Systems, apparatus, and methods for using a wearable device to monitor operator alertness

Abstract

A computer system and method is adapted for determining an alertness of a wearer of a computerized wearable device having one or more sensors by receiving a signal from the sensors and determining a baseline heart rate of the wearer. The system monitors the wearer for an elevated heart rate and/or transmits a stimulus to the wearer to produce an elevated heart rate. In response to the elevated heart rate, the system compares the wearer's current heart rate to the wearer's baseline heart rate to determine the wearer's current alertness by calculating the length of time it takes the wearer's current heart rate to return to the baseline heart rate. The system notifies the wearer of the wearer's current alertness by generating an alert such as sending a notification to the wearer's computing device. The system may also generate an alert from a vehicle driven by the wearer.

Description

BACKGROUND

Individuals may become drowsy while driving or operating a machine because of monotonous driving conditions, lack of sleep, or due to a medical condition. When individuals drive or operate machinery while drowsy, accidents are prone to happen. Other accidents may also occur when an individual becomes distracted while driving or operating machinery. Accordingly, there is a need for improved systems and methods for monitoring the alertness of an individual, especially when the individual is driving or operating machinery. Various embodiments of the present systems and methods recognize and address the foregoing considerations, and others, of prior art systems and methods.

DETAILED DESCRIPTION OF SOME EMBODIMENTS

Various embodiments will now be described more fully hereinafter with reference to the accompanying drawings. It should be understood that the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout.

Overview

A wearable alertness monitoring system, in various embodiments, may, for example, be embodied in any suitable wearable device configured to monitor the alertness of a wearer. The system may, for example, be embodied as a pair of eyewear, as contact lenses, as a wristwatch, as a suitable piece of clothing (e.g., such as a suitable shirt, pair of pants, undergarment, compression sleeve, etc.), as footwear, as a hat, as a helmet, as an orthopedic cast, or any other suitable wearable item. In a particular example, a wearable alertness monitoring system embodied as a pair of eyewear may enable the system to access one or more (e.g., all five) of a wearer's senses (e.g., touch, sight, sound, smell, and taste) based at least in part on a proximity of the eyewear to the wearer's sensory systems (e.g., eyes, mouth, ears, nose) when worn by the wearer. In other embodiments, a wearable alertness monitoring system embodied as a helmet may enable the system to determine impact, acceleration, posture, and other physiological attributes of the wearer.

In various embodiments, the system comprises one or more sensors configured to determine one or more physiological attributes of the wearer. The one or more sensors may be coupled to the wearable device in any suitable way. For instance, the one or more sensors may be embedded into the wearable device, coupled to the wearable device, and/or operatively coupled to the wearable device. The one or more sensors may include, for example, one or more heart rate monitors, one or more electrocardiogram (EKG) sensors, one or more pedometers, one or more gyroscopes, one or more geomagnetic sensors, one or more thermometers, one or more front-facing cameras, one or more eye-facing cameras, one or more microphones, one or more accelerometers, one or more blood pressure sensors, one or more pulse oximeters, one or more near-field communication sensors, one or more bone scanners, one or more infrared LED/photodiode sensor combinations, one or more photodiode sensors, one or more magnetometers, or any other suitable one or more sensors. In particular embodiments, the system is configured to gather data about the wearer, for example, using the one or more sensors (e.g., such as temperature, balance, heart rate, activity, activity levels, alertness, food eaten, medications taken, steps taken, head position, body movements, facial muscle movements, trauma, etc.).

In some embodiments, one or more body position sensors may be physically or wirelessly coupled to the wearable device and adapted to assess the relative positions of two or more of the wearer's body parts over time in order to determine whether the wearer's head position is desirable or undesirable (e.g., whether the wearer's head has slumped forward). For example, the wearable device may include a magnetometer that is adapted to sense the relative positions of a first magnet that a wearer is wearing adjacent the wearer's forehead (e.g., as an adhesive attachment or embedded within an article of clothing) and a second magnet that the wearer is wearing adjacent the wearer's chest (e.g., as an adhesive attachment or embedded within an article of clothing). The system may then use data obtained from the magnetometer regarding the relative positions of the magnets to determine whether the wearer's head is slumping forward. In response to determining that the wearer's head is slumping forward, the system may send an alert to the wearer indicating that they should resume a correct head position.

