Description

Technical Field

[0001] This disclosure relates to the field of transcranial phototherapy equipment technology, and more specifically, to a control method and control components for a head-mounted device and a head phototherapy device. Background Technology

[0002] Studies have shown that light of a certain wavelength can penetrate the human skull and stimulate cells to produce beneficial effects, thereby achieving the purpose of treating brain diseases. For example, some studies have shown that near-infrared light with a wavelength of 810nm can be used to treat Alzheimer's disease.

[0003] Light has a certain degree of penetrability and thermal effect. When using transcranial phototherapy devices, if the light irradiation mode is activated incorrectly or not at all, it can easily damage the user's vision. For example, near-infrared shortwave light can be absorbed by the lens and iris, causing cataracts. However, existing transcranial phototherapy products lack corresponding safety protection designs. Summary of the Invention

[0015] In a third aspect, embodiments of this disclosure provide a control component for a head-mounted device, applied to the head-mounted device, the head-mounted device having a receiving space for receiving a head, and including a light application module for applying transcranial light to the head, comprising: at least two sets of sensing components, wherein a first set of sensing components is used to detect whether a user's head is located within the receiving space using a first detection method; a second set of sensing components is used to detect whether a user's head is located within the receiving space using a second detection method; and a control unit is used to determine whether a user's head is present in the receiving space based on the detection results of the first set of sensing components and the second set of sensing components; and, if it is determined that a user's head is located in the receiving space, to send a control signal to activate the light application module or to place the light application module in an unlocked state that allows activation.

This can prevent transcranial light emitted when the light application module is improperly activated from causing harm to the user, thereby improving the safety of device use.

[0028] To enable those skilled in the art to better understand the technical solutions of this disclosure, the disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and specific examples, but these are not intended to limit the scope of this disclosure.

[0029] The terms “first,” “second,” and similar words used in this disclosure do not indicate any order, quantity, or importance, but are merely used for distinction. Words such as “including” or “contains” mean that the element preceding the word covers the element listed after the word, and do not exclude the possibility of covering other elements as well.

[0030] Embodiments of this disclosure provide a control method for a head-mounted device, such as... Figure 1aAs shown, the head-mounted device 1 has a receiving space for the head and includes a light application module (not shown) for applying transcranial light to the head. The head-mounted device 1 can be a phototherapy helmet, a phototherapy headgear, or a similar phototherapy product. The light application module can emit transcranial light, such as infrared light or near-infrared light. The light application module may include, for example, light sources such as LED lights or laser diodes and optical waveguide components mounted on the helmet. The light application module may also include fiber optic probes and optical waveguide components that guide transcranial light from other light sources into the helmet to irradiate the wearer's head. Other light sources refer to light sources that generate working light independently of the helmet, as long as the light application module can apply transcranial light to the user's head. This disclosure does not specifically limit this.

[0031] It should be noted that this disclosure uses an infrared module as an example to illustrate various embodiments of the present disclosure, but the present disclosure is not limited thereto.

[0032] like Figure 1b As shown, the control method of this disclosure includes:

[0033] In step S101, at least two detection methods are used to detect whether the user's head is located in the containment space. Based on the at least two detection results corresponding to the at least two detection methods, it is determined whether the user's head exists in the containment space.

[0034] The design concept of this invention is to comprehensively determine whether the user's head is located within the receiving space using different judgment logic designs (e.g., at least two), which is more reliable than a single judgment logic. For example, one judgment logic could be to determine whether the head-mounted device 1 is worn on the head by detecting whether there is an object resembling a head shape within the receiving space; another judgment logic could be to determine whether the head-mounted device 1 is worn on the head by detecting whether there is a living organism within the receiving space. In another embodiment, another judgment logic could be to determine whether the head-mounted device 1 is worn on the head by detecting whether the object within the receiving space has facial features, such as facial contours, eyes, nose, etc., features that can be used to identify the object within the receiving space as a head. Various judgment logics can be included, and not all will be listed here.

[0035] Each of the at least two detection methods described in this invention corresponds to a judgment logic. This disclosure collects the signals required by the at least two detection methods (with different judgment logic designs), and comprehensively determines whether a user's head exists in the accommodating space based on the at least two detection results corresponding to these detection methods. For example, when each detection method determines that the user's head has entered the accommodating space, it can be determined that the head-mounted device is worn on the user's head. Alternatively, reliability scores can be applied to the at least two detection results corresponding to the at least two detection methods, and a weighted total score can be calculated to determine whether the head-mounted device is worn.

