Description

Technical Field

[0001] This application relates to the field of devices, and more particularly, to systems and methods for controlling devices. Background Art

[0002] The following description includes information that may be helpful in understanding this application. Any information provided is not to be considered prior art or relevant to the presently claimed disclosure, or that any publication cited is prior art, either expressly or by implication.

[0003] As a respected iconic traditional appliance, ceiling fans have a rich history in enhancing human comfort and well-being in homes, workplaces, and various other environments. The control mechanisms of ceiling fans are rooted in tradition and have evolved over time. Initially, they were operated by a looping pull-cord system where each gentle tug on the cord extending down from the ceiling fan seamlessly switched the fan's speed in a sequential and cyclical manner, starting from a stationary state, transitioning to the "on" state, passing through one or more higher speeds, and then back to the stationary position, all through each successive virtual pull-cord gesture. In some cases, on the other side of the fan, another cord controlled the lighting fixture installed within the ceiling fan, and the user switched the light on and off via this cord.

[0004] With technological advancements, ceiling fans have adopted new control methods. Basic wall switches with binary states enable users to switch between "on" and "off", simplifying operation. Additionally, more sophisticated "ceiling fan speed" selector wall switches provide a range of intermediate speed options. Innovations such as remote control devices, voice-controlled interfaces, and digital mobile and computer applications have seamlessly integrated into the field of ceiling fan control methods.

[0005] The scenarios of ceiling fan control are diverse and adaptable, not limited to a single method, and its flourishing depends on the integration of various methods that can coexist harmoniously. Depending on the complexity of the product design and user preferences, these combinations of control technologies can be seamlessly integrated into a single ceiling fan.

[0006] The above-mentioned ceiling fan control methods all have certain drawbacks. For example, the following control methods: Rope / chain ("wire") control: A significant limitation of rope control is its limited accessibility. Users often encounter difficulties in operating the control wire, especially when the ceiling fan is located above a bed or large furniture, which usually requires climbing onto the bed or rearranging large items, thus causing inconvenience and potential safety risks. In addition, people with limited mobility, such as the elderly or physically disabled, or those sleeping and waking up in bed, face significant barriers in using this method to reach the ceiling fan. Moreover, when people are sitting comfortably with the ceiling fan running, changing the ceiling fan speed requires interrupting ongoing activities, thus causing unnecessary inconvenience to the user.

[0007] Remote control: While remote control offers convenience, it also has certain limitations. A key challenge is that remote control devices are often misplaced. When trying to manage a ceiling fan, this can result in frustrating time losses and increased annoyance. This inconvenience is particularly evident when used at night in bed, when the surrounding light is dim or completely dark. Searching for the remote control can cause disruptions, potentially waking a sleeping partner in the same bed or even a quiet baby in a nearby crib.

[0008] Voice activation: Despite its innovative approach, voice activation still has some limitations that need to be addressed. Not every voice command is suitable for multiple social situations. For example, using voice commands while sleeping with a partner at night may disrupt their sleep. Similarly, during a dinner with guests, issuing commands such as "Increase the ceiling fan speed" or "Turn off the ceiling fan" may seem inappropriate and divert attention from the ongoing engaging discussion. Additionally, if the microphone of the ceiling fan is seamlessly integrated into a network solution, there is a risk of privacy leakage, including external eavesdropping and potential fraudulent activities due to unauthorized microphone access.

[0009] Digital device ceiling fan control: Against the dynamic backdrop of the progress of smart homes and intelligent buildings, ceiling fans have adopted emerging network "smart" technologies, offering a range of remote functions, configurations, and scheduling options. However, due to the complexity of the settings, substantial installation work, and associated costs, the "smart" market mainly caters to early adopters and high-end users. Using such applications typically requires the physical presence of the user or manual operation of the ceiling fan through the device, thus magnifying the aforementioned limitations and drawbacks, especially those related to remote control commands. Moreover, a large number of ceiling fan users remain cautious about adopting "smart home" technologies, which has prompted the need for a more straightforward way to control ceiling fans. This approach would enable them to leverage the advantages of modern innovation and advanced software while retaining a simple and intuitive user experience, ensuring that they can benefit from modern technology without having to deal with potential complexities.

