[0024] The present invention relates to a multifunctional cooking assistive device that adapts to the user’s needs, automates cooking tasks, provides real-time guidance, ensures safety, and simplifies cleaning, thus enhancing the overall cooking experience with minimal effort and risk.

[0025] Referring to Figure 1, an isometric view of a multifunctional cooking assistive device is illustrated, comprising a platform 101 positioned over a ground surface by means of plurality of extendable legs 102 arranged beneath the platform 101, an artificial intelligence based imaging unit 103 installed over the platform 101, a pair of induction based coils 104 integrated with the platform 101, a chamber 105 is arranged with the platform 101, an augmented reality holographic projection unit 106 is configured with the platform 101 by means of an extendable shaft 107, a speaker 108 is mapped over the platform 101, a microphone 109 is mapped over the platform 101, a pair of primary motorized sliding units 110 installed with front portion of the platform 101, a transparent panel 111 configured with a heat resistant glove 112 and a horizontal rod 113 configured with the shaft 107 by means of a motorized sleeve 114.

[0026] Referring to Figure 1, further illustrates a motorized clamp 115 configured with the rod 113, a ladle 116 for stirring the food item, a motorized intermittent reciprocating rotation arrangement 117 installed between the clamp and rod 113, a motorized gripper 118 is configured with the rod 113, a pneumatic link 119 installed between the rod 113 and the gripper 118, a cleaning unit 120 configured with the platform 101 by means of a pair of secondary motorized sliding units 121, cleaning unit 120 is configured with a bar 122 attached with the sliders and arranged with plurality of motorized brushes 123, a multi-sectioned cleaning agent reservoir 124 attached with the bar 122 and installed with an electronic nozzle 125 and an exhaust fan 126 installed with the platform 101 by means of a telescopic pole 127.

[0027] The device disclosed herein includes a platform 101 that is positioned over a ground surface and supported by a plurality of extendable legs 102 arranged beneath the platform 101. These legs 102 are developed to provide adjustability in height in view of allowing the platform 101 to be positioned at the optimal height based on the user's physical attributes, such as their height, to enhance ergonomics and ease of use. This adjustability aids in ensuring the comfort and convenience of the user for enabling them to engage with the platform 101 without bending over or straining during food preparation, cooking, and other tasks.

[0028] An artificial intelligence (AI)-based imaging unit 103 mounted above the platform 101 that include camera that work in conjunction with a processor to capture and process images of the user who is present in proximity to the platform 101. The imaging unit 103 consists of computer vision protocols that analyze visual data in real time to recognize and track the user’s position and movements. The processor aids in interpreting the visual information provided by the imaging unit 103, determining specific features such as the user’s height, posture, and their orientation relative to the platform 101.

[0029] Herein, an inbuilt microcontroller is linked with the imaging unit 103 to receive processed data about the user’s position and physical attributes, such as height. The microcontroller determines the height of the user based on the information captured by the imaging unit 103. This is achieved through protocols within the microcontroller that analyze the visual data and calculate the user’s height with high accuracy. The height determination is not merely a static reading but is capable of tracking changes in the user’s position, allowing for continuous adjustments in real-time if necessary. This ensures that the platform’s height is constantly adjusted to provide the best possible ergonomic configuration for the user, whether they are standing, sitting, or moving around the platform 101.

[0030] Based on the user’s height, a motorized drawer arrangement integrated with each of the platform’s legs 102 gets actuated by the microcontroller which receives data from the imaging unit 103 regarding the user's height and enable the legs 102 of the platform 101 to either extend or retract. The actuation of these motorized drawers ensures that the platform 101 is positioned at the optimal height for the user, whether they are standing, sitting, or engaged in other tasks. The motorized mechanism provides a smooth and precise adjustment, which respond to changes in the user’s height or preference in real-time. As the platform 101 is automatically adjusted to the correct height based on the user’s measurements, the device minimizes physical strain, reduces the need for bending over or reaching awkwardly, and creates a more comfortable environment for cooking. The continuous adjustment, which is responsive to the user’s position, provides a customized experience that increases usability and prevents discomfort during food preparation.

