[0002] Current human-computer interaction includes light interaction, sound interaction, and vibration interaction. Light interaction relies on visual information reception; in scenarios requiring high concentration, such as running or cycling, frequent screen checks can be distracting and pose safety hazards. Sound interaction relies on hearing and is easily affected by the environment, making it difficult to hear commands clearly in noisy environments. Furthermore, sound interaction can cause noise in public places and offers poor privacy. While vibration interaction does not present privacy issues, its limited feedback method cannot accurately convey interactive information. Summary of the Invention

[0028] To enable those skilled in the art to better understand the technical solutions of this disclosure, the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0029] The present disclosure will be described more fully below with reference to the accompanying drawings; however, the embodiments shown may be embodied in different forms, and the present disclosure should not be construed as limited to the embodiments set forth below. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of the disclosure.

It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning, unless expressly so defined in this disclosure.

[0034] This disclosure is not limited to the embodiments shown in the accompanying drawings, but includes modifications to the configuration based on the manufacturing process. Therefore, the areas illustrated in the drawings are schematic, and the shapes of the areas shown illustrate specific shapes of the areas of an element, but are not intended to be limiting.

[0035] In a first aspect, embodiments of this disclosure provide a non-contact human-computer interaction method based on micro-airflow sensing. This non-contact human-computer interaction method based on micro-airflow sensing can be executed by a non-contact human-computer interaction device based on micro-airflow sensing installed on a user terminal. Figure 1 This diagram illustrates the architecture of a non-contact human-computer interaction device based on micro-airflow sensing, according to an embodiment of this disclosure. Figure 1 As shown, the architecture of the non-contact human-computer interaction device based on micro-airflow sensing includes a sensing layer 10, an interaction layer 20, an airflow control layer 30, a user experience layer 40, and a current control layer 50. The sensing layer 10 is used to trigger interaction commands, such as sensing the position of the user device and triggering interaction commands when necessary based on the position of the user device.

[0036] The interaction layer 20 includes a main control chip 21 and a main drive module 22. The main control chip 21 is used to parse the interaction instructions and transmit the parsing results to the main drive module 22. The main drive module 22 generates an electrical signal based on the parsing results. This electrical signal is a signal that can be recognized by devices such as airflow generating components and duct selection switches.

[0037] The airflow control layer 30 includes a fan motor 31 and an air duct selection switch 32. The fan motor 31 generates micro-airflow and controls the airflow intensity based on the electrical signal output by the main drive module 22. Airflow intensity refers to the airflow velocity; the higher the velocity, the stronger the airflow, and vice versa. The airflow intensity can be set by the user, for example, to 3-8 m / s, a range where the airflow intensity is most easily perceived and does not cause discomfort. The airflow intensity can be set to low, medium, and high according to the user's perception. The airflow intensity can be adjusted by controlling the voltage input to the fan motor 31 or the duty cycle of its operation. In this embodiment, the fan motor 31 can be a fan, such as a "micro fan," with a thickness less than or equal to 3 mm and a diameter less than or equal to 20 mm.

[0038] The air duct selection switch 32 is used to control the airflow direction, airflow frequency, and airflow duration. Airflow direction refers to the direction of the airflow jet, airflow frequency refers to the number of periodic changes in airflow per unit time, and airflow duration refers to the duration of the airflow jet. The duration of a single airflow jet can be set to 0.1-2 seconds, such as 0.3 seconds, 0.5 seconds, and 1 second. The user equipment can be configured with multiple air ducts, each capable of delivering airflow in different directions. The air duct inlet is connected to the outlet of the fan motor 31, and the air duct outlet is equipped with an airflow nozzle. The airflow nozzle helps shape the airflow, improving the user's ability to perceive the airflow. The airflow nozzle can be customized according to the user's preferences.

[0039] The duct selection switch 32 is used to control the flow of air within the duct. At least one duct selection switch 32 is provided for each duct. When the duct selection switch 32 is open, airflow passes through the duct and exits from the corresponding airflow nozzle. The opening and closing of the duct selection switch 32 can be controlled by an electrical signal output from the main drive module 22. The duct selection switch 32 is open when powered on and closed when powered off. When the duct selection switch 32 is open, airflow is ejected from the duct corresponding to that duct selection switch 32. When the duct selection switch 32 is closed, airflow ejection stops from the duct corresponding to that duct selection switch 32. In some embodiments, the duct selection switch 32 includes, but is not limited to, an electromagnetic switch; the electromagnetic switch is open when powered on and closed when powered off.

[0040] The duct selection switch 32 can be a miniature electromagnetic switch. When the miniature electromagnetic switch is energized, the electromagnet in the miniature electromagnetic switch generates a repulsive force, which pushes the damper in the duct selection switch to open. When the miniature electromagnetic switch is de-energized, the electromagnet in the miniature electromagnetic switch generates an attractive force, which pushes the damper in the duct selection switch to close.

