Description:FIELD OF THE INVENTION

[0001] The present invention relates to a multimodal illustration assistive device that is capable of enhancing user's creative process and skill development in both traditional and digital art forms through interactive features, automated feedback, and adaptable drawing surfaces.

BACKGROUND OF THE INVENTION

[0002] Assistance in learning styles and artistic is required to cater to diverse learning styles and artistic preferences. offers personalized guidance, automates error detection, and adapts to various drawing surfaces, ultimately accelerating skill development and expanding creative possibilities beyond single-medium limitations. Learning and practicing drawing often involves overcoming challenges like inconsistent practice, difficulty in identifying errors without expert feedback, and the limitations of single mediums. Access to varied drawing surfaces and personalized guidance is restrictive, hindering the development of diverse skills and creative exploration for aspiring artists.

[0003] Traditionally used devices for learning and developing drawing skills include pencils, charcoal, erasers, various types of paper, drawing boards, and physical reference materials. Problems arise when considering automation because these tools inherently lack digital interfaces for automated feedback, error detection, or guided instruction. Providing real-time corrections, tracking progress digitally, or offering dynamic learning modes directly through these physical tools is impossible without external, often cumbersome, setups like cameras and separate processing units. The tactile and immediate nature of traditional drawing, while beneficial, presents a barrier to seamless integration with automated learning means.

[0004] WO1999043235A1 discloses about the present invention relates to a drawing board, which provides an educational aid for children and adults, who wish to paint or draw a model, themselves or a subject, which board comprises two surfaces, on each of which a painting or a drawing of a subject which is positioned very close to the drawing board, will be done. Said surfaces belong to at least one transparent plate made of, e.g. glass, laminated glass or a plastic material, which is mounted in a holder device, which comprises at least one frame-like part, which has a relatively large depth and in substantially the center of which the transparent plate is mounted, said holder device, when used, being mounted in a substantially vertical direction, preferably transversal to horizontally directed support legs (runners) or the like, which are removably fastened to the lower ends of the vertical sides of the frame-like part in order to position the drawing board on a support, e.g. a floor or a table, the intention being to position the subject during the painting or the drawing in such a way that it will appear closely adjacent the plate and consequently appear in the surfaces, i.e. in the picture surfaces of the artist or the artists, i.e. in the surface, on which the picture is produced.

[0005] US5217376A discloses about an artist's drawing aid comprises a screen through which a three dimensional object can be observed. The screen is transparent allowing the object to be traced onto the screen using an eye piece to hold the eye position stationary. When traced, the object can be transferred to a translucent sheet of paper by placing the paper over the screen and by illuminating the screen through one edge so as to illuminate the traced lines. The screen is mounted on an easel construction with a shield above the screen. Edge illumination can be effected by a light bulb or by a cylindrical lens mounted on the edge of the screen and movable transversely of the edge to properly direct ambient light into the screen.

[0006] Conventionally, many devices have been available in market for assisting in learning and drawing art. However, these devices lack a multimodal approach necessary for comprehensive skill development. These devices often focus on a single medium or provide limited feedback means, failing to seamlessly combine traditional tactile drawing with the benefits of digital analysis, guidance, and adaptable means that cater to diverse learning preferences and artistic goals.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be capable of providing a comprehensive and adaptive illustration learning experience by integrating traditional drawing with digital feedback, offering diverse drawing surfaces, and providing personalized guidance through automated analysis and interactive means, thereby facilitating more effective skill development and creative exploration for users.

[0022] The present invention relates to a multimodal illustration assistive device that is capable of enhancing artistic creation and learning by providing a dynamic and interactive platform for both traditional and digital drawing, featuring automated feedback, adaptable drawing surfaces, and personalized guidance to empower users of all skill levels.

