Description

Head-mounted device and system for guiding brain waves and guiding method thereof

Technical Field

The present invention relates to the detection and guidance of brain waves, and more particularly, to a head-mounted device, a system and a method for guiding brain waves.

Background

Brain waves are electrical vibrations in the brain that result from the action of nerve cells. The electrical vibration in the brain varies with different states of the person, for example, when the person is awake or not awake, the vibration frequency varies differently, even when the person is open or closed.

Internationally, brain waves are divided into alpha, beta, delta, and theta waves according to different frequencies. In the non-concentration situation of human brain relaxation, alpha wave (8-12 Hz) is easy to exist; when the human brain is concentrated or under high stress, the brain is easy to be in beta wave (12-38 Hz); however, when the user goes to sleep, the radio waves of the human brain are converted into low frequency waves, such as θ waves (4 to 8 Hz) and δ waves (0.5 to 4 Hz), wherein the θ waves are classified as "subconscious waves" and the δ waves are classified as "unconscious waves".

Therefore, the brain wave state of the human body reflects the current performance of the human body, and if the brain of the human body can be guided appropriately, the brain of the human body can be assisted to enter the appropriate state, and a mental guiding selection can be provided. However, the measurement of brain waves is directed to electrical vibrations in the human brain, and it is necessary to perform measurement more accurately and also to take account of the wearing comfort of the subject. In addition, the electrical vibration characteristics of nerve cells in each human brain are different, and the guidance efficiency is the most important for the guidance effect.

Embodiments of the present invention relate to a head-mounted device, a system and a guiding method for guiding brain waves, which apply at least one of sound and light to generate a signal with stimulation, such as: the principle of human brain waves can be influenced by the sensory stimulation of light or/and sound, and the consciousness state of human brain waves tends to be influenced. The embodiments are described below with reference to the accompanying drawings.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram of a head-mounted device for guiding brain waves according to an embodiment of the present invention, and fig. 2 is a partial functional block diagram of the head-mounted device for guiding brain waves according to an embodiment of the present invention. In an embodiment, the head mounted device HD includes: a frame 10, an electroencephalogram detection module 20, an electroencephalogram guidance module 30, and a control module 50.

The control module 50 is coupled to the electroencephalogram detection module 20 to receive a first electroencephalogram signal S20. The control module 50 is coupled to the brain wave guiding module 30 for outputting a guiding stimulation signal S30 to control the brain wave guiding module 30, so that the brain wave guiding module 30 can provide signals with stimulation effect for the wearer, for example: sound, light or a combination of the two, wherein the sound or light can stimulate the sensory nerve of the wearer to generate perception.

The term "stimulus" as used herein refers to any signal that affects the sensory nerve, i.e., the sensory nerve produces a corresponding sensory effect, and does not mean a signal that is necessarily large to some extent. Embodiments of the present disclosure further apply to brainwave guidance, and thus the term "signals with stimulation" may include signals having a degree of correlation with the fluctuations of brainwaves. Fig. 2 illustrates the signal transmission process, but is not limited to transmitting only the first brain wave signal S20 or the guided stimulation signal S30.

The frame 10 shown in fig. 1 includes an eye-mask portion 11, a left ear portion 12A, and a right ear portion 12B. Both ends of the eye mask portion 11 are coupled to the left ear portion 12A and the right ear portion 12B, respectively. Other portions may also be provided between the eye mask portion 11 and the left and

right ears

12A and 12B to provide more functionality to the headset HD. The frame 10 is preferably a part or all of hardware (which may be a plastic material such as PC, ABS, and PC + ABS) that allows the eye portion 11 to be spaced from the wearer's eye when worn, without being attached to the wearer's face.

Frame 10 may provide for the configuration of the brain wave detection module 20, the brain wave guide module 30, and the control module 50. For example, the control module 50 can be a circuit board assembly disposed in the frame 10, and can integrate various functional modules, and can be used with a rechargeable battery and an integrated wireless communication module, so that the head-mounted device HD can be conveniently used and wirelessly connected to other devices.

The brain wave detection module 20 may include a plurality of sensing electrodes disposed on the frame 10, such as a first type brain wave detection element 21 disposed on the right ear 12B. An extended sensing electrode 211 may be disposed at the position of the right ear 12B by a pad 213, which may correspond to the right ear part of the wearer, and may simultaneously contact multiple parts of the ear of the wearer based on the feature of the extended length of the extended sensing electrode 211, such as: at least two of the Helix (Helix), anti-Helix (Anti-Helix), lobe (Lobull) and Tragus (Tragus) sites of the ear. The electrode can provide a larger sensing area for the ear, improve the accuracy of signal sensing, further provide the correctness of brain wave detection, contact with a larger area, reduce the contact pressure per unit area and further give consideration to the wearing comfort. In addition, when the head-mounted device HD is worn, the pad 213 can also provide a buffering function when the first brain wave detecting element 21 abuts against the ear, so as to improve the wearing comfort.

