This disclosure relates to the field of healthcare diagnostics and treatment, and more particularly to cloud-based healthcare diagnostics and treatment.
Research in medicine and psychology has improved our understanding of neurological function, but has failed to make significant progress in identifying and treating neurological conditions, especially in terms of preventing early cognitive decline and the onset of neurological disorders such as dementia. This lack of significant means to detect and improve neurological conditions has become increasingly important as lifespans in many parts of the world have increased. As the average age of populations has risen, cognitive issues such as dementia have become more common, and advances in identification and treatment have not kept pace. The lack of significant ability to identify and treat neurological conditions affects younger populations, as well, where mental issues such as depression can take a significant toll.
Research highlights the importance of continued neurological stimulation throughout all stages of life including stimulation through physical activity, social connection, and frequent cognitive challenge, but we still lack means for identifying and treating neurological disorders, especially in their early stages. Advancements in and virtual reality systems and environments have created new opportunities for immersive virtual experiences. However, this potential for immersive virtual experiences has not been used for much beyond computer gaming. Further, while virtual reality gaming platforms exist, including multi-person gaming platforms, none are capable of gathering health-related data about players during operation.
Further, medical diagnostics currently tend to involve unpleasant activities such physical exams, blood analysis, x-rays, MRIs, in the case of physical ailments, and verbal interviews and repetitive and boring on-paper or computer-based repetitive testing for neurological issues. All such current medical diagnostics are performed on a periodic basis, requiring doctors, nurses, and other medical professionals, so either cannot be performed regularly or are expensive to perform regularly. Medical treatment for physical issues tends to be prescription of diet, exercise, and medication, but implementation of these treatments is left to the patient, leading to lack of adherence with the recommendation. Medical treatment for neurological issues tends to be prescription of medication and is disconnected from treatment for physical issues. All of these diagnostic and treatment methodologies are tedious for the patient and adherence to recommendations and prescriptions can be low.
What is needed is cloud-based healthcare diagnostics and treatment platform capable of making non-invasive healthcare diagnostics and treatment recommendations based on data captured from combinations of physical activity and mental activity.
Accordingly, the inventor has conceived and reduced to practice, a cloud-based healthcare platform capable of making non-invasive healthcare diagnostics and treatment recommendations based on data captured from combinations of physical activity and mental activity. In an embodiment, the system and method comprise a healthcare diagnostics and treatment module comprising a HIPAA-compliant security gateway, an AI-assisted healthcare diagnostics module, and an alert and treatments module. The HIPAA-compliant security gateway separates out health-related data from streams of data which may include other data such as game data, provides the health-related data to the AI-assisted healthcare diagnostics module which performs diagnoses of the health-related data using machine learning algorithms, and provides the diagnoses to the alert and treatments module which generates alerts and treatments based on the diagnoses.
According to a preferred embodiment, a cloud-based healthcare platform, comprising: a network-connected computing device comprising a memory and a processor; a security gateway comprising a first plurality of programming instructions stored in the memory which, when operating on the processor, causes the network-connected computing device to: establish a Health Insurance Portability and Accountability Act (HIPAA)-compliant health data tunnel with a remote computing device; direct the remote computing device to send health-related data about a user to the security gateway via the HIPAA-compliant health data tunnel, the health-related data comprising information about a physical activity of the user or a mental activity of the user, or both; and store the health-related data in a patient database; an AI-assisted healthcare diagnostics module comprising a second plurality of programming instructions stored in the memory which, when operating on the processor, causes the network-connected computing device to: retrieve the health-related data about the user from the patient database; process the health-related data through a machine learning algorithm to diagnose a condition of the user, the condition comprising an aspect of the user's physical function, or the user's mental function, or both, is disclosed.
According to another preferred embodiment, a method for operating a cloud-based healthcare platform, comprising the steps of: using a security gateway operating on a network-connected computing device comprising a memory and a processor to: establish a Health Insurance Portability and Accountability Act (HIPAA)-compliant health data tunnel with a remote computing device; direct the remote computing device to send health-related data about the person to the HIPAA-compliant security gateway via that HIPAA-compliant health data tunnel, the health-related data comprising information about a physical activity of a user or a mental activity of the user, or both; and store the health-related data in a patient database; using an AI-assisted healthcare diagnostics module operating on the network-connected computing device to: retrieve the health-related data about the person from the patient database; process the health-related data through a machine learning algorithm to diagnose a condition of the person, the condition comprising an aspect of the person's physical function, or the person's mental function, or both, is disclosed.
The accompanying drawings illustrate several embodiments of the invention and, together with the description, serve to explain the principles of the invention according to the embodiments. It will be appreciated by one skilled in the art that the particular embodiments illustrated in the drawings are merely exemplary, and are not to be considered as limiting of the scope of the invention or the claims herein in any way.
The inventor has conceived, and reduced to practice, a cloud-based healthcare platform capable of making non-invasive healthcare diagnostics and treatment recommendations based on data captured from combinations of physical activity and mental activity. In an embodiment, the system and method comprise a healthcare diagnostics and treatment module comprising a HIPAA-compliant security gateway, an AI-assisted healthcare diagnostics module, and an alert and treatments module. The HIPAA-compliant security gateway separates out health-related data from streams of data which may include other data such as game data, provides the health-related data to the AI-assisted healthcare diagnostics module which performs diagnoses of the health-related data using machine learning algorithms, and provides the diagnoses to the alert and treatments module which generates alerts and treatments based on the diagnoses.
Advancements in and virtual reality systems and environments have created new opportunities for immersive virtual experiences. However, this potential for immersive virtual experiences has not been used for much beyond computer gaming. Further, while virtual reality gaming platforms exist, including multi-person gaming platforms, none are capable of gathering health-related data about players during operation. There is a great deal of health-related data that could be gathered from computer gaming systems, but which is not captured because systems are not configured to capture that data as health-related data. Further, specialized equipment can be utilized to expand and enhance the health-related data captured as an invisible and seamless integration with computer gaming systems. Multi-player gaming expands the types of health-related data that can be collected to include social interactions such as in-game chats and messaging between team players through the online gaming system. Systems and methods for capturing this health-related data during game play are described herein.
As lifespans have improved in the past few decades, particularly in more developed countries, the mean and median age of populations have increased. The greatest risk factor for neurodegenerative diseases is aging, so older persons are more likely to suffer from degenerative diseases and conditions affecting the nervous system such as amyotrophic lateral sclerosis, Parkinson's disease, Alzheimer's disease, fatal familial insomnia, Huntington's disease, Friedreich's ataxia, Lewy body disease, and spinal muscular atrophy. It has been estimated that some 20-40% of healthy people between 60 and 78 years old experience discernable decrements in cognitive performance in one or more areas including working, spatial, and episodic memory, and cognitive speed. Early stages of neurodegenerative diseases are difficult to detect, the causes of such diseases are not well understood, and treatments for such diseases are non-existent.
Without using one of the costly brain scan technologies, it remains difficult to detect, assess, and treat poor functioning of the nervous system, whether such poor functioning is due to injury to the brain, neurodegenerative disease, psychological or physical trauma, or changes in brain chemistry, diet, stress, substance abuse, or other factors. For certain neurological conditions, such as Chronic Traumatic Encephalopathy (CTE), none of the current brain scan technologies are able to reliably capture diagnostic data. Other neurological deficits and conditions can be evaluated or diagnosed using assessments using readily available equipment and observational analysis, such as the Cognitive Performance Test (CPT) and Timed Up and Go Test (TUG) but lack the sensitivity suitable for nuanced or early deficit detection. Each of these types of poor nervous system function can impact different parts of the brain and/or nervous system in different ways. Due to the complexity of interactions in the nervous system and the brain's ability to adapt its function in many areas, it remains difficult to detect poor functioning and to identify which neurological functions and anatomical aspects and regions are impacted early enough to implement an effective treatment protocol.
However, recent research studies have demonstrated that physical activity, especially aerobic exercise, can improve neurogenesis and other neurological functions, whether related to physical brain and nervous system impairments or mental health/emotional issues. In addition, evolutionary biologists have hypothesized that early humans began their cognitive revolution when they ventured into the African savannah and started walking upright. In fact, more recent research studies on the cerebellum, an ancient part of the brain that coordinates the motor control, have discovered unexpected connections between the cerebellum and other parts of the brain. Specifically, according to a team of researchers from the University of Washington, only percent of the cerebellum connections was dedicated to areas involved in physical motion, while 80 percent was connected to areas involved in functions such as abstract thinking, planning, emotion, memory and language. The cerebellum doesn't actually execute tasks like thinking, just as it doesn't directly control movement. Instead, it monitors and coordinates the brain areas that are doing the work and makes them perform better.
Therefore, simultaneous testing of primary physical tasks such as walking or running and the associative activities that include various mental, other physical activities as well as emotional experiences (commonly known as a dual task assessment), and the correlation of results therefrom can be used to evaluate specific neurological functional areas to create a profile of relative neurological functioning and see where deficiencies may be present. Therefore, changes in a person's walking gait while the person is engaged in other associative activities like solving a logic puzzle could be analyzed and compared against the normal or average dual-tasking costs of the same population group for relative functioning as well as anomalies. Such anomalies for the given brain functions or regions could be indicative of abnormal central nervous system functions. Further, the combination of the dual-tasked physical and associative activities can help identify the abnormally-performing neurological functions or even help isolate affected neurological regions. For example, a walking gait/logic puzzle dual-task activity may indicate normal functioning in a given individual, indicating that autonomous physical activity and cognition are not affected. However, in the same individual another dual task of walking and listening within a virtual reality (VR) environment may result in gait changes or a complete stop of the walk as the neurological functions required for these tasks are different from walking and logic. In this case, it may indicate that there may be injury to or degeneration of the auditory cortex of the temporal lobe, potentially informing further diagnostic procedures. As a result, a system combining numerous combinations of various dual-tasking activities, covering all neurological functions or regions, may be able to evaluate, detect, and treat neurological deficits and conditions even before they become noticeably symptomatic. For individuals for whom symptoms are already present, such a system can evaluate and track changes over time, and potentially slow down or reverse the progression of such deficits and conditions.
Using this same dual-tasking analysis, it is also possible to evaluate, detect, and treat neurological conditions and changes involving mental health and emotional issues. For example, elevated heart rate, elevated blood pressure, or chest pain during exercise that are higher than an individual's normal history for these indicators can indicate emotional stress. The addition of story-telling or emotional experiences through computer games and/or simulations (and especially when such experiences are virtual-reality experiences) can help to elicit emotional and physiological responses or lack thereof. For example, a veteran suffering from PTSD (Post-Traumatic Stress Disorder) could be trained inside such a dual-tasking VR environment so that s/he can gradually regain her/his agency by overcoming progressively challenging physical and emotional scenarios—reactivating her/his dorsolateral prefrontal cortex and lateral nucleus of thalamus with the help of these combined physical and emotional activities (likely using parallel but not war-based scenarios). As a result, the veteran could potentially extricate herself or himself from such traumatic experiences by developing her/his closure stories.