[0023] Referring to Figure 1, an isometric view of a multimodal illustration assistive device is illustrated, comprising a rectangular base 101 having four omnidirectional wheels 102 attached underneath the base 101 by means of cascading sliders 103, a rectangular plate 104 attached with the base 101, a barrel arrangement 105 mounted over the plate 104, an artificial intelligence-based imaging unit 106, installed on the base 101, a projection unit 107 mounted with the base 101 by means of an articulated link 108, a touch-enabled display panel 109 embedded in the plate 104, a clamp 110 holding a stylus 111 mount over the plate 104 by means of a translation arrangement 112, the plate 104 is supported over the base 101 at a rear portion by means of pivotally attached elongated flaps 113, a sliding unit 114 installed at each lateral edge of the plate 104, and having a clamp 115, a storage chamber 116 disposed at a front portion of the base 101, a microphone 117 and a speaker 118 attached on the base 101.

[0024] The device disclosed herein includes a rectangular base 101 is developed to be positioned on a flat surface. The base 101 herein incorporates all the components of the device required for assisting users with sketching, drawing, and note-taking. This device supports brainstorming sessions, dynamic teaching environments, and fostering of creative collaboration.

[0025] The base 101 is installed with a push button, accessed by the 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 communication module for establishing a wireless connection, which is linked with the microcontroller for establishing a wireless connection between the microcontroller and a computing unit (includes, but not limited to smartphone, tablet or laptop) and inbuilt with a user-interface that is accessed by the user to provide input commands to create a personalised profile, and interact to trigger a drawing mode and a learning mode, as well as switch between traditional and digital art functionalities.

[0027] 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.

[0028] Post receiving the input commands from the computing unit, the microcontroller processes the input commands and actuates a pivotally attached elongated flaps 113 located at the rear portion of the base 101 to allow a rectangular plate 104 arranged with the base 101 in a hinged manner, to serve as a drawing surface for the user. The pivotal attachment, facilitated by a hinge, enables the movement of the plate 104. The hinge used herein comprises of a pair of leaf that is screwed with the surfaces of the rectangular plate 104 and the base 101. The leafs are connected with each other by means of a cylindrical member integrated with a shaft coupled with a DC (Direct Current) motor to provide required movement to the hinge. The rotation of the shaft in clockwise and anti-clockwise aids in opening and closing of the hinge respectively. Hence, the microcontroller actuates the hinge that in turn provides movement to the flaps 113 for allowing the rectangular plate 104 to provide the drawing surface to the user, on which the user performs drawing activity.

[0029] When the user selects the drawing mode and a specific type of drawing sheet through the computing unit, the microcontroller actuates a barrel arrangement 105 holding a different types of drawing sheets and installed over the plate 104, to dispense the specified sheet over the plate 104. The barrel arrangement 105 comprises a central motorized shaft, acting as the core of the barrel arrangement 105. Arranged circularly around this shaft are multiple rollers, each holding a tightly wound spool of a distinct type of drawing sheet – perhaps one with smooth paper for fine lines, another with textured paper for charcoal, and yet another with thicker stock for painting. When the user selects the specific type of drawing sheet, the microcontroller signals the motorized shaft. This shaft then rotates, engaging the roller that holds the desired sheet. As the shaft turns, it unwinds a portion of the drawing sheet from its spool. This unwound section is then guided over the rectangular plate 104 for providing a fresh surface for the user to create their artwork. The arrangement 105 ensures that only the selected sheet is dispensed, keeping the other types neatly stored and ready for future use.

[0030] Once the sheet is dispensed over the plate 104, the microcontroller actuates a sliding unit 114 installed at each lateral edge of the plate 104 to enable a clamp 115 configured with the sliding unit 114, to gripping the dispensed sheet. The sliding unit 114 consists of a pair of sliding rails fabricated with grooves in which the wheel of a slider is positioned that is further connected with a bi-directional motor via a shaft. The microcontroller actuates the bi-directional motor to rotate in a clockwise and anti-clockwise direction that aids in the rotation of the shaft, wherein the shaft converts the electrical energy into rotational energy for allowing movement of the wheel to translate over the sliding rail by a firm grip on the grooves. The movement of the sliding unit 114 results in the translation of the clamp 115 over the plate 104 for securing the dispensed sheet over the plate 104.