In various embodiments, the sensors determine the alertness of the wearer by monitoring the wearer's heart rate, pulse, orientation, acceleration, geomagnetic field, and images from the one or more front facing cameras and/or one or more eye-facing cameras. The system may measure the wearer's baseline levels based on these characteristics to determine the wearer's normal alertness. The system may measure the wearer's baseline once to create a static baseline, or intermittently to create a dynamic baseline. After determining the wearer's normal alertness based on the baseline levels from the sensors, the system may receive at least one signal from the one or more sensors. The system may use the at least one signal received from the one or more sensors to determine the wearer's current alertness. The system may then compare the wearer's current alertness to the wearer's baseline (e.g., normal) alertness. If the wearer's current alertness deviates from the normal alertness of the wearer, the system may notify the wearer of the deviation. In some embodiments, the system may notify a third party of the deviation. In various embodiments, the system may notify the wearer via the wearable device or through a notification sent to a mobile device associated with the wearer. In some embodiments, the system may also provide suggestions to the wearer on how to change the wearer's current alertness to conform to the wearer's normal alertness. The system, in particular embodiments, may also provide suggestions to the wearer on the cause of the wearer's current alertness. For instance, where the wearer's current alertness includes a lowered head, closed eyes, and slumped shoulders (as determined by additional sensors placed on the wearer's shoulders) and the wearer's normal alertness is sitting up straight with shoulders back, the system may determine that the wearer is sleeping. After determining that the wearer is sleeping, the system may notify the wearer to wake up or to correct their current alertness to their normal alertness. The system may also suggest the cause of the wearer's deviation in alertness (e.g., fatigue).

In various embodiments, while the system is using one or more sensors (e.g., eyewear based sensors) to assess the alertness of the wearer, the system may also (e.g., at least substantially simultaneously) capture one or more images of the wearer or the wearer's surroundings (e.g., using a camera, such as a forward-facing camera associated with eyewear worn by the wearer) that may be used in determining the user's activity or physiological state.

Exemplary Technical Platforms

As will be appreciated by one skilled in the relevant field, the present systems and methods may be, for example, embodied as a computer system, a method, or a computer program product. Accordingly, various embodiments may be entirely hardware or a combination of hardware and software. Furthermore, particular embodiments may take the form of a computer program product stored on a computer-readable storage medium having computer-readable instructions (e.g., software) embodied in the storage medium. Various embodiments may also take the form of web-implemented computer software. Any suitable computer-readable storage medium may be utilized including, for example, hard disks, compact disks, DVDs, optical storage devices, and/or magnetic storage devices.

Various embodiments are described below with reference to block diagram and flowchart illustrations of methods, apparatuses, (e.g., systems), and computer program products. It should be understood that each block of the block diagrams and flowchart illustrations, and combinations of blocks in the block diagrams and flowchart illustrations, respectively, can be implemented by a computer executing computer program instructions. These computer program instructions may be loaded onto a general purpose computer, a special purpose computer, or other programmable data processing apparatus that can direct a computer or other programmable data processing apparatus to function in a particular manner such that the instructions stored in the computer-readable memory produce an article of manufacture that is configured for implementing the functions specified in the flowchart block or blocks.

The computer instructions may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on a user's computer and partly on a remote computer, or entirely on the remote computer or server.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner such that the instructions stored in the computer-readable memory produce an article of manufacture that is configured for implementing the function specified in the flowchart block or blocks. The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer-implemented process (e.g., method) such that the instructions that execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart block or blocks.

The communication link between the One or More Remote Computing Devices 154 and the Mental State Monitoring Server 120 may be, for example, implemented via a Local Area Network (LAN) or via the Internet.

FIG. 2 illustrates a diagrammatic representation of the architecture for the Alertness Monitoring Server 120 that may be used within the Alertness Monitoring System 100. It should be understood that the computer architecture shown in FIG. 2 may also represent the computer architecture for any one of the One or More Remote Computing Devices 154, the one or more Third Party Servers 50, and the one or more Health Monitoring Devices 156 shown in FIG. 1. In particular embodiments, the Alertness Monitoring Server 120 may be suitable for use as a computer within the context of the Alertness Monitoring System 100 that is configured for determining an alertness of a wearer of a computerized wearable device using signals received from sensors coupled to the computerized wearable device.

In particular embodiments, the Alertness Monitoring Server 120 may be connected (e.g., networked) to other computing devices in a LAN, an intranet, an extranet, and/or the Internet as shown in FIG. 1. As noted above, the Alertness Monitoring Server 120 may operate in the capacity of a server or a client computing device in a client-server network environment, or as a peer computing device in a peer-to-peer (or distributed) network environment. The Alertness Monitoring Server 120 may be a desktop personal computing device (PC), a tablet PC, a set-top box (STB), a Personal Digital Assistant (PDA), a cellular telephone, a web appliance, a network router, a switch or bridge, or any other computing device capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that computing device. Further, while only a single computing device is illustrated, the term “computing device” shall also be interpreted to include any collection of computing devices that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein.

