The present invention relates broadly to the field of brainwave-based technologies.
To date, the applications of the technology of electroencephalography (EEG) are limited and confined for use by only a specific group of users and is costly. It is desirable to make this technology readily available to general consumers for use in a wide range of applications that can be applied in daily lives.
Some existing indirect measurement methods of the actual brain emotional states are typically performed through facial emotion recognition techniques, electrical skin activity measurements and voice recognition approaches. However, such methods are only indirect and may thus not adequately represent the user's true brainwave state.
As a result, the utility of brainwave data has been under-utilized as a direct measurement of many physiological markers in the body which cannot be understood using indirect methodologies such as skin conductance for example.
Embodiments of the present invention provide a system, device and methods that seek to address at least one of the above problems.
In accordance with a first aspect of the present invention there is provided a system for measuring and processing brainwave data of a user, the system comprising one or more electrodes for measuring the brainwave data of the user, and a processing unit coupled to the electrodes and configured to process the brainwave data for determining a current mental state of the user and to generate, based on the current mental state of the user, a control signal for instructing activation of a means for manipulating the current mental state of the user.
In accordance with a second aspect of the present invention there is provided a method for measuring and processing brainwave data of a user, the method comprising providing one or more electrodes for measuring the brainwave data of the user, processing the brainwave data for determining a current mental state of the user; and generating, based on the current mental state of the user, a control signal for instructing activation of a means for manipulating the current mental state of the user.
In accordance with a third aspect of the present invention there is provided a device for measuring brainwave data of a user, the device comprising a portable instrument; and one or more electrodes disposed on, or for disposal on the portable instrument; wherein the portable instrument and/or the electrodes are configured for providing an adjustable configuration of the one or more electrodes for measurement of the brainwave data.
In accordance with a fourth aspect of the present invention there is provided a method for measuring brainwave data of a user, the device comprising providing a portable instrument; providing one or more electrodes disposed on, or for disposal on the portable instrument; and providing an adjustable configuration of the one or more electrodes for measurement of the brainwave data.
Embodiments of the invention will be better understood and readily apparent to one of ordinary skill in the art from the following written description, by way of example only, and in conjunction with the drawings, in which:
Embodiments of the present invention relate to the detection and processing and/or display of brainwaves, and utilizing the brainwave data for a variety of different applications with the aim of improving performance, quality of life and/or healthcare.
A system according to example embodiment comprises of a brainwave-sensing device and associated brainwave detection-interpretation software. Active interventions for manipulating a current mental state of the user can be built-in or external to the device. In different embodiments, the device can be implemented without provision of any interventions. The brainwave-sensing device, a lightweight and portable instrument, will for example be worn on a specific region of the head to track the brainwaves of the user, and is fitted with dry electrodes that provide improved user handling and comfort. The brainwave detection-interpretation device can be incorporated into mechanical structures, such as, but not limited to, furniture (e.g. chairs, sofas, bed/pillows, vehicle seats etc.), windows and walls, and/or can be incorporated with electronic devices, such as, but not limited to, a smartphone, tablet, laptop, desktop computer, phone, camera, or external instrument, which can be installed with the brainwave detection software to which the collected brainwave signals can be transmitted. The software processes the brainwave signals, for example to identify and display the brainwave states upon calibration of the user's basal brainwave states.
The utility of the detected and processed brainwave data can be broadly categorized into:
(1) communication (such as, but not limited to, social purposes),
(2) Health & wellness, including sports, medical-related purposes, and
(3) Products, services and entertainment (not limited to dining, gaming, movies, remote control gadgets/toys etc.)
Some examples of how the collected brainwave data can be used in example embodiments include, but are not limited to, centralized brainwave data compilation system, self-improvement, remote brainwave-detection and brainwave-sharing via digital platforms, brainwave-tagging of various digital media, brainwave-monitoring for social and healthcare reasons, brainwave-based rating of products and services, brainwave-targeted advertisements, brainwave-induced drug release, communication via brainwave-engagement with illness-stricken parties who are in comatose, stroke and/or unable to communicate or express themselves, as well as brainwave-modulated social robots. Further applications can include brainwave-controlled toys and assistive devices for general consumers and physically-disabled, sleep quality management for sports and wellness (including sleep apnea detection-intervention), brainwave-monitoring for both static and dynamic athletic tasks, and brainwave sensor-embedded headrests for drivers and passengers.
In one embodiment, a brainwave-sensing device is provided which allows for the detection and display of mental states such as emotions (happiness, anger, sadness, fear, excitement), pain, anxiety, sleep, mental fatigue, comfort and pleasure. The device can come in various forms and shapes, such as, but not limited to, a wearable device and can be a hand-held device depending on the application. In the description and claims, the term “portable” is used as including, at a minimum, a wearable device and a hand-held device. The form factor of the portable device can be further modified and/or customized in different embodiments to suit individual use-cases and/or personal preferences.
The portable device has at least one, and preferably multiple dry electrodes (and optionally other sensors or sensing devices) which can be configured in multiple ways to allow for different use cases. The software in example embodiments uses supervised/unsupervised algorithm(s) to detect the mental states, e.g. anxiety levels, of the user based on the brainwave data. A supervised approach requires the user to exhibit a specific mental state repeatedly so that the detected brainwave profile can be tagged to the desired mental state. An unsupervised approach uses a predetermined relationship between the specific mental state and the brainwave data, e.g. the brainwave profile, based on previously collected test data from a subject population. The mental state information can be stored on a centralized database for subsequent retrieval or analysis; and/or can be displayed on a computer system or mobile app.
