Description:FIELD OF THE INVENTION

[0001] The present invention relates to a student assistant device for scholastic improvement that provides personalized learning experiences and real-time feedback to a student for improving academic performance by the help of automated assessment and grading which in turn analyses the student's learning behaviour and provide suitable recommendations for enabling the students to achieve better academic outcomes.

BACKGROUND OF THE INVENTION

[0002] A student's learning journey is a path that requires personalized support for achieving academic success. Students having learning gaps such as difficulty in understanding concepts, lack of clarity on specific topics, etc. are required to be under immediate guidance to improve their understanding and prevent them from falling behind. In such case, a concerned educator is required to provide individual attention to the student. Although, there might be chances of unavailability of educators during such critical learning moments, especially in overcrowded classrooms. In such case, the student is required to rely on personal learning resources. But personal learning resources do not have real-time feedback mechanisms for tracking the student's progress and the student is also not enough aware of their own learning gaps that sometimes results in worsening the student's performance or academic failure.

[0003] Sometimes, depending on the student's location (home/school) where educational support is to be reached, there are chances of delayed access to resources. Basically, a reasonable time is provided for the students to access learning materials. But due to lack of digital infrastructure and limited access to quality educational content, the learning time could vary from hours to days or even weeks. Because of lack of efficient learning management systems, it leads to loss of valuable learning time due to students not being able to access relevant resources and support.

[0004] However, delayed access to educational resources becomes a major obstacle for students to receive timely guidance that may worsen the student's performance, in this case the student also needs to rely on personal learning initiatives. However, while relying on personal learning initiatives there are chances of facing difficulties in understanding complex concepts and lack of clarity on specific topics while studying, which also leads to delay in achieving academic milestones. Moreover, the educator's authority is not aware regarding the student's learning gaps, and hence, the student is not provided with targeted support based on their needs.

[0005] US20110129808A1 discloses a 360° learning system wherein the system is creating the next-generation education system, a self-managed learning ecosystem, a personalized learning context for each learner, by enabling a uniquely integrated and comprehensive digital content and process platform that has 360° span of association with respect to individual users, institutional users, domain, enablement, access, benefits and hardware (including a dedicated ‘PDA’ optimized for learning purposes to be an optional access device for students). Although US’808 discloses a 360° learning system that provides a personalized learning context for each learner. However, this disclosed system lacks in providing real-time feedback and assessment, which are essential for identifying knowledge gaps and providing targeted support.

[0006] US20060136243A1 discloses an apparatus and method for administering a scholastic application program. An electronic transcript of a candidate is received by a clearinghouse from a school. The candidate selects one or more institutions and instructs the clearinghouse to transmit the electronic transcript to the institutions for the purpose of a screening review. The institutions receive the electronic transcript and perform automated reviews of the electronic transcript using pre-determined criteria. If the candidate satisfies the predetermined criteria for an institution, the candidate is invited to apply for admission by the institution. Though US’243 discloses an apparatus and method for administering a scholastic application program and streamlines the application process, however it does not provide any means for real-time guidance and support to students during their learning journey.

[0007] US2014255889A1 discloses a gateway system for providing a comprehensive integrated education system. It is implemented through a cloud-computing platform, linking together learning and assessment systems, which provide learning, education, and evaluation services for a user, and reward systems, which provide rewards for a user for successfully completing learning and education processes, which are connected to the cloud-computing platform. In some embodiments, a user is a student, and a desired reward is access to certain features on the student's electronic computing device. The gateway system ensures that the student correctly answers certain test questions which have been appropriately chosen before unlocking those features. Although US’889 discloses a gateway system for providing a comprehensive integrated education system. While this system rewards students for completing learning processes, it does not provide real-time analysis of student performance, which is crucial for identifying areas where students need additional support.

[0008] As per the discussion in above-mentioned prior arts, many methods and systems are available that are focused on providing personalized learning experiences to students. However, these conventional systems and methods don’t deliver real-time feedback and support to students during their learning journey due to limitations in automated assessment and grading mechanisms. These systems also don’t adapt to individual learning styles and abilities due to which students who require extra support are not identified and assisted on time, resulting in learning gaps and decreased academic outcomes.

[0009] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to be equipped with a provision of managing personalized learning experiences for students, along with providing real-time feedback and assessment, to facilitate timely identification of learning gaps and knowledge deficits. The developed device should also prioritize students based on their individual learning needs and abilities, by sharing relevant learning analytics and insights with faculty in a secure and efficient manner, to provide targeted support and interventions for improved academic outcomes.