An exemplary Alertness Monitoring Server 120 includes a processing device 202, a main memory 204 (e.g., read-only memory (ROM), flash memory, dynamic random access memory (DRAM) such as synchronous DRAM (SDRAM) or Rambus DRAM (RDRAM), etc.), a static memory 206 (e.g., flash memory, static random access memory (SRAM), etc.), and a data storage device 218, which communicate with each other via a bus 232.

The processing device 202 represents one or more general-purpose or specific processing devices such as a microprocessor, a central processing unit (CPU), or the like. More particularly, the processing device 202 may be a complex instruction set computing (CISC) microprocessor, reduced instruction set computing (RISC) microprocessor, very long instruction word (VLIW) microprocessor, or processor implementing other instruction sets, or processors implementing a combination of instruction sets. The processing device 202 may also be one or more special-purpose processing devices such as an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a digital signal processor (DSP), network processor, or the like. The processing device 202 may be configured to execute processing logic 226 for performing various operations and steps discussed herein.

The Alertness Monitoring Server 120 may further include a network interface device 208. The Alertness Monitoring Server 120 may also include a video display unit 210 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)), an alpha-numeric input device 212 (e.g., a keyboard), a cursor control device 214 (e.g., a mouse), and a signal generation device 216 (e.g., a speaker).

The data storage device 218 may include a non-transitory computing device-accessible storage medium 230 (also known as a non-transitory computing device-readable storage medium, a non-transitory computing device-readable medium, or a non-transitory computer-readable medium) on which is stored one or more sets of instructions (e.g., the Alertness Monitoring Module 300) embodying any one or more of the methodologies or functions described herein. The one or more sets of instructions may also reside, completely or at least partially, within the main memory 204 and/or within the processing device 202 during execution thereof by the Alertness Monitoring Server 120—the main memory 204 and the processing device 202 also constituting computing device-accessible storage media. The one or more sets of instructions may further be transmitted or received over a network 115 via a network interface device 208.

While the computing device-accessible storage medium 230 is shown in an exemplary embodiment to be a single medium, the term “computing device-accessible storage medium” should be understood to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term “computing device-accessible storage medium” should also be understood to include any medium that is capable of storing, encoding, or carrying a set of instructions for execution by the computing device and that causes the computing device to include any one or more of the methodologies of the present invention. The term “computing device-accessible storage medium” should accordingly be understood to include, but not be limited to, solid-state memories, optical and magnetic media, etc.

Exemplary System Platform

As noted above, a system, according to various embodiments, is adapted to monitor the alertness of a wearer of a wearable device. Various aspects of the system's functionality may be executed by certain system modules, including the Alertness Monitoring Module 300. The Alertness Monitoring Module 300 is discussed in greater detail below.

Alertness Monitoring Module

FIG. 3 is a flow chart of operations performed by an exemplary Alertness Monitoring Module 300, which may, for example, run on the Alertness Monitoring Server 120, or any suitable computing device (such as the One or More Health Monitoring Devices 156 or other suitable mobile computing device). In particular embodiments, the Alertness Monitoring Module 300 may determine a wearer's normal alertness and current alertness to determine whether the wearer's current alertness deviates from the wearer's normal alertness.

The system begins, in various embodiments, at Step 305 by receiving at least one signal from one or more sensors of a computerized wearable device. In various embodiments, the one or more sensors are coupled to a computing device that is associated with (e.g., embedded within, attached to) the computerized wearable device or other health monitoring device. In particular embodiments, the computerized wearable device or other health monitoring device comprises at least one processor, computer memory, suitable wireless communications components (e.g., a Bluetooth chip), and a power supply for powering the health monitoring device and/or the various sensors. In various embodiments, the one or more sensors may be adapted to detect one or more characteristics of a wearer of the computerized wearable device, wherein the one or more characteristics of the wearer are associated with the wearer's alertness. In various embodiments, the sensors coupled to the computerized wearable device or other health monitoring device may include, for example, one or more of the following: a heart rate monitor, an electrocardiogram (EKG), a gyroscope, a geomagnetic sensor, a pedometer, a thermometer, a front-facing camera, an eye-facing camera, a microphone, an accelerometer, a magnetometer, a blood pressure sensor, a pulse oximeter, a skin conductance response sensor, a near-field communication sensor, an infrared LED/photodiode sensor combination, a magnetometer, an electrooculography sensor, or any other suitable sensor. In particular embodiments, the sensors coupled to the computerized wearable device comprise one or more of a heart rate monitor, a pulse oximeter, gyroscope, a forward facing camera, and an eye-facing camera.