[0010] In summary, each of the methods mentioned for controlling ceiling fans presents challenges in terms of user convenience, accessibility, and applicability. Wired control can be inconvenient and unsafe, especially when used at night, as physical activities in the dark are undesirable and challenging. Remote control and voice activation may not always be available or appropriate, particularly in a night-time environment, and may disturb sleeping individuals or violate privacy. Additionally, digital control methods may be out of reach for many users as they often require a certain level of technical expertise and equipment, which not everyone possesses. These limitations are particularly evident in night-time situations where user comfort and ease of use are crucial.

[0011] Therefore, there is a need to improve the existing technology and provide innovative solutions. More specifically, there is a need for a simpler, more intuitive, and effective way to control a ceiling fan. Summary of the Invention

[0012] The present invention may not necessarily disclose all the features necessary for the content of this application. This application may exist in sub - combinations of the disclosed features. Various combinations and sub - combinations are fully described in specific embodiments.

[0013] A system for controlling a device through intuitive actions caused by human movement, which replaces current control methods and / or replicates or imitates legacy traditional methods of device triggering and / or similar movements. The system includes a detector configured to detect the presence of one or more users in a room. The detector module includes a communication module for transmitting the identified actions of the one or more users to a control module. These devices can be lighting fixtures, light bulbs, mirrors, vehicles, drones, televisions, laptops, furniture, machines, and air - conditioning equipment. A power module supplies power to the detector assembly, control assembly, and communication module attached to the device. The control assembly attached to the device is configured to control a ceiling fan based on detecting one or more actions from one or more users present in the room, where the one or more actions are similar to traditional gestures of a virtual pull cord or similar gestures. The switch of an integrated ceiling - fan light can also be performed using the other side of the center of the ceiling fan. Artificial intelligence algorithms are used to enhance action recognition and fan control.

[0014] In another embodiment, the sensor module is incorporated within or adjacent to the fan unit. The sensor module typically consists of sensors for detecting human presence and / or interpreting body movements. Additionally, the sensor module typically includes a control component configured to manage the fan based on user - friendly body movements, as further detailed below. For certain applications, communication is established between the control component and the control unit of the fan, using human presence and / or body - movement detection to transmit instructions to the control unit of the fan as a response. The fan can be a ceiling fan, wall - mounted fan, floor fan, table fan, etc.

[0015] The sensors themselves can take various forms, including cameras, UWB (Ultra - Wideband) detectors, millimeter - wave passive sensors, radar units, radar modules, radar devices, active millimeter - wave radar - on - chip (ROC), or any other radar - sensor type using similar technologies. These sensors are equipped with the necessary processing and communication functions to enable seamless interaction between the user, the sensor module, and the ceiling fan, thereby enabling intuitive and sensitive control of the fan's operation.

[0016] In some embodiments, an on-chip radar sensor module, referred to as the "radar module", is seamlessly integrated as a core component inside various types of fans. This radar module is at the core of the fan's electronic design and can be connected to existing fan and light control units, or in some cases, can completely replace traditional control elements.

[0017] Importantly, although often referred to in this specification as an on-chip radar (ROC), its technical scope encompasses any radar unit, radar module, radar device, or other radar sensor type using similar technologies, provided they are equipped with the necessary processing and communication capabilities.

[0018] The sensor module typically includes a control component configured to respond to intuitive body movements. These movements can be performed using the arm, hand, or other parts of the body. These movements act as triggers for specific fan operation commands, including functions such as turning the fan on / off, adjusting (increasing or decreasing) the fan speed, and enabling / disabling the fan light. Importantly, these movements are very intuitive, ensuring that users can easily perform these actions even when lying in bed in a dark room.