[0031] In addition to the motorized adjustment of the platform’s height, the platform 101 also integrates a pair of induction-based coils 104 into the platform 101 that are intended to be accessed by the user to place a cooking utensil, such as a pot or pan, in which a food item is to be cooked. The coils 104 provide a convenient and efficient means for the user to heat or cook food by offering induction cooking, which is faster and more energy-efficient than traditional methods. Induction cooking relies on electromagnetic energy to directly heat the cooking utensil, making this a safe and efficient option for cooking. The placement of these coils 104 on the platform 101 allows for a continuous cooking experience, with the user able to place their cooking utensils directly on the platform’s surface.

[0032] Building on this, the platform 101 is installed with a storage chamber 105 to allow users to store various cooking utensils such as spoons, and tools needed during food preparation. The chamber 105 offers an organized and accessible way to store cooking tools such as ladles, spatulas, tongs, or measuring spoons. This reduces clutter on the cooking area and ensures that all necessary utensils are conveniently within reach. The chamber 105 is developed to be spacious enough to accommodate multiple utensils and tools, ensuring that the user has everything they need for cooking in one centralized location.

[0033] A computing unit is equipped with a user interface that allows the user to provide input regarding the dish they wish to cook. The interface is developed to be intuitive and easy to use, ensuring that users quickly and accurately specify their cooking preferences. The user is able to select or input the dish they intend to prepare, either by choosing from a pre-existing list of recipes or by manually entering the details of the dish. This interface also allows the user to customize certain aspects of the recipe, such as the level of spiciness, preferred cooking methods such as sauteing, simmering, or dietary restrictions. Once the user has provided this input, the microcontroller which is wirelessly connected to the computing unit receives the data and processes the data to determine the precise cooking parameters for the selected dish.

[0034] Based on the user-specified dish, the microcontroller evaluates several key factors that are essential for successful cooking, such as the heat intensity, the amount and type of ingredients, and the cooking techniques to be applied. The device uses data from a vast recipe database and adjusts these factors according to the particular needs of the dish. For example, if the user selects a delicate fish dish, the device automatically recommends a low heat setting to avoid overcooking. On the other hand, for a stir-fry, the device adjusts the heat intensity to a higher setting. Also, the device provides guidance on the precise amounts of each ingredient required for the dish, based on the user's input and also offer suggestions for ingredient substitutions if certain items are unavailable, helping users manage their pantry efficiently.

[0035] An augmented reality (AR) holographic projection unit 106 integrated with the cooking platform 101 offers users a hands-free, visually immersive cooking experience. This AR unit 106 is configured to project holographic visuals that display the step-by-step cooking instructions for the dish that the user has selected. The projection unit 106 is mounted on an extendable shaft 107 that allows it to move and adjust the projected visuals, positioning them at the optimal angle and height for the user to easily follow. This movement is controlled by the microcontroller, which synchronizes the AR unit’s positioning and the user’s actions. Once the user inputs their selected dish into the interface, the holographic projection unit 106 displays clear, three-dimensional visuals of the cooking steps, ingredient preparation, cooking techniques, and even timing for specific stages of the dish.

[0036] For example, if the user is preparing a complex dish, such as a layered cake, the projection unit 106 show the user the exact process, step by step, in real-time. These instructions are customized to match the specific recipe parameters like whether to bake or sauté, the exact mixing method, or how to assemble the dish. The holographic visuals are also interactive, where the device responds to the user’s progress by adjusting the visual cues depending on the actions being taken. If the user performs a step incorrectly, the AR unit 106 detect this and project an alternate or corrective visual instruction to guide the user back on track. These holograms reduce the need for users to constantly refer to recipe books which enables them to focus on cooking in an intuitive, hands-on manner.