Referring to FIG. 4, an exemplarily embodiment of a computerized wearable device in the form of eyewear, according to particular embodiments, illustrates that the one or more sensors may be physically coupled to eyewear 400 in any suitable way. For example, in various embodiments, the one or more sensors may be embedded into the eyewear 400. In some embodiments, the one or more sensors may be positioned along the frame 410 of the eyewear 400. In other embodiments, the one or more sensors may be positioned along the temples 412, 414 of the eyewear 400. In still other embodiments, the one or more sensors may be coupled to one or more of the lenses 418, 420 of the eyewear 400. As noted above, the one or more sensors may be coupled to a Bluetooth device that is configured to transmit the one or more signals to a handheld wireless device, and the step of receiving one or more signals from the one or more sensors (discussed below with reference to Step 320) further comprises receiving the one or more signals from the wireless handheld device (e.g., via the Internet, Wi-Fi, a cellular network, etc.). In particular embodiments, one or more of the one or more sensors may be detachable from the eyewear 400. For instance, if a wearer does not need a temperature sensor or other particular sensor, the sensor may be removed from the eyewear. In other embodiments, the one or more sensors may be detached from the eyewear to attach to other portions of the wearer's body. For example, in determining the level of alertness of the wearer, the gyroscope, accelerometer, or other suitable device may be attached to the wearer's back or shoulders and may be adapted to transmit data to the eyewear. The structure of the eyewear will be discussed further below.

Returning to FIG. 3, in particular embodiments, the at least one signal from the one or more sensors may include one or more signals that may be used to derive: (1) the wearer's heart rate, (2) the wearer's heart rhythm; (3) a distance traveled by the wearer; (4) the wearer's body temperature; (5) one or more images associated with the wearer or the wearer's environment; (6) one or more sounds associated with the wearer's body or the wearer's environment; (7) a speed traveled by the wearer; (8) the wearer's blood pressure; (9) the wearer's oxygen saturation level; (10) the wearer's brainwave activity; (11) the wearer's pupil size; (12) the wearer's perspiration level; (13) the wearer's respiratory rate; (14) the number and/or cadence of steps taken by the wearer; (15) the movement of one or more of the wearer's facial muscles; (16) one or more biochemical changes within the wearer's body (e.g., changes in hormone levels, releases of neurotransmitters); (17) changes in the one or more characteristics of the wearer's skin (e.g., skin paleness or clamminess); (18) one or more postures associated with the wearer; and/or (19) measuring the corneo-retinal standing potential that exists between the front and the back of the human eye, (20) any other suitable attribute of the wearer or the wearer's environment. For instance, the system may receive a signal from an eye-facing camera associated with the eyewear that the wearer is looking down at the same time that the system receives a signal from the front-facing camera that there is a road in front of the wearer.

In particular embodiments, the system may receive one or more of the above-referenced signals substantially automatically. In various embodiments, the system may receive one or more of the signals on a substantially periodic basis (e.g., by the second, by the minute, hourly, daily, etc.). For example, the system may receive one or more signals every thirty seconds throughout the day. In other embodiments, the system may receive one or more signals at least partially in response to receiving an indication from the wearer that the system should receive a signal. For instance, the wearer may speak a voice command to the wearable device requesting that the device receive a signal from the gyroscope to get the wearer's orientation. In various embodiments, the system may receive an indication from the wearer of when to have the system receive the signal. For example, the system may receive an indication from the wearer to have the system receive a signal from the gyroscope at 8:00 a.m. and at 2:00 p.m. on a particular day. In particular embodiments, the system may receive a request from the wearer to have a particular signal received from a particular sensor at the same time that the system receives a second particular signal from a second particular sensor. For example, when the system receives a signal that indicates that the wearer's pupil size has changed, the system may, at least partially in response to receiving the changed pupil size signal, also obtain an orientation of the wearer from the gyroscope associated with the eyewear.

In various embodiments, the system may receive one or more signals at least partially in response to receiving an indication from a third party that the system should receive a signal. For instance, the third party may remotely request that the wearable device receive a signal from the heart rate monitor. In some embodiments, the system may receive an indication from the third party of when to have the system receive the signal. For example, the system may receive an indication from the third party (e.g., the wearer's supervisor) to have the system receive a signal from the heart rate monitor every 15 minutes. In particular embodiments, the system may receive a request from the third party to have a particular signal received from a particular sensor at the same time that the system receives a second particular signal from a second particular sensor. For example, when the system receives a signal that indicates that the wearer's heart rate has increased, the system may, at least partially in response to receiving the increased heart rate signal, also obtain an image from the eye-facing camera associated with the eyewear, which may be analyzed by the system to determine why the wearer's heart rate increased.

In some embodiments, the system receives a signal of an image captured by the eyewear. In various embodiments, the system receives a plurality of images captured by the eyewear. In particular embodiments, the system receives the image from the front-facing camera. In some embodiments, the system receives the image substantially automatically from the front-facing camera. In other embodiments, the system may receive the image in response to receiving an indication from the wearer to capture the image. For example, the system may receive a voice command from the wearer to capture the image. In various embodiments, the system may store the captured image in local or remote memory. In some embodiments, the image captured by the eyewear may be a video.