[0028] 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.

[0029] The present invention relates to a student assistant device for scholastic improvement that is capable of facilitating personalized learning based on the learning gaps faced by the student. Additionally, the proposed device also analyses emotional and cognitive states of the student in real-time along with notifying a faculty regarding student's difficulty levels to prioritize the student in academic support to prevent lag in student's academic progress, thereby providing appropriate support to the students on time.

[0030] Referring to Figure 1 and 2, an isometric view of a cuboidal body associated with a student assistant device for scholastic improvement and an inner view of a cuboidal body associated with the proposed device are illustrated, comprising a cuboidal body 101, a first artificial intelligence-based imaging unit 102 mounted on the body 101, a second artificial intelligence-based imaging unit 103 installed on the body 101, a touch enabled screen 104 installed on the body 101, a sheet dispensing module 201 installed with the body 101, the sheet dispensing module 201 comprises of a motorized roller 202 installed within the chamber 203 via an L-shaped bar 204, and a telescopically operated gripper 105 arranged on the body 101, a printing unit 106 installed on the body 101 via an L-shaped link 107, a motorized slider 108 is configured with the link 107.

[0031] Figure 1 and 2 further illustrates a speaker 109 mounted on the body 101, a scanning module 205 configured within a container 208 arranged within the body 101, the scanning module 205 includes a camera 206 and an OCR (Optical Character Recognition) module 207, a microphone 110 is arranged on the body 101, plurality of pneumatic blocks 111 arranged on a plate 112 attached with the body 101, a platform 113 attached with the body 101, a braille script printing module 115 installed on the platform 113 via an L-shaped rod 114, the braille script printing module 115 includes a rectangular member 116 arranged with plurality of hollow pneumatic pins 117, connected with an ink vessel 118 via plurality of conduits 119, and an iris pore 120 equipped with each of the pins 117 and a slit 121 carved on the chamber 203.

[0032] The device disclosed herein comprises a cuboidal body 101 that serves as the primary structural component of the device, specifically designed to be utilized by educational institutions to facilitate scholastic improvement among students. The body 101 is positioned atop each desk within the institutional enclosure and operated by the students. Initially, the student presses a push button installed on the body 101 to activate the device. The push button typically consists of a button cap which is the visible rounded part of the button that the user presses.

[0033] When the user pushes the push button, it pushes down a plunger, which is a small rod or a cylinder. Inside the push button, there are electrical contacts made of electrical materials like metal. When the user presses the push button, it completes the electrical circuit, allowing current to flow and triggering an inbuilt microcontroller’s operation, which is associated with the device. The microcontroller functions as a central processing unit of the device, executing programmed instructions to control its operations, manage inputs and outputs, and coordinate various components for seamless functionality.

[0034] Activation of the microcontroller enables a first artificial intelligence-based imaging unit 102, mounted on the body 101, to capture multiple images of a writing board installed within the enclosure, thereby monitoring the subject, topic, and standard of the subject being taught to the student. The artificial intelligence-based imaging unit 102 is constructed with a camera lens and a processor, wherein the camera lens is adapted to capture a series of images of the board.

[0035] The processor carries out a sequence of image processing operations including pre-processing, feature extraction, and classification by utilizing artificial intelligence and machine learning protocols. The images captured by the imaging unit 102 are real-time images of the board. The artificial intelligence-based imaging unit 102 transmits the captured image signal in the form of digital bits to the microcontroller. The microcontroller upon receiving the image signals compares the received image signal with the pre-fed data stored in a database and constantly determines the subject, topic, and standard of the subject being taught to the students.

[0036] Based on the detected subject, topic, and standard of the subject being taught to the students, the microcontroller initiates a second artificial intelligence-based imaging unit 103, paired with a processing unit installed on the body 101, to detect the facial expression of the student while being taught on the writing board. Upon detecting a facial expression indicative of difficulty in understanding, the microcontroller, with the help of the first imaging unit, identifies the subject and topic being taught and stores relevant information in the database.

[0037] A touch enabled screen 104 is integrated into the body 101, allowing students to input commands for self-evaluation examinations. The touch enabled screen 104 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 principle, allowing the user to interact directly with the display using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user input commands for self-evaluation examinations.