[0036] It is understood that this disclosure does not specifically limit the testing order of the above-mentioned testing methods, as long as the inventive concept of this disclosure can be realized. For example, at least two testing methods can be performed simultaneously, in a predetermined order, or alternately at a predetermined interval.

[0037] Specifically, the at least two detection methods can be implemented by setting up sensor 11. For example, different types of sensors can be set at different locations in the accommodating space to implement at least two methods of detecting the user's head as disclosed herein, or the same type of sensor can be set up with different detection logic to implement at least two methods of detecting the user's head. Specific methods are not listed here.

[0038] In step S102, if it is determined that the user's head is located in the accommodating space, the light application module is turned on or the light application module is placed in an unlocked state that allows it to be turned on.

[0039] By establishing at least two detection methods to ensure the user's head is within the receiving space of the head-mounted device 1, the light application module is unlocked or activated only when proper positioning is achieved. This prevents transcranial light emitted from the light application module, if improperly activated, from harming the wearer, operator, or third party. Specifically, for example, children playing with the head-mounted device 1, or elderly people unfamiliar with its use, may misuse it, such as wearing it backwards, accidentally triggering the light application module switch. In such or similar situations, if the light application module is activated, the therapeutic effect cannot be guaranteed and safety issues, such as vision damage, are easily caused. The control method disclosed herein greatly improves the safety issues caused by the user accidentally activating the light application module when the device is incorrectly positioned or not worn, ensuring that the light application module is activated only when the head-mounted device is correctly worn, thereby guaranteeing the device's safety.

[0040] In some embodiments, the at least two detection methods include detecting whether an object within the containment space is a living organism. There are multiple logics for determining whether the head-mounted device 1 is worn on the head (i.e., whether the user's head is located within the containment space). One of the logics in this embodiment is to determine whether it is worn on the head by detecting whether an object within the containment space is a living organism. This embodiment does not limit the specific method used for living organism detection.

[0041] In one specific embodiment, the presence or absence of a living organism can be determined by detecting the physiological signals of an object within the containment space, thereby identifying whether it is the user's head. Specifically, a physiological sensor can be installed inside the head-mounted device 1 for head phototherapy to collect the physiological signals of the object within the containment space, thereby determining whether a living organism has entered the containment space.

[0042] In another specific embodiment, the head-mounted device 1 for head phototherapy may have multiple physiological sensors (adapted to head shape to detect head-like organisms) disposed inside, and these sensors are located in different positions. When multiple physiological sensors simultaneously detect physiological signals and determine that the organism is alive based on these signals, it can be determined that the head-mounted device 1 is worn on the head, at which point the light application module can be directly turned on or off. In the latter case, this embodiment first triggers the unlocking of the light application module so that it can be turned on when a subsequent activation command is received.

[0043] If the object entering the head-mounted device 1 is not a living organism (e.g., a soccer ball), it can be excluded based on whether physiological signals are collected. If the object entering the helmet or hood is a living organism but not a head, such as a hand inside the helmet or hood, the physiological sensors deployed at different locations cannot simultaneously collect physiological signals. This can be used to exclude the case of a hand entering the head-mounted device 1, thus ensuring that the light application module is only activated or unlocked when the head-mounted device 1 is correctly worn on the head. It should be noted that the above-mentioned "simultaneous collection of physiological signals" may be implemented in practice based on the premise that physiological sensors deployed at different locations can collect physiological signals within a certain time threshold range, specifically based on the probability of "detecting a head-like organism" meeting actual needs.

[0044] Multiple physiological sensors can be the same type of physiological sensor or different types of physiological sensors. For example, multiple physiological sensors can be a combination of temperature sensors and blood oxygen sensors. The specific placement locations can be at least two of the following: the forehead, the left and right temples, the top of the head, and the back of the head. Placing them in these areas allows for convenient collection of physiological signals from the user's head.