In the embodiment shown in fig. 1, the extended sensing electrode 211 can be extended and formed in a C shape on the pad 213, but is not limited thereto, wherein the C-shaped gap can be used for a portion corresponding to the tragus of the ear. The extended sensing electrode 211 can be made of a material capable of conducting an electrical signal, such as: stainless steel, or other metals, alloys, and even electrically conductive cloth, fibers, etc., but stainless steel has a low thermal conductivity and is more suitable for being worn in contact with the skin of the wearer.

In addition, a physiological signal measuring module 23 may be further disposed on the first type brain wave detecting element 21 near a position corresponding to the tragus adjacent to the ear. The physiological signal measuring module 23 may be fixed on the first type brain wave detecting assembly 21 by partially covering the pad 213 and exposed on the surface of the pad 213. Further, the physiological signal measuring module 23 can be disposed at the C-shaped notch adjacent to the extended sensing electrode 211, which can correspond to the tragus of the ear to measure the superficial temporal artery (arteriatemporal superior) near the tragus for providing the physiological data changes (such as pulse, body temperature, blood oxygen, heartbeat, etc.) of the wearer. The physiological signal measuring module 23 can be coupled to the control module 50, so that the head-mounted device HD can further provide more physiological data.

The physiological signal measuring module 23 may be an optical heartbeat measuring (PPG) device, for example, the physiological signal measuring module 23 has a light emitting unit and a light receiving unit, and the light receiving unit receives the reflected light and obtains the physiological parameter through the calculation of a built-in IC chip by the reflection of the skin of the wearer to the detection light emitted by the light emitting unit (diode).

The first type of electroencephalogram detection component 21 can be disposed on only a single ear (e.g. left ear or right ear), or can be disposed on both the left ear and the right ear, and only one of the electroencephalogram detection components needs to have the physiological signal measurement module 23, for example: the first type electroencephalogram detection component 21 disposed only on the right ear 12B is provided with the physiological signal measurement module 23.

As shown in fig. 1, the second type of electroencephalogram detection element 22 is matched with the first type of electroencephalogram detection element 21 to obtain electroencephalogram signals through different measurement points. The second type of brain wave detecting device 22 has a forehead pad 223, a forehead sensing electrode 221 is disposed on the forehead pad 223, and the forehead pad 223 is disposed on the eye mask portion 11 in a protruding manner. In addition, a groove is formed on the eye mask portion 11 and adjacent to the lower portion of the second-type brain wave detecting element 22, and a nose pad 225 made of an elastic material is disposed in the groove for abutting against the nose of the wearer. The widths of the forehead pad 223 and the forehead sensing electrode 221 are preferably both greater than 5cm, so as to increase the contact area between the forehead sensing electrode 221 and the forehead of the wearer, thereby ensuring the reliability and accuracy of measurement. On the other hand, in a situation where the first type of electroencephalogram detection element 21 is disposed on both the left ear and the right ear, the second type of electroencephalogram detection element 22 is further incorporated, so that the

sensing electrodes

211 and 221 form an electroencephalogram sensing loop with a pickup point, a grounding point, and a reference point.

The brainwave guide module 30 has at least one first type of brainwave guide element 310 and one second type of brainwave guide element 320. First type of brain wave guiding element 310 may be an acoustics unit disposed on the left ear 12A or the right ear 12B, such as the first type of brain wave guiding element 310 surrounded by the extended sensing electrode 211 shown in FIG. 1. The second-type brain wave guiding component 320 is at least one light emitting unit disposed on the eye cover portion 11. The second type of brain wave guide assembly 320 illustrated in fig. 1 has two light emitting units, which can be respectively used to correspond to two eyes of the wearer, and each light emitting unit can be, for example, a light emitting device with RGB three-color light emitting capability. By controlling the sound effect units corresponding to the two ears, a sound signal with frequency difference between the left ear and the right ear can be generated for the wearer to influence the brain wave of the wearer.

Next, please refer to fig. 3, which is a schematic diagram of a head-mounted device for guiding brain waves according to another embodiment of the present invention. The outer surface of the frame 10 may include a display unit 60 coupled to the control module 50. The control module 50 can correspondingly control the display unit 60 to display the corresponding preset light or color according to the current brain wave signal obtained from the brain wave detecting module 20, so as to provide a way of identifying the current brain wave state of the wearer.

