Description:FIELD OF THE INVENTION

[0001] The present invention relates to a vehicle seat-mounted entertainment and user comfort management device that is capable of enhancing passenger experience by providing interactive media access, personalized comfort features, posture guidance, environmental adaptability, health monitoring, and dynamically adaptive automated adjustments during travel.

BACKGROUND OF THE INVENTION

[0002] With the increasing duration of travel and demand for in-transit productivity and relaxation, there is a growing need for vehicle seat-mounted entertainment and user comfort means. Passengers often seek personalized and interactive experiences to make travel more enjoyable and less fatiguing. However, several challenges persist, including improper screen alignment, poor posture during long journeys, exposure to sunlight glare, lack of privacy, and limited adaptability of current means to environmental or user-specific conditions. Moreover, detecting and addressing user discomfort or motion sickness in real time remains largely unaddressed. Existing solutions often lack integration of automated features that adapt dynamically to user needs, making travel less comfortable and potentially stressful, especially on long or physically demanding journeys.

[0003] Traditionally available in-vehicle entertainment means include fixed-back seat screens, basic media players, and standard audio units that offer limited interactivity and user control. These measures typically lack adaptability to individual user preferences, environmental conditions, or ergonomic requirements. Most are not adjustable to the user’s line of sight, leading to discomfort during prolonged viewing. Privacy is also a concern, as content is visible to nearby passengers. Additionally, traditional means do not provide features like posture guidance, motion sickness detection, or environmental adaptation based on light and noise levels. They are static, non-responsive, and do not offer personalized content or health-focused features, making them insufficient for modern travel demands centered around comfort, wellness, and real-time user interaction.

[0004] US8141948B2 discloses about a seat back entertainment system includes a seat panel connected to a frame of a vehicle seat. A video unit provides a video signal. A display device is mounted to the seat panel. The display device displays the video signal provided by the video unit. One or more compartments formed in the seat panel.

[0005] CA2630804A1 discloses about a media system for a vehicle comprises a media unit including a display mounted to a seat of the vehicle, a databus line running from the media unit through the seat, and a plurality of media sources electrically connected to the databus line. The databus line may comprise optical fiber.

[0006] Conventionally, many devices are available in market for in-vehicle entertainment and user assistance. However, these are limited to basic multimedia playback, lack adaptive comfort features, provide minimal personalization, and do not actively respond to user posture, environmental conditions, or health-related requirements during extended travel durations.

[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 entertainment, enhancing user comfort by guiding users toward adaptive posture and environmental adjustments, ensuring privacy, and autonomously responding to user discomfort or health indicators during vehicle travel.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0020] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[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 vehicle seat-mounted entertainment and user comfort management device that is capable of providing personalized entertainment, ensuring optimal viewing alignment, detecting and mitigating motion sickness, guiding posture, offering privacy, adapting content based on surroundings, and enhancing overall passenger well-being during travel.

[0023] Referring to Figure 1, an isometric view of a vehicle seat-mounted entertainment and user comfort management device is illustrated, comprising a plate 101 configured to be mounted on the back of a seat in a vehicle and installed with a touch interactive display unit 102 via a telescopically operated rod 103, a camera 104 installed on the plate 101, a motorized ball and socket joint 105 integrated between the plate 101 and rod 103, a posture guidance module 106 comprising a speaker 106a and a holographic projection unit 106b provided with the plate 101, a pair of motorized sliders 107 installed on both sides of the plate 101, each connected to a motorized roller 108 with rolled acrylic sheets, a pair of L-shaped telescopic links 109 with motorized clippers 110 provided with the plate 101, a microphone 111 is installed on the plate 101, a horizontal panel 112 is attached to a bottom of the vertical plate 101, a protective flap 113 integrated with the plate 101 via an extendable bar 114.

[0024] The device disclosed herein includes a plate 101 developed to be mounted on a back of a seat in a vehicle. The plate 101 herein includes all component of the device to offer both entertainment and comfort at same time.

[0025] In a preferred embodiment of the present invention, a user must activate the device by pressing a push button, installed on the plate 101. The push button is accessed by the user for activating the device. 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 the device.

[0026] When the push button is pressed, the button sends a signal (usually a change in voltage or current) to an inbuilt microcontroller associated with the device to either power up or shut down the microcontroller. Conversely, releasing the button allows the spring to return to its original position, breaking the circuit and sending the signal to deactivate the device. The microcontroller is pre-fed to detect this signal and respond accordingly. The microcontroller used herein is pre-fed using artificial intelligence and machine learning protocols to coordinate the working of the device.