[0045] Independently or additionally, the at least two detection methods may further include detecting whether a spherical object exists within the accommodating space. For example, sensors can be placed at different positions along the circumference of the accommodating space. When these sensors simultaneously detect an object, it can be determined with a high probability whether a spherical object exists within the accommodating space. Thus, based on the sensor signals from different positions, it can be determined whether the object within the accommodating space is the user's head. The sensors can be, for example, pressure sensors or proximity sensors. For example, multiple proximity sensors can be placed within the head-mounted device, each positioned at a different location inside the head-mounted device 1. If multiple placement points simultaneously detect an object approaching, it can be assumed that the head-mounted device 1 has been worn on the user's head, or that at least an object resembling a head has entered the head-mounted device 1. Since multiple proximity sensors are placed at different locations inside the head-mounted device 1, it is difficult for multiple placement points to simultaneously detect an object approaching if the user holds the head-mounted device 1. The specific placement and arrangement of the multiple proximity sensors are determined to improve detection accuracy, and this embodiment does not impose specific limitations.

[0046] As another specific implementation, detecting whether a spherical object exists in the containment space may further include: using multiple proximity and / or contact sensors arranged at different circumferential positions in the containment space to detect whether a spherical object exists in the containment space; when the multiple proximity and / or contact sensors simultaneously detect that an object is approaching and / or in contact, it is determined that a spherical object exists in the containment space.

[0047] For example, four proximity sensors are installed inside the head-mounted device 1, evenly distributed on the inner side of the device. These four sensors are positioned on the inner side of the head-mounted device, corresponding to the top, sides, and back of the wearer's head, respectively. Alternatively, three proximity sensors can be installed inside the head-mounted device 1, positioned on the inner side of the head, corresponding to the top, forehead, and back of the wearer's head, respectively. The detection method in this embodiment requires fewer sensors and has a higher detection accuracy.

[0048] This embodiment does not limit the specific number or placement of sensors, as long as they can detect head-like shapes. When multiple proximity sensors simultaneously detect an approaching object, it can be determined that a spherical object exists in the containment space, and a head can be identified with a high probability. The arrangement of contact sensors or a mixed arrangement of contact sensors and physiological sensors is similar and is not limited here.

[0049] The aforementioned proximity sensors can be infrared proximity sensors, capacitive proximity sensors, and ultrasonic distance sensors, as well as other sensors capable of detecting the approach of objects within a certain distance range. Contact sensors can include pressure sensors, as well as other sensors capable of detecting the contact of objects. The detection range of proximity sensors is generally less than 2 cm. Proximity sensors that sense objects at close range include magnetic (inductive), barometric, and photoelectric sensors; specific sensor types are not limited here. For example, as a deployment method, if a pressure sensor is installed inside the wearer's head-mounted device, proximity sensors can be placed at the edges of the head-mounted device. Specific placement locations could include one proximity sensor on the top inside the head-mounted device, one physiological sensor on the forehead, or other locations such as the temples. Proximity sensors can also be replaced with pressure sensors, or multiple pressure sensors or proximity sensors can be installed. Furthermore, a capacitive proximity sensor can be used. The capacitive proximity sensor can be pre-optimized for sensitivity based on the detected object (hair and scalp), and can detect the approach of the head when hair and / or scalp are close to the capacitive proximity sensor. Multiple capacitive proximity sensors are placed at different locations along the inside of the head-mounted device. When these multiple capacitive proximity sensors at different locations simultaneously detect an object approaching, it can be determined with a high probability that the head has entered the containment space.

[0050] For example, an infrared sensor can be used with a detection distance of less than 2 cm. Infrared sensors can be either through-beam proximity sensors or diffuse reflection infrared sensors. Using infrared sensors offers advantages such as mature technology, low cost, and a suitable size for productization, making them suitable for market promotion. Furthermore, when using infrared sensors, a filter can be added to the receiver to filter out the corresponding wavelength of transcranial light used in phototherapy, as well as other ambient light that might affect the detection effect. This prevents the light used in phototherapy from interfering with the infrared sensor, allowing it to detect whether the head has detached from the helmet or headgear even after phototherapy has begun, provided the transcranial light is present.

[0051] As an example of detection method, multiple proximity and / or contact sensors positioned circumferentially within the containment space can be used to detect the presence of a spherical object. Then, if a spherical object is detected, a physiological sensor can be used to determine whether the object is a living organism. Detecting the presence of a spherical object within the containment space can be achieved using proximity and / or contact sensors; generally, detection can be performed without physical contact, signal processing is simple, and the response speed is fast. Specifically, when detecting whether an object has entered a head-mounted device, multiple sensors can be used to collect signals to determine whether a head-like object has entered the device. Detecting whether an object within the containment space is a living organism can be achieved by collecting physiological signals using physiological sensors. Collecting physiological signals requires relatively stringent environmental conditions and takes considerable time; the collected physiological signals also require feature signal comparison, resulting in a large computational load and a relatively slow response. This example proposes to perform physiological detection only when a spherical object is detected entering the system, and not to perform physiological signal detection when no spherical object is detected, such as when only an object (like a human hand) is detected. This achieves the goal of rapid response and power saving.