In various embodiments, the system may receive only one signal from a single sensor associated with the eyewear. In other embodiments, the system may receive a signal from a plurality of the sensors associated with the eyewear. In yet other embodiments, the system may receive multiple signals from one or more of the sensors. In various embodiments, the system may be configured to receive a first signal from a first sensor at the same time that it receives a second signal from a second sensor. For example, the system may be configured to receive an image signal from an eye-facing camera associated with the eyewear at the same time that the system receives an orientation signal from the gyroscope associated with the eyewear. As a further example, the system may be configured to simultaneously receive a signal from both an eye-facing camera and a heart rate monitor associated with the eyewear.

At least partially in response to receiving the at least one signal, at Step 310, the system determines a baseline heart rate of the wearer of the computerized wearable device. In particular embodiments, the baseline heart rate of the wearer may be indicative of a normal heart rate of the wearer. In particular embodiments, the baseline heart rate may be a normal starting baseline heart rate of the wearer. For instance, the normal starting baseline heart rate of the wearer when the wearer wakes up may be a resting heart rate range from 60 to 100 beats per minute. In other embodiments, the baseline heart rate may be a desired baseline heart rate of the wearer. For instance, the baseline heart rate may be received from medical guidelines based on a desired baseline heart rate for a wearer of the same sex, height, weight, age, etc. In still other embodiments, the baseline heart rate may be a baseline level of an average person (e.g., not a baseline level based on measurements from the wearer).

In various embodiments, the system may determine the baseline heart rate from a single heart rate monitor. The system may, in some embodiments, determine the baseline heart rate multiple times (e.g., measure the baseline heart rate from the heart rate monitor three times) to create an average baseline heart rate. In various embodiments, the system may be configured to determine the baseline heart rate from the heart rate monitor at the same time that it determines one or more physiological baseline levels from a second sensor. For example, the system may be configured to receive a baseline heart rate at the same time that it receives a position measurement from the accelerometer. In addition, the system may also receive an oxygen saturation level from a pulse oximeter sensor to determine the wearer's blood oxygen level, which may be used in supplementing alertness measurements, balance measurements, and position measurements.

In various embodiments, the system may determine the baseline heart rate substantially automatically after the sensor generates the data. In particular embodiments, the system may determine the baseline heart rate only once to create a static baseline. In some embodiments, the system may determine the baseline heart rate periodically (e.g., by the second, by the minute, hourly, daily, etc.) to create a dynamic baseline. For example, the system may determine the wearer's heart rate every thirty seconds throughout the day to create a dynamic baseline for the wearer's heart rate. In other embodiments, the system may determine the baseline heart rate after receiving an indication from the wearer and/or a third party that the system should determine the one or more baseline levels.

In particular embodiments, the system may determine the baseline heart rate during a predefined time period. In various embodiments, the system may determine the baseline heart rate when a sensor detects movement and/or activities of the wearer (e.g., sitting, lying down, standing, driving a vehicle, flying in an airplane, walking, running, lifting, exercising, etc.). For example, the system may determine the baseline heart rate when the sensor detects that the wearer is driving a vehicle as determined by the speed at which the wearer is currently traveling.

In particular embodiments, the system may store the baseline heart rate in associated memory. In various embodiments, the system may store the baseline heart rate substantially automatically after measuring the data. In other embodiments, the system may store the baseline heart rate after receiving manual input from the wearer and/or a third party requesting that the system store the baseline heart rate. In various embodiments, the system may store the baseline heart rate for a specified period of time. For instance, the system may store the baseline heart rate for a day, a month, a year, etc., in the Database 140. In some embodiments, the system may store the baseline heart rate on any suitable server or other device. In various embodiments, the system may store the baseline heart rate on the Alertness Monitoring Server 120. In particular embodiments, the system may store the baseline heart rate in an account associated with the wearer. In various embodiments, the system may store the baseline heart rate with a timestamp of when the one or more baseline levels were received.

Continuing at Step 315, the system transmits at least one stimulus from one or more stimulus transmitters to the wearer. In various embodiments, the at least one stimulus from the one or more stimulus transmitters may include: (1) a vibration; (2) a change in temperature; (3) a smell; (4) a light; (5) a sound; (6) a shock, (7) or any other suitable stimulus that causes a reaction in the wearer. In particular embodiments, the at least one stimulus is intended to produce a reaction in the wearer (e.g., physical reaction, emotional reaction, neurological reaction, etc.). For example, a particular stimulus may produce an emotional reaction in the wearer causing the wearer to become excited. In some embodiments, the one or more stimulus transmitters may be any suitable transmitter such as: (1) a vibration transmitter; (2) a temperature changing transmitter; (3) a smell transmitter; (4) a light transmitter; (5) a sound transmitter; and (6) a shock transmitter.

