (suitable or advantageous) change in at least one optical effect of the glasses, particularly advantageously, especially quickly, precisely, and / or reliably. Furthermore, these sensor signals, preferably a combination of two or more of them, can be used to determine a (stationary) state of a wearer of the glasses, particularly advantageously, especially quickly, precisely, and / or reliably.

[0058] For example, rapid and / or large movements and / or changes can result in unsteady states, while absent or slow and / or small movements and / or changes can result in stationary states. In certain states, such as downward-looking eyes, determined, for example, by eye and / or eyelid position and / or movement, the control system can, for example, predict reading or other viewing of a nearby object and the optical effect. 120772P1423PC 8 / 20 Rodenstock GmbH

[0059] Adjust the P2320 PCT accordingly. Similarly, for example, with forward-facing eyes and / or a rapidly changing environment, the control system can predict walking or other movement by the wearer and adjust the optical effect accordingly.

[0060] If, in an embodiment, the sensor signals on the basis of which the control in the first and / or second operating mode commands a change in the at least one optical effect of the glasses and / or the non-stationary and / or stationary state of the wearer of the glasses is determined, depend on (eye and / or lid and / or pupil positions and / or pupil sizes and / or gaze directions and / or eye focuses and / or eye and / or lid and / or pupil movements and / or pupil size and / or gaze direction and / or eye focus changes of) both eyes of the wearer, a (suitable or advantageous) change in the at least one optical effect of the glasses can be commanded particularly advantageously, especially quickly, precisely and / or reliably, and / or a (non-)stationary state of a wearer of the glasses can be determined particularly advantageously, especially quickly, precisely and / or reliably.For example, in the case of eye movements in the same direction, a following movement to optically fixate on an area of ​​the environment can be predicted if the carrier (head) and / or area of ​​the environment is moving, and in the case of eye movements in opposite directions, a convergence movement to optically fixate on a closer area of ​​the environment can be predicted, and the optical effect can be adapted accordingly.

[0061] As already mentioned, it can be particularly advantageous to use data processing based at least partially on machine learning to control the glasses using sensor signals that depend on the detection of the glasses' surroundings, and even more advantageously, also based on sensor signals that depend on the detection of the wearer. For example, an acoustic environment can be used to predict a conversation and, based on this, a short eye-level distance to a conversation partner, and the optical effect can be adjusted accordingly. 120772P1423PC 9 / 20 Rodenstock GmbH

[0062] P2320 PCT

[0063] The data processing, which is at least partially based on machine learning, is (pre)trained in one version based on different people.

[0064] This allows the method or the glasses to be used advantageously in a wider variety of situations. Additionally or alternatively, the data processing, which is at least partially based on machine learning, can be (further) trained in a specific version based on the wearer of the glasses. This allows the method or the glasses to be used particularly advantageously in situations frequently encountered by that wearer.

[0065] According to one embodiment of the present invention, an adaptive corrective eyeglass has a control unit, wherein the corrective eyeglass, in particular the control unit, is equipped or used in a hardware and / or software, in particular control or programming, configuration for carrying out a method described herein.

[0066] In one version, the corrective glasses or control unit has a first operating mode, as described here, in which the control unit, based on sensor signals, commands a change in at least one optical effect of the glasses to correct a refractive error, in one version presbyopia and / or ametropia, in particular hyperopia, myopia and / or astigmatism.

[0067] In a further education course, the corrective glasses have a sensor arrangement with one or more sensors that output the sensor signals described here, or are set up or used for this purpose.

[0068] In one version, the corrective glasses or control unit features:

[0069] - a second operating mode, or the one described here, in which the control system, based on the same sensor signals, commands no change or a reduced and / or delayed change to at least one optical effect of the glasses; and

[0070] - Means that switch the control from the first to the second operating mode when a non-stationary state of a wearer of the glasses is detected 120772P1423PC 10 / 20 Rodenstock GmbH

[0071] P2320 PCT will, and / or switch from the second to the first operating mode when a stationary state of a wearer of the glasses is detected, or are set up or used for this purpose; on.

[0072] Additionally or alternatively, the corrective glasses or control unit in one version includes data processing that is at least partially based on machine learning, wherein the control unit, in particular the data processing unit, includes means that command, or are equipped or used for, a change in the at least one optical effect of the glasses in the first operating mode based on sensor signals that depend on the detection of an environment of the glasses and / or the detection of a wearer of the glasses.