[0052] As an example of a detection method, the detection order of the above at least two detection methods may not be required. For example, the detection of spherical objects and biological liveness detection can be performed simultaneously, or biological liveness detection can be performed first and then spherical object detection can be performed.

[0053] In some embodiments, multiple physiological sensors disposed at different circumferential positions in the containment space can be used to detect whether a spherical object is a living organism while simultaneously detecting the presence of such an object in the containment space.

[0054] Alternatively, multiple proximity sensors and at least one physiological sensor positioned at different circumferential locations within the containment space can be used to first detect whether the object within the containment space is a living organism, and then to detect whether the living organism within the containment space is a spherical object. Regardless of the order of the two detection methods, the presence of a user's head within the containment space can be determined only when both conditions are met simultaneously (a spherical object exists within the containment space, and the physiological signal indicates it is a living organism), meaning the head-mounted phototherapy device is worn on the user's head, allowing for safe activation or deactivation of the light application module.

[0055] By employing multiple detection methods from different angles (with different judgment logics) to determine whether the helmet or hood is worn, the likelihood of accidental opening or unlocking of the light application module during abnormal use can be greatly reduced, resulting in higher reliability.

[0056] It should be noted that the specific type, location, and method of sensor placement are determined based on achieving the detection objective. For spherical objects, sensors such as proximity sensors, pressure sensors, or combinations thereof can be used. By deploying multiple points, the head-like shape can be detected, preventing accidental opening or unlocking of the light application module when the head-mounted device 1 is held. The sensors for detecting living organisms described in this embodiment are understood as any components capable of acquiring signals used to determine whether an organism is living. Sensors for detecting living organisms generally achieve this by acquiring physiological signals, i.e., by deploying at least one physiological sensor. Physiological sensors can also be temperature sensors; for example, if the temperature acquired by the temperature sensor is within the characteristic range of human body temperature, it is considered a living organism. Other sensors include one or more biochemical sensors such as blood flow sensors, blood pressure sensors, heart rate monitoring sensors, blood oxygen sensors (transcutaneous oxygenation sensors), pulse sensors, electromyography sensors, ECG sensors (electrocardiogram sensors), and electrodermal activity sensors. At least one such sensor can be placed at a location corresponding to exposed skin on the head, such as the forehead, ears, neck, or other areas not covered by hair, to facilitate the acquisition of physiological signals.

[0057] After determining whether a user's head exists in the accommodating space, the control method in this embodiment further includes: sending information including at least one of the following: detection results corresponding to the at least two detection methods, wearing information indicating the wearing status of the head-mounted device, and an on / off command for the light application module.

[0058] By utilizing the sensor deployment methods described in the various embodiments of this disclosure to detect the wearing of the head-mounted device 1, or when it is determined, based on at least two detection results, that a user's head is present in the receiving space, the light application module can be activated or placed in an unlocked state that allows activation. This embodiment transmits such a message using the aforementioned information. For example, this information may carry wearing information indicating the wearing status of the head-mounted device. If this information is not received within a preset timeframe for initiating wearing detection, it can also be determined that no user's head has been detected in the receiving space. The control unit can perform subsequent process control based on this information, such as activating the light application module upon receiving the information.

[0059] In some embodiments, the aforementioned information can be sent in the following manner, which may also directly include an instruction to turn on / unlock the light application module or an instruction to generate such an instruction. In some embodiments, the sent information may also include wearing information indicating the wearing status of the head-mounted device. For example, if not worn correctly, this information is used to trigger a voice prompt such as "Please wear the helmet correctly." If worn correctly, this information is used to trigger a voice prompt such as "Helmet worn, do you want to start light therapy?" This method can further ensure that the light application module is not accidentally turned on and causes eye damage. For example, when the physiological sensor determines that the head-mounted device is correctly worn on the head, the locking switch of the light application module is opened, making the light application module in an openable state. Whether it is subsequently turned on is determined by the light application module turn-on instruction signal, which may be, for example, an open button or a user response to the interface operation feedback signal. When it is determined that the head-mounted device is worn, a voice prompt "Headpiece worn, do you want to start light therapy?" is issued when the operator presses confirmation. If the light application module is unlocked, the light application module is turned on. If the light application module is not unlocked, it will not be activated even if there is an activation command, thus avoiding the problem of the light application module being accidentally activated.