Brainwave states such as, but not limited to, happiness, anger, sadness, pain, anxiety, fear and excitement play an important role in decision-making and planning of daily live. Different parts of the human brain are known to be responsible for specific functions of the human body, as described, for example, in Morris C G, Maisto A A. Psychology: An
Introduction, Eleventh Edition, 2001. For instance, attention is associated with the frontal brain areas, where children with Attention Deficit Hyperactivity Disorder (ADHD) tend to express abnormally high theta activation in the frontal brain areas, as described, for example, in Adam R Clarke, Robert J Barry, Rory McCarthy, Mark Selikowitz, Accepted: Aug. 9, 2001; DOI, http://dx.doi.org/10.1016/S1388-2457(01)00668-X; Brainwave memory is associated with the right brain area near the ear, as described, for example, in Edmonton Neurotherapy Brain Map, http://www.edmontonneurotherapy.com/Edmonton_Neurotherapy_QEEG_brain_mapping.h tm. Erk, S. et al. (2003) Brainwave context modulates subsequent memory effect. Neuroimage 18, 439-447 reported that subjects tend to exhibit activity in the right fusiform gyms and right amygdala when exposed to positive and negative emotional stimuli respectively.
Bekkedal M Y, Rossi J 3rd, Panksepp J. Human brain EEG indices of brainwaves: delineating responses to affective vocalizations by measuring frontal theta event-related synchronization. Neurosci Biobehav Rev. 2011 October; 35(9):1959-70 observed cortical regional differences in electroencephalography (EEG) alpha power shifts during brainwave stimulation, for example, left brain area activation with sad state, right brain area activation with angry state, and left and right brain area activations with happy state. The same study further reported that the greatest theta synchronization exists in the anterior hemisphere and can be gender-specific, such as male subjects responding with substantial theta power to sounds of pleasure and female subjects responding with high theta power to sounds of anger.
Pain and anxiety are known to associate with occipital lobe alpha power and frontal lobe alpha asymmetry respectively, as described, for example, in Nir R R, Sinai A, Raz E, Sprecher E, Yarnitsky D. Pain assessment by continuous EEG: association between subjective perception of tonic pain and peak frequency of alpha oscillations during stimulation and at rest. Brain Res. 2010 Jul 16;1344:77-86 and Briesemeister, B. B., Tamm, S., Heine, A., & Jacobs, A. M. (2013). Approach the good, withdraw from the bad—A review on frontal alpha asymmetry measures in applied psychological research, Psychology, 4(3A), 261-267.
Collectively, studies such as the abovementioned indicate the possibility of associating localized brainwave profiles with various brainwave states. Given an appropriate calibration procedure adapted from the prior literature on affective stimulation, for example Positive and Negative Affect Scale described in Schneider F, Gur R C, Gur RE, Muenz L R. Standardized mood induction with happy and sad facial expressions. Psychiatry Res. 1994 January; 51(1):19-31, International Affective Digitized Sounds described in Bradley, M. M., & Lang, P. J. (1999). International affective digitized sounds (IADS): Stimuli, instruction manual and affective ratings (Tech. Rep. No. B-2). Gainesville, Fla.: The Center for Research in Psychophysiology, University of Florida, or International Affective Picture System described in Lang, P. J., Bradley, M. M., & Cuthbert, B. N. (2005). International affective picture system (IAPS): Affective ratings of pictures and instruction manual. Technical Report A-6, University of Florida, Gainesville, Fla., it is advantageously possible to relate, for each individual subject, different localized brainwave profiles to specific levels of brainwave states.
The present specification also discloses apparatus for implementing or performing the operations of the methods. Such apparatus may be specially constructed for the required purposes, or may comprise a device selectively activated or reconfigured by a computer program stored in the device. Furthermore, one or more of the steps of the computer program may be performed in parallel rather than sequentially. Such a computer program may be stored on any computer readable medium. The computer readable medium may include storage devices such as magnetic or optical disks, memory chips, or other storage devices suitable for interfacing with a device. The computer readable medium may also include a hard-wired medium such as exemplified in the Internet system, or wireless medium such as exemplified in the GSM mobile telephone system. The computer program when loaded and executed on the device effectively results in an apparatus that implements the steps of the method.
The invention may also be implemented as hardware modules. More particular, in the hardware sense, a module is a functional hardware unit designed for use with other components or modules. For example, a module may be implemented using discrete electronic components, or it can form a portion of an entire electronic circuit such as an Application Specific Integrated Circuit (ASIC). Numerous other possibilities exist. Those skilled in the art will appreciate that the system can also be implemented as a combination of hardware and software modules.
By way of non-limiting example only, as electrodes 104 the available component g.Tec Dry g.SAHARAelectrode, 16 mm (https://www.olimex.com/products/eeg/openeeg/eeg-digital-pcb/) may be used, as amplifier 106 and signal filter 108 the available component Olimex EEG-Analog-ASM (https://www.olinex.com/produrts/eeg/openeeg/eeg-analog-pcb/) may be used, as the analog-to-digital converter 110 the available component Olimex EEG-Digital-ASM (https://www.olimex.com/products/eeg/openeeg/eeg-digital-pcb/) may be used, and as the transmitter 111 the available component SparkFun Bluetooth Mate Gold WRL-12580(https://www.sparkfun.com/products/12580) may be used.