The integration of a primary task with an associative activity is also especially well-suited for the evaluation and conditioning of specific aspects of neurological functioning in individuals training for physical, mental, or combined forms of competition. After an initial array of primary physical challenges and associated tasks designed to evaluate specific neurological functioning areas to create a profile of relative functioning a more thorough understanding of the competitor's strengths and weaknesses in their specific mode of competition can be achieved. With the help of a conditioning recommendation algorithm, expert input, and competitor input a regimen of primary and associative tasks specifically suited to improve performance of that competitor and mode of competition can be administered at prescribed or chosen frequency. Digital challenges can further be customized for competition and competitor specificity as the conditioning recommendation algorithm analyzes the efficacy of conditioning regimens for users aiming to improve in similar neurological functions, the specific user's response to conditioning inputs over time, and expert recommendations for users with similar neurological functioning profiles and objectives.
One form of treatment that may be used to treat neurological conditions is brainwave entrainment, which is readily integrated into many aspects of gaming. Depending on configuration, the system and method may comprise a display comprising virtual objects, a light-producing device (other than the display), an audio-producing device such as speakers or headphones, a haptic feedback device such as a vibratory motor, a means for monitoring the user's attention, and a software application which applies brainwave entrainment using some combination of the display, the light-producing device, the audio-producing device, and the haptic feedback device. In some embodiments, the brainwave entrainment may be based in part on the monitoring of the user's attention. In some embodiments, virtual objects on the display may be used to provide brainwave entrainment. Some embodiments may comprise additional components such as an entrainment routine selector which adjusts the brainwave entrainment based on certain inputs, biometric sensors such as an electroencephalograph which may be used to provide inputs to the software application or entrainment routine selector. In some embodiments, brainwave entrainment may be applied using combinations of brainwave entrainment from virtual objects on the display and physical stimulation transducers such as the light-producing device, the audio-producing device, and the haptic feedback device. In some embodiments, the software application is a virtual reality environment, and the display may be a virtual reality headset or other virtual reality display hardware.
Brainwave entrainment may be further enhanced by shared experiences such as online, multiplayer gameplay. A multi-person platform not only allows brainwave enhancement of multiple users simultaneously, the shared experience can enhance brainwave enhancement by participation in a common activity with like-minded persons. Some exemplary embodiments and descriptions herein describe use of the platform for gaming purposes. Some common types of multi-person virtual experiences that could be enhanced with brainwave entrainment using the platform include first person shooters, role-playing games, adventure games, real-time simulations, and collectible card games. However, the platform's usage is not limited to gaming. The platform can be configured to apply brainwave entrainment in any type of multi-person virtual experience, some examples of which include virtual group meditation sessions, virtual group kaleidoscope visualizations, simulations of real activities such as hiking and rock climbing, and simulations of non-real activities such as flying or using magic. Brainwave entrainment can either be similar or the same for all users, or can be applied differently to each user. Further, the virtual nature of the experiences can allow for shared overall experiences or engagement in a common activity while customizing the visual, auditory, and brainwave entrainment experience for each user.
Implementations of visual brainwave entrainment to date have been limited to passive visual stimulation using physical lights (typically light emitting diodes, or LEDs). There is no interactivity or active engagement with the visual stimulation transducers, which makes the process less effective and uninteresting. Further, the visual stimulation transducers, being physical objects, cannot be changed in terms of size or shape, cannot be modified in reaction to user feedback, and are limited in terms of colors available, are generally fixed in place, and additional lights cannot be added to the system without physically connecting (and likely programming) additional lights.
Virtual objects, on the other hand, have none of these limitations, and can be used as visual stimulation transducers while users are engaged with an on-screen display. Brainwave entrainment using virtual objects provides essentially unlimited variability in terms of stimulator sizes, shapes, colors, movements, rotations, etc., and allows for the use of multiple stimulators simultaneously, each with different characteristics. Any change to a virtual object that is perceptible to a user and can be applied at a repeating frequency may be used to apply brainwave entrainment.
Further, gamification changes the brainwave stimulation from passive receipt of light therapy to active engagement with the visual stimulation objects, wherein the user's brain is actively stimulated during the activity, enhancing the effectiveness of the stimulation. Further, as the user is actively engaged with the game, stimulation can be applied based on where the user's attention is focused. Attention-based stimulation provides opportunities for both direct stimulation (e.g., flashing an object at which the user is looking, playing sounds or providing haptic feedback associated with a game object or activity that is the object of the user's attention, etc.) and indirect stimulation (e.g., flashing an object in the user's periphery of vision, playing sounds or providing haptic feedback associated with the game, but not the object of the user's attention such as a background element, background music or sounds, etc.). For example, eye tracking technology can be used to determine where the user is looking on the screen at any given time, and objects at which the user is looking can be used to provide visual stimulation even if the user changes his or her attention to a different object on the screen. The user's attention to objects on the screen can be monitored over time to determine whether the user is remaining focused on the activity, or is getting tired and losing focus, and the determined level of user attention can be used to change the type, intensity, directness, and other characteristics of the stimulation. Other means of determining the user's attention may be used such as assuming that the user's attention is focused on an object with which the user has just interacted.
Brainwave entrainment using virtual objects may be further enhanced by using multiple objects, each capable of providing complementary types of stimulation, and/or by intentionally directing the user's attention to objects providing certain types of stimulation. For example, if the user is playing a first person shooter (FPS) game that involves shooting attacking aliens, the user's attention will naturally be focused on finding attacking aliens, aiming at them, and shooting them. As each alien will be the focus of the user's attention sequentially, the alien at which the user is currently looking may be flashed at appropriate frequencies and in appropriate colors to provide appropriate brainwave stimulation. Simultaneously, other objects on the screen (or even the background) may be selected to provide a complementary visual stimulation in the periphery of the user's vision. Further, brainwave entrainment using virtual objects may be enhanced by selecting multiple treatment modalities (e.g., light, sound, vibration, electrical stimulation) applied either simultaneously or sequentially, by varying the frequency or frequencies of brainwave entrainment (e.g., from about 0.5 Hz to about 100 Hz), and by varying the intensity and/or scale of the treatment (e.g., from subtle, localized vibrational or electrical stimulation to area-wide, intense stimulation such as high-intensity room lighting and sound).
Brainwaves are frequencies at which electrical impulses in the brain occur. Brainwave frequencies change based on the state of consciousness of the user (e.g., sleeping, awake, dreaming, concentrating, relaxed, contemplative, meditative, irritated, etc.). Generally speaking, brainwaves are divided into five categories with frequencies roughly in the following ranges.
Delta waves are brainwaves in the general frequency range of 0.1 Hz to 4 Hz. Delta waves occur during deep sleep, and indicate a low level of arousal. Theta waves are brainwaves in the general frequency range of 4 Hz to 8 Hz. Theta waves occur in a state between wakefulness and sleep, such as during daydreaming and meditation, and can indicate drowsiness, creativity, or imagination. Alpha waves are brainwaves in the general frequency range of 8 Hz to 12 Hz. Alpha waves occur during a waking state, but are associated with relaxation, problem solving, analysis, and decision-making. Beta waves are brainwaves in the general frequency range of 12 Hz to 30 Hz. Beta waves occur during alertness, concentration, and strenuous mental activities such as solving mathematical problems and planning for the future. Gamma waves are brainwaves in the general frequency range of 30 Hz to 44 Hz. Gamma waves are associated with high-level information processing. There is evidence of Lambda brainwaves in a range around 47 Hz to 70 Hz, and other brainwave entrainment frequencies may be useful up to around 100 Hz. These ranges are approximate, and there is some overlap between them.
There are many promising uses of brainwave entrainment. One promising use of brainwave entrainment is to treat and/or prevent epilepsy. There is some evidence that epileptic seizures occur when the brain falls into theta wave activity (approximately 4 Hz to 8 Hz) during normal waking consciousness. Normal waking consciousness is typically associated with beta wave brain activity (12 Hz to 38 Hz). Performing brainwave entrainment at beta wave frequencies on persons with epilepsy may help prevent them from falling into theta wave brain activity, thus preventing seizures.
Another possible use for brainwave entrainment is to reduce agitation by performing brainwave entrainment at alpha wave frequencies (approximately 8 Hz to 12 Hz). Alpha wave frequencies are those brain wave frequencies between theta wave activity (typically associated with dreaming) and beat wave activity (typically associated with concentration and learning). Alpha wave frequencies are associated with relaxation and calmness. Therefore, brainwave entrainment at alpha wave frequencies may help induce relaxation and calmness.
Many different wave forms and/or pulse widths may be used in delivering entrainment at the selected frequency or frequencies, regardless of the modality (light, sound, etc.) of the stimulation. Wave forms may include, but are not limited to, rectangular wave forms, sine wave forms, triangular wave forms, and sawtooth wave forms. Pulse widths or duty cycles at any given frequency may be varied across the entire range of the frequency period. For example, at a given frequency, the duty cycle of each period of the frequency can be varied from nearly 0% on-time/100% off-time to nearly 100% on-time/0% off-time. Thus, for a given frequency, the stimulator (e.g., light) can be on and off for an equal amount of time in each period (a 50% duty cycle), mostly on during each period (e.g., a 75% duty cycle), or mostly off during each period (e.g., a 25% duty cycle). In these cases, the frequency of the stimulation is the same, but the amount of on-time of the stimulation in each period of the frequency is different.
Different pulse widths or duty cycles may be useful, depending on the circumstances. For example, when engaged in a mental task that requires visual acuity, a very low or very high duty cycle may be used to flash a light stimulator at a pulse width that can be captured by the human eye, but is not consciously recognizable. The human eye can capture flashes of light as short as 1/200th of a second (equivalent to a frequency of 200 Hz), possibly shorter, but because of persistence of vision, cannot distinguish between repeated flashes of light at that frequency. Television and computer monitor frame refresh rates are typically 60 Hz or above, as this is a frequency at which persistence of vision makes it difficult to distinguish between frames. Thus, for example, the flicker of light stimulation at a frequency of 40 Hz and a 50% duty cycle would be easily perceivable by most human beings as each “on” pulse is 1/80th of a second long and separated by another “off” time of another 1/80th of a second. However, the flicker of light stimulation at the same frequency, but at a 80% duty cycle would likely not be consciously perceptible, as the “on” time of each period would last about 1/50th of a second and the “off” time of each period would last about 1/200th of a second. Thus, the “off” time of each period is within the limits of capture by the human eye (200 Hz), but would likely not be consciously perceptible because it is above the average frequency resolution (60 Hz) of the human eye, and the light would appear to the conscious mind to be on all the time.