[0073] A means according to the present invention can be configured as hardware and / or software, in particular comprising at least one processing unit, preferably a microprocessor unit (CPU), graphics processing unit (GPU), or the like, preferably connected to a storage and / or bus system via data or signals, and / or comprising one or more programs or program modules. The processing unit can be configured to execute instructions implemented as a program stored in a storage system, to acquire input signals from a data bus, and / or to output signals to a data bus. A storage system can comprise one or more, in particular different, storage media, in particular optical, magnetic, solid-state, and / or other non-volatile media. The program can be configured to embody the methods described herein.is able to execute, so that the processing unit can carry out the steps of such procedures and thus, in particular, control adaptive corrective glasses.

[0074] In one embodiment, one or more, in particular all, steps of the process are fully or partially computer-implemented, or one or more are 120772P1423PC 11 / 20 Rodenstock GmbH

[0075] P2320 PCT several, in particular all, steps of the procedure are carried out fully or partially automatically, in particular by the glasses or control system.

[0076] In one version, one or more of the specified sizes mentioned here are variably adjustable, preferably by the manufacturer and / or by the wearer of the glasses.

[0077] As already explained, one aspect of the present invention lies in improving the determination of eye distances, preferably when wearing glasses in uncontrolled environments such as outdoors or in everyday life, in order to control adaptive glasses (lenses). According to one aspect of the present invention, a (correction) algorithm is provided for the adaptive glasses (lenses) that is comfortable for the user to wear, in particular without undesirably abrupt changes in visual acuity, but also without undesirably slow adjustment.

[0078] As already explained, one aspect of the present invention lies in determining the viewing distance by capturing one or more physiological parameters and / or environmental values ​​and / or combining such measured values ​​with analytical and / or machine learning methods to determine a viewing distance.

[0079] Advantageously used physiological parameters may include, in particular:

[0080] • Electromyography (MCG) of the eye muscles. This is particularly advantageous because the nose and ear rest allows for natural positioning of the electrodes on the skin, for example when they are integrated directly into the nose pads and the temples of the glasses;

[0081] • Determining head movements, in particular by means of gyro sensor(s) in the socket;

[0082] • Determining the pupil position and / or pupil diameter, in particular by means of light sources, especially LEDs, in one version, IR LEDs, and / or by means of cameras, in particular IR cameras, or other 120772P1423PC 12 / 20 Rodenstock GmbH

[0083] P2320 PCT optical sensors, wherein (IR)LEDs or other light sources may be used in particular to illuminate the pupil and / or to generate a controlled reflection for positioning;

[0084] • Determining the eyelid position, especially using MCG or optical methods;

[0085] • Measuring object distances, in particular by means of one or more forward-facing distance sensors and / or capturing the field of view with a forward-facing camera;

[0086] • Acoustic measurement using one or more microphones in the housing to enable acoustic localization;

[0087] • Brightness sensor in the socket to distinguish pupil diameter changes due to convergence and ambient light.

[0088] Particularly advantageous combinations of physiological parameters and their consideration in the adaptation of electronic spectacle lenses can include, in particular, the following:

[0089] - Using the MCG, it is possible to distinguish between symmetrical eye movements (following movements) and opposing convergence movements of the eyes, and to derive a gaze distance from this;

[0090] - The MCG can be used to advantageously measure pupil diameters, and in one version contact lenses and / or IOL electrodes can be used additionally or alternatively;

[0091] - During an active head or eye movement, the

[0092] The adaptation of the electric glasses is changed; preferably, readjustment is only performed during a quasi-standstill to avoid rocking;

[0093] Determining the current head position / tilt improves the estimation of viewing distance; for example, a tilted head makes looking at near objects more likely. In particular, machine learning makes it possible to determine plausible "viewing situations" with typical viewing distances from acceleration and / or position sensors worn on the frame, such as walking, running, lying down, standing, sitting, driving, or the like; 120772P1423PC 13 / 20 Rodenstock GmbH

[0094] P2320 PCT

[0095] Pupil diameter and convergence are physiologically linked; therefore, measuring pupil distance and diameter improves the accuracy of distance measurement;

[0096] - Distinguishing between different types of eye movements, for example fast saccades from slower tracking movements, can improve distance estimation from PD;

[0097] - Determining the eyelid position can allow for a more accurate determination of the gaze direction / distance;

[0098] - Forward-facing distance sensors can provide possible candidates for plausible viewing distances, with the selection of the correct distance preferably then being made in combination with other measurements;

[0099] - Forward-facing cameras and / or microphones capture the "scene" in front of the eyes and provide information about interesting / likely viewed objects and their corresponding distances.