[0037] Simultaneously, a speaker 108 is mapped onto the platform 101 to further enhance the guidance experience. The speaker 108 works in conjunction with the AR unit 106 to produce voice commands that assist the user in a more auditory manner. The speaker 108 delivers important instructions regarding the evaluated amount and type of ingredients, cooking techniques, and alerts the user when it’s time to move to the next step in the cooking process. For example, if the holographic visuals instruct the user to "add 200 grams of flour," the speaker 108 audibly say, "Please add 200 grams of flour to the bowl." If the device detects that the user has not followed the instruction correctly, the speaker 108 prompt the user again with a gentle reminder or more specific guidance.

[0038] Moreover, the voice guidance goes beyond simple ingredient instructions and provide valuable information, such as cooking tips or alerts about potential risks. If the device detects that the food is nearing the end of the cooking time, for example, the speaker 108 issues a reminder to "Check the dish, it's nearly ready," or notify the user when to adjust the heat intensity for delicate cooking stages. The combination of holographic visuals and voice commands creates a multi-sensory experience that allows the user to stay focused on the cooking process while receiving real-time, easy-to-follow assistance, making the cooking experience both engaging and effective.

[0039] An infrared heat signature unit integrated with the cooking platform 101 ensures precise temperature control during the cooking process, thus preventing burning, overcooking, or undercooking of the food. This unit is essentially a specialized infrared sensor or array of sensors developed to continuously monitor the temperature of the food item being cooked within the utensil, such as a pot, pan, or cooking vessel. Mounted above or near the cooking surface, the infrared heat signature unit operates by emitting infrared radiation and detecting the thermal radiation emitted from the food and cooking utensil. Infrared sensors are highly sensitive to heat and capture very subtle changes in temperature, providing real-time, accurate data regarding the current state of the food. The infrared sensor works by measuring the heat emitted by the food item. This heat is typically emitted as infrared radiation, which the sensor picks up and converts into a digital signal. The microcontroller continuously receives this data and analyzes it to determine the exact temperature of the food. By constantly comparing the actual temperature with the target temperature required for the dish (a value that is previously set by the user’s input or derived from the dish recipe in the device) the microcontroller decide whether the food is being cooked at the correct intensity.

[0040] When the infrared heat signature unit detects that the food has reached a temperature higher or lower than what is required for the recipe, it sends feedback to the microcontroller to adjust the heating elements integrated into the platform 101. Specifically, the microcontroller controls the induction coils 104 on the platform 101 to either increase or decrease the heat intensity based on the discrepancy between the current temperature and the desired temperature for that stage of cooking. For example, if the sensor detects that the food is cooking too quickly and reaching a temperature that cause burning or overcooking, the microcontroller reduces the heat output by the induction coils 104 to prevent further increase in temperature. On the other hand, if the sensor detects that the food is not cooking fast enough and the temperature is lower than expected, the microcontroller increases the heat intensity, ensuring that the food is cooked evenly and in a timely manner.

[0041] A microphone 109 is mapped over the platform 101 that enables voice-controlled interaction, making the cooking process more hands-free and efficient. The microphone 109 is placed to capture voice commands from the user while they are working around the cooking platform 101. This microphone 109 works by continuously monitoring the surrounding environment for audio input, specifically listening for keywords or commands related to the user’s needs. For example, if the user needs assistance with handling a hot cooking utensil, they issue a simple voice command, such as “Help me handle the utensil” without needing to physically interact.

[0042] Once the microphone 109 picks up the voice command, it transmits the audio signal to the microcontroller for processing the received voice input using voice recognition protocol that identify specific commands or requests made by the user. The voice recognition protocol is trained to interpret common commands that are relevant to the cooking process, such as requests for handling hot cookware, cleaning, stirring, or adjusting the cooking temperature. After recognizing the voice command, the microcontroller actuates a pair of primary motorized sliding units 110 that are installed along the front portion of the platform 101. These sliding units 110 are developed to move or translate a transparent panel 111 that is configured with a heat-resistant glove 112. The sliding units are equipped with motors that allow precise movement and positioning. When the voice command is detected, the microcontroller directs these motorized units to shift the transparent panel 111 into position in front of the cooking utensil that the user needs to handle.

