Description:FIELD OF THE INVENTION

[0001] The present invention relates to a learning and development device for early childhood that revolutionize interactive education through a multifaceted, adaptive, and engaging approach. The device aims to provide a comprehensive and highly responsive educational environment that caters to the individual needs of young children, fostering their cognitive, motor, and sensory development in a playful and intuitive manner.

BACKGROUND OF THE INVENTION

[0002] Learning and development assistance is crucial for early childhood because these years (birth to age of eight) are a period of rapid brain development. Quality experiences during this time lay the fundamental groundwork for a child's cognitive, social, emotional, and motor skills, profoundly impacting their future academic success, well-being, and overall lifelong potential. Problems in early childhood learning often stem from diverse individual needs, limited access to quality programs, and insufficient resources (including trained educators and engaging materials). Children also face developmental delays or behavioral challenges that require tailored support. Additionally, inconsistent parental involvement and socioeconomic disparities further hinder a child's optimal development and learning progress.

[0003] Traditionally, early childhood learning has relied on tangible aids like wooden blocks, puzzles, picture books, and simple art supplies, alongside teacher-led instruction. While valuable for hands-on exploration and social interaction, these devices inherently lack automation capabilities. They do not adapt content dynamically to a child's learning pace, provide instant, personalized feedback, or monitor progress autonomously. There's no built-in means for self-correction based on a child's performance, nor they offer multi-sensory integration (like aligning scents with visuals) or real-time reporting to parents, making comprehensive, automated personalized learning difficult.

[0004] US6579100B1 discloses about a learning system method for infants, toddlers and young children which uses selected visuals stored on an audiovisual storage and playback device in conjunction with unique flash cards to provide an enhanced learning experience.

[0005] US7063535B2 discloses about the invention provides caregivers with pragmatic systems and methods for implementing current knowledge of early childhood brain development and for facilitating meaningful interaction with a child in their care. The invention further provides systems and methods that enable caregivers to provide a child with a stimulating environment that includes purposeful activities in a playful, interactive context.

[0006] Conventionally, many devices are available in market for early childhood learning and development. However, these devices lack in comprehensive real-time adaptability, personalized multi-sensory engagement, and automated instructional guidance, often failing to provide seamless data-driven insights into a child's progress for parents or educators.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of providing personalized, adaptive, and multi-sensory learning experiences, while offering automated guidance and real-time insights into a child's developmental progress for both caregivers and educators.

[0021] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0022] The present invention relates to a learning and development device for early childhood that is capable of dynamically adapting its teaching approach to each child's unique needs and progress. The device provides a multi-sensory learning environment by engaging sight, sound, and touch, fostering cognitive and motor skill development through interactive guidance and personalized content delivery.

[0023] Referring to Figure 1, an isometric view of a learning and development device for early childhood is illustrated, comprising a body 101 configured with multiple motorized wheels 102, a telescopically operated leg 103 attached in between each of the wheels 102 and body 101, an artificial intelligence-based imaging unit 104 installed on the body 101, an extendable cavity 105 within the body 101 housing foldable plates 106, an L-shaped chair structure 107 supported by telescopic rods 108, a writing pad 109 installed on the body 101, a motorized two-axis slider 110 is provided on the body 101 and integrated with an articulated robotic arm 111 being connected to the slider 110 via a telescopic bar 112 and a ball-and-socket joint 113, a holographic projection unit 114 configured with the body 101, a fragrance spraying unit 115 with a chamber 116 provided on the body 101, a dedicated compartment 117 within the body 101 housing a vertical plate 118, multiple horizontal sliders 119 are positioned above the plate 118, a C-shaped clamp 120 with a pincer arrangement 121 is positioned behind each letter unit 122, a storage unit 123 provided within the body 101, multiple pneumatic frames 124 are arranged within the storage unit 123, and an audio output unit 125 is mounted on the body 101.

[0024] The device disclosed herein includes a body 101 is developed to be positioned in an educational setting for aiding early childhood education. The body 101 herein includes all necessary operational components to assist young children in their learning.