[0100] Further advantages and features will become apparent from the dependent claims and the exemplary embodiments. These are shown, in part schematically:

[0101] Fig. 1: an adaptive corrective spectacle according to an embodiment of the present invention; and

[0102] Fig. 2: a method for controlling the adaptive corrective glasses according to an embodiment of the present invention.

[0103] Fig. 1 shows an adaptive corrective eyeglass 1 according to an embodiment of the present invention with a control 2 which in one embodiment has data processing based at least partially on machine learning.

[0104] The glasses are shown as examples of various sensors 3.1, 3.2, 4.1, 4.2 and 5, which are connected to or communicate with the control unit 2. A power supply 6 and an actuator 7.1 and 7.2, respectively, for electrically modulating the optical effect of a lens 1A and 1B of the glasses to correct a refractive error, are also shown in a 120772P1423PC 14 / 20 Rodenstock GmbH

[0105] P2320 PCT

[0106] The development of presbyopia and / or ametropia, in particular hyperopia, myopia and / or astigmatism, is indicated.

[0107] Fig. 2 shows a method for controlling the adaptive corrective glasses 1 according to an embodiment of the present invention.

[0108] After being switched on (Fig. 2: step S10), for example by pressing control 2, sensors 3.1, 3.2, 4.1, 4.2 and 5 determine, in step S20, for example, eye, eyelid and / or pupil positions and / or movements and / or pupil sizes, gaze directions and / or eye focus and / or changes thereto and / or head positions and / or movements. Additionally or alternatively, they can detect the environment and / or changes in the environment.

[0109] In step S30, the controller 2 determines, based on sensor signals from one or more of the sensors 3.1, 3.2, 4.1, 4.2, and 5, whether a wearer of the glasses 1 is in a steady state (S30: "Y") or whether a non-steady state or no steady state exists (S30: "N"). By way of example, the controller 2 can determine that a steady state exists if it is determined that the wearer has maintained a sufficiently constant gaze on a specific area of ​​the environment for at least a predetermined time.

[0110] If the controller 2 determines that a steady state exists (S30: "Y"), it switches to a first operating mode. In this mode, in step S40, the controller 2, based on sensor signals from one or more of the sensors 3.1, 3.2, 4.1, 4.2, and 5, commands a change to at least one optical effect of the spectacles to correct a refractive error, specifically presbyopia and / or ametropia, in particular hyperopia, myopia, and / or astigmatism. By way of example, the controller 2 can, for instance, adapt the refractive power of the spectacle lenses 1A, 1B to the area of ​​focus that the wearer is fixating on, using the actuators 7.1, 7.2. 120772P1423PC 15 / 20 Rodenstock GmbH

[0111] P2320 PCT

[0112] Otherwise (S30: “N”), the system switches to a second operating mode in which control 2 does not command any change to at least one optical effect of the glasses with the same sensor signals.

[0113] If the wearer now shifts their gaze from a previously fixed area, for example a nearby object, to a different area, for example a distant object, no change in the optical effect of the glasses is commanded during this change of gaze or non-stationary state in which the wearer changes the viewing distance. Only when it is determined that the wearer is again fixating on an area for a sufficiently constant period of time does the control unit 2 adapt the refractive power of the lenses 1A, 1B to this area that the wearer is fixating on.

[0114] In the present disclosure, “an X indicates” implies 1This is generally not an exhaustive list, but rather a shorthand for "has at least one X" and also includes "has two or more X" as well as "has Y in addition to X". Although the preceding description provided examples, it should be noted that numerous variations are possible.

[0115] As explained above, in the second operating mode, or when the wearer of the glasses is in a non-steady-state condition, adaptation of the glasses 1 is suppressed. Alternatively, in the second operating mode or when the wearer is in a non-steady-state condition, a reduced and / or delayed adaptation can occur, so that when the new steady-state condition is reached, only a smaller (residual) adaptation is required, and the wearer is only minimally disturbed by the adaptation during the non-steady-state condition or gaze shift. A corresponding optional step S45 is indicated in Fig. 2. Additionally or alternatively, adaptation can also be delayed by switching to the first operating mode only after a predetermined time and then (only) in this mode commanding the change. 120772P1423PC 16 / 20 Rodenstock GmbH

Rather, the preceding description provides the skilled person with a guideline for implementing at least one exemplary embodiment, whereby various modifications, particularly with regard to the function and arrangement of the described components, can be made without departing from the scope of protection as defined by the claims and these equivalent combinations of features.
