Actuating a contact lens using millimeter electromagnetic waves

The present disclosure describes systems and techniques directed to detecting a user's gaze and using millimeter electromagnetic waves to actuate a focus system of a contact lens worn by the user. The described systems and techniques include a contact lens (108) having a focus system (222) and contact lens circuitry (226) that includes transceiver circuitry (228), logic circuitry (230), and memory circuitry (232). The memory circuitry (232) stores instructions of a focus manager application (234) that, when executed by the logic circuitry (230), directs the contact lens (108) to actuate the focus system (222) in response to receiving a signal (110) having a millimeter wave (114).

BACKGROUND

Contact lenses are a common remedy for a user experiencing a vision impairment such as myopia (near-sightedness) and presbyopia (far-sightedness). In general, a contact lens refracts light corresponding to an image through the contact lens such that a location of a focal point of the light lies on the retina of an eye. An accurate focal point location brings the image into focus and remedies the vision impairment. The contact lens can do so through a curvature, a thickness, or a material of the contact lens.

Today, “smart” contact lens technology is advancing to introduce into contact lenses features that include sensors for detecting glucose levels in a user's eye, imagers for capturing images and mechanisms for dynamically changing optical properties that impact focal points. Example mechanisms that can be used to dynamically change the optical properties of a smart contact lens include polymer gels having refractive indexes that change with electrical stimulation or films that can expand or contract with electrical stimulation to change a shape or thickness of a smart contact lens.

Current techniques for actuating mechanisms that dynamically change the optical properties of a smart contact lens, however, present several challenges. For example, techniques based on light-based actuation (e.g., light received into a photo-diode) may inadvertently actuate the mechanism if the user is gazing at a bright light, such as a headlight of an automobile. As another example, techniques relying on the user blinking or squinting (e.g., causing a sensed change in a capacitive field) may be inconsistent. Furthermore, current techniques may be independent from a direction of the user's gaze, resulting in the focal point being inaccurate to focus light reflected from objects in the direction of the gaze.

SUMMARY

The present disclosure describes systems and techniques directed to using signals having millimeter waves to actuate a focus system of a contact lens worn by the user. The described systems and techniques include a contact lens having a focus system and contact lens circuitry that includes transceiver circuitry, logic circuitry, and memory circuitry. The memory circuitry stores instructions of a focus manager application that, when executed by the logic circuitry, directs the contact lens to actuate the focus system in response to receiving a signal having millimeter waves.

In some aspects, a contact lens is described. The contact lens includes a focus system, an antenna, and circuitry. The circuitry includes transceiver circuitry, logic circuitry, and memory circuitry. The memory circuitry stores instructions of a focus manager application that, when executed by the logic circuitry, directs the contact lens to receive, through the antenna and transceiver circuitry and from a user equipment (UE), a signal including or consisting of electromagnetic waves that are within a spectrum that corresponds to a millimeter-wave spectrum. The focus manager application also directs the contact lens to determine, in response to receiving the signal, to change a focal length of the contact lens and actuate the focus system to change the focal length of the contact lens.

In some other aspects, a UE is described. The UE includes a focus assistant manager application that, when executed by a processor of the user equipment, directs the user equipment to present an image through a display. The focus assistant manager application also directs the UE to transmit a signal to a contact lens, where the signal includes or consists of electromagnetic waves within a millimeter-wave spectrum. The focus assistant manager application also directs to UE to transmit the signal to the contact lens, directing the contact lens to actuate a focus system of the contact lens to change a focal length of the contact lens.

The details of one or more implementations are set forth in the accompanying drawings and the following description. Other features and advantages will be apparent from the description and drawings, and from the claims. This summary is provided to introduce subject matter that is further described in the Detailed Description and Drawings. Accordingly, a reader should not consider the summary to describe essential features nor limit the scope of the claimed subject matter.