[0025] The body 101 is installed with push button, accessed by a user to activate the device for performing the required operations. When the user presses the push button, the electrical circuit is completed, which in response turns the device on. The push button is integrated with an actuator and a spring, which are automatically activated when pressed. They work together to move the internal contact, completing the circuit and allowing electrical current to flow, thereby activating an inbuilt microcontroller.

[0026] The microcontroller associated with the device is pre-fed to detect the signal and actuate/ activate the required component of the device. The microcontroller used herein is pre-fed using artificial intelligence and machine learning protocols to coordinate the working of the device. Further, the microcontroller activates a laser-based sensor embedded over the body 101 to determine level of the surface.

[0027] The laser sensor comprises an emitter and a receiver, operating on the principle of measuring the time delay for a laser beam to travel to a surface and back. The laser sensor emits light towards the surface. When the laser beam strikes this surface, it reflects back towards the sensor's receiver. Upon detecting the reflected beam, the sensor precisely measures the time taken for the laser beam's round trip. The sensor then calculates this travel time. Based on this calculation, the distance (or level) is converted into an electrical signal in the form of current, which is then sent to the microcontroller. Upon receiving these signals, the microcontroller actuates a telescopically operated leg 103 of installed in between multiple motorized wheels 102 and body 101 to stabilize the body 101 over the surface.

[0028] The telescopically operated legs 103 are linked to a pneumatic unit, including an air compressor, air cylinders, air valves and piston which works in collaboration to aid in extension and retraction of the legs 103. The pneumatic unit is operated by the microcontroller, such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the legs 103 and due to applied pressure the legs 103 extends and similarly, the microcontroller retracts the telescopically operated legs 103 by closing the valve resulting in retraction of the piston. Thus, the microcontroller regulates the extension/retraction of the legs 103 in order to stabilize the body 101 over the surface in the educational setting.

[0029] The motorized wheels 102 comprise a pair of wheel coupled with a motor via a shaft wherein upon receiving the command from the microcontroller by the motor, the motor starts to rotate in clockwise or anti-clockwise direction in order to provide movement to the wheels 102 via the shaft. The wheels 102 thus allow maneuvering of the body 101 in the educational setting.

[0030] Once the body 101 is stabilizing over the surface, the microcontroller actuates foldable plates 106 housing in an extendable cavity 105 within the body 101 to automatically unfold into an L-shaped chair structure 107 supported by telescopic rods 108 in a crisscross arrangement. Initially, the foldable plates 106 are compactly stowed within this cavity 105. Upon command from the microcontroller, the extendable cavity 105 begins to open or articulate, creating the necessary space for the unfolding plates. The extendable cavity 105 comprises a motorized sliding arrangement to open the cavity 105. This arrangement, is driven by a compact electric motor, directly actuates the movement of the cavity's movable sections. As the motor engages, it either pulls or pushes a lead screw, a rack-and-pinion unit, or a set of linear rails, causing the cavity's panels or segments to smoothly slide outwards from within the device body 101. This precise, controlled motion expands the cavity 105, enabling the plates 106 to unfold.

[0031] Simultaneously, or immediately after, a motorized deployment unit (likely is involving but not limited to small electric motors and gears) within the cavity 105 actuates the initial movement of the foldable plates 106. These motors are connected to hinges or pivot points on the plates 106, initiating their outward and downward swing. As the plates 106 unfold, the telescopic rods 108 are strategically arranged in a crisscross arrangement and are also typically motorized or spring-loaded with controlled release. As the plates 106 extend, the telescopic rods 108 simultaneously extend, providing the necessary structural support. The extension/retraction of the telescopic rods 108 is regulated by the microcontroller by in the same manner as the telescopically operated legs 103, by employing the pneumatic unit.