[0019] The control component is configured to recognize the gesture of the user virtually pulling the fan cord by identifying the downward pulling movement of the body, which is the same as the action of traditionally pulling an ordinary fan cord.

[0020] The control component is also configured to cyclically change the fan's rotation speed setting sequentially according to each virtual cord-pulling gesture: from a stationary state to an on state, then through one or more higher speeds, and finally returning to the stationary state with each subsequent virtual cord-pulling gesture.

[0021] For example, the control component can be set to rotate the fan in the same direction according to the user rotating their arm, hand, or other part of their body in a specific direction. Additionally, the fan speed can be adjusted to make the fan rotate faster or slower when the user changes the speed of their body movement. Further, when the user makes corresponding body movements in the opposite direction, the control component can also stop the fan from rotating.

[0022] This technology allows for user-friendly and intuitive interaction with the fan, enabling easy control of its various functions even under low-light or zero-light conditions, without the need for a physical remote control, mobile device, or voice commands. However, the gesture control of the fan can work simultaneously or in parallel with a remote control or other fan control devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the objectives, technical solutions and advantages of the present application clearer, the following clearly and completely describes the technical solutions of the present application with reference to the accompanying drawings of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0034] The present invention discloses a sensor module that is seamlessly integrated within or in close proximity to a fan unit. The sensor module plays a crucial role in enhancing the functionality, comfort, and user - friendliness of the fan. The sensors included in the sensor module are typically designed to perform two main functions: detecting human presence and detecting body movements. These functions are essential for achieving intuitive and responsive fan control. The sensors can identify whether there is a person in the room where the fan is installed, and this detection is valuable as it allows the fan to adjust its operation based on the presence or absence of a person, thereby saving energy when the room is unoccupied. Another key function of the sensors is the ability to identify the body movements of individuals in the room, which can include activities of the arms, hands, or other body parts. The fan can be a ceiling fan, a wall - mounted fan, a floor fan, a table fan, etc. For simplicity, many examples and embodiments relate to ceiling fans, but it should be clear that the examples and embodiments cover all types of fans.

[0035] Intuitive actions for device control are typically physical movements performed with the arms and hands that naturally mimic or symbolize the desired actions, movements, or mode changes of the device or apparatus. These actions are designed to be easy to remember and execute and generally resemble the physical operation or effect of the device they control. For example, 1. Ceiling fan startup: The arm makes a circular rotational movement, mimicking the rotation of the fan blades, to send a signal to the fan to turn on or off; 2. Light control: Opening the fingers towards the lamp turns the light on, and making a clenched fist towards the lamp turns the light off; 3. Blinds adjustment: Waving the hand upwards raises the blinds, and waving the hand downwards lowers the blinds. These gestures utilize the natural tendency to associate certain body movements of humans with specific actions, making them intuitive and easy to use in daily life.

[0036] In a particular application, an on-chip radar sensor module, commonly referred to as a "radar module", is integrated as part of a ceiling fan, regardless of the fan type. This radar module is typically a core component of the ceiling fan's electronic design and serves as the central element for interaction. The sensor module usually includes a control component that is responsible for interpreting the detected human presence and body movements and using the detected human presence and body movements to control the ceiling fan. The essence of this innovation lies in using intuitive body movements as a means to control the ceiling fan. These movements are carefully designed to be user-friendly and easily understandable by people in the room. A simple movement could be extending or retracting an arm or hand to turn the fan on or off. The fan speed can be adjusted by making a circular motion with an arm or hand, with a clockwise motion increasing the speed and a counterclockwise motion decreasing the speed. If the ceiling fan has an integrated light, gestures can be used to control its on / off function. One of the main advantages of this technology is that it is suitable for use at night. Even in a dark room, users can easily perform these intuitive gestures to control the ceiling fan. This eliminates the need to reach for a switch or fumble for a remote control, or illuminate a mobile device application, making it a highly practical solution for various scenarios.