DETAILED DESCRIPTION

The present disclosure describes systems and techniques directed to detecting a user's gaze and using signals having millimeter waves to actuate a focus system of a contact lens worn by the user. The described systems and techniques include a contact lens having a focus system and contact lens circuitry that includes transceiver circuitry, logic circuitry, and memory circuitry. The memory circuitry stores instructions of a focus manager application that, when executed by the logic circuitry, directs the contact lens to actuate the focus system in response to receiving a signal having millimeter waves.

The described systems and techniques include millimeter-wave compatible wireless-communication hardware in the user equipment and the contact lens. The contact lens includes a focus system and a focus manager application, while the user equipment includes a focus assistant manager application that is complementary to the focus manager application.

The described systems and techniques have multiple advantages over other systems and techniques that use electromagnetic waves other than millimeter waves. As a first example, the described systems and techniques use wireless-communication hardware that has recently become available in UEs (e.g., radar systems and/or Fifth Generation New Radio (5G NR) transceivers), eliminating the need for additional wireless-communication hardware dedicated to the described techniques. As a second example, the described systems and techniques may beamform millimeter waves in a desired direction and to a desired attenuation distance (e.g., a viewing direction and distance between the UE and the contact lens). And, as a third example, the described systems and techniques using the millimeter waves reduce the possibility of non-intentional actuation of the contact lens (e.g., accidental light-based actuation through a photo diode in the contact lens).

While features and concepts of the described systems and techniques can be implemented in any number of different environments, systems, devices, and/or various configurations, aspects are described in the context of the following example devices, systems, and configurations.

Operating Environment

FIG.1illustrates an example operating environment100, which includes a user equipment (UE)102presenting an image104to a user106. The user106is wearing a contact lens108on their eye. The contact lens108is a “smart” contact lens, equipped with a focus system to correct vision conditions that may be experienced by the user106, including presbyopia and/or myopia. The user equipment102inFIG.1is implemented as a smartphone but may be implemented as any suitable computing device with display capabilities, such as a tablet, a television, a laptop computer, a home automation system display, or an Internet-of-Things (IoT) device.

Within the operating environment100, the UE102determines to transmit a signal110to the contact lens108to actuate a focus system of the contact lens108. In some instances, the UE102may determine to transmit the signal110in response to determining that the user106is gazing at the image104(e.g., gaze-direction112). In other instances, the UE102may determine to transmit the signal110in response to determining that the image104is a type of image that the user106may desire to view (e.g., the image104may be presented through viewer application that is a magnifier application, an e-reader application).

The signal110contains electromagnetic waves within a spectrum corresponding to the millimeter-wave spectrum. The millimeter-wave spectrum can range from 30 gigahertz (GHz) to 300 GHz. Electromagnetic waves within the millimeter-wave spectrum (e.g., mmWave114), can range from 10 millimeters (mm) in length down to 1 mm in length. In response to receiving the signal110, the contact lens108actuates the focus system to change a focal point of the image104within the eye of the user106.

The UE102and the contact lens108may perform complementary techniques to optimize viewability of the image104for the user106. As an example, the UE102may account for signal-receiving capabilities of the contact lens108to alter a transmission strength of the signal110or shape the signal110through beamforming to transmit the signal110a direction and attenuate the signal110within a range of acceptable viewing distances. As another example, the UE102may change a magnification level, a resolution level, or a brightness level of its display based on eyesight capabilities of the user106wearing the contact lens108. And, as yet another example, the contact lens108may account for display capabilities of the UE102to actuate or alter the focus system of the contact lens108.

Example Systems

FIG.2illustrates an example details200of user equipment and an example contact lens in accordance with one or more aspects. The user equipment may be the UE102ofFIG.1, while the contact lens may be the contact lens108ofFIG.1.