[0060] In some other embodiments, corresponding prompts can be provided to the user based on the detection results of the at least two detection methods. Specifically, this can be achieved through the detection result information carried by the aforementioned information, providing different prompts based on different detection results, and further, enabling different process controls.

[0061] For example, if sensors are arranged at multiple locations inside the head-mounted device to detect the presence of a spherical object in the containment space; and physiological sensors are also arranged to detect the presence of a living organism in the containment space, when a spherical object is detected but no physiological signal is detected, the user can be prompted with "No physiological signal detected. Please check if the XX position of the headgear is in contact with the skin, or if the headgear is being worn on the head of a living organism." The XX position refers to the location of the physiological sensor on the headgear; many physiological sensors generally require close contact with the skin to easily collect signals.

[0062] For example, when only physiological signals are detected, but sensors deployed at multiple locations do not simultaneously detect signals (i.e., it cannot be determined that a spherical object has been detected), the detection results carried by the above information may also include: the numbers of sensors that did not detect any object contact or approach (and / or the numbers of sensors that detected signals indicating object contact or approach). Based on this information, different wearing prompts can be triggered. For example, if the pressure sensor located on the top of the head does not detect pressure, but sensors deployed at other locations detect an object approaching, the user can be prompted with targeted prompts such as "Headpiece detected, but not worn correctly" or "Please pull down / move the headpiece down so that the inside of the top of the headpiece fits snugly against the head."

[0063] For example, when no physiological signal is detected, and the sensors deployed at multiple locations do not detect a signal or only a few do, the user is prompted with "No headgear detected, please wear the headgear correctly".

[0064] In some embodiments, such as Figure 2 As shown, the head-mounted device 1 also includes a strap with a buckle 2. A sensor (such as a Hall sensor or an electromagnetic sensor) can be installed on the buckle 2 to detect whether the buckle 2 is engaged. Similarly, the detection of whether the buckle 2 is engaged can be replaced by other strap detection methods that can achieve similar functions, which will not be listed here.

[0065] For example, in some embodiments, the strap detection (such as detecting whether buckle 2 is engaged) can be one of the at least two detection methods, that is, strap detection is one of the headgear wearing detection methods. When the strap is detected to be fastened by buckle or other means, it can also be determined with a certain probability that the headgear is worn. In some embodiments, the at least two detection methods include: buckle 2 engagement detection and the above-mentioned spherical object detection, or biological liveness detection. Further, when buckle 2 is detected to be engaged, other detection methods among the at least two detection methods are triggered.

[0066] The strap detection may not be one of the at least two detection methods described above for headwear wearing detection. In some embodiments, strap detection may also be included in addition to the at least two detection methods described above. When it is determined that the headwear is worn, information is obtained regarding whether the strap buckle 2 is engaged. If it is engaged, a voice prompt appears: "Headwear is worn, start light therapy?" The operator presses confirmation, and the light application module is activated. If it is not engaged, a prompt appears: "Please fasten the buckle." The specific interaction process with the operator can also be found in the aforementioned embodiments.

[0067] In other embodiments, in addition to the at least two detection methods described above for headwear wearing detection, a strap detection method may also be included. Before starting the at least two detection methods for headwear wearing detection, it is determined whether the strap buckle 2 is engaged. If the buckle 2 is detected to be engaged, the at least two detection methods described above are triggered to detect whether the headwear is worn.

[0068] That is, in some embodiments, before detecting whether a user's head is in the containment space, the control method further includes: acquiring second information; and triggering the execution of the step of detecting whether the user's head is located in the containment space using the at least two detection methods based on the second information. Specifically, the second information may be pre-requisite information for triggering the execution of the at least two detection methods, such as the aforementioned engagement information or a notification message indicating that the head-mounted device has left a preset position, or operation information issued by an operation button, etc. In some examples, after the engagement sensor of the buckle 2 issues an engagement signal, the engagement signal can be used to trigger the aforementioned physiological sensor or proximity sensor to open. That is, the second information may be a buckle engagement signal; once the buckle 2 is engaged, the detection of whether there is an object or a living organism inside the head-mounted device 1 can begin, thereby further reducing the energy consumption of the head-mounted device 1.