[0041] In User Experience Layer 40, the user's skin can sense airflow, obtain interactive information, and thus provide corresponding feedback. Users can perceive any one or different combinations of airflow intensity, direction, frequency, and duration. For example, combinations that users can perceive include, but are not limited to, a single short gust, multiple short gusts, a single long gust, and alternating long and short gusts. By adjusting any one or different combinations of airflow intensity, direction, frequency, and duration, different interactive information can be conveyed. For example, during navigation, airflow direction can be used to notify the user to move forward, turn right, turn left, or turn around. Because airflow is sensed through the skin, users do not need to look at the screen, thus not distracting them and improving safety. Airflow is not easily perceived by others, preventing information disclosure and improving the privacy of interactive information.

[0042] The current control layer 50 is used to control the power supply to the fan motor 31 and the air duct selection switch 32, and to start a reset procedure when the application senses the stop confirmation signal from the user feedback, that is, to stop the power supply to the fan motor 31 and the air duct selection switch 32, so that the fan motor 31 stops generating micro airflow and closes all air duct selection switches 32.

[0043] In some embodiments, the current control layer 50 includes a power management chip (PMIC) 51, which provides a stable and controllable power supply to the fan motor 31 and the air duct selection switch 32, ensuring normal hardware operation. When the user completes the interaction and it is detected by the application, a reset procedure is initiated. The main control chip 21 stops outputting PWM signals and cuts off the power supply to the fan motor 31 and the air duct selection switch 32 through the power management chip 51, causing the airflow to stop. After the airflow completely stops, an airflow stop signal is sent back to the interaction layer and the sensing layer, causing the application to mark the interaction as complete. The non-contact human-machine interaction device based on micro-airflow sensing returns to standby mode, thus completing the full closed-loop control from the execution of the interaction command to its stop.

[0044] In this embodiment, the user device includes, but is not limited to, mobile phones, watches, virtual reality headsets, glasses, controllers, etc. That is, a non-contact human-computer interaction device based on micro-airflow sensing can be set inside the user device, which can realize interactive information such as message reminders, navigation, games, immersive feedback, etc.

[0045] It should be noted that the micro-airflow in this embodiment refers to the airflow that can be perceived by the user, and is not a limitation on the intensity of the airflow.

[0046] Figure 2 A flowchart illustrating a non-contact human-computer interaction method based on micro-airflow sensing provided in an embodiment of this disclosure is shown. Figure 2 As shown, the non-contact human-computer interaction method based on micro-aerodynamic sensing includes:

[0047] Step S201: Respond to the first interactive command and generate the first electronic control signal.

[0048] The first interaction command can be initiated by an application in the user device. The application initiates the first interaction command when it determines that a pre-set triggering condition is met based on detection information. This embodiment does not limit the application or the criteria for determining whether the application initiates the first interaction command.

[0049] Step S202: Drive the airflow generating component based on the first electronic control signal to form a first airflow signal. The first airflow signal includes a micro-airflow with airflow direction, airflow intensity and / or airflow pattern.

[0050] In this embodiment, one or more combinations of airflow direction, airflow intensity, and airflow pattern correspond to specific interactive semantics, enabling users to perceive interactive semantics based on skin touch without touching the device display interface. The airflow pattern includes, but is not limited to, airflow frequency and the duration of each airflow jet.

[0051] In this embodiment, both the first airflow signal and the second airflow signal (hereinafter referred to as the second airflow signal) are signals that transmit information to the user through airflow. The user can perceive the airflow direction, airflow intensity, airflow pattern, etc. in the first and second airflow signals to obtain interactive commands.

[0052] Users perform corresponding actions based on the perceived first airflow signal. For example, in a navigation application, the trigger condition is the user's device location. When the navigation application determines that a right turn is needed based on the user's current location, it initiates a first interactive command instructing "turn right." A non-contact human-computer interaction device based on micro-airflow sensing generates a first electronic control signal based on the first interactive command, and drives an airflow generating component to form a first airflow signal based on the first electronic control signal. After the user perceives the first airflow signal, they turn left. As another example, in a game application, the trigger condition is that a game opponent enters the virtual character's field of vision. When the game application determines that an opponent has entered the virtual character's field of vision based on the game's virtual character and scene, it initiates a first interactive command instructing "shoot." A non-contact human-computer interaction device based on micro-airflow sensing generates a first electronic control signal based on the first interactive command, and drives an airflow generating component to form a first airflow signal based on the first electronic control signal. After the user perceives the first airflow signal, they can perform actions such as shooting or dodging.