A lightweight and portable instrument based on EEG technology can be provided as the brainwave detection device in example embodiments, whereby a single or multiple electrode(s) can be placed on a localized area of the head to detect specific brainwaves of interest of the user. This serves to detect brainwave status information such as, but not limited to, sleep, attention, happiness, anger, sadness, pain, anxiety, fear and excitement, where the electrode placement can be adjusted to suit detection of different brainwave states. For instance, the electrode(s) can be placed near the right ear to detect brainwave states such as joy and anger, or near the forehead to detect attention (Please provide full reference, as it was not in the list of references in the provisional application Clarke et al., 2001; Bekkedal M Y, Rossi J 3rd, Panksepp J. Human brain EEG indices of brainwaves: delineating responses to affective vocalizations by measuring frontal theta event-related synchronization. Neurosci Biobehav Rev. 2011 October; 35(9):1959-70). A reference electrode near the bony areas (e.g. ear bone) is typically used to act as a form of ground signal when amplifying the EEG electrode signal.
The brainwave detection device may be incorporated into mechanical structures such as, but not limited to, furniture (e.g. chairs, sofas, bed/pillows, vehicle seats etc.), windows and walls. In addition, it can be worn in various ways such as, but not limited to, either as a standalone measurement equipment designed in the form of ear hooks 250, earpiece 252 (such as hearing aids), spectacles 254, hairbands 256, hair clips 258, hair tie 260 (
With reference to
Based on the calibration, brainwave state identification can be obtained and the real-time brainwave state of users 800(1)-(N) can be detected and transmitted to a centralized receiving system 802 in example embodiments, as illustrated in
For example, in the data visualization step according one embodiment illustrated in
In example embodiments, the EEG-device can be integrated for use with external systems such as cameras e.g. 916 with video function, as illustrated in
For the upload/download step according to one embodiment illustrated in
Example embodiments also provide a sharing feature 1200, illustrated in
An online web store can be incorporated as part of the brainwave identification software or as a standalone web application in example embodiments, as illustrated in
The portable EEG device in example embodiments is preferably designed in such a way so as to ensure maximum comfort without compromising the signal quality of the brainwaves received from the brain. The form factor of the device can be modified and/or customized to suit individual use-cases and/or personal preferences. In the following, example design option for different embodiments will be described.
Single and Non-Modular Piece With a Fixed Structure
The portable EEG device can exist as a single and non-modular piece with a fixed structure—either in the form of wearables such as, but not limited to, headwear, forehead patch, accessories etc., or can exist in the form of a hand-held device for transient usage. The latter can come in a variety of shapes such as but not limited to a pistol-like design etc.
Collapsible Feature
Collapsibility of the portable EEG device allows the device to be folded into a smaller size without compromising structural integrity. Collapsibility may for example be provided, but is not limited to, having hinge joints e.g. 1500 between semi-flexible structures e.g. 1502 which, from a compact folded state, can be unfolded and affixed at the joints to fit comfortably against the head 1504 when in use, as illustrated in
Telescopic Design
A telescopic design of the portable EEG device can e.g. have sliding sections e.g. 1600, 1602 which can fit into each other. The sections 1600, 1602 of the device 1604 can slide so as to allow comfortable fitting on heads of all sizes as well as to allow compact storage of the device when not in use. The design, as shown in
Modular Design
The portable EEG device can comprise of multiple modules which can be disassembled, then refitted or combined with another module. This can come in the form of, but is not limited to, press-fit, lock-fit, hook-like type of individual modules e.g. 1700, 1702 that can be adjoined together to form the device 1704 and to create unique shapes and designs. Such a design preferably places no limitation on the variation of head sizes and allows disassembly for compact and easy storage.
Extendible/Attachment Design
The portable EEG device can have designs to allow for flexible placement of electrodes or other sensors. This preferably allows the addition of electrodes to the device to provide users with a broader range of brainwaves information at different parts of the brain; or the addition of sensors such as heart rate or temperature sensors for measurement of other physiological signals. This expands the scope of use of the device in its ability to correlating brainwave data with other vital signs.
The various device designs described above can exist individually or be combined with any of the various designs for different use-cases.
The portable EEG device in example embodiments comprises of dry conductive electrode(s). The device preferably has multiple electrodes which can be configured in multiple ways to allow for different use cases. The electrodes can be fixed as per an original or default position on the device, or can be adjusted and moved along the form factor of device, or removed from the original or default position and repositioned onto desired area(s) on the device. Additional electrodes can be placed onto desired areas on the device.
The electrodes used in example embodiments of the device are dry and ensures greater convenience which can be used directly without requiring application of gels onto the electrodes in order to provide a conductive medium for brainwave sensing. Such dry electrodes can preferably collect data independent of hair length and thickness and compensate for varying scalp conductance.
Flexible Placement of Electrodes
The electrode(s) can be placed anywhere along the portable EEG device in example embodiments to advantageously allow for collection of data from various parts of the scalp to allow for varied analysis. By allowing flexible placement of the electrode(s) for measurement of brain activity anywhere along the scalp, example embodiments can provide users with a variety of different brainwave information which can range from sleep tracking to anxiety monitoring to measurement of concentration levels.
Moreover, while most existing EEG devices have reference electrodes which are fixed, the portable EEG device in example embodiments allows the flexible placement of the reference electrodes. Preferably, the positions of the reference electrodes are symmetrical in nature.