[0031] Once the clamps 115 are aligned with the dispensed sheet, the microcontroller actuates the clamps 115 to secure the dispensed sheet. The clamps 115 is powered by a DC (direct current) motor that is actuated by the microcontroller by providing required electric current to the motor. The motor comprises of a coil that converts the received electric current into mechanical force by generating magnetic field, thus the mechanical force provides the required power to the clamps 115 thus extending and retracting for gripping the dispensed sheet. Once the dispensed sheet is secured, the user accesses a storage chamber 116 at the front of the base 101 to take out drawing tools stored in the chamber 116 and begin creating art on the sheet.

[0032] Once the user finishes their artwork and selects a finish option available on the computing unit. The microcontroller then processes the user’s input command and activates an artificial intelligence-based imaging unit 106 mounted on the base 101, to capture multiple images in the vicinity of the artwork to analyze the user's drawing and identify potential errors. The imaging unit 106 comprises of an image capturing module including a set of lenses that captures multiple images in vicinity of the base 101 of the artwork drawn by the user on the drawing sheet, and the captured images are stored within memory of the imaging unit 106 in form of an optical data.

[0033] The imaging unit 106 also comprises of a processor that is encrypted with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller. The microcontroller processes the received data and determines errors in the drawn art of the user.

[0034] Upon detecting potential errors in the user’s artwork, the microcontroller then stores the user's captured artwork along with the identified errors in a data base 101 linked to the microcontroller, and activates an analysis module configured with the microcontroller, to analyze the stored data to evaluate trends in the user's drawing performance, identifying improvements or declines in their drawing skills over time. The analysis module is a computational unit and is designed to assess the user's drawing performance over time by analyzing stored artwork data and associated error records.

[0035] The module comprises a data retrieval interface, a feature extraction unit and a trend analysis engine. Upon activation, the data retrieval interface accesses historical artwork records and corresponding error metrics stored in the data base 101. The feature extraction unit processes each artwork to identify quantifiable attributes such as line accuracy, symmetry, shape proportions, stroke consistency, and frequency or type of errors. These features are then fed into the trend analysis engine, which employs statistical models and/or machine learning protocols—such as regression analysis or classification models—to detect patterns of improvement or decline in the user’s drawing skills over sequential sessions.

[0036] The final analysis results are compiled and displayed on the computing unit, which visually present charts or summaries indicating areas of strength and those needing improvement. This feedback helps the user to monitor artistic development in a structured, data-driven manner.

[0037] Once the user reviews the identified areas for improvement on the computing unit and issues a command for guidance, then the microcontroller activates an articulated link 108 mounted on the base 101 to translate and position a projection unit 107, which is attached to the arm’s end, directly over the portion of the user's artwork containing the detected errors. The articulated link 108 comprises of multiple joints and segments connected through rotary and/or prismatic joints, forming a multi-degree-of-freedom mechanical arm. Each joint is actuated by a combination of servo motors, stepper motors, or linear actuators, depending on the required type of movement—rotational or linear, thus allowing for flexible and precise movement in multiple directions. Upon detection of errors in specific portions of the user’s artwork, the microcontroller calculates the corresponding spatial coordinates and drive the actuators, causing the articulated segments to adjust their orientation and extension dynamically.

[0038] Once the projection unit 107 is positioned over the target area of the drawing, then the microcontroller activates the projection unit 107 to overlay visual indicators or correction guides directly onto the error portion for allowing the user to guide the user with techniques for avoiding the errors detected by the imaging unit 106. The projection unit 107 is a compact optical unit designed to project visual indicators, such as highlights, outlines, or correction guides, directly onto the surface of the drawing where the error is detected. The projection unit 107 comprises several key components: a digital light processing (DLP) or liquid crystal display (LCD) based light engine, a high-intensity LED or laser diode as the light source, projection optics including adjustable lenses, and a control processor.

[0039] When the microcontroller determines the coordinates of the error region, this data is sent to the projection unit’s 107 control processor, which interprets the coordinates and generates a corresponding correction image or guide from stored templates or dynamically rendered graphics. The light engine processes this image and, in coordination with the projection optics, projects it onto the precise area of the artwork.