[0038] The touch controller is typically connected to the microcontroller through various interfaces which may include but are not limited to PI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit). Upon receiving these input commands, the microcontroller processes them and accesses the database to retrieve the subject and topic with which the student is experiencing difficulty. Subsequently, the microcontroller fetches relevant questions to facilitate the student's better understanding of the subject matter.

[0039] Concurrently, the microcontroller actuates a sheet dispensing module 201, which is integrated into the body 101 to dispense a sheet from a chamber 203 housed within the body 101 and position the sheet over the body 101. The sheet dispensing module 201 comprises a motorized roller, arranged inside the chamber 203 via an L-shaped bar 204, and a telescopically operated gripper 105 installed on the body 101. The roller, in contact with the sheets placed in the chamber 203, rotates to transfer a sheet out of the chamber 203 through a slit 121 carved on the chamber 203. Internally, the motorized roller 202 comprises a DC motor, gearbox, and roller 202 shaft.

[0040] The DC motor provides the rotational force, while the gearbox adjusts the speed and torque to optimize sheet transfer. The roller 202 shaft, connected to the gearbox, rotates in contact with the sheets, transferring them out of the chamber 203. As the roller 202 rotates, it pushes the sheet out of the chamber 203, where it is then grasped by the telescopically operated gripper 105. The gripper 105 consists of a linear actuator, gears, and a clamp. The linear actuator provides the telescoping motion, while the gears adjust the speed and force. The clamp, connected to the gears, securely grasps the sheet, holding it in place.

[0041] Once the gripper 105 has secured the sheet, the microcontroller directs a printing unit 106, which is installed on the body 101 via an L-shaped link 107, to print the fetched questions over the sheet. The printing unit 106 comprises a print head, ink reservoir, and paper handling mechanism. The print head, containing tiny nozzles, deposits ink onto the sheet, creating the printed text. The ink reservoir supplies the ink to the print head, while the paper handling mechanism ensures proper sheet alignment and feeding.

[0042] To facilitate accurate printing, a motorized slider 108 is configured with the link 107, allowing it to translate the link 107 along with the printing unit 106. The motorized slider 108 consists of a stepper motor, lead screw, and slider 108 carriage. The stepper motor provides precise rotational motion, while the lead screw converts this motion into linear movement. The slider 108 carriage, connected to the lead screw, moves the printing unit 106 along the sheet, ensuring accurate printing of questions across the entire sheet.

[0043] Upon completion of printing the questions on the sheet, the microcontroller initiates an audible notification via a speaker 109 integrated into the body 101, instructing the student to commence solving the questions. The speaker 109 is capable of producing clear and natural sound and is capable of adjusting its volume based on ambient noise levels. The speaker 109 consists of audio information, which is in the form of recorded voice, synthesized voice, or other sounds, generated or stored as digital data.

[0044] This data is often in the form of an audio file. The digital audio data is sent to a digital-to-analog converter (DAC). The DAC converts the digital data into analog electrical signals. The analog signal is often weak and needs to be amplified. An amplifier boosts the strength to a level so that the speaker 109 drives it effectively. The amplified audio signal is then sent to the speaker 109. The core of the speaker 109 is an electromagnet attached to a flexible cone. These sound waves travel through the air as pressure waves and are picked by the user’s ear.

[0045] Concurrently, the microcontroller directs the display screen to present a countdown timer, indicating the allotted time duration within which the student must complete the questions. During the examination, an eye-gaze detection sensor is integrated into the body 101, operating in sync with the second imaging unit to detect any unfair means employed by the student. The eye-gaze detection sensor employs artificial intelligence and machine learning protocols to track the student's eye movements and detect any irregularities.

[0046] Internally, the eye-gaze detection sensor consists of a high-resolution camera, infrared (IR) illuminators, and a processing unit. The camera captures images of the student's eyes, while the IR illuminators provide additional lighting to enhance the image quality. Upon detection of such irregularities, the eye-gaze detection sensor triggers an alert notification, which is transmitted to faculty's computing unit, thereby notifying the faculty of the unfair means utilized by the student.

[0047] The processing unit analyses the captured images to detect the student's eye movements, which is achieved through various techniques, including pupil detection, gaze estimation, and eye-tracking. The protocols then process the images in real-time, enabling the sensor to accurately track the student's eye movements and detect any suspicious behaviour. To detect unfair means, the sensor recognizes specific patterns of eye movement that are indicative of cheating. For instance, if the student's eyes are consistently moving towards a particular region, such as a hidden note or a fellow student's paper, the sensor detects this anomaly and trigger an alert notification to the faculty's computing unit, thereby preventing cheating and maintain the integrity of the examination process.