The UE102includes a gaze-detection system202that can aid in determining that the user106is gazing at the UE102. The gaze-detection system202may include elements such as an accelerometer and/or gyroscope to detect motion of the UE102(e.g., the user may be picking up UE102and gazing at the UE102), a near-field communication (NFC) device or proximity sensor to detect a presence of the user (e.g., the user may be near the UE102gazing at the UE102), or an image-capture sensor such as charge-couple device (CCD) or complementary metal-oxide semiconductor (CMOS) image sensor (e.g., facial recognition may indicate that the user is gazing at the UE102). In some instances, the gaze-detection system202may include infrared (IR) sensors that detect the presence of a user by detecting body heat.

The user equipment102also includes a radar system204for transmitting and receiving electromagnetic waves within the millimeter-wave spectrum. The radar system204may include multiple elements, including antennas, transceiver circuitry, processing circuitry, and beamforming circuitry. The beamforming circuitry may form beams that are steered or un-steered, wide or narrow, or shaped (e.g., as a hemisphere, cube, fan, cone, or cylinder). The elements of the radar system204may, in some instances, be fabricated on a single integrated circuit (IC) component

The radar system204may substitute or augment portions of the gaze-detection system202. For example, the radar system204may receive a signal (e.g., a signal other than the signal110ofFIG.1) from the contact lens108, indicating that the user106is gazing at the UE102. And, as yet another example, the radar system204may use gesture-recognition techniques to distinguish different orientations or gaze directions of the user106. Such gesture-recognition techniques may include scattering, in a pulsing fashion, a radar field on a target (e.g., the face of the user106), receiving reflections of the radar field from the target, and processing the received radar field to determine a gesture (e.g., gaze direction of the user106).

The UE102also includes a display206for displaying an image (e.g., the image104). Examples of the display206include a light-emitting diode (LED) display, an organic light-emitting diode (OLED) display, and a liquid crystal (LCD) display. The display206may be capable of performing zooming and/or magnification operations.

The UE102also includes a processor208and computer-readable storage media210(CRM210). The processor208may be a single-core processor or a multiple-core processor composed of a variety of materials, such as silicon, polysilicon, high-K dielectric, copper, and so on. The computer-readable storage media described herein excludes propagating signals. CRM210may include any suitable memory or storage device such as random-access memory (RAM), static RAM (SRAM), dynamic RAM (DRAM), non-volatile RAM (NVRAM), read-only memory (ROM), or Flash memory.

CRM210stores applications having executable code, including one or more viewer application(s)212(e.g., a media player application, a magnification-reader application, an e-reader application) and a focus assistant manager application214. The focus assistant manager application214includes sub-modules of code (e.g., gaze-detection module216, radar module218, display module220) that, when executed by the processor208, direct the UE102to perform operations described herein.

The CRM210may also store parameters, used by the focus assistant manager application214, to optimize a viewing of the image104by the user106. As a first example, the CRM210may store parameters relevant to signal-receiving capabilities of the contact lens108, such as a received signal strength indicator (RSSI) threshold (e.g., decibels (dB)), an accepted frequency range within the millimeter-wave spectrum, an expected beam diameter, and so on. In some instances, such parameters may be downloaded to the CRM210from a cloud-based content provider that is associated with the contact lens108. In other instances, such parameters may be available to the CRM210through millimeter-wave signals exchanging data (e.g., data packets, data frames) between the UE102and the contact lens108. Knowing the signal-receiving capabilities of the contact lens108, the UE102(e.g., the processor208executing code of focus assistant manager application214and the radar module218) may alter a transmission strength of the signal110or shape the signal110through beamforming, attenuating signal110within a range of viewing distances that are applicable to a viewing situation (e.g., if the UE102were a smartphone having a small display, it would not transmit the signal110a thousand meters; conversely, if the UE102were a television having a wide display, it would not transmit the signal110less than 1 meter). Such viewing distances may be, for example, between 0.0 and 1.0 meters, 0.5 meters and 1.5 meters, 1.0 meters and 3.0 meters, and so on.