[0053] The non-contact human-computer interaction method based on micro-airflow sensing in this embodiment responds to a first interaction command, generates a first electronic control signal, and drives an airflow generating component based on the first electronic control signal to form a first airflow signal. Users can perceive interactive semantics through the first airflow signal without touching the device's display interface. Compared to sound and light interaction, airflow interaction is less likely to disclose interaction commands to others in public places, offering better privacy. Moreover, the first airflow signal includes micro-airflow with airflow direction, airflow intensity, and / or airflow pattern. One or more combinations of airflow direction, airflow intensity, and airflow pattern can form different interactive semantics, providing more interactive dimensions than vibration interaction and enabling more accurate transmission of interactive information to the user, thereby improving the accuracy of human-computer interaction.

[0054] In some embodiments, generating a first electronic control signal in response to a first interactive instruction includes: parsing the first interactive instruction to obtain a first instruction parsing result; generating a first electronic control signal based on the first instruction parsing result, wherein the first electronic control signal includes a first sub-signal and a second sub-signal, the first sub-signal being used to drive the fan motor speed to control the airflow intensity, and the second sub-signal being used to drive the duct selection switch to connect the duct corresponding to the target direction; wherein the fan motor is used to generate micro-airflow, and the duct selection switch includes electromagnetic valves disposed in different ducts, and the directional injection of airflow is achieved by controlling the opening and closing of different electromagnetic valves.

[0055] This embodiment does not limit the specific form of the first interaction instruction. For example, the first interaction instruction can use structured data, such as key-value pairs. For instance, taking the "turn left" interaction instruction triggered by a navigation application as an example, the actual generated data can be {"action": "turn_left", "intensity": "medium"} (action = turn left, intensity = medium). The navigation application passes the "turn left" interaction instruction to the instruction interface (API). The instruction interface converts the "turn left, medium intensity" instruction into a digital / binary "machine code instruction," then packages the "machine code instruction" into a standardized binary data packet, and then passes it to the interaction layer via the bus.

[0056] This embodiment does not limit the parsing method of the first interactive command. By parsing the first interactive command, the interactive information transmitted to the user by the non-contact human-computer interaction device based on micro-airflow sensing can be obtained, and then the interactive information is transmitted to the user through airflow.

[0057] After receiving the first interaction instruction, the interaction layer first parses the first interaction instruction to obtain the first instruction parsing result. Then, through "internal instruction code + register assignment / function call", the first instruction parsing result is passed to the main drive module. The main drive module generates the first electronic control signal based on the first instruction parsing result. Under the control of the first sub-signal, the airflow generating component drives the fan motor speed to control the airflow intensity. Under the control of the second sub-signal, the air duct selection switch connects the air duct in the target direction, generating a micro-airflow in the target direction. That is, the airflow direction is controlled by the air duct selection switch.

[0058] In some embodiments, the first interaction command carries information such as airflow direction, airflow intensity, and / or airflow mode. When the interaction layer converts the airflow direction, airflow intensity, and / or airflow mode into a first electronic control signal, the first electronic control signal can also transmit the airflow direction, airflow intensity, and / or airflow mode information to the airflow control layer. The airflow control layer drives the airflow generating component to generate a first airflow signal based on the first electronic control signal. The airflow direction information includes, but is not limited to, left turn / right turn / forward / backward, and can be implemented through a duct selection switch. The airflow intensity information includes, but is not limited to, weak / medium / strong information. The airflow mode includes, but is not limited to, airflow frequency and the injection time of each airflow.

[0059] In some embodiments, the first control signal generated by the main drive module can be a pulse width modulation (PWM) signal. This form of first control signal can achieve rapid switching of low-voltage DC power, which helps to improve control accuracy. The PWM signal can control the airflow frequency and the opening and closing of the duct selection switch through the duty cycle.

[0060] An airflow generating component produces a micro-airflow by rotating a fan motor. The fan motor converts electrical energy into magnetic energy, and then from magnetic energy into mechanical energy. The airflow intensity is controlled by adjusting the duty cycle of a PWM (Pulse Width Modulation) signal. The airflow intensity depends on the fan motor speed, which in turn depends on the PWM duty cycle. A larger PWM duty cycle means a longer on-time, resulting in a faster fan motor speed and a stronger airflow. For example, when the PWM duty cycle is 0.3, the fan motor is on for 30% of the time and off for 70%, producing a weak airflow, also known as a weak breeze. When the PWM duty cycle is 0.7, the fan motor is on for 70% of the time and off for 30%, producing a stronger airflow, also known as a strong breeze. By adjusting the PWM duty cycle, the airflow intensity can be precisely controlled.