[0040] In the event that the user selects the option to create digital art via the computing unit, the microcontroller activates a touch-enabled display panel 109 integrated into the plate 104 to allow the user to draw and interact directly on the screen to produce digital artwork. The touch-interactive display panel 109, as mentioned herein, is typically an LCD (Liquid Crystal Display) screen that presents output in a visible form. The screen is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers or a stylus 111 arranged with the plate 104. The panel includes a touch controller IC (Integrated Circuit) that processes the analog signals generated when the user provides input through touch gestures.

[0041] This touch controller is typically connected to an embedded microcontroller within the device via communication interfaces such as SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit). Upon receiving the input commands, the touch controller sends the processed data to the microcontroller in the form of electrical signals. The microcontroller then interprets the data and renders the corresponding digital artwork or modifications on the screen. The display panel 109, in conjunction with the microcontroller, ensures real-time response and high precision in the user's drawing actions, while providing an intuitive and seamless digital art creation experience.

[0042] A clamp 110 holds the stylus 111 mount over the plate 104 using a translation arrangement 112, providing practical guidance for digital art drawing. The microcontroller actuates the clamp 110 for enabling the user to position the stylus 111 and perform digital art drawing in the drawing mode. The stylus 111 functions as a precise input device used to interact with the display panel 109. When the user draws with the stylus 111, it interacts with the screen using either capacitive or resistive touch technology. In capacitive screens, the stylus 111, often made of conductive material, alters the screen's electric field, allowing the display panel 109 to detect the location of the contact. In resistive screens, the stylus 111 applies pressure to the surface, registering contact through physical layers.

[0043] The stylus 111 include pressure sensitivity, enabling the user to control the thickness and opacity of strokes based on the force applied. In an embodiment of present invention, this is made possible through pressure sensors in the stylus 111 that measure pressure, which are then interpreted by the microcontroller to adjust the drawing accordingly. Additionally, the stylus 111 support tilt sensitivity, allowing the user to angle the stylus 111 and simulate effects similar to traditional brushes or pens. The stylus 111 communicates wirelessly with the device, often via Bluetooth or electromagnetic resonance (EMR), to send position and pressure data to the microcontroller. This data is then processed by the microcontroller, which renders the corresponding strokes or shapes on the screen in real-time, allowing for an intuitive and responsive digital drawing experience.

[0044] The pressure sensor within the stylus 111 functions by detecting the force exerted by the user's hand pressing the stylus 111 tip against the display panel 109. This force causes a physical change within the sensor, often a deflection of an internal diaphragm or a change in the electrical resistance of a pressure-sensitive material. This physical change is then converted into a corresponding electrical signal. The stronger the pressure applied, the greater the change in the sensor and consequently, the stronger the electrical signal generated. This electrical signal is then transmitted to the microcontroller. The microcontroller interprets the varying strength of this signal as different levels of pressure, which it then translates into variations in the thickness and opacity of the digital strokes rendered on the display. For instance, a stronger signal (indicating higher pressure) might result in a thicker and more opaque stroke, while a weaker signal (lower pressure) produces a thinner and more transparent line.

[0045] In learning mode, the microcontroller simultaneously actuates the clamp 110 and the translation arrangement 112 to guide the stylus 111 in drawing digital art directly on the touch-enabled display panel 109. The clamp 110 securely holds the stylus 111 in a fixed orientation, while the translation arrangement 112 comprises a motorized pulley containing a spool of cable coupled at each of the four corners of the plate 104. A carriage, which holds the clamp 110 securing the stylus 111, is connected to the four ends of these cables. Each motorized pulley is individually controlled and selectively actuated by the microcontroller, allowing for coordinated winding and unwinding of the cable’s controls. By adjusting the tension and length of each cable, the microcontroller precisely positions and repositions the carriage over the plate 104 in two-dimensional space (X and Y axes).

[0046] The microcontroller processes predefined drawing paths or instructional patterns stored in the database and converts them into movement commands for the translation arrangement 112. As the arrangement 112 operates, the stylus 111 moves smoothly over the display panel 109, replicating accurate lines, shapes, or strokes according to the stored guidance data. This coordinated action allows the device to demonstrate drawing techniques or assist users by tracing digital content directly on the screen for providing a hands-on visual learning experience. The user observes the stylus 111 in motion and follow along, making it easier to understand and replicate drawing patterns and improve their skills over time. The clamp 110 used herein for holding the stylus 111 works in same manner as the clamp 115 mentioned above.