[0027] In an embodiment of the present invention, the plate 101 is securely mounted on the back of the vehicle seat using multiple clamps. These clamps are powered by the DC (Direct Current) motor, which is actuated by the microcontroller through the supply of an appropriate electrical current. The DC motor comprises a coil that, upon receiving the electric current, generates a magnetic field, thereby converting electrical energy into mechanical force. This mechanical force drives the operation of the clamps, enabling their controlled extension and retraction. As a result, the clamps firmly engage or release the plate 101 from the seat surface as required, ensuring stable installation and allowing for potential repositioning or removal when necessary.

[0028] A camera 104 mounted on the plate 101 for detecting the presence of a user within a predefined distance. The camera 104 comprises an image capturing module including a set of lenses that captures multiple images of the surrounding environment. The captured images are stored within the memory of the camera 104 in the form of optical data. The camera 104 further comprises a processor embedded with artificial intelligence protocols. This processing involves essential image processing steps such as noise reduction to enhance image clarity, feature extraction to identify relevant characteristics of the user (e.g., shape, color, size), and techniques such as segmentation to isolate the user from the background. Simultaneously, a proximity sensor mounted on the plate 101 is activated by the microcontroller to work in sync with the imaging unit to measure the distance between the user and the plate 101 to confirm presence within a predefined range. The data from the camera 104, along with the proximity sensor signals, are converted into digital pulses and bits and transmitted to the microcontroller. The microcontroller processes the received data to accurately detect the presence, position, and movements of the user.

[0029] The proximity sensor used herein is preferably an ultrasonic proximity sensor that uses ultrasonic waves to detect the presence of the user within a predefined distance. The ultrasonic proximity sensor typically emits ultrasonic waves towards the user, which reflect off the user and bounce back to the sensor’s receiver. The receiver of the ultrasonic proximity sensor is sensitive to the emitted ultrasonic waves and listens for the reflected signals. Upon receiving the reflected ultrasonic waves, the proximity sensor sends the corresponding data to the microcontroller, which processes and analyzes the acquired data to accurately detect the presence and proximity of the user.

[0030] A touch interactive display unit 102 is installed on the plate 101 via a telescopically operated rod 103 for adjustable positioning relative to the user. The telescopic rod 103 enables extension and retraction of the display unit 102 to accommodate different seating arrangements and user preferences. The display unit 102 is configured to provide visual content and interactive functionality, allowing the user to control entertainment, comfort settings, and other features through touch input.

[0031] The touch interactive display unit 102, commonly known as a touchscreen, is an electronic visual display that detects both the presence and precise location of a user’s touch within the display area. In a preferred embodiment of the present invention, the touch interactive display unit 102 comprises multiple layers, including a display panel, a touch sensor, and a controller.

[0032] The display panel, typically a liquid-crystal display (LCD), forms the outermost layer and is responsible for rendering the visual content. Beneath this panel lies the touch sensor, usually made of a transparent conductive material such as indium tin oxide (ITO). The touch sensor is organized into a grid of rows and columns, where each intersection corresponds to a unique touch point.

[0033] When the user touches the display surface, the conductive properties allow electrical signals to change at the specific point of contact. This change is detected by the touch sensor, which transmits the raw data to the controller. The controller processes this data by filtering out noise and interference, accurately determining the exact location of the touch. Once the touch location is identified, the controller sends this information to the microcontroller, which interprets the user input and executes corresponding commands to control the device’s various functions, such as adjusting display settings, navigating menus, activating comfort features, or managing entertainment options.

[0034] The telescopically operated rod 103 is linked to a pneumatic unit, comprising an air compressor, air cylinders, air valves, and a piston, which work in collaboration to facilitate the extension and retraction of the rod 103. The pneumatic unit is controlled by the microcontroller, which actuates the air valves to allow the passage of compressed air from the compressor into the air cylinders. The compressed air generates pressure against the piston, causing it to push outward and extend the rod 103. The piston is mechanically connected to the rod 103, and as a result of the applied pressure, the rod 103 extends accordingly. Similarly, the microcontroller controls the retraction of the telescopically operated rod 103 by closing the valve, which releases the compressed air and allows the piston to retract. Thus, the microcontroller regulates the extension and retraction of the rod 103 to adjust the position of the display unit 102 in response to user input or predefined settings.