[0043] The panel 111 is developed to deploy the heat-resistant glove 112 smoothly, bringing it within easy reach of the user. The heat-resistant glove 112 allows the user to safely and comfortably handle hot cooking utensils without risking burns or injuries. The glove 112 is typically made from specialized materials such as silicone or other heat-resistant fabrics that provide protection from high temperatures. By deploying the glove 112, the platform 101 ensures that the user does not have to physically reach into a drawer or cupboard to retrieve it, thus enhancing the cooking process and reducing the chances of accidents in the kitchen. Once the glove 112 is deployed in front of the utensil, the user easily slips their hand into the glove 112 and safely manipulate the hot cookware. The glove 112, combined with the motorized sliding units 110, allows the user to continue cooking without being interrupted by the need to manually fetch protective gear or risk exposure to excessive heat.

[0044] A horizontal rod 113 is configured with the shaft 107 and connected to a motorized sleeve 114, which allows the rod 113 to move or adjust its position based on the user’s specific requirements. The rod 113 is controlled by the microcontroller, which processes commands received from the user via the microphone 109. When the user issues voice command such as “Stir the food,” “Stir at medium speed,” or “Stir the soup”, the microcontroller immediately interprets the input and determines the required action. For example, the microcontroller identifies commands related to both the action of stirring and the desired stirring speed. The ability to specify speed, such as slow, medium, or fast, provides a customized cooking experience, allowing the user to achieve the perfect texture and consistency for the dish they are preparing.

[0045] Once the voice command is received and processed, the microcontroller activates the motorized sleeve 114 that controls the horizontal rod 113. The sleeve 114 is developed to extend or retract, enabling the rod 113 to position itself directly above the cooking utensil where stirring is required. The horizontal rod 113 is carefully positioned to ensure that this move across the cooking surface and efficiently stir the contents of the utensil. The motorized sleeve 114 functions with precision, allowing the rod 113 to rotate and be placed over the food container without any manual effort required from the user.

[0046] A motorized clamp 115, which is configured at the end of the horizontal rod 113 aids in securing a ladle 116 that is used to mix the food. The clamp 115 is also controlled by the microcontroller, ensuring that this engages the ladle 116 firmly and accurately. Upon receiving the command to stir, the microcontroller signals the clamp 115 to grip the ladle 116, which is then positioned in the cooking utensil. The clamp’s grip mechanism is developed to hold the ladle 116 securely while the rod 113 is in motion, preventing it from slipping or detaching during the stirring process. Once the ladle 116 is engaged and the rod 113 is properly positioned, the rod 113 to rotate in a manner that is consistent with the speed and direction specified by the user. The rod 113 moves in a continuous or intermittent manner, mimicking the stirring action that is typically be done manually by the user. The speed of rotation is adjusted based on the user’s input, whether the user prefers a slow, gentle stir for delicate dishes or a fast, vigorous stir for more robust preparations. The horizontal rod’s ability to move across the utensil and the engagement of the ladle 116 ensures that ingredients are stirred uniformly, preventing burning or uneven cooking. This minimizes the need for the user to manually intervene, reducing the chances of spilling or splattering, which is common during manual stirring.

[0047] A motorized intermittent reciprocating rotation arrangement 117 installed between the clamp 115 and rod 113 is developed to automate and enhance the stirring for ensuring that the stirring action is performed at a user-specified speed and with the necessary precision. This arrangement 117 enables the gripped ladle 116 which is held by the motorized clamp 115 attached to the horizontal rod 113 to undergo an efficient reciprocating rotation that mimics the manual stirring motion typically performed by the user.