[0061] In this embodiment, airflow nozzles are provided at different locations on the user equipment, with at least one airflow nozzle in each direction. Each airflow nozzle is connected to the injection port of the airflow generating component via its corresponding air duct. Each air duct corresponds to a separate air duct selection switch, which controls the airflow nozzle's airflow output. For example, the user equipment is equipped with a left airflow nozzle, a right airflow nozzle, a front airflow nozzle, and a rear airflow nozzle. The left airflow nozzle is located at the second end of the left air duct, and the first end of the left air duct is connected to the injection port of the airflow generating component. The right airflow nozzle is located at the second end of the right air duct, and the first end of the right air duct is connected to the injection port of the airflow generating component. The front airflow nozzle is located at the second end of the front air duct, and the first end of the front air duct is connected to the injection port of the airflow generating component. The rear airflow nozzle is located at the second end of the rear air duct, and the first end of the rear air duct is connected to the injection port of the airflow generating component.

[0062] Because airflow is easily affected by the environment, it can impact a user's ability to perceive the first airflow signal. In some embodiments, the first electronic control signal also needs to be adapted to the environment. Therefore, the first airflow signal must consider not only the first interaction command but also the current scenario.

[0063] Here, "current scenario" refers to the environment in which the user device is currently located, including indoor and outdoor environments. This embodiment uses indoor and outdoor environments as examples. If the current scenario is outdoor, the skin's ability to sense the first airflow signal decreases; therefore, the airflow intensity of the first airflow signal can be increased. If the current scenario is indoors, the skin's ability to sense the first airflow signal is enhanced; therefore, the airflow intensity of the first airflow signal can be decreased.

[0064] In some embodiments, a built-in first sensor perceives the current scene and generates scene information based on the current scene. This scene information is information that affects the user's ability to perceive airflow. For example, the first sensor may include one of a wind speed sensor, a gyroscope, and a positioning system. The environment in which the user device is located is determined based on the information detected by the first sensor. For instance, a wind speed sensor measures ambient wind speed information, and the ambient wind speed information is used to determine whether the user device is indoors or outdoors. Alternatively, a positioning system can be used to determine the location of the user device, and then the location of the user device can be used to determine whether the user device is indoors or outdoors.

[0065] In some embodiments, generating a first airflow signal in response to a first interaction command includes: generating a first electronic control signal based on the first interaction command and scene information in response to the first interaction command.

[0066] The first interactive instruction is parsed to obtain the first instruction parsing result; and a first electronic control signal is generated based on the first instruction parsing result and scene information. The first sub-signal in the first electronic control signal is used to drive the fan motor speed to control the airflow intensity, and the second sub-signal is used to drive the duct selection switch to connect the duct in the corresponding target direction.

[0067] This embodiment generates scene information adapted to the current scene based on the current scene, generates a first electronic control signal by combining the first instruction parsing result and the scene information, and then drives the airflow generating component to form a first airflow signal based on the first electronic control signal. This can improve the adaptability of the first airflow signal to the environment, thus effectively reducing the impact of the environment on the user's perception ability, thereby improving the human-computer interaction experience.

[0068] In some embodiments, after generating a first airflow signal in response to a first interactive instruction, the method further includes: monitoring the user's limb movements or operational behavior in real time using a built-in second sensor; determining that the first interactive instruction is completed when the user's limb movements or operational behavior match the interactive semantics corresponding to the first airflow signal; and generating a second electronic control signal in response to determining that the first interactive instruction is completed, controlling the airflow generating component to stop ejecting airflow. The second electronic control signal includes a third sub-signal and a fourth sub-signal. The third sub-signal is used to control the speed of the fan motor, and the fourth sub-signal drives the duct selection switch to close the duct to stop the ejection of airflow.

[0069] The second sensor includes, but is not limited to, a camera, microphone, gyroscope, noise sensor, accelerometer, and positioning system, used to monitor the user's body movements or operational behaviors in real time. The camera detects the user's body movements, and the microphone detects the user's voice information. The gyroscope detects the user device's turning angle, the noise sensor detects ambient noise, the positioning system detects the user device's position, and the accelerometer detects the user device's speed. For example, using a gyroscope, if the first interaction command is a left turn command, and the gyroscope detects that the user device has turned left, then the first interaction command is considered complete. Similarly, if the feedback action is a click action, and the first interaction command is a shooting command, if the touchscreen or a designated area of ​​the touchscreen is detected to have been clicked, it indicates that the shooting command has been executed, and the first interaction command is considered complete. Power can then be stopped to the airflow generating component and the airflow selection switch, thereby stopping the airflow jet.

[0070] In some embodiments, the non-contact human-computer interaction method based on micro-airflow sensing further includes: generating an airflow stop confirmation signal when the airflow stops being detected; and resuming the standby state in response to the airflow stop confirmation signal.

[0071] In this embodiment, the operation status of the airflow generating component and the status of the duct selection switch can be directly monitored to determine whether the airflow has stopped spraying. Alternatively, the monitoring results of the airflow sensor installed in the duct can be used to determine whether the airflow has stopped spraying.

[0072] The standby state refers to the state after the information interaction between the non-contact human-machine interaction device based on micro-airflow sensing and the user has been completed, and the device resumes its standby state after determining whether the triggering conditions are met. When the airflow stops being emitted, an airflow stop confirmation signal is generated, and the non-contact human-machine interaction device based on micro-airflow sensing responds to the airflow stop confirmation signal and resumes the standby state.