[0037] Overall, the present invention changes the way users interact with their ceiling fans through a more intuitive, convenient, and user-friendly control method; improves energy efficiency by adjusting the fan operation according to the presence of people, and provides a practical solution for night use, ultimately enhancing the overall user experience.

[0038] The process of detecting and recognizing human actions is an integral part of the entire process of digital detection, classification, action recognition, and control state machine, involving several basic functions: Detection of radar echoes and 4D radar point clouds: The first key step in this innovative technology is the detection of radar echoes. When the radar module operates, it emits radio waves into the room, and then these waves are reflected back from various surfaces and objects within the radar coverage. When the waves return to the radar module, they carry valuable information. The system processes this data and generates what is called a 4D "radar point cloud". This cloud provides a comprehensive view of the room and all physical surfaces and objects within the room. Each point in this cloud is associated with specific spatial coordinates (x, y, z) and a radial velocity (Vr) relative to the radar module. This level of detail is crucial for accurately detecting human presence and actions.

[0039] Grouping of Detected Radar Points: After detecting radar echoes and establishing a 4D radar point cloud, the next step is to group these points into different entities ("targets"). This grouping process is crucial for distinguishing different objects within the radar coverage. Notably, it allows the system to classify and separate humans, pets, and other targets. For each group, the technology calculates the centroid, providing precise position coordinates (x, y, z) and the radial velocity relative to the position of the radar module. This data enables the system to track the movement of different objects indoors.

[0040] Classification: Once the radar points are grouped into targets, the system further processes this information by classifying it. This step is crucial as it helps the technology distinguish between detected humans, pets, and other objects. By classifying these groups, the system can specifically identify the presence of humans, which is a key component for controlling the ceiling fan based on occupancy. This classification forms the basis for subsequent human gesture recognition for fan and light control.

[0041] Human Gesture Recognition: The core of this technology lies in the ability to accurately recognize specific human gestures. These gestures are designed to provide users with an intuitive way to control the ceiling fan and its integrated light. The recognized gestures cover a wide range, including simple, intuitive, and easily recognizable actions.

[0042] Traditional ceiling fans rely on a tried-and-true control method called the loop pull cord system. In this system, a cord extends from the ceiling fan, and users interact with the cord by gently pulling it to adjust the fan's speed and turn the fan on or off. For years, this method has been the standard for controlling ceiling fans, providing a simple and intuitive way to manage the fan's operation. When a user initiates this control method, gently pulling the cord sequentially changes the ceiling fan's speed to different levels, which typically start from the stationary state where the fan is completely off, usually denoted as "0", and with each subsequent pull, the fan speed gradually increases, usually marked as "1", "2", etc., with larger numbers representing higher fan speeds, and the cycle continues until the user decides to return the fan to its initial "0" state, indicating that the fan is turned off. In some cases, especially in more advanced ceiling fan models, there may be a second cord on the other side of the fan. The second cord is responsible for controlling the integrated light within the ceiling fan. Just as the first cord affects the fan speed, pulling the second cord in a similar manner can turn the light on and off with each downward pull. This traditional control method has been familiar and reliable to users for years, but with the advancement of technology and the evolution of user preferences, there is an increasing interest in exploring more intuitive and modern ceiling fan control options, such as those based on gesture recognition and radar technology. These innovations aim to enhance user convenience and adapt to changing lifestyles and preferences.

[0043] The control component is configured to recognize a virtual pull cord gesture of the main body by identifying a downward pulling action of the main body, which is the same as the traditional pulling action of a conventional ceiling fan.

[0044] The control component is further configured to respond to each virtual pull cord gesture by cyclically changing the rotational speed of the ceiling fan from a stationary state to an on state in sequence, and then through one or more higher rotational speeds, and finally return to the stationary state with each subsequent virtual pull cord gesture.