[0048] The motorized member is physically attached to the slider that is configured within a C-shaped channel. The C-shaped channel ensures that the member has the necessary freedom of movement to travel in a linear manner along the channel while also allowing it to rotate in a controlled manner. The motorized member is connected to the clamp 115 that secures the ladle 116 which is used for stirring the food. When the device is actuated by the microcontroller, the motor causes the motorized member to translate through the C-shaped channel, producing a reciprocating motion that generates a consistent rotation of the ladle 116. This back-and-forth movement is crucial because this ensures that the food inside the cooking vessel is stirred in an even and thorough manner. By oscillating the ladle 116 in both directions, the device avoids over-stirring in one direction or missing areas within the pot that need stirring. The intermittent nature of the rotation also provides flexibility for the user to specify how fast or slow they want the food to be stirred.

[0049] A motorized gripper 118, which is configured to be attached to the horizontal rod 113 of the platform 101. The gripper 118 aids in ensuring the utensil remains in a secure and stable position during cooking, particularly when stirring is being performed. When the device detects that stirring is required, the motorized gripper 118 actuates to grip the utensil firmly, preventing it from shifting or tipping over during the stirring motion. This is crucial because, during the stirring process, the user not only move the ladle 116 but also maintain a stable and consistent position of the cooking utensil to avoid spills or accidents. In conjunction with the motorized gripper 118, a laser sensor is installed on the platform 101 and synchronized with the imaging unit 103 to detect the dimensions and position of the utensil placed on the platform 101, ensuring that the device has real-time feedback on the utensil’s location and size.

[0050] The imaging unit 103 captures this data, which is then processed by the microcontroller. Based on this information, the microcontroller determines the appropriate adjustments to be made by the motorized gripper 118. If the utensil needs to be repositioned or adjusted for the correct placement of the stirring ladle 116, the microcontroller actuates a pneumatic link 119 that is connected between the rod 113 and the gripper/clamp. This link 119 allows the gripper 118 to extend and retract, adapting to the utensil's size and ensuring a secure grip on the utensil before initiating the stirring action.

[0051] The extension mechanism, powered by the pneumatic link 119, ensures that the gripper/clamp extend precisely to the required position for gripping the utensil securely. Once the gripper 118 established a firm hold on the utensil, this is engaged to move or position the ladle 116 in a way that facilitates stirring. The device adjusts to different sizes of utensils by dynamically modifying the gripper's positioning. The ability of the gripper 118 to adjust its position based on sensor data ensures that a wide variety of cooking vessels are used without manual intervention.

[0052] The microphone 109 allows the user to provide voice commands for various tasks, such as repositioning the cooking utensil on the platform 101 or moving it between induction coils 104. If the user issues a command to reposition the utensil to another coil, the microcontroller responds by activating a motorized slider installed with the rod 113. This slider is responsible for moving the gripper/clamp with the utensil securely held to a new location over the desired coil. The motorized slider translates the gripper/clamp along a horizontal path, allowing the user to place the utensil over the appropriate induction coil, ensuring it is heated according to the user’s preferences.

[0053] The microphone 109 is pre-fed to detect the whistle produced by a pressure cooker. The pressure cooker operates by building up steam inside the pot, and when the pressure reaches a certain level, the valve opens and releases steam, creating a distinctive whistling sound. This sound serves as a reliable indicator of cooking stages, and its frequency and timing provide valuable information about the progress of the food being cooked. The microphone 109 is connected to the microcontroller, which processes the sound signals in real time. The microcontroller uses a pattern recognition protocol that distinguishes the pressure cooker’s whistle from other background noises. Once the whistle is detected, the device counts the number of whistles emitted by the pressure cooker. This counting process is crucial because different dishes require a specific number of whistles to reach their desired cooking time or pressure level. For example, certain recipes require three whistles, while others need five or more. By counting the number of whistles, the microcontroller determines if the cooking process is progressing as expected.

[0054] Once the number of whistles is detected and counted, the device sends a relative notification to the computing unit. The computing unit, which houses the user interface, processes this information and displays an update to the user, notifying them of the cooking status. For example, the display show "3 whistles detected," or give a warning if the number of whistles is lower than expected, suggesting that the cooking process need further attention. This feedback enables the user to monitor the progress of the food and decide when to intervene, whether to reduce heat, stop cooking, or take further actions. the information is relayed to the voice speaker 108 for real-time verbal updates, ensuring the user is always informed of the cooking stage without needing to physically check the pressure cooker.