[0032] The crisscross configuration ensures stability and weight distribution for the L-shaped chair. The motors within the cavity 105 precisely control the unfolding sequence, ensuring that the plates 106 and rods 108 extend in a coordinated manner to form the desired L-shape. Sensors like limit switches or position encoders are likely integrated into this arrangement to provide feedback to the microcontroller, allowing it to monitor the unfolding process and stop the motors once the chair is fully deployed and locked into position. When the device is deactivated, the process reverses: the motors retract the telescopic rods 108, and the plates 106 fold back into their compact, stowed position within the extendable cavity 105.

[0033] Once the child is seating on the chair-like structure 107, the microcontroller activates an artificial intelligence-based imaging unit 104 mounted on the body 101 to capture images in proximity of the body 101 for identifying the children. The imaging unit 104 comprises of an image capturing module including a set of lenses that captures multiple images in surrounding of the body 101, and the captured images are stored within memory of the imaging unit 104 in form of an optical data. The imaging unit 104 also comprises of a processor that is encrypted with artificial intelligence protocols and integrated with a facial recognition protocol. This allows it to use facial recognition to identify individual children and load their associated learning profiles accordingly. The processor then processes the optical data to extract relevant information from the captured images. The extracted data is converted into digital pulses and bits, which are transmitted to the microcontroller. The microcontroller processes this received data and identifies individual children present.

[0034] Upon successful facial recognition, the microcontroller communicates with a centralized database linked with the microcontroller, to retrieve and load the identified child's specific learning profile. This profile contains crucial information like age group, subject needs, enrolled curriculum, and historical interaction data, thus ensures personalized learning. The imaging unit 104 continuously captures video footage of the child's activities in proximity to the device. This optical data is stored in the imaging unit’s memory. The imaging unit's processor, through artificial intelligence protocols, processes the captured optical data and extracts relevant information about the child's actions, interactions, and engagement. The extracted data is converted into digital pulses and bits and transmitted to the microcontroller. The microcontroller processes this received data to determine the child's current activity, engagement level, and progress. Based on these insights, it dynamically adapts the difficulty level and content pacing of learning modules. This forms the core of the adaptive learning experience. Additionally, the microcontroller continuously updates the database based on child interaction patterns to further refine and adapt difficulty levels and content pacing.

[0035] Concurrently, the imaging unit 104 is configured to capture, analyze, and transmit secure video feeds to authorized guardians' computing units for ensuring ongoing safety monitoring and engagement. For transmitting the video to the authorized guardians, the microcontroller activates a communication module, which is linked with the microcontroller for establishing the wireless connection between the microcontroller and the computing unit (includes, but not limited to smartphone, tablet or laptop) and inbuilt with a user-interface that is accessed by the guardian to monitor the children’s activities.

[0036] The communication module used herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used herein is preferably a Wi-Fi module that is a hardware component that enables the microcontroller to connect wirelessly with the computing unit. The Wi-Fi module works by utilizing radio waves to transmit and receive data over short distances. The core functionality relies on the IEEE 802.11 standards, which define the protocols for wireless local area networking (WLAN). Once connected, the module allows the microcontroller to send and receive data through data packets.

[0037] A GPS module, is integrated directly with the microcontroller and activated upon command, functions to enhance the device's educational adaptability by detecting its geographical location. When activated, the GPS module communicates with orbiting satellites to triangulate its precise coordinates (latitude and longitude). This raw location data is then transmitted to the microcontroller. The microcontroller processes these coordinates and cross-references them with an internal or cloud-based database that contains geographical information about educational institutions and their affiliated boards. By comparing the device's location with this database, the microcontroller identifies nearby schools, kindergartens, or educational districts, and crucially, determine the specific curriculum or educational board (e.g., CBSE, ICSE, Montessori, local state board) they follow. Based on this identified curriculum, the microcontroller then dynamically adjusts and loads the relevant learning modules and content for ensuring that the educational experience provided by the device is precisely aligned with the pedagogical standards and subject matter relevant to the child's local educational environment.