There are several ways in which the electrodes can be attached to the portable EEG device in example embodiments. In one example, the electrodes are attached using holes e.g. 1800 or grooves 1802 located at suitable locations along the device to allow the electrodes to be fitted therein, as illustrated in
Similarly, the reference electrodes are preferably not fixed to a particular location on the head in example embodiments, and can be adjusted to match the use case, e.g. if the use case is focused on the left hemisphere, the reference electrodes can be shifted to the left side of the head to capture differences in brainwave signals between different regions of the left brain.
The electrical connections (e.g. wires) between the electrode(s) and the processing unit can be embedded within the form factor casing of the device 2100 in example embodiments, for example such that the electrode e.g. 2101 can slide and lock onto different slot locations e.g. while maintaining connections with the processing unit 2106 via extendable wires e.g. 2108, as illustrated in
The utility of brainwave data for various applications according to example embodiments has been broadly categorized into (a) communication (such as, but not limited to, social, healthcare, sports and medical purposes) (b) products, services and entertainment (such as, but not limited to, dining, gaming, movies, remote control gadgets/toys, driving etc.) and (c) rehabilitation. Some examples of how the collected brainwave data can be used include, but are not limited to, self-improvement, remote brainwave-detection and brainwave-sharing via digital platforms, brainwave-tagging of various digital media, centralized brainwave data compilation system, brainwave-monitoring for social and healthcare reasons, brainwave-based rating of products and services, brainwave-targeted advertisements, brainwave-induced drug release, communication via brainwave-engagement with illness-stricken parties who are in comatose/vegetative state, stroke and/or unable to communicate or express themselves, as well as brainwave-controlled social robots. Some example applications will now be described in detail as follows:
Brainwave-Detection and Monitoring
The complexity of human minds evolves from the paradigm of brainwaves and feelings and there could be useful data that we can potentially extract to be put to use for both personal and collective benefit. To understand how humans are affected by brainwaves, how the brainwave state can potentially impact on humans' lives and how to use brainwaves to value-add to daily live, example embodiments of the present invention allow for brainwave-detection and monitoring. This can be accompanied by the use of a system/a software such as, but not limited to, the systems/software described above, where the user's brainwave state can be tracked, recorded over a certain period of time, and compiled together as a graphical and/or statistical summary at the end of a specified duration (e.g. at the end of each week, month or year). This brainwave information can then be stored electronically and/or downloaded for other uses as described below:
(i) Brainwave-Detection and Monitoring For Self-Improvement
Example embodiments can be applied to serve as an assistive tool to help individuals be more aware and in control of their own brainwave states, acting as a self-check device to maintain a healthy state of mind. Sometimes, an individual does not pause to think and respond almost immediately to a particular behavior. Individuals may let their emotions overrun which in turn leads to regretful actions. This lack of awareness can often result in poor interpersonal relationships, misunderstandings and other associated problems such as depression. Example embodiments can provide self-therapy for maintenance of a healthy mind and well-being, hence maintaining a happier society on the larger scale.
The application (‘app’) or device in such embodiments displays the user's brainwave state and the user will be notified only when the brainwaves go beyond a certain emotional level that is calibrated as ‘healthy’. At this point, for example in state 2200 dominated by fear, the user 2202 will be given an option to activate a therapeutic audio-visual solution 2204, such as, but not limited to, music, images, readings, videos and games. The list of different therapeutic solutions can be personalized based on different brainwave states. For example, an angry person can be notified of his anger state, prompting him to play a self-healing soothing music for calming effect. A sad person would be prompted by a selection of funny videos to induce laughter. This methodology in example embodiments would be most useful when the person is constantly on the move. In addition, a computer-literate user can utilize the online software to customize advertisement pop-ups based on brainwave that is being expressed at that point of time. For example, when the computer-user feels stressed, he can pre-select from his list of favorite websites that can provide him instant relaxation. This application can be a potential tool that psychiatrists can recommend to their patients who suffer from some level of brainwave dysfunction such as depression and anxiety.
Example embodiments can also be applied towards anxiety sensing, particularly for, but not limited to, athletes, in which anxiety has been reported to influence athletic performance (Hann, Y. L. (2000). Brainwaves in sports. Champaign, Ill.: Human Kinetics). For instance, a wearable EEG device objectively detects the level of anxiety of the athlete in real-time, and the coach is then notified of the athlete's anxiety level. If the anxiety level is high, the coach can then make a decision to implement interventional measures (e.g. stretching exercises for athlete, pep talk etc.) to calm the athlete, prior to the commencement of the competition. The coach can subsequently check the athlete's anxiety level again to confirm that the athlete's anxiety level has dropped to an acceptable level for optimal performance in the competition. Apart from anxiety, example embodiments can be implemented for attention quantification during execution of certain maneuvers during static (e.g. air rifle) and dynamic (e.g. soccer and tennis etc.) sports, which would advantageously generate quantitative information for athletic performance management and optimization.