In a similar manner, pulse widths or duty cycles may be adjusted to be perceptible to certain cells in the eye but not others. The human eye has two different types of light receptors: cones and rods. Cones are the dominant light receptors used under daylight conditions, and reception of light by cones is called photopic vision. Cones are able to distinguish colors, but are less sensitive to lower light intensity and the persistence of vision of cones is greater (meaning that the frequency of pulses that can be distinguished by cones is less than for rods). Rods are the dominant light receptors used at night and under low-light conditions, and reception of light by rods is called scotopic vision. Rods are not able to distinguish colors, but are more sensitive to lower light intensity and the persistence of vision of rods is less (meaning that the frequency of pulses that can be distinguished by rods is greater than for cones). Cones are greatly concentrated in the center of vision (where the person is directly looking) while rods are considerably more dominant in the periphery of vision. This difference in the type of light receptors in the eye can be used to advantage when selecting either a frequency of stimulation or a pulse width/duty cycle of that frequency. Again using the example above where visual acuity is required for a mental task, the pulse width or duty cycle of each period of a brainwave entrainment frequency of light can be selected to be perceptible to rods but not to cones, thus allowing the brainwave entrainment frequency of light to be perceived by the brain (through the rods in the periphery of vision which have a greater frequency resolution), but not consciously perceptible to the person (who is primarily focused on the light received by the cones (in the center of vision and with a lesser frequency resolution).

The phrase “game play data” means any and all data associated with a user's interaction with a game such as, but not limited to, the location and movement of the user's cursor, pointer, avatar, or other representation in a game; the user's interaction with, or manipulation of, objects or environmental elements in a game; the inventory or items held by a user; game progress or story progress data; and statistics or scoring data such as game scores, hit rates and success rates, game progress indicators; and trophy or award accumulations.
The term “gamification” as used herein means the application of brainwave entrainment using a game or a game application.
The phrases “neurological functioning” and “neurological function” as used herein mean any and all aspects of neuroscience and neurology where input, output, processing, or combination thereof involve aspects of the nervous system. These include but are not limited to functional as well as anatomical aspects of cognitive, sensory, motor, emotional, and behavioral functions and experiences.
The phrase “primary task” as used herein means a first task or activity to be engaged in by an individual under assessment. The primary task will often, but not always, be a physical task or exercise such as walking on a treadmill.
The phrase “pulse width” means the amount of time that a frequency signal is in the “high” or “on” state, expressed as a time period that is a portion of each full period (complete high/low cycle) of the frequency signal. Note that “duty cycle” and “pulse width” are two different means of expressing the same concept. The phrase “pulse width modulation” is often used to denote changing of the pulse width of a frequency signal.
The term “transducer” as used herein means a device that converts an electrical signal into variations in a physical quantity, such as sound, light, pressure, or electrical stimulation. A display is included in the definition of “transducer.”
The phrase “stimulation transducer” as used herein means a transducer used to stimulate one of the senses of a person or animal. Any portion of a display may be used as a stimulation transducer, non-limiting examples of which include virtual objects or backgrounds on the display.
The phrase “virtual object” means a computer-generated simulation of an object perceivable to a human being. Virtual objects include, but are not limited to, visible virtual objects such as two-dimensional and three-dimensional shapes shown on a display, non-visible virtual objects such as those that might be “felt” through haptic feedback (e.g., gloves equipped with haptic feedback equipment that provide resistance to the user's fingers around the contours of a virtual object in space), and any combination of the two (e.g., a visible virtual object displayed in a virtual reality environment through a VR headset which can also be “felt” by the user via haptic feedback). A virtual object does not have to be gamified and may be, for example, a virtual object displayed on a screen.
The phrase “virtual reality” means a computer-generated environment in which a person may participate as an actor in the environment via an avatar representing the person in the computer-generated environment. The phrase “virtual reality” includes all forms of such environments including where the entire environment is computer-generated and where the computer generated environment includes real-world elements, often referred to as “extended reality,” or “augmented reality.” The phrase “virtual reality” does not require the use of a virtual reality headset.
The brainwave entrainment manager 200 is the core of the system, and manages inputs from, and outputs to, other components of the system. It is responsible for selection of entrainment routines, evaluation of the user's attention, and activation of both virtual and physical stimulation transducers.
The therapy regimen controller 110 is an administrative interface that allows an administrator (e.g., a physician, therapist, masseuse, or other service provider) to select therapy regimens for application to the user (who may be a patient, client, etc., of the administrator). The therapy regimen controller 110 may be used, for example, to select a regimen for brainwave entrainment that emphasizes alpha wave stimulation to induce relaxation in an overstimulated user.
The biometric sensors 120 are sensors that measure a physical or physiological characteristic of the user, such as heart rate, temperature, sweat production, brain activity (using an electroencephalograph, or EEG), etc. Biometric sensors 120 are used to provide feedback to the brainwave entrainment manager 200 as to the physical or physiological state of the user, which may be used to infer the user's mental state. For example, a biometric sensor 120 that measures the user's heart rate may be used to infer the user's level of relaxation (or lack thereof), thus providing feedback as to the effectiveness of alpha brainwave entrainment intended to induce relaxation.
Spatial sensors 130 are sensors that measure a user's physical location in space or a location at which the user is focusing his or her attention. For two dimensional screens, eye movement may be tracked and the location of the user's gaze may be calculated. In the case of virtual reality (VR), the user's body may be tracked, or if the user is wearing a VR headset, the orientation of the headset can be used to detect the user's head movements. Spatial sensors 130 are used to detect the user's engagement with virtual objects and virtual environments, such that brainwave entrainment using those objects and environments can be adjusted, accordingly.
The VR application 140 is used for gamification of brainwave entrainment. While a VR application 140 is shown here, in principle any computer game, puzzle, display, or animation can be used, whether interactive or not, and whether three-dimensional or two-dimensional. The VR application 140 can be a specially-designed program intended for use with the system, or can be an off-the-shelf game or application adapted for use with the system. In either case, the VR application 140 will either have an interface with the brainwave entrainment manager 200, or will have a brainwave entrainment manager 200 integrated into it, whereby the brainwave entrainment manager 200 is used to control brainwave entrainment using the virtual objects in the VR application 140.
The external transducers 150 are physical stimulation transducers that may be used to complement brainwave entrainment using virtual objects. A non-limiting list of external transducers 150 includes lights or LEDs, speakers or other audio-producing devices, vibratory or other pressure-producing devices, and electrical stimulators. As an example, while brainwave entrainment is being applied visually using virtual objects on a screen, the brainwave entrainment may be supplemented or complemented by audible brainwave entrainment using speakers.
The display 160 may be any type of display producing an output visible to a user of the system. A non-limiting list of displays 160 includes computer and tablet screens, VR headsets, and projectors. The display 160 is the means by which visual brainwave entrainment may be applied using virtual objects.
The user's attention need not be tracked via a camera, and may be tracked through other means. For example, the user's attention may be tracked by monitoring the user's interaction with the virtual objects or virtual environment in the form of mouse clicks, keyboard activity, orientation of the user's head or body (e.g., when a virtual reality headset is being used), orientation and/or movement of hand-held trackable devices such as game controllers with integrated accelerometers, gyroscopes, etc. In some embodiments, the user's attention may be tracked not in terms of visual direction or attention, but in the more general sense of focus, consistency, ability to concentrate, level of interest, response times, or other factors not necessarily associated with the direction of the user's vision. All of these things may be incorporated into decisions by the entrainment routine selector 201 as to changes to be made to the entrainment routine.
Simultaneously, the entrainment routine selector 201 may activate one or more external transducers 204 using an external transducer activator 204, where the entrainment routine selector 201 determines that external transducers may supplement or complement the brainwave entrainment using virtual objects. The entrainment routine selector 201 may further use feedback to determine whether the selected entrainment routine is having the desired effect. As an example, the entrainment routine selector 201 may use biometric feedback such as a user's heart rate (e.g., a lowering heart rate may be used to infer relaxation) to change the entrainment routine. For example, a lowering heart rate during alpha wave entrainment would likely indicate relaxation, in which case the entrainment routine would remain unmodified, but a rising heart rate would likely indicate irritation, in which case the entrainment routine might be modified by reducing the entrainment to theta wave entrainment to further induce relaxation.
Many other types and implementations of feedback are possible including, but not limited to, changing of entrainment routines based on user reactions to, or interactions with, virtual objects and virtual environments; user attention attributes such as the location, intensity, focus, and consistency of user attention to virtual objects and virtual environments; game scores and other gaming metrics; physical biofeedback such as monitoring heart rate, perspiration, respiration; cognitive biofeedback such as monitoring changes in an EEG; exercise equipment feedback such as treadmill speed, cycling cadence and/or power, rowing strokes per minute and/or power. Further, entrainment routines can be changed to use different types of stimulation (e.g., if the feedback indicates that visual stimulation is less effective at certain points in a game, it can be supplemented with auditory or haptic feedback). Multiple stimulation devices can be used to augment or supplement the visual stimulation including, but not limited to, haptic headbands or vest, speakers or headphones, and other stimulation devices. In this way, the system can be programmed to automatically adapt to users based on a variety of feedback sources.
Cloud-based gaming platform 1300 comprises frontend services 1310 and backend services 1320. Frontend services 1310 are accessible via a network connection (e.g., via the Internet) by game clients 1330, and comprise game platform services 1311 and game servers 1312. Game platform services 1311 provide services outside of game play such as leaderboards, group formation, lobbies, chat rooms, inventory management, and account management. Game servers 1312 are the hardware (real or virtual) on which the games are run. Game servers 1312 may be real or virtual, and dedicated or not, and distributed or not. The exemplary architecture of this diagram shows dedicated, non-distributed game servers (which may still be either real machines or virtual machines). Each game server 1312 of this embodiment further comprises a brainwave entrainment manager 1313 with functionality similar to brainwave entrainment manager 200 of earlier-described embodiments. In this embodiment, however, brainwave entrainment manager 1313 manages brainwave entrainment routines for a plurality of users engaging in a shared virtual experience. Backend services 1320 interface only with frontend services 1310 and are not directly accessible by game clients 1330. Backend services 1320 provide the storage and administrative functionality for the game and comprise an analytics stack 1321 and a game database 1322. Analytics stack 1321 allows for queries about game operations and statistics by gameplay programmers and designers, business managers, and customer service representatives. Game database 1322 stores all information about the game necessary for its operation including, but not limited to, locations, maps, activities of player characters and non-player characters, game states, and game events.
Game clients 1330 are software applications or web browsers operating on end-user computing devices which access cloud-based gaming platform 1300 to send and retrieve game-related data. Game clients 1300 may operate on any end-user device, three examples of which are smartphones 1331, personal computers (PCs) 1332, and gaming consoles or handheld devices 1333. Game clients 1330 access cloud-based gaming platform 1300 via a network connection (e.g., via the Internet or a local area network) exchange game-related data with frontend 1310 of cloud-based gaming platform 1300 and display the user's perspective of the game to the user of the device on which the game client is operating. Thus, each user sees a different perspective of the game from each other user. As will be further described below, in certain configurations this allows for a shared virtual experience or common activity along with a different gameplay feel or intensity and/or different brainwave entrainments for each user.
Cloud-based gaming platform 1400 comprises frontend services 1410 and backend services 1420. Frontend services 1410 are accessible via a network connection (e.g., via the Internet) by game clients 1430, and comprise game platform services 1411. Game platform services 1411 provide services outside of game play such as leaderboards, group formation, lobbies, chat rooms, inventory management, and account management. Backend services 1420 interface only with frontend services 1410 and are not directly accessible by game clients 1430. Backend services 1420 provide the storage and administrative functionality for the game and comprise an analytics stack 1421 and a game database 1422. Analytics stack 1421 allows for queries about game operations and statistics by gameplay programmers and designers, business managers, and customer service representatives. Game database 1422 stores all information about the game necessary for its operation including, but not limited to, locations, maps, activities of player characters and non-player characters, game states, and game events.