[0073] In this embodiment, the non-contact human-computer interaction device based on micro-aerodynamic sensing can operate in different modes, including one or more of the following: disability mode, grip mode, navigation mode, game mode, and driving mode. The non-contact human-computer interaction device based on micro-aerodynamic sensing can switch between different modes according to the user's needs.

[0074] In some embodiments, in response to a mode switching command, the operating mode of the non-contact human-machine interaction device based on micro-airflow sensing is switched to a target mode, and the operating mode corresponds to the first electronic control signal.

[0075] For example, in response to the user's mode switching command, the operating mode of the non-contact human-machine interaction device based on micro-airflow sensing is switched to the disability mode, and a first interaction command is transmitted to the user according to the pre-set correspondence between the operating mode and the first electronic control signal.

[0076] In disabled mode, users can wear the non-contact human-computer interaction device based on micro-airflow sensing in appropriate positions according to their own needs. The device can be worn on the arm, wrist, neck, etc. Since different body parts have different sensing capabilities, in this embodiment, the operating mode corresponds to the first airflow signal. The first airflow signal is controlled by a first electronic control signal; therefore, the operating mode corresponds to the first electronic control signal. For example, as... Figure 3 As shown, the non-contact human-computer interaction device based on micro-airflow sensing is worn on the left arm. Since the arm's sensing ability is relatively weak, the airflow intensity of the first airflow signal can be increased.

[0077] In some embodiments, the first airflow signal and the first interaction command have a mapping relationship, which includes: the left airflow corresponds to the left turn command, the right airflow corresponds to the right turn command, the high-frequency airflow corresponds to the emergency reminder, and the low-frequency airflow corresponds to the notification message; or, the left airflow corresponds to the left dodge command, the right airflow corresponds to the right dodge command, the high-frequency airflow corresponds to shooting or throwing grenades, and the low-frequency airflow corresponds to the notification message.

[0078] For example, such as Figure 4 As shown, in a navigation scenario, the airflow on the left instructs the user to turn left, and the airflow on the right instructs the user to turn right. When the user deviates from the navigation route, a high-frequency airflow is used to alert the user of the deviation. When the destination is reached, a low-frequency airflow is used to notify the user.

[0079] For example, such as Figure 5 As shown, in an e-sports game scenario, the airflow on the left instructs the user to dodge to the left, the airflow on the right instructs the user to dodge to the right, the high-frequency airflow instructs the user to shoot, and the low-frequency airflow can notify the user when the game ends.

[0080] In some embodiments, the method further includes: generating a second airflow signal when the built-in third sensor sensing device is in a fall state, the second airflow signal being a continuous jet of airflow in all directions at maximum intensity.

[0081] In this embodiment, the drop sensing signal can be detected by sensors such as a gyroscope. When the user device is a mobile phone or smartwatch, the gyroscope is a built-in hardware device of the mobile phone, and the built-in gyroscope of the mobile phone can be used without additional settings, which not only reduces costs but also reduces the space occupied.

[0082] The sensing layer determines whether the user equipment is in a fall state based on the gyroscope's detection information. If it is, it generates a fall command and sends it to the interaction layer. The interaction layer parses the fall command and sends the parsing result to the main drive module. The main drive module generates an electrical signal based on the parsing result. The airflow control layer uses this electrical signal to control the airflow generating component to activate and all duct selection switches to open, generating a second airflow signal. All airflow nozzles spray air at maximum airflow intensity. When the accelerometer detects a sudden increase in acceleration, it indicates that the user equipment has landed. The sensing layer determines that the user equipment has landed based on the accelerometer data, generates an airflow stop command, and sends it to the interaction layer. The interaction layer parses the airflow stop command and sends the parsing result to the main drive module. The main drive module generates an electrical signal based on the parsing result, and the airflow control layer uses this electrical signal to control the airflow generating component and duct selection switches to close.

[0083] In city streets, users move among skyscrapers amidst various forms of noise, light, and electricity pollution. Wearing the non-contact human-computer interaction device based on micro-airflow sensing provided in this embodiment, users can interact with the device while walking, relying on airflow, unaffected by the environment and without being distracted by looking at their phones.

[0084] In e-sports games, users are focused on watching the enemy on the screen, listening to the footsteps, and using airflow interaction to indicate movement direction and avoid opponents. These multiple dimensions do not interfere with each other. In immersive VR movie viewing scenarios, micro-airflow interaction prompts can make users feel truly immersed in the game.

[0085] In industrial operations, users are busy moving goods. Head-mounted or wrist-worn devices guide users to designated shelves to retrieve items based on airflow indicators. Airflow prompts ensure that users move at the safest working speed, improving work efficiency.