[0038] Once the educational board is determined, the microcontroller actuates a motorized two-axis slider 110 to give position of an articulated robotic arm 111 configured with the slider 110, over a writing pad 109 installed on the body 101 to demonstrate correct pencil handling. The motorized two-axis slider 110 precisely positions an articulated robotic arm 111 configured with the slider 110 via telescopic bar 112, over the writing pad 109 by utilizing a two independent linear motion axes, often referred to as an X-axis and a Y-axis. Each axis is driven by its own electric motor coupled to a lead screw, timing belt, or rack-and-pinion. When the microcontroller sends commands, the motors for the X and Y axes operate simultaneously or sequentially. The X-axis motor moves the entire assembly including the Y-axis and the robotic arm 111 horizontally across the writing pad 109, while the Y-axis motor moves the robotic arm 111 carriage vertically along the writing pad 109. This combined motion allows the robotic arm 111 to reach any point on the writing pad's surface. Position encoders or limit switches on each axis provide feedback to the microcontroller, ensuring accurate and repeatable positioning, allowing the system to precisely guide the robotic arm 111 to demonstrate writing techniques or assist the child's hand.

[0039] The articulated robotic arm 111 writes on the writing pad 109 by executing a series of precisely controlled movements, controlled by the microcontroller. After being positioned over the writing pad 109 by the two-axis slider 110, the robotic arm 111, holding a writing tool (like a pen or stylus), utilizes its multiple joints (often driven by servo motors) to achieve the necessary degrees of freedom. The microcontroller first processes the desired writing input, whether it's a character to be demonstrated or a word to be guided. This input is translated into a sequence of Cartesian coordinates (X, Y, Z positions) that define the path of the writing tool's tip across the writing pad 109. Using inverse kinematics, the microcontroller then calculates the precise angles and positions that each of the robotic arm's joints adopt to reach these successive X, Y, and Z coordinates. The Z-axis control is critical for lifting and lowering the writing tool to prevent unwanted marks between strokes or characters. As the motors actuate each joint, the telescopic bar 112 allows the arm 111 to extend or retract, and a ball-and- socket joint 113 installed in between the arm 111 and bar 112, provides rotational flexibility, enabling the arm 111 to mimic the natural curvilinear motions of handwriting. The extension/ retraction of the bar 112 is regulated by the microcontroller by in the same manner as the telescopic bar 112, by employing the pneumatic unit for positioning the articulated robotic arm 111 over the writing pad 109. Furthermore, the robotic arm 111 is also configured to gently grip the child’s wrist when they attempt to hold the pencil for assisting in guiding the child’s hand and ensuring proper movement and posture throughout the writing process.

[0040] The ball-and-socket joint 113 provides crucial rotational capability to the robotic arm 111, enabling it to turn at any required angle for complex writing movements. This joint functions as a coupling where a ball joint is securely yet flexibly locked within a socket joint. The design allows the ball joint to move in a full 360-degree rotation within its socket, thus imparting multidirectional rotational motion to the robotic arm 111. This movement is powered by a DC (direct current) motor, which is precisely actuated by the microcontroller to achieve the desired orientation and articulation for accurate handwriting tasks.

[0041] The robotic arm 111 includes pressure sensors to ensure safe wrist guidance without discomfort during handwriting practice. The pressure sensor comprises a sensing element known as a diaphragm that experiences a force exerted by the child's wrist on the arm's gripping surface while guiding the hand. This force leads to a deflection in the diaphragm that is measured by the sensor and converted into an electrical signal, which is then sent to the microcontroller for real-time adjustment of gripping force or to provide feedback/alerts if excessive pressure is detected.