Game clients 1430 are software applications or web browsers operating on end-user computing devices which access cloud-based gaming platform 1400 to send and retrieve game-related data. Game clients 1400 may operate on any end-user device, three examples of which are smartphones 1431, personal computers (PCs) 1432, and gaming consoles or handheld devices 1433. Game clients 1430 access cloud-based gaming platform 1400 via a network connection (e.g., via the Internet or a local area network) exchange game-related data with frontend 1410 of cloud-based gaming platform 1400 and display the user's perspective of the game to the user of the device on which the game client is operating. Thus, each user sees a different perspective of the game from each other user. As will be further described below, in certain configurations this allows for a shared virtual experience or common activity along with a different gameplay feel or intensity and/or different brainwave entrainments for each user.
In this embodiment, an end-user device acts as the game server 1433 for one or more other game clients 1430. Game servers are the hardware (real or virtual) on which the games are run, in this case the physical hardware of the end-user device or a virtual machine operating on the end-user device. In this peer-to-peer gaming architecture, each game client 1431, 1433, 1435 further comprises its own on-device brainwave entrainment manager 1432, 1434, 1436 each with functionality similar to brainwave entrainment manager 200 of earlier-described embodiments. In this embodiment, however, each brainwave entrainment manager manages brainwave entrainment routines for the user of the device on which its associated game client is operating. Here, client B/game server 1433 accesses cloud-based gaming platform 1300 via a network connection (e.g., via the Internet or a local area network), exchanges game-related data with frontend 1410 of cloud-based gaming platform 1400, displays the user's perspective of the game to the user of client B/game server 1433, and shares the exchanged game-related data with other game clients 1431, 1435 for them to do the same for their users. Thus, each user sees a different perspective of the game from each other user, notwithstanding the fact that client B/game server 1433 is the only game server in connection with cloud-based gaming platform 1400. As will be further described below, in certain configurations this allows for a shared virtual experience or common activity along with a different gameplay feel or intensity and/or different brainwave entrainments for each user.
Frontend services 1710 are accessible via a network connection (e.g., via the Internet) by game clients 1730, and comprise game platform services 1711 and game servers 1712. Game platform services 1711 provide services outside of game play such as leaderboards, group formation, lobbies, chat rooms, inventory management, and account management. Game servers 1712 are the hardware (real or virtual) on which the games are run. Game servers 1712 may be real or virtual, and dedicated or not, and distributed or not. The exemplary architecture of this diagram shows dedicated, non-distributed game servers (which may still be either real machines or virtual machines). Each game server 1712 of this embodiment further comprises a brainwave entrainment manager 1717 with functionality similar to brainwave entrainment manager 200 of earlier-described embodiments. In this embodiment, however, brainwave entrainment manager 1717 manages brainwave entrainment routines for a plurality of users engaging in a shared virtual experience. In addition to receiving game data, frontend 1710 may be configured to receive confidential health-related data via a Health Insurance Portability and Accountability Act (HIPAA) compliant health data tunnel such as a virtual private network (VPN), which health-related data may be passed to healthcare diagnostics and treatment module 1800 via a HIPAA-compliant security gateway 1810. In an alternate configuration, healthcare diagnostics and treatment module 1800 receives health-related data direct from game clients 1730 through a HIPAA-compliant health data tunnel such as a VPN via HIPAA-compliant security gateway 1810. In either configuration, the health-related data is secured against receipt by third parties.
Backend services 1720 interface only with frontend services 1710 and are not directly accessible by game clients 1730. Backend services 1720 provide the storage and administrative functionality for the game and comprise an analytics stack 1721 and a game database 1722.
Analytics stack 1721 allows for queries about game operations and statistics by gameplay programmers and designers, business managers, and customer service representatives. Game database 1722 stores all information about the game necessary for its operation including, but not limited to, locations, maps, activities of player characters and non-player characters, game states, and game events.
Game clients 1730 are software applications or web browsers operating on end-user computing devices which access cloud-based gaming platform 1700 to send and retrieve game-related data. Game clients 1700 may operate on any end-user device, three examples of which are smartphones 1731, personal computers (PCs) 1732, and gaming consoles or handheld devices 1733. Game clients 1730 access cloud-based gaming platform 1700 via a network connection (e.g., via the Internet or a local area network) exchange game-related data with frontend 1710 of cloud-based gaming platform 1700 and display the user's perspective of the game to the user of the device on which the game client is operating. Thus, each user sees a different perspective of the game from each other user. As will be further described below, in certain configurations this allows for a shared virtual experience or common activity along with a different gameplay feel or intensity and/or different brainwave entrainments for each user.
Healthcare diagnostics and treatment module 1800 comprises a HIPAA-compliant security gateway 1810, an artificial intelligence (AI) assisted healthcare diagnostics module 1820, and an alerts and treatments module 1830. In this embodiment, healthcare diagnostics and treatment module 1800 is shown as being located on a common platform. However, being a cloud-based system, a variety of network configurations may be used. The components of frontend 1710, backend 1720, and healthcare diagnostics and treatment module 1800 may be hosted on the same server, across a network of servers, or across a network of cloud-based services and microservices (Amazon Web Services (AWS)™ being one example of such a cloud-based service).
Healthcare diagnostics and treatment module 1800 receives a variety of health-related data such as dual-task data (data regarding physical and mental performance of a user while engaged in combinations of physical and mental activity), social game data (such as audio recordings or chat logs between players during gameplay), and certain types of game play data (including, for example, reaction times to events in the game). As will be described below, healthcare diagnostics and treatment module 1800 processes the received data through a variety of analyzers to make diagnostic predictions about the physical and mental health of the user. One or more trained machine learning algorithms may be used to identify patterns and correlations across disparate types of data to make predictions and diagnoses about the physical and mental health of the user.
AI-assisted healthcare diagnostics module 1820 receives and transmits data via a HIPAA-compliant security gateway 1810 which is configured to secure protected health information to, from, and within healthcare diagnostics and treatment module 1800 to prevent unauthorized access to protected health information of persons using the system. HIPAA-compliant security gateway 1810 uses information technology (IT) security best practices which include, but are not limited to, data encryption, access restrictions, permission controls, user authentications, and audit controls. HIPAA-compliant security gateway 1810 may use a HIPAA-compliant data health data tunnel 1702 which secures transmitted data end-to-end from game clients 1730 to healthcare diagnostics and treatment module 1800. HIPAA-compliant data health data tunnel 1702 may, as one example, use a virtual private network (VPN) established between game clients 1730 and healthcare diagnostics and treatment module 1800, which may, depending on configuration, run through frontend 1710. HIPAA-compliant data health data tunnel 1702 may be a separate connection from the connections between game clients 1730 and frontend 1710 through which game data 1710 is transmitted, in which case game data 1710 may not need to be encrypted. In some embodiments, HIPAA-compliant data health data tunnel 1702 and game data 1701 may be the same connection, but with HIPAA-compliant data health data encrypted or otherwise secured within the connection. For simplicity, HIPAA-compliant data health data tunnel 1702 and game data 1701 connections are shown as being singular connections, but in practice those connections will be made separately to each individual game client.
Patient database 1821 stores all incoming and outgoing patient data including, but not limited to, health-related data, game data, and healthcare diagnoses. Healthcare related data may include patient data such as medical records, medical evaluations, diagnoses, physical and mental evaluations, and dual-task data comprising physical and mental data acquired during dual-task testing. Game data may include patient data acquired during game play or related to game play such as types of games played, game scores, time spent playing, in-game performance data such as reaction times to certain events, trends in gameplay such as improvements or degradation over time, and social game data such as audio recordings or chat logs between players during gameplay. Diagnoses may include any sort of evaluation and recommendation regarding physical function or mental function including both high and low functionality or ability such as evaluations of cognition, speech, auditory processing, vision processing, motor skills, emotions, and memory. Diagnoses may include, but are not limited to, diagnoses of medical conditions, suspicions or indications of disease, suspicions or indications of chronic physical conditions, suspicions or indications of chronic mental or neurological conditions, and recommendations for treatment, rehabilitation, or therapy of any of the above.
Physical function analysis module 1822 receives and analyzes data associated with a physical task of a dual-task functional analysis. This will typically be the primary task of a dual-task functional analysis. Physical function analysis module 1822 may be configured to evaluate a variety of aspects of a patient's physical function including, but not limited to, range of motion, movement profiles, and gait analysis, each of which is described in more detail herein below. Analyses produced by physical function analysis module 1822 are output to machine learning algorithm 1826 as data for inclusion in determination of diagnoses by machine learning algorithm 1826. Physical function analysis module 1822 and neurological function analysis module 1823 may coordinate with one another to act as a dual-task functional analysis system as further described herein below.
Neurological function analysis module 1823 receives and analyzes data associated with mental task of a dual-task functional analysis. This will typically be the associative activity task of a dual-task functional analysis. Neurological function analysis module 1823 may be configured to evaluate a variety of aspects of a patient's mental or neurological function including both high and low functionality or ability such as evaluations of cognition, speech, auditory processing, vision processing, motor skills, emotions, and memory, each of which is described in more detail herein below. Analyses produced by physical function analysis module 1822 are output to machine learning algorithm 1826 as data for inclusion in determination of diagnoses by machine learning algorithm 1826. Physical function analysis module 1822 and neurological function analysis module 1823 may coordinate with one another to act as a dual-task functional analysis system as further described herein below.
In-game performance analysis module 1824 receives and analyzes data associated with game play including, but not limited to, in-game performance data. In-game performance data may be separate from associative activity task data received by neurological function analysis module 1823, although there may be some overlap, depending on the game or software in operation. As a general rule, in-game performance data will be ancillary game play data such as shots per kill (in first person shooter games), number of tiles removed (in tile-based games like Mahjong), track records and lap times (in racing games), time spent playing each game, and similar data. This data may be tracked over time to identify deviances from expectation that may indicate some physical or cognitive change. For example, if a player plays a certain game on a daily basis, the player's in-game performance data would be expected to improve over time. A decrease in performance despite continued play, especially a sudden or dramatic decrease, may suggest a physical or neurological deficiency. Analyses produced by in-game performance analysis module 1824 are output to machine learning algorithm 1826 as data for inclusion in determination of diagnoses by machine learning algorithm 1826.