Sleep detection is another possible application of embodiments of the present invention, whereby the user 2300 can don a wearable EEG device 2302 during driving or an EEG device 2304 can be embedded into the user's headrest 2306, see
(ii) Brainwave-Detection and Monitoring For Healthcare
The applications of brainwave-detection and monitoring can be extended in example embodiments to healthcare and medical treatment, which is particularly useful for monitoring the mental states of people with brainwave irregularities, resulting in behavioral issues and challenges with interpersonal relationships. This brainwave information is most often important to, but is not limited to, parents, guardians, counselors, healthcare personnel or medical doctors to track the real-time brainwaves of their child, client and/or a group of people concurrently. For example, psychologists, counselors and psychiatrists could monitor their clients' disorder/condition (such as autism, bipolar disorder, ADHD etc.) in real time from their workplace, enabling tracking of the progressive condition of their client and to administer appropriate treatments to improve the patient's brainwave states.
This advantageously provides greater convenience and improved quality of treatment for their clients upon meeting. Parents or guardians could monitor their child more closely, who could be suffering from excessive stress levels or psychological trauma due to child abuse or bully by others; as well as elderly in the family who are struggling with managing ageing illnesses such as Alzheimer disease as well as the associated emotion-related issues. By remotely monitoring the brainwave states of these people in real-time, their mental health can be diagnosed beforehand, allowing others to empathize with their condition and provide adequate care for them. This application also has potential benefits especially in terms of emotional rehabilitation, for instance, helping prisoners rehabilitate through anger or violence management.
This application can be extended in example embodiments for use on a larger scale, for detecting and monitoring the brainwave states of patients in a center, hospital or institute. One such example is the mental institute, where a large group of mental patients with emotional dysfunctions need to be closely monitored. For this application, preferably all the brainwave data collected from the individuals (and their respective locations) can be channeled to a centralized receiving system of an example embodiment, such as described above with reference to
In addition, the application can be implemented in different embodiments for pain localization, as illustrated in
(iii) Alternative Form of Communication Via Brainwave-Detection and Monitoring
This application in example embodiments explores the potential of allowing people, who has limited ability to express themselves either through facial expressions, verbal and/or physical gestures (either due to, but not limited to, stroke, cerebral palsy and multiple sclerosis) to communicate with others through their brainwave signals that they express. This is particularly useful as an alternative form of communication for, but not limited to, the patient's family members as well as to the patients themselves in helping them to relieve their frustrations in not being able to communicate whilst people now can better empathize with their feelings and intentions.
Advantageously, this application can potentially help patients who are in a vegetative state regain consciousness earlier by identifying the most optimal form of stimulation through detection of a change in their brainwave state. For example, a common technique that family members would do for the vegetative patient is to provide stimulatory experiences of their senses that mimic an old memory. Family members of patients would now be able to know if the therapy is helpful based on a change in response of the patient. Rather than doing repetitive stimulation e.g. playing of a certain musical piece that they may not respond well with, experimentation with other forms of stimulation could possibly be more useful. This way, the brainwave state of a comatose patient may be tracked, displayed and reviewed over time by the family members to provide a form of two-way communication via brainwaves. The brainwave information can be potentially combined with electrocardiography (ECG) data to provide a better gauge of the response of the comatose patients, which may be triggered by family members' stimulatory methods. In addition, the EEG data can be directly fed to, for example, a forehead display 2600 on the patient 2602 (or another device such as a watch or handphone etc.), such that any EEG state (e.g. attentive, sleeping, in pain, happy) that is detected by the device can be immediately shown on the display, for example in the form of, but not limited to, words, graphical plots, numerals and emoticons, as illustrated in
Apart from communication, such embodiments could potentially aid in detective or police investigations especially when victims are traumatized and unable to communicate normally or the person under interrogation does not cooperate. In addition, this application is also not limited to only brainwave-detection and monitoring but can also be extended to assist in the rehabilitation of patients who have temporary loss of functionality in certain brain functions (e.g. speech, planning, memory and motor skills) due to diseases such as stroke, Alzheimer's disease and autism, whereby this application can be used as a form of assessment to evaluate the recovery of the patients. Such embodiments are not limited to the healthcare monitoring of brainwave states but can also be extended for use as devices for disease diagnosis (e.g. stroke, Alzheimer's disease, hypoglycemia, apnea) to facilitate prevention and treatment.
(iv) Brainwave-Detection and Monitoring For Societal or Global Issues
This application of brainwave-detection and monitoring in example embodiments can be implemented on a larger scale to obtain statistical data of a larger group of people, for the understanding of population-based behavior or issues and/or to help people make more informed choices. For instance, understanding the general brainwave state of a group of people in a discussion within one room, may help a person to decide whether to join the particular discussion group. As another example, Understanding the general brainwave state of the population residing in a country can more accurately measure the happiness index of a country, thereby aiding in the decision-making process of whether to migrate to the particular country.
Using brainwave-detection and monitoring could be performed with high accuracy in example embodiments by directly measuring the brainwaves of a large population of people with minimal disruption to the daily lives, where this information can then be collected and compiled through a centralized system. Other studies that require input on a nation/country and/or global level could also use embodiments of the invention for accurately tracking of the brainwaves of people, thereby unraveling important issues such as Gross National Happiness. Other possibilities of this application in example embodiments can range from location-based tracking of the brainwaves of different groups of people (indoor and outdoor monitoring), tracking happiness levels of citizens on a country and global level (rather than happiness index), to tracking attention levels of people in a class or conference session.
(v) Brainwave-Detection and Monitoring For Animals
The real-time brainwave monitoring of brainwaves can potentially be translated for use on animals. Notably, performing animals such as, but not limited to, horses trained for racing or shows need to be kept up to form for optimal performance. The utility of embodiments of the invention can come in handy as it serves as a predictor of performance level prior to the event, hence allowing the owner to strategize and/or prime the animal accordingly.