[0055] To complement the whistle detection process, a timer is integrated within the device via the microcontroller. This timer works in parallel with the whistle detection to track the duration between whistles. The timer is essential because it ensures that the whistle pattern occurs within the expected time intervals, which is indicative of normal operation. If the time between whistles becomes too long or the whistle is delayed beyond a predefined threshold, this signal a problem, such as the pressure cooker not achieving the proper pressure or the heat source being inadequate.

[0056] If the whistle does not occur within a pre-set time duration, the device interprets this as an anomaly and initiate a safety protocol to prevent potential accidents. The microcontroller, upon detecting the failure to meet the expected whistle pattern, direct the gripper 118 to engage the pressure valve of the pressure cooker. This action involves the gripper 118 grasping the valve and releasing excess pressure in a controlled manner to prevent dangerous buildup inside the cooker.

[0057] In addition to releasing the pressure, the device also turns off the induction coils 104 supplying heat to the pressure cooker. This is a safety measure developed to prevent further cooking once an irregularity is detected. By turning off the heat, the device ensures that the food does not continue to cook under unsafe conditions, reducing the risk of overcooking or burning. The microcontroller is pre-fed to perform this action automatically if the timer fails to detect the appropriate whistle interval after a predefined period, ensuring that the cooking process is halted safely.

[0058] A cleaning unit 120 is connected to the platform 101 through a pair of secondary motorized sliding units 121 activated by the microcontroller and allow the cleaning unit 120 to move over the platform 101. The sliding mechanism ensures that the cleaning unit 120 cover the entire surface of the platform 101, reaching all areas that need cleaning. When the user issues a voice command through the microphone 109, the microcontroller interprets the command and actuates the motorized sliding units 121 to move the cleaning unit 120 into the required position on the platform 101. This precise translation ensures that the cleaning unit 120 is correctly positioned and effectively clean the platform 101, providing uniform coverage without the user needing to manually reposition any part.

[0059] Once the cleaning unit 120 is translated into position over the platform 101, the cleaning process begins. The cleaning unit 120 is equipped with a bar 122 that is mounted on the motorized sliding units 121. The bar 122 serves as the core structural element, supporting several motorized brushes 123 to scrub the surface of the platform 101, removing any grease, food residues, or stains left after cooking. The brushes 123 allows them to move with precision and apply the appropriate amount of pressure to ensure effective cleaning. These brushes 123 are typically configured in a way that they rotate in multiple directions or even oscillate to agitate the surface, ensuring a deep clean that is difficult to achieve manually.

[0060] In addition to the brushes 123, the cleaning unit 120 is further enhanced by the presence of a multi-sectioned cleaning agent reservoir 124. This reservoir 124 is attached to the cleaning bar 122 and is developed to hold various types of cleaning agents that are needed for different cleaning tasks. The cleaning agent is a general-purpose cleaner, a degreaser, or a specialized solution depending on the type of residues left on the platform 101. The bar 122 incorporates an electronic nozzle 125, which is connected to the reservoir 124 and is controlled by the microcontroller. When the cleaning function is activated, the microcontroller signals the nozzle 125 to dispense a regulated amount of the specific cleaning agent over the platform 101. The microcontroller ensures that the appropriate amount of cleaning agent is dispensed, preventing waste and ensuring the cleaning agent is applied evenly across the surface. The dispensing process is synchronized with the motion of the motorized brushes 123, allowing the cleaning agent to be applied in tandem with the scrubbing action. This coordination optimizes the cleaning process, as the agent helps to break down grease, food particles, and other stubborn residues, which the brushes 123 then effectively scrub away.