[0045] Gestures include but are not limited to: a. Raise the arm towards the ceiling fan and perform a clockwise or counterclockwise rotation gesture, which is an intuitive control of the ceiling fan; b. Raise the arm towards the ceiling fan and perform a radial "tap" gesture towards or away from the fan, which is usually used to control the light of the fan; c. Raise the arm and perform a sliding gesture from right to left or from left to right; d. Raise the arm and perform a downward or upward vertical sliding gesture; e. Clap the hands one or more times with both arms raised in front of the ceiling fan; f. Raise the arm and make a signal with distinct digital fingers (one, two, three, four, or five fingers), and stay stationary in front of the ceiling fan for a period of time; g. Clench the fist in front of the ceiling fan; h. Recognize any other predefined human gestures allowed by the processing ability of the radar module; i. Recognize combinations of the above human gestures or combinations in a predefined sequence.

[0046] Recognition of traditional pull cord gestures: In addition to intuitive gestures, the technology of the present invention can also recognize gestures corresponding to traditional pull cord methods for controlling ceiling fans and lights, and this recognition allows users accustomed to traditional control mechanisms to make a seamless transition. By decomposing the process of the technology under a specific heading, it can be clearly seen that detecting and recognizing human gestures play a core role in creating an intuitive and user-friendly method for controlling ceiling fans and lights, ultimately enhancing the overall user experience.

[0047] In an embodiment of the present invention, the control component is designed to recognize virtual pull cord gestures made by a human user. These gestures closely resemble the action of pulling a physical cord, even when there is no actual cord present, and these gestures can occur at a distance from the location of a traditional physical cord relative to a ceiling fan. The main feature of these virtual pull cord gestures is their ability to mimic the familiar cord pulling action without the need for an actual physical cord. For example, a user may perform a gesture that appears as if they are pulling a cord, such as clenching their fist and performing a downward pulling motion. These intuitive gestures replicate the action of a physical pull cord, which has been a traditional method of controlling a ceiling fan for many years. These virtual gestures are designed to enhance the accessibility and convenience of ceiling fan control. Unlike traditional physical cords, users can perform these gestures from a variety of positions and distances. For example, if the fan is located above a table, the user can perform a virtual pull cord gesture from the side of the table. Similarly, even if there is a cord, the user can perform these gestures from a height lower than the height at which a physical cord typically extends. This approach makes the control of the ceiling fan more flexible and able to adapt to different room configurations and user preferences, eliminating the need for the user to physically interact with the cord and making the process more user-friendly, accessible, and convenient.

[0048] The virtual pull cord gestures are very similar to the traditional action of pulling a physical cord. These gestures are designed to be intuitive and easy for users to recognize. Some common examples of these virtual pull cord gestures include a user clenching their fist and a downward pulling motion. For example, a user may make a fist or simulate the action of pulling a cord downward. These gestures are intuitive and replicate the familiar physical pull cord action, which has been the standard method of controlling a ceiling fan for many years. By mimicking the traditional pull cord action, these virtual gestures provide a user-friendly and easily adaptable way to control a ceiling fan. Users can perform these intuitive gestures without the need for an actual physical cord, making the fan control process easier and more convenient.

[0049] In one aspect of the present invention, the control component is designed to respond to virtual pull cord gestures in a manner that closely mimics the process of controlling a traditional ceiling fan by pulling a physical cord. This means that the control component interprets these virtual gestures in a way that is similar to how the pulling action of a physical cord affects the fan. For example, when a user performs a virtual pull cord gesture, the control component sequentially and cyclically changes the rotational speed of the ceiling fan. The ceiling fan transitions from a stationary (off) state to an active (on) state based on the initial virtual pull cord gesture. With each subsequent virtual pull cord gesture, the control component increases the fan's rotational speed, gradually reaching one or more higher speeds, and finally, in response to another virtual pull cord gesture, the control component returns the fan to the stationary (off) state, thus completing the cyclic sequence. This approach replicates the familiar traditional ceiling fan control process where a user pulls a physical cord to turn on the fan, adjust its speed, and then turn off the fan again; however, in this case, the user can achieve the same control effect without using a physical cord, enhancing the convenience and accessibility of fan control.