[0086] Secondly, embodiments of this disclosure provide a non-contact human-computer interaction device based on micro-airflow sensing.

[0087] Figure 6 A schematic diagram of a non-contact human-computer interaction device based on micro-airflow sensing, according to an embodiment of this disclosure, is shown. Figure 6 As shown, this disclosure provides a non-contact human-computer interaction device based on micro-airflow sensing, comprising: an application module 11 and an airflow generating component 300, wherein,

[0088] Application module 11 is used to trigger a first interaction command. The first interaction command can be initiated by an application in the user device. The application initiates the first interaction command when it determines, based on detection information, that a pre-set triggering condition is met.

[0089] The airflow generating component 300 is used to generate a first electronic control signal in response to a first interactive command.

[0090] The airflow generating component 300 includes a fan motor 31 and an air duct selection switch 32. The fan motor 31 is used to control the airflow intensity and airflow mode in response to a first electronic control signal. The air duct selection switch 32 is disposed in the air duct and is used to control the airflow direction in response to the first electronic control signal. One or more combinations of airflow direction, airflow intensity and airflow mode correspond to specific interactive semantics, so that the user can perform corresponding actions based on the first airflow signal without touching the device display interface, based on the interactive semantics perceived by the skin.

[0091] The non-contact human-computer interaction device based on micro-airflow sensing in this embodiment of the present disclosure includes an application module for triggering a first interaction command. An airflow generating component responds to the first interaction command, generates a first electronic control signal, and drives the airflow generating component based on the first electronic control signal to form a first airflow signal. Users can perceive interactive semantics through the first airflow signal without touching the device's display interface. Compared to sound and light interaction, airflow interaction is less likely to disclose interactive commands to others in public places, offering better privacy. Furthermore, the first airflow signal includes micro-airflow with airflow direction, airflow intensity, and / or airflow pattern. One or more combinations of airflow direction, airflow intensity, and airflow pattern can form different interactive semantics, providing more interactive dimensions than vibration interaction and enabling more accurate transmission of interactive information to the user, thereby improving the accuracy of human-computer interaction.

[0092] In some embodiments, the non-contact human-machine interface device based on micro-airflow sensing further includes an instruction interface 60 for transmitting a first interactive instruction triggered by the application module 11 to the airflow generating component 300. This embodiment does not limit the type of instruction interface 60; any interface capable of transmitting interactive instructions can be used.

[0093] In some embodiments, the airflow generating assembly 300 further includes:

[0094] The main control chip 21 and the signal output terminal of the application module 11 are electrically connected to the input terminal of the main control chip 21. The main control chip 21 is used to parse the first interactive instruction and obtain the first instruction parsing result.

[0095] The main drive module 22 is connected to the input of the main control chip 21. The main drive module 22 is used to generate the first electronic control signal based on the first instruction parsing result.

[0096] The output terminal of the main drive module 22 is electrically connected to the control terminal of the fan motor 31. The fan motor 31 is used to generate micro-airflow based on the first electronic control signal.

[0097] The air duct selection switch 32 is installed inside the air duct. The control terminal of the air duct selection switch 32 is electrically connected to the output terminal of the main drive module 22. The air duct selection switch 32 is used to open in response to the first electrical control signal. The first end of the air duct is connected to the injection port of the fan motor 31.

[0098] Airflow nozzle 33 is disposed at the second end of the air duct and is used to eject airflow from the air duct to generate a first airflow signal.

[0099] In some embodiments, the non-contact human-computer interaction device based on micro-airflow sensing further includes an environmental sensing module 34, used to sense the current scene and generate scene information based on the current scene. The current scene refers to the environment in which the user device is currently located, including indoor and outdoor environments, with outdoor environments further subdivided. This embodiment uses indoor and outdoor environments as examples. If the current scene is outdoor, the skin's ability to sense the first airflow signal decreases; therefore, the airflow intensity of the first airflow signal can be increased. If the current scene is indoor, the skin's ability to sense the first airflow signal is enhanced; therefore, the airflow intensity of the first airflow signal can be reduced.

[0100] In another embodiment, the airflow generating component includes:

[0101] The main control chip 21 and the signal output terminal of the application module 11 are electrically connected to the input terminal of the main control chip 21. The main control chip 21 is used to parse the first interactive instruction and obtain the first instruction parsing result.

[0102] The main drive module 22, the output terminal of the main control chip 21, the output terminal of the environmental perception module 34 are connected to the input terminal of the main drive module 22, and the main drive module 22 is used to generate the first electronic control signal based on the first instruction parsing result and scene information.

[0103] The output terminal of the main drive module 22 is electrically connected to the control terminal of the fan motor 31. The fan motor 31 is used to generate micro-airflow based on the first electronic control signal.