[0035] A motorized ball-and-socket joint 105 is installed in between the plate 101 and the rod 103, controlled by a microcontroller that synchronizes its movement with the extension and retraction of the rod 103 to automatically align the display unit 102 with the user’s line of sight. The motorized ball and socket joint 105 includes a motor controlled by the microcontroller, a ball-shaped element, and a socket. The ball moves freely within the socket, allowing multi-directional movement. The motor rotates the ball in various directions under the precise control of the microcontroller, which sends commands to position the ball accurately. The microcontroller actuates the motor to generate electrical current that drives the rotation within the joint 105, thereby providing controlled movement and adjustment to the rod 103 for optimal alignment of the display unit 102 with the user’s line of sight.

[0036] A gyroscopic sensor integrated with an angle sensor is mounted on the plate 101 to detect the vehicle’s tilt. The gyroscopic sensor and angle sensor function collectively to determine the tilt and orientation of the vehicle. The gyroscopic sensor operates by detecting angular velocity—measuring the rate of rotation around one or more axes—using the Coriolis effect within vibrating structures or MEMS components, thereby providing real-time data on changes in the vehicle’s rotational movement and dynamics. The angle sensor, commonly realized as an accelerometer or inclinometer, measures the static angle or inclination of the vehicle relative to a reference plane, such as the horizontal ground, by sensing gravitational acceleration components. Together, these sensors continuously monitor the vehicle’s posture. The sensor outputs are transmitted to the microcontroller, which processes and analyzes the combined data to determine if the vehicle’s tilt exceeds a set threshold stored in a linked database by comparing the detected data with the threshold. Upon detection of such deviation, the microcontroller triggers the camera 104 to analyze the user’s facial expressions for signs of motion sickness, thereby enhancing passenger comfort and safety.

[0037] A posture guidance module 106 is mounted on the plate 101, comprising a speaker 106a and a holographic projection unit 106b that work in conjunction to prompt the user to maintain correct posture and enhance overall comfort during travel. The speaker 106a functions by converting electrical signals into audible sound. The speaker 106a consists of a diaphragm (cone) attached to a voice coil positioned between two magnets. When an electrical signal is passed through the voice coil, it generates a varying magnetic field that interacts with the permanent magnetic field of the surrounding magnets. This interaction causes the diaphragm to vibrate, moving back and forth. The diaphragm’s movement pushes and pulls air particles, producing sound waves that replicate the original electrical signal, thereby audibly notify the user about posture corrections or comfort-related prompts. Additionally, if the microcontroller detects facial expressions indicating high discomfort or motion sickness, the speaker 106a advises the user to hydrate and/or take rest. Simultaneously, alerts are sent to a driver or onboard staff on a computing unit associated with the driver or onboard staff, while soothing content is played on the display unit 102 to help ease the user's discomfort.

[0038] A communication module linked with the microcontroller is activated by the microcontroller for establishing a 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 driver and onboard staff. 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.

[0039] This module also enables the user to create, store, and access personalized profiles on a cloud-based database linked with the microcontroller. This module facilitates synchronization of user-specific settings and preferences across journeys. The user retrieves previously accessed content or settings by entering login credentials through the touch display unit 102 or an associated computing device. This ensures a seamless and customized user experience by maintaining continuity of preferences, content history, and usage data, even across different vehicles or travel sessions.

[0040] The holographic projection unit 106b operates by generating and displaying holograms—three-dimensional images formed through the interference of light waves. The process begins with a laser beam emitted by the projector, which is split into two separate beams: the object beam and the reference beam. The object beam is directed toward the subject (e.g., a virtual posture model or guidance figure), and the light waves are altered based on the subject’s shape and surface features. The reference beam, in contrast, remains unaltered. These two beams are then redirected to intersect, and their interference creates a distinct interference pattern. This pattern is recorded onto a photosensitive medium, such as a holographic plate or film. The recorded interference pattern encodes information about both the amplitude and phase of the light waves, preserving the complete three-dimensional representation of the subject.

[0041] During projection, a laser beam is directed onto the recorded interference pattern, which diffracts the light and reconstructs the original wavefronts of both the object and reference beams. This reconstruction produces a three-dimensional holographic image that appears to float in space in front of the user. The image is used to demonstrate correct posture, simulate ergonomic positioning, or guide the user visually toward improved seating alignment, thereby enhancing user awareness and overall comfort.

[0042] For example: during a long road trip exceeding two hours, the device detects that the user has been seated for an extended duration. In response, the microcontroller activates the holographic projection unit 106b, which begins projecting three-dimensional fitness-related posture prompts in front of the user. These holograms include visual guides for neck stretches, back straightening, or leg movement exercises. The speaker 106a simultaneously provides verbal instructions, ensuring the user follows along correctly. This proactive functionality helps reduce physical strain, encourages better circulation, and enhances overall travel comfort and well-being.