[0061] After the cleaning agent is dispensed and the platform 101 is scrubbed by the motorized brushes 123, the final step of the cleaning process involves drying the platform 101. To achieve this, the cleaning unit 120 is equipped with an air-blowing unit, which is positioned on the bar 122. The air-blowing unit is activated by the microcontroller following the completion of the scrubbing action to blow air over the cleaned surface to remove excess moisture, helping the platform 101 dry quickly and thoroughly. The air-blowing unit operates using a fan or air compressor that blows a steady stream of air over the surface of the platform 101, ensuring it is completely dry and ready for use once again.

[0062] This drying process not only ensures that the platform 101 is free from water spots but also prevents any moisture from remaining on the surface, which otherwise contribute to the growth of bacteria or mildew. By rapidly drying the platform 101, the device ensures that the cooking area is immediately available for the next use, reducing downtime and maintaining a high level of convenience for the user.

[0063] An exhaust fan 126 is positioned above the cooking area on the platform 101, the exhaust fan 126 is mounted on a telescopic pole 127, which is developed to extend and retract based on the cooking needs of the user. This telescopic pole 127 is controlled by the microcontroller which ensures that the exhaust fan 126 is positioned optimally above the cooking area at all times. As cooking generates varying amounts of heat, steam, and smoke especially when high-temperature cooking methods such as frying, grilling, or sautéing are involved, the exhaust fan 126 automatically adjusts its height via the telescopic pole 127 to accommodate the specific cooking process being performed. This ensures that the fan 126 remains in the most effective position to capture and expel airborne pollutants such as smoke, grease particles, and excess moisture, which otherwise linger in the kitchen environment and potentially affect the quality of the food or create an unpleasant cooking experience. The telescopic pole's ability to extend or retract based on the user’s needs means the exhaust fan 126 adapt to different cooking scenarios, whether it's a low-temperature simmer or a high-temperature searing process.

[0064] Furthermore, the activation and control of the exhaust fan 126 are linked with the microcontroller that monitor temperature and air quality. The fan 126 is automatically activated based on the detected rise in temperature or the presence of excessive smoke. Additionally, users manually control the exhaust fan 126 through the voice commands, offering flexibility and ensuring that the device provides optimal performance in varying cooking conditions. The fan 126 itself is developed to operate quietly and efficiently, so it doesn’t disrupt the cooking process or interfere with the user’s experience. By actively removing smoke and vapors, the exhaust fan 126 also contributes to the longevity of the cooking environment, preventing the buildup of grease on surfaces and reducing the risk of respiratory discomfort due to prolonged exposure to cooking fumes. This enables a cleaner, more breathable atmosphere, allowing users to cook in a pleasant, well-ventilated space.

[0065] The imaging unit 103 integrated with the platform 101 to detect and analyze the presence of a child in proximity to the cooking area. The imaging unit 103, equipped with computer vision protocols constantly monitors the space around the platform 101 and tracks movements within its vicinity. When the child enters the cooking area, the imaging unit 103, using real-time image processing, identifies the child’s presence and communicates this data to the microcontroller. The microcontroller interprets the input from the imaging unit 103 and determines that the child is in a potentially hazardous area, especially given the presence of hot cooking surfaces, boiling liquids, or other kitchen dangers. To ensure the child’s safety, the microcontroller activates both the augmented reality projection unit and the speaker 108, providing an immediate cautionary notification. This warning, which is visually displayed on the platform’s projection unit, offers a clear, understandable message, possibly accompanied by visuals such as a red alert or an animated reminder, urging the child to stay away from the cooking area.

[0066] Simultaneously, the microcontroller triggers the speaker 108 to emit an audible voice command that further reinforces the cautionary message, ensuring that the child is made aware of the danger. These notifications are developed to be clear and direct, using a tone and language that is easy for a child to comprehend. In addition to these immediate warnings, the microcontroller sends a real-time alert notification to the computing unit of the user, notifying them that a child is present near the platform 101 during cooking. This alert is in the form of a visual pop-up, a vibration, or a sound on the user interface, depending on the user’s preferences.