Brainwave-Sharing
The world is now easily connected by flights, where commute across the globe has become so easy and common. In addition, the world is becoming increasingly digitized with the rise of a digital media and technology that has brought about greater convenience in our daily lives allowing us to communicate with people remotely through a virtual platform. This application in example embodiments serves to further bridge this mode of distant communication, and to humanize digital interactions through our feelings and brainwaves, hence facilitating digital communication and making these interactions feel more like reality, particularly for people who desire more personal interaction with specific individuals on a regular basis but are limited geographically.
(i) Brainwave-Sharing Via Video or Voice Calls
Embodiments of the invention can be designed to improve relationships between specific individuals or groups of people by allowing their true emotions to be reflected during their virtual communications. This can be particular useful for, but is not limited to, those in long distance relationships relying on video or voice calls as their main mode of communication, as illustrated in
(ii) Brainwave-Sharing Via Short Text Messages
In addition, embodiments of the invention can be extended to group chats where a customized cluster of people, such as family or close friends are given the option to share and track one another's brainwaves via a platform 2800 that could allow simultaneous exchanges of short text messages through web or mobile communication systems, as illustrated in
(ii) Brainwave-Sharing Via Social Networking Platforms
The application of brainwave-sharing in example embodiments could be further applied to social networking platforms 2900 and through gaming interactions, where users are given the privacy option to upload and share their brainwaves, as illustrated in
(3) Brainwave-Based Rating
The brainwave information obtained from each individual can serve as an accurate form of rating for user satisfaction of a product and/or service in example embodiments. Such embodiments can be used in almost every industry where ratings are important for the company to improve their services/products based on the feedback and also to help general consumers to gauge and decide their preferred choice. Real-time or past brainwave-based ratings are applicable for evaluating the standards of an event such as educational talks, classes, exhibits. This rating approach can also be applicable for the rating of a teacher in order to identify how her training should be improved or for identifying top candidates or speakers for certain awards based on the audience's emotions; it can also be used to rate against someone (e.g. a celebrity's facebook page) to better assess his/her true popularity. This approach is not limited to brainwave-related ratings, but can also be leveraged on non-emotional information such as sleep, attention, learning and memory.
This approach of rating in example embodiments can be more useful for experiential-based experiences that involve brainwaves rather than based on an objective rationale, more commonly so when a service is involved. This experiential rating can be used to determine the true satisfaction level of customers as compared to the current system of objectively rating products/services on a numerical scale. Such as tool can help facilitate decision-making of the customers so as to provide them with maximal value and experience, as well as act as a feedback system for the company of interest to constantly seek to improve on their services/products. A centralized system where the brainwave information will be collated, calculated and displayed could be used for rating the individual branch outlets or averaged out as a collective representation of the company of interest. Example embodiments of this application can be widely used and implemented as a rating tool due to its accuracy based on customer satisfaction that it could potentially be used as a compulsory test for rating products and services under the International Organization for Standardization (ISO).
(i) Shopping Malls/Restaurants/Menu/Dishes
There is a wide range of choices one can make when it comes to a daily affair of dining and shopping. Example embodiments of the invention can expedite the decision-making process for customers during activities such as, but not limited to, dining and shopping. For instance, the directory 3000 of a shopping mall or supermarket would show the real-time average brainwave state of the customers in each store e.g. 3002, as illustrated in
(ii) Entertainment
Embodiments of the invention can be incorporated into 3D glasses or used as an independent device for movie-goers. The device 3200 can capture the movie goer's 3202 brainwaves throughout the course of the movie, see plot 3203, which would potentially serve as important feedback information for movie producers on the downsides and upsides of their movies and can also act as a form of rating to aid other movie-goers to decide which movies are worth watching, as illustrated in
(iii) Customer Service Support Experience
One usually has to visit the store directly or call up the customer support hotline, in order to obtain assistance for certain product or service. Embodiments of the invention can be incorporated into every store or even into every household landline as illustrated in
(4) Brainwave-Tagging For Personal and Security/Detective Use
Brainwave-tagging in example embodiments is a method in which the user's brainwaves can be captured and given the option to be reflected. Apart from visual capture of information through photo-taking, the brainwave states of the people being photographed may also be captured at the same time through the invention. Once the photo 3400 is uploaded, the brainwave states 3402, 3404 of the photographee can be displayed alongside or revealed upon clicking of a button or placing the mouse cursor over the photographee's face, as illustrated in
Brainwave-Induced Applications
Embodiments of the invention can leverage on the users' own brainwaves to run a certain useful application.
(i) Brainwave-Induced Advertising
Advertisers can categorize their product/services by having a particular brainwave state tagged to it according to example embodiments, allowing the product/service to pop up according to the user's brainwave state. This could be implemented in conjunction with the online web store as mentioned above. For example, a depressed person may trigger the display of an online advertisement offering psychological hotline assistance or even shopping therapy for an upset individual may be deemed helpful. In addition, a happy person may be prompted by celebratory advertisements that sell items which of great interest to him/her.
(ii) Brainwave-based Games
Games can be designed to incorporate the user's brainwaves in example embodiments, with the option to display, monitoring, share and also act as a feedback for controlling part-of or whole of the running of the game. This would humanize the game characters or activities, making it more interactive and realistic. Current games typically sense the physical movements to power the games, but using brainwaves with games to induce a certain function in example embodiments can help enhance the user's experience. For instance, a gamer who exhibits an excited brainwave state can trigger a special attack move for his character to defeat the opponent.
