Description:FIELD OF THE INVENTION

[0001] The present invention relates to a driver behaviour monitoring and infotainment obscuration system that is developed to dynamically regulate driver attentiveness and engagement during vehicle operation by performing real-time monitoring of driver focus, environmental conditions, and passenger activity, thereby improving road safety, reducing the risk of distraction-induced accidents, and enhancing the driver’s operational comfort without reliance on manual oversight.

BACKGROUND OF THE INVENTION

[0002] In everyday driving, infotainment systems have long been used to help with navigation, music, and other basic functions. Traditionally, these systems include a screen fixed to the dashboard and buttons or knobs for control. Some may even offer limited voice commands. However, while these setups offer convenience, they often become a source of distraction. For instance, if a driver takes their eyes off the road to adjust music or check directions, even for a moment, it increases the risk of accidents. These traditional units do not respond to the driver's level of attention or emotions and fails to adjust based on external factors like glare from sunlight. They also don’t restrict access to sensitive content when unknown individuals are inside the car. As a result, these basic systems fall short in helping drivers stay focused, safe, and emotionally stable during the drive, especially in complex or high-stress traffic situations.

[0003] Early vehicle infotainment systems integrating CD players, AM/FM radios, and later navigation systems. Interaction remained manual, and displays were often small, monochrome, and fixed in position. These systems do not recognize driver distraction or fatigue. Also, these fails to offer correction if the driver is inattentive or emotionally unfit to drive. So, people also use touchscreen interfaces & integrated media as these replaces physical buttons for many functions. Navigation, media, and Bluetooth connectivity became standard. However, these systems still required significant visual and cognitive attention, with no built-in awareness of the driver’s focus or emotional state.

[0004] GB2498793A discloses about an invention that includes an apparatus for monitoring driver behavior includes a plurality of sensing units including an accelerometer, a gyroscope and a magnetometer which provide data signals to a microcontroller, which processes the data signals received. The microcontroller is in turn connected to a wireless transmitter, by means of which data can be transmitted from the apparatus to a remote location. The microcontroller may be configured to process the data signals received from the sensing units to identify driving events, with data relating to the driving events being transmitted to the remote location. Alternatively, the apparatus may transmit raw data received from the sensing units to the remote location for processing. A positioning system receiver, such as a GPS receiver, may also be provided. The apparatus may be connected to an electrical outlet of the vehicle and may be able to detect disconnection from the outlet using switches associated with retaining clips within the connector. Location and time data may be recorded when disconnection is sensed for comparison with location and time data on reconnection. The information collected may be of use to insurance companies and is simple to install and calibrate.

[0005] US20210011618A1 discloses about an invention that includes an infotainment computer device for use in controlling an infotainment system in a vehicle is provided. The infotainment computer device includes at least one processor communicatively coupled to at least one memory device and a display device communicatively coupled to the at least one processor. The infotainment computer device is programmed to display an active page and a toolbar. The active page includes a plurality of buttons and the toolbar includes a shortcut area including at least one shortcut button. The infotainment computer device is also programmed to receive a first input requesting access to a customization mode, retrieve a current speed of the vehicle, activate the customization mode if the current speed of the vehicle is zero, receive a second input indicating a desired change to at least one of the active pages and the toolbar, and change the display based on the desired change.

[0006] Conventionally, many systems have been developed that are capable of monitoring driver behaviour and obstructing infotainment functionalities during instances of detected distraction. However, such systems often lack adaptive responsiveness to diverse distraction triggers and fail to address the driver's emotional state or the contextual factors influencing inattentiveness. Additionally, these existing systems fail to effectively filter or suppress non-critical information during high-demand driving states and do not restore comprehensive access in low-distraction scenarios, thereby reducing the relevance and contextual appropriateness of content delivery during varying driving conditions

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system that is capable of identifying emotional or psychological states of the vehicle operator and adjusting audio-visual feedback or displayed media to counteract negative emotional conditions, thereby supporting consistent driver attentiveness. In addition, the developed system also filtering or suppressing non-critical information during high-demand driving states and restoring comprehensive access in low-distraction scenarios, thus improving content delivery relevance relative to the driving context.