[0042] A holographic projection unit 114, integrated with the body 101, is activated by the microcontroller to display realistic 3D (three-dimensional) visualizations of educational content, such as fruits, animals, and alphabets. This significantly enhances sensory and cognitive development. The holographic projection unit 114 operates by creating and projecting holograms, which are 3D images formed by the interference of light waves. First, a laser light from the unit is split into two beams: an object beam and a reference beam. The object beam interacts with the physical object (or a digital representation thereof), causing its light waves to be altered based on the object's shape and features. The reference beam, meanwhile, remains unchanged. These altered object and reference beams then intersect, creating a complex interference pattern. This pattern is recorded on a photosensitive surface, typically a holographic plate. The recorded interference pattern contains vital information about the phase and amplitude of the light waves, thereby preserving the three-dimensional details of the original object. During projection, a laser beam is directed onto this recorded interference pattern. As the laser light diffracts, it reconstructs the original wave fronts from both the object and the reference beams. These reconstructed wave fronts then create a lifelike three-dimensional image that appears to float in space, providing an immersive learning experience.

[0043] A fragrance spraying unit 115 is integrated into the body 101 that is activated by the microcontroller to enhance learning through the sense of smell and features a chamber 116 containing multiple aroma sections, each holding a distinct fruit- or object-specific scent. When the microcontroller detects that visual teaching content (such as a 3D hologram of an apple) is being displayed, it sends a precise activation signal to the corresponding aroma section. This signal triggers a small pump or atomizer within that section, which then releases a fine mist of the aligned scent into the immediate environment through a nozzle. This synchronized release of fragrance, alongside the visual content, creates a multi-sensory learning experience, enabling children to associate specific smells with objects and significantly enhancing memory retention and cognitive development through olfactory stimulation.

[0044] For interactive learning with letter units 122, a dedicated compartment 117 is installed within the body 101 that houses a vertical plate 118. Positioned along this vertical plate 118 are multiple horizontal sliders 119, which are specifically configured to securely hold and guide various letter units 122. Children slides these units along the plate 118 for interactive activities like spelling words or forming sequences.

[0045] To ensure the letter units 122 remain firmly in place during active learning and prevent any unintended movement, a C-shaped clamp 120 with a pincer arrangement 121 is strategically positioned behind each letter unit 122, facing its corresponding slider. When activated, this clamp 's pincer arrangement 121 engages to firmly grip the letter unit 122, thereby providing stability and allowing for focused interaction without accidental displacement.

[0046] The multiple horizontal sliders 119 are crucial for both securely holding and precisely guiding various letter units 122 within the dedicated compartment 117. Each slider is designed with a specific channel or groove that perfectly accommodates the base of a letter unit 122, ensuring a snug fit that prevents wobbling or accidental detachment. The inner surface of these channels, along with the corresponding contact points on the letter units 122, might be lined with low-friction materials or incorporate small, precisely engineered ridges to allow for smooth yet controlled movement.

[0047] For secure holding, the sliders 119 employ a form of friction fit or a subtle locking arrangement. This might involve a slightly tighter tolerance, or a design that subtly grips the letter unit 122 until a user applies a gentle force to slide it. When the child manipulates the letter unit 122, they apply force, and the slider, acting as a linear guide rail, allows the letter unit 122 to move freely along its designated horizontal path. The design of the slider ensures that the letter unit 122 maintains its upright orientation and alignment with the vertical plate 118, facilitating clear presentation and interaction. The collective action of these individual sliders 119 enables children to arrange the letter units 122 into various sequences or words for interactive learning activities.

[0048] The C-shaped clamp 120 with a pincer arrangement 121 is designed to provide a firm and reliable hold on the letter units 122 during learning activities, preventing any unintended movement. The "C-shaped" aspect allows it to wrap around a part of the letter unit 122 or its slider, providing a stable anchor. The core of its holding capability lies in the pincer arrangement 121. This typically involves two opposing gripping surfaces (the "pincers") that are brought together to apply compressive force on the letter unit 122.