Brainwave-based games according to example embodiments could also be useful for the rehabilitation of people suffering from brainwave problems (e.g. depression), for instance, a smartphone game may require the user to be happy everyday in order for him/her to earn free daily virtual rewards (e.g. virtual coins) to help them proceed further in the game. This would encourage the user to maintain a happy state everyday and any progressive improvement in his/her mental states can be tracked over time using the aforementioned software. In addition, the brainwave information can also be used as a form of competing element in a game, whereby two or more people can compete to see who is the happiest, i.e. maintaining the highest happiness level for the longest time.
(iii) Drug Delivery Based on Brainwave Feedback
Embodiments of the invention can be part of a feedback system that receives brainwave information from the patient and determines whether the current brainwave state is below the desired ‘healthy threshold such as negative emotions, anxiety or pain. If the emotional state becomes negative, the system will trigger an implanted or external drug delivery device to release antidepressant or endorphins into the patients’ body, such that negative emotions can be relieved and a more positive emotional state can be attained.
(iv) Social Robots
(iv-i) Interaction With and Training
The utility of embodiments of the present invention can translate to the realm of social robots, where the detection of human brainwaves will be transmitted wireless to the robots. The robot can then sense the brainwave state of the user and provide suitable responses to improve the user's mood. This approach can help to create empathic robots which may be important in counseling depressed users. Example embodiments can also be used to refine and improve on certain activities performed by the robots until the human is satisfied with its performance. The emotional scale of both the human and the robot can be displayed and tracked before, during and after the activity to be performed. For example, the human feels disappointed or sad when the robot is unable to lift a 5 kg weight. The robot detects the undesired brainwave and tries harder to achieve better results. Upon repeated success, the robot succeeds and it exhibits facial happiness. Both the brainwaves of the human and the emotional scale of the robot can be displayed based on the task-specific activity. This could serve as a humanized-robotic model for various purposes including, but not limited to, parenting to demonstrate that growth and development is based on intrinsic motivation.
(iv-ii) Alternative-Communicator Using Robots as a Representative
For people who have difficulties in facial and verbal expression (e.g. comatose or multiple sclerosis patients), a robot representative can be used by the individual in replacement for his/her disability to expressing brainwaves through facial, verbal and physical methods, in example embodiments. This can become a communication tool to facilitate communication between people who are unable to talk or express themselves, where the brainwaves of the individual could be channeled wirelessly to the robot, who will express the respective brainwaves displayed with varying brainwave levels. The robot can then act as a communicator in person or on webcam for personal/distant communication through virtual video.
(v) Remote Control
The EEG device in example embodiments can be combined with positional sensors, such as the inertial measurement unit (IMU), to permit direction-targeted remote control of objects in a 3D environment. For example, an IMU-EEG integrated system can collect EEG data (e.g. attention) coupled with head orientation, such that an increased mental focus in a certain direction can be utilized to remotely perform certain tasks. For instance, an attachable actuator with embedded transceiver can be placed on a rocker switch, so that when the user gives a mental EEG command facing the actuator, the switch will be activated by the actuator and therefore lights up the bulb. Another example would be attachable wheels (with embedded transceiver) which can be placed under a toy car, so that when the user gives a mental EEG command facing the wheels, the toy car will move towards the user. Another possible use would be an attachable vibrating motor (with embedded transceiver) which can be placed onto a drinking cup, so that when the user gives a mental EEG command facing the vibrating motor, the cup vibrates. Potential users include general consumers (adults and children), and also patients with physical disability such as stroke-related paralysis, Parkinson's disease, muscle dystrophy, multiple sclerosis etc. In addition, the system can be modified for use in remote control of assistive devices, for example, a user with paraplegia dons the EEG device and is able to send EEG command, coupled with his/her head orientation, to control the direction of motion of the wheelchair.
In preferred embodiments, a system is provided that provides active intervention, upon detection of specific brainwave patterns. The active intervention can be by means of, but is not limited to, a mechanical stimulus/movement such as vibration or a sensory stimulus (temperature, prick), visual, auditory, olfactory stimulus.
The device in such embodiments can have additional attachments or embedded features such as but not limited to temperature-sensitive pads that can cause a change in temperature e.g. to decrease body temperature due to rising heat from anxiety via activation of the temperature-sensitive pads or activation of motor(s) for a mechanical stimulus.
The location of the stimulus can include, but is not limited to, the neck, temples, shoulder, back, back of ear, feet areas either individually or in combination.
The sensory stimulus may serve one or multiple interventions such as, but not limited to, massaging the temples to calm the user, poking in order to wake the user, regulating the body temperature and emitting lavender scent to provide mental relief.
The active intervention means can exist as part of the brainwave-sensing device in its entirety or can be integrated for use with independent therapeutic systems such as, but not limited to, a massage chair/hugging jacket etc.
Depending on the level of e.g. anxiety, the active system in such embodiment can be programmed to be activated accordingly, with relevant magnitude or frequency, to the preferred mode of intervention such as mechanical stimulus, the rhythm, intensity, massage duration.