Mental health analysis module 1825 receives and analyzes game-related social data such as chat sessions, audio from team or group gameplay, lobby interactions, game-joining or partnering preferences and trends, game-related group activities, and membership in game-related clubs, factions, or guilds. Game-related social data may be separate from associative activity task data received by neurological function analysis module 1823, although there may be some overlap, depending on the game or software in operation. This data may be analyzed to identify potential mental health issues such as depression, anxiety, anger, sadness, frustration, and the like. One method of analysis that may be used by mental health analysis module 1825 to identify potential mental health issues is use of a trained machine learning algorithm to recognize patterns of social interaction similar to those that have led to such issues in a larger group comprising the training data for the machine learning algorithm. For example, a trend in the player's social data toward the use of words and phrases like “tired,” “exhausted,” “lack of energy,” in chats and audio with friends and teammates, combined with a withdrawal from or reduced activity in group activities, may suggest that the player is suffering from depression. A machine learning algorithm trained on a large database of similar social data and associated mental health issues would be able to recognize complex patterns in the social data suggestive of various mental health issues. Analyses produced by mental health analysis module 1825 are output to machine learning algorithm 1826 as data for inclusion in determination of diagnoses by machine learning algorithm 1826.
Machine learning algorithm 1826 is one or more machine learning algorithms configured to identify patterns in data. Machine learning algorithm 1826 is configured to make health-related diagnoses by identifying patterns in complex data. Machine learning algorithm 1825 may receive either data input to the various modules 1822-1825, or the outputs of the various modules 1822-1825, or a combination of the two. Based on this complex data set comprising many factors associated with a person's physical function and mental function as described above for the various modules 1822-1825, machine learning algorithm 1826 makes one or more diagnoses regarding one or more aspects of the person's physical or mental function. Diagnoses may include any sort of evaluation and recommendation regarding physical function or mental function including both high and low functionality or ability such as evaluations of cognition, speech, auditory processing, vision processing, motor skills, emotions, and memory. Diagnoses may include, but are not limited to, diagnoses of medical conditions, suspicions or indications of disease, suspicions or indications of chronic physical conditions, suspicions or indications of chronic mental or neurological conditions, and recommendations for treatment, rehabilitation, or therapy of any of the above. Diagnoses may be combined into a composite functioning score spatial map showing ability in a plurality of functional areas, as further described below.
Machine learning algorithms excel at finding patterns in complex data or exploring the outcomes of large numbers of potential options. There are three primary categories of machine learning algorithms, supervised machine learning algorithms, unsupervised machine learning algorithms, and reinforcement machine learning algorithms. Supervised machine learning algorithms are trained to recognize patterns by training them with labeled training data. For example, a supervised machine learning algorithm may be fed pictures of oranges with the label “orange” and pictures of basketballs with the label basketball. The supervised machine learning algorithm will identify similarities (e.g., orange color, round shape, bumpy surface texture) and differences (e.g., black lines on basketball, regular dot pattern texture on basketball versus random texture on oranges) among the pictures to teach itself how to properly classify unlabeled pictures input after training. An unsupervised machine learning algorithm learns from the data itself by association, clustering, or dimensionality reduction, rather than having been pre-trained to discriminate between labeled input data. Unsupervised machine learning algorithms are ideal for identifying previously-unknown patterns within data. Reinforcement machine learning algorithms learn from repeated iterations of outcomes based on probabilities with successful outcomes being rewarded. Reinforcement machine learning algorithms are ideal for exploring large number of possible outcomes such as possible outcomes from different moves on a chess board. Within each primary category of machine learning algorithms, there are many different types or implementations of such algorithms (e.g., a non-exhaustive list of unsupervised machine learning algorithms includes k-means clustering algorithms, hierarchical clustering algorithms, anomaly detection algorithms, principle component analysis algorithms, and neural networks. The category and type of machine learning algorithm chosen will depend on many factors such as the type of problem to be solved (e.g., classification of objects versus exploration of possible outcomes), the need for insight into how the machine learning algorithm is making its decisions (most machine learning algorithms operate as black boxes wherein their decision-making is opaque to users), accuracy required of predictions, availability of labeled training data sets, and knowledge or lack of knowledge regarding patterns or expected patterns within the data.
Alerts and treatments module 1830 receives and transmits data via a HIPAA-compliant security gateway 1810 which is configured to secure protected health information to, from, and within healthcare diagnostics and treatment module 1800 to prevent unauthorized access to protected health information of persons using the system. HIPAA-compliant security gateway 1810 uses information technology (IT) security best practices which include, but are not limited to, data encryption, access restrictions, permission controls, user authentications, and audit controls. HIPAA-compliant security gateway 1810 may use a HIPAA-compliant data health data tunnel 1702 which secures transmitted data end-to-end from game clients 1730 to healthcare diagnostics and treatment module 1800. HIPAA-compliant data health data tunnel 1702 may, as one example, use a virtual private network (VPN) established between game clients 1730 and healthcare diagnostics and treatment module 1800, which may, depending on configuration, run through frontend 1710. HIPAA-compliant data health data tunnel 1702 may be a separate connection from the connections between game clients 1730 and frontend 1710 through which game data 1710 is transmitted, in which case game data 1710 may not need to be encrypted. In some embodiments, HIPAA-compliant data health data tunnel 1702 and game data 1701 may be the same connection, but with HIPAA-compliant data health data encrypted or otherwise secured within the connection. For simplicity, HIPAA-compliant data health data tunnel 1702 and game data 1701 connections are shown as being singular connections, but in practice those connections will be made separately to each individual game client.
Patient database 1821 stores all incoming and outgoing patient data including, but not limited to, health-related data, game data, and healthcare diagnoses. Healthcare related data may include patient data such as medical records, medical evaluations, diagnoses, physical and mental evaluations, and dual-task data comprising physical and mental data acquired during dual-task testing. Game data may include patient data acquired during game play or related to game play such as types of games played, game scores, time spent playing, in-game performance data such as reaction times to certain events, trends in gameplay such as improvements or degradation over time, and social game data such as audio recordings or chat logs between players during gameplay. Diagnoses may include any sort of evaluation and recommendation regarding physical function or mental function including both high and low functionality or ability such as evaluations of cognition, speech, auditory processing, vision processing, motor skills, emotions, and memory. Diagnoses may include, but are not limited to, diagnoses of medical conditions, suspicions or indications of disease, suspicions or indications of chronic physical conditions, suspicions or indications of chronic mental or neurological conditions, and recommendations for treatment, rehabilitation, or therapy of any of the above.
Brainwave entrainment manager 1831 functions in a manner similar to brainwave entrainment manager of other embodiments previously described (e.g., brainwave entrainment manager 200, brainwave entrainment manager 1313). Upon receipt of one or more diagnoses for a person, brainwave entrainment manager 1831 selects an appropriate brainwave entrainment routine, and passes the selection on to a treatment control signal generator 1835, which generates the appropriate game instructions or controls to implement the brainwave entrainment routine selected within a current or future game.
Alert generator 1832 generates alerts for a player based on lists or databases of diagnoses and information relevant thereto. Upon receipt of one or more diagnoses for a person, alert generator retrieves relevant information about the diagnoses from one or more lists or databases, identifies issues of concern associated with each diagnosis, and generates alerts based on rule sets. The issues of concern may be things such as health warnings, side effect warnings, medication interaction warnings, physical exertion warnings, and the like. The issue of concern may include thresholds for action or generation of alerts such as warnings not to exceed a certain heartrate or time of exercise.
While not show in this diagram, alert generator 1832 may further generate alerts based on data such as that described above is being received by the various modules 1822-1825 of AI-assisted healthcare diagnostics module 1820 (dual-task data, in-game performance data, game-related social data). For example, alert generator 1832 may receive real-time data regarding a person's posture and balance and generate immediate in-game or on-screen warnings of an imminent fall. Such real-time warnings of falls are particularly useful in certain circumstances such as use of exercise machines my elderly persons who may be prone to falls or by persons wearing virtual reality (VR) headgear who are unable to visually perceive the real-world environment in which they are gaming.
Alerts may be in-game alerts such as pop-up windows or text on the screen or flashing of the screen or elements on the screen in a particular color or pattern (e.g., three flashes of the full screen in red to indicate serious alerts or in yellow to indicate moderate alerts). Alerts may be outside-of-game alerts such as via text or email, warning or advising of concerns identified while gaming. Outside-of-game alerts are appropriate where immediate action does not need to be taken, but the person should be advised of some information or concern.
Physical activity routine generator 1833 receives diagnoses and selects appropriate physical exercise routines for the person diagnosed to perform based on known or suspected associations between physical exercise and the diagnosis. For example, walking is considered to be an effective form of physical rehabilitation for patients with various chronic conditions such as low back pain, strokes, and peripheral artery disease. Walking can be prescribed at various speeds and lengths of time and can be adjusted based on feedback either from the patient or from analyses from a dual-task functional analysis system comprising an exercise device and sensors for providing feedback from physical activity. Likewise, cardiovascular exercise such as running and cycling can be an effective form of medical treatment for chronic diseases such as obesity, high blood pressure, heart disease, and diabetes. It can be used preventatively to reduce the risk of other diseases such as thrombosis. Studies have also shown that cardiovascular exercise may be an effective treatment for neurological diseases such as Alzheimer's disease, age-related memory loss, and age-related dementia. Strength training such as weight lifting resistance-based exercise machines can prevent and treat muscle loss and bone density loss, particularly in elderly patients. Using databases of medical knowledge comprising known and suspected uses of physical activity to prevent and/or treat diseases and medical conditions, physical activity routine generator 1833 generates a physical activity routine appropriate to the received diagnosis, and passes the selection on to a treatment control signal generator 1835, which generates the appropriate game instructions or controls to implement the brainwave entrainment routine selected within a current or future game. In some embodiments, physical activity routine generator 1833 may be the primary task generator for a dual-task functional analysis system.
Mental activity routine generator 1834 receives diagnoses and selects appropriate mental activity routines for the person diagnosed to perform based on known or suspected associations between mental exercise and the diagnosis. Brain-training games such as memory games, reasoning games, math-related games, puzzles, concept-association games, knowledge games, and the like, have been shown to be an effective form of mental rehabilitation and treatment for patients with neurological conditions such as age-related dementia and rehabilitation from brain injuries incurred from accidents and strokes. Different types of brain games encourage thinking and engage different portions of the brain, so different brain games can be prescribed as part of a mental activity routine for targeting treatment of different types of brain injuries, different brain locations, or different types of brain deficiencies. Using databases of medical knowledge comprising known and suspected uses of brain games to prevent and/or treat diseases and medical conditions, mental activity routine generator 1834 generates a mental activity routine appropriate to the received diagnosis, and passes the selection on to a treatment control signal generator 1835, which generates the appropriate game instructions or controls to implement the brainwave entrainment routine selected within a current or future game. In some embodiments, mental activity routine generator 1834 may be the associative activity task generator for a dual-task functional analysis system.