[0069] In some embodiments, the head-mounted device 1 can be placed on a support by default, and a trigger point can be provided on the support to detect whether the head-mounted device 1 has left the support. Independently or additionally, before detecting whether a user's head is in the receiving space, second information is acquired. This second information may be information about the head-mounted device 1 leaving the support (i.e., the second information may also be a trigger signal from the trigger point). Based on this second information, the step of detecting whether the user's head is located in the receiving space using at least two detection methods is triggered. This disclosure initiates head-mounted device detection only when the head-mounted device 1 leaves the support (corresponding to the case where the user removes the headgear from the support). This method allows control over the timing of detecting the user's head, thereby further controlling the sensor's power consumption.

[0070] In some embodiments, when it is determined that the user's head is located in the accommodating space, the control method further includes: obtaining third information, and based on the third information, activating the light application module or placing the light application module in an unlocked state that allows activation.

[0071] The third piece of information may be other conditions required to turn the light application module on or off. These other conditions may include whether the eye protection device is worn correctly or whether the power supply conditions of the light application module are met. This third piece of information may also be combined with the aforementioned information (the detection results corresponding to at least two detection methods and the wearing information, etc.) to place the light application module in an unlocked state that allows it to be turned on.

[0072] Independently or additionally, such as Figure 3 The head-mounted device 1 shown may also include an eye protection device 3. The detection of eye protection device 3's wear can be performed independently of headwear wear detection, or it can be included in or combined with headwear wear detection. The eye protection device 3 is equipped with an eye information acquisition unit, and the control method further includes: based on the first information acquired by the eye information acquisition unit that characterizes the human eye, activating the light application module or placing the light application module in an unlocked state that allows activation.

[0073] The independent wearing detection of the eye protection device 3 can be accomplished through an eye information acquisition unit. This unit can be an image acquisition module (capturing blinking movements) or a sensor, such as a pressure sensor or temperature sensor. The acquired primary information representing the human eye can be, for example, blinking movements or physiological signals of the eye, as long as it can identify the eye; no specific limitation is made here. An exemplary implementation using sensors is described below:

[0074] In some embodiments, for example, the eye protection device 3 is an eye shield fixed to the head-mounted device 1. A physiological sensor is disposed on the eye shield as an eye information acquisition unit. Detecting whether an object in the containment space is a living organism may include: using the physiological sensor to detect the physiological signals of the object in the containment space; and simultaneously determining whether the eye protection device is worn based on the detection results of the physiological sensor. In use, the eye protection device can fit snugly against the periphery of the eyes, and the aforementioned physiological sensor is placed at this fitting position to simultaneously realize the acquisition of physiological signals and the detection of the wear of the eye protection device. Specifically, the physiological sensor on the eye protection device 3 can be, for example, a temperature sensor, a blood oxygen sensor (transcutaneous oxygen sensor), an electromyography sensor, or any other physiological sensor. The signals acquired by the physiological sensor are processed to determine whether the signal can match a preset eye feature signal. If a match is found, the human eye is identified, and the light application module is placed in an unlocked state that allows it to be opened.

[0075] In some embodiments, the head-mounted device further includes an eye protection device, and the control method further includes: acquiring eye feature data using an eye information acquisition unit disposed on the eye protection device; determining the wearing state of the eye protection device based on the eye feature data; and, when the eye protection device is in the correct wearing state, activating the light application module or placing the light application module in an unlocked state that allows activation. The eye feature data refers to digitized eye features that can be used to identify the eyes. For example, the eye feature data may be eye images, blink frequency, electrooculogram signals, pupil data, etc., and may also be, for example, a temperature sensor.

[0076] Specifically, the eye information acquisition unit on the eye protection device 3 can be an eye recognition device, an electrooculogram signal acquisition device, a blink frequency acquisition device, a pupil data acquisition device, etc. It can determine whether the user has correctly worn the eye protection device 3 based on features such as eye recognition and blink frequency. If the acquired eye feature data does not meet the preset requirements or no eye feature data is acquired, it can be determined that the eye protection device 3 is not worn in the target position or is not worn at all. At this time, the light application module will not be turned on.

[0077] This embodiment can also detect the wearing position of the eye protection device 3 by detecting the wearing of the eye protection device 3, ensuring that the eyes are protected before activating the light application module, thereby achieving all-round protection and preventing the light application module from being accidentally activated.