[0050] In another aspect of the present invention, the control component can also control a ceiling fan light based on virtual pull cord gestures that mimic controlling a traditional fan light by pulling a second cord. This operation is similar to using a second cord to control a traditional ceiling fan with a light. The user performs a virtual pull cord gesture on one side of the ceiling fan to control the fan's speed as described in the previous section; based on the user performing a virtual pull cord gesture on the other side of the ceiling fan, the control component is programmed to control the ceiling fan light. Each virtual pull cord gesture on the second side of the fan causes the control component to turn the light on and off sequentially, similar to the operation of a traditional ceiling fan light controlled by a second cord. This method allows the user to control the fan's speed and light using intuitive virtual pull cord gestures. It replicates the traditional fan control experience while eliminating the need for physical cords, improving user convenience and accessibility.

[0051] The implementation of virtual pull - cord gestures provides a more accessible, convenient, and safer way to control a ceiling fan while retaining the familiar and intuitive user experience of traditional control methods. Since the concept of controlling a ceiling fan with a pull - cord has been deeply ingrained in people's collective experience for decades, virtual pull - cord gestures are highly intuitive. Users can easily master and adopt this method of controlling the fan, thus obtaining a familiar and comfortable experience. Virtual pull - cord gestures eliminate the need for a physical cord. Users do not need to hold or touch the actual cord, providing a cleaner and more streamlined aesthetic for the ceiling fan. This also eliminates the potential wear and tear on the physical cord. Users can perform these virtual gestures at a certain distance from the fan and even when not directly beneath the fan. When the fan is located above a table or on a high ceiling, the added convenience of virtual pull - cord gestures is particularly valuable and eliminates the need to balance or stand on furniture to reach the pull - cord. The present invention does not require the use of a physical cord and can control the fan from a distance, which improves safety as users do not need to take dangerous actions (such as standing on a bed, stool, or chair) to contact and operate the physical cord, reducing the risk of accidents and injuries associated with traditional pull - cord methods.

[0052] The ceiling fan control method of the present invention employs artificial intelligence (AI) algorithms, representing an advanced approach to enhancing the user experience and energy efficiency. In some applications, the ceiling fan control system utilizes artificial intelligence algorithms that are designed to make the operation of the fan more intelligent and adaptive. The artificial intelligence analyzes data from sensors and user behavior to optimize the speed and operation of the fan, ensuring comfort and energy efficiency. The sensors of the ceiling fan (such as including a radar module) can detect the presence of people in the room and classify them. This ensures that the fan can respond specifically to the presence of humans, differentiating humans from other entities such as pets. One of the main functions of artificial intelligence (AI) in ceiling fan control is occupancy - based activation. The control component activates the ceiling fan only when one or more people are detected in the room. This function ensures that the fan operates when needed and shuts off when the room is unoccupied; when it is detected that the room is unoccupied, the ceiling fan and / or its built - in lighting are turned off, which is an important energy - saving function; when there is no one in the room, this function can prevent the unnecessary operation of the fan and consumption of electricity; this not only saves energy but also extends the service life of the fan.

[0053] The following several installation embodiments of adding a radar module in the ceiling fan application are to adapt to various settings and preferences: Separate radar module: In the first embodiment, the radar module is an independent unit that includes all components and functions; this module typically has a downward - facing radar antenna and uses a communication channel to interact with the control unit of the fan.

[0054] Under - hood radar module: The second embodiment involves positioning the "front end" of the radar module, which includes the antenna and RF circuitry, under the hood; such a hood typically has radome - like characteristics; the radar control component module is fixed to the fan controller to ensure seamless integration.

[0055] Integrated radar component: In the third embodiment, the integrated radar component is an integral part of the fan control unit and / or the printed circuit board. This configuration simplifies the design and control system of the fan by embedding the radar function into the existing components.