As a second example, the CRM210may store parameters relevant to eyesight capabilities of the user106wearing the contact lens108(e.g., eyesight prescription information, a medical condition such as glaucoma, light sensitivity of the user). In some instances, such parameters may be downloaded to the CRM210from a medical service provider that is associated with the user106. In other instances, such parameters may be available to the CRM210through millimeter-wave signals exchanging data (e.g., data packets, data frames) between the UE102and the contact lens108. Knowing eyesight capabilities of the user106wearing the contact lens108, the UE102(e.g., the processor208executing the code of the display module220) may change a magnification level, a resolution level, or a brightness level of the display206.

The contact lens108includes a focus system222. The focus system222may use one of a variety of mechanisms to change a focal point of an image passing through the contact lens108and into an eye of the user106. As a first example mechanism, the focus system222may include a saline-filled bladder made from polymer films that change structure (e.g., expand, contract) when an electrical stimulus (e.g., an electrooculographical potential) is applied to the polymer films. As a second example mechanism, the focus system222may include a polymer gel filled bladder, where a refractive index of the polymer gel changes when an electrical or magnetic stimulus is applied to the polymer gel.

The contact lens108includes a mmWave antenna224and contact lens circuitry226. The contact lens circuitry226includes multiple elements, including transceiver circuitry228, logic circuitry230, and memory circuitry232. In some instances, the contact lens circuitry226may be passive, collecting energy from electromagnetic waves to generate power to operate features of the contact lens108. In other instances, the contact lens circuitry226may be active, relying on a battery-storage device that may be included on the smart contact lens. In some aspects, the mmWave antenna224and the transceiver circuitry228may be a portion of a radio frequency identification (RFID) system that is integrated into the contact lens108.

The logic circuitry230may be based on a single-core processor or a multiple-core processor and composed of a variety of materials, such as silicon, polysilicon, high-K dielectric, copper, and so on. The memory circuitry232may be a computer-readable media (CRM) and based on memory cells of a suitable memory device such as random-access memory (RAM), static RAM (SRAM), dynamic RAM (DRAM), non-volatile RAM (NVRAM), read-only memory (ROM), or Flash memory device. The memory circuitry232may store executable code of a focus manager application234that, when executed by the logic circuitry230, directs the contact lens108to perform operations described herein.

The memory circuitry232may also store parameters, used by the logic circuitry230executing the focus manager application234, to optimize a viewing of the image104by the user106. As a first example, the memory circuitry232may store parameters that the contact lens108can share with the UE102to indicate signal-receiving capabilities of the contact lens108, such as a received signal strength indicator (RSSI) threshold (e.g., decibels (dB)), a supported frequency range within the millimeter-wave spectrum, a supported beam diameter, and so on. In some instances, such parameters may be programmed into the memory circuitry232during manufacture of the contact lens108.

The memory circuitry232may store parameters indicating capabilities of the UE102displaying the image104. Such parameters may include a model or configuration of the UE102, an available signal-transmission power in decibels (dB), an estimated distance between the UE102and the contact lens108(e.g., determined by the radar system204of the UE102), qualities of the display206(e.g., a resolution, an illumination power), available formats of the image104, and so on. Data frames or data packets carried by the electromagnetic wave(s)114of the signal110may include the parameters.

The memory circuitry232may also store parameters indicating eyesight capabilities of the user106wearing the contact lens108(e.g., eyesight prescription information, a medical condition such as glaucoma, light sensitivity of the user). In some instances, such parameters may be downloaded to the memory circuitry from a medical service provider that is associated with the user106.

In some instances, UE102may actuate the focus system222by applying an electrical stimulus (either actively sourced from a battery or passively sourced from received electromagnetic waves) to the focus system222. Actuating the focus system222may include actuating the focus system222to one of multiple, available degrees of actuation, where each degree of actuation corresponds to a different location of a focal point of the image104within an eye of the user106wearing the contact lens108. Furthermore, actuating the focus system222may be based on the parameters indicating eyesight capabilities of the user106wearing the contact lens108and/or the parameters indicating capabilities of the UE102presenting the image104.