[0078] In some embodiments, after the light application module is turned on or off, the control method further includes: monitoring whether the user's head is located in the containment space using at least one monitoring method; and if the monitoring results indicate that there is no user's head in the containment space or at least part of the user's head has left the containment space, turning off the light application module or placing the light application module in a locked state that does not allow it to be opened.

[0079] It is understandable that other sensors can be used to monitor whether the user is within the receiving space in real time, or at least one of the above detection methods can continue to be used to monitor whether the user's head is within the receiving space. That is, the sensors corresponding to at least one of the above detection methods are not turned off during the phototherapy process. If the monitoring results determine that the user's head is not in the receiving space or that the user's head has partially left the receiving space, the light application module is turned off or placed in a locked state that does not allow it to be opened. In this way, if the operator is detected to be removing the head-mounted device 1, the light application module can be turned off immediately, thereby ensuring that even in the event of an erroneous operation such as accidental removal, the light application module will not cause harm to the user or a third party.

[0080] In some embodiments, the present disclosure provides a control method for a head-mounted device. The method determines whether a headgear is worn by detecting pressure on the inner side of the top of the head and whether the strap buckle is engaged. Specifically, the sensors in the headgear are arranged as follows: a pressure sensor is located on the inner top of the headgear, and a strap buckle sensor is located on the strap. The control method for the headgear provided by the embodiments of the present disclosure acquires signals through the pressure sensor and the strap buckle sensor respectively. Only when the pressure sensor acquires a pressure signal and the strap buckle sensor detects that the buckle is engaged is the headgear determined to be worn, and the light application module is then activated or deactivated. In other embodiments, a physiological sensor may be further included, located on the forehead of the headgear or in other locations such as the ear.

[0081] like Figure 4 In another embodiment shown, multiple proximity sensors 41 are disposed inside the helmet, and at least one temperature sensor 42 is disposed on the forehead or eye area. The multiple proximity sensors 41 and at least one temperature sensor 42 are connected to a control unit (not shown), which may be, for example, an AND gate. The proximity sensors 41 output a first enable signal only when an object is detected approaching. The temperature sensor 42 converts the collected temperature information into an electrical signal and determines whether it is a living organism by using, for example, a window comparator to determine if it is a characteristic temperature of a human body. The threshold of the window comparator is set according to the measurement accuracy of the temperature sensor 42, i.e., within the range of human characteristic temperatures. For example, the human characteristic temperature range can be obtained based on the statistical temperature of a generally healthy person, for example, it can be set to 36 to 38 degrees Celsius. When the detected temperature is between 36 and 38 degrees Celsius, the detected object can be considered a living organism. The temperature sensor 42 can be integrated with a window comparator or a similar functional device. Alternatively, the window comparator or a similar functional device can also be integrated with the control unit.

[0082] Temperature sensor 42 outputs a second signal within a set threshold temperature range via a window comparator or similar functional component. This signal is then ANDed with the first signal from pressure sensor to output a signal that unlocks the light application module.

[0083] When multiple proximity sensors 41 detect an approaching object, and the temperatures collected by the temperature sensor 42 are consistent with human body temperature, it is determined that the helmet or headgear has been put on the user's head. The system then controls the light application module to be turned on or unlocks the light application module so that it can be turned on when an activation command is received.

[0084] Embodiments of this disclosure provide a control component for a head-mounted device, the control component including a processor and a memory, the processor being configured to execute one or more computer programs stored in the memory to implement the steps of the control method for the head-mounted device described in the embodiments of this disclosure. The processor in this example may be a processing device including one or more general-purpose processing devices, such as a microprocessor, a central processing unit (CPU), a graphics processing unit (GPU), etc. More specifically, the processor may be a Complex Instruction Set Computing (CISC) microprocessor, a Reduced Instruction Set Computing (RISC) microprocessor, a Very Long Instruction Word (VLIW) microprocessor, a processor running other instruction sets, or a processor running a combination of instruction sets. The processor may also be one or more special-purpose processing devices, such as an Application-Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), a Digital Signal Processor (DSP), a System-on-Chip (SoC), etc. In this example, the memory can be a non-transitory computer-readable medium, such as read-only memory (ROM), random access memory (RAM), phase-change random access memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), electrically erasable programmable read-only memory (EEPROM), other types of random access memory (RAM), flash drives or other forms of flash memory, cache, registers, static memory, optical disc read-only memory (CD-ROM), digital versatile optical disc (DVD) or other optical storage, magnetic tape cassette or other magnetic storage devices, or any other possible non-transitory medium used to store information or instructions that can be accessed by computer equipment.