Next, please refer to fig. 4, which is a schematic diagram of a headset for guiding brain waves according to another embodiment of the present invention. The frame 10 in this embodiment has a left arm portion 13A and a right arm portion 13B connected to the left and right ends of the eye cup portion. The left arm portion 13A and the right arm portion 13B have deformation portions 13A1 and 13B1 that are deformable with respect to the eye mask portion 11, so that the frame 10 has a certain degree of clamping force at both ears. On the other hand, the left arm portion 13A and the right arm portion 13B may be coupled to the eye cover 11 by a limiting member (not shown), and the limiting members may be adjusted to limit the angles of the left arm portion 13A and the right arm portion 13B relative to the eye cover 11, so that the left ear portion 12A and the right ear portion 12B may generate clamping force to the right ear and the left ear, respectively.

Referring to fig. 5, a partial cross-sectional structure diagram of a first type of electroencephalogram detection component of a head-mounted device according to another embodiment of the present invention is shown. The first type brain wave detecting element 21 includes: the pad 213, the extended sensing electrode 211, and the signal deriving part 215. The extended sensing electrode 211 is covered by the pad 213 and partially exposed out of the surface of the pad 213, preferably about 1mm, so as to have better contact effect when the extended sensing electrode 211 is attached to the left and right ears of the wearer. The signal deriving part 215 is coupled to the extended sensing electrode 211 and is partially covered by the pad body 213. The signal deriving part 215 is also used to couple with the substrate of the control module 50, so that the first type brain wave detecting element 21 can be coupled with the control module 50 through the signal deriving part 215, and further transmit the detected signal to the control module 50. The signal deriving part 215 may be a Pogo Pin (Pogo Pin) or a copper pillar.

The pad 213 has a fixing portion 2131 and an elastic portion 2133. The extended sensing electrode 211 and the signal deriving part 215 may be partially covered by the fixing part 2131, and further fixed to the pad 213. The elastic portion 2133 partially covers the fixing portion 2131, so that the cushion body 213 can provide buffering by the way that the elastic portion 2133 abuts against the frame 10, thereby improving the wearing comfort. The elastic portion 2133 may be silicone, thermoplastic Polyurethane (TPU), thermoplastic rubber (TPR), thermoplastic elastomer (thermoplasticelastomer), or other material of the same or similar nature. The pad 213 may be formed in a surrounding ring shape or a covering sheet shape when mounted on the frame 10. When the pad 213 is ring-shaped, the sound effect unit is exposed in the middle; when the pad 213 is in the form of a cover sheet, the aforementioned sound effect units may be integrated into the pad 213.

As shown in fig. 5, the extended sensing electrode 211 may be in a sheet shape, and is bent downward at the upper and lower sides and then extended into the fixing portion 2131, so that the extended sensing electrode 211 has a protrusion exposing the surface of the pad body 213, and further, the shape of the protrusion on the pad body 213 may be in a C shape as shown in fig. 1; in addition, the pad 213 protruding out of the surface of the frame 10 may be substantially circular on the frame 10 (see fig. 1).

The first type brain wave detecting element 21 can be coupled to the frame 10 by adjusting the screwing depth of the first type brain wave detecting element 21 by a spiral structure (not shown) formed on the bottom of the pad 213, so as to adjust the tightness of the first type brain wave detecting element 21 for holding the wearer. In addition, the frame 10 may also include a first magnetic member (not shown) at a position corresponding to the ear by means of a magnetic structure, and the first type brain wave detecting element 21 may be detachably coupled to the frame 10 by a second magnetic member (not shown) disposed at the bottom of the pad 213.

Referring to FIG. 6, which is a cross-sectional view of the embodiment shown in FIG. 3 under the AA section line, FIG. 6 is only an example of the pad 213 and the structure for fixing the pad 213. In this embodiment, the pad 213 is in a surrounding ring shape, and the extended sensing electrode 211 partially exposed out of the surface of the pad 213 is also in a surrounding shape with the pad 213, such surrounding can be corresponding to the ear part of the wearer. The fixing portion 2131 of the pad 213 may be a plastic material, for example, formed by mixing ABS resin (acrylonitrile butadiene Styrene) with PC material (Polycarbonate), and is used for injection molding in an embedding manner to partially cover the extension sensing electrode 211. The elastic portion 2133 of the pad 213 covers the fixing portion 2131 and the extended sensing electrode 211, for example, is formed by injection molding, so that the extended sensing electrode 211 can be fixed in the pad 213, and the pad 213 has elasticity at the portion contacting the ear of the wearer to relieve the pressure generated during the abutting.