[0104] The air duct selection switch 32 is installed inside the air duct. The control terminal of the air duct selection switch 32 is electrically connected to the output terminal of the main drive module 22. The air duct selection switch 32 is used to open in response to the first electronic control signal. The first end of the air duct is connected to the injection port of the airflow generating component.

[0105] Airflow nozzle 33 is disposed at the second end of the air duct and is used to eject airflow to generate a first airflow signal.

[0106] In some embodiments, the user equipment includes a plurality of side frames, and an airflow nozzle 33 is disposed on at least one of the plurality of side frames.

[0107] Figure 7 A schematic diagram of the user equipment and a non-contact human-computer interaction device based on micro-airflow sensing is shown. Figure 7As shown, the mobile phone includes four side frames: a first side frame 41a, a second side frame 41b, a third side frame 41c, and a fourth side frame 41d. A first airflow nozzle 33a is provided on the first side frame 41a, and a second airflow nozzle 33b and a third airflow nozzle 33c are provided on the second side frame 41b. The second airflow nozzle 33b is located closer to the first side frame 41a, and the third airflow nozzle 33c is located closer to the third side frame 41c. A fourth airflow nozzle 33d is provided on the third side frame 41c, and a fifth airflow nozzle 33e and a sixth airflow nozzle 33f are provided on the fourth side frame 41d. The fifth airflow nozzle 33e is located closer to the first side frame 41a, and the sixth airflow nozzle 33f is located closer to the third side frame 41c.

[0108] In this embodiment, each airflow nozzle corresponds to an air duct and is located at the second end of the air duct. For example, the first airflow nozzle 33a is located at the second end of the first air duct 35a, the second airflow nozzle 33b is located at the second end of the second air duct 35b, the third airflow nozzle 33c is located at the second end of the third air duct 35c, the fourth airflow nozzle 33d is located at the second end of the fourth air duct 35d, the fifth airflow nozzle 33e is located at the second end of the fifth air duct 35e, and the sixth airflow nozzle 33f is located at the second end of the sixth air duct 35f. The first ends of the first air duct 35a, the second air duct 35b, the third air duct 35c, the fourth air duct 35d, the fifth air duct 35e, and the sixth air duct 35f are connected to the nozzles.

[0109] In this embodiment, all air ducts can share a single fan motor 31, or each air duct can have its own dedicated fan motor 31, meaning one fan motor 31 provides airflow to its corresponding air duct. When all air ducts share a single fan motor 31, the nozzle is connected to the input connector of a multi-connector, and each air duct is connected to an output connector. The fan motor 31 can be a "micro fan," which will not affect the size of the mobile phone or smartwatch.

[0110] In some embodiments, the air duct selection switch 32 is located near the injection port, that is, near the second end of the air duct. The air duct selection switch 32 can be an electromagnetic switch, which closes when power is off and opens when power is on.

[0111] Figure 8 A schematic diagram of the structure of an electromagnetic switch according to an embodiment of this disclosure is shown. Figure 9 A schematic diagram of an electromagnetic switch according to an embodiment of this disclosure is shown. (As follows) Figure 8 and Figure 9As shown, the electromagnetic switch includes a first pole 321 and a second pole 322. For example, the first pole 321 is a permanent magnet, such as the S pole of a permanent magnet. The second pole 322 is an electromagnet. When energized, the polarity of the second pole 322 is the S pole, and a repulsive force is generated between the first pole 321 and the second pole 322, thus opening the electromagnetic switch. When de-energized, the polarity of the second pole 322 disappears, and an attractive force is generated between the first pole 321 and the second pole 322, thus closing the electromagnetic switch. It should be noted that the polarity of the first pole 321 and the second pole 322 can also be the N pole, which can still control the opening and closing of the electromagnetic switch.

[0112] The on / off state of the electromagnetic switch can be controlled by the power supply S1, the switching transistor K, the capacitor C, and the main drive module 22. The power supply S1, the switching transistor K, and the capacitor C are connected in series. The main drive module 22 can be connected in series in this series circuit or placed outside this series circuit. The main drive module 22 is used to control the on / off state of the switching transistor K.

[0113] In some embodiments, an airflow nozzle is provided at the connection position of two adjacent side frames of the user equipment.

[0114] Figure 10 A schematic diagram of the structure of a mobile phone and a contactless human-computer interaction device based on micro-airflow sensing is shown in an embodiment of this disclosure. Figure 10 As shown, the airflow nozzle 33 is disposed at the connection position of two adjacent side frames, that is, the airflow nozzle 33 is disposed at the corner of the user device. In some embodiments, the airflow nozzle 33 can be disposed in more locations, such as at least one airflow nozzle 33 disposed in the middle of the side frame, or at least one airflow nozzle 33 disposed on the back of the phone.

[0115] In some embodiments, the user equipment further includes:

[0116] The third sensor 36 is used to sense the drop status of the user equipment and triggers a drop signal when the user equipment is detected to be in a drop state. The third sensor 36 includes, but is not limited to, a gyroscope and an accelerometer.