In particular embodiments, the one or more stimulus transmitters may be operatively coupled to a vehicle that the wearer drives and/or machinery that the wearer operates. For example, the one or more stimulus transmitters may be configured to generate one or more stimuli from one or more of the following vehicle systems: (1) in-cabin climate control; (2) audio system; (3) engine; (4) in-cabin lighting elements; and (5) brakes. By being operatively coupled to the one or more vehicle systems, the one or more transmitters may be configured to generate one or more stimuli such as: (1) turning up or down the volume on the vehicle's audio system; (2) disabling the driving functionality of the vehicle; (3) turning up or down the temperature on the vehicle's in-cabin climate control; (4) turning on or off the lights in the vehicle's cabin; (5) applying the brakes on the vehicle, (6) etc.

In particular embodiments, the one or more stimulus transmitters may be configured to transmit the at least one stimuli from one or more remote computing devices associated with the wearer and/or a third party. For example, the one or more stimulus transmitters may transmit the at least one stimuli from the wearer's cellphone by causing the cellphone to ring, vibrate, create a flashing light, and/or any other suitable alert. In various embodiments, the system is configured to transmit the one or more stimuli wirelessly (e.g., via a cellular network, Bluetooth, WI-FI, etc.).

At Step 320, the system determines a current heart rate of the wearer. In particular embodiments, the system determines the current heart rate of the wearer at least partially in response to the system transmitting at least one stimulus from the one or more stimulus transmitters to the wearer. In some embodiments, the system determines the current heart rate of the wearer prior to the system transmitting at least one stimulus from the one or more stimulus transmitters to the wearer. In some of these embodiments, the system may also determine the current heart rate of the wearer after the system transmits the at least one stimulus to the wearer. In particular embodiments, the system may determine the current heart rate of the wearer after detecting a change in the wearer's current heart rate. In particular embodiments, the system may determine the current heart rate after receiving an indication from the wearer and/or a third party that the system should determine the current heart rate.

In various embodiments, the system may determine the current heart rate after a predefined time period. In some embodiments, the system may determine the current heart rate when a sensor detects movement and/or activities of the wearer (e.g., sitting, lying down, standing, driving a vehicle, flying in an airplane, walking, running, lifting, exercising, etc.). For example, the system may determine the current heart rate when the sensor detects that the wearer is driving a vehicle as determined by the speed at which the wearer is currently traveling.

The system may, in some embodiments, determine the current heart rate multiple times (e.g., measure the current heart rate from the heart rate monitor three times) to create an average current heart rate. In various embodiments, in addition to determining the current heart rate of the wearer, the system may determine other current physiological attributes of the wearer (e.g., pupil size, oxygen level, blood sugar level, the wearer's gaze and/or changes thereto, perspiration level, respiratory rate, brain wave activity, blink rate, free of physical injuries, injured, asleep, awake, conscious, unconscious, alive, deceased, stable, good, fair, serious, critical, distressed, etc.). In some embodiments, the system may be configured to determine the current heart rate from the heart rate monitor at the same time that it determines one or more current physiological levels from a second sensor. For example, the system may be configured to receive a current heart rate at the same time that it receives a head position measurement from the gyroscope.

In particular embodiments, the system may determine the current heart rate to be an elevated heart rate. In various embodiments, the system may determine the current heart rate to be a normal heart rate. In particular embodiments, the system may determine the current heart rate to be a first particular heart rate for a first period of time and a second particular heart rate for a second period of time.

The system, at Step 325, compares the current heart rate of the wearer to the baseline heart rate of the wearer. In various embodiments, the system compares the wearer's current heart rate to the wearer's baseline heart rate substantially automatically after the system determines the current heart rate of the wearer. In some embodiments, the system may compare the wearer's current heart rate to the wearer's baseline heart rate periodically (e.g., by the second, by the minute, hourly, daily, weekly, monthly, etc.). For example, the system may compare the wearer's current heart rate to the wearer's baseline heart rate every thirty minutes throughout the day. In other embodiments, the system may compare the wearer's current heart rate to the wearer's baseline heart rate after receiving an indication from the wearer or a third party that the system should compare the wearer's current heart rate to the wearer's baseline heart rate. In various embodiments, the system may receive an indication from the wearer and/or a third party of when to have the system compare the wearer's current heart rate to the wearer's baseline heart rate. For example, the system may receive an indication from the wearer to have the system compare the wearer's current heart rate to the baseline heart rate of the wearer at 6:00 a.m. and at 2:30 p.m. on a particular day.