OBJECTS OF THE INVENTION

[0008] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0010] Another object of the present invention is to develop a system that is capable of autonomously redirecting driver attention to the roadway upon detection of behavioural indicators suggestive of cognitive disengagement, thus promoting sustained situational awareness.

[0011] Yet another object of the present invention is to develop a system that is capable of dynamically adjusting the visibility, orientation, and accessibility of information displays based on real-time user behaviour and ambient conditions, thereby ensuring ergonomic interaction while minimizing potential visual interference.

DETAILED DESCRIPTION OF THE INVENTION

[0018] 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. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0019] 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.

[0020] 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.

[0021] The present invention relates to a driver behaviour monitoring and infotainment obscuration system that enables live monitoring of the driver’s eye direction to notice when they stop paying attention or keep looking elsewhere, thereby ensuring mitigation of safety threats arising from diminished situational awareness.

[0022] Referring to Figure 1, a perspective view of a driver behaviour monitoring and infotainment obscuration system is illustrated, comprising a camera 101 associated with the system developed to be mounted on a vehicle infotainment unit 100, a speaker unit 102 embedded within inner cabin of the vehicle, a spherical joint 103 integrated with a rear portion of the infotainment unit 100, a covering arrangement provided with an apex portion of the infotainment unit 100, comprises a panel 104 mounted on a motorized hinge 105 attached to the apex portion of the infotainment unit 100.

[0023] Figure 1 further illustrates a motorized slider 106 mounted along an edge of the infotainment unit 100, a tint expandable glass 107 attached with the sider via a series of motorized ball and socket joint 108, an extendable rod 109 installed adjacent to the infotainment unit 100 and integrated with a rubberized tip 110 as an end-effector, a microphone 111 is integrated with inner cabin of the vehicle, a liquid fragrance dispersion unit is operatively integrated within the vehicle cabin and comprises a sealed chamber 112 connected with a nozzle 113.

[0024] The system disclosed herein comprising a camera 101 integrated with the vehicle infotainment unit 100 to detect and monitor the gaze direction of the driver in real time. The camera 101 is mounted in a fixed position relative to the infotainment unit 100 such that it remains within the driver's forward field of view during regular vehicle operation. The camera 101 is communicatively linked to a microcontroller to analyze visual focus patterns and determine whether the driver is maintaining attention on the driving environment.

[0025] The camera 101 continuously captures high-resolution images of the driver’s face and eyes during vehicle operation and transmits the visual data to an onboard processing module configured with computer vision protocols. The processing module analyzes the data to track the driver’s eye movements and head orientation, thereby determining the direction of gaze.

[0026] The processed output is then transmitted to the microcontroller. If the microcontroller determines that the gaze direction has deviated from the forward driving path for a predefined threshold duration, it classifies the event as a distraction. The camera 101 operates effectively under varying lighting conditions using automatic exposure adjustments and remains continuously active during vehicle operation to ensure uninterrupted monitoring of the driver’s visual focus.

[0027] A microphone 111 is integrated within the inner cabin of the vehicle and is operatively coupled with the microcontroller. The microphone 111 is configured to receive voice-based input from the vehicle operator during vehicle operation. Upon capturing the voice commands, the microphone 111 converts the acoustic signals into corresponding electrical signals and transmits the same to the microcontroller. The microcontroller is programmed to interpret the received signals as executable commands associated with infotainment unit 100 functionalities, thereby facilitating hands-free control of infotainment features. This configuration enables real-time interaction with the infotainment unit 100 without requiring manual input from the driver.

[0028] The microphone 111 functions by capturing sound waves produced by the driver's voice and converting them into electrical signals through a diaphragm and transducer. These analog signals are then passed through an internal amplifier and an analog-to-digital converter (ADC) to generate digital audio data. This digital data is transmitted to the microcontroller via a predefined interface for further processing. The microphone 111 remains continuously active during vehicle runtime and employs noise reduction techniques to filter ambient sounds, thereby enhancing the clarity of captured voice commands. The processed commands enable the execution of predefined infotainment operations without manual intervention.