The device of this embodiment is designed such that is can be mounted on an exercise machine (that may or may not be otherwise equipped for brainwave entrainment purposes), whereby it can be used to provide brainwave entrainment using virtual objects on the display 301, optionally with supplemental brainwave entrainment from the lights 302 and/or speakers 303. The use of virtual objects with brainwave entrainment allows for flexibility in applying brainwave entrainment. Brainwave entrainment using virtual objects provides essentially unlimited variability in terms of stimulator sizes, shapes, colors, movements, and allows for the use of multiple stimulators simultaneously, each with different characteristics. Further, gamification changes the brainwave stimulation from passive receipt of light therapy to active engagement with the visual stimulation objects, wherein the user's brain is actively stimulated during the activity, enhancing the effectiveness of the stimulation. Further, as the user is actively engaged with the virtual objects, stimulation can be applied based on where the user's attention is focused. Attention-based stimulation provides opportunities for both direct stimulation (e.g., flashing an object at which the user is looking) and indirect stimulation (e.g., flashing an object in the user's periphery of vision). For example, eye tracking technology can be used to determine where the user is looking on the screen at any given time, and objects at which the user is looking can be used to provide visual stimulation even if the user changes his or her attention to a different object on the screen. In this embodiment, an infrared emitter 304 emits an infrared light, which is reflected off the user's eye and cornea, and is received at an infrared-sensitive camera 305. The center of the eye is tracked in relation to a reflection from the cornea (the outer surface of the eye). The distance and direction of the difference between the center of the eye and the corneal reflection can be used to calculate the eye's position. Combined with a known distance to and size of the display 301 the location at which the user is looking can be determined. The user's attention to objects on the screen can be monitored over time to determine whether the user is remaining focused on the activity, or is getting tired and losing focus, and the determined level of user attention can be used to change the type, intensity, directness, and other characteristics of the stimulation.
Brainwave entrainment using virtual objects may be further enhanced by using multiple objects, each capable of providing complementary types of stimulation, and/or by intentionally directing the user's attention to objects providing certain types of stimulation. For example, if the user is playing a first person shooter (FPS) game that involves shooting attacking aliens, the user's attention will naturally be focused on finding attacking aliens, aiming at them, and shooting them. As each alien will be the focus of the user's attention sequentially, the alien at which the user is currently looking may be flashed at appropriate frequencies and in appropriate colors to provide appropriate brainwave stimulation. Simultaneously, other objects on the screen (or even the background) may be selected to provide a complementary visual stimulation in the periphery of the user's vision. Further, brainwave entrainment using virtual objects may be enhanced by selecting multiple treatment modalities (e.g., light, sound, vibration, electrical stimulation) applied either simultaneously or sequentially, by varying the frequency or frequencies of brainwave entrainment (e.g., from about 0.5 Hz to about 100 Hz), and by varying the intensity and/or scale of the treatment (e.g., from subtle, localized vibrational or electrical stimulation to area-wide, intense stimulation such as high-intensity room lighting and sound).
Application of brainwave entrainment using virtual objects and gamification allows for brainwave entrainment to target certain neurological functions by enhancing and concentrating the effect of the brainwave entrainment on the stimulated areas of the brain. As one example, a person with memory loss may be asked to play a memory-based card matching or tile matching game (mental activities which stimulate certain portions of the brain). While the person is engaged in the mental activity, brainwave entrainment is applied via the game objects on the display 301 and/or the lights 302 and/or speakers 303. As the neurological functions in the brain associated with memory are being stimulated, the neurons in the brain associated with those functions are in an already-stimulated state, and the brainwave entrainment's stimulation of oscillations in the electrochemical state of neurons in those already-stimulated areas will have a more pronounced effect than on other areas of the brain. In this way, the already-stimulated areas of the brain may experience a greater reduction in degenerative conditions (i.e., reductions in amyloid plaques and tau phosphorylation) and greater increases in synaptic density.
The stationary recumbent bicycle 410 comprises a base 415, a chair back 411, a seat 412, arm rests 414, a plurality of supports 413 connecting the chair back 411 and seat 412 to the base 415, a resistance mechanism 416 allowing for resistance to a pedaling motion of the user, and a pedal system 417 for the user to pedal in a cycling motion. The stationary recumbent bicycle 410 thus provides the means for the user to engage in a physical task in the case where dual task stimulation (and/or dual task assessment) is being applied.
The localized and/or individual stimulation transducers 420 of this embodiment are a headband 421 with vibratory stimulation and hand grips 422 which provide electrical stimulation. These provide localized stimulation which can only be perceived by the user, which also makes them individual stimulation transducers (as opposed to the other scales, which can be perceived by others, and which could be used to provide brainwave entrainment to more than one person using the same transducer(s)). The headband 421 may produce simple vibratory (i.e., tactile) stimulation to the head, or may be configured to produce vibrations at certain locations on the head and at certain intensities so as to be perceptible by the middle and inner ear, which causes the stimulation to be both tactile and auditory in nature. This double stimulation (tactile and auditory) amplifies the effect of a single type of transducer, increasing the efficiency of brainwave entrainment from applications of that transducer.
The small area stimulation transducers 430 of this embodiment are devices attached to the exercise machine 410, but not directly attached to or in contact with the user. For example, a console comprising a display 432, light bars 433, and speakers 434 similar to that of the device of
The large area stimulation transducers 440 of this embodiment are devices that can be used over a large area and potentially a large number of persons such as a room or auditorium. In this embodiment, The large area stimulation transducers are large LED light bars 442 and large speakers 443 attached to a wall 441 of the room in which the stimulation will be applied. The large area stimulators such as the LED light bars 442 and large speakers 443 on the wall 441 can be used to fully immerse the user in intense brainwave entrainment with large areas of bright light and loud, booming sounds. The immersion and intensity can be enhanced, for example, by surrounding the user with large area stimulators on walls on all sides (and possibly ceilings and floors) covering the user's entire visual area, so that the user receives visual stimulation no matter in which direction the user looks an auditory stimulation no matter where the user is located. Higher immersion and intensity may provide greater beneficial effects from brainwave entrainment.
It is important to note that any type of transducer can be applied at any scale. For example, light stimulation can be configured such that it is seen only by one person (e.g., in glasses or goggles), or is seen by a small number of persons (e.g., a single LED light bar), or is seen by many people (e.g. room lights, stadium lights, etc.). Further, the intensity of stimulation can be largely varied separately from the scale of stimulation. However, depending on the circumstances and application, brainwave entrainment at certain scales and/or intensities may be more useful or effective than at others.
The different scales of stimulation transducers allow for a choice of the level of immersion the user experiences with respect to the brainwave entrainment, and to some degree, the level of intensity of the brainwave entrainment. Immersion is the quality of being surrounded by or absorbed in an experience. Intensity is the magnitude of the experience. They are separate qualities (e.g., a localized electric stimulation can be intense, but not immersive), but there can be an increase in intensity with an increase in scale (for example, if light stimulation comes from all directions, it will tend to be both more immersive and more intense, although the intensity of the lights can be reduced to offset this tendency). For example, a localized, subtle electrical stimulation through electrically-conducting hand grips 422 provides minimal immersion of the user in the brainwave entrainment. This may be useful, for example, where intense concentration on the dual task stimulation is necessary. Small area stimulation transducers such as the LED light bars 433 on the screen console are useful for mid-level immersion and mid-level intensity of brainwave entrainment. The LED light bars 433 cover a small, but significant, area of the user's view, and the speakers 44 are large enough to provide a substantial auditory stimulus. The large area stimulators such as the LED light bars 442 and large speakers 443 on the wall 441 can be used to fully immerse the user in intense brainwave entrainment with large areas of bright light and loud, booming sounds. The immersion and intensity can be enhanced, for example, by surrounding the user with large area stimulators on walls on all sides (and possibly ceilings and floors) covering the user's entire visual area, so that the user receives visual stimulation no matter in which direction the user looks an auditory stimulation no matter where the user is located. Higher immersion and intensity may provide greater beneficial effects from brainwave entrainment.
Further, it is important to note that the modalities (types of stimulation), scales, and intensities allows for tremendous flexibility in selecting suitable therapies regimens for different situations. For high-immersion scenarios (e.g., maximum brainwave entrainment with fewer cognitive demands such as listening to music), multiple modalities, scales, and intensities may be used at the same time. For example, while a user is listening to classical music, localized electrical stimulation may be applied to the wrist, small area visual stimulation may be applied using a single LED light bar, and large area tactile stimulation may be applied using subwoofers which produce sounds (infrasounds) which are inaudible to the human ear but can be perceived through the sense of touch (e.g., as oscillating pressure on the torso).
Further, modalities can be chosen to either amplify certain tasks or activities or to supplement them. For amplification, treatment modalities are chosen to include those corresponding to a given task or activity in gamification. As an example, if a user is assigned a game activity wherein the user must follow a moving object on the display with his or her eyes, the object can be flashed at 40 Hz for gamma entrainment therapy. As the user is already focused on the object, the user is focusing more intensely on visual activities (and the brain areas and functions associated with visual activities are stimulated), enhancing the effect of the visual gamma entrainment modality. For supplementation, treatment modalities are chosen to exclude those corresponding to a gamification task. As an example, if game activity assigned to a user is identifying songbirds presented on the display, flashing the birds at 40 Hz (or otherwise changing their colors or visual appearance) may interfere with the identification process. In such circumstances, a non-conflicting modality may be chosen such as flashing of background objects or supplementation with audible entrainment.
A suitable VR application or other gamification application is then chosen 502, which ideally should be consistent in content with the nature of the therapy regimen chosen. For example, if the therapy regimen is a regimen for brainwave entrainment that emphasizes alpha wave stimulation to induce relaxation in an overstimulated user, a VR application might be chosen that involves causal cycling along a forest path. If a more stimulating therapy regimen is chosen, for example something involving intense concentration and gamma wave therapy, a first person shooter might be chosen.
Based on the therapy regimen and VR application chosen, an entrainment routine is selected 503. For example, if the therapy regimen specifies that the overall brainwave entrainment goal is relaxation, the entrainment routine selected 503 may use alpha wave entrainment as the primary entrainment therapy, and may choose to apply alpha wave entrainment to a background virtual object (e.g., the sky or trees in the background of the casual cycling along the forest path), as flashing of background objects will be less intrusive (and possibly more relaxing) to the user than flashing of objects to which the user's attention is directed (e.g., the path or direction of the virtual bicycle). Selection of the entrainment routine 503 may further involve selecting amplification or supplementation 504 as appropriate for the circumstances, choosing appropriate treatment modalities (e.g., light therapy, sound therapy, vibrational therapy, electrical therapy, or combinations of such modalities) either for amplification 505 (treatments including those corresponding to the tasks, activities, or neurological function) or for supplementation 506 (treatments including those corresponding to the tasks, activities, or neurological function), and selecting a stimulation scale and intensity 507 for each modality appropriate for the treatment goals. In this example, three modalities are shown with different scales and intensities, localized haptic stimulation at a light intensity 507a, large area visual stimulation at a moderate intensity 507b, and small area auditory stimulation at a moderately intense intensity 507c. Brainwave entrainment is then applied using the chosen regimen, providing targeted treatment of particular areas of the brain and/or particular neurological functions via stimulation of those areas or functions using dual task stimulation.
At this point, a camera may be used to track the user's eye movements 508 to determine where the user is looking on the screen at a given moment 509. Based on the above inputs, appropriate virtual objects are chosen to apply brainwave entrainment by modifying virtual objects on the screen 510, which modification may take any number of forms (e.g., objects may be flashed at specific frequencies, the color of objects may be changed at specific frequencies, the size of objects may be changed at specific frequencies, objects may be rotated at specific frequencies, etc.). Any change to a virtual object that is perceptible to a user and can be applied at a repeating frequency (i.e., oscillating frequency) may be used to apply brainwave entrainment. Brainwave entrainment is applied using the virtual objects, optionally supplemented with entrainment from external transducers 511.