In general, and further to the descriptions above, the UE102and/or the contact lens108may provide the user106controls to make an election as to both if and when systems, programs, or features described herein to enable and/or disable collection of user information associated with the user106(e.g., information about a vision or medical condition of the user106, focal settings and/or use of the contact lens108, content of images (e.g., the image104) being viewed by the user). Such controls further enabling and/or disabling communication with a server. In addition, certain data may be treated in one or more ways before it is stored or used so that personally identifiable information is removed. Thus, the user106is provided with control over what information is collected about the user106, how that information is used, and what information is provided to the user106.

FIG.3illustrates example details300of actuating a focus system of a contact lens in accordance with one or more aspects. The contact lens may be the contact lens108ofFIG.1using the focus system222ofFIG.2. An example embodiment of the focus system222, as illustrated inFIG.3, includes a bladder filled with a polymer gel.FIG.3illustrates the focus system222being actuated to alleviate a presbyopia condition (e.g., far-sightedness) being experienced by the user106ofFIG.1.

As illustrated, an eye302(e.g., of the user106) is receiving light waves304of an image (e.g., the image104) being presented by a user equipment (e.g., the UE102). Optical properties of an optical network, including the contact lens108, the focus system222(e.g., the bladder having a polymer gel in a first state having a first refractive index306), and a cornea308of the eye302, focus the light waves304at focal point310. The focal point310, at a location “behind” the retina of the eye302, corresponds to the presbyopia condition.

As illustrated byFIG.3, a signal (e.g., the signal110including mmWave(s)114) is received by the contact lens108(e.g., the mmWave antenna224, the transceiver circuitry228). In response, the contact lens108(e.g., the logic circuitry230executing code of the focus manager application234) actuates the focus system222(e.g., electrically stimulates the polymer gel to induce a second state having a second refractive index312). The optical properties of the optical network, including the contact lens108, focus the light waves304at focal point314. The focal point314changes to a location that is proximate the retina of the eye302and corresponds to an in-focus condition.

FIG.4illustrates example details400of actuating a focus system of a contact lens in accordance with one or more aspects. The contact lens may be the contact lens108ofFIG.1using the focus system222ofFIG.2. An example embodiment of the focus system222, as illustrated inFIG.4, includes a bladder formed from a polymer filmFIG.4illustrates the focus system222being actuated to alleviate a myopia condition (e.g., near-sightedness) being experienced by the user106ofFIG.1.

As illustrated, the eye302is receiving the light waves304. Optical properties of an optical network, including the contact lens108, the focus system222(e.g., the bladder in a first state having a first dimension402), and a cornea308of the eye302, focus the light waves304at focal point404. The focal point404, at a location “in front of” the retina of the eye, corresponds to the myopia condition.

As illustrated byFIG.4, a signal (e.g., the signal110including mmWave(s)114) is received by the contact lens108(e.g., the mmWave antenna224, the transceiver circuitry228). In response, the contact lens108(e.g., the logic circuitry230executing code of the focus manager application234) actuates the focus system222(e.g., electrically stimulates the polymer film of the bladder to induce a second state having a second dimension406). The optical properties of the optical network, including the contact lens108, focuses the light waves304at focal point314. The focal point314changes to a location that is proximate the retina of the eye302and corresponds to an in-focus condition.

Example Methods

FIG.5illustrates an example method500performed by a contact lens having a focus system in accordance with one or more aspects. The contact lens (e.g., the contact lens108ofFIG.1, using elements ofFIGS.2-4) is directed to perform the method500by logic (e.g., the logic circuitry230) executing code of a focus manager application (e.g., the focus manager application234). Operations of the method500are described in a series of blocks502-506and are not limited to the order or sequence as described below.

At block502, the contact lens108receives, from a user equipment (e.g., the UE102), a signal (e.g., the signal110) including electromagnetic waves (e.g., the mmWave(s)114) that are within a spectrum corresponding to millimeter-wave spectrum.