[0056] In the above - mentioned embodiments, communication between the radar module and the fan controller typically occurs via half - duplex or full - duplex communication. If full - duplex communication is used, the controller can provide real - time status information to the radar module, enabling more dynamic and responsive fan control based on occupancy and user preferences. These installation options ensure flexibility and adaptability when implementing radar technology in ceiling fan systems.

[0057] Figure 1 As shown, according to an embodiment of the present invention, a ceiling fan (101) with an integrated radar module system (100) installed indoors. It should be clear that the subject matter covers devices other than fans, such as light bulbs, air - conditioning systems, mirrors, vehicles, drones, laptops, ovens, grills, etc. The radome - shaped ceiling fan hood is also a protective cover for the ceiling fan, which houses the radar sensor and other internal components of the ceiling fan. The radome surrounds and protects the radar module and other electronic components. A double - bed (102) under the ceiling fan shows a double - bed located under the ceiling fan. This demonstrates the typical position of a ceiling fan in a bedroom. Components such as a radar (103) are integrated into the fan, enabling gesture recognition and control, adding convenience to the user experience.

[0058] Figure 2 As shown, according to an embodiment of the present invention, a radar module block diagram (200) and its interconnection with ceiling fan / light control. The radar and other components inside the radome include a radar - on - chip (ROC) (212), an artificial intelligence (AI) processor (210) and module, a communication and control unit (214), a fan or light control unit (218), a power supply unit (220), and an optional on - board antenna (216). The radome may also include a lighting device.

[0059] Figure 3 As shown, according to an embodiment of the present invention, starting the ceiling fan with an intuitive arm movement. Gesture control of the ceiling fan system (300) allows a user (305) in any position, whether sitting, standing, or lying down, to perform hand or arm movements (306). The control unit in the ceiling fan (301) identifies and classifies the gestures (304). In response to the user's gesture, the control unit in the ceiling fan will perform functions accordingly based on the gesture.

[0060] As shown in FIGS. 4A-4B, according to an embodiment of the present invention, a diagram of an elderly woman sitting on a stool pulling the right hand fan rope and the left hand fan rope. This is a scenario of the prior art, where the user (who can be an elderly person or a child) needs a stool to reach the rope of the ceiling fan to perform an action. However, using this method is not safe and convenient for the user because there is a risk of falling and getting injured during use.

[0061] As Figure 4a - 4b shown, a system (400) having a ceiling fan (401) includes a physical rope (407). This is a situation of the prior art. The user (the elderly woman in the scenario) uses a stool (408) to contact the physical rope of the fan and uses Figure 4a the left hand in Figure 4b and the right hand in

[0062] to perform a downward pulling action (409) to change the state of the ceiling fan.

[0063] As Figure 5a - 5b shown, in a similar scenario, the user (an elderly woman) does not need a stool or steps to reach the physical rope of the ceiling fan 501. The user can perform similar gestures, such as downward pulling gestures (510, 511), while standing, sitting, or lying down to control the function of the ceiling fan. This improvement and enhancement bring comfort and safety to the user. This is also suitable for children who have difficulty reaching the physical rope of an existing ceiling fan.

[0064] Figure 6 shown, according to an embodiment of the present invention, a method of operating a ceiling fan control state machine 1.

[0065] The gesture control of a ceiling fan system (600) has a control unit. The control unit can control one or more different states. Figure 6 One state is shown and described, where (660) is a power switch that can be turned on / off through a physical switch or through a user gesture. To turn on / off the ceiling fan through a user gesture, the power supply or the main switch needs to be turned on.

[0066] The method includes: detecting the presence of indoor users through radar-based technology, represented by (662); the radar in the ceiling fan detecting one or more users, represented by (664); when a user is detected, the control unit of the ceiling fan makes a decision: disabling the power when the user is not in the room, represented by (666), or enabling the power, represented by (668).