The extended sensing electrode 211 is in the shape of a sheet, and has a bending portion bent downward at a side edge and a protruding portion bent again to extend into the fixing portion 2131. The protrusion can be used for coupling the signal guiding portion 215, the signal guiding portion 215 can be partially covered by the fixing portion 2131 and fixed at the bottom of the pad 213 for coupling with the signal connector 1415 disposed on the frame 10; in addition, in other embodiments, the extended sensing electrode 211 can also be directly electrically connected to the signal connector 1415 through a protrusion, for example, the protrusion is partially exposed at the bottom of the pad 213 for direct contact of the signal connector 1415, and further, the signal lead-out portion 215 is not required.

Further, the pad 213 may be designed to be removably detachable from the frame 10. For example, as shown in fig. 6, a mounting seat 14 is provided on the frame, and the mounting seat 14 may have a base 141 and a lifting member 143. The base 141 may be fixed to the frame 10 by various methods. The first type brain wave detecting assembly 21 can be matched with the first combination portion 1413 disposed on the base 141 by the second combination portion 2135 disposed on the fixing portion 2131, so that the first type brain wave detecting assembly 21 can be detachably connected to the frame 10. The first assembly portion 1413 and the second assembly portion 2135 can be magnetic members, respectively, and can be detachable by magnetic attraction.

The lifting member 143 can be screwed to the base 141 by a screw structure as shown in fig. 6, so as to adjust the distance between the first type brain wave detecting element 21 disposed on the mounting seat 14 and the ear by a screw method. When the lifting member 143 is rotated out to protrude from the base 141, the distance between the first type brain wave detecting element 21 and the ear is closer. However, it is not limited thereto, and various structures can be applied, which can be adjustable in the extent of protruding out of the base 141, so that the distance between the first type electroencephalogram detecting element 21 and the ear can be controlled.

In addition, based on the aforementioned examples of the first combination portion 1413 and the second combination portion 2135, the first combination portion 1413 may be disposed on the base 141 or the lifting member 143. And, the signal connector 1415 disposed on the base 141, for example, can be a spring probe, to adaptively match the first type brain wave detecting element 21 capable of being adjusted to be close to the ear, that is, when the first type brain wave detecting element 21 is closer to the ear (i.e., farther away from the frame), the spring probe is compressed less to protrude more to contact the first type brain wave detecting element 21 (e.g., contact the signal deriving portion 215).

Referring to fig. 7, a schematic perspective exploded view of a cushion body and a mounting seat according to an embodiment of the invention is shown. The first brain wave detecting assembly 21 is movably disposed on the mounting base 14, and the lifting member 143 is screwed to the screw structure on the inner peripheral wall surface of the through hole of the base 141 by the screw structure on the outer peripheral surface of the annular body, so as to adjust the degree of protrusion of the lifting member 143 out of the base 141.

Next, please refer to fig. 8, which is a schematic diagram of a head-mounted device for guiding brain waves according to another embodiment of the present invention. In this embodiment, the right ear 12B and the left ear 12A of the frame 10 of the head-mounted device HD are used to approximate the ends of the eyeglasses frame and extend to the upper root of the corresponding ear. The frame 10 of the right ear 12B and the left ear 12A may be respectively provided with an extended sensing electrode 211 for touching the upper root of the corresponding ear and the upper end of the helix. The sensing electrodes of the extended sensing electrodes 211 are in contact with the sensing electrodes of the adjacent parts of the upper ear root by their longer and wider areas and arc surfaces, so as to contact the ear at multiple parts. In addition, the physiological signal measuring module (not shown) can also be disposed at the front end of the extended sensing electrode 211.

Referring to fig. 9, a cross-sectional view of a pad and a mounting seat according to another embodiment of the invention is shown. The pad 213 presents an enclosure, such as a ring as shown in fig. 9, on the mount 14. To further increase the contact area with the wearer's ear, the extended sensing electrode 211 partially covered in the pad 213 may expose the sensing electrode at the top of the pad 213 and the inner circumference of the ring. As shown in fig. 9, the extended sensing electrode 211 has an inclined surface inclined toward the edge of the pad 213 on the wall surface of the inner periphery of the ring, and is fixed in the pad 213 by the fixing portion 2131 and the elastic portion 2133. The exposed sensing electrode part with larger area can further improve the sensing performance.