[0085] Embodiments of this disclosure also provide a control component for a head-mounted device, applied to the head-mounted device, the head-mounted device having a receiving space for receiving a head, and including a light application module for applying transcranial light to the head, for example, the light application module can be as follows: Figure 5 The infrared module 53 shown includes a control component comprising at least two sets of sensing components (501-50n), wherein a first sensing component 501 is used to detect whether the user's head is located within the accommodating space using a first detection method; and a second sensing component 502 is used to detect whether the user's head is located within the accommodating space using a second detection method. A control unit 52 is used to determine whether a user's head is present in the accommodating space based on the detection results of the first and second sensing components; and, if it is determined that the user's head is located within the accommodating space, to send a control signal to activate the infrared module 53 or to place the infrared module 53 in an unlocked state where activation is permitted.

[0086] The control unit 52 disclosed herein can be integrated with or separated from the head-mounted device. In the integrated configuration, the control unit 52 can be placed on the head-mounted device, and interactive buttons can also be provided on the head-mounted device. In the separated configuration, it can be designed independently of the head-mounted device, controlling wear detection via wired or wireless means, thereby controlling the phototherapy process of the head-mounted device. Specific sensor arrangements are described in the foregoing embodiments and will not be repeated here. By setting at least two sets of sensing components to activate the light application module only when the wearer's head is detected, the possibility of accidental activation of the light application module due to objects such as hands or spherical objects entering the head-mounted device can be eliminated, improving user safety when using the head-mounted device.

[0087] In some embodiments, the first sensing component 501 is used to detect whether a spherical object exists within the containment space; the second sensing component 502 is used to detect whether the object within the containment space is a living organism; and the control unit 52 is configured to determine that the user's head is located within the containment space when a spherical object is detected within the containment space and the object is a living organism. The steps of detecting the presence of a spherical object and detecting whether it is a living organism can be performed separately or simultaneously. For example, if the first sensing component 501 includes a proximity sensor, it can first detect whether a spherical object is approaching within the containment space, and then activate the second sensing component 502, such as a physiological sensor, for detection. The control unit 52 is configured to determine that the user's head is located within the containment space when a spherical object is detected within the containment space and the object is a living organism.

[0088] The control components of the head-mounted device disclosed herein can effectively prevent transcranial light emitted when the light application module is improperly turned on from causing harm to the user, operator, or third party.

[0089] In some embodiments, the first set of sensing components and the second set of sensing components are of the same type. Specifically, when the first set of sensing components and the second set of sensing components are of the same type, multiple, such as multiple physiological sensors, can be arranged inside the head-mounted device, and each physiological sensor is distributed on a different head area. In this way, the signals from each physiological sensor can be used to simultaneously determine whether the object in the containment space is a spherical object and whether the object is a living organism.

[0090] In some embodiments, the first set of sensing components includes a pressure sensor disposed on the inner side of the head-mounted device relative to the top of the head, and the second set of sensing components includes a physiological sensor disposed on the inner side of the head-mounted device at a position that can contact the scalp, such as the forehead where no hair grows, so as to obtain a better physiological signal. The pressure sensor is used to detect whether an object is worn on the top of the head-mounted device. When it is determined that an object is worn on the top of the head-mounted device and the signal collected by the physiological sensor meets the preset standard, it can be determined that the head-mounted device is worn on the user's head. In this way, the determination of the user's head is achieved through two sensors, which consumes less resources.

[0091] This embodiment also provides a head phototherapy device, including a head-mounted device and a control component for the head-mounted device as described in the above embodiments. It is understood that this head phototherapy device can be a transcranial photomodulation device used to treat brain diseases, such as Alzheimer's disease, depression, and autism.

[0092] In addition to phototherapy products, the solution in this embodiment can also be used for brain scanning imaging or similar head light application products.

[0093] The head phototherapy device disclosed herein uses at least two detection methods to determine that the user's head is within the receiving space of the head-mounted device before controlling the unlocking or activation of the light application module. This can prevent transcranial light emitted when the light application module is improperly activated from causing harm to the user, thereby improving the safety of the device.