[0047] A microphone 117 is installed on the base 101, that is activated by the microcontroller to enable user to interact via voice regarding required guidance with drawing and switching to a specific mode. The microphone 117 contains a small diaphragm connected to a moving coil. When sound waves of the user hit the diaphragm, the coil vibrates. This causes the coil to move back and forth in the magnet's field, generating an electrical current. The signal of which are sent to the microcontroller for processing the input voice command of the user regarding required guidance with drawing and switching to the specific mode.

[0048] When the user switches to the learning mode via the microphone 117, the microcontroller actuates a speaker 118 installed on the base 101, which works in conjunction with the stylus 111, by providing audible guidance to the user for offering practical instruction for digital art drawing. The speaker 118 functions by converting electrical signals into audio signals. The speaker 118 comprises a cone, known as a diaphragm, attached to a coil-shaped wire (voice coil) positioned between two magnets. When an electrical signal passes through the voice coil, it generates a fluctuating magnetic field that interacts with the permanent magnets. This interaction causes the diaphragm to vibrate back and forth, pushing and pulling the surrounding air to create sound waves that correspond to the electrical signal and guide the user.

[0049] When the user desired to reposition the device as per requirement and input commands via the computing unit, the microcontroller then processes these user commands and actuates four omnidirectional wheels 102 attached underneath the base 101 by means of cascading sliders 103, to reposition the base 101. The omni-directional wheels 102, also known as an omni-wheel, consists of a central hub with multiple small, freely-rotating rollers mounted around its circumference. These rollers are angled relative to the wheel's axis, allowing the wheel to move smoothly in any direction without changing its orientation. When the central hub rotates, the rollers' angled design permits lateral movement across different axes, enabling the device to travel forward, backward, or sideways with ease as per the requirement. Thus reposition the device as per requirement.

[0050] In case the user desires to adjust the device height and input commands via the computing unit, then the microcontroller actuates the cascading sliders 103 to adjust the height of the device as per the requirement. The cascading sliders 103 operate by using a series of interconnected sliders 103 that move in a controlled sequential manner to extend or retract to adjust the height of the device. When activated by the microcontroller, it sends an electrical signal to the first slider. This signal triggers a motor or actuator, typically a stepper motor or servo motor, which is connected to the first slider. The motor initiates the movement of the first slider along its designated track or rail; thus, the first slider begins to move, triggering the next slider in the sequence, thus cascading the motion progressively. Each slider is developed to smoothly slide over the previous one for ensuring that the device’s height adjust with precision and stability.

[0051] 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.

[0052] The present invention work best in the following manner, where the rectangular base 101 configured to rest on the flat surface for assisting with sketching, drawing, note-taking, and digital art creation. The microcontroller manages device functions by communicating with the computing unit via the Wi-Fi-based communication module. Upon receiving commands form the computing unit the microcontroller actuates the hinge associated with the elongated flap for enabling the rectangular plate 104 to rise and function as the drawing surface. The barrel arrangement 105 with the central motorized shaft rotates to dispense the selected drawing sheet, which is secured using the clamps 115 actuated by microcontroller and positioned through the sliding unit 114. The storage chamber 116 stored with the drawing tools is accessed by the user to draw artwork on the sheet. The imaging unit 106 captures images of the drawing to detect and store errors in the database, which are then analyzed by the analysis module. Based on analysis, the articulated link 108 positions the projection unit 107 to overlay visual correction guides. In digital mode, the microcontroller activates the touch-enabled display panel 109 and guides the stylus 111 via the clamp 110 and the translation arrangement 112. The user’s voice commands are processed using the microphone 117, while instructions are delivered through the speaker 118. The mobility and height adjustment are enabled by omnidirectional wheels 102 and cascading sliders 103 actuated by the microcontroller.

[0053] Although the field of the invention has been described herein with limited reference to specific embodiments, this description is not meant to be construed in a limiting sense.