At block504, and in response to receiving the signal110including the electromagnetic waves, the contact lens108determines to change a focal length of the contact lens108.

At block506, and in response to determining to change the focal length of the contact lens, the contact lens108actuates a focus system (e.g., the focus system222) of the contact lens108. Actuating the focus system222changes the focal length of the contact lens. Changing the focal length of the contact lens108may change a location of a focal point of the image104within an eye (e.g., the eye302) of a user (e.g., the user106) wearing the contact lens108.

In some instances, the method500may change the location of the focal point of the image104in the eye302of the user106to overcome a presbyopia condition of the user106. In other instances, the method500may change the location of the focal point of the image104in the eye302of the user106to overcome a presbyopia condition.

In some instances of method500, the signal110including the electromagnetic wave(s)114may be a beamformed signal. The signal110may carry data that indicates, to the contact lens108, an estimated distance between the UE102and the contact lens108and/or qualities of a display (e.g., the display206) of the UE102. In such instances, actuating the focus system222at block506may include actuating the focus system222to one of multiple, available degrees of actuation based on the estimated distance. The signal110may also carry data that includes an identifier associated with the UE102such that the contact lens108may determine that the signal110originates from the UE102(e.g., the contact lens108may not determine to change the focal length of the contact lens if such an identifier is not included).

FIG.6illustrates an example method600performed by a user equipment in accordance with one or more aspects. The user equipment (e.g., the UE102ofFIG.1, using elements ofFIGS.2-4) is directed to perform the method600by a processor (e.g., the processor208) executing code of a focus assistant manager application (e.g., the focus assistant manager application214). Operations of the method600are described in a series of blocks602-606and are not limited to the order or sequence as described below.

At block602, the UE102presents, through a display (e.g., the display206), an image (e.g., the image104).

At block604, the UE102(e.g., the processor208executing the code of the focus assistant manager application214) determines to transmit a signal (e.g., the signal110) to a contact lens (e.g., the contact lens108). The signal110includes electromagnetic waves (e.g., mmWave114) within a spectrum corresponding to a millimeter-wave spectrum.

At block606, the UE102transmits the signal to the contact lens108. Transmitting the signal110to the contact lens108causes the contact lens108to actuate a focus system (e.g., the focus system222) that changes a focal length of the contact lens108. Changing the focal length of the contact lens108may change a location of a focal point of the image104within an eye (e.g., the eye302) of a user (e.g., the user106) wearing the contact lens108.

In some instances of method600, determining to transmit the signal110may be in response to determining that the image104is associated to a type of viewer application (e.g., the viewer application212) that is executing on the UE120. For example, the viewer application212may be a type of viewer application that is a magnifier application or an e-reader application.

In other instances of method600, determining to transmit the signal110may be in response to determining that the user106is gazing at the image104. Determining that the user106is gazing at the image104may include recognizing the user106through facial-recognition, recognizing a gesture using a radar reflection, receiving another signal from the contact lens108, or detecting a change in an orientation of the UE102.

The method600may also include additional operations. As an example, UE102may change a magnification level, a resolution level, or a brightness level of the display206. In some instances, changing the magnification level, the resolution level, or the brightness level may be based on known eyesight capabilities of the user106(e.g., the eyesight capabilities of the user106may be stored in the CRM210and known by the UE120).

Variations

There are many variations and permutations of the above-described systems and techniques. As a first example, an as opposed to the contact lens108, the techniques can apply to a wearable optics system that includes a focus system (e.g., the focus system222). Such a wearable optics system may be a heads-up display, augmented-reality goggles, reading glasses, and so on. As a second example, and as opposed to receiving a signal from the UE102, the contact lens108may receive a reflection of a millimeter-wave signal that the contact lens108transmits (e.g., the contact lens108may be equipped with a radar system to detect an object and actuate the focus system222).