In various embodiments, the system may compare the wearer's current heart rate to the wearer's baseline heart rate to determine if the wearer's current heart rate deviates from the wearer's baseline heart rate. In particular embodiments, the wearer's current heart rate may not deviate from the wearer's baseline heart rate. In some embodiments, the wearer's current heart rate may deviate from the wearer's baseline heart rate. In particular embodiments, the system may detect one or more deviations from the wearer's baseline heart rate. In various embodiments, the system may determine the wearer's current heart rate deviates from the wearer's baseline heart rate based on a predetermined percentage. For instance, the system may determine a wearer's current heart rate deviates from the wearer's baseline heart rate if the wearer's current heart rate is 10% faster than the wearer's baseline heart rate. In particular embodiments, the system may store the comparisons in an account associated with the wearer. In some embodiments, the comparisons may be accessible by the wearer and/or a third party. For instance, the comparisons may be diagramed in a chart that is accessible from the wearable device or from a computing device by the wearer's employer.

At least partially in response to comparing the current heart rate of the wearer to the baseline heart rate of the wearer, at Step 330, the system determines a current alertness level of the wearer. In particular embodiments, the system may determine the current alertness level of the wearer by calculating an amount of time it takes the current heart rate of the wearer to return from an elevated heart rate that results from the one or more stimuli to about the baseline heart rate of the wearer. In some embodiments, the system may set a predetermined amount of time that it takes the current heart rate of the wearer to return from an elevated heart rate to about the baseline heart rate of the wearer as a normal amount of time. In particular embodiments, the system may set a range of time as a normal amount of time for the wearer's heart rate to return from the elevated heart rate to the baseline heart rate. For example, the predetermined amount of time may be a range between 60 seconds and 300 seconds. In various embodiments, the system may determine whether the amount of time it takes the current heart rate of the wearer to return from the elevated heart rate that results from the one or more stimuli to the baseline heart rate of the wearer is above a particular heart rate threshold value. In particular embodiments, the system may determine the current alertness level of the wearer to be a particular alertness level for a particular period of time. For example, the system may determine that the wearer has been awake for over 15 hours.

In some embodiments, the system may determine the wearer's level of alertness based on the amount of time that it takes for the wearer's current heart rate to return to a particular deviation from the wearer's baseline heart rate. For example, the wearer's alertness level may be determined based on the amount of time it takes the wearer's current heart rate to fall to within a 5% range about the wearer's baseline heart rate. In particular, if the wearer's baseline heart rate is 75 beats per minute and the current hear rate is 120 beats per minute, then the system may determine the amount of time it takes for the current heart rate to get to within 5% of the baseline heartrate (e.g., 79 beats per minute.

In various embodiments, the system may determine the current alertness of the wearer based on the one or more physical attributes of the wearer (e.g., pupil size, heart rate, perspiration level, respiratory rate, brain wave activity, free of physical injuries, injured, asleep, awake, conscious, unconscious, alive, deceased, stable, good, fair, serious, critical, distressed, etc.).

In particular embodiments, the system may store the current alertness of the wearer in an account associated with the wearer. In some embodiments, the current alertness of the wearer may be accessible by the wearer and/or a third party. For instance, the current alertness of the wearer may be diagramed in a chart that is accessible from the wearable device or from a computing device by the wearer's supervisor. In various embodiments, the system may store the current alertness of the wearer in the Database 140.

At Step 335, the system notifies the wearer of the wearer's current alertness level. In various embodiments, the system may notify a third party of the wearer's current alertness level. In particular embodiments, the system may notify the wearer and/or a third party when the wearer's current alertness deviates from the wearer's baseline alertness. In some embodiments, in addition to notifying the wearer, the system may update the wearer's account to note that a notification was sent. In particular embodiments, the system may notify the wearer of the deviation from the baseline alertness by displaying an image on the lens of the eyewear. In other embodiments, the system notifies the wearer of the deviation from the baseline alertness by communicating through a speaker to the wearer. In various embodiments, the system may notify the wearer of the deviation from the baseline alertness by sending an electric shock to the wearer. In particular embodiments, the system may notify the wearer by generating an alert from one or more of the following vehicle systems: (1) in-cabin climate control; (2) audio system; (3) engine; (4) in-cabin lighting elements; and (5) brakes. By being operatively coupled to the one or more vehicle systems, the system may be configured to generate one or more alerts such as: (1) turning up or down the volume on the vehicle's audio system; (2) disabling the driving functionality of the vehicle; (3) turning up or down the temperature on the vehicle's in-cabin climate control; (4) turning on or off the lights in the vehicle's cabin; (5) applying the brakes on the vehicle, (6) etc.