[0049] When the clamp 120 needs to hold a unit, a small actuation arrangement (which includes but not limited to a miniature solenoid, a small motor, or a spring-loaded arrangement released by a latch) drives the pincers inwards. These pincers then press firmly against the sides or a designated gripping point of the letter unit 122. The C-shape often provides leverage, and the pincer arrangement 121 ensures a tight, secure grip. This mechanical locking action counteracts any forces that cause the letter unit 122 to slide out of position during a child's interaction, ensuring stability and allowing the child to focus on the learning task without frustration from displaced components. When the unit needs to be moved, the microcontroller signals the clamp 120 to release, retracting the pincers and freeing the letter unit 122. Crucially, a magnetic connection is disposed between each letter unit 122 and the clamp 120. This magnetic connection ensures the secure attachment of the units to the slider while simultaneously allowing for easy, controlled movement of the units along the plate 118. This design enables children to freely arrange the units into various letter sequences or word patterns without accidental displacement.

[0050] An audio output unit 125 is installed on the body 101, that is activated by the microcontroller to spell out words or sequences of letters by providing clear, specific verbal instructions. This unit, typically consisting of a speaker, receives digital audio signals from the microcontroller. The speaker works by converting the electrical signal into the audio signal. The speaker consists of a cone known as a diaphragm attached to a coil-shaped wire placed between two magnets. When the electric signal is passed through the voice coil, a varying magnetic field is generated by the coil that interacts with the magnet causing the diaphragm to move back and forth. The movement of the diaphragm pushes and pulls air creating sound waves just like the electrical signal received and used to spell out words or sequences of letters.

[0051] A storage unit 123, is strategically installed within the body 101, facilitates hands-on shape-learning activities using clay. Within this unit, multiple pneumatic frames 124 are arranged. Each of these frames 124 is pre-designed in a different, distinct geometric shape (e.g., square, circle, triangle, star). These frames 124 are essentially molds or tem plates. The extension and retraction of the frames 124 work in same manner as the telescopically operated leg disclosed above, powered by the pneumatic unit. When a specific shape-learning activity is initiated by the microcontroller accompanied by audio instructions from the audio output unit 125, the appropriate pneumatic frame is either presented to the child or its presence is highlighted. The child is then instructed to fill the pliable clay into the cavity 105 of the designated frame. The extension/ retraction of the pneumatic frame is regulated by the microcontroller by in the same manner as the telescopically operated legs 103, by employing the pneumatic unit, for secure the frame during filling, to assist in releasing the formed clay shape once it's complete. By providing a tangible boundary and outline, these frames 124 guide the child's motor skills, allowing them to press and spread the clay within the confined shape, thereby directly facilitating the formation of specific, accurate geometric shapes through tactile engagement. The imaging unit 104 continuously observes this process to ensure correct formation.

[0052] Lastly, a battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrode named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0053] The present invention work best in the following manner, where the body 101 equipped with multiple motorized wheels 102 for maneuverability within educational environments. The laser-based sensor to assess surface level and terrain, sending data to the microcontroller that activates telescopically operated legs 103 for stabilization. The artificial intelligence-based imaging unit 104 provides real-time monitoring of children’s activities, capturing, analyzing, and securely transmitting video feeds to authorized guardians’ computing unit to ensure engagement and safety. The extendable cavity 105 housing foldable plates 106 that automatically unfold into the L-shaped chair supported by telescopic rods 108 in the crisscross pattern, reverting to the stowed position upon deactivation. The writing pad 109 enabled for direct surface practice is complemented by the motorized two-axis slider 110 connected to the articulated robotic arm 111 via the telescopic bar 112 and ball-and-socket joint 113, with the robotic arm 111 designed to demonstrate proper pencil grip and hand movements, including gentle wrist guidance through the pressure sensors. The holographic projection unit 114 to display 3D educational visuals, fragrance spraying unit 115 releasing object-specific scents aligned with visual content, and the compartment 117 with the vertical plate 118 and multiple horizontal sliders 119 holding letter units 122, secured by C-shaped clamps 120 with pincers to ensure stability during interaction. Additionally, storage unit 123 with pneumatic frames 124 for shape-learning activities, the audio output unit 125 providing verbal instructions for clay-based shape formation, and the imaging unit 104 with facial recognition to identify children and personalize profiles. The GPS module enables location-based content adaptation aligned with local curricula, and the centralized database stores child profiles to facilitate personalized learning experiences.