[0029] A speaker unit 102 is embedded within the inner cabin of the vehicle and is operatively linked to the microcontroller. The speaker unit 102 is configured to generate audible alerts in response to detection of prolonged visual focus of the driver away from the forward driving direction. Upon identification of such distraction events by the camera 101, the microcontroller transmits a corresponding signal to the speaker unit 102 to initiate an alert. The alert may include pre-configured audio tones, voice prompts, or warning messages designed to redirect the driver's attention back to the roadway, thereby mitigating distraction-induced driving risks.

[0030] The speaker unit 102 receives digital audio signals from the microcontroller, which are first decoded through a digital-to-analog converter (DAC). The resulting analog signal is then amplified and transmitted to a diaphragm within the speaker. Vibrations in the diaphragm create pressure waves in the surrounding air, producing sound audible to the driver. The speaker unit 102 may emit varied tones, volume levels, or voice-based alerts depending on the severity and type of distraction detected. The speaker unit 102 is acoustically calibrated to ensure clarity under operational noise conditions within the vehicle, thereby ensuring the driver reliably receives the attention-directing audio prompt.

[0031] Also, the speaker unit 102 deliver customizable audio alerts in response to driver distraction events, wherein the alerts include adjustable parameters such as tone, volume, and frequency. Upon detection of prolonged driver inattention by the camera 101, visual data is transmitted to the processing module, which analyzes gaze direction and duration. This analyzed data is then communicated to the microcontroller, which evaluates the severity and persistence of the distraction.

[0032] Based on this evaluation, the microcontroller issues corresponding control signals to the speaker unit 102 to emit an appropriate auditory prompt. The microcontroller further assesses subsequent visual input from the camera 101 to determine whether the driver has responded, and modifies future alerts accordingly. This closed-loop response enhances the efficacy of auditory interventions aimed at refocusing the driver’s attention on the roadway.

[0033] In an embodiment of the present invention, upon sensing prolonged visual focus of the driver on the infotainment unit 100, the microcontroller issues an audible alert via the speaker unit 102, wherein the duration of the focus is continuously monitored and, upon exceeding a predefined threshold time frame, the speaker unit 102 is actuated to emit one or more audio alerts. The nature, tone, and volume of the alerts are calibrated based on the elapsed duration of the distraction, such that if the driver’s visual attention remains diverted beyond the threshold, the speaker delivers progressively intensified alerts to prompt refocusing on the roadway.

[0034] A spherical joint 103 is integrated at the rear portion of the infotainment unit 100, configured to facilitate automated multidirectional adjustment of the physical orientation of the infotainment unit 100. Upon non-responsiveness of the driver to an issued audio alert, as detected by the camera 101 and processed via the microcontroller, the spherical joint 103 receives actuation signals from the microcontroller to reorient the infotainment unit 100 toward or away from the driver. This adjustment is intended to regain the driver’s attention by dynamically altering the visual position of the infotainment unit 100 in accordance with the driver’s detected gaze behaviour or continued inattention.

[0035] The spherical joint 103 receives actuation commands from the microcontroller when the driver fails to respond to an issued auditory alert. These commands are based on real-time visual data received from the camera 101 and processed by the onboard module. Upon command, internal actuators within the joint rotate along multiple axes, allowing the infotainment unit 100 to tilt, swivel, or pivot in a controlled manner. This reorientation aligns the infotainment unit 100 in a new physical direction to either interrupt visual fixation or redirect attention. The spherical structure allows seamless multidirectional movement, ensuring ergonomic repositioning without mechanical constraints or limited angular displacement.

[0036] Also, the spherical joint 103 enables multidirectional tilting of the infotainment unit 100, thereby allowing precise and ergonomic repositioning of the unit’s display surface. The joint is operatively coupled to the microcontroller, which transmits actuation signals based on driver-specific behavioural inputs, including gaze orientation or positional discomfort. Upon receipt of such signals, the spherical joint 103 permits angular displacement of the infotainment unit 100 along multiple axes without mechanical obstruction, enabling the unit to be tilted, rotated, or swivelled in a controlled manner. This configuration facilitates personalized display alignment conducive to optimal visibility, reduced physical strain, and enhanced operational accessibility during vehicle use.