Input from biometric feedback (e.g., the user's heart rate) is received 512 and evaluated to determine whether the selected entrainment routine is having the desired effect (e.g., a lowering heart rate may be used to infer relaxation), and to change the entrainment routine, accordingly 513. For example, a lowering heart rate during alpha wave entrainment would likely indicate relaxation, in which case the entrainment routine would remain unmodified, but a rising heart rate would likely indicate irritation, in which case the entrainment routine might be modified by reducing the entrainment to theta wave entrainment to further induce relaxation. The process of tracking the user's attention and applying appropriate modifications to brainwave entrainment is repeated from step 508 until the therapy session ends.
For example, when paired with a camera and eye-tracking software, the on-screen virtual objects 1020 might represent an eye muscle strengthening exercise combined with brainwave entrainment, wherein the user is asked to find a target on-screen virtual object with a particular shape and follow the shape with his or her eyes. At the same time the target virtual object may flash a particular color at a selected brainwave entrainment frequency, with the color changing as the user's eyes either follow the target on-screen virtual object or stray from it. The target on-screen virtual object may, for example, be a pleasant light-blue color while the user's eyes are following it, and change to a bright red to re-attract the user if the user's eyes start following a different on-screen element.
In this embodiment, a clip-on eye-tracking unit 1040 may be attached to the display 1010 using plastic (or other material) clips 1044. The clip-on eye-tracking unit 1040 comprises a housing 1041, an infrared emitter 1042 which emits an infrared light that is reflected off the user's eye and cornea, and is received at an infrared-sensitive camera 1043, and clips 1044 which may be used to attach the clip-on eye-tracking unit 1040 to a display 1010. The center of the eye is tracked in relation to a reflection from the cornea (the outer surface of the eye). The distance and direction of the difference between the center of the eye and the corneal reflection can be used to calculate the eye's position. Combined with a known distance to and size of the display 1010 the location at which the user is looking can be determined.
In another use case, the on-screen virtual objects 1020 may represent a puzzle or game, and the brainwave entrainment may be provided by simply flashing the screen background 1012 at a selected brainwave entrainment frequency.
This example may be extended to virtual reality applications, wherein brainwave entrainment is provided by flashing in-game elements within the virtual reality environment.
In some embodiments, virtual reality environments and games could be used to provide entrainment opposite of the common expectation. For example, in the calm room shown in
Other modalities of brainwave entrainment such as sound and haptic feedback may be applied simultaneously with the visual stimulation. As more fully described above, these other modalities may be applied using either the same or different brainwave entrainment frequencies. As a non-limiting example, when the user in the virtual reality environment shoots the alien 2111, not only might the impact 2123 provide visual brainwave entrainment, but an audible tone might be generated corresponding to the flashing or color changing of the impact 2123 at the same entrainment frequency, and haptic feedback in the form of vibration of a game controller might also be applied. In some applications, for example in virtual environments comprising a darkened environment, the visual stimulation may not be used, but the auditory and/or haptic stimulation modalities may continue to be applied.
In a first exemplary configuration, game client D 1510 accesses cloud-based gaming platform 1300, receives game data and entrainment instructions from platform brainwave entrainment manager 1313. Client D 1510 converts the entrainment instructions to entrainment signals for display of virtual objects within the game world and displays them to user D as user D's perspective of the game world (or virtual experience). No feedback is provided, and it is simply assumed that user D is receiving the brainwave entrainment displayed.
In second exemplary configuration, game client E 1520 accesses cloud-based gaming platform 1300, receives game data and entrainment instructions from platform brainwave entrainment manager 1313. Client E 1520 converts the entrainment instructions to entrainment signals for display of virtual objects within the game world and displays them to user E 1521 as user E's 1521 perspective of the game world (or virtual experience). In this case, however, user E 1521 is wearing an electroencephalograph (EEG) device comprising a plurality of electrical sensors 1522 distributed about the head of user E 1521. The electrical sensors 1522 capture electrical signals produced by brain activity in certain locations of user E's 1521 brain, which act as a form of feedback as to the effect of brainwave entrainment on user E (i.e., brainwave entrainment is intended to impact certain brainwaves and (EEG signals are a direct measurement of electrical activity in the brain including brainwaves being produced by the brain). The EEG feedback is received by game client E 1520 which forwards it to platform brainwave entrainment manager 1313 for analysis and possible adjustment of brainwave entrainment instructions.
In third exemplary configuration, game client F 1530 accesses cloud-based gaming platform 1300, and receives game data only from cloud-based gaming platform 1300. Client E 1520 sends the game data to a client F brainwave entrainment manager 1533 operating on the same end-user device on which client F 1530 is operating. client F brainwave entrainment manager 1533 provides brainwave entrainment instructions to client F 1530, which converts the entrainment instructions to entrainment signals for display of virtual objects within the game world and displays them to user F 1531 as user F's 1531 perspective of the game world (or virtual experience). In this case, user F 1531 is wearing a heartrate monitor 1532 comprising a one or more electrical or optical sensors held in contact with the wrist or arm of user F 1531. The electrical sensors 1522 capture electrical signals produced by brain activity in certain locations of user E's 1521 brain, which act as a form of feedback as to the effect of brainwave entrainment on user E (heartrate signals are an indirect measurement the impact of brainwave entrainment on the user). The heartrate feedback is received by game client F 1530 which forwards it to on-board brainwave entrainment manager 1533 for analysis and possible adjustment of brainwave entrainment instructions.
Other configurations are possible, including combinations of the above configurations and different sensors and other means that may be used to obtain feedback such as blood pressure monitors, manual user feedback in the form of ratings of mood, etc.
In this example, two players are participating in the shared experience of a role-playing game, but have different sensitivities and brainwave entrainment goals. Player 1 wants a realistic experience, including depictions of realistic monsters, violence, and gore. Player 1 further wants excitement after a boring day at work, so is seeking brainwave entrainment that enhances his sense of danger. Thus, player 1's perspective 1610 shows a game world in which he is holding a realistically-rendered sword 1613, and facing a violent, realistically-rendered dragon 1612, with player 2 rendered in realistic armor 1611 to the dragon's right. The brainwave entrainment rendered in player 1's perspective 1610 may include pulsations, color changes, or movements of the dragon 1612 or other elements of the game world at frequencies intended to induce anxiety, stress, or danger.
Player 2 on the other hand is repelled by violence and gore, and uncomfortable with realistically rendered monsters. Player 2 wants to relax after a stressful day, and is seeking brainwave entrainment that instills a sense of calm. Player 2's perspective 1620, on the other hand, is a cartoonish rendering of the same scene, with the sword he is holding 1621 rendered in cartoon form, the dragon 1622 rendered as hapless and goofy, and player 1 rendered as a cartoon child 1623 to the dragon's left. The brainwave entrainment rendered in player 2's perspective 1610 may include pulsations, color changes, or movements of the dragon 1612 or other elements of the game world at frequencies intended to induce calm, relaxation, or contemplativeness.
This, while both players are engaging in a shared experience by playing the same role-playing game at the same time, the experience of each player will differ because of the differential rendering of the game world and differential brainwave entrainment of each player's perspective.
Additionally, a non-powered electric motor 2150 is mounted internal to the treadmill 2100 and the treadmill belt 2140 is connected to the motor 2150 drive shaft. Pressure sensors 2160a-n mounted under the belt 2140 provide a computer system the users weight in which the computer uses to vary the electrical resistance of the motor 2150 such that the physical resistance and upwards curvature 2131 of the belt 2150 gives the user an experience of simulated forward motion indistinguishable from actual forward motion. The amount of electrical resistance between the leads of the motor 2150 may be adjusted to vary the resistance provided to the belt by the motor. Initially, the resistance between the leads of the electric motor can be set to keep the belt 2140 from moving too easily but allows the user to start moving the belt under the same friction and force as would naturally be required walking off of the treadmill 2100. Furthermore, the calculated electrical resistance used by the computer system may be used as a zeroing point, or baseline, so that the back-electromotive force created by the users motion on the belt 2140 can be used as a varying voltage input to a computer system. In some embodiments, a powered electric motor can be used to the same effect.
The pressure sensors 2160a-n may further be used to capture to position of the feet on the belt 2140 by calculating the transverse and sagittal axis force vectors relative to each sensor 2160a-n against the user's total weight. In the same fashion, shifting of the user's body may also be obtained. The pressure sensors 2160a-n capture vertical motion as the user walks, runs, bobs, jumps, or squats by considering the displacement and velocity measured on individual pressure sensors 2160a-n rather than relative to the others. Combining these measurements, the characteristics of a user's gait (e.g., step frequency, step impact, weight distribution, etc.) may also be obtained for use in computer applications.
According to this embodiment, the torso and limbs harness 2110 has sensors 2170a-n proximal to the user connected to tethers 2180a-n and may comprise flex sensors, strain gauges, or other force sensors. Additional embedded components within the torso and limbs harness 2110 comprise input sensors such as accelerometers, gyroscopes, magnetometers, motion, touch, smart health devices, MEMS (micro-electromechanical system) devices, and location sensors. The sensors 2171 may also be output sensors such as vibration motors, fans, actuators, piezoelectric discs, and other output devices designed to stimulate or alert the user.
The torso harness 2110 may be fastened by a plurality of tethers 2180a-n. In one embodiment, elastic tethers 2180a-n may be designed for a specific range of motion bound by maximum and minimum elasticity regarding all three planes of motion. The elasticity limits may be designed for physical safety (i.e., stumble, trip, or fall protection) while wearing a VR headset or by individuals suffering from diminished motor control such as physical rehabilitation, recent surgeries, or age-related decline. The range of motion may also be limited by sensors 2170a-n connected to the proximal (or distal) ends such as strain sensors with a limited sheer strength or axis sensors with multi-planar limits. It should be appreciated that the designed elasticity of the tethers 2180a-n may be a balance of both safety and physical limitations.
In this embodiment, the height of the tethers and belt may be adjusted by placing a loop on the distal end of each tether on one of a series of hooks. Other means of adjusting the height of the tethers and belt may be used, for example, telescoping poles, sliding hooks, or pulleys attached at a relatively high point from which the belt may be lowered by adjusting the length of the tether (either manually or via motors).
According to an additional embodiment, fixed length straps may be used or a combination of fixed and elastic tethers, or straps or belts connected to actuators or motors operated by a computer which controls the travel distance of each tether 2180a-n accordingly. Combination fixed and elastic tethers may use either separate non-elastic tethers or integrated non-elastic tether components to place a hard limit on the stretch length of each tether, which can provide additional load bearing capabilities to catch a user during a fall. Any number of embodiments may be imagined by those skilled in the art.