Examples of embodiments in which the brainwave-sensing device exists independently of other systems such as a massage chair/vest that can be integrated for use together are illustrated in
In example embodiments such as, but not limited to, the example embodiments described with reference to
Depending on the level of the mental state detected, a corresponding set of motor vibrations, comprising of relevant features such as, but not limited to, magnitude or frequency, can be activated in example embodiments, as illustrated in
(1) Providing a brainwave-sensing device, including wearables such as headwear, forehead patch, accessories, but also hand-held equipment in a variety of different form factors such as, but not limited to, a pistol-like design
(2) Allows detection of mental states such as emotions (happiness, anger, sadness, fear, excitement), pain, anxiety, sleep, mental fatigue, comfort and pleasure, upon placement of electrodes against the user's head.
(3) The form factor of the device can be modified and/or customized to suit individual use-cases, applications or personal preferences. This may also allow comfortable fitting of the headband on heads of all sizes as well as to allow compact storage of the device when it is not in use.
(4) The device can have a modular design. For example, the wearable device in its entirety can comprise of multiple modules which can be disassembled, then refitted or combined with another module for different sizes, use-cases, aesthetics (shape/design) etc.
(5) The device can have a telescopic design. Telescopic mechanisms allow the sliding of sections which can fit into each other. The sections can slide so as to allow fitting on heads of all sizes and allow compact storage when not in use.
(6) The device can have an extendibility/attachment feature which allows additional electrodes/components such as, but not limited to, external sensors (heart rate monitor) to be added to the device. This allows monitoring of other useful information such as heart rate, temperature etc. for the individual applications of interest to supplement the brainwave information obtained.
(7) The device can have a collapsible structure. This allows the device to be folded into a smaller size without compromising structural integrity.
(8) Flexible placement of electrodes along the device. The device can have multiple electrodes which can be configured in multiple ways to allow for different use cases. Electrodes can be adjusted or removed from the original position and repositioned onto desired areas; additional electrodes and/or sensors can be added to the device.
Advantageously, the reference electrodes of the device are not restricted to placement on bony areas of the head and can be moved to more convenient locations. This allows user to place the electrodes on the appropriate locations to suit the different use-case or for the purpose of greater comfort without compromising accuracy of the system.
The addition of electrodes to the device can provide users with a broader range of brainwave information at different parts of the brain; or the addition of sensors such as heart rate or temperature sensors for measurement of other physiological signals. This expands the scope of use of the device in its ability to read brainwave data whilst correlating it with other vital signs.
(9) The device can have a design that allows electrodes/sensors to be attached in several different ways. For example, the device can have holes/grooves located on necessary locations to fit electrodes into the device; electrodes can be attached with conductive fasteners such as Velcro strips; electrodes can be magnetized with the device with opposite polarities. This allows easy relocation of electrodes or addition of electrodes/sensors to suit the different use-cases.
(10) The conductive electrodes used in example embodiments of the device can be dry electrodes. Dry electrodes can provide greater convenience and can be used directly without requiring application of gels onto the electrodes in order to provide a conductive medium for brainwave sensing. These dry electrodes can advantageously collect data independent of hair length and thickness and compensate for varying scalp conductance.
(11) An algorithm to identify the user's mental state and its associated levels in example embodiments can use a supervised approach that requires the user to exhibit a specific mental state repeatedly so that the detected brainwave profile can be tagged to the desired mental state. With increased repetition or training data, the computer action becomes tagged to the desired mental state. By way of non-limiting example only, reference is made to the supervised approach described in Empirical Evaluation of the Emotiv EPOC BCI Headset for the Detection of Mental Actions (http://pro.sagepub.com/content/56/1/193.abstract).
(12) The algorithm can allow unsupervised detection of mental states such as, but not limited to, anxiety levels., i.e. without requiring human input. This approach uses a predetermined relationship between the specific mental state and the brainwave profile, based on previously collected test data from a subject population. The algorithm can allow mental state identification, which can be especially useful for users who are unable to provide user input, e.g. vegetative patients, patients with mental disorders, elderly with dementia. The unsupervised approach allows healthcare workers to monitor the mental states, e.g. anxiety levels of a patient/trainee, which can aid in early intervention whenever necessary. Unsupervised algorithms rely on a pre-determined pattern (unsupervised), for example, but not limited to, attention detection, e.g. low amplitudes of alpha waves at the frontal cortex are scientifically reported to be associated with strong attention levels. Hence, if the EEG device detects low alpha amplitudes at the frontal cortex of the wearer, a corresponding high attention level can be notified by the device.
(13) The algorithm can also allow therapeutic interventions to be implemented such as playing calm music when it detects high anxiety as the users' mental state, etc. The algorithm can also be able to provide feedback to the user to help in reducing e.g. anxiety levels when high levels are detected.
(14) The algorithm used in example embodiments can preferably identify the mental state of the user and its associated levels, particularly patients and athletes, in an automated manner. The supervised approach allows for an adaptive user-specific mental state identification, based on regular user inputs. Over time, a significant amount of mental state data can be collected from a large user base, leading to a more robust identification algorithm.
(15) Example embodiments can provide a mobile app platform whereby the raw and/or processed brainwave (and/or other physiological) information can be transmitted to and displayed on the mobile phone for user to utilize in a convenient and meaningful manner.
Users are able to monitor and track their mental states at their convenience through a mobile app, and take the necessary preventive or interventive steps as required.
(16) The flexible placement of electrodes in example embodiments can allow easy relocation of electrodes along the device to suit the different use-cases. Hence one system can be suited to monitor multiple applications. Well-embedded less visible/non-visible electrodes may be better received by the public as a daily ‘cool’ wearable tool.