[0037] A covering arrangement is structurally affixed to the apex portion of the infotainment unit 100 and comprises a panel 104 mounted on a motorized hinge 105. The hinge 105 is operatively controlled by the microcontroller, which receives input based on prolonged visual focus by the driver. Upon continued detection of driver distraction beyond a predefined threshold duration, the microcontroller issues actuation signals to a motor integrated with the motorized hinge 105, causing the panel 104 to shift from a retracted position, wherein the infotainment display screen is visible, to an extended position, and is fully obscured. This serves to eliminate visual access to the infotainment interface during periods of sustained inattention, thereby enforcing visual disengagement and enhancing road safety.

[0038] The microcontroller sends an actuation signal to the motor integrated within the hinge 105. The motor converts the electrical signal into mechanical rotary motion. This rotary motion drives the hinge 105 to pivot, thereby moving the attached panel 104 from the retracted position to the extended position. The panel 104 remains extended until the microcontroller issues a reverse signal. Upon receipt of the reverse signal, the motor reverses its rotation, causing the hinge 105 to retract the panel 104 back to its original position. This sequence is executed in response to the operational commands generated based on driver attention data received by the microcontroller.

[0039] Thereafter the microcontroller herein is operatively integrated with a database comprising pre-identified user profiles stored in its memory. During vehicle use, the microcontroller processes incoming identification-related data and attempts to match the data against the stored profiles. Upon a successful match, access to personalized infotainment features is permitted based on the preferences associated with the verified profile. In the event the incoming data does not correspond to any pre-identified user profile, the microcontroller classifies the user as unidentified and restricts access to only non-personalized features. This enables selective feature availability based on user classification, thereby preserving data privacy and functional configuration.

[0040] A sun sensor is embedded within the infotainment unit 100 and is configured to detect the directional intensity and position of incident sunlight relative to the vehicle cabin. The sun sensor continuously measures the angle and intensity of incoming sunlight using photodiode arrays arranged in a quadrant layout. Variations in light received by each quadrant are converted into electrical signals that indicate the sun’s position relative to the sensor. These signals are transmitted to the microcontroller, which interprets the glare intensity and direction in real time. Upon determining that the sun glare poses a potential visual disturbance to the driver, the microcontroller initiates corrective action.

[0041] A motorized slider 106 is operatively mounted along an edge portion of the infotainment unit 100 and is functionally coupled with a tint expandable glass 107. Upon identification of excessive sunlight or directional glare, as determined by the sun sensor and processed by the microcontroller, a control signal is transmitted to the motor integrated with the slider 106. In response, the motorized slider 106 initiates a controlled deployment of the tint glass 107. The glass 107 is movably connected through a series of motorized ball and socket joints 108 that facilitate angular adjustments, enabling precise positioning to effectively block the incident glare and preserve screen visibility and driver comfort.

[0042] Upon receiving an actuation signal from the microcontroller, the motor integrated within the slider 106 engages its drive arrangement. This drives the slider 106 along a pre-defined linear track situated on the edge of the infotainment unit 100. As the slider 106 moves, it carries the attached tint expandable glass 107 forward into a deployed position. The slider 106 continues motion until it reaches its terminal point or until the microcontroller terminates the drive signal. Once deployed, the tint glass 107 serves to obstruct sun glare, thereby reducing visual strain and enhancing operational clarity of the display screen of the infotainment unit 100.

[0043] Each motorized ball and socket joint 108 comprise a rotatable spherical element enclosed within a housing that enables multi-axis rotation. When deployment of the tint glass 107 is initiated, the microcontroller sends electrical signals to miniature servo motors integrated within the joints. These motors actuate the spherical components to adjust the angular orientation of the attached glass 107 pane. The jointed movement allows dynamic reconfiguration of the glass 107 surface based on the incident angle of sunlight. Upon reaching an optimal tilt position to block glare, the motor halts motion and maintains the angle through electronic position locking, ensuring stable glare mitigation during operation.

[0044] An extendable rod 109 is strategically positioned adjacent to the infotainment unit 100 and includes a rubberized tip 110 configured as an end-effector. This rod 109 is operable to alter the currently playing media content in response to detected adverse emotional states of the driver, as determined through visual or behavioural cues processed by the microcontroller. Upon such detection, the microcontroller issues an actuation signal to the pneumatic unit, which in turn activates the rod 109. The controlled actuation enables the rod 109 to make physical contact with the infotainment interface, thereby executing a media change action aimed at supporting emotional stabilization and promoting attentive driving behaviour.