[0043] A microphone 111 is installed on the plate 101 enables the user to input voice commands regarding activation of a privacy feature. The microphone 111 consists of a small diaphragm attached to a moving coil positioned within a magnetic field. When sound waves, such as the user's speech, strike the diaphragm, it causes the coil to vibrate. As the coil moves back and forth within the magnetic field, it induces an electrical current corresponding to the sound signal. This electrical signal is then transmitted to the microcontroller, which processes the input to recognize and execute the user’s voice command—such as initiating the deployment of privacy curtains.

[0044] A pair of motorized sliders 107 is installed on either side of the plate 101, each connected to a motorized roller 108 that holds rolled acrylic sheets. Each motorized slider typically consists of a motor-driven carriage mounted on a linear rail, enabling controlled horizontal movement of the acrylic sheets. When actuated by the microcontroller, the motor drives the carriage along the rail, allowing for smooth and precise sliding motion. This controlled linear displacement ensures accurate deployment and retraction of the acrylic sheets to form or retract the privacy enclosure.

[0045] The motorized roller 108 comprises a cylindrical roller connected to a motor via a rotating shaft. Upon receiving an actuation signal from the microcontroller, the motor generates rotational motion, which is transferred through the shaft to the roller 108. This rotation causes the acrylic sheet to either unroll or retract, depending on the motor’s direction of rotation. The coordinated operation of the motorized sliders 107 and rollers ensures synchronized and automated extension of the acrylic sheets, which are further secured into place using motorized clippers 110 mounted on a pair of L-shaped telescopic links 109 installed with the plate 101 to form a functional privacy curtain around the display unit 102.

[0046] The extension/retraction of the links 109 is regulated by the microcontroller by in the same manner as the telescopically operated rod 103, by employing the pneumatic unit. The microcontroller actuates the air valves to control the flow of compressed air from the compressor into the pneumatic cylinders connected to the telescopic links 109. This air pressure drives the pistons, causing the links 109 to extend or retract as needed. This enables precise and automated deployment of the privacy curtain by positioning the motorized clippers 110 to grip or release the acrylic sheets accordingly.

[0047] The motorized clippers 110 typically consist of a small electric motor connected to a gear-driven arrangement that controls the movement of a pair of gripping jaws or clamps. When the microcontroller sends a signal to actuate the clipper, the motor engages the gear to move the jaws into a closed position, firmly gripping the edge of the acrylic sheet. This clamping action ensures that the sheet remains taut and properly aligned as it is extended into position. Conversely, to release the sheet, the microcontroller reverses the motor’s direction, causing the gear to open the jaws, thereby disengaging the sheet.

[0048] In an embodiment of the present invention, a limit switches or sensors is integrated into the clippers 110 to provide feedback to the microcontroller, confirming whether the sheet has been successfully gripped or released. For example: When the motorized clipper is commanded to close and grip the acrylic sheet, the limit switch positioned inside the clipper housing detects when the jaws have fully closed. Once this limit is reached, the switch sends a signal back to the microcontroller, confirming that the sheet is securely gripped. Similarly, when the microcontroller initiates the release action, the motor opens the jaws, and another limit switch detects the fully open position, signaling that the sheet has been successfully released. In addition, proximity sensors or force sensors are used to detect whether the clipper is in contact with the sheet and applying adequate pressure—ensuring a secure grip without damaging the material.

[0049] A GPS (Global Positioning System) module is integrated with the microcontroller to track the vehicle’s real-time location. The GPS module operates as a satellite-based navigation system, where multiple satellites orbiting the Earth continuously transmit signals containing their precise location and the exact time the signals are sent. These signals travel at the speed of light and are received by the GPS module installed in the device. The GPS module calculates the time taken for each satellite’s signal to reach the receiver, enabling it to determine the distance from each satellite. By acquiring signals from four or more satellites, the module calculates the distance to each and employs trilateration—a geometric technique—to pinpoint the exact location of the vehicle. Using this method, the GPS module continuously fetches accurate, real-time location coordinates, which are then utilized by the microcontroller to provide relevant travel-related content and services to the user. For example: based on the current geographic coordinates, the microcontroller displays information related to nearby landmarks and provides destination-based travel updates through the display unit 102 and speaker 106a.

[0050] A horizontal panel 112 is affixed to the bottom of the vertical plate 101 and is configured to hold medical prescription sheets in a secure and readable position. The panel 112 is integrated with a OCR (Optical Character Recognition) module that operates in coordination with the camera 104 to scan and interpret the content of the medical prescriptions.