Referring to fig. 10, a flowchart of a method for guiding brainwaves according to an embodiment of the present invention is shown. The method comprises the following steps: (S100) measuring a first brain wave signal of the wearer; (S200) executing a predetermined stimulation mode to provide an initial stimulation signal having a stimulation effect; (S300) measuring a second brain wave signal of the wearer; (S400) obtaining a brain wave variation degree according to the first brain wave signal and the second brain wave signal; (S500) providing a guiding stimulation signal according to the brain wave variation degree and the currently obtained third brain wave signal to influence the current brain wave of the wearer.

In the embodiment of fig. 10, the degree of the current brain wave change when the wearer is subjected to a certain degree of external stimulation is measured, and based on this pretest, the current brain wave state of the wearer can be determined, i.e., the degree to which the wearer can be guided at present can be known, so as to determine the guiding stimulation mode to guide the wearer.

Based on the type of dominant brainwaves (α, β, δ, θ), different states of consciousness may be assigned. Wherein, when the alpha wave is dominant, the bridge is in a bridge consciousness state from waking to relaxing; when the beta wave is dominant, it represents a state of consciousness, and this type of brain wave appears in a state of anxiety, thinking or mental concentration under wakefulness; when the delta wave is dominant, the brain wave is in an unconscious state, and the brain wave of the type generally appears when the non-rapid eye movement sleeps; theta waves are dominant and represent a state of subconscious mind, and brain waves of this type generally occur in deep dreams or deep meditation.

Therefore, after the difficulty degree of brain wave guiding is judged by giving stimulation, a better stimulation mode which achieves a preset guiding target can be given to a wearer, and the guiding efficiency is improved.

Further, the predetermined stimulus pattern and the guided stimulus signal provide a corresponding predetermined acousto-optic test pattern to the wearer, the predetermined acousto-optic test pattern including variations in light parameters and frequency differences between the left and right ears over a specified period of time. The change of the light parameters and the left and right ear frequency difference at least comprises the change sequence of the light from more red light, more yellow, more green to more blue light and the reverse change sequence thereof or the change sequence of the left and right ear frequency difference from 12Hz to 2Hz and the reverse change sequence thereof.

The frequency difference variation of the high frequency is, for example, between 200 and 210Hz corresponding to each ear variation (but the frequency difference is gradually adjusted from 12Hz to 2Hz or gradually adjusted in the reverse order), and the frequency difference variation of the low frequency is, for example, between 170 and 173Hz (but the frequency difference is gradually adjusted from 12Hz to 2Hz or gradually adjusted in the reverse order), so that the good effect is achieved. The change of the light is divided into orange (reddish) corresponding to a light consciousness refreshing state, orange (yellowish) corresponding to a subconscious relaxing state, blue-green (greenish) corresponding to a light sleep guide and blue-green (bluish) corresponding to a deep sleep guide, light stimulation can be given corresponding to the currently measured brain wave state progressively according to the preset acousto-optic test mode, and the light is changed to the light corresponding to the target state gradually based on the target state of the preset guide.

In the example of guiding the wearer to sleep, the brain wave changes corresponding to the consciousness state of smooth sleep are four main stages of beta wave, alpha wave, theta wave and delta wave. If the degree of change of the brain wave of the wearer is normal (i.e. it is not difficult to guide), and the third brain wave signal is an α brain wave, that is, the current consciousness state is a bridge consciousness state, the control module 50 controls the light parameter given within a certain time (e.g. 5 minutes, 10 minutes) and the change of the left and right otofrequency differences to be changed from the α wave frequency band to the θ wave frequency band, for example, the frequency of the light flashing per second is changed from 10Hz to 5Hz, and/or the left and right otofrequency differences are changed from 10Hz to 5Hz.

Accordingly, the head-mounted device HD of the embodiment can guide the brain waves of the wearer by light and sound, assist the wearer to enter a specific consciousness state (such as light sleep, deep sleep and the like), help the wearer to enter a sleep stage more quickly and further achieve a better rest effect; in addition, by sensing the brain wave of the wearer in real time through the head-mounted device HD, which consciousness state the wearer is in at present can be judged, and the consciousness state of the wearer tending to deep sleep is further guided correspondingly, so that the sleep quality of the wearer is improved.

Accordingly, in addition to guiding the wearer to the consciousness state of deep sleep, the operation can be reversed, so that the wearer tends to the consciousness state of waking up, and the function of waking up can be realized.

Accordingly, the control module 50 of the head-mounted device HD in the embodiment of the present invention can calculate and summarize an obtained brain wave variation degree based on the first brain wave signal S20 received from the brain wave detecting module 20 and based on the brain wave guiding module 30 being operated in a predetermined stimulation mode, so that the brain wave guiding module 30 provides a guiding stimulation signal. Can apply a better guiding mode according to the current brain wave conditions of different wearers, thereby improving the guiding efficiency.