[0048] Upon completing their responses to the questions, the student is required to submit their answer sheet within a container 208 integrated into the body 101. A scanning module 205, installed within the container 208, subsequently scans the submitted sheet. The scanning module 205 comprises a camera 206 and an OCR (Optical Character Recognition) module 207, which collaboratively scan the sheet to extract the answers provided by the student. The camera 206 captures high-quality images of the submitted answer sheet. Internally, the camera 206 consists of a lens, image sensor, and processor.

[0049] The lens focuses light onto the image sensor, which converts the light into electrical signals. These signals are then processed by the camera’s 206 processor, which adjusts parameters such as brightness, contrast, and noise reduction to optimize the image quality. Once the camera 206 captures the image, it is transmitted to the OCR module 207 for processing. The OCR module 207, comprising artificial intelligence and machine learning protocols, is designed to recognize and extract text from the captured image.

[0050] Internally, the OCR module 207 employs a multi-step process, including image pre-processing, text recognition, and post-processing. During image pre-processing, the OCR module 207 applies filters to remove noise, correct skewing, and enhance the image quality. The text recognition stage involves the OCR module 207 analyzing the pre-processed image to identify patterns and features that correspond to specific characters. This is achieved through protocols, such as neural networks and machine learning, which enable the OCR module 207 to learn and adapt to different font styles, sizes, and languages. Once the text is recognized, the OCR module 207 proceeds to the post-processing stage, where it corrects errors, formats the text, and extracts relevant information.

[0051] In a synchronized manner, the camera 206 and OCR module 207 work together to extract answers from the submitted answer sheet. As the camera 206 captures images of the sheet, the OCR module 207 processes these images in real-time, recognizing and extracting text to determine the student's answers. The synchronized operation of the camera 206 and OCR module 207 enables accurate and efficient scanning of answer sheets, facilitating the evaluation of student performance.

[0052] Following the scanning process, the microcontroller compares the student's responses with pre-stored answers in the database, enabling the evaluation of the student's score. The assessed score, accompanied by a detailed analysis of the student's answer sheet, is then displayed on the screen for review.

[0053] In the event that the evaluated score falls below a predetermined threshold value, the microcontroller transmits an alert notification to the faculty's computing unit, prompting the faculty to provide supplementary instruction to the student such as providing extra classes to the student, wherein the computing unit is wirelessly linked with the microcontroller via a communication module, facilitating the establishment of a wireless connection between the microcontroller and the subject faculty's computing unit. The communication module includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module.

[0054] In scenarios where the student is visually impaired or blind, then the student needs to provide voice commands over a microphone 110 integrated into the body 101, regarding their vision impairment. The microphone 110 plays a crucial role by converting spoken words or commands into electrical signals which are then processed and analyzed to trigger specific actions. When the user speaks or commands for securing the platform 113 with the wheel guard of the grinding machine, their vocal cords vibrate, creating sound waves. These sound waves travel through the air as variations in air pressure.

[0055] The microphone 110 mentioned herein is a transducer that converts these variations in air into electric signals. The analog electrical signal is converted into digital form which is done by an analog-to-digital converter (ADC). The digital signal is then subjected to various signal processing techniques to enhance voice quality and eliminate noise. In response to these voice commands, the microcontroller actuates a plurality of pneumatic blocks 111 arranged on a plate 112 attached to the body 101. The pneumatic blocks 111 extend and retract to form a Braille script corresponding to the topic being taught on the writing board. The extension of the block in powered by a pneumatic unit that utilizes the compressed air to extend or retract the block to form braille script.

[0056] The process begins with an air compressor which compresses atmospheric air to a higher pressure. The air cylinder of the pneumatic unit contains a piston that moves back and forth within the cylinder. The cylinder is connected to one end of the blocks 111. The piston is attached to the blocks 111 and its movement is controlled by the flow of compressed air. To extend the blocks 111 the piston activates the air valve to allow compressed air to flow into the chamber 203 behind the piston. As the pressure increases in the chamber 203, the piston pushes the blocks 111 to the desired length to form braille script and this functionality allows the visually impaired student to comprehend the subject matter by tactilely exploring the Braille script through finger movement over the blocks 111.