[0117] When the accelerometer detects a triaxial acceleration value close to 0, it indicates that the user equipment has fallen. Within 10 milliseconds, the main drive module energizes the airflow generator and the duct selection switch, causing the airflow nozzles to generate jets of air. The downward-facing airflow nozzle 33 sprays air downwards, generating an upward reaction force that can mitigate the impact of the fall, thus protecting the user equipment. Once the user equipment hits the ground, the acceleration value suddenly increases, and the main drive module de-energizes the airflow generator and the duct selection switch, stopping the airflow. This completes one protection cycle for the user equipment.

[0118] Application module 11 is also used to respond to a drop signal and generate an emergency command, which is used to cause all airflow nozzles to eject airflow.

[0119] The airflow generating assembly 300 is also used to respond to emergency commands by causing all airflow nozzles to eject airflow.

[0120] In some embodiments, the non-contact human-machine interaction device based on micro-airflow sensing further includes a monitoring module 37, used to confirm that the airflow has stopped spraying when the airflow generating component and the air duct selection switch are detected to be closed.

[0121] Application module 11 is also used to generate an airflow stop confirmation signal when the airflow stops spraying, and to restore the non-contact human-machine interaction device based on micro-airflow sensing to standby mode.

[0122] The following example uses a mobile game application. Different interactive commands are mapped to airflow signals, meaning different interactive commands are mapped to airflow directions. The first interactive command is transmitted to the main control chip via a command interface. The main control chip parses the first interactive command, and the main drive module converts the parsed result into a first electrical signal. The airflow generating component is activated under the action of the first electrical signal and generates micro-airflow. For example, such as... Figure 4 As shown, when the first interaction command is a left dodge command, the air duct selection switch corresponding to the airflow nozzle located on the first side frame (left side frame in the figure) is activated under the action of the first electrical signal, causing the airflow nozzle on the first side frame to spray airflow. The user perceives airflow on the left and performs a left dodge action. When the first interaction command is a right dodge command, the air duct selection switch corresponding to the airflow nozzle located on the third side frame (right side frame in the figure) is activated under the action of the first electrical signal, causing the airflow nozzle on the third side frame to spray airflow. The user perceives airflow on the right side frame and performs a right dodge action. When the first interaction command is a shoot (fire) command, the air duct selection switches corresponding to the airflow nozzles located on the first side frame, second side frame (bottom side frame in the figure), third side frame, and fourth side frame (top side frame in the figure) are activated under the action of the first electrical signal, causing the airflow nozzles on the first side frame, second side frame, third side frame, and fourth side frame to spray airflow. When the user perceives airflow from all airflow nozzles, they perform a shoot action.

[0123] The following example uses a navigation application on a smartwatch. Different interaction commands are mapped to airflow signals; that is, different interaction commands are mapped to airflow directions. For example... Figure 4As shown, when the first interactive command is a left turn command, the air duct selection switch corresponding to the airflow nozzle located on the first side frame (left side frame in the figure) is activated under the action of the first electrical signal, causing the airflow nozzle on the first side frame to spray airflow. The user senses the airflow on the left side frame and performs a left turn. When the first interactive command is a straight-ahead command, the air duct selection switch corresponding to the airflow nozzle located on the fourth side frame (upper side frame in the figure) is activated under the action of the first electrical signal, causing the airflow nozzle on the first side frame to spray airflow. The user senses the airflow on the first side frame and performs a straight-ahead command. When the first interactive command is an arrival command, the air duct selection switches corresponding to the airflow nozzles located on the first side frame, second side frame (lower side frame in the figure), third side frame (right side frame in the figure), and fourth side frame are activated under the action of the first electrical signal, causing the airflow nozzles on the first side frame, second side frame, third side frame, and fourth side frame to spray airflow. When the user senses airflow from all airflow nozzles, they can use a button to provide feedback to the non-contact human-machine interaction device based on micro-airflow sensing that they understand this is the destination.

[0124] It should be noted that the maximum difference in travel between the various air ducts in the micro-airflow sensing-based non-contact human-machine interface device is 200mm. With an airflow speed of 3-8m / s, the delay between different air ducts is approximately 40 milliseconds, which is imperceptible to the user. From the moment the first interaction command is received, the reaction time of the airflow generating component and the air duct selection switch in the micro-airflow sensing-based non-contact human-machine interface device is only 20 milliseconds. Human perception time is between 200-250 milliseconds, meaning the feedback time of the micro-airflow sensing-based non-contact human-machine interface device is far shorter than human reaction time. The noise generated by the airflow generating component is approximately 32-48dB, within the acceptable range for daily use. The power consumption of the airflow generating component is 40 milliwatts at low speeds, and the maximum power consumption can be controlled within 135 milliwatts, both within a manageable range.