Affixed to the front of the treadmill is a motion sensing input device 2190. In this embodiment, the motion sensing input device comprises RGB cameras, infrared projectors and detectors that map depth, and a microphone array, along with artificial intelligence software to allow the device to perform real-time gesture recognition, skeletal detection, and fine and gross motor movement detection. In other embodiments, the motion sensing device may be simpler in operation, such as an ultrasonic distance sensor. Simpler versions of the motion sensing input device 2190 can be used to determine the user's body position front to back on the treadmill, whereas more complicated motion sensing input devices 2190 can be used to identify different parts of the body and their relative positions and directions (e.g., arms, legs, torso and limbs, head, etc.), as well as being combined with other sensors to confirm such actions as jumping and twisting motions. Another example is a sensor device that inserts into a user's shoe that can supplement additional details for gait analysis and a balance profile.
The treadmill 2100 comprising the self-propelled and variable-resistive belt 2140, motion sensing input device 2170, pressure sensors 2160a-n, tethers 2180a-n, and various torso and limbs harness embodiments described in
Accelerometers, gyroscopes, and/or magnetometers in the torso and limbs harness 2221 may be used to determine the harness's position by taking the second time derivative from the accelerometer readings. Twisting by the user in the harness 2221 may be measured and displayed 2222, 2223 by taking readings from the gyroscope and magnetometer, rotary encoders, or a combination of sensors given that linear velocity is equivalent to angular velocity multiplied by position. The amount of twist may be displayed by a gradient bar representing the typical limits of human contortion at the hips, or by any other metric desired by the user. In this example, the user has twisted to the left 2224 approximately one-quarter of the typical limit. Also, in this example, the user is forward and left from center 2225. In other embodiments, the camera 490 may be used in conjunction with markers on the torso and limbs harness to track movement (e.g., small colored balls could be attached to the harness and tracked by the camera 490).
Gross motor movements 2230 may be captured by a motion sensing device coupled with data from the sensors on the proximal and/or distal ends of the tethers and data from input sensors in the harness itself. A computer system may use the combination of data to position the user in a virtual environment, display the user's range of motion to a telehealth professional, or monitor the user's form during an exercise routine activating a vibrating motor if the user needs to correct their form.
Other positional data may be obtained and displayed via the plurality of sensors such as the harness's position 2241 relative to the resting or calibrated baseline position 2242. Data from the Y-Z harness position 2240 can detect jumps 2243 or squats 2244 by formulating thresholds of position and may further be verified or supplemented by the gross motor movements 2230 data and X-Y positional data 2220. In this example, the tilt of the harness is measured and displayed 2245 as the user squats meanwhile the harness position 2241 crosses the squat threshold 2244 indicating the user has in fact performed a squat.
In this example, there are seven groups of composite functioning scores, each representing either a physical ability, a mental ability, or a combined ability, and all of which together represent a picture of an individual's nervous system function. The memory 2301 and cognition 2302 composite functioning score groups represent purely mental activities, and present a picture of the individual's ability to think clearly. The speech 2303, auditory 2304, and vision 2305 composite functioning score groups represent combined physical/mental activities, as each represents some physical/mental interaction on the part of the individual. For example, speech requires the individual not only to mentally generate words and phrases on a mental level, but also to produce those words and phrases physically using the mouth and vocal cords. It is quite possible, for example, that the individual is able to think of the words, but not produce them, which represents one type of neurological condition. The speech 2303 composite functioning score group represents that combined ability, and the auditory 2304 and vision 2305 composite functioning score groups represent a similar combined ability. The motor skills 2306 composite functioning score group represents a mostly-physical ability to move, balance, touch, hold objects, or engage in other non-cognitive activities (recognizing, of course, that the nervous system controls those movements, but is not engaged in higher-level thinking). The emotional biomarker 2307 group represents the individual's emotional responses to certain stimuli during testing, as would be indicated by lack of empathetic responses to virtual reality characters in a story, responses indicating sadness or depression, etc.
From the data obtained from other components of the system, a profile of an individual's functional ability may be created and displayed on the composite functioning score spatial map. For example, a baseline profile 2308 may be established for an individual during the initial use or uses of the system (e.g., pre-treatment evaluation(s)), showing a certain level of ability for certain composite functioning scores. In the baseline profile 2308 example, all composite functioning scores indicate significant impairment relative to the population average 2311, but the composite functioning scores for cognition 2302 and auditory 2304 ability are relatively stronger than the composite functioning scores for memory 2301, speech 2303, vision 2305, and motor skills 2306, and the emotional biomarker group 2307 indicates substantial impairment relative to the population average 2311. Importantly, changes in the profile can show improvements or regressions in functionality, and changes over time in the profile can be tracked to show trends in improvement or regression. For example, a later profile 2309 for the same individual shows improvement in all biomarker groups, with substantial improvement in the cognition 2302, auditory 2304, motor skill 2306 biomarker groups, and dramatic improvement in the emotion 2307 composite functioning score groups, relative to the baseline profile 2308. The biomarker group for emotion 2307 in the later profile 2309 shows performance matching or nearly matching that of the population average 2311.
The physical activity data capture device 2510 may be any type of device that captures data regarding the physical movements and activity of a user. In some embodiments, the physical activity data capture device 2510 may be a stand-alone device not associated with the activity being performed (e.g. a camera, ultrasonic distance sensor, heat sensor, pedometer, or other device not integrated into exercise equipment). In other embodiments, the physical activity data capture device 2510 may be exercise equipment or peripherals that captures motion and activity information of a user engaged in physical activity while using the device. For example, the physical activity data capture device 2510 may be in the form of exercise equipment such as stand-on or ride-on exercise machines like treadmills, stair stepping machines, stationary bicycles, rowing machines, and weight-lifting or resistance devices, or may be other equipment wherein the user stands separately from the equipment and pulls or pushes on ropes, chains, resistance bands, bars, and levers. The physical activity data capture device 2510 may be in the form of computer peripherals (e.g., game controllers, virtual reality headsets, etc.) that capture data while the user is performing physical movements related to a game or virtual reality environment, or exercise equipment that engage the user in physical activity, such as barbells, free weights, etc., which are configured to provide location and/or motion information such an integrated motion sensors or external cameras configured to detect the peripheral. The physical activity data capture device 2510 may be in the form of exercise equipment or peripherals and may be referred to as an exercise device. Sensors in the physical activity data capture device 2510 may be either analog 2511 or digital 2512. Non-limiting examples of analog sensors 2511 are motor voltages and currents, resistors, potentiometers, thermistors, light sensors, and other devices that produce an analog voltages or currents. Most digital sensors are analog sensors 2511 with integrated analog-to-digital converters which output a digital signal, although some sensors are digital in the sense that they measure only discrete steps (e.g., an on/off switch). In most cases, signals from analog sensors 2511 will be converted to digital signals using an analog to digital converter 2501. For signals from digital sensors 2512, conversion is not necessary. In some cases, signals may need to be calibrated by a sensor calibrator, which corrects for sensor drift, out of range errors, etc., by comparing signals to known good values or to other devices.
The software application 2520 is any software designed to assign primary tasks and associative activities, to engage the user in the primary tasks and associative activities, and track and store data from primary tasks and responses to associative activities. The software application 2520 may have, or may use or access, a number of different software components such as a virtual reality game or environment generator 2521, an associative activity manager 2522 which designs, selects, and/or implements testing protocols based on the user's profile. Many different configurations of the software are possible. The software application 2520 may be configured to present tasks to the user independent of inputs from the physical activity data capture device 2510, such as performing playing games, performing math computations, remembering where certain symbols are located, visually following an object on a screen, or reading and speaking a given text. Alternatively, the software application 2520 may be configured to engage the user in mental or combined activities that correspond in some way to the inputs from the physical activity data capture device 2510. For example, the user might be running on a treadmill, and the speed of the treadmill might be used as an input to a virtual reality environment which shows the user virtually running at a rate corresponding to the rate of the real world treadmill speed. The software application 2520 is configured to record data regarding, or evaluate and assign scores or values to, the user's responses and reactions to the tasks presented by the software application 2520. For example, if the user is assigned the task of performing a mathematical calculation, the correctness of the user's response may be evaluated, scored, and recorded as data. As another example, the user may be presented with the task of speeding up or slowing down a running motion in response to a visual cue, and the speed of the user's reaction may be recorded as data. In such cases, a data integrator 2530 may be used to integrate the data from the physical activity data capture device 2510 with the data from the software application 2520. In some embodiments, the data from the physical activity data capture device 2510 may be used to change the operation of the software application 2520, and vice versa (i.e., the software application 2520 may also be used change the operation of the exercise equipment, for example, providing additional resistance or speeding up the operation of a treadmill). In some embodiments, the data integrator may not be a separate component, and its functionality may be incorporated into other components, such as the software application 2520.
In some embodiments, the software application 2520, another machine-learning based software application such as a task assignment software application (not shown), may be configured to assign physical tasks to the user to be performed in conjunction with the associative activities assigned. Rather than simply performing continuously performing physical activity and recording the impact on the primary task of performance of the associative activities, the user may be assigned discrete physical tasks to perform while a mental activity is being performed. For example, the user may be assigned the physical task of pointing to a fixed spot on a display screen while reading aloud a text, and the steadiness of the user's pointing may be measured before, during, and after the reading, thus indicating an impact on the user's physical activity of the mental effort. Such dual-task testing may allow for more precise measurement and evaluation of relative functioning as different combinations of primary and associative activities are evaluated together. In some embodiments, the associative activity may be a second physical task or activity assigned to be performed simultaneously with a primary physical task or activity. Note that the terms “task” and “activity” as used herein are interchangeable, although the phrases “primary task” and “associative activity” are often used for purposes of clarity and convenience.
Many different aspects of movement and performance may be analyzed by the movement and performance profile analyzer 2700 through one or more of its many component analyzers 2701a-n such as the gait analyzer, balance analyzer, gross motor analyzer, fine motor analyzer, depth perception analyzer, executive function analyzer, visual function analyzer, auditory function analyzer, memory function analyzer, emotional response analyzer, etc. For example, the gait analyzer of the component analyzers 2701 ingests sensor data related to an individual's ambulatory movements (walking or running) while performing the given associative activity, and calculates a step frequency, step symmetry, weight distribution, and other metrics related to an individual's gait. These calculations are then compared to expected calculations for an individual without performing the given the associative activity. If an individual exhibits a limp while performing the given associative activity (e.g., popping virtual balloons), the step frequency, step symmetry, and weight distribution will all be skewed with the impaired side showing a shorter step duration and less weight applied. The expected calculations may be determined from the full range of sensor values, per-exercise calibrations, statistical data, or other means appropriate to the specific application. The balance analyzer of the component analyzer 2701 performs a similar function with respect to an individual's balance. Wobbling, hesitation, or partial falls and recoveries while performing a range of associative activities can be calculated from the data. The historical movement and performance comparator 2702 retrieves historical data for the individual (if such exists) from a user movement and performance historical data database 2710, and compares the current movement and performance data with historical data to determine trends in the movements and performances over time. The statistical movement and performance comparator 2703 retrieves statistical range of motion and performance data for populations similar to the individual from a demographic data database 2720, and compares movements and performances of the individual to similar individuals by sex, age, height, weight, health conditions, etc. The movement and performance profile generator 2705 takes the data from the prior components, and generates and stores a movement and performance profile for the individual which integrates these analyses into a comprehensive picture of the individual's movement and performance functionality.