[0051] When a prescription is placed on the horizontal panel 112 attached to the bottom of the plate 101, the integrated camera 104 captures a high-resolution image of the document. This image is transmitted to the OCR module, which initiates a series of preprocessing steps including noise reduction, contrast enhancement, and alignment correction to optimize the image for text recognition. The OCR module then segments the image into lines, words, and characters. Using pattern recognition techniques and trained protocols, the module identifies printed or handwritten characters and converts them into machine-readable digital text. The extracted text is analyzed to identify relevant medical instructions from the prescription, such as dosage timing, or posture recommendations.

[0052] A protective flap 113, installed with the plate 101 through an extendable bar 114, is positioned, extend and tilt over the display unit 102 when the camera 104 detects an object approaching the display, thereby shielding it from potential impact or damage. The extension/retraction of the bar 114 is regulated by the microcontroller by in the same manner as the rod 103, by employing the pneumatic unit, for deploying or returning to its resting position based on real-time detection data.

[0053] The display unit 102 also automatically adjust the type of content it presents based on the time of day and ambient lighting conditions within the vehicle, as detected through an integrated LDR (Light Dependent Resistor). The LDR (Light Dependent Resistor), also known as a photoresistor, is a light-sensitive component that detects changes in ambient lighting conditions within the vehicle. The LDR functions based on the principle that its electrical resistance varies with the intensity of incident light. The LDR is made of a semiconductor material, such as cadmium sulfide (CdS), whose conductivity increases as light intensity increases. Under low-light conditions (such as during evening or night), the resistance of the LDR is high, resulting in a lower current flow. Conversely, in bright environments (such as during daytime), the resistance drops significantly, allowing more current to pass through the circuit. This varying electrical signal is continuously monitored by the microcontroller, which interprets the ambient light level inside the vehicle. By correlating this data with the real-time input from the GPS module, the microcontroller determines the appropriate time of day and automatically adjusts the content displayed on the screen—showing informative content in brighter morning conditions and shifting to more relaxing, music-based content during dim evening settings.

[0054] For example: during a morning commute, the device detects bright ambient light through the LDR and identifies the time as 8:30 AM using the internal clock. In response, the display unit 102 presents informative content such as weather updates, traffic conditions, and news headlines to keep the user informed. Later in the day, around 7:00 PM, the LDR senses dimmer lighting inside the vehicle, and the device recognizes it as evening. The display then automatically transitions to playing soothing music and ambient visuals, helping the user unwind and enhancing overall travel comfort.

[0055] A sun sensor integrated with the plate 101 detects both the intensity and direction of sunlight. The sun sensor typically consists of an array of photodiodes or photodetectors arranged on the plate 101 to measure sunlight intensity and determine its direction. Each photodiode generates an electrical current proportional to the amount of sunlight it receives. By comparing the output levels from multiple photodiodes positioned at different angles, the sensor accurately calculates the direction from which the sunlight is coming. The intensity of sunlight is determined by measuring the magnitude of the current produced by the photodiodes, which varies with light strength. These electrical signals are transmitted to the microcontroller, which processes the data to assess both the angle and brightness of the sunlight relative to the display unit 102. Using this information, the microcontroller repositions or tilts the display unit 102 using the telescopically operated rod 103, effectively reducing glare and enhancing screen visibility for the user under varying sunlight conditions.

[0056] The present invention work best in the following manner, where the plate 101 mounted on the back of the vehicle seat and installed with the touch interactive display unit 102 via the telescopically operated rod 103. The display unit 102 is aligned to the user’s line of sight using the motorized ball and socket joint 105 controlled by the microcontroller in sync with the rod’s extension or retraction. The camera 104 and the ultrasonic proximity sensor detect the presence of the user within the predefined distance. The gyroscopic sensor integrated with the angle sensor detects vehicle tilt, and when deviation exceeds the threshold, the camera 104 analyzes facial expressions to detect motion sickness. If high discomfort is detected, the speaker 106a advises hydration or medication, alerts are sent to the driver or staff, and soothing content is played. The posture guidance module 106 comprising the speaker 106a and the holographic projection unit 106b prompts the user on correct posture and displays fitness postures if travel time exceeds the threshold. The microphone 111 accepts speech commands to activate the privacy feature. The pair of motorized sliders 107 and rollers 108 deploy rolled acrylic sheets, while the L-shaped telescopic links 109 with motorized clippers 110 grip the sheets to form the privacy curtain. The GPS module displays travel-related content, while the OCR module reads medical prescriptions and adjusts the display accordingly. The sun sensor repositions the display to counter sunlight, and the LDR enables automatic content adjustments based on ambient light and time of day.