In some embodiments, the system notifies the wearer and/or the third party of the deviation from the baseline alertness by sending a notification to the wearer's and/or the third party's mobile device. In particular embodiments, the system notifies the wearer and/or the third party of the deviation from the baseline alertness by email and/or text message. In other embodiments, the system may notify the wearer and/or the third party of a single deviation from the normal alertness substantially immediately after the system detects the deviation between the wearer's current alertness as compared to the wearer's normal alertness.

In various embodiments, the system may notify the wearer and/or the third party of the deviation from the normal alertness after a particular event. For example, the system may notify a third party of the wearer's current alertness if the system determines that the wearer's vehicle has swerved. In some embodiments, the system may notify the wearer and/or the third party of the deviation from the normal alertness after a particular period of time. For instance, the system may notify the wearer of the deviation from the wearer's normal alertness to a current alertness of drowsy after one minute of detecting the wearer being drowsy. In particular embodiments, at least partially in response to determining that the amount of time it takes the current heart rate of the wearer to return from an elevated heart rate that results from the one or more stimuli to about the baseline heart rate of the wearer is above a particular heart rate threshold value, the system may generate an alert that the wearer is tired.

In various embodiments, at least partially in response to determining that the wearer has experienced an impact, the system may notify one of the wearer or a third party that the wearer has experienced an impact. For example, if the wearer becomes drowsy and experiences an impact due to the vehicle's airbag deploying caused by the vehicle being involved in an accident, the system may notify the wearer's supervisor that the wearer has experienced an impact.

In various embodiments, in addition to notifying the wearer of the deviation from the normal alertness, the system may also provide suggestions to the wearer on how to change the wearer's current alertness to make it conform to the wearer's normal alertness. For instance, where the wearer's normal alertness while driving is alert and attentive and the wearer's current alertness while driving is drowsy, the system may suggest for the wearer to pull the vehicle over and rest. In some embodiments, the system may also provide suggestions to the wearer on the cause of the wearer's current alertness level. For example, where the wearer's normal alertness is alert and the wearer's current alertness is drowsy, the system may provide a suggestion to the wearer that the cause of the wearer's current alertness may be fatigue or a more serious medical issue such as depression based on the wearer's frequency of being drowsy. In addition to using the wearer's heartbeat to determine the wearer's level of alertness, the system may use information about one or more of the wearer's pulse oximeter lever, blood pressure level, pupil response, etc. to determine the cause of the wearer's alertness level.

In various embodiments, the system, when executing the Alertness Monitoring Module 300, may omit particular steps, perform particular steps in an order other than the order presented above, or perform additional steps not discussed directly above.

For instance, if a wearer does not need a temperature sensor or other particular sensor, the sensor may be removed from the eyewear.

Exemplary User Experience

Monitor Driver Alertness

In a particular example of a wearer using the Alertness Monitoring Module 300 to determine their alertness, the wearer may put on the wearable device (e.g., computerized eyewear) as the wearer enters a vehicle to begin driving. During this time, the system tracks the alertness of the wearer using the system's heart rate sensor, orientation sensor(s), brainwave activity sensor, blink rate sensor, oxygen sensor, infrared LED, photodiode sensor, EOG sensor, front-facing camera, and/or eye-facing camera. The wearer may begin by having the system take a baseline measurement of the wearer's heart rate while the wearer is looking straight ahead out of the windshield of the vehicle. The wearer's baseline heart rate may be determined to be in the normal range for an individual with a similar height, weight, sex, age, etc. The system then tracks the heart rate of the wearer to determine any changes in the wearer's heart rate. If the wearer's heart rate remains relatively unchanged for a predetermined period of time, the system may stimulate the wearer's heart rate by producing a vibration from the wearer's cellphone. If the wearer's heart rate remains above a predetermined heart rate threshold for longer than a predetermined period of time, the system may determine that the wearer is drowsy or that the wearer's level of alertness is impaired from an expected level of alertness. The system may alert the wearer that the wearer is drowsy by decreasing the temperature in the vehicle driven by the wearer. This may cause the wearer to again become alert. If the wearer does not become appropriately alert, the system may generate an alert to a computing device associated with a third party, such as a supervisor for the wearer. In another example, the wearer's blink rate and/or blink frequency may increase or decrease based on the wearer's alertness level. For instance, where the wearer has become tired, the wearer's frequency of blinks may decrease as the wearer's eyes remain closed for longer periods of time or remains open and fixated as the wearer's level of alertness is diminished. The system may then determine that the wearer's current alertness deviates from the wearer's normal alertness. In response to determining a particular deviation from the wearer's normal alertness level (e.g., as determined by changes in the wearer's blink rate), the system may emit a sound, or other alert, to notify the wearer (or other individual) that the wearer's alertness level is too low to be driving.