[0045] Upon receiving the actuation command from the microcontroller—based on real-time driver emotion recognition—the pneumatic unit initiates the mechanical extension of the extendable rod 109 through a coordinated sequence of actions. The solenoid valve within the pneumatic unit acts as the interface between the microcontroller’s electronic signal and the pneumatic unit mechanical output.

[0046] Once the microcontroller transmits the actuation signal, the solenoid coil is energized, triggering the valve to shift its position. This change allows compressed air, previously generated and stored by an integrated air compressor, to flow through the unit. Before reaching the actuating chamber, the air pressure is stabilized via a pressure regulator, ensuring consistent and safe force application. The regulated pressurized air is then routed into the actuating cylinder, where it pushes the internal piston. The piston’s movement causes the extendable rod 109 to protrude outward. At full extension, the rod 109—terminating in the rubberized end-effector—makes contact with the infotainment screen to initiate a media content change, thereby supporting positive emotional regulation of the driver. Once the interaction is completed, the solenoid valve reverses airflow direction, causing the piston to retract and the rod 109 to return to its original position.

[0047] A facial recognition module is operatively integrated with the camera 101 configured within the system for the purpose of real-time identification and analysis of the driver’s facial expressions. The captured visual data is continuously processed to determine emotional indicators through recognition of expression patterns. Upon detection of a negative affective state, specifically a sad emotional condition, the data is transmitted to the microcontroller.

[0048] In response, the microcontroller initiates re-actuation of the extendable rod 109. The rod 109 is thereby deployed to interact with the infotainment unit 100 to autonomously alter the currently playing media content. This action is intended to induce a positive shift in the driver’s emotional state and maintain psychological stability, thereby promoting sustained attentiveness during vehicle operation.

[0049] Synchronously, the microcontroller herein detects the activation of a navigation interface within the infotainment unit 100 and, in response, execute control signals to initiate mechanical reorientation of the unit toward the driver's seating position. This dynamic repositioning is carried out through spherical joint 103 supporting the infotainment unit 100, thereby aligning the display at an optimal viewing angle relative to the driver's line of sight. Such directional adjustment enhances the legibility and accessibility of navigation-related visual information, minimizing the need for extended glances or head movement, and consequently supporting safer and more efficient interaction with route guidance features during active vehicle operation.

[0050] Further the microcontroller, upon detecting the presence of unfamiliar occupants within the vehicle cabin based on comparison against stored identification data, initiates an actuation signal to deploy the covering arrangement configured to obscure the infotainment unit 100 display. The concealment is maintained as a security measure to prevent unauthorized access or interaction with infotainment features. The covering arrangement remains in the obscured position until the microcontroller receives an explicit voice command from a verified or authorized user, at which point a reversal signal is issued to retract the covering, thereby restoring normal access. This selective concealment protocol ensures controlled access to personalized or sensitive content within the infotainment environment.

[0051] Furthermore, the microcontroller is pre-programmed with operational logic configured to dynamically suppress non-essential notifications and reduce visual complexity of infotainment content during high-load driving conditions, such as heavy traffic, complex navigation, or adverse weather. In such instances, the microcontroller filters out auxiliary prompts, streamlines interface elements, and limits display output to only critical driving-related data. Upon detection of low-load driving scenarios—such as steady cruising or minimal environmental input—the microcontroller restores full access to standard infotainment functions and comprehensive visual content. This adaptive interface modulation enhances driver focus and minimizes cognitive overload by aligning system output with real-time driving demands.

[0052] In an embodiment of the present invention, a liquid fragrance dispersion unit is operatively integrated within the vehicle cabin and comprises a sealed chamber 112 containing a liquid aromatic solution. A nozzle 113 is fluidly connected to the chamber 112 and mechanically coupled via a swivel joint, the orientation of which is adjustable under microcontroller control. An odor detection sensor is embedded within the cabin environment to continuously monitor ambient air quality.

[0053] Upon detection of an undesirable or unpleasant odor beyond a predefined threshold, the sensor transmits corresponding data to the microcontroller. In response, the microcontroller actuates the swivel joint to orient the nozzle 113 in a targeted direction and triggers the release of the aromatic solution, thereby dispensing fragrance selectively into the cabin. This configuration ensures automated and directional odor neutralization, promoting a comfortable and hygienic in-cabin atmosphere for vehicle occupants without requiring manual intervention.