[0057] Each of the pneumatic blocks 111 are equipped with a touch sensor, which detects a pause in the student's movement, indicating potential difficulty in understanding the topic being taught. The touch sensor employed on each pneumatic block is a type of capacitive sensor, which detects changes in capacitance caused by the student's touch. Internally, the touch sensor consists of a sensor electrode, a dielectric material, and a processing unit. The sensor electrode is a conductive material that forms one plate 112 of a capacitor, while the dielectric material separates the sensor electrode from the student's body 101.

[0058] When the student's finger comes into proximity with the pneumatic block, their body 101 acts as a second plate 112 of the capacitor, forming a capacitance with the sensor electrode. The processing unit, which is connected to the sensor electrode, detects the change in capacitance caused by the student's touch. This change in capacitance triggers a signal, which is then processed by the microcontroller to determine the student's interaction with the block. The processing unit employs machine learning protocols to filter out noise and detect the precise moment when the student's finger touches or pauses on the block.

[0059] This information is then transmitted to the microcontroller, which interprets the data to determine the student's understanding of the topic being taught. Upon detecting such a pause, the microcontroller retrieves relevant questions for the student to solve and generates a corresponding Braille script to be printed, thereby providing additional support and clarification to facilitate the student's comprehension.

[0060] Subsequently, the blind student is required to provide voice commands through the microphone 110 to initiate a self-evaluation examination. Upon receiving voice commands from the blind student to initiate a self-evaluation examination, the microcontroller activates the sheet dispensing module 201, which dispenses a sheet and positions it on a platform 113 attached to the body 101. Simultaneously, the microcontroller actuates a braille script printing module 115, which is mounted on the platform 113 via an L-shaped rod 114, to print the predetermined Braille script on the sheet, which enables the student to comprehend the questions and provide answers on a separate sheet, which is also dispensed through the sheet dispensing module 201.

[0061] The Braille script printing module 115 comprises a rectangular member 116 equipped with a plurality of hollow pneumatic pins 117, which are connected to an ink vessel 118 via multiple conduits 119, which supply ink to the pins 117 as needed. Each pin is fitted with an iris pore 120, and these components work in tandem to print the Braille script. The rectangular member 116 of the braille script printing module 115 serves as the foundation for the printing mechanism. It provides a stable surface for the hollow pneumatic pins 117, which are arranged in a specific pattern to correspond to the Braille script.

[0062] The iris pore 120 equipped with each pin helps in printing the Braille script. When the pin is actuated, the iris pore 120 opens, allowing ink to flow onto the sheet. The extension of the pin is powered by a pneumatic unit that utilizes the compressed air to extend or retract the pins 117. The iris pore's 120 precise control over ink flow ensures that the Braille dots are printed accurately and consistently. As the pins 117 move up and down, the iris pores 120 open and close in synchronization, creating the raised Braille dots on the sheet.

[0063] Additionally, the microcontroller actuates a motorized sliding unit integrated with the L-shaped rod 114, providing a precise to-and-fro motion to the rod 114 and the Braille script printing module 115, which enables accurate printing of the Braille script onto the sheet. The motorized sliding unit consists of a motor, and a rail unit integrated with ball bearings to allow smooth linear movement. As the motor rotates the rotational motion of the motor is converted into linear motion through a pair of belts and linkages. This linear motion provides a stable track and allows the rod 114 to move in to-and-fro motion for printing the braille script onto the sheet, thereby ensuring that the Braille script is printed correctly, with precise control over the spacing, alignment, and formatting of the Braille dots, thus facilitating scholastic improvement among students.

[0064] A battery 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.

[0065] The present invention works best in following manner, where the cuboidal body 101 as disclosed in the invention is placed on the student's desk in the educational institute and process begins by capturing images of the writing board through the first artificial intelligence-based imaging unit 102. The images are then processed to detect the subject, topic, and standard of the lesson being taught. This information is saved in the linked database for future reference. As the lesson progresses, the second artificial intelligence-based imaging unit 103 detects the student's facial expression. If the microcontroller determines that the student is having difficulty understanding the material, then it accesses the database to fetch the subject and topic being taught and saves information regarding the student's difficulty. The student uses touch-enabled screen to give input commands for the self-evaluation examination. The microcontroller processes the input commands and accesses the database to fetch questions tailored to the student's needs. The questions are then printed on the sheet dispensed by the sheet dispensing module 201. The student then attempts to answer the questions on the sheet. Once completed, the student manually places the answer sheet in the scanning module 205. The module scans the sheet and the microcontroller compares the answers with pre-saved answers stored in the database. The student's score is then evaluated and displayed on the screen along with the detailed analysis of their answer sheet.