[0054] The odor detection sensor continuously samples the ambient air within the vehicle cabin through an integrated sensing membrane that reacts to specific chemical compounds associated with unpleasant odors. Upon detection, the sensor measures the concentration of these volatile compounds and converts the chemical data into electrical signals. These signals are then transmitted to the microcontroller for analysis. If the signal exceeds a pre-defined odor threshold, the sensor confirms the presence of an undesirable smell. This processed data acts as a trigger input for subsequent operations.

[0055] Upon receiving a control signal from the microcontroller, a miniature motor embedded within the swivel joint activates and initiates rotation. The swivel joint, which is mechanically coupled to the nozzle 113, pivots horizontally and vertically to achieve multi-directional aiming. The degree of rotation is governed by pre-programmed parameters or sensor-based input that determines the optimal direction for fragrance dispersion. Once the desired orientation is reached, the joint holds its position while the nozzle 113 is actuated. The joint remains idle until a subsequent command requires reorientation.

[0056] When the microcontroller confirms the presence of odor and the swivel joint is positioned correctly, it sends an actuation signal to a micro-pump attached to the fragrance chamber 112. This micro-pump pressurizes the liquid aromatic solution and channels it through the nozzle 113. The nozzle 113, equipped with a spray aperture, atomizes the solution into a fine mist. The mist is then released in the pre-directed path established by the swivel joint. Once the spray duration lapses or target air quality is restored, the microcontroller signals the system to cease dispersion. The nozzle 113 then resets to standby until the next cycle.

[0057] Moreover, a battery is associated with the system for powering up electrical and electronically operated components associated with the system and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the system, derives the required power from the battery for proper functioning of the system.

[0058] The present invention works best in the following manner, where the camera 101 as disclosed in the invention is associated with the system, developed to be mounted on the vehicle infotainment unit 100 for detecting gaze direction of the driver. The microphone 111 receiving voice instructions from the driver and forwards the instructions to the microcontroller for execution, enabling hands-free control of infotainment features. The speaker unit 102 redirect the driver's attention back to the road upon detecting prolonged visual focus. Also, the speaker unit 102 delivers customizable audio alerts, including varied tones and volumes, adaptable based on the driver's response. The spherical joint 103 automatically adjusts physical orientation of the infotainment unit 100 upon non-responsiveness to the audio alert. And the spherical joint 103 enables multidirectional tilting of the infotainment unit 100, allowing ergonomic positioning adjustments based on the driver's needs. The covering arrangement fully obscure display screen of the infotainment unit 100 upon continued detection of driver distraction. The covering arrangement comprises the panel 104 mounted on the motorized hinge 105 attached to the apex portion of the infotainment unit 100. The panel 104 being movable between the retracted position exposing the display screen and the extended position fully obscuring the screen. Thereafter the microcontroller is integrated with the database stored with pre-identified user profiles and classifies unidentified users, restricting access to non-personalized features.

[0059] In continuation, the sun sensor embedded with the infotainment unit 100 detecting sun glare direction. Synchronously, the motorized slider 106 deploys the tint expandable glass 107 attached with the sider via multiple motorized ball and socket joint 108 to block the glare. The extendable rod 109 integrated with the rubberized tip 110 as the end-effector, operable to automatically change the currently playing media content to positively regulate the driver’s emotional state. Further the facial recognition module is integrated with the camera 101 for real-time analysis of facial expressions of the driver. Upon detecting the sad emotional state, the rod 109 automatically changes currently playing media content to positively regulate the driver's emotional state. Furthermore, the microcontroller is configured to reorient the infotainment unit 100 toward the driver upon activation of the navigation map, enabling improved visibility and readability of navigation details while driving. Also, the microcontroller upon detection of unfamiliar occupants inside the vehicle actuates the covering arrangement to obscure the infotainment unit 100, and only uncovers upon receiving explicit voice command from the authorized user. Moreover, the microcontroller is pre-fed to suppress non-essential notifications and simplifying visuals during high-load driving conditions, and restoring full information access in low-load scenarios.
